Problems solved by technology

Furnaces used for high-temperature treatment are mostly built with fireproof bricks due to their large volume. In order to produce products with higher purity and improve the service life of the furnace, a lining structure needs to be installed inside the furnace to isolate the material from the furnace body. However, there is currently a lack of a furnace lining material suitable for the production of white carbon black.

Abstract

The invention provides a lining material for a furnace for producing white carbon black and relates to the field of new materials. The lining material is made from, by weight, 2.6 parts of hydrochloric acid, 0.2 part of vanadium (III) acetylacetonate, 2 parts of basic zirconium carbonate, and 7 parts of bentonite. The lining material of the invention is suitable for a furnace for producing white carbon black and can act as a furnace lining material to avoid the direct contact between production materials for the white carbon black and a furnace body, improve product purity and prolong the life of the furnace; the lining material features high temperature resistance and corrosion resistance.

Description

technical field [0001] The invention relates to the field of new materials, in particular to a furnace lining material used for producing white carbon black. Background technique [0002] In the prior art, the production process of white carbon black is to uniformly mix quartz sand and soda ash, and treat them at high temperature in a furnace. Furnaces used for high-temperature treatment are mostly built with fireproof bricks due to their large volume. In order to produce products with higher purity and improve the service life of the furnace, a lining structure needs to be installed inside the furnace to isolate the material from the furnace body. However, there is currently a lack of a furnace lining material suitable for producing white carbon black. Contents of the invention [0003] The object of the present invention is to provide a furnace lining material for producing white carbon black, to solve the above technical problems. [0004] The technical problem to be ...
