Standard Low Density Mullite Brick

Q: How to clean the acid brick surface dirt?: Wash the bricks with a mixture of soap and a little ammonia and turpentine, and make the bricks more lustrous.

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: What is anticorrosive floor tile?: The above construction method is simple, and the normal paving tiles are the same. It is convenient to add 2-3mm cross micelles when leaving gaps.

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 acid proof brick alkali resistant?: Absolutely neutral materials do not react with acids, nor react with alkalis, and do not react at higher pressures and temperatures. Of course, this condition is not endless.

Q: Is there a construction picture for the acid proof brick in the pickle pond?: As the base layer, bonding layer and acid brick itself thermal expansion, cold shrinkage coefficient is very different, in 1-2 years of hot and cold tension failure, too dense paving easily lead to acid brick swelling, fracture and other issues

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?: Some of the plants in the market are directly drawn from the local ordinary clay and fired directly into tiles. They also impact the market at low prices, and the consequences can be imagined.

Q: Do you want to leave the seam on the acid proof brick? What is the width of the seam?: Leave the seam is reserved for a certain expansion space, to prevent summer heat when the brick bulge, affect the use of. The crown of acid proof brick if the proposal is pointing the slit width is generally between 8-10mm; extrusion seam words in 5mm can be.

Q: Construction method of acid proof brick: Construction methodLining adhesive layer, mortar protection layer: lining carbon brick before, in the bottom board first put a layer of delta =3mm cement whole surface layer, in order to protect the lining layer and avoid mortar joint layer appear blind seam, curing at normal temperature after masonry.Positioning, layout and layout: according to the bottom of the groove size, first play the central cross line, then positioning, line, according to the line for typesetting, painting, cutting and numbering.Lining procedures: masonry procedures from low to high, the first base, the rear wall, the Yin angle, the facade to suppress the plane, Yang Kok plane cover the facade.Masonry method: the bottom and wall are all made by squeezing, kneading and extruding, and they are made by line by line, layer by layer, block by block.The prepared mortar evenly scraping on the three surfaces of carbon brick (i.e., on the back end, and then squeeze (side), rubber hammer) is dense, the ash seam and the combined layer clay full, squeeze out excess clay to eradicate. The surface shall be made of flat and vertical, rows and rows, and the seams between floors and layers shall be staggered.
