Bone porcelain blank 05

( 1) Determine the scope of the chemical composition determined based on the experience formula of the basic scope, bone China meal 42% ~ 5%, 8% ~ 10% feldspar, quartz (8% ~ 10%, clay is 20% ~ 40%. According to the ceramic raw material chemical composition and sintering performance, preliminarily determine formula. Bone China ( 2) According to the requirement of forming performance because of poor bone model, when considering formula according to the different forming methods corresponding to pay attention to the selection and matching of clay. Forming the grouting with mud, clay content can be appropriately reduced, for can use molding clay, bentonite content should be appropriate. When sticky and choose to use, try to mix with the method of compound clay, domestic raw materials commonly used with bone porcelain body. Bone China ( 3) Experiment and modified in consideration of the above factors and the actual experiment, on the basis of trial and error will choose good comprehensive performance for pilot and production. Bone China orthogonal experiment design method, bone China ( Bone China) Glaze formula is composed of a variety of raw materials, often change a factor, its performance has very big difference. If the process test, according to a one factor is difficult or almost impossible in a short period of time to get satisfactory results. Law and the orthogonal experiment was to investigate and deal with many factors of a scientific method, it is based on the mathematical statistics theory, combined with practical production experience using a set of normalized orthogonal table, scientifically selecting test condition, reasonable arrangement of the experiment. Orthogonal experiment design method put forward by Japanese quality management expert taguchi xuan, referred to as the local standard orthogonal test method is a kind of very practical test method, some say a engineering technical personnel if they do not grasp the orthogonal experiment design method, is only half the engineers & throughout; 。 Bone China ( 1) The characteristics of this method (1) to arrange test set of tables, analysis have rules to follow. Bone China (2) saving time, energy saving, consumption, fewer test, representative, the effect is good. Bone China (3) the influence factors of test results of primary and secondary distinct, indicate the direction for further tests. Bone China orthogonal test is often conducted by applying orthogonal table, with the following symbol: bone porcelain Ln ( ji) L&mdash type; The symbol of the orthogonal table; n— Orthogonal table rows ( Test, test plan) ; Bone China j— The digital (orthogonal table A series of factors) ; Bone China i— The number of columns (of the orthogonal table The number of test factors) 。 Bone China ( 2) Orthogonal experiment test steps (1) clear aims, determine assessment indicators. Bone China (2) pick factors, choose a level, uncertainty level table. Bone China (3) choose appropriate orthogonal table. Bone China factors (4) orthogonal table, on a level test scheme is determined, and tested according to the experimental schemes. Bone China (5) test results analysis. Bone China ( 3) Commonly used orthogonal test table according to the factors of the shape, the orthogonal table can be divided into level have the same number of levels orthogonal table and the number of different mixed orthogonal table. Bone China ( 4) For example using simple 2 level 3 factors orthogonal table do bone China ( Bone China) Body formula experiment considers three main factors affecting bone powder, feldspar, quartz, take meal for 42, 45, feldspar is 8, 12, quartz of 7, 10, other clay ceramic raw material proportioning, according to the orthogonal table formula.
