Acid-resistant mortar is a new type of acid-resistant and anti-corrosion material with strong prestress, composed of powdered binder, curing agent, admixture and acid-resistant filler through optimized formulation. Inorganic molecular materials are used as curing agents, and aluminosilicate is used as acid-resistant filler. It is a hydraulic cementing material with excellent heat and acid corrosion resistance and convenient for on-site construction. Acid-resistant mortar has high mechanical strength and excellent bonding performance. Acid-resistant and heat-resistant materials have high impermeability and can be formulated into high, medium and low temperature (construction environment temperature) series varieties to adapt to different seasons and different regions, and can ensure normal construction under different temperature conditions.
This product has good workability, strong adhesion, long initial setting time and construction operability time, rapid strength growth, strong impermeability, and does not require acidification treatment. It is easy to ensure that the density of masonry mortar joints is full, and overcomes the problem of ordinary water Glass acid-resistant mortar and mortar have shortcomings such as fast setting, short operating time, and inconvenient construction operations. They can significantly improve the air tightness and integrity of the chimney lining wall and the anti-corrosion ability of the lining. It is an ideal choice for tall chimney lining masonry construction. It is an ideal acid-resistant cementing material and can also be used in acid-resistant pools, tanks and other acid-resistant projects in petroleum, chemical, non-ferrous metallurgy and other industries.
Products Description
Water glass type acid-resistant cement is a powdery material made by grinding and mixing acid-resistant materials and hardeners in appropriate proportions. When used, it is mixed with an appropriate amount (about 40% or more) of water glass solution (it is strictly forbidden to mix with water), which can bond and harden, and has the performance of resisting the erosion of most liquid or gaseous inorganic and organic acids. It is a good anti-corrosion building material.
