Model Number: hongtai
Minimum Order Quantity:



The main component of acid-resistant brick is silica, which forms a large amount of mullite under high temperature roasting, which is a kind of material with high acid resistance. Because of its tight structure and low water absorption, acid-resistant brick can also be used at normal temperature. It is resistant to any concentration of alkaline medium, but it is not resistant to high temperature. The acid-resistant brick contains more than 70% of silica and is sintered. It is widely used in the chemical industry for acid-groove, acid well, acid storage and The acid-bearing impacted ground.

Acid-resistant bricks • Instructions for use

Widely used in petroleum, chemical, pharmaceutical, food, paper, fertilizer, pesticide, chemical fiber, textile, smelting, power plant and other industries, as well as anti-corrosion lining of towers, pools, tanks, tanks, and in sewage treatment engineering and open ground, etc. The workplace is designed to withstand acid and corrosion. Acid-resistant bricks are resistant to most media except hydrofluoric acid, hot phosphorus, and concentrated alkali. They have excellent anti-corrosion to wet chlorine brine, hydrochloric acid, sulfuric acid, nitric acid and other alkalis at room temperature. effect.

General epoxy resin, acid-resistant clay, acid-resistant cement paving, when paving, can be constructed according to the manufacturer's product manual; use oxalic acid to clean the concrete surface to achieve acid-base neutralization; industrial porcelain acid-resistant brick, the width of the joint is about 8 10mm, the seam depth is equal to the brick thickness to prevent leakage; after the paving is finished, the groove acid is used to wash the surface to help be more firm.
