What Technical Points Should Be Paid Attention To In The Production Of Plastic-wood Floor Materials

Now the market of plastic wood flooring sales are very fast, and the future market will be further expanded. On the one hand, it brings more business opportunities to manufacturers, but at the same time, it also puts forward higher requirements for the production process. The following two points should be paid attention to in the production process of wood-plastic composites: First, the influence of temperature on the processing and forming properties of wood-plastic composites. Barrel temperature and head temperature have great influence on the extrusion process of wood-plastic composites. The barrel temperature plays a decisive role in the mixing and plasticizing effect of wood-plastic composites. The temperature of the die has a crucial influence on the extrusion of wood-plastic composites. On the premise of satisfying the plasticizing quality of materials, the die temperature of extruder should be lowered as far as possible. The die temperature is very important for the extrusion of wood-plastic composites, and it plays a controlling role in the quality of extrusion. Secondly, the influence of rotational speed of wood-plastic composites in the process of processing and moulding. Increasing the screw speed can increase the extrusion output of plastic wood, improve the production efficiency and reduce the production cost, which is the goal of modern industrial production. When the high speed is used, the material is not fully cooled after being ejected, which makes the cooling of the product uneven, resulting in varying degrees of ripple on the surface of the product, the appearance and quality of the product will be affected, sometimes the product can not be formed, so that production is forced to discontinue and the continuity of production is destroyed. When the rotational speed is very low, the material moves forward in a laminar flow situation. The material can be fully cooled before setting. The surface of the product after the export die is very smooth and the appearance quality is very good, but this will reduce the output.
