Embodiment Construction

[0010] After the incoming inspection of various incoming raw materials is qualified, measure the moisture content of various raw materials, take the dry basis as the basis and adopt the invented formula for batching, and take by weight components, kaolin 40, Al 2 o 3 Powder 8, quartz sand 25, hydromica 10, bauxite 9, potassium sodium feldspar 8. Load the mill, and test the fineness after ball milling for 14 hours. The fineness is 250 mesh-300 mesh. After entering the coarse stock pool, pump again to screen and remove iron, then enter the fine stock pool, and then transport it to the mud press with a plunger pump. The mud pressing pressure is below 1.5MPa, and the water content of the mud is about 22% for unloading. Rough refining while unloading, the mud section after rough refining is sealed with a plastic bag and sent to the aging room, thus completing the processing of raw materials; after 72 hours of aging, it will go out of the aging warehouse for vacuum refining, and th...

Abstract

The invention provides a moderate-strength electric porcelain product and a manufacturing method of the moderate-strength electric porcelain product, wherein the moderate-strength electric porcelain product is produced by taking 35-40 parts of kaolin, 5-10 parts of Al2O3 powder, 25-30 parts of quartz sand, 10-15 parts of bauxite, 5-10 parts of hydromica, 5-10 parts of potassium-soda feldspar and the like in parts by weight as raw materials according to an ordinary processing technique of the electric porcelain product, wherein the kaolin, the quartz sand, the Al2O3 powder and the bauxite are framework materials of the product, and the hydromica and the potassium-soda feldspar are fluxing materials of the product. The moderate-strength electric porcelain product and the manufacturing method of the moderate-strength electric porcelain product provided by the invention have the beneficial effects that the method can be widely applied to the production of electric porcelain suspension insulator products with different strength grades such as 70kN, 80kN, 100kN and 120kN; the iron content of the products is decreased and the quality of the products is improved; the molding process of the preparation method is excellent, product defects are few, the qualification rate of semi-finished products is more than 97%, and the qualification rate of firing is more than 95%.

Description

technical field [0001] The invention relates to an electric porcelain product and a manufacturing method thereof, in particular to a medium-strength electric porcelain and a manufacturing method of the electric porcelain raw material formula. Background technique [0002] At present, most of the electric porcelain products and their raw material formulas are low-strength materials, and the strength is below 70kN. Only a few large state-owned enterprises such as Xi'an can produce 120-240KN products and the cost of raw material formula is 800-1000 yuan / ton. [0003] In the prior art, the raw material formula is composed by weight: kaolinite (Guangdong black mud) 6-8, kaolinite (Qingyuan washing mud) 10-15, Shanxi left cloud soil 3-5, hydromica (Liling North Chamber mud) 10-15, kaolinite (Jiangmen GF material) 3-5, potassium albite feldspar (Shangrao Dongxiang mud) 8-10, bauxite (Henan) 10-15, mixed mud of kaolin and hydromica ( Pingxiang ginger red mud) 20-27. The chemical co...
