Principle of Production
Typically,the production line is to produce 3 layers(ABA)hollow construction formwork. Adopting three layer distributor and co-extrusion technology, the material pp(or recycled pp) and other additives go through a complete production in which all these materials heated,mixed,sheared,and co-extrudered in single screw extruders to finally form the three layer pp hollow formwork sheet in the T-die mould whose thickness can be adjusted,then the extruded 3 layer sheet is hauled forward to a calibration station where it is cooled andvacuum calibrattheed for certain shape,and finally cut and stacked.Flowchart for PP Formwork Production Line
Engineering Drawing and Equipment List
PP Hollow Formwork Advantage1.Light in weight, high strength,high hardness, impact resistant, tear resistant.
2.Surface is smooth,bright and clean,then to make the concrete block surface smooth.3.Good concrete forming.
4.Moisture absorption,no deformation,mildew resistant,steady in size,especially suitable for underground and damp environment.
5.Acid and alkali resistant, corrosion resistant, preservative treatment is not required both during use and storage of formwork,and will not make any pollution.
6.The reusable time for pp hollow sheet can reach more than 50 times,long service time.
7.Eco-friendly,can be recycled to granulate to feed as raw material.PP Hollow Construction Formwork Comparing to other Construction Sheet
Aftersales Service1.Technical documentsAll the symbols on the equipments should be in English.
