Standard Low Density Mullite Brick

Q: The acid resistance is 99.4%. Is this acid resistant brick very bad?: Now almost no manufacturer of acid resistance is fully up to standard, 99.4% is already good, not acid brick bad, daub is broken, daub acid resistance is lower 90%, so don't kink, rest assured to use!

Q: What are the standard specifications for acid resisting bricks?: Because of the different acid and alkali environment, the acid resisting ceramic tile has different requirements on the degree of acid and alkali, so it is necessary to make the price reasonable at the time of construction,

Q: What is acid proof brick: The main component of acid resistant ceramic tile is silica, which forms a large amount of andalusite under high temperature calcination, which is a kind of material with high acid resistance. The acid proof brick structure, low water absorption, so at room temperature are resistant to alkaline medium at any concentration, but not resistant to high temperature molten alkali. Acid resisting brick contains more than 70% silicon dioxide, and is made by sintering. It is used in acid chemical ditch, acid well, acid storage storehouse and acid loaded big impact ground.

Q: Does the chimney have high acid resistance?: The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred. If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.

Q: Is it necessary to use sulphate resisting cement in alkaline areas?: 1. acid can be applied in chemical industry, petroleum, metallurgy, machinery, textile, papermaking, sugar and other industrial equipment in construction engineering, the floor in the equipment foundation, acid corrosion and acid storage tank, chimney lining workshop, building waste and gaseous acid corrosion, can be prepared by acid resistant clay masonry brick acid and board; can be mixed with acid and coarse aggregate (gravel), fine aggregate (sand) acid and preparation of acid resistant concrete.2. can not be used by hydrofluoric acid, fluosilicate, 300 degrees above phosphoric acid and advanced fatty acids and oleic acid, palmitic acid, and alkaline salt erosion engineering. When used in the food industry, sodium fluoride in sodium fluosilicate should be tested to prove that it is not harmful to humans.

Q: Which acid proof tile factory is reliable in quality?: We all know that the main component of acid resistant ceramic which is silica, liangdun acid resistant ceramic material is used by Shanxi local quartz stone, containing a large number of silicon content, acid resistant tiles can thus produced corrosion.

Q: What is acidproof brick?: Hao Ran acid tile brick structure compact, low water absorption rate, the pH of the medium can be any concentration, with excellent corrosion resistance. And the set pressure, wear resistance, anti permeability, easy cleaning, acid and alkali in one, with excellent performance is widely used in petroleum chemical industry, metallurgy, electric power, chemical, papermaking, pharmaceutical, chemical, food, dairy, juice, electroplating and the tower, tank, tank, tank anti-corrosion engineering, and work in the underground sewers the open ground and other places play an important role.

Q: Do you want to leave the seam on the acid proof brick? What is the width of the seam?: It is necessary to leave the seam when resisting the acid brick. Acid resistant bricks are corrosion resistant ceramic tiles, and all ceramic tiles have a certain expansion ratio, and there is a phenomenon of expansion and contraction.

Q: Construction method of acid proof brick: Construction preparationFamiliar with drawings, specifications, technical disclosure, do a good job of the handover process.Material preparation: the anti-corrosion materials used in this project are stored in the appropriate warehouse (site), and the incoming materials are tested to comply with the requirements of the HGJ229-91 specification.Equipment preparation: cutting machine, mixer, grinder, trolley, cement plate, rope, hose, shovel, wipe, steel scraper, rubber hammer, steel wire brush, brush, putty knife, the level of scale, by foot, rope, wire, small pendant, Jue measuring cup, scales, tarps, ventilation and lighting equipment.

Q: What is acid proof tile, acidproof ceramic tile brand introduction?: Among them, the detection of acidity and alkalinity is one of them. The state has relevant standards.Among them, the inspection standard of glazed tiles is different from that of polished tiles.
