As people's living standards are getting higher and higher, and their living tastes are getting higher and higher, wall coverings have become the choice of more people in home decoration. Although wall coverings and latex paint have their advantages and disadvantages, the rich colours and more nice texture of wall coverings have become why people tend to choose them.
However, with the awakening of people's awareness of environmental protection and more and more attention to their health problems, people have gradually noticed the hidden danger of formaldehyde release in wall coverings. Since the glue is needed to paste the wall covering on the wall, people have begun to pay attention to the problem of what glue to use for the wall covering.
So, what glue is used for the wall covering? Is there any harm in it? Below we will briefly introduce you.
At present, there are mainly two kinds of processes for the pasting of wall coverings on the wall, one is the widely used cold glue process, and the other is the relatively small hot glue process. The cold glue process uses traditional glutinous rice glue, and the hot glue process uses hot melt adhesive film to paste and uses a steam iron to iron the wall. In fact, from the perspective of environmental protection, these two kinds of glue are environmentally friendly.
Let's talk about glutinous rice glue first. Glutinous rice glue is actually a water-based adhesive. It uses water to replace traditional organic solvents as solvents, so there is no solvent volatilization. Let's talk about hot melt adhesive film. Hot melt adhesive film is an adhesive product with a solid content of 100%. The hot melt adhesive film used on wall coverings is generally EVA hot melt adhesive film. Its main component is EVA. Acetic acid-vinyl acetate polymer, together with some tackifying resins and waxes, does not contain any solvent, and there is no problem of solvent volatilization, so in essence, it is also environmentally friendly.
For consumers, in fact, as long as they choose products produced by regular manufacturers, they don't have to worry too much about the environmental protection issues of the products. In principle, these two adhesives do not have the volatilization of harmful substances and can be used with confidence.
It is worth noting that it is not that the glue of the wall covering does not contain formaldehyde to mean that the wall covering is formaldehyde-free. Contrary to the traditional concept, the formaldehyde release of the wall covering does not actually come from the adhesive but from its base fabric. There are many kinds of colour patterns in the production of wall coverings. The function of formaldehyde is to fix the colour, so in the production of fabrics, formaldehyde is needed. If the process is not well controlled, formaldehyde will remain in the base fabric. So, again, when we choose a wall covering brand, we try to choose products produced by some regular manufacturers, so that the guarantee will be higher.
