Detailed Description
Exemplary embodiments of the present invention are described in detail below with reference to the attached drawing figures, wherein the same or similar reference numerals denote the same or similar elements. Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the present disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in the drawings in order to simplify the drawings.
Industrial band-aids are distinguished from medical band-aids, which are an adhesive tape assembly for repair of damaged or leaking points, and are typically used for repair of pipes or cables. The industrial band-aid can be used for maintenance and prevention protection of various pipelines, cables and cable joints in various industrial and mining enterprises such as ships, mines, power plants, machines, chemical industry and the like, particularly in mining application, for maintenance and emergency repair of the pipelines, cable joints and cables, in power cables, for armoured protection of joint parts, repair of power cable jackets and outer protection of cable intermediate joints, for rapid leak-proof repair of various pipeline lines, and for armoured protection of the pipelines, and can greatly reduce various losses and rush repair cost caused by leakage and pipeline abrasion of various pipelines.
The adhesive tape of the industrial band-aid is typically formed by compounding a high-molecular material and an inorganic material, wherein the high-molecular material is mainly high-performance polyurethane and other additives, and the inorganic material is mainly high-performance and high-quality glass fiber which is obtained by braiding and sintering at high temperature. In one specific example, the tape 11 is composed of two layers of material, including a base 111 and a cured layer 112 disposed on the base 111, as shown in FIG. 5. One example of the substrate 111 is an alkali-free or low alkali fiberglass cloth, one example of the cured layer 112 is a flame retardant polyurethane prepolymer mixture, the cured layer is coated on the substrate to obtain an adhesive tape, and then the adhesive tape is vacuum packed to obtain an industrial band-aid product to be used.
The specification of the industrial adhesive bandage product prescribes the operation specification of the adhesive tape pasting, the operation specification is recommended to be strictly complied with, the compression resistance and the mechanical performance of the product can be greatly improved according to the operation specification, but in practical application, the execution of the operation specification depends on the proficiency of constructors, and the operator is expected to be assisted in executing the construction operation specification by providing a novel laying method and an auxiliary technical means.
The method of laying an industrial band-aid according to the invention is based on an industrial band-aid of the type described above, which is a water-curable industrial band-aid, and in its laying process it is preferred that the adhesive tape is brought into contact with water, for example by immersing in water, and then removed, excess water removed and the application performed. It is important that the adhesive tape contacts water and removes excessive moisture and accurately overlaps the adhesive tape as required, and furthermore, at the beginning of winding, the adhesive tape is taken out of the bag body and held by the operator all the time, if foreign particles are occupied on the glove during holding, they are likely to adhere to the adhesive tape, the adhesive force of the contaminated adhesive tape is remarkably lowered, which affects the compression resistance of the industrial band-aid, and in particular, the operator needs to press the pipe by hand during operation, so that the glove is more easily contaminated. The three operations described above may have any effect if performed with a flaw.
First, it is easily understood that the contaminated adhesive tape may reduce the adhesiveness of the adhesive tape, thereby affecting the compression resistance of the industrial band-aid; secondly, the industrial band-aid is a water-curable product, the curing time of the industrial band-aid is related to the quantity of water absorption and the volatilization of water contained in the industrial band-aid, after the adhesive tape is taken out of the bag body and water is extruded, the adhesive tape is exposed to the environment in the operation process, the water is easy to volatilize, the curing time is fast, an operator needs a certain operation time to paste the pipeline, the pipeline needs to be repeatedly pasted for a plurality of times in certain occasions, more time is needed, and the problem that the adhesive tape is cured after the adhesive tape is not pasted yet can exist; thirdly, in the step of removing the excessive water in the adhesive tape, the adhesive tape is squeezed by a human hand, so that the squeezing is uneven, the water is not removed sufficiently, and the adhesive uniformity of the adhesive tape is affected; fourth, it is unreliable to obtain the desired overlap ratio by visual inspection and experience of the operator, and it is difficult to obtain the desired overlap ratio in actual operation.
In view of the above problems, the present invention provides a new method for laying an industrial band-aid, and provides a new industrial band-aid and an industrial band-aid package in combination with the laying method. Fig. 1 to 3 are schematic views of an industrial band-aid according to an embodiment of the present invention, fig. 1 is a front view showing the appearance of the industrial band-aid package, and fig. 2 to 3 are rear views showing a sealing cover attached to an auxiliary pouch and a sealing cover removed from the auxiliary pouch, respectively.

The main bag body 1 and the auxiliary bag body 4 can be made of conventional materials for forming bag body package, can be combined together in a thermoplastic mode and can be integrally formed, the inside of the main bag body 1 is in a vacuum state, so that the periphery of the main bag body 1 is tightly sealed, and the sealing edge 2 of the main bag body 1 is provided with an easy-tearing opening 3 for facilitating the tearing of the main bag body 1; the auxiliary bag body 4 does not need to be kept in a high vacuum state, and the bag opening can be closed by adopting a buckling sealing edge 41 capable of being repeatedly opened and closed.
In order to close the auxiliary bag body 4 during storage and transportation of the product, it is necessary to close the opening 43 of the auxiliary bag body 4, here a sealing cover 42 is used, and the sealing cover 42 covers the opening 43 and is adhered to the outer periphery of the opening 43.
Considering the step of squeezing the adhesive tape, a squeezing belt is arranged in the auxiliary bag body 4, and is used for squeezing out the moisture on the adhesive tape 11 of the industrial band-aid. Thus, in the industrial band-aid package, the adhesive tape 11 and the squeeze tape are included, the adhesive tape 11 is provided in the main bag body 1, and the squeeze tape is provided in the auxiliary bag body 4, see fig. 4.

The pressing sheet 21 and the pull tab 22 may be woven fabrics, so long as they can bear a certain tensile force, and when in use, the adhesive tape 11 is placed on the pressing sheet 21, so that the pull tab 22 bypasses the adhesive tape 11 and passes through the second perforation 232, and then the handle 24 is pulled by holding the connecting buckle 23, and even pressure is applied on the adhesive tape 11, so that redundant moisture is extruded therefrom.
Preferably, a gripping portion is provided on an edge of the connecting buckle 23 away from the first through hole 231, for gripping the connecting buckle 23 by hand.
According to a preferred embodiment of the present invention, the auxiliary bag 4 includes rubber gloves therein, so that the operator can open the main bag 1 to take out the adhesive tape 11, thereby avoiding the sticky substance from adhering to the hands and keeping the adhesive tape 11 from being polluted.
The invention provides a brand new industrial band-aid package, which is characterized by comprising a main bag body and an auxiliary bag body, wherein the main bag body is mainly used for containing adhesive tapes of an industrial band-aid when the industrial band-aid package is not opened, and the auxiliary bag body is used for containing adhesive tapes of the industrial band-aid when the adhesive tapes of the industrial band-aid are adhered after being taken out from the package, that is, the auxiliary bag body is used for temporarily containing the adhesive tapes in the adhesive tape adhering process. The adhesive tape is easily polluted during the adhesive tape attaching process, for example, the non-attached part of the adhesive tape is polluted by particles and dust, which can influence the adhesive property of the adhesive tape and the repairing effect. Through setting up assisting the bag body, allow constructor to put the sticky tape in assisting the bag body in the work progress, pull out the sticky tape through assisting the opening of the bag body, avoid polluting. Accordingly, the industrial band-aid of the present invention can facilitate execution of construction operation specifications.

Before specifically describing, referring to fig. 10, the relationship between the overlap ratio and the circumference of the pipe and the width of the tape will be described with reference to fig. 10, where T is the width of the tape 11, θ is the angle formed by the line parallel to the axis of the pipe and the width direction of the tape, which is attached to the pipe at the start of winding, represents the degree of inclination of the tape, y is the length of the line parallel to the axis of the pipe, which is attached to the pipe at the start of winding, x is the length of the pipe which is not attached by the upper tape at the length y, and z is the circumference of the pipe, and then the overlap ratio s is:
s＝(y-x)/y＝1-x/y
wherein, length y and length x are respectively:
y＝T/cosθ
x＝z*tanθ
thus, s=1-z sinθ/T
Thus, the angle θ can be deduced in the case where the circumference z of the pipe to be repaired, the width T of the tape and the desired overlap ratio s are determined.
θ＝arcsin(T*(1-3)/Z)
In the repair site, the circumference z of the pipe to be repaired, the width T of the tape, and the desired overlap ratio s are determined, so that the inclination angle θ, that is, the angle of a straight line attached to the pipe at the start of winding and parallel to the axis of the pipe with respect to the width direction of the tape, can be calculated, and the determination of this angle can guide the winding of the tape through an angle indicating line to be described later. The width direction of the adhesive tape may be defined as a first direction, which is a direction perpendicular to the longitudinal extension direction of the adhesive tape on the surface of the base body.
As described above, the adhesive tape 11 includes the base 111 and the cured layer 112 provided on the base 111, and in fig. 7, the angle indicating line 113 and the overlap indicating line 114 are provided on the side of the base 111 facing away from the cured layer 112, the angle indicating line 113 being used to indicate an angle between the angle indicating line 113 and a first direction, wherein the first direction is a direction perpendicular to the longitudinal extending direction of the adhesive tape 11 on the surface of the base 111, and the overlap indicating line 114 being used to indicate a ratio of the overlap width between the upper layer to be adhered and the lower layer to be adhered to the width of the adhesive tape 11 when the adhesive tape 11 is spirally wound, wherein the overlap width is a dimension of a portion overlapping between the upper layer to be adhered and the lower layer to be adhered in the width direction of the adhesive tape 11.

Having described the industrial band-aid and the industrial band-aid packaging employed in the method of laying the present invention, the method of laying the industrial band-aid of the embodiments of the present invention will be described with emphasis.
According to the present general inventive concept, there is provided a method of laying an industrial band-aid for adhering the industrial band-aid to an object to be repaired, the method of laying performing the adhering of the industrial band-aid using an industrial band-aid package and/or an element within the industrial band-aid package as a tool.
Fig. 11 shows a flowchart of a method of laying an industrial band-aid according to an embodiment of the present invention, fig. 12 schematically shows a part of the operation of the method of laying an industrial band-aid according to an embodiment of the present invention, wherein fig. 12 comprises four sub-drawings from top to bottom, as shown in fig. 11-12, and the method of laying comprises:
step A: the method comprises the steps of carrying out basic treatment on a part to be repaired of an object to be repaired, which can be a pipeline, a cable and the like, carrying out treatment on the object to be repaired in order to ensure good repairing effect, wherein the basic treatment can comprise the steps of removing attachments on the part to be repaired, polishing the part to be repaired, roughening the surface of the part to be repaired, cleaning the part to be repaired and/or drying the part to be repaired, and the final purpose is to keep the part to be repaired clean and have adhesive force.
And (B) step (B): extruding the industrial band-aid to the part to be repaired by using the dressing, and polishing the surface of the part to be repaired; the dressing for industrial band-aid is a material suitable for filling pits and grooves in a part to be repaired, has finer granularity and adhesiveness, can be constructed by talcum powder or calcium carbonate, high polymer resin and adhesive, preferably can be constructed into a rod shape with concentric cores, is very convenient to store and use by cutting from the rod during use, can be quickly adhered, is suitable for reshaping the shape of the part to be repaired, and is suitable for surfaces made of various materials such as metal, ceramic, stone, wood, concrete, glass fiber, plastic and the like. Based on the use of the dressing bar for industrial band-aid, the step B further comprises: cutting dressing with preset dosage from a dressing rod for industrial band-aid, and uniformly pinching by hands; sticking the dressing to the part to be repaired within 3-5 minutes, and removing redundant hardening matters; and rubbing the dressing surface by hand to make the dressing surface smooth. The dressing bar for industrial band-aid contains high polymer resin component, and can be stimulated by skin sensitive people, so that soap and people need to clean hands and touch parts after the dressing bar is used.
Step C: calculating an inclination angle theta according to the width of the adhesive tape 11, the winding perimeter of the object to be repaired and the expected lap ratio, wherein the inclination angle theta is an acute angle formed by a straight line which is attached to the object to be repaired and is parallel to the axis of the object to be repaired when the winding of the adhesive tape is started and the width direction of the adhesive tape; the specific determination method has been described above, that is, in step C, the inclination angle θ is calculated using the following formula:
θ＝arcsin(T*(1-s)/z)
wherein T is the width of the adhesive tape 11; z is the winding circumference of the object to be repaired; s is the expected overlap ratio, and the overlap ratio is the ratio of the overlap width between the upper layer to be adhered and the lower layer to be adhered to the width of the adhesive tape when the adhesive tape is spirally wound, wherein the overlap width is the dimension of the overlapped part between the upper layer to be adhered and the lower layer to be adhered along the width direction of the adhesive tape.
Step D: opening an auxiliary bag body 4 of the industrial band-aid package, taking out the rubber glove and taking the rubber glove on the belt; then, tearing the main bag body 1 of the industrial band-aid package, wherein the main bag body 1 is provided with an easy-tearing opening 3, tearing the main bag body 1 through the easy-tearing opening 3, and pouring a proper amount of water into the main bag body 1, see the 1 st-2 nd sub-graph of fig. 12; a water line may be provided on the main bag 1 to indicate the amount of water to be poured, and then the adhesive tape 11 in the main bag 1 is taken out, and the squeeze water tape is taken out from the auxiliary bag 4. As an alternative, a tear-off opening may be provided at the lower corner of the main bag body 1, so that the adhesive tape 11 may not be taken out of the main bag body 1 at this time, alternatively, the tear-off opening may be torn to allow water to naturally flow out, and then the main bag body 1 may be appropriately clenched, the adhesive tape 11 may be squeezed, and part of the water may be removed, so that the adhesive tape 11 may be prevented from being brought into contact with air prematurely.
Step E: placing the adhesive tape 11 on the pressing sheet 21 of the water squeezing belt, enabling the pull tab 22 to pass through the second perforation 232 by bypassing the adhesive tape 11, and then holding the connecting buckle 23 to pull the pull handle 24 so as to squeeze out excessive water in the adhesive tape 11, see the figure 3 of fig. 12; in this step, the adhesive tape 11 and the bag body may be put together on a squeeze belt to squeeze water, in order to avoid the adhesive tape 11 from being contacted with air too early.
Step F: the sealing cover 42 on the auxiliary bag body 4 is removed, the auxiliary bag body 4 is opened again, the adhesive tape 11 is put into the auxiliary bag body 4, and the end portion of the adhesive tape 11 is exposed through the opening 43 on the auxiliary bag body 4.
Step G: according to the inclination angle θ, the inclination angle of the tape 11 with respect to the object to be repaired is determined using the angle indication line 113 on the tape 11 such that the angle of the acute angle formed by the straight line parallel to the axis of the object to be repaired, which is attached to the object to be repaired at the start of winding, and the width direction of the tape is equal to the inclination angle θ, then the tape 11 is wound, see fig. 12, fig. 4, and the tape 11 is pressed by hand to adhere the tape 11 to the object to be repaired without wrinkles.
Step H: the overlap indication line 114 is used to monitor whether the overlap ratio of the adhesive tape 11 meets the expectations during the winding process of the adhesive tape 11. The criterion for whether the expected overlap ratio is met is that the difference between the actual overlap ratio and the expected overlap ratio should be less than 1/4 of the width of the adhesive tape, and if not, the application method provides that the application should be re-performed.
Then, steps G and H are repeated a plurality of times, and the direction in which the tape 11 travels along the object to be repaired when winding the tape 11 is different for the adjacent two steps G, i.e., the adjacent two steps G, one winding from the first end to the second end of the object to be repaired and the other winding from the second end to the first end of the object to be repaired. It is further preferable that in the two steps G of the intermediate interval one step G (the winding traveling directions of the two steps G are the same), the winding directions of the winding tape 11 are opposite, that is, one clockwise winding and one counterclockwise winding. During the winding process, a little force should be applied to wind 4-10 layers according to leakage and breakage. After the winding is finished, the adhesive tape is cured and formed after about 20 minutes, and the pipeline can be normally used after about 1 hour.
Advantageously, in said step G, after the tape 11 has been wound, the tape 11 is pushed by hand several times in the winding direction. When the object to be repaired is a pipeline, the laying method further comprises the steps of closing the valve and eliminating the pressure in the pipeline before the step A.
The industrial tape of the present invention is insulated by itself, but in order to increase the insulation and to increase the breakdown resistance, the laying method further comprises winding a reinforcing insulation layer around the adhered tape.
Further, the laying method further includes: and (C) after the step B and before the step D, adhering a layer of adhesive film on the surface of the part to be repaired, wherein the roughness of the adhesive film is larger than that of the material of the object to be repaired, the adhesive film is adhered by adopting a spiral winding method, and the lap joint ratio of the adhesive film is different from that of the adhesive tape of the industrial band-aid.

Further, the method for laying the industrial band-aid of the present invention adopts the special design of the industrial band-aid package, and the package is characterized in that the industrial band-aid package comprises a main bag body and an auxiliary bag body, the main bag body is mainly used for containing the adhesive tape of the industrial band-aid when the industrial band-aid package is not opened, and the auxiliary bag body is used for containing the adhesive tape of the industrial band-aid when the adhesive tape of the industrial band-aid is adhered after being taken out from the package, that is, the auxiliary bag body is used for temporarily containing the adhesive tape in the adhesive tape adhering process. The adhesive tape is easily polluted during the adhesive tape attaching process, for example, the non-attached part of the adhesive tape is polluted by particles and dust, which can influence the adhesive property of the adhesive tape and the repairing effect. In the laying method, constructors put the adhesive tape in the auxiliary bag body in the construction process, pull out the adhesive tape through the opening of the auxiliary bag body, avoid pollution and ensure the repair effect of the industrial band-aid.
Furthermore, the laying method of the industrial band-aid adopts the special-designed water squeezing belt, which is also a tool for assisting in executing construction operation standard, when the industrial band-aid is applied, the adhesive tape needs to be put in water to contact water, because the adhesive tape based on glass fiber and high-performance polyurethane is a water-cured adhesive tape, after the adhesive tape contacts water, excessive water needs to be squeezed out, the water is squeezed out uniformly by the water squeezing belt in the laying method, the adhesive tape is put on a tabletting, the pulling piece passes through the second perforation, the pulling piece can apply force uniformly on the adhesive tape, the squeezing effect is better, the adhesive tape pasting uniformity is better, the relatively accurate curing time can be estimated according to the squeezed out degree of the water, and an operator has psychological preparation on how long to finish the pasting operation.
In addition, the method for laying the industrial band-aid utilizes the angle indication line and the lap joint indication line which are arranged on the back surface of the adhesive tape and can indicate the overlapping proportion of the upper layer and the lower layer when the adhesive tape is spirally wound, so that the construction operation standard is convenient to strictly execute. In the product using description of the industrial band-aid, the lap joint proportion of the adhesive tape in different application scenes is specified, so that the angle between the transverse edge of the adhesive tape for executing the lap joint proportion and the bus of the pipeline or the cable can be calculated according to the diameter of the pipeline or the cable to be repaired and the lap joint proportion, an operator can easily determine how much the adhesive tape inclines relative to the longitudinal axis of the pipeline or the cable to basically and accurately obtain the expected lap joint proportion by utilizing the angle indication line, and in the process of winding the adhesive tape, the lap joint indication line can be seen on the substrate to verify whether the actual lap joint proportion meets the requirement, therefore, the laying method of the industrial band-aid provides auxiliary measures for construction operation, and can conveniently execute construction operation specifications.
