Nov 13, 2022
When users go to the shop to buy wallpaper and wallcoverings for decoration, they will find that the shopkeeper will ask users to buy a matching package of [glutinous rice glue+wall base film], and often users will not understand why the base film is used for wallpaper pasting?
First of all, let's define the base film: the main component of the wall base film is acrylic acid+additives. After opening the cover, we can see that it is an milky white liquid, but the smell is obviously much heavier than that of glutinous rice glue (a heavy smell does not mean that it contains formaldehyde, in fact, formaldehyde is colorless and tasteless). The role of the base film is to strengthen the wall base course, form a protective layer on the wall surface, isolate moisture and alkaline substances from the wall, play the role of alkali resistance, moisture resistance and mold resistance, make the wallpaper not easy to change color, mildew, edge warping, and extend the service life of the wallpaper. Therefore, the role of the basement membrane needs to be affirmed.
If it is a latex painted wall or a wall with a dry and solid wall surface in a dry home climate, and you do not plan to replace the wallpaper in the short term, you can only use glutinous rice glue instead of the base film.
Secondly, let's define glutinous rice glue: glutinous rice glue is an adhesive for wallpaper and wall cloth. It is made from edible starch with sorbic acid (preservative), ethanol, white vinegar and other additives.
When using, add water directly to mix, and the product opens in a milky white viscous shape without any peculiar smell, which is very consistent with your intuitive requirements for environment-friendly materials.
Although the reputation of the basement membrane is not as good as that of glutinous rice glue, its practical effect cannot be ignored.
Since they are all home decoration materials, we are most concerned about their environmental protection.
The so-called environmental protection, for consumers, means that the indoor air quality of the new home is qualified and they can settle in.
