Bone porcelain blank 11

(4) after stale can improve the strength of the bone porcelain body, reduce the deformation of chance of burning plastic bone porcelain clay material after stale, can increase the plastic deformation after grouting with mud stale, reduce bone porcelain, reduce viscosity, liquidity, empty pulp are improved, beneficial to the improvement of the yield. For tired for a long time, covers an area of big, interrupt the continuity of production process of considering factory in many times will usually bone porcelain clay material vacuum pug for cliche. Plastic forming method of the preparation of bone porcelain blank plastic clay material preparation can use molding is the external force on plasticity of bone China, processing, make the action of external force bone porcelain blank plastic deformation and made into shapes that accords with a requirement of bone porcelain body forming method. Plasticity bone porcelain clay material preparation generally have the following kinds of technological process. Bone porcelain pug plasticity performance requirements using bone porcelain clay molding material shall meet the following basic requirements: (1) there are appropriate plasticity. (2) the appropriate ductility; (3) the appropriate release; (4) uniform structure and moisture. (5) high dry strength; 6. Less drying shrinkage; All landowners suitable particle size; Was less air content. Grouting method of forming bone porcelain blank is the forming process of the preparation of grouting ceramics ( Bone China) The basic forming process in the production. Forming is the preparation good mud grouting injection porous model, using water imbibition of the mould, make the slurry in the mold wall to form a uniform thickness of layer of mud, its thickness upset with the extension of time, until you reach the required thickness of process. Two kinds of forming into hollow grouting and solid grouting. Forming is grouting hollow grouting process after the excess sludge poured out. And forming solid grouting is mud until all full of model can release. Suitable for a variety of shape ceramic (grouting forming Bone China) Forming products. Most complicated shape and thin wall, irregular or bulky shape can be grouting forming. Such as bone porcelain, bone China coffee pot, teapot bone porcelain, bone China milk sugar cylinder cylinder, bone porcelain vase hollow products, such as general forming hollow grouting method. And like fish bone porcelain plate, chopsticks holder using solid forming grouting. The preparation of mud grouting ( 1) Ball mill pulping process ball mill pulping process is simple, basic bone porcelain slurry preparation technology. The process is as follows: the coarse crushing, pieces of hard material and soft material & rarr; Ingredients & rarr; Ball mill & rarr; Mixing pool & rarr; Sieving iron & rarr; Mud barrels/pool & rarr; Grouting forming ball mill pulping process has the advantage of less equipment, cycle is short, the labor, low cost, simple operation, less defect is bone China mud grouting performance have larger fluctuation, stability is bad, suitable general bone China products for demand is not high. ( 2) Mud section of the slurry process the process in a vacuum pug with plastic bone porcelain clay material preparation before the same, the process is as follows: the coarse crushing, pieces of hard material and soft material & rarr; Ingredients & rarr; Ball mill & rarr; Filter mud, a pug & rarr; Stale & rarr; Vacuum pug & rarr; Stir the pulp & rarr; Sieving iron & rarr; Mud barrels/pool & rarr; The forming of the grouting. Forming is the use of process performance requirements of pulp slurry grouting slurry liquid, hydrophobicity, and the model for forming the corresponding water imbibition. In order to obtain high quality bone porcelain body, the performance of the mud to the grouting has the following requirements. — Bone bowls plates to be continued. 。 。 。 。 。
