Acid-resistant bricks are mainly made of quartz, feldspar, etc., which are made of pyrolytic materials made of pyrolysis. They have high acid and alkali resistance, low water absorption, and are not easily oxidized at room temperature. It is not easily contaminated by medium, and has excellent anti-corrosion effects except for hydrofluoric acid and hot phosphoric acid, for warm chlorine salt water, hydrochloric acid, sulfuric acid, nitric acid and other alkalis at any concentration under normal temperature. The following Xiaobian introduces the basic treatment of acid-resisting brick construction and the examination of the matrix of acid-resistant bricks. Acid resistant brick construction base treatment 1. The cement mortar or concrete should be tightly combined together, and there should be no phenomena such as cracking of honeycomb and puddles from the sand and shell, and the slope of the grass-roots layer must meet the requirements. The flatness needs to be checked with a 2 meter ruler. The allowable clearance should not be more than 5 mm. 2. When the cement mortar and concrete base are used for block paving, the yin and yang corners of the base should be at right angles. When carrying out other kinds of acid-resisting bricks for anti-corrosion construction, the base yin and yang angles should be made beveled or rounded. 3. The base layer must be kept dry. The moisture ratio in layers 25 mm deep should not exceed 6%. If there are special requirements for the design humidity, the construction should be carried out according to the design requirements. 4, the surface of the base can not have floating dust, cement and loose parts, so use sandblasting or wire brush to grind the surface before construction, need to use a soft brush to deal with, as far as possible a perfect treatment, to achieve the completion of the construction requirements of acid brick . Acid Resistant Brick Paste Inspection 1. Brick-laying is mainly based on concrete. These matrices must be inspected and accepted in accordance with relevant regulations or standards before construction. Only qualified construction can be carried out. 2. The surface of the concrete must be solid, dense, and smooth, and there should be no defects such as sanding, cracks, honeycombs, and pockmarks. 3. The surface roughness of concrete shall be checked with a straight ruler of 3 meters. The allowable clearance shall not be greater than 6mm. The slope shall conform to the design provisions. 4, the concrete must be completely cured, the surface of the water content within 20mm should be less than 6%. 5. The surface of the construction must be clean and tidy, and there must be no floating ash, cement, steel and other debris. Editor's summary: The basic treatment of acid-resisting brick construction and the examination of the matrix of acid-resisting bricks are introduced here. I hope to be helpful to everyone.
