XPS conventional production items is on the way to be the sole screw as well as single-screw tandem mode unit. like a end result inside the large cooling ability specifications of extruder, which produces screw pace should only be relatively low, within another hand, the operating theory of single-screw extruder also produces the conventional sole screw inside the combine result has some limitations. using CO2 like a blowing agent, firstly should hold out challenging from the materials itself, that is, to solve the concern of solubility of options themselves, through modifications in options formulations to attain this aim. Secondly, they should increase from the appliance structure. Say developing utilization of <a href="http://www.zhaoxingmachine.com/p-Plastic-extruder-135257/Twin-screw-extruder-135258/">Twin screw extruder</a> which has appreciably much better compounding result than sole screw extruder can help increasing the solubility of CO2 from the GPPS. on the identical time, items should be also adequate to make sure good sealing performance, can withstand increased pressure, this may increase CO2 solubility from the materials, but on top of that can give out increased stress get rid of on the exit inside the slot die so which you can facilitate increased high quality inside the last the foam board.
With long-term near get in touch with and relationship with worldwide well-know raw materials suppliers, say complete and BASF from the different sorts of options we used, we have experienced a deep knowing inside the different material’s overall performance and features from the foam extrusion with CO2. on the identical time our business carried out our know-how in twin screw extruder, and merged the benefit of twin-screw extruder from the XPS production successfully. Meanwhile we available up the brand new method to create XPS in domestic market.
Based on our experience, specifically it is required to hold into account the screw barrel inside the structural pattern to turn out to possess the ability to fulfill the necessities of high-pressure sealing. on the identical time also to fulfill the twin-screw extruder backpressure inside the result of slowdown from the lifestyle inside the gearbox. one more concern is on the way to be the actuality how the blowing agent injection port place choice and pattern of screw framework for that zone can be relatively important. because not just should hold into account the screw framework inside the dispersion effects, but on top of that hold into account that options residence time from the extruder and extruder’s energy intake issues.
