Problems solved by technology

[0002] Since the last century, the decoration of wallpaper has been loved by more and more people. Up to now, indoor wallpaper decoration in our country has been very common. With the popularization of wallpaper and wallpaper adhesive closely related to wallpaper, it has also emerged at the historic moment. It is widely used in the market. Carboxymethyl cellulose and polyvinyl formal are more widely used, but carboxymethyl cellulose has poor water retention and is not easy to bond firmly. Polyvinyl formal contains free formaldehyde, which is not conducive to human health. The enhancement of people's health awareness has higher requirements for the quality of adhesives
Starch is a safe and environmentally friendly renewable resource with good cohesiveness and film-forming properties, but it still cannot meet the performance requirements of factory production
