PVC wood plastic composite extrusion molding and ordinary hot plastic material extrusion molding of difference: because in the material joined lots of plant fiber which makes the material flow properties and processing performance variation. Mixing and extrusion molding difficulty. To in the composite system of maintaining and improving the mechanical properties of the materials. And through a variety of methods to improve the plant fiber and PVC resin compatibility. Improve the interface state. Proper coordination of the relationship between them is not increased, and the processing cost relates to many affecting factors. Such as: modifier varieties of lubricant dosage varieties, stabilizer varieties, dosage, formulation of rationality. The influence factors of PVC wood plastic composite material extrusion molding many of the text only in process control are discussed.
In the production of PVC wood plastic composites to changes in process conditions is the most complicated. In operation, besides should have a reasonable formulation, molding machine process control (process) is very important. The key variables affecting the yield and quality: screw speed, material Jane temperature, mold temperature, vacuum forming, wood plastic composite material traction speed. The causes of plastic profile extrusion molding, abnormal phenomena and solutions.
On the rationality of PVC wood plastic composite products with emphasis on ingredients and process. In addition to the abnormal phenomenon of reason and self-determination way outside. Unpredictable factors there are many. To achieve the highest Bo the most and best quality. The key is human factors. This full day out of the importance of practical experience.
