PVC Formwork: A New Type of Energy-Saving and Environmentally Friendly Building Material

PVC building formwork, also known as wood-plastic formwork, plastic formwork or plastic-steel formwork, is a new type of building material made of PVC resin and a variety of additives through a special process. The following is a detailed analysis of PVC building form:

1. Environmental Protection and Energy Saving

Green and environmental protection: In the production process, PVC building shuttering mainly uses discarded corner wood powder, wood chips and slag wood and other raw materials, mixed with PVC resin, calcium carbonate, stabilizer and other processing aids, and extruded at high temperature. This production method not only reduces resource waste, but also reduces environmental pollution.

Energy saving: Compared with traditional steel formwork and wooden formwork, PVC building formwork has lower energy consumption during use. Its amortization cost is low, and it can be used repeatedly, which is in line with the current development trend of energy conservation and environmental protection.

2. Excellent performance

Physical properties: PVC building formwork is light in weight, more than 30%-40% lighter than traditional wooden square formwork, which is convenient for handling and construction. At the same time, it has good impact resistance and wear resistance, and can be used in harsh environment.

Chemical properties: PVC building shuttering is moisture-proof, water-resistant, acid-resistant, alkali-resistant and other corrosive substances-resistant, and has high surface flatness and good finish, which exceeds the technical requirements of existing plain concrete shuttering.

Flame retardant and anti-corrosive: PVC building formwork has flame-retardant and anti-corrosion functions, which improves the safety of the building.

3. Manufacturing Process

Raw material preparation: PVC resin is pre-mixed and heated to make it flowable, and then various additives are added for complete mixing.

Mold making: Molds are made according to the needs, and then the mixed raw materials are poured into the mold for molding to form a mold.

Further processing: After the mold is made, post-processing, such as chamfering, punching and trimming, is carried out to better apply it in the construction field.

4. Economic efficiency

Low cost: The price of PVC building formwork is relatively low, and the amortization cost is low, which reduces the construction cost.

Long service life: The turnover of PVC building formwork can reach more than 30 times, and it can be recycled and reused, which extends the service life.

In summary, PVC building formwork has become a new and popular construction material with its environmental protection and energy saving, excellent performance, simple production process, economical and practical, and wide application.
