Bone porcelain blank 06

According to the experimental results, the bone porcelain bone corresponding cases, feldspar content increased deformation increase, but completely good; On the basis of the amount of feldspar, the light transmittance of bone porcelain bone meal less a bit poor, degeneration is smaller. Within the scope of this impact is less than feldspar quartz content, comprehensive consideration, should be based on 2, 4 reduce the dosage of feldspar, further experiments. Can also be based on 1, 3, appropriate increase the feldspar, the triangle method for further experiment method is commonly used bone porcelain formula test method, this method is based on all the vertices of an equilateral triangle don't represent a large variable values and the rest of the small value of the two factors, the law of value. With every vertex of A, B, C for accurate calculation, A, B, C, D, E, F the composition of each point is: the A— A 25% 75%, b B— 25% 75%, propyl C— A 25% 50%, b, c 25% D— A 50% 25%, b, c 25% E— A 25% 25%, b, c 50% F— B, c 50% 50% bone porcelain blank ingredients and its adsorption of water calculation on bone porcelain glaze formula based calculation, first of all, should consider the moisture of raw material, due to the difference of raw materials production, processing, storage, and its moisture change is very big, to do the bone porcelain glaze formula accurately, ceramic raw material moisture to deduct, that is to say, should be on calculation of the dry material. The calculation of adsorbed water: a wet weight of the raw material for G ( g) By 105 ~ 110 ℃ after drying to constant weight for the quality of the G1 ( g) , the raw material moisture content can be wet or dry basis said of the two methods. In the practical formula, general is according to the amount of dry material, through the conversion of wet base, and achieve the wet raw material for quality and to weigh. Does not contain the chemical composition of loi calculation in bone porcelain blank or glaze type calculation, often the results of chemical analysis of the burning, reducing the calculation for the only contains the mass fraction of oxide. Calculation method for: each component content = each score & divide; ( Total components of a burning reduction) As chemical composition of datong soil containing hot reduction and contains no burning down shown in the table below. Item by item in turn are calculated respectively. Bone China billet type of calculated by the formula composition, chemical composition of known formula calculation of bone porcelain body chemical composition can be according to the following steps; (1) with the chemical composition of bone China material multiplied by the percentage; (2) with the bone China of raw materials to the corresponding additive, and divided by the value after the deduction of the burning minus [ Example 3 - 1] A bone China ( Bone China) Body formula is: the bone powder 45%, 13% feldspar, quartz, 11% 31% such as kaolin, the chemical composition of bone China material are shown in table 3 - 11, try to calculate the chemical composition. Solution: the percentage of bone porcelain blank multiplied by each raw material chemical composition for a quick bone porcelain blank oxide content. Calculated by the chemical composition of bone porcelain slab type is calculated by the chemical composition of bone porcelain calculation method of billet type are as follows: (1) with mass fraction of each oxide, divided by the number of molecules of various oxides. (2) is obtained by dividing the number of molecules each oxide R2O3 calculation result by the sum of the above examples further calculation. Composed by chemical calculation formula of r&d staff can sometimes be collected according to chemical composition of bone porcelain body as to derive the approximate formula of the method is: (1) the bone porcelain material and converted into bone porcelain body, but contains no burning of reduction; (2) according to the experience is suitable for forming the first bone China with sufficient raw materials, such as various kinds of clay; (3) content in bone porcelain bone P2O5; (4) content in feldspar K2O again, Na2O (5) with a pure kaolinite meet the rest of the Al2O3 6 with quartz meet the rest of the SiO2 & ndash; Bone China hotel cutlery set to be continued. 。 。 。 。 。
