Dear friends who need to put up wall coverings and wall coverings at home recently, when you choose wall coverings, you are always more interested in hot glue wall coverings, but you don’t know much about hot glue wall coverings. What is it? What about hot glue? In this issue, the editor will take you through the differences between hot glue wall coverings.
First of all, hot glue is also called hot melt glue . The basic resin of hot melt glue is ethylene and vinyl acetate copolymerized under high temperature and pressure. It is a plastic adhesive that is solid at room temperature. .
It will produce a physical change under high temperature and air pressure, thus forming a melted colloid. It has very strong viscosity and stability, so it is widely used for bonding non-woven fabrics, carpet seams, etc. . It is not only environmentally friendly but also has extremely stable viscosity. Because its glue requires high temperature and pressure to produce viscosity, it is called hot glue.
Advantages of hot glue wall covering
Using hot glue wall covering to stick to the wall has a more beautiful effect, is more environmentally friendly, has good breathability, strong adhesion, is not prone to mold, and has stronger stability. It is very suitable for use in humid places and is not used at home. I am worried that the hot glue wall covering will fall off and other problems.
Some people may say that hot glue wall covering glue is used, but we don’t know what it is like and we can’t choose. How can we be sure that it is environmentally friendly? Therefore, the environmental protection of hot glue wall coverings has always been controversial in this regard, but most of the hot glue wall coverings currently on the market have a layer of hot melt mesh on the back.
Hot-melt omentum
Hot-melt omentum is classified according to its ingredients: PA, PES, EVA, TPU, etc. Hot-melt omentum with different components can be derived into hundreds of different types according to its different melting point, elasticity, use temperature, etc. Model hot melt mesh.
Most hot glue wall coverings currently on the market use EVA (EVA is a plastic material, its chemical name is ethylene-vinyl acetate copolymer. Products made from this type of material have good softness, shock resistance, It has strong anti-slip and pressure resistance. The slippers, cotton shoes and mobile phone protective cases we wear in our daily life are all made of this material. ) is used to make hot-melt mesh. The melting point of its products is around 70℃. .
Advantages of hot-melt mesh
Hot-melt mesh is more environmentally friendly than traditional adhesives and will not produce an irritating smell when pasted; the thickness of the hot-melt mesh is also relatively uniform, and it will stick more closely when pasting wall coverings Smooth and more beautiful effect. It will melt into a colloid at high temperatures and has strong viscosity. It will condense into a solid at low temperatures and has strong stability. Unlike traditional glue, which will cause mold and other problems after being pasted.
Disadvantages of hot glue wall coverings
First of all, the price of hot glue wall coverings is much more expensive than that of cold glue wall coverings. Secondly, the construction is more complicated, especially in the corners, which is more difficult to handle! In a relatively high-temperature environment, problems such as melting, bulging, and falling off may easily occur. Follow me and I will take you to learn more about home decoration.
