SJSZ65/132 Twin screw extruder PVC profile production line for door panel

Application:

Plastic profiles are used more: window frames, stair railings, wire troughs, skirting boards, shaped tubes, furniture, building materials and other accessories. The raw materials are mainly hard PVC, and a few are semi-hard PVC, soft PVC, polyurethane low foam and other materials.
For hard PVC plastic profiles, there are disadvantages of poor impact resistance, which are often modified by adding ACR, CPE, EVA, MBS, etc. to improve the impact strength. CPE (chlorinated polyethylene), EVA (ethylene-vinyl acetate copolymer), ACR (acrylate), MBS (methyl methacrylate-butadiene-styrene graft copolymer) are generally added in an amount of 6% to 10 %. MBS is mainly used in transparent plastic profiles. EVA is best not shared with lead stabilizers. It has poor moldability and powder spots when used. CPE is best not shared with zinc stabilizers, and the low temperature of CPE is not. Great.

When producing plastic profile products, process conditions such as temperature, screw speed, traction speed etc.

Features specifications:

Extrusion: Also known as extrusion molding, it is mainly suitable for the molding of thermoplastics, and is also suitable for the formation of thermosetting and reinforced plastics with better fluidity. The molding process uses a rotating screw to extrude the heated and melted thermoplastic material from a machine head having a desired cross-sectional shape, and then shaped by a sizing device, and then chilled and hardened by a cooler to obtain a desired cross section. product.
