the latex paint on the market can be described as a mixture of fish and eyes. Due to the recognition of environmental protection materials, many businesses call it buy under the name of environmental protection latex paint. So, how to distinguish environmental friendly interior wall emulsion paint? Now let's introduce how to choose environmentally friendly interior wall emulsion paint

how to choose and buy environment-friendly interior wall emulsion paint

I. identify the quality of environment-friendly emulsion paint

1. Open the cover of the paint pass and ask about the smell of the paint. Truly environmentally friendly latex paint is water-based, non-toxic and tasteless, so if you smell pungent odor or industrial essence, it may be inferior latex paint, so don't choose. After the emulsion paint is placed for a period of time, the surface of the genuine emulsion paint will form a thick elastic oxide film, which is not easy to crack. The inferior latex paint products will only form a thin film, which is fragile and has a pungent smell

2. Mix the emulsion paint with a wooden stick, and then pick it up with a wooden stick. When the high-quality emulsion paint flows down, it will form a fan shape

3. The quality of latex paint can be measured by touching with your fingers. The authentic latex paint feels smooth and delicate

4. A little latex paint can be brushed onto the cement wall, and the coating can be wiped with a wet rag after it is dry. The latex paint with good quality has strong scrubbing resistance, and it will not have a significant impact on the appearance of the coating after one or two hundred times of wiping, while the fading phenomenon of powder falling and bottom exposure occurs when the low-grade water-soluble coating is wiped only a dozen times. When the emulsion paint is painted on the wall, the color of the authentic product is as bright as new, bringing a good visual effect. When choosing latex paint, be sure to look at the ingredients. The composition of high-quality emulsion paint should be copolymer resin or pure acrylic resin. In addition, pay attention to the shelf life of products to avoid buying expired products

second, the purchase of environmentally friendly latex paint is more

the purchase of latex paint, consumers may be most concerned about environmental protection and price

the most important environmental protection index of latex paint is the content of volatile organic compounds (VOC). The national standard stipulates that the VOC content in each liter of emulsion paint shall not exceed 200 grams. In order to make it convenient for consumers to buy latex paint, recently, the China Consumer Association, together with the consumer associations of Beijing, Shanghai, Guangdong and Sichuan provinces and cities, conducted a comparative test of 83 kinds of interior wall latex paint products

III. identify the brand paint coating

according to the published results, the environmental protection performance of latex paint basically meets the standard, and the contents of volatile organic compounds (VOC) and soluble heavy metals in all samples meet the national standards; Only one sample of formaldehyde content exceeds the upper limit of the national standard. The 83 samples used in the experiment were purchased from 19 building materials markets or supermarkets in Beijing, Shanghai, Chengdu and Guangzhou, covering major international and domestic well-known brands and local brands, as well as products of the same brand at different prices. Therefore, consumers who pay attention to environmental protection can give priority to the purchase of brand latex paint

IV. check whether it is environmentally friendly

the detection of harmful substances in environmental protection of latex paint is mainly the detection of volatile organic compounds (VOC), free formaldehyde, and four kinds of heavy metals such as soluble lead, fusible cadmium, soluble chromium, and soluble mercury. According to GB 18582-2001“ Limit of harmful substances in interior wall paint of interior decoration materials ” The national standard is: voc≤ 200g/L; Free formaldehyde ≤ 0.1g/kg; Soluble lead ≤ 90mg/kg; Soluble cadmium ≤ 75mg/kg; Soluble chromium ≤ 60mg/kg; Soluble mercury ≤ 60mg/kg。 Many brands can meet the national standards, but some well-known brands in the market will have a particularly low content of harmful substances in their products, so there will be few harmful ingredients to the human body

the above brief introduction about how to choose and buy environmental friendly interior wall emulsion paint is here. I hope it will be helpful to you. Please look forward to more information
