Bone porcelain decoration 2 products

Objects of color depends on the properties of light waves of suction, bone porcelain paint colour is a result of metal elements and silicate or boric acid salt solid solution for the result of light waves in selective absorption and selective reflection. Metal coloring according to the basic shape and coloring mechanism of it is coloring and colloid coloring different molecular can be divided into two categories. ( 1) Staining molecules can stain into the molecules of the vitreous, vitreous color, such as iron, cobalt, nickel, copper, manganese, chromium, wrong is molecular colorants. Metal oxide coloring depends mainly on coloring ions melting valence state in the vitreous body coordination number. And valence and the coordination number as the flux composition, sintering temperature, atmosphere, etc. Elements of color and its valence relations. ( 2) Colloid coloring gel colorant in vitreous body is in the form of colloidal and color. Gold, silver, copper, cadmium sulfide, cadmium selenide is colloid colorant. ( 3) The paint table 7 - several basic and commonly used Is several based pigment, table 7 - 4 is a commonly used bone porcelain paint ( 4) Factors affecting color of ceramic pigment when use, hair colour is not immutable, bone porcelain glaze found the basis of different color is different, is affected by many factors, the main influencing factors are as follows. Ceramic pigment content (1) generally speaking, the influence of high color ever deeper levels (2) the bone porcelain pigment fineness of the fineness of the thinner, pigment dispersion, the greater the tinting strength stronger (3) the thicker the thickness of bone porcelain paint pigments, the deeper the color (4) bone porcelain glaze billet or flux properties the same pigment or metal oxides, the influence of the different bone porcelain glaze color different. As a small amount of copper oxide in bone China ( Bone China) Will appear in turquoise, while in ordinary porcelain body slightly yellow on general regular paint enterprises with product introduction will show the elements affecting the hair color. Coloring oxide coloring and the relationship between the basic glaze are shown in table 7 5, bone China commonly used oxide color and the relationship between the basic glaze are shown in table 7 6 (5) the influence of sintering temperature and atmosphere temperature and the atmosphere is different, different hair color. Iron is a typical representative of the people often speak of & other; White, green & throughout; And & other In the white yellow & throughout; Is the influence of iron. Iron bone porcelain glaze in reducing atmosphere is turquoise, yellow in the oxidizing atmosphere. Some ceramic pigments in the high temperature when using low temperature will appear color becomes shallow even blank. Bone China ( Bone China) Pigments used mostly for bone porcelain, and bone in-glazed porcelain glaze color pigments, on the burning under oxidizing atmosphere, enterprise directly buy suitable temperature of ceramic pigment. 6. The influence of bone China fuel too much water or high sulfur content in fuel, also can affect bone porcelain paint color, in general, there will be a & other; Throughout the hair meng &; The phenomenon. Bone porcelain pigment preparation of bone porcelain paint preparation using the traditional method of solid instead should more commonly, in recent years also developed a new package method, liquid phase synthesis and self-propagating synthesis, microwave sintering, such as, here only commonly used technology, do a general understanding. ( 1) Raw materials for bone porcelain paint materials general levels for industrial pure or chemical pure chemical raw materials. Bone porcelain material used according to its function is divided into colorants, color matrix and mineralizer three categories. Coloring is refers to the coloring materials, commonly used is various coloring oxide or hydroxide, carbonate, etc. Chromatophore a parent is usually colorless oxide, salts, mineral or solid solution, etc. — Tangshan bone porcelain cup dish suits to be continued. 。 。 。 。 。
