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: 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: 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: How can acid proof cement be used?: After drying to curing acidification, the basic method is to brush the surface of 40% sulfuric acid, once every 4 hours, every time the crystal precipitation should be removed in the next coating, until no crystallization, acid treatment after use.

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: 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: 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: 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.

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.
