Modified starch powder knowledge, worth collecting

With the development of the economy and the improvement of people’s living standards, people are paying more and more attention to the quality and grade of housing decoration. In wall decoration, putty and paint are commonly used instead of wallpaper, ceramic tiles, etc. Most of the interior wall putty and tile putty traditionally used in my country are composed of polyvinyl alcohol (107 glue) or carboxymethyl cellulose mixed with double powder, talc powder, etc. Although these materials meet the requirements for adhesion of building materials and have certain anti-mildew and moisture-proof effects, the overall bonding strength is not high, the putty is easy to crack and fall off, and the water retention, mildew-proof and moisture-proof properties are relatively poor. Mildew is prone to occur in humid environments and may cause problems when used. It has skin and bubble phenomena, and is inconvenient to process, transport, and store. Especially if it contains a large amount of harmful substances such as formaldehyde, it is relatively harmful to the human body and can cause damage to the human nervous system. In severe cases, it can cause poisoning and cancer. It is even more harmful to infants, young children, and the elderly and infirm. There is an urgent need to research and develop a new generation of building putty powder that can replace 107 glue and traditional building putty powder.
