After absorbing foreign advanced extrusion technology, our company cooperating with the Chinese Academy of Sciences successfully researched PE, PP plastic building templates production line. The plastic building templates is made from recycled PE/PP material, fly ash, wood flour fiber, calcium carbonate and other fillers. The thickness of the template will be 8-18mm; the width will be 915-1220mm. This production line equipped with world famous units, combined with our several years' experience of plastic board producing technology, now our production line can make the template has following advantages: clean surface, low deviation, low cost, light weight, can be used 15 -30 times continuously, waste material can be re-used. Now it replaces steel templates and bamboo offset. After a little change, this production line can produce PE plastic foaming board and sheet.
This production line consists of single screw plastic extruder, vacuum automatic feeding unit, dehumidifiers drying hopper, sheet die, 3 roller-ray unit, heating and leveling unit, roll cooling unit, edge cutting unit, traction, shearing unit, roller conveyor unit. With the characteristics of compact structure, superior performance, Screw and barrel optimized design and use of high-performance alloy 38CrMoAiA professional processing which ensure that the whole production line uniform plastics hand stable extrusion, high yield, long life and other advantages. The barrel uses casting aluminum heater heating, wind cooling and precise electronic temperature control instrument; Precise sizing and roller-ray unit to adjust the template good shape; Cutting unit adopt the fixed-length cutting to ensure the accurate length.
The working flow of the PE, PP plastic building templates production line:
1. The process of the recycling material.
First divided into different type, such as PP\HDPE\LLDPE\LDPE\PVC. Then crushing, cleaning and drying.
2. The regeneration of the recycling material
Put various fillers and additives into recycling materials according to different formula. And then use single screw extruder make granule for standby.
3. The produce of the plastic building template.
With different material using different formula to produce kinds of templates.
4. The analysis and quality controlling process.
The accurate analysis of the recycled material and renewable material which is the precondition of the next step process, after quality inspection, the template can be sent to market.
The characteristics of the PE, PP plastic building template:
1. Good water resistance.
The board won't rot; rust and deformation, even soak in the water for several days.
2. It can easy separate with cement, and not deformation because of cement conglutination.
3. It can improve the effect of construction. To create the smooth surface so as to avoid second modifies.
4. It can be produced with different patter to reduce the process of construction.
5. Low weight and easy to use.
6. Long life-time, can be used so many times. The old templates can be crushed again to make new one, save material and protect environment.
7. Good insulation will help shorten the construction period.
8. Wood can be added to the template and use various of treatment methods, can be welding, it also can be flexible secondary processing at the construction site
