Bone porcelain decoration 3 products

Mineralizer is generally alkaline oxides, boric acid, fluoride, clinker can decrease the sintering temperature of raw materials, such as general and manufacturing method according to the types of bone porcelain paint to order selected bone porcelain material fineness is in commonly 200 ~ 400 mesh. ( 2) Bone China ingredients and mix according to the formula for accurate configuration, and mixing made mixtures. Hybrid method has two kinds of dry method and wet method, dry mixing is will have processed the raw material, after weighing in the dry mixing machine. Wet mixing is put all kinds of raw material after weighing goal mixed grinding mill, blend to need to dry processing. Generally contain water soluble materials using dry mix. The process is the basis of bone porcelain paint, mixed uneven directly affect the quality of the bone porcelain products. ( 3) Calcination will mix well and dry with loads of sagger calcining synthetic material, calcination temperature, atmosphere, time, and a burning method according to the paint type and formula. More commonly adopted oxidizing atmosphere firing, and some bone porcelain materials need to packaging, using oxidizing atmosphere firing. ( 4) After crushing, washing and drying bone porcelain paint calcination will be available after crushing processing, such as, the hair of pigment color ability is related to grain size, particle size, the more the better fine hair color. Some pigment reaction is not after calcining, affect normal hair color, need to just can use after washing, usually with dilute hydrochloric acid or dilute nitric acid repeated washing with warm water, until he wash the residue. After crushing processing, such as the pigment can be used after drying. The preparation of ceramic pigment process as shown in figure 7 6. Color paper by printing decorative ceramic decal paper is the design pattern with bone porcelain pigment printed on special paper, Usually with big film paper and small film paper) , you can move on the bone porcelain decorated bone China print. Bone China decal decoration is bone China ( Bone China) The adornment of the commonly used method, the method is simple in operation, rich colors, good consistency. In the history of our country's modern bone porcelain, ceramic decals on adornment basically can be divided into three stages. The first stage ( Glue paper) Is a lithograph ( Stereotype printing) , rough process, the performance is poor, in the 1960 s has been eliminated. Phase ( The big film color paper) Is offset lithography, popular in 60 ~ 80 s of the 20th century, there are some factories in use. This paper is to put the bone porcelain pigment printed on the butyral membranes ( Commonly known as the big film color paper) , as a result of offset lithography, bone porcelain products are poor adhesion, color layer owe all bright, the color is not enough light after baking, explosive flower, shortcomings and so on easy to deformation, big film color paper being phased out. At present in the third stage ( Small film color paper) , that is, the silk screen printing stage. The classification of bone porcelain color paper according to the paper ( The bottom paper) Nature and can be divided into three types: one is the butyl aldehyde film paper ( The big film color paper) ; The second is the quality of rough under glaze color paper; Three is the general moving water decals ( Small film color paper) 。 Butyral film color paper also called & other; Alcohol color paper & throughout; , it is to use butyral and alcohol as raw material, made of thin film for the bottom paper, on the surface of the bottom paper printing design, because the cost is low, the price is only 1/3 of the moving water decals, process and effect of basic can meet the requirements of decoration, and for ordinary bone porcelain, the technology still has great market. But for bone China ( Bone China) Use this color paper shortcoming is also very prominent. Big film color paper because the lining paper butyral film thickness, use mouth behind not neat, printing design, difficult to register when the resolution is not enough, so the bone China pattern and its poor ductility, not stick to the irregular plane, combined with film printing metal preparation, and so does bone porcelain ( Bone China) The decoration. — Tangshan fish bone porcelain dish to be continued. 。 。 。 。 。
