PP Hollow Building Formwork Production Line

PP hollow building formwork production line consists of two single screw extruders or single screw plus parallel twin screw extruders, which are coextruded by hydraulic screen changer, mould, setting machine, primary traction machine, annealing furnace, cooling box, secondary traction machine, crosscutting machine and conveyor. The well shaped structure is the most accepted in the market in terms of material consumption and structural performance. Its products have many advantages, such as bright and clean surface, small size error, nailing, planing, corrosion resistance, strong flame retardant and so on.

The products produced by Qingdao PP hollow building formwork production line have more advantages than traditional building formwork:

1. Good water resistance. Even if completely immersed in water for several days, it will not deform due to moisture. Acid and alkali resistant, corrosion-resistant, non rotating, especially suitable for use in inclined environment, such as basement engineering, highway and railway truss pier.

2. Incompatible with cement, high viscosity, easy to demould after construction, and will not be deformed due to cement adhesion.

3. The surface of the plastic formwork is smooth and does not need release agent, which reduces the cost of cleaning and maintenance. The surface of the building used for construction is smooth and flat, and no secondary modification is required.

4. Light weight, high efficiency, easy demoulding, low labor intensity of handling operation and high construction efficiency.

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

6. Low cost. It saves a long time and can be used more than 100 times. In addition, used wood and waste can be recycled, which saves cost and reduces pollution. Compared with the traditional wood formwork, the comprehensive utilization cost is saved by more than 30%.

7. Long service life, reusable. Finally, the damaged plastic formwork can be smashed again, and then processed into new formwork, so as to save resources and meet the requirements of "green industry".

8. Good heat insulation is conducive to shortening the construction period.

9. Wood can be added and welded by various methods, so secondary treatment can be flexibly carried out on the construction site.

10. The processing performance of plastic formwork is good, which can be planed, sawed, nailed and used for wood formwork;

11. The procedure is saved and the construction efficiency is improved. The two surfaces of PP hollow plastic building formwork (smooth surface or pattern surface) have different effects. For example, if the surface of the formwork is removed smoothly after the concrete is placed, the solid surface of the compaction is smooth and smooth, which meets the requirements of decoration and decoration water. Without secondary plastering, it can save time and materials, reduce cleaning and maintenance costs, and reduce the quality of formed concrete. Save time. If a patterned surface is used, it is beneficial to combine with a stucco layer. The main axle pier adopts the patterned surface to meet the requirements of decorative surface and decorative clear water, and because the patterned surface has special light diffuse reflection effect, it avoids the strong light reflection to affect the driver's line of sight, thus forming the safety protection effect.
