    Core tips: the harm of paint: 1 Teratogenesis a large number of research data confirmed that the toxic substances left in house decoration can cause birth deformity 2 The benzene series compounds (benzene, toluene, xylene) which are widely used in septic paint and decoration glue will damage the hematopoietic function, cause hematological diseases, cause cancer and induce leukemia 3 TDI, an important component of allergic polyester paint, is listed as a highly hazardous substance in the national standard gb5044-85 Induced skin rash, dizziness, decreased immunity, respiratory tract damage, asthma and other allergic reactions 4 Brain toxicity is manifested as nervous system damage Long term accumulation of solvent (commonly known as thinner) in paint Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Paint Home News: the harm of paint: 1 Teratogenesis a large number of research data confirmed that the toxic substances left in house decoration can cause birth defects 2 The benzene series compounds (benzene, toluene, xylene) which are widely used in septic paint and decoration glue will damage the hematopoietic function, cause hematological diseases, cause cancer and induce leukemia 3 TDI, an important component of allergic polyester paint, is listed as a highly hazardous substance in the national standard gb5044-85 Induced skin rash, dizziness, decreased immunity, respiratory tract damage, asthma and other allergic reactions 4 Brain toxicity is manifested as nervous system damage The solvent in the paint (commonly known as thinner) accumulates in the central nervous system for a long time, leading to brain cell damage, causing chronic solvent poisoning syndrome, neurological mental disorders, etc Reduce children's intelligence What's the harm of paint? The gas of paint is mainly organic solvent For the toxicity of organic solvent, please refer to the following materials: 1 The toxicity of organic solvent will cause chronic poisoning if people inhale the vapor of organic solvent for a long time However, if they are exposed to the vapor of high concentration organic solvent for a short time, they will also have the risk of acute poisoning In industrial hygiene, the harm of organic solvents to human body is closely related to the volatility of solvents At room temperature, low volatile solvents are not easy to cause danger in the air Other hazards related to human body include fat solubility of solvent, reactivity, impurity content, way and way of human absorption, metabolic rate, accumulation, individual feeling and sensitivity, length of exposure time, etc 2 Ways of harm to human body (1) harm caused by skin contact: organic solvent vapor will stimulate eye mucous membrane and make people cry; contact with skin will dissolve skin oil and penetrate into tissue, interfere with physiological function and dehydration; and because skin is dry and cracked, it will infect dirt and bacteria The cuticle dissolves on the surface of the skin, causing cutinization of the epidermis, and stimulating the epidermis to cause redness, swelling and air bubbles The solvent penetrates into human body and destroys blood cells and bone marrow (2) Harm caused by respiratory organs: when organic solvent vapor is inhaled into human body through respiratory organs, people often have anesthetic effect After inhalation, most of the steam reaches the lungs through the enterprise management, and then it is transmitted to other organs through blood or lymph, resulting in varying degrees of poisoning Because the area of alveoli in human body is more than ten times of the surface area, and the speed of blood circulation diffusion is very fast, it often produces significant toxicity to respiratory tract, nervous system, lung, kidney, blood and hematopoietic system The poisoning phenomenon caused by inherent organic solvent through respiratory organs is the most important (3) Harm caused by digestive organs: the main cause of organic solvents through digestive tract is eating, smoking or touching the mouth with fingers in the place where solvent vapor is polluted The harm caused by organic solvents is first suffered by the mouth, entering the esophagus and gastrointestinal tract, causing nausea and vomiting, and then harming other organs from digestive system 3 The general symptoms of organic solvent poisoning are headache, fatigue, anorexia, dizziness, etc High concentration of acute poisoning suppresses the central nervous system, makes people lose consciousness, and produces anesthesia phenomenon At the initial stage, it causes excitement, lethargy, headache, dizziness, tiredness, loss of appetite, consciousness disappearance, etc.; while low concentration of steam causes chronic poisoning, which affects the hematopoietic system such as platelets, red blood cells, noses, gums and subcutaneous tissue bleeding, resulting in human anemia General organic solvents have the following physiological effects on human body: (1) damage to nervous system; (2) damage to liver function; (3) damage to kidney function; (4) damage to hematopoietic system; (5) irritation to mucous membrane and skin; 3) ways to reduce or reduce paint damage: Workers who have been exposed to paint for a long time shall wear masks and gloves during construction to avoid direct contact between paint and skin; it is not suitable to drink white wine, because alcohol will prolong its staying time in the body, which is extremely harmful to health; air circulation shall be maintained in the workplace to reduce its concentration in the air; usually, they shall eat more food with high vitamin content and drink more boiled water Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
