As a wall decoration material, the wall covering is available in a variety of color designs.

The brighter the color and the better the color fastness of the wall covering, the more color-fixing materials are used; The formaldehyde content in such materials is very high, which is not good for environmental protection and the human body.

Hello, the advantages of wall covering:1Moisture and mildew resistant.

2.The construction is simple and fast. 3. Strong anti-fouling.

Wallcovering can reflect a variety of different colors, different depths, and different brightness designs on one wall.

Latex paint walls can only have one color.

In terms of three-dimensional effect, the wall cloth is more plastic, taking a wall as an example, a variety of three-dimensional effects with different patterns and depths are designed, while latex paint can only have a single plane effect.

In terms of design style, wall covering can be designed with various textures and patterns, while latex paint can only be one color.

Precautions for Renovation Toxicity:Wall cloth is generally a kind of fabric decorated on the wall, and the base cloth is mainly cotton.

The formaldehyde of wallpaper and wallcovering is mainly produced in the base film and glue used in the construction, and it is necessary to pay attention to see whether the formaldehyde exceeds the standard of the glue and base film of the construction.

In general, the wallcovering itself is environmentally friendly and non-toxic. However, in the construction process of wallpaper, the glue contains a high amount of formaldehyde and other harmful substances. In home improvement materials, it is not only possible to determine whether a material contains toxic and harmful substances and whether it is environmentally friendly.

It also depends on what auxiliary materials are needed in the construction process. As mentioned above, the wall cloth itself does not contain formaldehyde, which is a green and environmentally friendly material, but the wall cloth is pasted on the wall, which is to use glue, as long as it is glue, there will be formaldehyde and so on.

At the end of the day, what really contains formaldehyde is the adhesive used to stick the wallpaper. This adhesive will contain formaldehyde and xylene. These are volatile substances that are harmful to the human body and have a relatively long release period.

At present, the recommended adhesive on the market is an environmentally friendly glutinous rice adhesive. This material is not free of formaldehyde and xylene, but the content is relatively low and the release time is relatively short. Generally speaking, the wallpaper itself does not contain formaldehyde.

However, in the construction process of wallpaper, the glue contains a high amount of formaldehyde and other harmful substances. In home improvement materials, it is not only possible to determine whether a material contains toxic and harmful substances and whether it is environmentally friendly. It also depends on what auxiliary materials are needed in the construction process.

As mentioned above, the wallpaper itself does not contain formaldehyde, which is a green and environmentally friendly material, but the wallpaper is pasted on the wall, it is necessary to use glue, as long as it is glue, there will be formaldehyde, etc., and the wallpaper cannot be closely attached to the wall with tap water and keep it from falling.

The general wall covering is not harmful, and the harmful ones on the market are generally low-cost wall coverings

Hazards of low-cost wallcovering:

1. Raw material hazards of low-cost wall coverings:

The reason why the low-cost wall covering is as low as ten or twenty pieces is mostly because the wall covering manufacturers reduce the input from raw materials. The raw materials required for the main production are important factors in the quality of wall coverings. In order to reduce the quality of non-woven gauze put into use by low-cost wallcovering manufacturers, this has seriously led to a sharp decline in the quality of engineering wallcoverings.

2. Quality control hazards of low-cost wall coverings:

The generation of low-cost wallcovering lies in the control of costs, and in terms of product quality control, there will be omission of inspection and lax control, so as to reduce the rejection rate of products and increase the output of products. For customer complaints and repairs of inferior quality products on the market, they also avoid talking about it, which has caused the market for low-cost wall coverings to gradually shrink.

3. Construction hazards of low-cost wall coverings:

The defects of the low-cost wall cloth itself are undoubtedly leaked in the construction process of the wall cloth, and the wall is posted: uneven patterns, warping, color difference, smell, overall effect, etc., there are quality problems of the wall cloth, and in the process of acceptance, it will face greater problems.

Cons: First, it is expensive. Compared with latex paint and ordinary wallpaper, the ** of wall cloth is more expensive.

The average per square meter is hundreds of yuan, and a bedroom is paved with thousands of yuan. A bucket of latex paint for a few hundred yuan can paint the entire bedroom, so many people feel that the fatal disadvantage of wall cloth is that it is not cost-effective.

Second, the requirements for construction technology are cautious and sensitive. The fatal disadvantage of wall covering is that the requirements for construction technology are relatively high. In the process of construction, it is necessary to clean up the wall in advance, especially in summer, even if the gypsum powder is used to fill the gaps, but there are still bubbles on the wall, which is very likely to be the wall is damp, and there will be small bubbles in the wall cloth in the later stage, which affects the aesthetics, and is also easy to cause mold on the wall.

Third, the loss is large. The wall covering needs to be cut according to the actual needs, if the cutting is too wasteful, then these extra fabrics have no other purpose, but it is very expensive.

Hazards: First, low-grade chemical fiber fabrics. As a kind of textile in the wallcovering itself, if you use a wallcovering made of low-grade chemical fiber material, you can feel it on the touch

Hard, smooth, plastic. This low-grade material wall covering product has weak air permeability and insufficient fastness, and will be deformed and moldy inside with the passage of time.

Second, the dye exceeds the standard. As a wall decoration material, wallcovering has a variety of color designs. In order to make the low-grade wall cloth have bright colors and color fastness, some bad manufacturers will use a large number of color-fixing materials, which have a high composition of formaldehyde and auspicious branches, which is not conducive to environmental protection, and no matter how much color-fixing materials are used, they will definitely fade.

The precautions for purchasing wallcovering are as follows.

First, when choosing a wall covering, it is necessary to check whether the color on the surface of the wall covering is evenly distributed, and whether there are problems such as color difference, bubbles, and wrinkles. All surfaces are evenly distributed, and the pattern will be clearer. When checking the workmanship, pay attention to both sides to see if there will be a problem of pattern penetration.

Second, by touching the feel of the wallcloth to perceive the quality of the wallcloth, generally speaking, the uniformity of the wallcloth is more important, so when touching the wallcovering, you should feel whether the thickness of the wallcloth is uniform, but the thickness can not be used to judge the quality of the wallcloth, and the same quality of the wallcloth will also have a difference in thickness.

Third, when purchasing wall coverings, the environmental protection of wall coverings is also more important. You can judge whether the strength contains chemical components by smelling the smell of the wallcovering, and the wallcovering with poor quality workmanship will generally be relatively cheap and contain a large number of harmful substances, so the smell will be pungent compared to the early liquid.
