Product Description

Chemical name: Lime
Sub sub type: CaO
Sex: white or gray block or particles, easy to absorb moisture and carbon dioxide in the air. Easy water digestion, formation of calcium hydroxide, and release a lot of heat.
Use: used as fillers and desiccant, all kinds of waste water purification, but also for building materials, metallurgical flux, of calcium compounds and Gou of caustic soda in the main raw material.
Package: composite plastic woven bag *5KG/ bag
Calcium oxide because in many articles repeatedly mentioned, and now ignored. And then look at some of their uses. A, calcium oxide in shrimp pond first, powder for a long time in the air exposure will absorb carbon dioxide into powder calcium carbonate (limestone) of the main ingredients, not to the pond sterilization effect. Because this is the best use of lime to buy now, and select a block of light, no impurities as well. If a plastic bag with a plastic bag is used for the first time, it is kept in a plastic bag. Second, the raw lime and nitrogen fertilizer application at the same time. Lime water meets generated a lot of OH -, NH4 + + OH = NH3, H2O equilibrium to the right, the ammonia content high easy to cause fish ammonia poisoning. Similarly, ammonia nitrogen content in the water more than 1.2 mg / L, also should not be placed with lime. The application of ammonium nitrogen fertilizer after a week before the use of lime, do not mix. Third, lime to join the slurry after taking advantage of the heat sprinkling and avoid the debris into the pool, in order to avoid the fish in the moat while eating death, but not the whole lime thrown into the pool for water disinfection. Soluble in water, generating calcium hydroxide, heat. At room temperature was white amorphous powder, containing impurities when gray or pale yellow, with moisture absorption. Can also be used for steel, pesticide, medicine and metallic iron, fertilizer, tanning, prepared calcium hydroxide, ammonia laboratory drying and dehydration of alcohol. Strong corrosion resistance.
