Water Absorption 0.2-0.5% Acid Resistant Brick for Acid Tank Excellent Anti-Corrosion

 The main component of acid-resistant brick is silica, which forms a large amount of mullite under high temperature roasting, which is a kind of material with high acid resistance. Because of its tight structure and low water absorption, acid-resistant brick can also be used at normal temperature. It is resistant to any concentration of alkaline medium, but it is not resistant to high temperature. The acid-resistant brick contains more than 70% of silica and is sintered. It is widely used in the chemical industry for acid-groove, acid well, acid storage and The acid-bearing impacted ground.

Acid-resistant bricks • Instructions for use

Widely used in petroleum, chemical, pharmaceutical, food, paper, fertilizer, pesticide, chemical fiber, textile, smelting, power plant and other industries, as well as anti-corrosion lining of towers, pools, tanks, tanks, and in sewage treatment engineering and open ground, etc. The workplace is designed to withstand acid and corrosion. Acid-resistant bricks are resistant to most media except hydrofluoric acid, hot phosphorus, and concentrated alkali. They have excellent anti-corrosion to wet chlorine brine, hydrochloric acid, sulfuric acid, nitric acid and other alkalis at room temperature. effect.

General epoxy resin, acid-resistant clay, acid-resistant cement paving, when paving, can be constructed according to the manufacturer's product manual; use oxalic acid to clean the concrete surface to achieve acid-base neutralization; industrial porcelain acid-resistant brick, the width of the joint is about 8 10mm, the seam depth is equal to the brick thickness to prevent leakage; after the paving is finished, the groove acid is used to wash the surface to help be more firm.

Acid-resistant bricks • production process

Common acid-resistant bricks for acid-resistant bricks include clay, quartz, potassium feldspar, and the like. The complete process of making acid-resistant bricks generally involves the following processes.

Abrasive: The raw materials of acid-resistant bricks, kaolin and porcelain stone, are ground, removed, mixed, and blended for production.

Billet: After pressing by press, the acid-resistant brick is made into the shape of acid-resistant brick needed to directly enter the drying furnace.

Glazing: According to the shape of the acid-resistant brick, there are different glazing methods. The way to ensure uniform dispersion of the glaze is an important point.

Casting: The formation of acid-resistant bricks is done by high-temperature firing in the kiln. The glaze on the surface of the acid-resistant bricks will undergo various chemical changes due to the difference in temperature.

Note on laying acid-proof tiles:

When lining the tiles, the bricks must be staggered, and the same layer of bricks should be staggered by 1/3~1/2 of the width of the bricks; the squeezing method should be used to lining the bricks, the ash joints should be full and compact, and the surface of the ash seams can be calendered at any time; The continuous lining height of the facade brick should be compatible with the gelling time of the cement to prevent the masonry from being deformed by pressure; the flat lining brick should be prevented from sliding; the thickness of the lining brick bonding layer is 6-8mm, and the slit width is 3-4mm.

Second, the acid-resistant brick paste substrate inspection and acceptance:

1. The brick slab is laid as a concrete foundation. These foundations must be inspected and accepted according to relevant regulations or standards before construction.

2. The surface of concrete must be firm, dense and flat, and there should be no defects such as sanding, cracks, honeycombs, and pockmarks.

3, the surface flatness is checked by a 2 meter ruler, the allowable gap should not be greater than 5mm, and the slope should meet the design requirements.

4. The concrete must be completely cured, and the water content within 20 mm of the surface should be less than 6%.

5. The construction surface must be clean and no residue such as floating ash, cement residue or steel bars should be left.

6. Pipes, casings, reserved holes, embedded parts, etc. that pass through the acid-resistant bricks should be completed before the bricks are laid.

Third, the surface treatment of acid-resistant brick paving:

In order to increase the bonding strength between the cement and the substrate, the construction surface of the substrate must be surface treated before construction to remove the acidification treatment. The curing curing substrate is used to check the base surface. The coating primer layer is applied to the construction of the brick lining lining quality inspection defect repair. Raw material quality inspection Brick board cleaning and drying clay preparation clay proportioning test brick board pre-processing brick board quality inspection oil, dust, etc., and vacuum cleaner with vacuum cleaner, dry clean compressed air or brush.

1. Surface treatment of concrete substrate:

Before the construction, the surface ash, cement slag and loose parts should be cleaned. The surface treatment of the base should be polished with a grinding wheel or wire brush, and then cleaned with a dry soft brush, compressed air or vacuum cleaner. If the moisture content of the concrete surface is greater than 6%, it should be dried at 40-60 ° C for three days and nights until the water content is less than 6%. For concrete surfaces greater than 0.50 mm cracks, honeycombs with diameters greater than 2 mm shall be repaired.

2, surface treatment of the isolation layer: the surface treatment of the isolation layer, the surface treatment method and grade should be selected according to the requirements of the surface of the various isolation layers.
