Abstract
The invention relates to a method for producing a recrystallized ceramic product by utilizing waste ceramic. The method comprises the following steps: selecting and washing the waste ceramic products; breaking the washed waste ceramic products to obtain waste ceramic powder with a particle size less than 6mm; reserving powdered quartz, feldspar, washed kaolin and clay; preparing the materials of the recrystallized ceramic product in parts by weight: 50 to 97 parts of waste ceramic powder, 0 to 30 parts of quartz, 0 to 30 parts of feldspar, 3 to 40 parts of clay, 1 to 30 parts of kaolin, 0 to 15 parts of binding agent and 0.2 to 0.4 part of water reducing agent; grinding the materials in a ball mill with water, wherein the weight ratio of the material to a ball to the water is 1: 1.5: 2; carrying out wet ball milling on the materials to obtain a slurry; preparing a green body by adopting the slurry according to a conventional process flow and a conventional forming method, and burning the green body to form ceramic. According to the method, the waste ceramic is used as a main raw material, the material cost is low, and the enterprise benefit is high. The intrinsic quality of the product is stable, the quality is good, the resource and environment are protected, waste is changed into treasure, and the new way is developed for developing the waste ceramic.
Description
Technical field
The present invention relates to a kind of production method of ceramic product, particularly relate to a kind of method of producing recrystallized ceramic with waste and old porcelain.
Background technology
At present, according to the display of relevant data statistics, China's ceramic yield ranks first in the world, and accounts for 40%-45% of the every annual amount in the world, wherein; Household china output is 200,000,000, sanitary china output is 1.4 hundred million, floor tile output is 400,000,000 square metres, Production of Ceramics raw material used is silicate minerals, and silicate minerals belongs to disposable resource, and is Nonrenewable resources, this just causes the high quality raw material needed for ceramic raw material production increasingly exhausted, meanwhile, Production of Ceramics process is complicated, robotic degree is low, its scrap rate about about 10%-25%.And abandoning of shabby ceramic article is also an objective quantity in daily life.Due to waste old ceramics non-degradable, they not only occupy large stretch of arable land, go back serious environment pollution.
As ceramic making, traditional ceramics kind has, feldspathic pottery; Adopt " feldspar--quartz--kaolin " to be main three components batching.Sericite china: general advanced age and porcelain stone two component of adopting is prepared burden.Magnesia steatite ceramic: main raw material has talcum, clay, feldspar three kinds.Bone China contains the calcium phosphate of a great deal of, usually introduces the Ceramic Art Design theories such as calcium phosphate with animal bone ash.Be familiar with to some extent by people gradually the utilization of waste old ceramics in recent years, and had and quote useless porcelain report, the method in these reports is just as improving base glaze physicochemical property, and the amount of quoting is considerably less.Such as Chinese patent CN1205148C discloses one and " utilizes the method for useless porcelain and obtained porcelain mud thereof ", its weak point of the method is, in base substrate pug formula, introducing portion is given up porcelain, other or ceramic raw material, like this at sintering procedure crystalline formation imperfection, product stability is poor, very easily occurs defective goods.Meanwhile, fail to reach and make full use of waste old ceramics object.Use value is lower.
goal of the invention
In order to solve the deficiencies in the prior art, the invention provides a kind of method of producing recrystallized ceramic goods with waste and old porcelain, the method take waste old ceramics as main raw material, only add a small amount of ceramic raw material and regulate use as physicals, the useless crystalline phase of porcelain own physically well develops, recrystallization makes it more perfect, and product stability is good, solves traditional ceramics products production, a ceramic difficult problem that use, preservation burst.Meanwhile, open resource, has administered environment, becomes useless porcelain into precious, greatly reduces production cost, ceramic cycles is used, realize persistence Economic development.
Realize above-mentioned purpose by the following technical solutions:
Produce a method for recrystallized ceramic goods with waste and old porcelain, it is characterized in that, described method comprises the steps:
A. waste old ceramics goods are carried out selecting cleaning;
B. broken in being carried out by the waste old ceramics goods after cleaning, the particle obtaining particle diameter <6mm is that useless porcelain powder is for subsequent use;
C. the kaolin of flint, feldspar and elutriation, clay is for subsequent use;
D. the material of following portions by weight is configured: the component and the parts by weight that form recrystallized ceramic goods are: useless porcelain powder 50-97, quartzy 0-30, feldspar 0-30, clay 3-40, kaolin 1-30, bonding agent 0-15, water reducer 0.2-0.4;
E. above-mentioned material is entered ball mill to add water grinding, the weight ratio of material, ball, water is 1:1.5:2, and wet ball grinding obtains the mud of particle fineness 0.15-0.3g/500ml;
F. by mud conveniently technical process and forming method make base substrate, be fired into porcelain.
As preferably, according to weighing scale, useless porcelain introduction volume > 50%.
As preferably, the component and the parts by weight that form recrystallized ceramic goods are: useless porcelain powder 90, quartz 2, kaolin 1, clay 4, bonding agent 2.625, water reducer 0.375.
As preferably, described water reducer is sodium carbonate or Starso.
As preferably, described conventional flowsheet make ceramic methods plastic making and slip casting method shaping.
Adopt technique scheme, the present invention is main material production ceramic with waste old ceramics, solves the problem that in prior art, waste old ceramics consumption is low.Having broken in traditional ceramics production technique with clay is main plastic raw material, non-plastic raw material only accounts for a part to meet moulding process requirement, the present invention expects (can reach 97%) with poor material (waste old ceramics) for main, add a small amount of raw material and bonding agent to meet shaping processing requirement, obtained product reaches national ceramic standard after testing.Due to the present invention with useless porcelain for main raw material, the cost that feeds intake reduce the performance of enterprises high.Not only make it nondegradable waste and old porcelain to obtain again to follow and also use, product inherence is stable, and quality is good, meanwhile, protects resource and environment, and useless porcelain is fully used, and has really accomplished to turn waste into wealth, and opens the new way that useless porcelain utilizes.
