Acid-resistant ceramic tube Made from high-quality local kaolin, refractory clay, porcelain stone, and other raw materials through strict batching, ball milling, vacuum kneading, and extrusion processes.
The back of the acid-resistant ceramic tube can also be equipped with dovetail grooves, facilitating firm bonding with acid-resistant mortar during construction, preventing detachment, ensuring project quality, and extending service life.
Advantages of acid-resistant and heat-resistant ceramic tubes:
1. Acid-resistant and heat-resistant ceramic tubes feature high acid resistance and low water absorption.
2. Acid-resistant and heat-resistant ceramic tubes are not easily oxidized or contaminated by media at room temperature.
3. Acid-resistant and heat-resistant ceramic tubes have excellent corrosion resistance to acids such as wet chlorine, brine, hydrochloric acid, sulfuric acid, and nitric acid.
4. Acid-resistant and heat-resistant ceramic tubes have excellent corrosion resistance to alkalis of any concentration at room temperature.
Acid-resistant and heat-resistant brick plates Used as linings for various tanks, towers, vats, and mixing pools in non-ferrous metal smelting, chemical, fertilizer, and power industries, these are special materials resistant to high temperature, cold, and strong acid corrosion.
