Production Technology of Thermoplastic Composite Building Formwork
Release Date：2026-01-13
Page Views：130
The production technology of thermoplastic composite building formwork ensures that the concrete structure is poured according to the design requirements. It has to bear the horizontal load (lateral pressure of concrete) and vertical load (self - weight of the building formwork, material structure and construction load) during the construction process of the concrete structure.
It is used in large quantities and widely in concrete construction. According to statistics, the formwork usage in every 1m² of concrete project is as high as 4 - 5m². Its project cost accounts for 30% - 35% of the cost of cast - in - place concrete structures, and the labor cost accounts for 40% - 50%, thus playing a crucial role. In 2007, the annual output of various formworks in China exceeded 850 million square meters, making China the world's largest producer of formworks.
Plastic formwork is a new type of energy - saving and environment - friendly product. With its outstanding characteristics like high surface hardness, smooth finish, easy demoulding, abrasion resistance, easy cleaning, light weight, long service life, high specific strength, good toughness, excellent processing performance, convenient construction, recyclability, no pollution, and suitability for fair - faced concrete, it is undoubtedly the leading development trend of building formwork. However, the "bottlenecks" of plastic formwork include relatively low strength and stiffness, poor dimensional stability, low heat resistance, and high cost. Our company has developed a thermoplastic composite building formwork. |  |
