One of the most concerned issues for consumers whenever choosing decorative components, especially soft materials that are intimately in contact with the body, is environmental safety. The most commonly utilized coatings for wall structure 29058356297 6356109de0 decoration, in fact, mostly contain toxic substances. Therefore, when more consumers in China decorate new houses, they might rather choose wallpapers rather than paints. What are the precise advantages of wallpapers with regards to environmental protection relative to 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 mainly made up of base paper, ink and accessories. There are three primary types of base paper: wallpaper foundation paper (paper bottom and pure paper), nonwoven fabric, and the bottom paper is generally obtained from natural plant fibers such as for example wood, cotton, and hemp.
Wallpaper accessories could be easily split into rubber powder, wet glue and foundation film. Rubber powder and wet glue are modified starch prepared from potato and corn, which can be degraded in nature. The main component of the wet glue is usually hydroxypropyl distarch phosphate, which 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 called latex paints) are mainly made up of four parts: foundation materials, pigment, filler and auxiliary agent. The main component of the base material is a styrene-acrylic emulsion; the inorganic pigment component contains 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 rings and organic macromolecular pigments; fillers primarily consist of titanium dioxide, kaolin, wollastonite, weighty calcium, light calcium and various other powders; and additives mainly include wetting agents, dispersants, defoamers, Thickener bactericidal fungicide, whitening agent, etc.
Assessment of wallpaper and color composition Conclusion:
The chemical composition of the paint is quite complex, and the raw materials for the wallpaper are mainly from plants. All wallpaper factories possess drying procedures and plasticizer cooling recovery products in the production procedure. VOCs are dried and recycled before departing the factory. When the paint is used, it really is still a liquid, and the volatile matter is definitely volatilized at the use site–home, which harms consumers, so the wallpaper is more environmentally friendly.
Second, the impact on health
1. The paint is seriously harmful, and the national large tax control
In early 2015, the state decided to impose a 4% consumption tax on paint. In 10 provinces such as Shanghai and Jiangsu, officially issued a VOC (carcinogenic volatile matter) sewage costs, it has been proved that the color has real damage to the atmospheric environment and individual 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 forming of smog. The national mandatory standard has a maximum VOC limit of 120 g/L for water-based interior wall structure coatings, but VOC will volatilize indoors during building 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 was not more than 10 mg/kg. In short, the VOC articles of latex Simple Wallcovering paints is almost 12,000 instances that of wallpapers!
APEO is an abbreviation for alkylphenol ethoxylates and is a trusted non-ionic surfactant. APEO is difficult to degrade and offers carcinogenic and feminine effects on the human body. The two primary indicators for testing the spotted coating products are VOC and APEO. Therefore, weighed against the imported high-end green wallpaper with high basic safety, the coating is harmful to human body on carcinogens. Big.
3. The harm of formaldehyde!
The overall coating contains formaldehyde and has a strong irritating taste. Consequently, the paint construction get better at must wear a mask to prevent inhalation of extreme formaldehyde and poison; as the general wallpaper structure master doesn’t need to use a mask to handle the work of posting wallpaper, especially imported high-end wallpaper. With world-class RAL quality certification, formaldehyde is not detected, and the screening standard is 30 occasions stricter compared to the national standard!
