Musu composite materials (including products) production process affect its performance Hentai, experiments show that: the ability to process the Bugou cause Qianwei Fensan and invasive Bujun Yun, and too much processing Ze will propel fibers damage and breakage, both of which reduce mechanical properties of wood materials. In addition, to prevent excessive shear or high temperature to produce a paste and so on, one-step continuous process if the devolatilization (mainly dehydration) is not sufficient to affect the next step of processing, and products are air bubbles and performance. Currently, the main processing equipment for single-screw extruder and a twin screw extruder, a twin-screw extruder can be divided into the same parallel twin screw extruder and counter-conical twin-screw extruder.
Counter-conical twin-screw extruder: with parallel twin-screw extruder ratio, different to the conical twin screw extruder is called low-speed, low-power-type equipment, non-modular screw. Conical twin screw extruder with a general ratio, to meet the processing needs of the thermal resin, designed to meet the requirements of the screw a wide range of processing, cut less effect on the wood fiber, resin uniformly dispersed and still came with the material completely melted. Because wood flour, vegetable fiber proportion of small, filled with large, feeding zone volume than conventional models larger, longer. If wood flour, vegetable fiber added in an amount of molten resin rigidity, also requires high back pressure resistance gear box, using compression and melting fast, short-metering section of the screw, to ensure that the wood fiber short residence time to prevent it from breaking and coking paste . The main manufacturers of such equipment for the Cincinatti Milacron companies, including in the United States Extrusion Tek Milacron companies in Germany SMC Corporation Cincinatti branch. In addition, the Italian Bausano company ICMA San Giorgio and in the 1970s began to engage in plastic compounds filled with wood powder processing equipment work.
