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