Coating knowledge: environmental protection knowledge of wall paint

Core tips: China new coatings news: environmental protection index 1: volatile organic compounds (VOC) content At present, the compulsory standard is implemented in our country, that is, VOC ≤ 120g / L There are three types of VOC effects on human body: odor and sensory effects, mucosal irritation and other systemic toxicity Some VOCs have been shown to be carcinogens or suspected carcinogens Environmental protection index 2: formaldehyde content Now the compulsory standard value is ≤ 100mg / kg Formaldehyde itself is highly toxic and has a strong coagulation effect on protein, which can 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: China new paint news: environmental protection index 1: volatile organic compounds (VOC) content At present, the compulsory standard is implemented in our country, that is, VOC ≤ 120g / L There are three types of VOC effects on human body: odor and sensory effects, mucosal irritation and other systemic toxicity Some VOCs have been shown to be carcinogens or suspected carcinogens Environmental protection index 2: formaldehyde content Now the compulsory standard value is ≤ 100mg / kg Formaldehyde itself is highly toxic and has a strong coagulation effect on protein It can combine with amino and hydroxyl groups of nucleic acid to denature it It can block the action of stomach enzyme and pancreatin, thus affecting metabolism Its steam has carcinogenic effect on rodents Environmental protection index 3: heavy metal content Heavy metals mainly refer to soluble lead, cadmium, chromium, mercury and other substances Some heavy metals are essential trace elements for human body in a certain concentration However, when the amount of heavy metals entering human body exceeds the limit that human body can tolerate, it can cause serious physiological damage and lead to a variety of diseases Lead poisoning is more serious for children, and children have special susceptibility to lead Us code of federal regulations cfr1303 stipulates that lead content greater than 60mg / kg is lead paint, which is forbidden to be used in public places or interior decoration Performance index 1: scrub resistant times The frequency of scrubbing mainly depends on the content and quality of the emulsion The main raw material also determines the main properties of latex paint, such as scrubbing times, weather resistance and color retention Good wall paint products are basically more than 5000 times of scrub resistance, for ultra white products in the market, we should pay more attention to the comparison of scrub resistance times Performance index 2: mould proof and antibacterial performance or ultra white performance, or some waterproof functions 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,
