Preheat P P material after screening, grinding, drying, metering, mixing, etc after pretreatment with P - P - g MA H and other accessories, additives such as dry mixed together, then add the mesh differential twin screw extruder in plasticizing extruder into another mesh differential twin screw extruder, meanwhile the non-alkali glass fiber (1200 Tex, the enhanced infiltration agent) preheat treatment after melting mixing material blending into the extruder, die extrusion sheet through the nose and passes through three roll calender and cooling conveyor, trimming, traction and cutting glass fiber reinforced pp sheet packing after growth.
Out of rolling forming is one of the main methods of the production of plastic plate. Extruder will material melt plasticization and plastic melt in slit nose shape as the required specifications of the slab, the three-roll calender calender, cooling stereotypes, then through further cooling guide roller, then the edges by trimming machine, after the second roller tractor traction cut into required specifications of the plate.
Through the calculation of material balance, working hours and number of units were determined. Meanwhile, the output of each process, amount of loss and waste were listed. This was also the strong reference adopted to decide the amount of raw materials in the design.
In the content of energy balance calculation, the amount of cooling water and chilled water was decided through the energy calculation of the extruder and mold, further, the specific amount of power consumption in the design was determined.
In the Non-process design, the safety, environmental and other non-technological factors were considered, and the staff arrangements and other related matters were listed.
Through economic accounting, the cost of the design was estimated.
The plant layout design was the final content, in which the principles and requirements of plant layout were briefly introduced. And the specific arrangement of the workshop in the design was illustrated.
