Embossed film is plastic wallpaper, wallpaper at the grass-roots level covered with a layer of PVC plastic film or in the grass-roots spray paste resin paint. Because of its price advantage, is a widely used wallpaper. Today Sheng Fei will lead you to understand its advantages and disadvantages. As just said, the big advantage of this wallpaper is its low price. In addition, it can shape a large three-dimensional shape, waterproof and moisture-proof, durable and easy to maintain. Pollution is also easy to scrub clean. But it contains a large number of chemical raw materials, poor air permeability, easy to mold, long-term in its space is easy to produce discomfort.

Analysis of the causes of embossed film warping: There are many factors that constitute the embossed film warping, which are interrelated to varying degrees. We should synthesize all kinds of information and analyze the essence of the problem in order to draw the correct conclusion. The factors leading to the warping and slitting of the embossed film can be summarized as follows:

1. Human factors: Improper construction of embossed film

(1) sunlight, strong wind, resulting in glue drying speed too fast, uneven shrinkage, local cracking;

The embossing film softens for too long after brushing. Expansion is too long, after drying to form a contraction seam.

The glue concentration is too low, the adhesion is insufficient, and the wallpaper cannot be applied.

glutinous rice glue too much, uneven shrinkage:

When pasting, the scraper is too hard, or the wallpaper is stretched and widened excessively during construction, resulting in excessive stretching. After drying, the wallpaper shrinks to form contraction joints:

When double-layer cutting, the knife edge is repeated, causing the gap to be too obvious.

The seams are not tight when the wallpaper is pasted.

2. Improper embossed film and glue products: including improper product selection and improper product deployment.

Before construction, the wallpaper to be constructed must first be evaluated. Good to do a paste test in advance, choose the right brand of wallpaper glue, do not act on unreliable experience.

Improper selection of products, for example, if there is no reasonable evaluation of whether the selected products are qualified, the wallpaper will be directly pasted with products with unsatisfactory performance. For example, if you paste (thick) wallpaper with wallpaper glue with general performance, it is easy to have problems: non-woven wallpaper, because it is a kind of wallpaper with strong shrinkage, should use wallpaper glue products with strong adhesion, such as special wallpaper glutinous rice glue.

Collocation of glue: improper application, including: the mixing amount of glue and water does not meet the packaging instructions, too much or too little water is added; the mixing time of wallpaper glue is too short, the mixing is uneven, and the adhesion is not fully gelatinized; improper mixing method of workers Lead to ball loss and low viscosity of glutinous rice glue.

Glue stability: refers to the poor stability of the product, prone to abnormal quality. When using wallpaper glue with low viscosity and adhesion to paste wallpaper, it will inevitably affect the quality of wallpaper construction.

Environmental factors: including construction temperature and humidity conditions. Such as the degree of solidity of the base (putty wall), the flatness and water absorption of the wall, the sealing effect of the wall, the bearing capacity of the construction surface, etc. All of them are blind construction when environmental conditions do not allow, which will inevitably lead to problems.
