Common knowledge of coating: what are the hazards of epoxy floor coating

Core tip: since the floor paint has been widely used, it has been concerned by many customers Generally, fixed furniture and floor are painted with polyurethane floor paint with fast drying and hard paint film But you may not think that there is a lot of free TDI in the fake polyurethane, which will cause great harm to human body TDI is an abbreviation for toluene diisocyanate, which is mainly used in the manufacture of polyurethane materials, such as polyurethane floor paint and foam plastics commonly used in home decoration Whether it is to produce or use these materials, people will be exposed to volatilization into the air without complete reaction 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: since the floor paint has been widely used, it has been concerned by many customers Generally, fixed furniture and floor are painted with polyurethane floor paint with fast drying and hard paint film But you may not think that there is a large amount of free TDI in the fake polyurethane, which will cause great harm to human body TDI is an abbreviation for toluene diisocyanate, which is mainly used in the manufacture of polyurethane materials, such as polyurethane floor paint and foam plastics commonly used in home decoration Whether producing or using these materials, people will come into contact with TDI which volatilizes into the air without complete reaction That's why when we use some polyurethane floor paint, we can smell strong and irritating smell High content of free TDI is a kind of toxic substance, which has toxic effect on respiratory system After the free TDI is inhaled into the respiratory tract, the light will cause symptoms such as cough, chest distress, asthma, etc., while the heavy will cause pulmonary edema, coma and even death In addition, free TDI can also stimulate the eyes and cause chemical conjunctivitis such as pain, tears and conjunctival congestion After the chemical contacts the skin, it will also produce red papules, contact skin allergies and other symptoms Long term exposure to TDI may lead to cancer TDI is easy to vaporize and volatilize When the polyurethane floor paint is applied, the free TDI in the floor paint will slowly volatilize into the air According to the chemical safety card jointly prepared by the international chemical safety programme (IPCS) and the European Community (CEC), the concentration of TDI in the air is 0.036 mg / m3 Long term exposure to free TDI above this concentration may result in death At present, the TDI content of polyurethane floor paint in China is regulated as follows: the first-class product should be less than 2%, the qualified product should not be controlled without standard, while the foreign country stipulates that the free TDI should not be higher than 0.5% Some of the floor paint production enterprises drill the relatively loose gap of the national regulations, and produce a lot of floor paint containing free TDI, some of which even reach 3% to 7% This kind of polyurethane floor paint, which contains a large amount of free TDI, will not only cause harm to human body, but also produce chemical reaction with latex paint, making the wall uneven yellow, affecting the aesthetic and decorative effect Effective ways to avoid physical injury in order to avoid physical injury to you and your family members, the decoration effect can be successfully achieved, you'd better choose the furniture produced by the furniture factory The paint film of these furniture has been dried and the free TDI has been fully volatilized If you have customized fixed furniture during decoration, the construction of applying emulsion paint and polyurethane floor paint should not be carried out at the same time, and one of them should be fully dried before the other In addition, you should not move in immediately after the decoration, but should open windows and ventilate the new house every day, and then move to the new house after the pungent taste disappears 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,
