Low Porosity 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?: First: according to the environment to determine the acid resistant brick specifications.Second: inspects the good acid resisting brick performance.

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 acid resistant bricks used for chimney are usually made of custom-made trapezoidal acid proof bricks, and the physical and chemical indexes of acid resistant bricks need to be confirmed according to the chimney's actual emission. At this point, you can consult our kerei refractories.

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: What brand does acidproof ceramic tile ten big famous brands have?: What are the brand in the introduction of acid resistant ceramic ten brand-name before, we first introduce a black & decoration industry, Nalute diamond millstone. Now the decoration can not tile, cement and stone can be used to build silicon instead of diamond millstone tile, cement and building stone stone diamond silicon seamless and cast-in-situ seamless, no bacteria, diamond stone can release negative oxygen ions, make people relaxed and happy. Diamond millstone seamless cement and building stone by three silicon material composition: Nalute special cement mortar, defend a concrete seal curing agent and defend the wire concrete seal curing agent.

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: 98% acid tank cofferdam can use acid resistant brick?: Hydrogenation unit of hydrogen and high pressure and temperature, the system memory in the U2S and NH3, therefore, the corrosion problem of hydrogenation unit should also be emphasized, main methods to solve the corrosion problem of hydrogenation device is reasonable material, strengthen the surveillance and detection in use.

Q: Construction method of acid proof brick: QAGrassroots requirements: after the acceptance of the rubber lining, clean, keep clean and dry.Construction conditions: temperature at 15-30 Deg. C anti-corrosion construction is appropriate, the relative humidity is less than 80%, according to the temperature change adjust the dosage of curing agent, low temperature, humidity is too large, should be used to wet machine to adjust the temperature and humidity on the construction site.The construction of anticorrosive engineering is afraid of water and is afraid of drying.The preparation of mortar and glue is strictly carried out according to the proportion, and it is used up in the prescribed use time.

Q: The difference between polished tiles and glazed tiles?: Just because of the surface layer, so the pattern will slowly fade, it looks very old, but the brick does not have this problem, the brick on the market, some does not completely block brick has a pattern, just by the superposition technique, will have almost half the above pattern.
