Coating knowledge: the choice of coating for home users

Core tip: before choosing wall paint, we should first learn the environmental protection knowledge of wall paint, and then choose products according to these key indicators Environmental protection index 1: VOC (volatile organic compounds) content At present, the country implements the compulsory implementation standard, 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 VOC compounds have been proved to be carcinogens or suspicious carcinogens Environmental protection index 2 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: before choosing wall paint, we should first learn the environmental protection knowledge of wall paint, and then choose products according to these key indicators Environmental protection index 1: VOC (volatile organic compounds) content At present, the country implements the compulsory implementation standard, 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 VOC compounds have been proved to be carcinogens or suspicious 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 After understanding the environmental indicators and product performance of the above products, we can start from the following steps when selecting products Step 1: choose regular big brand products or regular channels for purchase Paint and coating products are not only related to the beauty and comfort of the living environment, but also related to the health of the family Step 2: check the test report of the products recommended by the shopping guide Corresponding to the above mentioned several environmental protection indicators, at the same time, pay attention to whether the performance indicators are described on the product packaging Step 3: choose products reasonably According to the member structure and consumption ability of one's own family to determine the products to be purchased, what is specially proposed here is that the alkali resistant primer of the wall paint should not be saved If the family condition is good, some products with special performance can be considered in the selection of the wall paint, such as children's paint, super scrub resistant top coat, etc step 4: carry out anti-counterfeiting query of the products Understand the anti-counterfeiting query methods of purchased products and conduct relevant anti-counterfeiting queries on products Step 5: understand the after-sales service carefully Step 6: check the final effect In case of any comments, feedback or communication shall be made to the distribution store in time to protect their maximum rights and interests In addition: according to the different functions of the room, choose the latex paint with corresponding characteristics When choosing the latex paint with good cost performance, choose the latex paint with corresponding characteristics according to the different functions of the room For example, the best choice for toilets and basements is the ones with good mildew resistance, the ones for kitchens and bathrooms are the ones with good stain resistance and scrub resistance, and the ones with certain elasticity are the ones for covering cracks and protecting wall decoration Assuming that your living environment is humid, you can choose the wall paint with better anti mildew function to make the wall body more durable, such as 5 in 1 emulsion paint of various brands and full effect integration of gold decoration If you have children who like to paint on the wall, easy to clean wall paint is the best choice For example, the third generation of super washable or children's emulsion paint of various brands is a good choice Due to the close relationship and even mutual restriction between various properties of coating products, the single performance may not be prominent for the multi-functional products popular in the market, but the comprehensive performance is generally good Decorative paint can be divided into wall paint (including indoor and outdoor) and wood decoration paint according to different components In general, the interior wall paint shall be used for the wall body and ceiling;
