Wallpaper pk paint, scientific analysis tells you which is more environmentally friendly!

One of the most concerned issues for consumers whenever choosing decorative materials, especially soft materials that are intimately in contact with the body, is environmental security. The most commonly used coatings for wall decoration, in fact, mostly contain toxic substances. Therefore, when more customers in China decorate brand-new houses, they might rather choose wallpapers instead of paints. What are the precise advantages of wallpapers when it comes to environmental protection in accordance with coatings? ? And see the following to know!
First, the composition of wallpaper and paint comparison
1, the main components of the wallpaper
The wallpaper is principally composed of base paper, ink and accessories. There are three primary types of foundation paper: wallpaper base paper (paper bottom and pure paper), nonwoven fabric, and the bottom paper is normally obtained from organic plant fibers such as wood, cotton, and hemp.
Wallpaper accessories could be easily divided into rubber powder, wet glue and foundation film. Rubber powder and wet glue are altered starch processed from potato and corn, which can be degraded in character. The main component of the wet glue is definitely hydroxypropyl distarch phosphate, which is a thickener in yoghurt, and the primary component of the bottom film is an emulsion of styrene and acrylate polymerized in drinking water, namely styrene-acrylic emulsion, which is very green. An intermediate chemical.
2, the main components of the paint
Coatings (also referred to as latex paints) are mainly composed of four parts: base material, pigment, filler and auxiliary agent. The main component of the base materials is a styrene-acrylic emulsion; the inorganic pigment element includes oxides and salts of metals such as carbon black, iron, zinc, chromium, cadmium and titanium, and the organic pigment is split into azo pigments, lakes, copper titanium Classes, fused bands and organic macromolecular pigments; fillers generally include titanium dioxide, kaolin, wollastonite, weighty calcium, light calcium and other powders; and additives mainly include wetting brokers, dispersants, defoamers, Thickener bactericidal fungicide, whitening agent, etc.
Evaluation of wallpaper and color composition Conclusion:
The chemical composition of the paint is very complex, and the raw materials for the wallpaper are mostly from plants. All wallpaper factories have drying processes and plasticizer cooling recovery gadgets in the production process. VOCs are dried and recycled before leaving the factory. When the paint is used, it really is still a liquid, and the volatile matter is normally volatilized at the use site–home, which harms consumers, so the wallpaper is even more environmentally friendly.
Second, the impact on health
1. The paint is seriously dangerous, and the national weighty tax control
In early 2015, the state decided to impose a 4% consumption tax on color. In 10 provinces such as Shanghai and Jiangsu, officially Original Wall covering issued a VOC (carcinogenic volatile matter) sewage charges, it has been proved that the paint has real damage to the atmospheric environment and human health.
2, carcinogen VOC and APEO!
VOC identifies volatile organic substances, which are the source of environmental pollution, harm the mind and nervous system, and are also critical indicators in the formation of smog. The nationwide mandatory standard has a maximum VOC limit of 120 g/L for water-based interior wall coatings, but VOC will volatilize indoors during construction and drying. In 2014, the Shanghai Quality Supervision Bureau carried out quality inspections on the circulating wallpapers in the marketplace. This content of VOCs in the wallpapers was not a lot more than 10 mg/kg. In a nutshell, the VOC articles of latex paints is nearly 12,000 occasions that of wallpapers!
APEO is an abbreviation for alkylphenol ethoxylates and is a trusted non-ionic surfactant. APEO is tough to degrade and has carcinogenic and feminine effects on the body. The two primary indicators for screening the spotted coating items are VOC and APEO. Therefore, weighed against the imported high-end environmentally friendly wallpaper with high basic safety, the coating is harmful to human body on carcinogens. Big.
3. The harm of formaldehyde!
The general coating contains formaldehyde and has a strong irritating taste. Therefore, the paint construction master must wear a mask to avoid inhalation of excessive formaldehyde and poison; while the general wallpaper construction master does not need to put on a mask to carry out the task of posting wallpaper, especially imported high-end wallpaper. With world-class RAL quality qualification, formaldehyde isn’t detected, and the tests standard is 30 occasions stricter compared to the national standard!
