2) mud is prepared in grinding;
3) mud sieve after deironing, carry out blank forming, and be fired into fusible cut-out ceramic shell at 1180 ~ 1250 DEG C.
Described step 2) in use wet ball grinding technique to prepare mud in ball mill.
Described step 2) controlling dimension is less than or equal to the granular mass content of 10 μm 75 ~ 90% in the mud prepared.
Described step 3) in the screen cloth that sieves of mud be 140 ~ 200 orders.
Relative to existing technologies, fusible cut-out ceramic shell blank formulation provided by the invention, mainly contains following advantage:
1, the waste material adopting isostatic pressed electric porcelain production to reclaim, as in blank main raw material, significantly reduces raw materials cost, the high alumina content simultaneously in waste material, and also ensure that the performance such as mechanical, electrical, hot of goods, insulating property are good;
2, by adding feldspar as flux raw material, effectively can reduce the one-tenth porcelain temperature of blank sintering, save energy, reducing manufacturing cost;
3, the use of water reducer, can be reduced the moisture content of mud, improves the suspension of mud; The use of additive, makes to form water barrier layer between base substrate powder particles, reduces the water regain of later stage base substrate, also ensure that blank has the dry tenacity of certain associativity and base substrate;
So, present invention uses the waste material that isostatic pressed electric porcelain production reclaims, improve raw material availability, use feldspar raw material and additive etc. simultaneously, be beneficial to the characteristic of ceramic dry method compacting, reduce raw materials cost and the manufacturing cost of ceramic.
In fusible cut-out ceramic shell preparation method of the present invention, owing to employing waste material, feldspar flux raw material and additive etc. that isostatic pressed electric porcelain production reclaims as blank, relative to normal one-tenth porcelain temperature, effectively can reduce goods and become porcelain temperature 40 ~ 60 DEG C, greatly reduce the consumption of heat energy when burning till; And processing performance is excellent, low cost of manufacture, by grinding, sieving, the step such as deironing, makes quality product better, improving product electric property.
