Three-dimensional model vinyl chloride chloroethylene Vinyl chloride, also known as vinyl chloride (Vinyl chloride) is an important chemical used in polymer monomer, ethylene or acetylene can be obtained. Is a colorless, easily liquefied gases, boiling point -13.9 ℃, the critical temperature of 142 ℃, the critical pressure of 5.22MPa. Vinyl chloride is a toxic substances, liver, and long-term inhalation and exposure to vinyl chloride related. It is the formation of explosive mixtures with air, explosive limits of 4% ~ 22% (volume), under pressure more explosions, storage and transportation must pay attention and nitrogen sealed airtight container, and should add a small amount of inhibitor.

toxicity: acute toxicity expressed as narcotic effect; Long-term exposure can cause vinyl chloride disease. Acute poisoning: mild poisoning, the patient developed dizziness, chest tightness, drowsiness, staggering gait, etc.; severe poisoning can occur coma, convulsions and even death. Skin contact with liquid vinyl chloride can cause erythema, edema, or necrosis. Chronic poisoning: the performance of the neurasthenic syndrome, hepatomegaly, abnormal liver function, digestive dysfunction, Raynaud "s phenomenon and acral osteolytic disease. The skin may appear dry, chapped, scaling, eczema and so on. Irritant: No Data Allergenicity: no information Mutagenicity: No information Teratogenicity: No information Carcinogenicity: This product carcinogens, can cause liver angiosarcoma Aid measures Contact with the skin: immediately stripped of contaminated clothing, use soap and water thoroughly washed skin. Medical treatment. Eye contact: Did eyelid, mobile or saline irrigation water. Medical treatment. Inhalation: rapidly from the scene to fresh air. To maintain airway patency. If breathing is difficult, give oxygen. If breathing stops, artificial respiration immediately. Medical treatment. Ingestion: Not available HANDLING AND STORAGE Op eration Note: closed operation, fully ventilated. The operator must go through specialized training, strict compliance with operating procedures. Proposed operators wear filter respirators (half-mask), wearing protective chemical safety glasses, wear anti-static overalls, wearing gloves against chemicals. Away from fire, heat source, smoking is prohibited in the workplace. Use explosion-proof ventilation systems and equipment. To prevent gas leakage to the workplace air. Avoid contact with
