Lightweight acid resistant castable

Introduction

Acid resistant castable is made from aluminate cement, high alumina fines, ceramic particles, and several additives. This product has light volume, high compressive strength, and resistance to acid and acidic gas corrosion. Featuring insulation, insulation, low water absorption, and easy construction, it is an ideal product for construction in areas with alkali corrosion resistance at high temperatures. Good workability, strong bonding force, long initial setting time and construction operability time, fast strength growth, strong impermeability, no need for acidification treatment, easy to ensure the compactness and fullness of masonry joints, can significantly improve the airtightness, integrity, and corrosion resistance of the chimney lining wall. It is an ideal bonding material for high smoke, high-temperature flue, and air duct lining, and can also be used in acid resistant tanks in industries such as petroleum, chemical, and non-ferrous metallurgy Acid resistant engineering such as tanks. Acid resistant bricks, acid resistant mastic, and coating materials are refractory materials developed by our company for the insulation of power plant boiler chimneys and heating network pipelines. They have the characteristics of acid corrosion resistance, temperature resistance, heat stability, and convenient construction.
