- 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:Acid resistant brick lining, engineering scaffolding, how to take?
- Material preparation: the anti-corrosion materials used in this project are stored in the appropriate warehouse (site), and the incoming materials are tested to comply with the requirements of the HGJ229-91 specification. Equipment preparation: cutting machine, mixer, grinder, trolley, cement plate, rope
- 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:Is acid proof brick alkali resistant?
- Acid resistant brick is generally acidic or neutral, it itself will not react with acidic materials, but neutral materials can be divided into neutral partial acid, neutral partial alkali and absolutely neutral (such as silicon carbide, etc.).
- Q:How to clean the acid brick surface dirt?
- Daily cleaning of bricks can be done with detergent, soap and other cleaning.
- Q:Does the chimney have high acid resistance?
- The chimney particles and gases, mostly coal tar products, material acidic, therefore, take good acid resistance, acid proof brick, Grouts also used potassium silicate clay acid is preferred. If it is an ordinary high alumina brick, it does not meet the requirements of acid resistance, and only the chimney lined with acid resistant bricks.
- 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:Acid proof brick, acid resistant porcelain in the paste process with no seam
- 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: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:How much is one square meter of acidproof tile?
- Acid proof brick is made of quartz, feldspar, clay as the main raw material, acid resistant materials by high temperature firing, with acid of high, low water absorption, is not easy to be oxidized at room temperature, is not easy to be medium pollution characteristics.
