Background technology
Modern society, the moulding of buildings is increasingly various, function is also day by day perfect, high-tech is applied to building field more and more, each product is all the research and development point of self product with meeting the market requirement, nature, elegance, tool personality elements is more and more tending towards till now from early stage ornamental decorative effect, and the market requirement needing durable, environmental protection, grow with each passing hour.
Ceramic is high, various in style with its strong adaptability, density, pattern enriches, good decorating effect, easily to maintain, when it is applied to suitable environment, due to reaching its maturity of production technology, also more and more access expansion is true to nature for the pattern of product, so deeply by consumers.
The ceramic tile that the existing whiteness in market is high, its white color, glossiness are high, are subject to the favor of certain customers, but because its raw-material selection is generally all in south, material cost is high, and selection region is little, ceramic tile top layer and base substrate whiteness inconsistent, higher radiativity, need two layers of cloth, cause the post-production performance of extreme difference, price is high, a client group of mean people, the scope of application is little.
The each enterprise all the time continuous ceramic tile new technology high to whiteness is studied, try hard to exploitation performance more superior, radioactivity is low, good decorating effect, texture, didirtresistance, wear resistance parameter are all excellent, the ceramic tile that cost is low, the novel whiteness of long service life is high.
Summary of the invention
The object of the invention is to overcome northern China cannot utilize local starting material to manufacture the present situation of the high ceramic tile of whiteness, all use local starting material first, manufacture that a kind of exquisite in texture, whiteness are high, good decorating effect and compact and uniform structure, radioactivity are low, antifouling property good, easy maintenance, protection against the tide, energy-conserving and environment-protective, ceramic tile that cost entire body whiteness that is low, long service life is high.
The object of the invention is to be achieved through the following technical solutions:
The ceramic tile that entire body whiteness is high, the weight percent of described ceramic tile main raw material is: feldspar 15 ~ 30%, quartzite 20 ~ 35%, white sand rock 10 ~ 35%, kaolin 13 ~ 25%, clay 2 ~ 5%;
The mass percent of the chemical constitution of described ceramic tile main raw material is: SiO
252.03 ~ 72.52%, Al
2o
33.55 ~ 15.25%, Fe
2o
31.50 ~ 3.50%, TiO
20.12 ~ 1.98%, CaO3.05 ~ 9.50%, MgO1.15 ~ 6.50%, K
2o0.07 ~ 4.34%, Na
2o0.16 ~ 7.1%;
By above-mentioned starting material by following process steps: the purchasing of raw materials → raw material screening → formula formulates → batching ball milling → slurry → slurry is old → and the deironing → spraying dry → powder → powder that sieves is old → dispensing powder → cloth → compression moulding → drying → burn till → edging → classification → packaging → warehouse-in, make the ceramic tile that entire body whiteness is high.
Powder particles degree weight percent after spray-dried processing step is: 20 ~ 40 mesh screen residues: 0.5 ~ 27.1%; 60 ~ 80 mesh screen residues: 28 ~ 48.6%; 80 ~ 100 mesh screen residues: 10.4 ~ 27%; 100 mesh screen residues: 1.8 ~ 5.9%.
Blank forming pressure after distributing technique step: >=260Mpa.
Blank forming frequency after distributing technique step: 3.5 ~ 4.2 beats/min.
Through kiln drying temperature: 180 ~ 230 DEG C.
Through kiln drying cycle: 60 ~ 90min.
Firing temperature in described firing process step: 1170 ~ 1210 DEG C.
The quench zone temperature of firing temperature in described firing process step: 1100 ~ 600 DEG C.
Firing period in described firing process step: 60 ~ 90min.
The present invention adopts technique scheme can reach following beneficial effect:
1, creative.The present invention all introduces the high ceramic tile of northern local starting material production entire body whiteness first, and ceramic tile top layer is consistent with base substrate whiteness, good decorating effect, finds no identical product temporarily occur at ceramic field.
2, energy-conserving and environment-protective.The present invention utilizes northern local starting material: feldspar, quartzite, white sand rock, kaolin, clay is as main raw material(s), overcome ceramic tile starting material in prior art can only to have drawn from south, need secondary material distributing, ceramic tile top layer and the inconsistent defect of base substrate whiteness, only need a cloth, namely top grade is produced, entire body whiteness is high, and the ceramic tile that top layer is consistent with base substrate whiteness, product radioactivity is far below the common ceramic tile in market, and can low temperature fast firing, both the effect of beautifying the environment had been reached, reach again the object reducing the wasting of resources, comply with national energy-saving to reduce discharging, the requirement of environmental protection.
3, easily maintain.Body recipe of the present invention, the anti-wear-resisting and stain resistance on brick surface is higher, in use low water suction, anti-excellent wear resistance, anti-aging, more easy cleaning and maintenance, and corrosion-resistant.
4, good decorating effect.The present invention breaks through the production technique of the high ceramic tile of traditional whiteness, and organically combined by formula technique technique by the ceramic raw materials such as local for north feldspar, white sand rock and kaolin, ceramic tile entire body whiteness is high, and texture is strong, and clean mark is smooth, good decorating effect.Radioactivity: interior according to Ira≤0.5; Outer according to Ir≤0.9.
5, good product performance, folding strength superelevation.The ceramic tile energy index that the more common whiteness of the present invention is high is better: product water-intake rate is less than 0.08%, product more than folding strength 45Mpa.
6, durable.Stable performance of the present invention, less by time, environmental influence, can keep for a long time as new sensation, long service life, there is wide market economy benefit.
7, use range is wide.The present invention by suitable environment conditionality, does not overcome the problem that the high ceramic tile radioactivity of common whiteness is high completely, can be widely used in various inner-outer wall and ground decoration.
8, quality densification, entire body ultrawhite, post-production performance are good.The present invention adopts most advanced and sophisticated firing process to produce, high-compactness, interiors of products close structure, indeformable, do not ftracture, not frangibility, and stable performance, environmental protection, radiationless, do not corrode by various material, owing to being that entire body whiteness is consistent, being applied to down big angle, to open the post-production such as vat completely unaffected.
9, market economy benefit and social benefit wide.The starting material of the present invention owing to using the north local completely, the cost advantage himself had can adapt to the demand of society, and the ceramic tile output value that the anticipations of profit are higher than common whiteness increases about 30 ~ 50%, and market economy effect is wide; While generation good economic benefits, the local starting material of Appropriate application, low temperature fast firing, the waste discharge of minimizing, can reach good social benefit.
