Calcium hydroxide (ash) is a kind of white powder, chemical formula Ca (OH) 2, commonly known as slaked lime, hydrated lime. After adding water, with two layers, the upper water solution called clarifying lime water, the lower suspension called milk of lime or lime slurry. The supernatant can clarify lime water test for carbon dioxide, lower turbid liquid milk of lime is a kind of building material. Calcium hydroxide is a kind of white powder, slightly soluble in water. Calcium hydroxide is an alkali alkali is two yuan, the universal, is a kind of strong base, on the skin, the fabric of corrosion. Calcium hydroxide is widely used in industry. White powder, produced by lime and water, it is called the saturated water solution of the lime water. Is commonly used building materials, also used as a fungicide and chemical raw materials, etc..
Calcium hydroxide is widely used in production and life:
1, calcium hydroxide in coating application, calcium hydroxide in the construction industry called sierozem and with its delicate, white, high calcium and extensive application in construction industry in coatings, powder putty and putty paste, calcium hydroxide in the air and carbon dioxide generated in the reaction, white and hard to coagulation, bricklaying with slaked lime and a mixture of sand, lime paint the walls.
In 2, lime trees on besmear containing sulfur powder, etc., can protect trees, prevent frostbite, and prevent insect eggs;
3, the preparation of tabia; agriculture with milk of lime and copper sulfate solution prepared with bactericidal effect, can be used in the production of calcium carbonate, epichlorohydrin, epoxy propane, bleaching powder, bleaching powder concentrate, disinfectants, check acid, astringent, water softener, soil acid preventing agent, hair removal agent, buffer, neutralizing agent, curing agent and drug; used in rubber and petroleum chemical additives, such as the oil industry in the lubricating oil, to prevent coking, sludge deposition, and anti-corrosion.
4, Bordeaux as pesticides. Change the soil pH: the amount of lime into the soil, can neutralize the acid, improve acid soil, easy to crop survival; 4, the production of food additives, sodium hydroxide, production of bleaching powder.
Corrosive
This product has a strong corrosive, and its dust or suspended droplets on the mucous membrane irritation, although not as good as the weight of sodium hydroxide, but also can cause sneezing and coughing, and alkali can make the fat emulsion, from the skin to absorb moisture, dissolved protein, stimulation and corrosion tissue. Inhalation of lime dust may cause pneumonia. Inhalation of dust, respirable water vapor, codeine, over the thorax at coated with mustard paste; when the fall into the eyes, available water rinsed as soon as possible, rinse and then 5% ammonium chloride solution or 0.01%CaNa-EDTA solution, then the 0.5% dicaine solution to drop in. Work should pay attention to the protection of respiratory organs, wearing a dust proof fiber system of work clothes, gloves, sealed dust glasses, and coated with oil ointment to prevent dust inhalation.
Products according to customer requirements in the packaging can be used in a bag of 25 kg, can also be used in the form of tons of bags. Products in the raw material procurement, production and processing, warehousing and storage process have full-time laboratory personnel to ensure that quality is guaranteed.
