Embodiment Construction

[0011] The acid-proof and anti-corrosion mud-like material of the present invention is obtained by utilizing the characteristic of relatively high viscosity of the yellow clay, firstly purifying and enhancing the natural yellow clay, and then adding liquid acid-resistant materials into the dry yellow clay powder. Its method step is: put natural yellow clay in the container, add a certain amount of water, soil: water=2: 1.7, then add the separating agent sodium hexametaphosphate of 0.8% of soil weight, stir after 5 minutes, pour Put it into the settler for sedimentation, and take out the mud after the sand and gravel sink to the bottom; add tung oil to the mud for enhancement treatment, add 0.1 kg of tung oil to 7 kg of mud, and dry and pulverize the mud after stirring for 10-15 minutes to obtain High-performance yellow clay powder with stable performance, then add liquid acid-resistant material bisphenol A type unsaturated polyester resin into the dry yellow clay powder, stir w...

Abstract

The present invention discloses one kind of acid-proof anticorrosive muddy material prepared with yellow clay and through purification, modification to stabilize, and adding acid-proof material liquid through stirring. It is painted homogeneously onto the inner surface of leaching tank and electrolytic bath for smelting zinc and stoved to form the acid-proof lining. The acid-proof anticorrosive muddy material has simple production process, good operation performance, low cost, no toxicity and no pollution, and may be used widely in different plants to reach acid-proof anticorrosive surface.

Description

Technical field: [0001] The invention relates to an anti-corrosion material, in particular to an acid-resistant anti-corrosion mud material. Background technique: [0002] Zinc hydrometallurgy includes five processes of roasting, leaching, liquid cleaning, electrolysis and melting and casting. The leaching and electrolysis processes are carried out in the leaching tank and the electrolytic tank respectively, and the inner surface of the tank is in contact with the sulfuric acid solution during operation. In order to prevent the tank body from being corroded by acid, the inner surface of the tank needs to be lined with acid-resistant materials such as lead skin and epoxy resin. In the application, the cost of lining the lead skin is relatively high, and the process of lining the lining with epoxy resin is relatively complicated. Therefore, people are constantly looking for materials with lower cost and simple process to replace the acid-proof lining currently used. Inventi...
