Background technology
Modern society, the moulding of building is increasingly various, and function is also increasingly perfect, and high-tech is increasingly being applied to
Building field, each product is to meet the market requirement as the research and development point of itself product, from the ornamental decorative effect of early stage till now
Increasingly tend to nature, elegance, tool personality elements, and need the market demand that is durable, environmentally friendly, growing with each passing hour.
Ceramic is with its strong adaptability, consistency is high, various in style, pattern enriches, good decorating effect, easily maintenance, its
During applied to suitable environment, due to reaching its maturity for production technology, it is true to nature that the pattern of product also becomes closer to nature, so deep
It is popular with consumers.
The high ceramic tile of the existing whiteness in market, its white color, glossiness are high, are favored by certain customers, but because of it
The selection of raw material is generally in south, and material cost is high, and selection region is small, and ceramic tile top layer and base substrate whiteness are 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, and the scope of application is small.
Each enterprise ceramic tile new technology all the time constantly high to whiteness is studied, try hard to develop performance it is more superior, put
Penetrating property is low, good decorating effect, texture, soil resistance, wearability parameter are excellent, and cost is low, the new whiteness of service life length is high
Ceramic tile.
The content of the invention
It is an object of the invention to overcome northern China can not utilize the present situation of the high ceramic tile of local raw material manufacture whiteness,
All manufacture high a kind of exquisite in texture, whiteness, good decorating effect and compact and uniform structure using local raw material first, put
Penetrating property is low, antifouling property is good, easy maintenance, protection against the tide, the ceramic tile that energy-conserving and environment-protective, cost are low, the entire body whiteness of service life length is high.
The purpose of the present invention is achieved through the following technical solutions:
A kind of high ceramic tile of entire body whiteness, the percentage by weight of the ceramic tile primary raw material are:Feldspar 15~30%, stone
English rock 20~35%, white sand rock 10~35%, kaolin 13~25%, clay 2~5%;
The mass percent of the chemical composition of the ceramic tile primary raw material is:SiO252.03~72.52%, Al2O3
3.55~15.25%, Fe2O31.50~3.50%, TiO20.12~1.98%, CaO 3.05~9.50%, MgO 1.15~
6.50%, K2O 0.07~4.34%, Na2O 0.16~7.1%;
Above-mentioned raw material are pressed into following process steps:The purchasing of raw materials → raw material screening → formula formulation → dispensing ball milling → slurry
Material → slurry is old → sieving iron removaling → spray drying → powder → powder is old → dispatching powder → cloth → compressing →
→ edging → classification → packaging → storage dry → is burnt till, the high ceramic tile of entire body whiteness is made.
Powder particles degree percentage by weight 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.
By kiln drying temperature:180~230 DEG C.
By kiln arid cycle:60~90min.
Firing temperature in the firing process step:1170~1210 DEG C.
The quench zone temperature of firing temperature in the firing process step:1100~600 DEG C.
Firing period in the firing process step:60~90min.
The present invention can reach following beneficial effect using above-mentioned technical proposal:
1st, it is creative.The present invention is fully incorporated the high ceramic tile of the local raw material production entire body whiteness in the north, ceramic tile table first
Layer, good decorating effect consistent with base substrate whiteness, temporarily find no identical product in ceramic field and occur.
2nd, energy-conserving and environment-protective.The present invention is to utilize the local raw material in the north:Feldspar, quartzite, white sand rock, kaolin, clay
As main raw material(s), overcoming ceramic tile raw material in the prior art can only have drawn from south, need secondary material distributing, ceramic tile top layer with
The defects of base substrate whiteness is inconsistent, a cloth is only needed, that is, produce high-grade, entire body whiteness height, and top layer and base substrate whiteness one
The ceramic tile of cause, product radioactivity are far below the common ceramic tile in market, and can low temperature fast firing, both have the function that to beautify the environment, again
Reach the purpose for reducing the wasting of resources, comply with national energy-saving emission reduction, green requirement.
3rd, easily maintenance.The body recipe of the present invention, the anti-wear-resisting and stain resistance on brick surface is higher, in use
It is low water suction, anti-excellent wear resistance, anti-aging, it is easier to cleaning and maintenance, and it is corrosion-resistant.
4th, good decorating effect.The present invention breaks through the production technology of the high ceramic tile of traditional whiteness, by the local feldspar in the north, white sand
Rock is organically combined with ceramic raw materials such as kaolin by formula technique technique, and ceramic tile entire body whiteness is high, and texture is strong, clean mark stream
Freely, good decorating effect.Radioactivity:It is interior to shine Ira≤0.5;It is outer to shine Ir≤0.9.
5th, good product performance, rupture strength superelevation.The high ceramic tile energy index of the more common whiteness of the present invention is more preferably:Product absorbs water
Rate is less than 0.08%, more than product rupture strength 45Mpa.
6th, durable.Stable performance of the present invention, it is smaller by time, environmental influence, it can keep feeling as new for a long time,
Service life is grown, and has wide market economy benefit.
7th, use range is wide.The present invention overcomes the high ceramic tile of common whiteness and put completely not by suitable environment conditionality
The problem of penetrating property is high, it can be widely applied to various inner-outer walls and ground decoration.
8th, quality densification, entire body ultrawhite, post-production performance are good.The present invention is produced using sophisticated firing process, high fine and close
Degree, interiors of products close structure is indeformable, do not ftracture, be not easily broken, and stable performance, environmentally friendly, radiationless, not by various things
Matter is corroded, and due to being that entire body whiteness is consistent, applied to big angle, is opened the post-productions such as vat and is entirely unaffected by.
9th, market economy benefit and social benefit are wide.Raw material of the invention due to using north locality completely, it is certainly
The cost advantage that body has adapts to the demand of today's society, it is contemplated that and the profit ceramic tile output value increase by 30 higher than common whiteness~
50% or so, market economy effect is wide;It is rationally fast using local raw material, low temperature while good economic benefits are produced
Burn, the waste discharge of reduction, can reach good social benefit.
