Gwell machinery specializes in manufacturing PP new hollow building formwork production line, which is a patent number (zl201810213646.6) successfully developed by our company by absorbing and digesting domestic advanced extrusion technology and independent invention and innovation. This unit has two single screw extruders or single screw plus horizontal twin screw extruders. After CO extrusion, it passes through hydraulic screen changer, mold, shaping machine, primary tractor, annealing furnace, cooling box, secondary tractor It is composed of crosscutting machine and conveyor, and provides a full set of production equipment for many enterprises at home and abroad. In the industry, the original O-shaped hollow structure is changed to meter shaped, V-shaped, n-shaped, well shaped, etc., and to well shaped. The well shaped structure is accepted by the market in terms of material consumption and structural performance. Its products have smooth surface, small size error, nailable, planable, corrosion-resistant, flame-retardant and many other advantages. Compared with traditional formwork, building formwork has the following characteristics:

1. Good water resistance. Even if it is completely immersed in water for many days, it will not deform due to dampness. It is acid and alkali resistant, corrosion-resistant, and will not rot and rust. It is especially suitable for basement engineering, highway and railway bridge piers and other wet environments.

2. It is incompatible and sticky with cement, so it is easy to demould after construction, and it will not deform due to cement adhesion.

3. The surface of the plastic formwork is smooth and bright, and there is no need to brush the release agent, which reduces the cleaning and maintenance costs. The surface of the building constructed with it is smooth and flat without secondary decoration

4. Light weight, high efficiency, convenient formwork erection and removal, low labor intensity of handling operation and high construction efficiency.

5. High support strength, not easy to deformation, impact resistance and wear resistance.

6. Low cost. The service life is long, and the turnover and use times can reach more than 100 times. And the waste boards and leftover materials after use can be recycled to save costs and reduce pollution. Compared with traditional wood formwork, the comprehensive use cost can be saved by more than 30%.

7. Long service life and repeated use. The damaged plastic formwork can still be crushed again and reprocessed into a new formwork, which saves resources and meets the requirements of "green industry".

8. Good thermal insulation, which is conducive to shortening the construction cycle.

9. Various treatments can be carried out by adding wood, and welding can also be carried out, so secondary processing can be carried out flexibly on the construction site.

10. Plastic formwork has good machinability, which can be planed, sawn, nailed, and used simultaneously with wood formwork;

11. The process is saved and the construction efficiency is improved. The two surfaces (smooth surface or patterned surface) of PP hollow plastic building formwork have different application effects. If the smooth surface is used, after the formwork is removed after the concrete pouring is completed, the surface of the tamping body is smooth and bright, meeting the requirements of finishing and decorative water, without secondary plastering, saving materials and time, reducing the cleaning and maintenance costs, and the quality of the concrete is stable after forming, saving the construction period. If the decorative surface is used, it is conducive to the combination with the plastering layer. In particular, the use of decorative surface on bridge piers not only meets the requirements of finishing and decorative water, but also because the decorative surface has a special light diffuse reflection effect, which avoids strong light reflection from affecting the driver's line of sight and plays a role in safety protection.

In a word, plastic formwork has the commonness of conventional building formwork and more characteristics than conventional formwork. Plastic formwork will become an ideal product for global construction in the 21st century to replace wood with plastic, steel with plastic and bamboo with plastic.
