One of the most concerned issues for consumers when choosing decorative components, especially soft materials that are intimately in touch with your body, is environmental protection. The most commonly used coatings for wall structure decoration, in fact, mostly contain toxic substances. Therefore, when more customers in China decorate brand-new houses, they would rather choose wallpapers instead of paints. What are the specific advantages of wallpapers when it comes to environmental protection relative to coatings? ? And start to see the following to know!
First, the composition of wallpaper and paint comparison
1, the main elements of the wallpaper
The wallpaper is mainly composed of base paper, ink and accessories. There are three main types of base paper: wallpaper base paper (paper bottom and pure paper), non-woven fabric, and the bottom paper is generally obtained from organic plant fibers such as for example wood, cotton, and hemp.
Wallpaper accessories can be easily split into rubber powder, wet glue and bottom film. Rubber powder and wet glue are altered starch prepared from potato and corn, which can be degraded in character. The main element of the wet glue is certainly hydroxypropyl distarch phosphate, which really is a thickener in yoghurt, and the main component of the base film can be an emulsion of styrene and acrylate polymerized in drinking water, namely styrene-acrylic emulsion, which is very green. An intermediate chemical.
2, the main elements of the paint
Coatings (also known as latex paints) are mainly made up of four parts: foundation materials, pigment, filler and auxiliary agent. The primary component of the bottom materials is a styrene-acrylic emulsion; the inorganic pigment component includes oxides and salts of metals such as carbon black, iron, zinc, chromium, cadmium and titanium, and the organic pigment is divided into azo pigments, lakes, copper titanium Classes, fused rings and organic macromolecular pigments; fillers primarily consist of titanium dioxide, kaolin, wollastonite, large calcium, light calcium and additional powders; and additives mainly include wetting agents, dispersants, defoamers, Thickener bactericidal fungicide, whitening agent, etc.
Comparison of wallpaper and color composition Conclusion:
The chemical composition of the paint is quite complex, and the recycleables for the wallpaper are mainly from plants. All wallpaper factories possess drying procedures and plasticizer cooling recovery gadgets in the production procedure. VOCs are dried and recycled before leaving the factory. When the color is used, it is still a liquid, and the volatile matter is usually volatilized at the utilization site–home, which harms customers, so the wallpaper is even more environmentally friendly.
Second, the impact on health
1. The color is seriously harmful, and the national weighty tax control
In early 2015, the state made a decision to impose a 4% consumption tax on paint. In 10 provinces such as for example Shanghai and Jiangsu, officially released a VOC (carcinogenic volatile matter) sewage fees, it’s been proved that the paint has real harm to the atmospheric environment and individual health.
2, carcinogen VOC and APEO!
VOC refers to volatile organic substances, which are the source of environmental pollution, harm the mind and nervous program, and are also critical indicators in the formation of smog. The nationwide mandatory standard includes a maximum VOC limit of 120 g/L for water-based interior wall coatings, but VOC will volatilize indoors during structure and drying. In 2014, the Shanghai Quality Guidance Bureau conducted quality inspections on the circulating wallpapers in the marketplace. The content of VOCs in the wallpapers had not been a lot more than 10 mg/kg. In a nutshell, the VOC articles of latex paints is nearly 12,000 instances that of wallpapers!
APEO can be an abbreviation for alkylphenol ethoxylates and is a trusted nonionic surfactant. APEO is challenging to degrade and offers carcinogenic and feminine effects on our body. The two primary indicators for tests the spotted coating Pure paper Wallcovering products are VOC and APEO. Therefore, weighed against the imported high-end environmentally friendly wallpaper with high safety, the coating is bad for body on carcinogens. Big.
3. The harm of formaldehyde!
The overall coating contains formaldehyde and includes a strong irritating taste. As a result, the paint construction master must use a mask to avoid inhalation of extreme formaldehyde and poison; as the general wallpaper construction master does not need to put on a mask to carry out the work of posting wallpaper, specifically imported high-end wallpaper. With world-class RAL quality certification, formaldehyde isn’t detected, and the testing standard is 30 situations stricter compared to the national standard!
