How to choose acid resistant bricks

The corrosion-resistant materials made of Zhongguang acid resistant ceramic tiles through high-temperature oxidation and decomposition have the characteristics of high pH resistance, low water absorption and not easy to oxidize at room temperature
In addition, the acid resistant ceramic tiles formed by them are not easy to be polluted by media
So how to choose acid resistant brick?
 
1
Listen
Flick with your fingers and the sound is crisp and pleasant, which indicates that the porcelain degree is very high and the quality is good
If the sound is dull and muddy, it means that the quality of acid resistant ceramic tiles will also be poor

2
Look
The color of acid resistant ceramic tile must be uniform, the surface finish and flatness should be good, and there should be no concave convex feeling
The surrounding edges and corners should be neat, and there should be no defects, missing edges and corners
It can be taken up like a carpenter and aligned with a line to see with the naked eye, otherwise it will affect the construction, even if it can be used for decoration, The gap between ceramic tiles is relatively large and is not suitable for use

Dripping
Turn the acid resistant ceramic tile upside down, with the back facing up, and drop a drop of water in the middle to see the penetration speed of water on the back of the brick
The faster the speed, the lower the density of the acid resistant ceramic tile, the lower the quality
The slower the water absorption, the higher the density and good quality of the acid resistant ceramic tile
