Problems solved by technology

It can be used as an additive for ceramics, medicines, plastics, etc., and can also be used as a polishing agent, metallurgical release agent, etc. The raw material of bone charcoal is animal bones. The biggest advantage of bone charcoal powder is to prepare bone china, which is called bone china for short. It is called bone china, and its production began in England. The calcined bone is directly mixed with china clay and mineral flux to become a traditional hard porcelain raw material. Because of its unique shape, simplicity and clarity, white and delicate texture, bone china has long been Porcelain used by nobles in various countries is the only high-grade porcelain recognized in the world. One of the main raw materials of bone china is bone charcoal powder. Traditional bone charcoal powder is only crushed by ordinary calcination. When used as a bone china raw material, It has a certain limit line, resulting in low color fixation, and the texture of the prepared bone china is uneven, which is not favored by consumers

Embodiment 1

[0019] A method for preparing bone charcoal powder with strong color fixation for preparing bone china, comprising the following steps:

[0020] 1) Select fresh animal bones, then crush them, put them into a vacuum tank, add distilled water, the air pressure in the air tank is 0.01MPa, the temperature is 65°C, and heat for 2 hours;

[0021] 2) Put the aggregate processed in step 1 into the mixer, start the mixing, control the speed to 2500r / min, and stir at a high speed for 20 minutes, then sort it to remove the tendon and soil attached to the surface of the bone drop to get a clean bone;

[0022] 3) Put the aggregate treated in step 2 into the oil extraction pot, add benzene, pass the heating coil in the oil extraction pot into steam to heat continuously, and the benzene and the water in the aggregate form a benzene and water azeotrope , condensed by the condenser, benzene and water are separated, the benzene phase is refluxed into the oil extraction pot for circulation, and...

Abstract

A preparation method of bone charcoal powder with strong color fixation for preparing bone china, which relates to the technical field of bone charcoal powder production. The bone charcoal powder is preliminarily crushed, then degreased and degummed, and then the color is locked by salt water, and the color is fixed by the color fixing solution. It is obtained after washing, drying and grinding. The beneficial effects of the present invention are: the technological process of the present invention is simple, the technical method is reasonable and standardized, not only can normally prepare high-purity bone charcoal powder, but also ensures the blockage of its own chromaticity through immersion in salt water, and through cetyl chloride The mixture of pyridine, cetylpyridinium bromide and water is used to fix the color, which ensures a more balanced texture of the prepared bone charcoal powder, ensures a good raw material for the preparation of bone china, and solves the problem of poor color fixation of the traditionally prepared bone charcoal powder The problem is to ensure the whiteness of bone china, thereby enhancing the fineness and self-value of bone china.

Description

technical field [0001] The invention relates to the technical field of bone charcoal powder production, in particular to a method for preparing bone charcoal powder with strong color fixation for preparing bone china. Background technique [0002] Bone charcoal powder is insoluble in water, white block, particle size greater than 5mm, rich in elements such as phosphorus and calcium. It can be used as an additive for ceramics, medicines, plastics, etc., and can also be used as a polishing agent, metallurgical release agent, etc. The raw material of bone charcoal is animal bone, and the biggest advantage of bone charcoal powder is to prepare bone china. It is called bone china, and its production began in England. The calcined bone is directly mixed with china clay and mineral flux to become a traditional hard porcelain raw material. Porcelain used by nobles in various countries is the only high-grade porcelain recognized in the world. One of the main raw materials of bone ch...
