Various types of environmental protection paint coating rules

The current coating products are dazzling, clean, full-effect, three-in-one, and five-in-one... A variety of paint and paint products make it impossible for consumers to buy paint. Industry experts and experts recommend that if you want to buy a healthy and environmentally friendly paint and coating product, you should not only look at the price, but mainly look at the "VOC" content.

VOC "hidden" harmful substances

When decorating, one of the issues that people are most concerned about is whether the paint is environmentally friendly and whether it emits toxic gases. But what kind of paint is an environmental health coating? What ingredients, contains a large amount of environmental protection is a healthy coating? According to Zhao Peng, an engineer at the Shaanxi Decoration Materials Quality Inspection Center, VOC values ​​refer to volatile organic compounds such as formaldehyde and benzene in each litre of paint. The content of the compound. Since VOC harm is slow and long-lasting, there is no symptomatic manifestation in the short term, so it is not easy to be noticed and easily overlooked.

Studies have shown that the impact of VOCs on the human body can be divided into three types: First, odors and senses, including sensory stimulation, dry feeling. The second is the pathological state caused by mucosal irritation and other systemic toxicity. It stimulates the mucous membranes of the eye, nasal mucosa, respiratory tract, and skin. VOCs easily pass through blood-brain barriers, resulting in suppression of the central nervous system, causing headaches, fatigue, and fainting. Drowsy and uncomfortable feeling. The third is genetic toxicity and carcinogenicity. Paint coating is one of the main decorative materials for indoor VOC accumulation and indoor pollution. Therefore, everyone must pay attention to the content of VOC when buying decoration paint.

Don't be fooled by "zero VOC"

So what is the VOC content of the coating products in China that is qualified? Zhao Peng said that at present, the national latex paint access standards stipulate that the VOC contained per liter of latex paint cannot exceed 200 grams. Therefore, when consumers purchase paint products, they should first look at the inspection report of their products and see if there is a mark below 200 g in the column indicating VOC content.

This reporter learned that, from the current market conditions, most of the well-known paint brands such as Nippon, Dulux, Garbo Li, Cardan, Crocodile, Lai Wei, etc. are in line with national standards for VOC content standards. However, many brands often introduce to consumers when they sell. Their products not only meet the national standards, but also far exceed the national standards. That is, the VOC content is far less than 200 grams, and even the brand says that its VOC content is close to zero. The promotion successfully seized the health needs of consumers. However, most consumers still doubt whether this so-called "zero VOC" content is credible. Zhao Peng explained that when the numerical content of VOC in the coating is less than 1 gram, the international convention is called "zero VOC." If the merchant claims that the VOC content of his own product is lower than the national standard, it should be corroborated by the inspection report of the corresponding agency to support his claim. Otherwise, this argument is not credible.

Don't blindly worship imports

Zhao Peng introduced that at present, China's implementation of national standards provides that the interior wall latex paint VOC ≤ 200 g / l. Correspondingly, the EU standard requires VOC content ≤ 75 g/l. Obviously, there is a certain gap between domestic "health coatings" and European and American countries. At present, the formulation of new standards in China has been put on the agenda. It is understood that the price of imported paint products on the market is much higher than that of domestic brands. Some consumers gullibly believe that imported brands do not hesitate to spend high prices on imported paints. Zhao Peng reminds consumers that whether it is domestic paint or imported paint, or the so-called imported formula, etc., must see its VOC content test report. Even if they are imported products, some of them are packaged in China or used for OEM production. Consumers must understand their quality and should not be blinded by the “import” label.
