AI Technical Summary

Technical Problem

During the firing process of existing insulators, the anti-adhesive layer of the anti-adhesive material brush on the carrier is prone to powder loss and cracking, resulting in low processing efficiency for workers and poor product quality.

Method used

A release material formula including 30-50 parts of industrial alumina, 35-55 parts of quartz powder, 10-30 parts of kaolin and 0.5-2 parts of sodium carboxymethylcellulose is used to improve adhesion and water retention by adding sodium carboxymethylcellulose to ensure that the release layer is not prone to cracking after firing.

Benefits of technology

It effectively solves the problems of powder loss and cracking of the anti-adhesive layer, extends the service life, reduces the number of times of brushing anti-adhesive materials, reduces labor intensity and cost, and improves the quality and qualification rate of the product.

Abstract

The invention relates to the technical field of insulator firing, and particularly discloses an anti-sticking material for insulator firing, which comprises 30-50 parts of industrial alumina, 35-55 parts of quartz powder, 10-30 parts of kaolin and 0.5-2 parts of sodium carboxymethyl cellulose. The preparation method of the anti-sticking material for firing the insulator comprises the following steps: S1, preparing materials: taking corresponding parts of raw materials according to the components in the anti-sticking material for firing the insulator; and S2, mixing the ingredients, adding water, and grinding into the anti-sticking slurry. The invention also provides a use method of the anti-sticking material for firing the insulator. The use method comprises the following steps: step 1, adding water into the anti-sticking material for firing the insulator, and grinding into anti-sticking slurry; and 2, brushing the anti-sticking slurry on the surface of the bearing body. The scheme is used for solving the problems that in the prior art, an anti-sticking layer prepared by brushing an anti-sticking material on a bearing body is prone to powder falling and cracking after an insulator porcelain piece is sintered.
