One of the most concerned problems for consumers when choosing decorative materials, especially soft materials that are intimately in touch with your body, is environmental protection. The most commonly used coatings for wall structure decoration, actually, mostly contain toxins. Therefore, when more customers in China decorate new houses, they might rather choose wallpapers rather than paints. What are the precise advantages of wallpapers in conditions of environmental protection relative to coatings? ? And 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 primary types of bottom paper: wallpaper base paper (paper bottom and pure paper), nonwoven fabric, and underneath paper is normally 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 base film. Rubber powder and wet glue are modified starch processed from potato and corn, which may be degraded in character. The main element of the wet glue can be 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 quite environmentally friendly. An intermediate chemical.
2, the main parts of the paint
Coatings (also called latex paints) are mainly made up of four parts: bottom materials, pigment, filler and auxiliary agent. The primary component of the base material is a styrene-acrylic emulsion; the inorganic pigment element contains oxides and salts of metals such as 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 consist of titanium dioxide, kaolin, wollastonite, heavy calcium, light calcium and additional powders; and additives generally 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 recycleables for the wallpaper are mainly from plants. All wallpaper factories have drying processes and plasticizer cooling recovery devices in the production procedure. VOCs are dried and recycled before departing the factory. When the paint 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 more environmentally friendly.
Second, the effect on health
1. The color is seriously harmful, 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 for example Shanghai and Jiangsu, officially released a VOC (carcinogenic volatile matter) sewage fees, it’s been proved that the color has real harm to the atmospheric environment and individual health.
2, carcinogen VOC and APEO!
VOC refers to volatile organic substances, which are the way to obtain environmental pollution, harm the mind and nervous program, and are also critical Pure paper Wallcoverings indicators in the formation of smog. The nationwide mandatory standard has a maximum VOC limit of 120 g/L for water-based interior wall structure coatings, but VOC will volatilize indoors during structure and drying. In 2014, the Shanghai Quality Supervision Bureau executed quality inspections on the circulating wallpapers out there. This content of VOCs in the wallpapers was not a lot more than 10 mg/kg. In a nutshell, the VOC content material of latex paints is nearly 12,000 times that of wallpapers!
APEO is an abbreviation for alkylphenol ethoxylates and is a trusted nonionic surfactant. APEO is hard to degrade and has carcinogenic and feminine effects on our body. The two main indicators for examining 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. Consequently, the paint construction get better at must use a mask to prevent inhalation of excessive formaldehyde and poison; as the general wallpaper construction master doesn’t need to wear a mask to handle the work of posting wallpaper, especially imported high-end wallpaper. With world-class RAL quality qualification, formaldehyde isn’t detected, and the tests standard is 30 times stricter than the national standard!
