calcium hydroxide
Description
calcium hydroxide is a kind of grey powder. It consists of calcium oxides, silicon dioxide, ferric oxide and little other ingredients. When mixed with appropriate water and poured into the pre-drilled holes, it will start to expand after half an hour, the expanisve power is increasing as time goes on. It can get 100-123 Mpa expansive power after some hours. Generally, the rock or concrete belongs brittle material, their tensile strength are far less than the compressive strength (for the tensile strength, rock is 1.96-30Mpa while concrete is 1.5-4.0 Mpa, they are equal to 1/10-1/20 of their compressive strength). Therefore, reasonable hole design can easily crack the rock and concrete or reinfored concrete by our BREAK-AG. As usal, it can crack the materials in around 2-24 hours. It is soundless, non-explosive, no noise, no vibration, no flying rock during the process of demolition.
Application
1. Mainly adjust acid waste water pH value, widely used for electroplate, chemical industry, circuit board, pickling, printing & dyeing and paper making, industries waste water treatment.
2. Used to remove phosphate,most of the heavy metal and ammonia nitrogen etc.
3. Used for tanning and mining industry etc.
