The main ingredients and the use of attention to the matter
Paint materials contain a variety of solvents Benzene, xylene, nitro paint in the diluent Ethanol, butanol, etc. are also toxic in the construction of volatile solvent vapor, high concentrations of human nerves have a more serious stimulation and harm. Low concentrations also have headaches, nausea, fatigue and abdominal pain and so on. In the long-term exposure will cause loss of appetite, damage to the hematopoietic system, the occurrence of chronic poisoning. But as long as the attention to strengthen the protection, try to prevent paint contact with the skin, if possible to more window ventilation and `let the indoor air distribution. I know a lot of life in the paint of the old master, although older but very healthy, more live to ninety birthday, another eighty one year old this year still ears, there are several have six or seven years old, Disease-free disaster, so as long as the attention to protect themselves, you can ensure safety. After the completion of the construction and use of all the opportunities for a lot of window ventilation ventilation is it.
In paint paints are often exposed to some toxic effects of the compounds, these compounds will cause some environmental and human health toxic effects. Now the common toxic compounds in paint coatings are as follows: Toluene, xylene: in the solvent classification is a moderate toxic solvent, the human body has anesthesia, stimulating effect, high concentration of toxic effects on the nervous system, but residual in the human body Low toxicity, generally can be excluded by metabolism. The maximum allowable concentration in air is 100mg / m3. Long-term exposure to toluene, xylene people should not drink liquor, but should not drink excessive high degree of liquor, because alcohol will extend its retention time in the body, the health is extremely unfavorable. Workplace should keep air flowing to reduce its concentration in the air According to the latest research data show that toluene, xylene into the atmosphere will produce a certain photochemical reaction, the ozone layer has a certain destructive effect. Benzene: a highly toxic solvent, a small amount of inhalation will cause long-term damage to the human body. Benzene in the nervous system and bone marrow accumulation, the nervous system and hematopoietic tissue damage, causing blood leukocytes, platelet count decreased, long-term exposure can cause leukemia. Ethylene glycol ether solvent: glycol ether solvent in the body after the metabolism will form a highly toxic compounds, the human blood circulation system and the nervous system caused permanent damage, long-term exposure to high concentrations of glycol ethers Solvent can cause cancer. In addition, glycol ethers can cause permanent damage to the female reproductive system, resulting in female infertility.
Pungent taste is mainly from formaldehyde, benzene, TVOC and other pollutants emit out, their hazards are: formaldehyde is a colorless and soluble irritant gas. Particleboard, MDF, plywood and other man-made sheet, adhesive and wallpaper is the main source of formaldehyde in the air, the release period of up to 3 to 15 years. Can be absorbed by the respiratory tract, formaldehyde on the human body with a long-term hazards, latent, hidden characteristics. Long-term inhalation of formaldehyde can cause nasopharyngeal carcinoma, throat cancer and other serious diseases. Benzene is a colorless, with a special aroma of gas. Glues, paints, paints and adhesives are the main source of benzene in the air. Benzene and benzene by the body after inhalation, there may be central nervous system anesthesia; can inhibit human hematopoietic function, so that red blood cells, white blood cells, thrombocytopenia, aplastic anemia increased; also lead to abnormal menstruation, fetal congenital Defects and so on. TVOC total volatile organic compounds, VOC, Votatile Organic Compound abbreviation, VOC in the indoor air as a heterogeneous pollutants, because of their separate concentration is low, but the type, generally not one by one, respectively, to TVOC said its total. TVOC includes benzene, toluene, butyl acetate, ethylbenzene, p-xylene, styrene, o-xylene, undecane and the like. Interior construction and decoration materials are the main source of TVOC in the air. Studies have shown that even if the indoor air in a single VOC content is lower than its limit, but a variety of VOC mixed and its interaction, so that the damage intensity increases. TVOC showed toxicity, irritation, can cause the body immune disorders, affecting the central nervous system function, dizziness, headache, drowsiness, weakness, chest tightness and other symptoms, may also affect the digestive system, loss of appetite, nausea, etc. Damage the liver and hematopoietic system, and even cause death.
