Abstract

The invention provides a cristobalite high strength porcelain formula, aiming to solve the technical problem that in the traditional high strength electric porcelain formula, the proportion of aluminite reaches 35-45 percent and the proportion of feldspar is 15-20 percent, and if the high strength electric porcelain is expected to be obtained, the production cost of the electric porcelain is bound to increase because the price of the aluminite is highest in the raw materials used by the electric porcelain formula. In the cristobalite high strength porcelain formula, the key point is that the blank formula comprises 21-28 percent of aluminite, 5-10 percent of feldspar, 11-17 percent of kaolinites clay containing quartzose, 19-25 percent of hard kaolinites clay and the balance of illite clay. The invention is used for producing high-voltage electric porcelain.

Description

technical field [0001] The invention relates to a formula of high-voltage electric porcelain, in particular to a formula of cristobalite high-strength electric porcelain. Background technique [0002] With the continuous development of the electric power industry, ordinary strength high-voltage electric porcelain can no longer meet the existing market demand, and high-strength high-voltage electric porcelain needs to be produced. In order to improve the strength of high-voltage electric porcelain, it is common practice to increase the content of alumite, that is, the content of aluminum oxide, in the electric porcelain formula. In the current high-strength electric porcelain formula, the proportion of alumite has reached 35-45%, and the proportion of feldspar is 15-20%. Among the raw materials used in the formula of electric porcelain, the price of alum stone is the highest. If you want to obtain high-strength electric porcelain, it will inevitably increase the production c...
