Acid resistance is the ability of refractory materials to resist acid attack. Acid-resistant refractory materials include acid-resistant bricks and acid-resistant refractory castables. Rongsheng refractory manufacturers can provide high-quality acid-resistant bricks, anti-corrosion acid-resistant carbon bricks, acid-resistant castables, acid-resistant cement, etc. Our acid-resistant refractory products are reliable in quality and perfect in service.
Lightweight acid-resistant brick flue refractory brick heat insulation and acid resistance are good
The characteristics of acid-resistant bricks are anti-corrosion, high acid and alkali resistance, low water absorption, not easy to oxidize and decompose at room temperature, and not easy to be polluted by media. Acid-resistant bricks are anti-corrosion and acid-resistant materials made of quartz, feldspar, and clay as the main raw materials and fired at high temperatures in a kiln. It has the characteristics of high acid resistance, low water absorption, not easy to oxidize at room temperature, and not easy to be polluted by media. It has excellent characteristics such as strong pressure resistance, corrosion resistance, easy cleaning, and acid and alkali resistance.
Acid-resistant cement resistant to high-temperature flue gas at 1000°C
Acid-resistant cement can withstand 1000°C in wet flue gas, and can also be used as a common bonding material for acid-resistant brick anticorrosion. Maybe you are not a professional in the construction industry and don’t know what acid-resistant mortar is. However, acid-resistant cement is commonly used in some industrial fields and in the process of building construction. It is an important decoration material used in many large factories or construction sites. It is also a commonly used adhesive for acid-resistant bricks in the field of chemical anti-corrosion.
Performance and characteristics of acid-resistant and heat-resistant series of acid-resistant cement anti-corrosion materials
- Clay is a new type of anti-corrosion material with strong prestress, which is composed of potassium silicate as a binder, inorganic molecular material as a curing agent, and aluminosilicate as an acid-resistant filler.
- The cement has high mechanical strength and excellent bonding performance. Especially in masonry granite blocks, acid-resistant tiles, porcelain plates, and cement, the bonding force is greater than that of the parent body.
- Acid-resistant and heat-resistant materials are stable in various concentrations of organic acids and inorganic acids. Especially in dilute acid, industrial water, and neutral aqueous solution, no crystalline salt will be produced. And has high impermeability.
- Good heat resistance, the lining in the titanium dioxide rotary kiln, the service temperature is as high as 900 ℃ ~ 1000 ℃.
- The cement adopts a non-toxic curing agent, which is non-toxic to operators and construction personnel. Appraised by the medical and health department, it can be used in food, medicine, and other equipment anti-corrosion projects.
- Compared with organic cement, acid-resistant, and heat-resistant materials are cheaper. It not only has the same corrosion resistance performance as organic cement but also has the unique performance of corrosion resistance to strong oxidizing medium.
- Curing at room temperature, simple construction, convenient use, easy transportation, and moisture-proof storage.
Application Advantages of RS Acid-Resistant Castables
Acid-resistant castables are castables that can resist corrosion by acidic media such as nitric acid, hydrochloric acid, sulfuric acid, and acetic acid at a temperature of 800-1200 °C. They are generally made of acid-resistant aggregates, such as silica, cast stone, wax stone, diabase, and other particles, as well as acid-resistant material powders such as waste silica bricks, silica, waste porcelain, cast stone, etc., and water glass is used as a binder. obtained castables. Good acid resistance. It is used in metallurgy, chemical industry, and other departments. However, it has poor corrosion resistance to phosphoric acid, hydrofluoric acid, and high fatty acids. The composition of acid-resistant castables mainly includes water glass, hardening accelerator, acid-resistant refractory aggregate, powder, etc. Acid-resistant refractory aggregates and powders mainly include clay, silicon, cast stone, wax stone, andesite, etc.
The advantage of acid-resistant castables is energy saving. High production efficiency. The production process of refractory castables is simple, and its production efficiency is 4 to 9 times that of refractory bricks. High construction efficiency. The construction efficiency of monolithic refractories is 6 to 15 times that of bricklaying. It can be shaped arbitrarily. It can be used to make the whole special-shaped furnace lining, and it can also be used to quickly repair the kiln to improve its service life and operation rate. Suitable for all kinds of high-temperature projects. The material can be used to prepare masonry materials with excellent heat resistance, shock resistance, harmful gas and slag corrosion, peeling resistance, and heat insulation.
Acid-resistant castables are used in industrial kilns, and acid-resistant castables can be seen in other industrial applications. Acid-resistant castables are finished products of refractory materials, and their main function is to be used in the repair of various industrial buildings. It can make reasonable repairs on the damaged parts of the kiln, so as to ensure the normal operation of the kiln. Acid-resistant castables are suitable for the repair of various special buildings and can be said to be the most widely used refractory products.
