Q:What is a thermal insulation castable?
The thermal insulation castable is the castable with lower bulk density, the basic body is about 1.5. The castable contains many pores, low volume density, small thermal conductivity and good heat preservation effect.
Q:What is acidproof ceramic tile?
Ceramic tile is acid with quartz and 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.
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: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:Consult: water treatment room anticorrosive usable granite and acid resisting brick, these two kinds of material what?
You can look at RZG/, the proportion of Rizhao garnet, high hardness, good toughness, wear resistance, acid and alkali resistance, flushing, moderate porosity, in the field of sewage treatment is widely used as a high density filter (heavy medium filter).
Q:The acid resistance is 99.4%. Is this acid resistant brick very bad?
Bending strength, 39.2., water absorption, 0.5-2.0., quench, hot, 100du, cycle without cracks, peeling, etc. the quality of acid resistant tiles is mainly reflected in water absorption, the lower the water absorption, the higher the acid resistance
Q:Acid proof brick, acid resistant porcelain in the paste process with no seam
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: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: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: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
