4.Useage
Dichloromethane has the advantages of strong dissolving ability and low toxicity. It is widely used in the production of safe film film, polycarbonate, and the rest as paint solvent, metal degreasing agent, aerosol spray agent, polyurethane foaming agent, mold release agent and paint removal agent.
Dichloromethane, a colorless liquid, is used as a reaction medium in the pharmaceutical industry to prepare ampicillin, oxypicillin and avanamycin.
It is also used as foaming agent and metal cleaning agent in film production, petroleum dewaxing solvent, aerosol propellant, organic synthetic extraction agent, polyurethane and other foam plastics.
Dichloromethane is mainly used in film production and medicine in China.
Among them, the consumption of film production accounts for 50% of the total consumption, the consumption of medicine accounts for 20%, the consumption of cleaning agent and chemical industry accounts for 20%, and the consumption of other aspects accounts for 10%.
Dichloromethane is also used as a refrigerant carrier in industrial refrigeration systems, but it is very harmful, producing highly toxic phosphogas in contact with open or hot objects.
Moisture in the air can hydrolyze to form a trace of hydrogen chloride, light can also promote hydrolysis and increase the corrosion of metals.
Used for grain fumigation and refrigeration of low pressure freezers and air conditioning units.
Used as an auxiliary foaming agent in the production of polyether urane foam and as a foaming agent for extruding polysulfone foam.
Methylene chloride is also used to make decaffeinated coffee.
Coffee is first boiled to dissolve the caffeine and float it on the surface, then dichloromethane is used to remove the caffeine.
5. Company profile
Qingdao Hisea Chem Co., Ltd is a famous chemical manufacture since 1996, located in Chemical Logistics Park of Qingdao port which is only 30 kilometers from the Qingdao port, and the traffic is very convenient.
Based on the oil refining chemical plant of CNPC and Sinopec which distributed around of China, we product Glacial acetic acid, Formic acid, Nitric acid and hydrogen peroxide, and we produce sodium hydroxide, potassium hydroxide, sodium sulfide, potassium sulfate based on salt, potassium, magnesium, coal resources from the lop nurand the Qinghai lake. Reduplicating distillation the acids and the solvents and improving the product purity is to reach each field application, textile, reagent and medical level etc. It is our top advantage to provide the high purity of products and make customized production according to the customer's requirements. We have our own sub-assembly factory to better meet customer needs.
Nowadays, we have exported to 70 countries around of the world and establish firm trade relationship. It would be our honor if you can contact with us and cooperate with us.

Notice
Health hazard: the goods have anesthetic effect, the main damage of the central nervous and respiratory system human exposure is the main way of the suction has been measured, in the production of indoor environment, when using dichloromethane as varnish remover, there is a high concentration of methylene chloride in the general population through the surrounding air and drinking water and food contact, much lower doses it is estimated that in the world of the methylene chloride production, about 80% is released into the atmosphere, but due to the fast rate of the compound photolysis, make it impossible to accumulate in the atmosphere the initial degradation products of phosgene and carbon monoxide, and then into carbon dioxide and hydrochloric acid When dichloromethane is present in surface water, most of it will be vaporized in the presence of oxygen, and is prone to biodegradation, so bioaccumulation seems unlikely but its behavior in soil has yet to be determined
