Iranian Experts Manufacture New System to Produce Biodegradable Plastic
“The kneader extruder is one of the world's most up-to-date technologies for producing paste compounds. This device enjoys the capability to combine polymer materials with nano powders for a very long residence time and with much more mixing than a twin-screw machine, creating a completely uniform mixture of nano powder inside the polymer matrix and preventing the formation of lumps or powder clumps inside the polymer,” Mahmoud Bayat, the manufacturer of the asymmetric kneader extruder, told ANA.
Noting that the main reason for the poor quality of most automotive polymer parts is due to improper mixing of compounds, he said, “Production of this technology greatly improves the quality of polymer products from which the automotive and aerospace industries can benefit.”
“This product is widely used in the polymer and plastic industry, and for the first time, this complex has been able to produce nylon which is 80 percent composed of minerals and is biodegradable,” Bayat said.
In a relevant development in December, Iranian researchers at a knowledge-based company had also succeeded in manufacturing a high-torque twin-screw extruder for the production of polymer nanocomposites.
“The high-torque twin-screw extruder has been designed and built for the first time to produce polymer nanocomposites. The device can make polymer nanocomposites and polymer granules on a nanoscale,” Ali Honarian, the managing director of the knowledge-based company, told ANA.
“This device is used in the compound and masterbatch industries,” he added.
“This device, the prototype of which we have now built, is a heavy and complex device and requires a high level of working capital, which is why countries that own this technology only build a limited number of these devices per year,” Honarian said.
