Description

A method of potsherd is prepared using cinder
Technical field
The present invention relates to potsherd technical fields, and in particular to a method of potsherd is prepared using cinder.
Background technique
Ceramic industry development in recent years is swift and violent, and the demand to raw material is also increasing.It is well known that mineral resources are Non-renewable resources, most of Ceramics Enterprises all ceramic body whiteness in the continuous improvement, improve the market competition of itself product Power, but good raw material is reduced increasingly, and quality is also not equal to before；In addition, prices of raw materials rise directly results in enterprise Production cost jumps up.Therefore, new raw material is developed, production cost is reduced, improving product quality is current ceramic industry One new research direction.
Cinder is one kind of solid waste, and yield is larger, and about 0.35 ton of cinder is averagely generated after 1 ton of coal combustion.Cinder It throws aside, occupies tract, sulfide, which is escaped or leached, can pollute atmosphere, farmland, water body, natural fire also easy to happen, Long-term stack brings very big harm to ecological environment.With the development of society, the raising of environmental requirement, resource, the energy The comprehensive utilization of minimizing, waste is particularly important, and waste wtility had not only protected environment but also increased resource regeneration, make through Ji is improved with context synchronization.Contain a large amount of SiO in cinder2、Al2O3、Fe2O3, CaO, there are also a small amount of remaining calorific value, therefore, Application of the research recycling cinder in ceramic tile body recipe, not only reduces the consumption of traditional raw material, and can be more Waste material cinder is preferably utilized, the recycling of waste material is realized, not only improves save the cost, and be conducive to environmental protection.
The appearance color of cinder is yellow, lime color, light/dark balance, main component SiO2: 45-55%, Al2O3: 30-36%, Fe2O3: 5-11%, CaO:9-15%, it is that a kind of particle is thicker that it is corvinus that briquette examination, which is made, and burns, residue complex in composition Material, containing plurality of impurities, such as using cinder production Ceramic Tiles, there are some insoluble technical problems, so as to cause in reality It is dfficult to apply to Ceramic Tiles in production, is primarily present following urgent problem to be solved: (1) cinder recycling being used into tile green body In formula, since cinder contains a large amount of black impurity (iron content is high), impurity composition is more and complicated, and firing temperature is low, Yi Fasheng Reaction expansion, easily influence product quality, are mainly manifested in green body and stain occur, fusion hole, so as to cause glaze pin hole, fusion hole, The ceramics defect such as spot, bulge；(2) generation of cinder is more mixed and disorderly, keeps cinder performance unstable；(3) cinder is easy in mud Precipitating, suspension is poor, therefore need to solve the performance of cinder mud, makes it to be sufficiently mixed uniformly with ceramic mud.
Summary of the invention
It is an object of the invention to aiming at the shortcomings in the prior art, and provide a kind of side that potsherd is prepared using cinder Method, this method introduce cinder as blank raw material, improve the performance of cinder mud, solve due to introducing cinder and cause There is the problem of ceramics defect such as pin hole, fusion hole, spot, bulge in glaze, so that the properties of green body is not affected, guarantees life The stability of production.
