Problems solved by technology

[0004] The main technical problem to be solved by the present invention is that the chemical composition of the ceramic body is unstable due to the large difference in the chemical composition of the animal bone, and the firing shrinkage of the artificial synthetic bone powder is relatively large. Low, easy to crack during the molding process, easy to crack the porcelain body after firing, and poor thermal stability of the product. The invention provides a method for preparing composite bone powder for bone china. The invention firstly treats poultry bones Carry out high-temperature cooking for preliminary degreasing and impurity removal, and then pass it through the environment of mixed gas to make the internal voids absorb aluminum ions and silicon ions, and then use microwave assistance to improve its stability, and complete degreasing modification at the same time, and finally use calcium phosphate Fill it with other substances to stabilize the chemical composition, so as to prepare the composite bone powder

example 1

[0017] Collect the poultry bones and put them in a steam boiler, set the temperature to 140°C, set the pressure to 1.0MPa, heat-preserve and cook for 3 hours, then pour the boiled beef bones into an ethanol solution with a mass fraction of 15% at 12°C for soaking, Cool down to room temperature, then take out the beef bones and remove the remaining meat slag on the surface; put the above-mentioned beef bones from which the meat slag has been removed in an oven, dry them at 100°C for 1 hour, and then put them into a grinder for crushing. 80 mesh sieve, according to the solid-liquid ratio of 1:3, the bovine bone particles obtained by sieving and the aluminum chloride solution with a mass fraction of 20% are mixed evenly, put into a high-pressure reactor, and the air in the reactor is discharged by using a mixed gas. Exhaust; the mixed gas is nitrogen, argon and monosilane mixed at a volume ratio of 12:4:1; after the air is discharged, set the speed at 200r / min, and raise the tempe...

Abstract

The invention discloses a method for preparing composite bone powder for bone china, belonging to the technical field of daily-use ceramics application. The present invention aims at the large difference in the chemical composition of animal bones at present, which makes the chemical composition of the ceramic body unstable, while the firing shrinkage of artificial synthetic bone meal is relatively large, and the drying strength of the ceramic body prepared with artificial synthetic bone meal is relatively low. It is easy to crack, the porcelain body is easy to burst after firing, and the thermal stability of the product is poor. The present invention provides a preparation method for composite bone powder for bone china. The present invention first conducts high-temperature cooking on poultry bones for preliminary degreasing Remove impurities, and then pass it through the environment of mixed gas to make the internal voids absorb aluminum ions and silicon ions, then improve its stability through microwave assistance, and complete degreasing modification at the same time, and finally fill it with calcium phosphate and other substances , to stabilize the chemical components, thereby preparing the composite bone meal.

Description

technical field [0001] The invention discloses a method for preparing composite bone powder for bone china, belonging to the technical field of daily-use ceramics application. Background technique [0002] Bone China is an internationally recognized high-grade daily-use fine porcelain, which has excellent characteristics such as fine porcelain, high whiteness, transparency, smooth glaze, and high mechanical strength. Its price is 5-10 times that of ordinary fine porcelain, but it is very popular among customers in the international market. Bone meal is the main raw material of bone china, and the dosage can reach 40% to 50% of the whole billet. The quality and dosage of bone meal have a great influence on the color tone, transparency, firing temperature and strength of bone china products. [0003] At present, there are only two kinds of bone meal commonly used in ceramic production. One is natural bone meal, that is, various bones of cattle, sheep, pigs, dogs, chickens, et...
