Abstract
The invention discloses a microcrystal dry grain adhering agent which comprises the following components in percentage by mass of 2.7-3.6 percent of alkali swelling type thickening agent, 1.2-1.8 percent of bentonite and 1.4-2.7 percent of assistant, a pH regulating agent for regulating the pH of a system to be 8.0-9.0, and the balance of solvent. During use, microcrystal dry grains are uniformly mixed with microcrystal dry grain adhering agent and then the mixture is applied to the surface of a blank body. The microcrystal dry grain adhering agent disclosed by the invention is suitable for microcrystal dry grains with a grain size of 100-250 meshes; in a process of preparing a microcrystal brick, the microcrystal dry grains are prevented from being taken away by low negative pressure of a preheating band of a kiln if the microcrystal dry grains are too small in grain size, therefore, flaws such as a large quantity of pinholes and bubbles in the surface of the microcrystal brink are avoided. After being mixed with the adhering agent provided by the invention, the microcrystal dry grains are good in suspension property, stability and flowability, do not easily precipitate, and cannot generate bubbles after being continuously used.
Description
Technical field
The invention belongs to architectural ceramic industry, be specifically related to a kind of crystallite dry granular caking agent.
Background technology
Crystallite brick is the crystallite composite brick of a kind of alternative stone material of ceramic industry development in recent years, the flaw that it has not only avoided lithotome to exist, and integrate glass, pottery, stone material advantage, compact product structure, clean mark, glittering and translucent, stereoscopic sensation is strong, has the sensation as beautiful matter.Crystallite brick is that after polished finish, the lines of stone material is life-like at the thick transparent layer of surface decoration 2～5 mm of general Antique Imitation Tiles, and specular brightness reaches 95 to 97, has reappeared a kind of as beautiful in the gentle effect as amber.At present, crystallite brick is mainly by cloth system, on glaze upper berth, to cover certain thickness dry granular (size of dry granular is at 20～100 orders), and spray one deck fixing agent dry granular is being fixed on to billet surface, burn till and rear glaze is carried out to polishing, the quality of dry granular has directly determined the quality of crystallite brick decorative effect, in production, too little particle is easily introduced pin hole and bubble when burning till, what is more important fine particle (particle diameter is not more than 100 orders) due to lighter weight easily in the preheating zone of kiln because lower negative pressure is sucked away.
Along with the crystallite dry granular of various decorative effects arises at the historic moment, its market of bringing is also inestimable.But the processing of dry granular adopts impact grinding at present, dry granular is directly fallen into the rotating disk of high speed rotating by machine top, under the effect of high speed centrifugation power, shunt at the target stone of rotating disk surrounding and produce high-speed shock and highdensity pulverizing in umbellate form mode with another part, building stones are after hitting mutually, can between rotating disk and casing, form vortex motion again and cause mutual strike, friction, pulverizing repeatedly, the straight-through discharge from bottom.This processing mode has produced part cannot adapt to the small dry granular (particle diameter is not more than 100 orders) of existing cloth system, thereby has caused the wasting of resources.Common small dry granular (particle diameter is not more than 100 orders) is difficult to directly be fixed on the surface of base substrate, is therefore difficult to directly be applied.If by adding caking agent again to drench the mode of glaze in dry granular, can realize the surface that small dry granular is fixed on equably to base substrate, thereby reach good application.So, be badly in need of a kind of dry granular caking agent of research and connect small dry granular, adopt modes such as drenching glaze that small dry granular is applied to actual production, thereby turn waste into wealth, both can reduce the waste of resource, can bring considerable economic benefit for enterprise again.
Glaze pouring requires to add crystallite dry granular to mix afterwards flow velocity with caking agent and, lower than 50s(30 ℃, is coated with-4 glasss), and can not precipitate, the solid content of crystallite dry granular is higher than 60%, but this to be common glue or caking agent be difficult to realization.The domestic research to crystallite dry granular caking agent is at present fewer, and the rare product occurring on market also presents various limitation.So work out, add good fluidity after crystallite dry granular, suspension excellence and the high caking agent of solid holdup to there are wide market outlook.
Summary of the invention
The object of the present invention is to provide a kind of crystallite dry granular caking agent.
For existing deficiency in prior art, the technical solution adopted in the present invention is:
