分析了目前國產(chǎn)聚氯乙烯樹脂塑化性能差的主要原因亚洲av色噜噜，介紹了其塑化性能改善的機(jī)理www在线免费观看毛片，論述了聚氯乙烯樹脂塑化性能改善進(jìn)展現(xiàn)狀及發(fā)展方向。

The plastic go down the hopper smoothly and is gripped by the thread of the screw. It is forced to go toward the direction of the gear end along with the rotation of the screw. A mechanical transferring process is formed. During the running of the plastic from the feed port to gear end, a high pressure is formed in the process of plastic curing due to the gradual decreasing of the thread depth and the resistance of filter gauze, splitter plate and gear end. The high pressure helps to press the raw material and improve its heat conductivity performance and the quick melting of the plastic, at the same time, the gradual increasing pressure can help the gas which is among material particles exhausted from the air holes.

Based on analysis and compare of all kinds of precept-sorting of feature of plastic product for the different structural plastic product, a 3D feature library of plastic product was built on the platform by integrating Feature-Modeling technique with parametric technique. The feature schleps its information of non-geometry by database-externed technique of the entity. After building the database of plastic material, the module of choice of plastic material is developed by technology of ODBC. The plastic product can be sculpted by calling of feature of plastic product and inputting parameters interactively.
