How To Judge The Stickiness Of Wallpaper Glue?

Wallpaper curling is a common problem with home wallpaper. Recently, some friends continue to report that the wallpaper curling in the bedroom, the living room, and the bathroom wallpaper. What is the reason for the wallpaper curling?

There are three main reasons for the warped edge of the wallpaper: the wall is not properly treated, the wallpaper is not selected according to the wallpaper material, and the adhesive viscosity is not good. However, the adhesiveness is not good, which has a great influence on the construction effect.

However, as a consumer, after working hard to choose a satisfactory wallpaper, they often ignore the purchase of wallpaper glue. In fact, choosing glue with good viscosity and good quality can effectively avoid some warping and bubbling after the wallpaper construction. problem.

From a professional perspective, consumers can distinguish from two aspects:

(1) Adhesion. Adhesive force usually refers to the force that attracts and connects the adhesive and the surface of the object to be bonded through the interface. Wallpaper glue with good adhesion is generally easy to stick the wallpaper, but also difficult to tear off. When choosing wallpaper glue, we can ask the staff to try the stickiness of the glue, or try the stickiness directly by hand.

(2) Viscosity. Viscosity is a concept used to measure the internal flow resistance of viscous liquids. In daily life, viscosity is like "viscosity." For example, we often say that water is "thin", which means low viscosity. general speaking. We can compare the viscosity of the glue by simple observation.

●Comparison of liquidity. The fluid with low viscosity has better fluidity. Therefore, when choosing bottled glue, we can directly invert the two bottles of glue to compare which bottle of glue flows fast, and which flows faster is more "dilute". Looking at the picture below, after the two bottles of glue are inverted, the glue on the left recovers faster than the glue on the right, and the glue on the right has better viscosity.

●View the viscosity value. Nowadays, many wallpaper glues on the market will be marked with a viscosity value. Consumers can directly read the instructions on the back of the package when purchasing.

Generally speaking, the viscosity of the wallpaper should reach 20000 mpa·s (viscosity unit: millipascal second), and the glutinous rice glue with 50000 mpa·s in the picture should reach the viscosity of the thick and heavy wall covering.　　

All in all, after you have bought wallpaper, don't try to save trouble, just put up wallpaper glue. The quality of the wallpaper glue greatly affects the subsequent wallpaper pasting effect. Of course, the wallpaper that has been chosen by thousands of choices will last forever when it is on the wall, and I am most worried about various problems over time. Home decoration is afraid of many follow-up problems, and can be avoided as soon as possible.
