Problems solved by technology

[0003] At present, there are many kinds of wallpaper wet glue on the market, and the quality is uneven

For example, some are directly boiled with dextrin, and some are made with ordinary wheat starch gelatinization, and the viscosity index and viscosity strength are far apart.

And because the main raw material of wallpaper wet glue is starchy organic polymer, it is easy to mold and deteriorate.

At present, some wallpaper wet glues on the market generally use organic anti-mildew systems to prevent mildew. However, the organic anti-mold system will be gradually consumed in the process of resisting microbial erosion such as bacteria and molds, so that the wallpaper wet glue will gradually lose.
