Low Porosity Brick

Q: How to clean the acid brick surface dirt?: Daily cleaning of bricks can be done with detergent, soap and other cleaning.

Q: The acid resistance is 99.4%. Is this acid resistant brick very bad?: Bending strength, 39.2., water absorption, 0.5-2.0., quench, hot, 100du, cycle without cracks, peeling, etc. the quality of acid resistant tiles is mainly reflected in water absorption, the lower the water absorption, the higher the acid resistance

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: What is a thermal insulation castable?: Good workability, strong adhesive force, initial setting time and construction of long operation time, fast increase of strength and impermeability, without acid treatment, easy to ensure masonry mortar joint compacting full, can significantly improve the corrosion resistance of chimney lining wall tightness, integrity and lining, is ideal for cementing materials of high chimney, high temperature flue and duct lining, can also be used in petroleum, chemical industry, non-ferrous metallurgical industries such as acid pool, such as acid tank engineering. Acid proof brick, acid proof daub fabric acid proof brick, acid proof daub fabric is developed by this factory can be in power plant boiler funnel of special refractory material, it has the acid corrosion resistance, temperature resistance, thermal stability and convenient construction.

Q: The difference between acid and heat resistant lightweight castables and acid resisting bricks: Acid resistant bricks can be customized according to different environments, and resist acid and alkali brick materials of various acids and bases. And pouring materials basically uniform formula, even if a slight adjustment can not solve the strong acid, strong alkali use environment.Acid resistant bricks can be factory mass customization, the cost is slightly lower, while the casting materials need on-site construction, the cost is slightly higher.

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: 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 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.

Q: Cleaning metal surface rust stain, is it better to weld sulphuric acid or nitric acid?: The principle of treating oxide skin with salt bath method has been introduced in the second article. When the oxide in the oxide scale of the metal surface has chemical reaction, because the expansion coefficient of the oxide layer and the metal matrix is different, the rust scale and the metal matrix can separate and fall off.

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.
