The Visual twin screw-extruder in the Institute of Plastic Machinery and Engineering of the Beijing University of Chemical Technology (it is called Institute of Plastic Machinery for short) is the first visual plastic machine in the world .
Our plastic machine industry can take advantage of the opportunity and practice the two strategies on the base oupon thelocal market' s need:local product internationalization and abroad products domesticationalization, in order to meet the challenge of the competition and threaten.
The meaning of the research of this paper:providing the direction and lessons for plastic machine marketers, privding the reference for the research of the industrial product' s marketing, as it' s in weak line until now.
The paper introduces the application of axial varable piston pumps in plastic machines with low energy consumption and of internal gear pumps in plastic machines with low noise level,and whole electromotion plastic machines without hydraulic pumps.
Then a control system based on C8051F005 was designed according to the algorithm,which could monitor the temperature change and the working of the packing machine.
When PCCPE/EVA was 100/15 (mass ratio) , adding plasticizer 5 phr , fillers 100 phr , and mixing at 150°C , the blend compound had following properties : tensile strength 12.5 MPa,elongation 294% and compression set 50% .
As the raw materials supplying plant used in domestic plastics processing factories at the present could not be suited to the high-speed deve- lopment of the plastics products and processing machines,the present condition of raw materials loading and some common types and characteristics of pneumatic conveying equipments in domestic and abroad was introduced, the fundamental principles of pneumatic conveyance were theoretically analized, emphasizing the design and calculation of the pneumatic conveying equi...
The effects of blending machines , open mill and internal mixer , on the mechanical proper ties , rheology characteristics , micromorphology and technique of EPDM/PP thermoplastic vulcanizate (TPV) by dynamic vulcanization method were studied . The results showed that the properties of TPV prepared by open millwere less than those by internal mixer remarkably . It was better to produce EPDM/PP TPV by internal mixer .
