Acid-proof Spray Coatings
The acid-proof spray coatings are prepared from acid-proof aggregates and powder serving as main raw materials, water glass or silicate cement serving as a bonding agent and additives. The acid-proof spray coatings are mainly used for steel plate protection layers of spherical caps of hot air furnaces and various chimneys, and the better effects are achieved. Moreover, the coatings can also be used for pouring construction, so it is also called acid-proof pouring materials.
1. High compressive strength:
Because the high-pressure gas machinery is used for spray coating, the repeated impact and pressing are made in the spraying process, the compactness is high, and the compressive strength is also high after final set;
2. Hard material:
Having excellent wearing resistance, which is more than 3 times higher than that of the common concrete;
3. Stable performance:
With high anti-corrosion property, it can resist the corrosion of various organic acid and inorganic acid gases as well as the corrosion of oxidizing acids and high-concentration acids.
Wearing resistance and corrosion resistance of wearing parts such as sintering machines, air boxes, branch pipes, etc. in steel and iron, nonferrous metallurgy and non-metallic mineral metallurgy.
