Film : Film-coated Paper: A Method to Improve the Reuse Rate of Building Formwork
1. The surface of the formwork paint film is bright and plump, with good smoothness. The coated paper can naturally form enamel to make up for the surface defects of the building formwork.
2. Template paint film thermal decomposition temperature is about 350 C. It has good heat resistance and alkalinity (saturated calcium hydroxide 80 C immersed for 48h physical and chemical properties do not decline), and is very suitable for the use of building formwork environment.
3. Most of the building formwork in the construction project is stacked in the open air. It is a difficult problem to protect the paper-covered wooden building formwork from corrosion. Formwork paint has excellent anti-corrosion and anti-rust properties. Because of the isolation effect of paint film, building formwork can avoid the erosion of concrete sand and stone and cement hydrate. It can effectively improve the reuse rate of building formwork and prolong the service life of building formwork.
