Description
Technical field
The present invention relates to for obtaining flat (flat, the flat) ceramic component of glaze with large scale and reduced thickness
Method, the above-mentioned all plates (slab, slab) in this way of ceramic component are also applied for obtaining smaller ruler suitable for being advantageously used
Ceramic tile very little and of different shapes is used for clad surface, such as, such as both interior surface and outer surface of floor and wall.
Background technique
In recent years, ceramic industry department has been developed to meet the market demand, and there is presently provided the ceramics for cladding
Plate, these ceramic boards reduce its thickness while gradually having bigger size, to keep it light enough for transporting
Defeated and laying；In fact, glazed ceramic plate of today has even greater than 3m in production2Surface extend, and thickness
It is included between about 3mm and 11mm, especially between 3mm and 6mm.
In fact, the plate of these sizes makes it possible to coat very big surface, and such as, for example, building facade, limit
The quantity in the gap between an element and another element is made, and to generate the uniformity highly praised and minimalist art
Aesthetic effect.
Due to the application of specific ceramic glaze (that is, the composition for the glass surface that is suitable for usually developing under heating), institute
Glazed surface (that is, incrustation) can also be had by stating plate, obtain desired coloring or aesthetic effect.
Conventional method has the thickness greater than 6mm-7mm and moderate size for obtaining conventional glazed ceramic wall tile,
That is, substantially less than 3m2, it is in the field of business to be known as " dual firing (double-firing) ", comprising preparation made of clay material
Supporter, then be included at a temperature of between about 1050 DEG C -1100 DEG C be subjected to for the first time fire, to cause its glass
Change, realizes the glassified ceramic product for being referred to as " biscuit (biscuit) "；Then using suitable ceramic glaze make the product into
Row glazing, and then close to glass transition temperature at a temperature of further fired, purpose be obtain surface glaze glaze
Change.In fact, the glazing temperature of usually used ceramic glaze is slightly below the glass transition temperature of clay supporter.
However, the large scale glaze plate reduced for realizing thickness, this method is worthless, because burning at second
During step processed, it is frequently present of tension between supporter and glaze below, this can lead to deformation, to destroy final plate
Flatness, or crack is even resulted in, plate be efficiently used can not.
The large size plate that obtainable thickness reduces currently on the market due to the above reasons, uses referred to as " single firing "
Method obtain, wherein single operation realize constitute plate main body prefabricated clay mixture firing and surface glazing two
Person.
In other words, incrustation is carried out to the plate of unfired clay material by applying suitable glaze, and
Thereafter it is fired in single loop, wherein reaching about 1150 DEG C -1200 DEG C of temperature, to realize the burning of clay mixture simultaneously
System, that is, its vitrifying and the glazing of surface glaze.In this case, it is clear that usually used ceramic glaze has base
Equal to the glazing temperature of the glass transition temperature of clay supporter in sheet.
Finally, unfired plate is subjected to single firing under glass transition temperature in the method known to another kind, and
Then it is decorated in the cold state with suitable color, therefore is not needed any further firing；However, using this germline
System, incrustation is quite exquisite and absolutely not wear-resisting, so that plate is not suitable for use in the cladding on floor.
On the other hand, about the type of decoration, in recent years, manufacturer is to obtain to form natural material on the surface thereof
The glaze plate of the appearance of (such as, such as marble, stone, granite, timber etc.) is made that huge effort.
For this purpose, using digital printing system at present to apply glaze on the surface of plate comprising use one
A or multiple print heads, suitable for distributing specific pigment ink in the form of droplets directly on a surface in plate, and can be
Multiple identical fundamental figure units are continuously realized on entire plate surface, that is, pixel, distribution make it possible to create
Complicated form and figure.
These print systems use four color methods, or can be six color methods, and four kinds or six are loaded on print head
Kind Conventional color ink generates various tones and nuance if these ink are mixed with various percentages.
Although these print systems are in order to form the incrustation for the effect for generating natural material with overall satisfactory
Mode work, but for realize have uniform outer surface coloring plate (that is, " monotone " final effect) for, situation
Different.
In fact, as it is known by the man skilled in the art, the homogeneous glaze plate for obtaining uniform color is needed using a large amount of
Ink, this is worthless using digital printing system；Further, since identical color can be arrived with plate using four color methods
Plate is slightly different, prevent final effect is from receiving.Furthermore, it is very difficult to certain colors are obtained, such as, such as green.
In order to generate bossage, such as in order to obtain the glaze plate for showing wood grain surfaces, current molding appropriate
Mold is set in advance on the surface of unfired clay supporter, to be fired with before glazing, is applied on it
Desired bossage.
However, since it is desired that multiple molds are realized and kept in warehouse, so the flexibility of system is poor, wherein each
Mold carries specific bossage, thereby increases cost.
Summary of the invention
The main task of the purpose of the present invention is to be made pottery by providing for obtaining the glaze with large scale and reduction thickness
The method of the plate of porcelain coating the shortcomings that eliminate in the prior art, while being able to maintain that its flatness and preventing from being formed and splitting
Seam.
About above-mentioned task, it is an object of the present invention to provide the method for realizing ceramic coatings plate, the ceramic coatings
Plate can carry out incrustation acording to the requirement of user, can also realize that " monotone " colours.
Another object of the present invention be easily achieved, general and reliable method, and this method does not need especially
Instrument or equipment, and be therefore easy to industrialize.
Reach above-mentioned task by method as defined in claim 1 and will in the following description more fully
The other purposes occurred；Further feature is defined in following dependent claims.
Specific embodiment
It can be realized the flat sheet made of the enamelled glass ceramic material of surface according to the method for the present invention, that is, table
Area is up to 3m2More than, there is reduceds thickness, be preferably included between about 3mm and 6mm, be more typically in 3mm and 11mm it
Between, it is suitable for cladding flooring board or wall, can both has original size, can also be to be reduced to element with a smaller size.
It is particularly conducive to obtain the glaze plate with single coloring according to the method for the present invention, in entirely prolonging for plate
Stretching is homogeneous in range, and is uniform for all plates for using this method to obtain.However, as detailed below
What ground was explained, using according to the method for the present invention, also can get the glaze plate with incrustation, these incrustations reproduce
Complicated figure, pattern or bossage.
First step a) according to the method for the present invention includes to preset the vitrifying with desired size and thickness
Plate supporter.
Preferably, by toppling over the suitable mixing formed by substantially clay component in the inside of suitable traditional dies
Then object subjects the blend to compacting by the effect of suitable ceramic press and obtains the plate supporter.
Once realizing unfired supporter, then it is subjected to be heat-treated or burn for the first time for the first time at temperature T1
System, temperature T1 are substantially equal to the glass transition temperature TG to form the clay material of supporter, are substantially included in about 1150 DEG C
With 1200 DEG C between to obtain its vitrifying.
It should be noted that in the present specification, when illustrating supporter " vitrifying ", it means that glass is completed in it
Change method, and also have been cooled to environment temperature.
In fact, vitrifying supporter is semi-finished product, it can store and transport as any other ceramic product and is limited
Distance.
For the sake of accurate, it is important that between the pressure initiation step and the first the firing step of unfired supporter,
The latter should not move over long distances, this is because brittleness caused by thickness reduces, in fact uses routine work line, vitrifying support
There is body enough anti-endurance to be transmitted to following operating procedure, especially following surface glazing step b).
Possibly, if necessary, supporter can be made to be subjected to cutting before the step b) of the glazing vitrifying supporter
Step is cut, is suitably cut in cutting step, preferably by using diamond cut head, is followed based on specific requirement
Most suitable geometry and size.
In addition, in the case where expectation provides bigger anti-endurance to the cladding plate obtained at the end of method, especially
When using plate under these conditions, therefore there is significant size, by the netted enhancing structure on the apparent surface of supporter
It is applied to and is advantageous the surface for being subjected to glazing processing in the step b).
Special feature according to the present invention, at least the one of the vitrifying Flat support body obtained during the step a)
A surface portion is subjected to the step b) of glazing, and wherein glaze (that is, substance of liquid or paste or powder type), which uses, has
The ingredient of glass-like surface is formed at a temperature of determining.
Particularly, favorable characteristics according to the present invention apply during glazing step b) according to the method for the present invention
Glaze is selected from such glaze: these glaze have fusible base and metallic pigments, with the vitrifying TG temperature lower than supporter
The glazing temperature TV of degree, and be preferably included between about 600 DEG C and about 900 DEG C, and more particularly in 600 DEG C and 830 DEG C
Between.
After applying the glaze at least one surface portion of the vitrifying Flat support body, it is subjected to hot place
Reason or the firing step c), can obtain the vitrifying for the glaze being placed on its surface.
The firing temperature T2 reached in the step c) be substantially equal to or at least close to above-mentioned glaze glazing temperature
TV, and be therefore preferably included between about 600 DEG C and 900 DEG C, the class of this size based on supporter and used glaze
Type.
Temperature T2 is advantageously enough to obtain the glazing of applied glaze, without changing supporter, because of its glass
Glass, and there is much higher firing temperature under any circumstance.In this way, it is not produced between two kinds of materials advantageously
Raw tension, and the rupture or deformation of plate therefore will not occur, although it with significant size, keeps completely flat
It is smooth.
It is preferable to use suitable single layer roll-type kilns to implement by step c), pays attention to maintaining temperature constant as far as possible.
The glazing step b) available known and conventional various technologies are implemented, these technologies are according to desired on plate
Decorated type selection.For example, using silk-screen printing to obtain the dalle that " monotone " with uniform homogeneous colours
Method is particularly advantageous；In this case, used glaze is preferably paste forms.
Therefore, the different colorings in the decoration for plate can be prepared by mixing the glaze of suitable different colours
(being not present in the market), until obtaining desired tone.
Method for printing screen initially includes preparation particular web, which is included in substantially by external metallization frame
In the frame of formation, applies on the frame and stretch silk lace gauze line to form large-mesh fabric.
Then the silk screen is located on the part on surface of vitrifying supporter to be decorated, and based on to be deposited
The amount for colouring paste, keeps more or less raising relative to supporter.
Then the glaze of paste forms is poured on the fabric of wire frame, and is distributed with scraper in plate to be decorated
On the part on the surface of material；By doing so, can highly uniform and accurate mode glaze is applied with paste with correctly measuring
It is added on the surface to glazing.
On the contrary, obtaining more or less complicated specific decoration creation figure or pattern using method for printing screen in expectation
In the case of, it is necessary to certain colors glaze be not intended to by region in selectively block the mesh of screen fabric, together
When allow glaze penetrate into the region for limiting desired decoration.
For this purpose, suitably applying water-soluble light lotion, then make it dry；Then film of the creation for screening, basic
The front finally decorated is carried in the black background of upper most high-density, and in the side contacted with the surface of plate to be decorated
It is in close contact with the lotion, to make its exposure under ultraviolet light.
Ray only causes following lotion to be hardened in the free space limited by film；On the other hand, with high-density black
The part for the film that color is realized prevents ultraviolet light from passing through, to prevent following lotion from hardening, therefore keeps water-soluble.
The washing of subsequent fabric has the effect of the unhardened lotion of removal, shows the open area of web material, from
And glaze is allowed to lead to the surface below to be decorated with paste forms.
Method for printing screen is further able to obtain the glaze decorating of embossment, without realizing in the material for forming supporter
The embossment or notch that can be obtained with mold in material；In fact, amount and frame by applying lotion on the fabric with it is to be decorated
The effect of the distance between surface, can limit the region that can wherein apply a greater amount of paste forms glaze relative to peripheral region,
To generate bossage relative to bottom.
The step b) of glazing can also be implemented advantageous by spray printing；In this case, glaze is preferably liquid ink
Form, or alternatively use powdered glaze xeroprinting.
It, can also be by using one of method of foregoing description or a variety of methods by glaze based on certain effects to be obtained
Material is applied on the surface of vitrifying supporter.
Finally, in the case where the plate obtained according to the method for the present invention is used to form the cladding on floor, it is used
Glaze, either liquid, powder or paste forms can all be added by determining the powder of the certain material of amount, suitable for making plate
Glazed surface have strong wearability.
In addition, method of the invention can be configured in various embodiments, wherein not only can be according to above-mentioned various modes
It realizes glazing, and can be combined in many ways (including known mode) by various trailings, it is intended to obtain product
Certain effects.
In detail, the present invention may also comprise combines with one or more different glazing mode, is printed using digital ink-jet
The luggage that is deposited into of brush and/or gravel is adornd.
In first version, then the glazing of supporter achievable first continues to decorate using digital printing.
Such as, it can be achieved that monotone glaze coating, and then implementable number before or after glaze method for curing
Decoration, generate nuance effect design or different effects, be included in 600 DEG C with 900 DEG C at a temperature of between after
It is continuous to be fired again.
In fact, it is well known that the decoration carried out by digital printing cannot be in real uniform supporter and big specification
Upper realization monotone background.
Accordingly, with respect to existing knowledge and practice in the industry, the present invention can be realized unavailable at present in surprising mode
Completely new product.
In another embodiment of method of the invention, as non-limiting example, glaze can limit " structure "
Mode is sprawled, and then, before or after glaze method for curing, is continued digital decor using Digital ink jet printing, is being wrapped
It includes and is fired again at a temperature of between 600 DEG C with 900 DEG C.
Herein, " structure " means the decoration using embossment and recess, this, which is implied, is used for this type using lot of materials
The application of type, this can not be obtained using digital printing.
In fact, digital decor makes it possible to be readily available unlimited a variety of two-dimensional decorations, but can not deposit enough
Material generates considerable 3-D effect.
For this reason, Ceramic Corporation is forced to use supporter constructed from the beginning at present, that is, have at
The structure left during shape step.
However, supporter is very expensive, and only could reasonable employment in the case where producing a large amount of finished products.
As previously described, the coating of glaze can be sprawled by using spatula to realize embossment, for being very natural
Effect, or specific pattern or particular texture are obtained by using printing screen.
Digital decor also contributes finished product because of its high accuracy and the diversity of ornament.
In this way, obtain identical or better relative to known system as a result, still there is lower cost simultaneously
And also may customize even for single client, this is not economically feasible for known system.
In another version of the invention, glaze is completed before applying sand grains using grid silk screen and generating bossage
Change.
In another embodiment, glazing is carried out first before applying glass flake.
In addition, method of the invention only can carry out glazing in one or more parts of supporter, then with not
Same method (such as passing through digital printing) decorates other parts；For example, it is contemplated that using digital print methods by gold or other gold
Category is additional to glaze surface, for abundant decoration.
In short, according to the present invention, for obtaining the method with large scale and the glaze cladding plate for reducing thickness, being applicable in
