Problems solved by technology

The disadvantage of dry-dipping graphite powder on the anode steel claws is that the amount of graphite powder dipped on the anode steel claws is small, and the dipping is uneven. After the phosphorus iron ring is pressed off, there is more iron on the anode steel claws, which is easy to scratch Anode steel claws; the disadvantages of dipping graphite powder blended with kerosene are: the smoke of the anode steel claws is relatively large when pouring, the working environment is poor, and the molten iron bubbles during casting, and the casting quality is poor; graphite in the related art The disadvantage of the base coating solution is: the price is more expensive, more than 30,000 / ton

Abstract

The invention provides a graphite-based coating solution for anode steel claws, which is composed of the following components by weight percentage: 18.2-23.3% of 1000-mesh graphite powder; 0.8-1.5% of water-soluble phenolic resin; and 0.12-0.33% of glass powder Carboxymethyl cellulose sodium 0.1-0.38%; alkylbenzene 0.1-0.25%; defoamer 0.1-0.25%; fungicide 0.04-0.13%; deionized water balance. Compared with the related technology, the invention has the advantages of effectively preventing the anode steel claws from sticking to iron, improving the working environment, improving the casting quality and reducing the production cost.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of coating liquids, in particular to a graphite-based coating liquid for anode steel claws. [0003] 【Background technique】 [0004] In order to facilitate the pressing off of the phosphorus iron ring, the anode steel claw is usually dry-dipped with graphite powder or graphite powder mixed with kerosene or coated with graphite-based coating solution before the anode steel claw is poured. The disadvantage of dry-dipping graphite powder on the anode steel claws is that the amount of graphite powder dipped on the anode steel claws is small, and the dipping is uneven. After the phosphorus iron ring is pressed off, there is more iron on the anode steel claws, which is easy to scratch Anode steel claws; the disadvantages of dipping graphite powder blended with kerosene are: the smoke of the anode steel claws is relatively large when pouring, the working environment is poor, and the molten iron bubbles duri...
