Description
Technical field
The present invention relates to a kind of ball clay that can be used as super-white polished ceramic tile raw material, the invention still further relates to the production method of this ball clay.
Background technology
Along with improving constantly of standard of living, people are also more and more higher to decorate requiring, and quality and whiteness to the ceramic tile that adopts when decorating are also more and more fastidious.The pottery manufacturing is made great efforts the super-white polished ceramic tile of development, and the raw material that present ceramic manufacturing adopted, spend (this whiteness is the whiteness of formulating among the CNS QB/T1503-1992 " domestic ceramics whiteness test method ") and process industrial art performance and other well behaved ball clay if lack greater than 80, just can't produce super-white polished ceramic tile in batches through whiteness behind 1180 ℃ of high-temperature calcinations.Therefore, because the cause of raw material, ceramic manufacturing enterprises is difficult to produce not only to have high-qualityly, simultaneously but also the ceramic product with high whiteness, makes the quality product of ceramic manufacturing enterprises be difficult to reach a new platform, thereby is difficult to satisfy the requirement of Modern Decorative industry to the ceramic product whiteness.
Summary of the invention
In order to overcome the deficiencies in the prior art, one object of the present invention is exactly that a kind of ball clay of producing the required whiteness behind 1180 ℃ high-temperature calcination of super-white polished ceramic tile greater than 80 degree will be provided.
Another object of the present invention is exactly the production method that a kind of this ball clay will be provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of ball clay as super-white polished ceramic tile raw material, this ball clay includes following raw material: kaolin, secondary clay, water, thinner and flocculation agent; In the ball clay gross weight, wherein: kaolin content is 14～63%; Secondary clay content is 7～56%; The content of thinner is 0.01～2%, and the content of flocculation agent is 0.01～1%, and water is 22～32%.
Above-mentioned thinner preferably adopts water glass, tripoly phosphate sodium STPP (Na
5P
3O
10) or Sodium hexametaphosphate 99 [(NaPO
3)
6] or its mixture, wherein water glass preferably.
Above-mentioned flocculation agent preferably adopts magnesium chloride, calcium chloride or nitric acid, wherein the mixture of magnesium chloride or calcium chloride and nitric acid preferably.
The material that occurring in nature can be used as the production ceramic raw material is a lot, and kaolin and secondary clay are exactly wherein two kinds.To be aluminosilicate rocks such as feldspar, sericite collapse the clay that left behind on the spot after broken through weathering to kaolin, the soluble substance that is produced in efflorescence is taken away with the rainwater erosion, stay kaolinite and quartz, therefore its quality is purer, ceramic raw material burning back whiteness with its production is higher, but because its particle is thicker, so plasticity-is relatively poor, and intensity is less.
And secondary clay is the drift through rainwater, rivers and creeks of the primary clay that formed by weathering, the migration of wind-force and the clay that forms in low-lying place deposition, attenuate through the collision friction at drift transition process medium clay soil itself, be entrained into some organic substances and other impurity simultaneously, therefore secondary clay has that particle is tiny, plasticity-is strong, intensity is than characteristics such as height, and it is relatively poor to burn the back whiteness with the ceramic raw material of its production.
The principal element that influences product whiteness in the production process of pottery is ferric oxide and the titanium oxide content in the raw material, the content height of ferric oxide and titanium oxide in ceramic raw material, and the whiteness of the ceramic product of being produced after the calcination is just low; The content of ferric oxide and titanium oxide is low in the ceramic raw material, and the whiteness of the ceramic product of being produced after the calcination is just high.But, when adopting the low ceramic raw material of ferric oxide and titanium oxide content, burn the back whiteness, the corresponding reduction of process industrial art performances such as the plasticity-of ceramic batch and normal temperature bending strength and have a strong impact on production though can improve ceramic product.
Based on above-mentioned principle, whiteness and normal temperature bending strength and process industrial art performance are to oppose mutually after the burning of ceramic raw material, and this contradiction has seriously restricted the development of ceramic manufacturing enterprises.
For addressing the above problem, the inventor passes through long-term exploration, adopt kaolin and secondary clay, pass through scientific formula, and the employing advanced technologies, reduced the content of ferric oxide and titanium oxide in the ball clay, improved whiteness after the burning of raw material, and efficiently solve in the ceramic manufacturing enterprises ubiquitous ceramic raw material when improving it and burning back whiteness, the problem that normal temperature bending strength and other processing characteristics descend thereupon.
The physicochemical property of the ball clay as super-white polished ceramic tile raw material of the present invention sees Table 1.
