Trichloroethylene (Trichloroethylene)

Trichloroethylene – it is a transparent, oily and volatile liquid. Trichloroethylene has a smell of chloroform, sweet and burning taste. In water it is not soluble. Under the influence of light and air trichloroethylene decomposes into phosgene and halogen-containing acid. In order to stabilize the trichlorethylene to him added stabilizers in different concentrations.

He trichloroethylene relates to flame retardant chemicals.
Vapor is heavier than air. As a result of spillage, mixing, etc to form electrostatic charges.

Upon contact with hot surfaces or flames this substance decomposes to form toxic and corrosive fumes (phosgene, hydrogen chloride). The substance decomposes upon contact with strong alkalies with the formation of dichloroacetylene that increases the fire hazard. Reacts violently with metal powders such as, magnesium, aluminum, titanium, and barium. Slowly decomposed by light in the presence of moisture with formation of corrosive hydrochloric acid.

Substance irritating to eyes and skin. Swallowing the liquid may cause aspiration into the lungs with risk of chemical pneumonia. The substance may to have an effect on the Central nervous system, leading to respiratory failure. Exposure can cause clouding of consciousness.

Re or prolonged contact with skin may cause dermatitis. The substance may have effect on the Central nervous system, leading to memory loss. Substance can have an effect on the liver and kidneys. The substance is probably carcinogenic for a human being.

Trichloroethylene is used in the manufacture of refrigerants, various acids, herbicides. Widely trichloroethylene used as solvent dyes, bitumen, resins, phosphorus and other chemical compounds and substances, and also as a means of degreasing metal products.

Degreasing with trichloroethylene can to put steel, copper, Nickel, their alloys, and a number of other metals as well as components equipment, brazed and tin-silver solders. You should avoid processing of aluminium, magnesium and their alloys, as this happen adverse reactions, accompanied by release of large amount of heat which leads to decomposition products with the formation of toxic compounds.

Degreasing of parts organic solvents is carried out by immersion in a vapor or spray method. In the last case is most fully remove a variety of impurities, including bad soluble, as the chemical action of a solvent combined with mechanical impacts striking the surface of parts of the jet. The most effective results are achieved in a sequential degreasing liquid solvent and then it pairs or blasting. To implement such processes, especially when using trichloroethylene and freon-113, must use special installation ensure sealing of the working area and create the necessary working conditions.
