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

One of the most concerned problems for consumers when choosing decorative materials, especially soft components that are intimately in touch with your body, is environmental protection. The most commonly used coatings for wall decoration, actually, mostly contain toxic substances. Therefore, when more consumers in China decorate brand-new houses, they would rather choose wallpapers instead of paints. What are the precise advantages of wallpapers in conditions of environmental protection in accordance with 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 principally composed of base paper, ink and accessories. There are three main types of foundation paper: wallpaper base paper (paper base and pure paper), non-woven fabric, and underneath paper is normally obtained from organic plant fibers such as for example wood, cotton, and hemp.
Wallpaper accessories can be easily divided into rubber powder, wet glue and bottom film. Rubber powder and wet glue are altered starch prepared from potato and corn, which may be degraded in character. The main element of the wet glue is normally hydroxypropyl distarch phosphate, which is a thickener in yoghurt, and the primary component of the bottom film can be an emulsion of styrene and acrylate polymerized in water, namely styrene-acrylic emulsion, which is quite environmentally friendly. An intermediate chemical.
2, the main components of the paint
Coatings (also referred to as latex paints) are mainly composed of four parts: bottom material, pigment, filler and auxiliary agent. The primary component of the base materials is a styrene-acrylic emulsion; the inorganic pigment element contains oxides and salts of metals such as for example carbon dark, iron, zinc, chromium, cadmium and titanium, and the organic pigment is divided into azo pigments, lakes, copper titanium Classes, fused bands and organic macromolecular pigments; fillers mainly include titanium PVC Wall covering dioxide, kaolin, wollastonite, heavy calcium, light calcium and other powders; and additives primarily include wetting brokers, dispersants, defoamers, Thickener bactericidal fungicide, whitening agent, etc.
Comparison of wallpaper and paint composition Conclusion:
The chemical composition of the paint is very complex, and the recycleables for the wallpaper are mainly 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 is still a liquid, and the volatile matter is normally volatilized at the use site–home, which harms consumers, therefore the wallpaper is more environmentally friendly.
Second, the effect on health
1. The color is seriously dangerous, and the national weighty tax control
In early 2015, the state made a decision to impose a 4% consumption tax on color. In 10 provinces such as for example Shanghai and Jiangsu, officially issued a VOC (carcinogenic volatile matter) sewage charges, it’s been proved that the paint has real harm to the atmospheric environment and human being health.
2, carcinogen VOC and APEO!
VOC refers to volatile organic substances, which are the way to obtain environmental pollution, damage the mind and nervous program, and are also important factors in the formation of smog. The nationwide mandatory standard has a optimum VOC limit of 120 g/L for water-based interior wall structure 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 on the market. The content of VOCs in the wallpapers was not more than 10 mg/kg. In a nutshell, the VOC content of latex paints is nearly 12,000 times that of wallpapers!
APEO can be an abbreviation for alkylphenol ethoxylates and is a widely used non-ionic surfactant. APEO is hard to degrade and has carcinogenic and female effects on the body. The two main indicators for tests the spotted coating items are VOC and APEO. Therefore, compared with the imported high-end environmentally friendly wallpaper with high security, the coating is bad for body on carcinogens. Big.
3. The damage of formaldehyde!
The general coating contains formaldehyde and has a strong irritating taste. Therefore, the paint construction master must put on a mask to avoid inhalation of extreme formaldehyde and poison; while the general wallpaper construction master does not need to wear a mask to carry out the task of posting wallpaper, specifically imported high-end wallpaper. With world-class RAL quality certification, formaldehyde is not detected, and the examining standard is 30 situations stricter than the national standard!
