Abstract
One kind replaces feldspar, quartz and part kaolin using sericite china stone, produces the blank formulation of Household stoneware.Belong to domestic ceramics technical field.Technical scheme shows as：With the porcelain stone of quality 50 70%, 30 50% fire clay is equipped with, and adds the blank that a small amount of mineralizer constitutes, produce Household stoneware.The problems such as solving a large amount of shortages of resources caused using kaolin, china clay and feldspar in conventional formulation, high cost.Take full advantage of rich reserves, steady quality, porcelain stone with low cost.The formula dispensing low cost；Performance is good；Can low temperature and fast firing；Energy saving.With obvious economic benefit and social benefit, can in Shi porcelain industries wide popularization and application.
Description
Technical field
The present invention relates to a kind of sericite matter Household stoneware low temperature blank formulation, belong to domestic ceramics technical field.
Background technology
Shi porcelain, it is a class ceramic between pottery and porcelain, usual also referred to as stoneware.For domestic ceramics device
The production of ware, meal tea set and craft artistic pottery and porcelain.
Up to the present, Household stoneware blank mainly has two big types：One class is with feldspar as flux（Feldspar-quartz-
Kaolin）Type, Equations of The Second Kind is with albite as flux（Albite-quartz-kaolin）Type.Two kinds of blanks respectively have its excellent scarce
Point, first kind firing temperature is higher, and fuel expends more；Equations of The Second Kind firing range is not wide, and heat endurance is poor, and product is strong
Degree is not high.
Shi porcelain products are all the fashion abroad, and porcelain has been exceeded on international goods is easy, occupy very big proportion, domestic a large amount of
More than 20 years of production outlet
Because Shi porcelain products are more thick and heavy, add and produce all the year round, material consumption is huge, mine is increasingly exhausted, it is in short supply,
Price is soaring, cost increase.It is the pressing problem that current Shi porcelain industry faces to find alternative materials.
Sericite china stone (abbreviation porcelain stone) is a kind of traditional porcelain making raw material, and chemical composition is compared with feldspar.K2O,
Na2O and Al2O3It is relatively low, and SiO2Content is higher, thus melt temperature is high compared with feldspar.In the prior art, typically with porcelain stone with
Kaolin dispensing produces porcelain.It is (sericite-quartz-kaolin) using the sericite class mineral in porcelain stone as flux
System porcelain, abbreviation sericite china.
Porcelain stone is used as porcelain making raw material, there is very long history.The place of production is a lot, rich reserves.Ingredient stability
It is its a big characteristic.
But using porcelain stone as the primary raw material for making Shi porcelain, particularly for the blank of easy fired, have not been reported
And example.
The purpose of the present invention, seeks to develop a kind of Low-temperature stoneware formula that can widely apply porcelain stone, widens Shi porcelain raw materials
Source, reduces production cost.
The content of the invention
The technical problem to be solved in the present invention, is directed to the weakness of prior art, there is provided one kind adapts to low temperature and quickly burns
Into thermally-stabilised good, intensity is high, while the Shi porcelain blank formulations that can be matched with the glaze of existing shades of colour.
Solve the above problems and take following technical scheme：For the Al in porcelain stone2O3It is relatively low；Fire clay is added, for burning
Into temperature addition sepiolite higher.
The invention is characterized in that:
1. the whole feldspars in existing formula are replaced with porcelain stone, all quartz and part kaolin, replaced with fire clay
The kaolin of remainder.Household stoneware is manufactured using the blank that sepiolite is constituted as mineralizer.
2. the proper proportion and allowed band of each component during experimental study is formulated.
Sepiolite is a kind of magnesia fireproof clay, in history for making saggar.A small amount of sepiolite, energy are added in blank
Blank firing temperature is reduced, liquid phase is formed at a lower temperature, accelerate the generation of mullite, improve the mechanical strength of product.Together
When can also form a part of cordierite, reduce the coefficient of expansion of blank, promote the combination of base and glaze, the emergency heat and cooling property resistance of improvement product
Become performance.Improve heat endurance.
The species of mineralizer can be sepiolite-type attaclay, talcum and dolomite.The selection of species can be according to goods
The factor such as source and cost determines.
When the sericite matter Shi porcelain low temperatures blank formulation provided using the present invention produces Shi porcelain, production technology and existing life
Production. art is identical.
It is an advantage of the invention that:
1. resource is sufficiently used, the contradiction that the raw material supply of Shi porcelain is nervous, cost is very high is alleviated.(
Blank cost reduces 50-60%)
2. the weakness of existing formula is overcome, can be rapidly fired to, energy saving.
3. it is high that simple, stabilization, good operation performance, product percent of pass are formulated.
4. product heat endurance is good, and intensity is high.
