1. Overview of acid-resistant mortar
Acid-resistant mortar is a mortar specially designed to resist corrosion by chemically corrosive substances. It is usually composed of aluminate cement or acid-resistant liquid binder, aggregates and additives, and has high acid resistance and good wear resistance and compression resistance. Acid-resistant mortar is often used in anti-corrosion projects in chemical, pharmaceutical, food and other industries, such as the anti-corrosion of the inner walls of reactors, tanks, pipelines, etc.
2. Composition of acid-resistant mortar
Acid-resistant mortar is mainly composed of acid-resistant liquid binder or refractory cement, aggregates and additives. Among them, special cement is the main cementing material of acid-resistant mortar, which has the characteristics of strong resistance to acidic substances. Aggregates mainly provide the strength and wear resistance of acid-resistant mortar. Additives include reinforcing agents, dispersants, retarder, etc., which can improve the performance of acid-resistant mortar and make it more adaptable and durable.
3. Preparation of acid-resistant mortar
The preparation process of acid-resistant mortar mainly includes the following steps:
1. Ingredients: Mix binders, aggregates and additives together in a certain proportion.
2. Stirring: Add an appropriate amount of liquid binding agent to the mixed materials and stir until they are fully mixed.
3. Pouring: Pour the mixed acid-resistant mortar onto the surface of the object that needs anti-corrosion and cover it evenly.
4. Maintenance: After the initial setting of the acid-resistant mortar, appropriate maintenance is required to ensure its strength and durability.
4. Performance characteristics of acid-resistant mortar
Acid-resistant mortar has the following performance characteristics:
1. It has good acid resistance and can resist the erosion of most chemical corrosive substances, extending the service life of the equipment.
2. It has good wear resistance and can resist the friction and impact of materials to maintain long-term stable operation of the equipment.
3. It has high compressive strength and can withstand high pressure, ensuring the load-bearing capacity of the equipment.
4. Strong adaptability, can be used in different environments, such as high temperature, low temperature, humidity, etc.
5. Application scope of acid-resistant mortar
Acid-resistant mortar is widely used in the following fields:
1. Chemical industry: anti-corrosion of inner walls of reactors, tanks, pipelines, etc.
2. Other industries: such as inner wall anti-corrosion of anti-corrosion equipment and pipelines in electroplating, electric power, building materials, metallurgy and other industries.
