Q:What is acidproof brick?: The main component of acid resistant brick is silica, and Hao Ran acid resistant bricks are made of imported raw materials and imported color materials by high temperature firing.

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: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:What is anticorrosive floor tile?: Only 30mm thick slabs in the market are not above, the most is 20mm thick slabs, the glass ceramics (that is on the market only Guanzhu, the new source, Monalisa and Baird only) are acid and alkali. Square brick (quite cheap)

Q:How much is one square meter of acidproof tile?: Acid resistant brick: resistance to pressure, corrosion resistance, easy to clean, acid and alkali; acid resistant tile prices generally around 40 yuan a square meter!

Q:Is acid proof brick alkali resistant?: Acid material must not be alkali resistant,Neutral acid material is not alkali resistantNeutral alkaline material at the appropriate temperature and pressure can be alkali resistant, but not acid, but the reaction is slow.

Q:Is it necessary to use sulphate resisting cement in alkaline areas?: Acid resisting cement is a kind of powdery material made of high acid resistant material and hardening agent, which are mixed or mixed separately according to proper proportion.

Q:The acid resistance is 99.4%. Is this acid resistant brick very bad?: Do not recommend you buy the acid resistance of substandard tile, tile acid refers to the acid resistance of 99.8 according to the national standard

Q:Is there a construction picture for the acid proof brick in the pickle pond?: Acid resistant brick, acid resistant ceramic tile in the shop, many users only pay attention to beauty, and use not leave seam shop, or shop too tight, too close, easy to leave hidden dangers for the future.

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.
