1. Adding protective film, also known as film covered formwork, has good physical characteristics, good adhesion (bonding strength with steel up to 9Mpa), wear resistance and alkali resistance after adding a layer of protective film to the building formwork. It can be reused for many times and can effectively protect the building formwork.
2. The formwork paint has excellent anti-corrosion and anti rust performance. Due to the isolation effect of the paint film, the building formwork can be free from the abrasion of concrete, sand and stone and the corrosion of cement hydrate, which can effectively improve the reuse rate of the building formwork and prolong the service life of the building formwork.
3. The surface of the formwork paint film is bright and full, with good finish, and can naturally form enamel to make up for the surface defects of the building formwork.
4. The thermal decomposition temperature of the paint film of the formwork paint is about 350 ℃, with good heat resistance and alkalinity (saturated calcium hydroxide is soaked at 80 ℃ for 48h, and the physical and chemical properties do not decrease), which is very suitable for the use environment of building formwork.
The advantages of wood plastic building formwork have been widely known. Its high cost performance is an important reason for many builders to choose it.
In terms of service life, the wood plastic building formwork is used dozens of times more than the old bamboo and wood formwork. Although its price is about three times that of the old bamboo and wood formwork, its amortization cost is still less than half of the old bamboo and wood formwork. What's more, the wood plastic building formwork can be recycled even after it is crushed. Its recycling price is about 30% of the sales price. In this case, Firstly, the problem of construction waste treatment was solved. More importantly, the amortization cost of formwork in construction was further reduced. This wood plastic formwork is an important product for each builder to save costs.
