Acid-resistant bricks have excellent acid and heat resistance and can be used in acidic environments for long periods of time without damage. Acid proof bricks are commonly used for masonry lining of a variety of equipment requiring acid corrosion resistance.
Acid Proof bricks are also known as acid-resistant refractory bricks. The main function of acid-resistant refractory brick bricks is to resist the erosion of acidic substances, while being able to withstand high temperatures. The main components of acid-resistant bricks are quartz, feldspar, clay and other raw materials, which are made through high-temperature oxidative decomposition. Acid-resistant bricks are used as a lining material to cover the inner surface of containers, equipment or pipelines to resist the erosion of acidic or corrosive substances in order to protect the equipment from damage or corrosion.

Fireramo acid proof bricks have a water absorption rate of ≤0.2%, low water absorption rate, good anti-corrosion performance, and can be used in any place with peace of mind.
Acid proof bricks can withstand various concentrations of acidic media, such as sulfuric acid, hydrochloric acid, hydrofluoric acid, etc., providing reliable acid protection.
They are widely used in chemical equipment, such as reactors, storage tanks, towers, pipelines, etc., need to handle acidic substances frequently. Acid-resistant bricks, as a lining or building material for these equipments, can effectively resist the corrosion of acids on the equipments.
In refineries, petrochemical plants and gas processing plants, acid-resistant bricks are commonly used as lining or construction of equipment such as storage tanks, pipelines and reactors to prevent damage to the equipment by acids.
Acid proof bricks are used in metallurgical equipment, such as smelting furnaces, converters, electric furnaces and coal gasification furnaces. They are able to resist the erosion of acidic exhaust gases and acidic slag generated during the metallurgical process, providing structural stability and durability.
Acid-resistant bricks are used in power equipment such as chimneys, flue gas desulfurization units and denitrification units. They resist the erosion of acidic flue gases emitted from coal-fired power plants and power stations, protecting the durability and safety of the equipment.
Acid-resistant bricks are widely used in steel smelting equipment, such as converters, electric furnaces and blast furnaces. They can resist the erosion of acidic slag in the smelting process and protect the stable operation of the equipment.
Acid proof bricks are used in acid cabinets, acid tanks and acid-resistant countertops in laboratories. They can withstand the erosion of acidic reagents and chemicals in laboratories and provide a safe working environment.
Acid-resistant brick lining is a masonry method used in acid-resistant corrosive environments and is commonly used in corrosive environments in chemical plants, oil refineries, power plants and other locations. The following is a common acid-proof brick lining procedure:
Design and preparation: First, determine the specific dimensions, materials, and process for acid-resistant brick lining according to project requirements and design specifications. Prepare the required materials and tools to ensure compliance with safety and quality requirements.
Selection of materials: Select anticorrosive brick materials with good acid resistance, such as acid-resistant bricks and acid-resistant cement. Ensure that the selected material meets the design requirements and can withstand the specific chemical corrosion environment.
Surface Preparation: Prepare the surface to be masoned by making sure it is flat, dry and clean to ensure that the bricks will bond properly and provide optimum corrosion resistance.
Cutting and Positioning of Bricks: Cut and process acid-resistant brick materials as necessary according to design drawings or requirements, and then position and align them accurately according to design requirements.
Mortar Preparation and Construction: Prepare acid-resistant cement mortar and mix it according to a certain proportion. Then use the mortar to build up the acid-resistant bricks layer by layer, make sure that the mortar is evenly applied, there is no gap between the bricks, and the masonry is staggered according to the design requirements.
Curing and Maintenance: After completing the masonry, the acid-proof brick lining is cured and maintained. This usually involves slowly increasing the temperature or humidity to allow the mortar to dry and cure sufficiently to ensure that the masonry has adequate strength and corrosion resistance.
Quality Inspection and Acceptance: The completed acid-proof brick lining is inspected for quality to ensure that the quality of the masonry meets design requirements and safety standards. Acceptance is carried out upon completion and records are kept.

Ingredients: The ingredients of acid-resistant bricks mainly include siliceous materials, alumina materials, acid-resistant adhesives, acid-resistant mineral compounds and so on. The quality and proportion of these raw materials play a vital role in the quality of the bricks and need to be carefully prepared and tested.
Mixing: The raw materials are put into the mixer for mixing after fine screening and proportioning. During the mixing process, attention should be paid to the proportion and uniformity of various raw materials.
Molding: The mixed materials are pressed by the molding machine to make bricks of certain shapes and sizes.
Sintering: The molded bricks are sent to the sintering room for sintering. During the sintering process, the temperature is gradually increased to harden and form the brick blanks, and at the same time, the oxides in the quartz sand and kaolin undergo a reduction reaction to produce aluminum silicate and release gases.
Cooling: After sintering, the acid-resistant bricks need to be cooled to reduce their temperature and prevent them from deforming or cracking.
Inspection: After cooling, the acid-resistant bricks need to be inspected for quality, including appearance, size, strength and other aspects of the test.
Packaging: Acid-resistant bricks that pass the inspection are packaged to protect their surfaces and edges from damage, and at the same time facilitate transportation and use.
