Coating knowledge: main harmful substances and hazards of solvent based wood coatings

Core tip: most of the solvent based wood coatings used for interior decoration use organic matter as solvent Xylene solvent is commonly used in paint industry because of its strong solubility and moderate evaporation rate Type, composition and properties of wood coatings In the process of construction and use, it can cause the indoor air quality to decline, as well as the main volatile organic compounds, benzene, toluene, xylene and other harmful substances that may affect human health 1 Volatile organic compounds (VOC) will pollute the environment and increase the load of indoor organic pollutants Causes severe headache, sore throat and other symptoms Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: most of the solvent based wood coatings for interior decoration use organic matter as solvent Xylene solvent is commonly used in paint industry because of its strong solubility and moderate evaporation rate Type, composition and properties of wood coatings In the process of construction and use, it can cause the indoor air quality to decline, as well as the main volatile organic compounds, benzene, toluene, xylene and other harmful substances that may affect human health 1 Volatile organic compounds (VOC) will pollute the environment and increase the load of indoor organic pollutants Serious causes headache, sore throat and other symptoms, endangering human health 2 Benzene, toluene and xylene are rarely used as solvent in paint manufacturers at present Benzene in wood coatings is mainly brought in by toluene and xylene as impurities The content of benzene is related to the production process of toluene and xylene Considering the type, composition and properties of wood coatings, the main harmful substances are volatile organic compounds, benzene, toluene and xylene, free toluene diisocyanate, soluble lead, cadmium, chromium and mercury In the process of construction and use, the indoor air quality is often reduced, which has a certain impact on human health Volatile organic compounds (VOC) can not only pollute the environment quality, but also increase the load of indoor organic pollutants, which will cause headache, sore throat and harm human health in serious cases Benzene has been recognized as a highly toxic carcinogen by the international cancer research center, which mainly affects the hematopoietic system, nervous system and skin; Free toluene diisocyanate (TDI) is a highly toxic inhalation poison, which has accumulation and latency in human body It is also a mucous membrane irritant, which has a strong irritant effect on eyes and respiratory system, can cause allergic asthma and even asphyxia in severe cases; Soluble lead, cadmium, chromium, mercury and other heavy metal soluble substances have obvious harm to human body Excessive lead can damage nervous system, hematopoietic system and reproductive system, especially affect children's growth and intellectual development Long term inhalation of cadmium dust can damage kidney or lung function Long term exposure of skin to chromium compounds can cause contact dermatitis or eczema Chronic mercury poisoning mainly affects central nervous system 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,
