Abstract
The invention discloses a manufacture process for producing high-quality ceramic glazes by aid of waste ceramics. The manufacture process includes the following production steps: taking sodium carbonate, quartz stone and albite for mixing, ball milling and roasting to be processed to be particles with diameters smaller than 1mm, and making the particles into roasted frits; taking waste ceramics, roasted potash feldspar, roasted quartz stone and roasted frits for mixing and ball milling to be with fineness above 380 meshes and made into powder materials; taking the powder materials, methylcellulose and clean water for mixing and stirring to be made into dispersing solution and preparing the ceramic glazes. According to the manufacture process, roasted potash feldspar, roasted quartz stone and roasted frits are adopted so that problems caused by massive waste ceramics adding are solved, and the technical forbidden zone in the ceramic industry of adding massive waste ceramics according to the ceramic glaze production formula and taking waste ceramics as main materials is broken through.
Description
Technical field
The present invention relates to ceramic field, particularly a kind of manufacture craft of utilizing waste ceramic production high-quality enamel.
Background technology
In the products production of ceramic industry, because product percent of pass can not reach 100% in producing, particularly in the product sintering process, produce scrap products inevitably, this scrap products is called waste ceramic.Because waste ceramic is the temperature calcining through 1100～1370 ℃, formed the crystallisate of mullite, chemicalstability is high, in physical environment, is difficult to degraded, as being buried or abandoning, then becomes environmental pollution.Recognizing the characteristics of waste ceramic, particularly through calcining and become the characteristics of crystallisate, can it be used in the Production of Ceramics, is a contribution greatly of recycling economy aspect, has society and economic double benefit.
Because the restriction of technology, in the production pug of ceramic industry (particularly domestic ceramics, the art pottery, snitaryware), the ratio that adds useless porcelain has only 10%～30% at present, and the discrete art pottery has only below 45% with the useless porcelain add-on of mud.And the add-on of enamel aspect has only percentum, and the porcelain that just will give up can not be as main raw as additive.
Can be with the main raw of porcelain that give up, and make the enamel of processing adapt to the course of processing of product glazing as enamel, and the high-quality more of the glaze layer after product is burnt till, be the problem of studying in the ceramic industry.
Summary of the invention
For addressing the above problem, the present invention provides a kind of manufacture craft of utilizing waste ceramic production high-quality enamel, and this enamel prescription is to be main raw material with useless porcelain; The enamel of processing is used in the products production; Can make the product glaze more closely knit, defectives such as glaze layer pore reduce, and product percent of pass improves.
The manufacture craft of utilizing waste ceramic production high-quality enamel of the present invention comprises following production stage:
(1) gets yellow soda ash 23～25%, quartzite 47～49%, albite 27～29% by weight percentage; Carry out ball milling after three's raw materials mix; Cross 200 mesh sieves to fineness; Then in 1200 ℃～1220 ℃ the calcining 6～8 hours after, with calcine handle to diameter less than the 1mm particle, process the calcining frit;
(2) get by weight percentage and carry out ball milling to fineness after useless porcelain 65～70%, calcining potassium felspar sand 15～20%, calcining quartz stone 6～8%, calcining frit 6～8% mix and cross 380 mesh sieves, process powder;
Said useless porcelain is to select for use through the useless porcelain of the lily household china that burns till more than 1330 ℃, and useless porcelain is smashed to the particle of diameter less than 1mm; Said calcining potassium felspar sand is that potassium felspar sand, after 8～10 hours is handled calcine to the particle of diameter less than 1mm through 1250 ℃～1280 ℃ calcinings; Said calcining quartz stone is that quartzite, after 8～10 hours is handled calcine to the particle of diameter less than 1mm through 1250 ℃～1280 ℃ calcinings;
(3) get powder 48～52%, methylcellulose gum 4～6%, clear water 44～46% by weight percentage, the three is mixed into dispersion liquid, processes enamel of the present invention.
For ease of understanding the present invention, the method for use of simple declaration enamel of the present invention.Method with enamel of the present invention is produced domestic ceramic product comprises following production stage:
(1) processes ceramic molded product (being commonly called as unpainted clay idol) by common process;
(2) with the 1150 ℃ of biscuitings (being commonly called as sintering) of ceramic molded product warp, sintering time is 8～10 hours;
(3) sintered products employing hand soaks glazing or the glaze spraying mode is carried out glazing to passing through;
(4) the glazing product being sent into kiln, to carry out temperature be that 1330～1350 ℃, time are 8～10 hours burning till, and makes domestic ceramic product.
Glaze glossiness through burning till domestic ceramic product is good, and glaze is closely knit, and whiteness reaches 80%, and glaze can not see pore under the naked eyes situation.
In traditional enamel, the deal of calcine (promptly being crystallisate) is less, the non-calcine of adding (like kaolin etc.) in burning till, producing volatile matter, these volatile matters break through the glaze layer, make the glaze layer produce defectives such as pore.
In prescription of the present invention, useless porcelain accounts for maximum ratio.Because useless porcelain is a calcine (crystallisate) completely, and other composition is calcine basically.Volatile matter in the mineral material decomposes volatilization in a large number in calcining, the enamel that adopts crystallisate to process is a kind of highly purified crystalline glaze, is applied to ceramic product after burning till, and the product glaze then has the fine effect.And adopt useless porcelain can remove calcination process from, and utilized waste again, greatly reduce production cost.
For solving a large amount of porcelain that give up that add in the enamel, cause series mass problems such as glaze loss of gloss.The present invention adopts calcining potassium felspar sand, calcining quartz stone, calcining frit, has solved the useless caused problem of porcelain of a large amount of addings, has broken through in the ceramic industry, and the useless porcelain of a large amount of addings in the enamel production formula is with the technological forbidden zone of useless porcelain as main raw.
