1.sheet twin screw extruder
2.filling volume can reach 50-65%
3.high extruding rate
4.excellent venting performance
Sheet Twin Screw Extruder
Main Raw Materials:
Starch, PCL, PBS, PLA, ethylene / acrylic acid copolymer (EEA) bentonite, light / oxidation degradation materials, process additives etc.
Edible corn starch is main material of Biodegradable starch-base materials, with degradation additives, through blending, polymerization then form new biodegradable starch-based materials, has excellent biodegradable properties and processing performance.
SHJ series Twin-screw degradable sheet machine features:
1. Domestic initiative advanced high-efficiency mixing extruding sheet machinery, which mainly used for high-filling corn starch degradable sheet (filling volume can reach 50%-65%).
2. This machine has unmatched superiority than traditional sheet machine for good feeding performance, high extruding rate, excellent venting performance, low energy- consumption, uniform output, high-precision of three roller pressure, tidy trimming, good winding effects, wide adjustment, is a perfect equipment for high-filling polymer materials final to become sheet.
3. The high-speed co-rotation gear, main machine screw and barrel are all designed by building block system. Charging barrel consist of many sections of barrels, have two venting sets.
The main machine structure can be adjusted according to different materials and technological requirements. It can perform transmitting, mixing, plasticizing, shearing, venting, non-stop automatic screen changing, voltage buildup, extrusion, rolling, trim, winding and other technical process. Wisely solved the contradiction of generality and profession that normal machine can’t get, decrease cost in a large scale.
