How can acid proof cement be used?
In the use of acid resistant cement, it is necessary to add hardener sodium fluosilicate, it will be mixed with acid resistant cement evenly; preferably 2 times screening.
When in use should be mixed after the finished product into the container, after adding water glass solution, mixing uniformly rapidly; usually with less than one hundred kilograms of stir, each tune into the product to be used within 50 minutes.
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.
Acid resistant cement should be hardened at temperatures above 15 degrees Celsius, and maintained in the air for about 10-20 days, the winter temperature is low, time is long, as far as possible not suitable for use.
Before construction, metal equipment should be rust removal, decontamination, etc., brick structure should be washed clean, acid resistant cement surface should be first neutralized by acid, washed with water, and then heating drying, generally require less than 4% moisture.
