Description
Technical field
The present invention relates to a kind of scale remover, particularly for the scale remover of concrete pump pipe.
Background technology
All the time, ready mixed concrete must soak pumping line with mortar and lubricate before turn on pump, adopts water and mortar to soak and lubrication piping, to ensure the unobstructed of pumping line.The needed mortar of this method must arrive building site by vehicle transport.In the time that the preparation construction of new building site needs concrete, stirring station all will be sent a concrete delivery truck with charge free and transport mortar toward this building site before pumped and premixed concrete, but inevitably can cause larger waste in transportation.One day needs of a general pump are changed 2～3 building sites, and the supporting transport trolley with mortar will 2～3 train numbers, and this has not only reduced the utilization ratio of concrete delivery truck, has increased transportation cost simultaneously, has cost higher, the shortcoming of waste material.Mortar can only play wetting and lubrication to transport pipe simultaneously, if inner-walls of duct exists concrete dirt, the wetting lubrication that now mortar obviously can not play, appears plugging phenomenon, in the inner concrete dirt of pump line deposition gradually.
In recent years, also having part stirring station to use the agent of profit pipe to add water is lubricated pump line, but this solution had the shortcoming of large fluidity and high glutinous poly-property, if pump line is long, can not fully soak and lubricated pump line concrete (grout congealed solid) dirt simultaneously can not clean-up pump inside pipe wall having adhered to.
Summary of the invention
The object of this invention is to provide a kind of scale remover for concrete pump pipe, this scale remover Castor Oil pump line inwall, while reducing concrete pumping, by the friction resistance of pipeline, guarantee pumping is carried out smoothly, and the grout congealed solid that this scale remover can also adhere to pump line inside is removed.
Technical scheme of the present invention is:
For the scale remover of concrete pump pipe, the weight part of the each component of this scale remover is:
0.1～0.3 part of konjak gum; 1.5～3.0 parts of thickening materials; 0.05～0.15 part of methylcellulose gum; 0.001～0.003 part of sodium lauryl sulphate; 0.3～0.6 part of maltodextrin; 0.05～0.15 part of guar gum; 96～98 parts of limestone powders
Technical scheme is that the weight part of each component is preferably:
0.3 part of konjak gum; 2.0 parts of thickening materials; 0.15 part of methylcellulose gum; 0.002 part of sodium lauryl sulphate; 0.4 part of maltodextrin; 0.15 part of guar gum; 97 parts of limestone powders.
Technical scheme is that the weight part of each component is preferably:
0.25 part of konjak gum; 2.5 parts of thickening materials; 0.10 part of methylcellulose gum; 0.003 part of sodium lauryl sulphate; 0.6 part of maltodextrin; 0.10 part of guar gum; 96.5 parts of limestone powders.
Described thickening material is hydroxypropyl methyl cellulose ether or Xylo-Mucine or cellulose ether.
The water-soluble rear equal energy of melon glue, konjak gum and maltodextrin in the present invention produces a kind of material as a form of gel, is conducive to pump line lubricated, and maltodextrin also has thickening and dispersion to mix the wherein effect of limestone powder simultaneously;
Sodium lauryl sulphate in the present invention is a kind of tensio-active agent, and limestone powder is more easily scattered in solution;
Methylcellulose gum in the present invention has good wettability, dispersiveness, thickening property, water-retentivity and film-forming properties, and institute's film forming has good toughness and flexibility, more easily forms the lubricated film of one deck at inner-walls of duct, makes concrete be easy to pumping.
Scale remover of the present invention can increase its surface tension, increases stickiness, improves bonding strength, increase oilness, in scale remover, limestone powder has surface irregularity, the characteristic that hardness is high and frictional coefficient is large, before ready mixed concrete pumping can to pump truck, the inner-walls of duct of the associated mechanical such as pump transmission be lubricated, pump line inside concrete dirt is cleared up, the phenomenon that prevents plugging occurs simultaneously.Therefore the scale remover of this patent invention, can have the wetting and lubricated effect of pump line, can clear up pump line inside concrete dirt again simultaneously, and the phenomenon that prevents plugging occurs.
The preparation method of scale remover of the present invention is simple, easy to use, can substitute traditional sand-cement slurry completely, have simultaneously environmental protection, nontoxic, tasteless, be easy to decompose, do not affect commerical ready-mixed concrete performance, the advantage such as with low cost.
Konjak gum of the present invention, guar gum, hydroxypropyl methyl cellulose ether or Xylo-Mucine or cellulose ether all adopt commercially available technical grade product;
Maltodextrin adopts the commercially available prod that meets GB/T 20884-2007 " maltodextrin " regulation.
It is fibrous to powder rice shape that methylcellulose gum employing meets appearance off-white, 50～55 DEG C of gelling temps (2% aqueous solution), methoxy content 26%～33%, the commercially available prod that viscosity (20 DEG C, 2% aqueous solution) 15～4000mPa.s requires.
Sodium lauryl sulphate adopts sodium lauryl sulphate K12 to meet the commercially available prod of GB/T 15963-2008 quality standard
.
Limestone powder adopts CaCO
3the commercially available prod that content is greater than 85%, taking this Wingdale product as raw material, it is the flour of 350 ㎡/kg-500 ㎡/kg that grinding becomes specific surface area.
The unit of weight part of the present invention is g or Kg.
Embodiment
Embodiment 1
The mass percent of each material component is konjak gum 0.3Kg, thickening material 2.0Kg, methylcellulose gum 0.15Kg, sodium lauryl sulphate (K12) 0.002Kg, maltodextrin 0.4Kg, guar gum 0.15Kg, limestone powder 97Kg.
Example 2:
The mass percent of each material component is: konjak gum 0.25Kg, thickening material 2.5Kg, methylcellulose gum 0.10Kg, sodium lauryl sulphate (K12) 0.003Kg, maltodextrin 0.6Kg, guar gum 0.10Kg, limestone powder 96.5Kg.
Get each material according to the proportioning described in embodiment 1 or 2, adopt direct mixing method to mix in dry-mixed mortar mixer, obtain the scale remover for concrete pump pipe of the present invention.
While using concrete pump pump concrete, for preventing leaving resistates in pump line, should the enough water cleaning pipelines of first pumping, until hopper in and ducted water start to manage by scale remover profit after fanning the air., in the container that water is housed, need to add above-mentioned scale remover when the working-yard, start electric mixer and stir, stir at least 5 minutes, after water can fully be mixed with scale remover, pumping, with scale remover profit pipe.After profit pipe, scale remover is discharged to construction formwork.
When scale removal, every 50 meters of length pump lines use scale remover 25kg of the present invention, and 50 meters of less thaies are by 50 meters of calculations.When use, directly add water, the 15-20 that the weight adding water is scale remover doubly, stirs and is uniformly dispersed and can be pumped into pipeline and soaks scale removal to product for 5-8 minute.The external diameter of described pump line is 150mm.
Scale remover of the present invention only, for concrete pump and the wetting scale removal of pipeline, after scale removal, need be discharged construction formwork by pipeline, must not enter construction part.
Applicant was by the construction experiment of nearly a year, building of the construction part such as pile foundation, floor slab column, oblique roofing, beam slab, road, tower crane, slab column, garage, pile foundation, before construction, all with scale remover of the present invention, pump line is moistened to pipe and scale removal, pumping concrete construction again, all do not occur that result of use is good because of the problem of the not good plugging booster causing of profit pipe descale effect.When use, actual amount is according to pumping line distance, and every 50 meters use 1 bag (25 kilograms) to be watered 400-450kg to use, and 50 meters of less thaies are by 50 meters.
Explanation of nouns: pumping---send to through pipeline by concrete pump.
