Degradable plastic refers to a kind of plastic whose products can meet the requirements of use and whose performance remains unchanged during the storage period but can be degraded into environmentally sound substances under natural environmental conditions after use.

PLA industry chain.

1) Upstream: The raw material is mainly crushed corn and other shell crops, and then starch is extracted from it, and then the starch is made into unrefined glucose.

2) The production includes three steps of "fermentation-prepolymerization-polymerization". The first step is to ferment glucose in a manner similar to the production of beer or alcohol to obtain lactic acid with high optical purity. In the second step, the lactic acid monomer is transformed into an intermediate product-water-reduced lactic acid, or lactide, through a special concentration process. In the third step, the lactide monomer is vacuum-purified, and then a solvent-free dissolution process is used to complete the ring-opening action to polymerize the monomer.

Bio-based degradable plastics represented by PLA are mainly derived from food and microorganisms, with renewable sources, no pollution to the environment after use, and conform to the national sustainable development strategy, although the current raw material costs, technology, and equipment costs are relatively high. But with the further development of the technological level and pla extruder machine scale, the cost has decreased correspondingly, and the development prospects are bright.

The sudden epidemic spread all over the world in 2020, which makes people pay more attention to the medical and health problems. Jwell as medical extrusion companies specializes in providing all kinds of medical extrusion equipment, such as EVA, PVC infusion bag, waste liquid bag production line, PP melt-blown cloth production line, PE breathable film production line, PVC, PP, PE endotracheal intubation/precision infusion production line, etc.

The medical plastic production extrusion line has the advantages of high output, low energy consumption, convenient operation, etc., and our company can make special customization to meet your different needs. Welcome to contact me for consultation.

EVA medical film produced by eva extrusion is widely used: EVA is a new type of polymer material, because of its stable physical and chemical properties, good elasticity and toughness, easy processing, high light transmission, corrosion resistance, non-toxic, odorless, pollution-free, etc. At present, it has been widely used in the field of food and medical consumables (such as nutrient solution bags, blood transfusion bags, etc.), and has become a new generation of medical and food packaging materials that are generally trusted and respected internationally. The bag body made of EVA material is transparent, and the scale is clear, which is convenient for observing the position of the liquid surface.

JWELL is professional manufacturing the parallel twin screw extruder, over the years company has been committed to with co-rotation parallel twin-screw extruder and auxiliary equipment Research & Development, has been completely leading with their competitor in a special polymer materials application.

Such as Engineering Plastics Pelletizing, High Filler Pelletizing Line, PET Flakes Recycle Pelletizing, Petrochemical Powder Pelletizing, Thermoplastic Elastomers Pelletizing, Silicone Adhesive Pelletizing, PU/TPU Reaction Pelletizing, Masterbatch Pelletizing, WPC Pelletizing, Functional Extruder, Lithium Battery Extruder and so on, Continuously provide customers with better quality, more reliable and more human-oriented in the co-rotation parallel twin screw compounding extruder machine.

Types of compounder machine

Twin Screw Compounder CJWA/CJWH SeriesTwin Screw Compounder CJWA/CJWH Series

The twin screw extruder is developed on the basis of the single screw extruder. Because of its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability, etc., it has been widely used in extrusion products for molding processing.

PVC Twin Screw ExtruderPVC Twin Screw Extruder

Typical materials: PVC cable material, PVC transparent material, PVC blood transfusion pipe material, low smoke low halogen or low smoke halogen free cable material, all kinds of PE crosslinking materials, and rubber dehydration after treatment.

PET Recycle Compounding LinePET Recycle compounding line

At present, the collection, packaging, sorting, grinding, cleaning, drying, extrusion, filtering, chipping and solid-state polymerization processes of PET bottle flakes all create the possibility of efficiency improvement and the resulting cost savings.

Masterbatch ExtruderMasterbatch Extruder

The heating of the machine adopts the method of resistance heating extensively, and the thermocouple is used to realize the segmented temperature control and side detection. Resistance heating uses resistance to generate heat to heat the barrel, and then transfer the heat to the plastic in the barrel.

plastic compounding machine gearbox is a very important part, and its structural design directly affects the normal operation of the entire machine system. Because the gearbox of the parallel twin-screw extruder relies on the large thrust of the output shaft for rubber mixing, the center distance of the two screws is relatively small, and the output structure requires high rotation accuracy, so it is difficult to design and process this product.

Twin Screw Compounding Extruder CJWS Super-high Torque SeriesTwin Screw Compounding Extruder CJWS Super-high Torque Series

Twin Screw Compounding Extruder are widely used in the filling, blending, modification, reinforcement of rubber, plastics and engineering resins.

Co-rotating Twin Screw Extruder CJWV Large Volume SeriesCo-rotating Twin Screw Extruder CJWV Large Volume Series

There are two screws arranged in parallel barrel, the spirals of which are tangent or meshed, and the screws can rotate in the same direction or in the opposite direction. It is suitable for processing heat-sensitive materials such as hard polyvinyl chloride. It is also suitable for mixing ingredients, such as the ingredients of glass fiber reinforced PBT, light polyolefin molding powder, and the ingredients of poorly compatible mixtures such as wax and resin.

Advantages of Compounding Machine

Easy To Open

you can find the degree of wear of the threaded element and the inner liner of the barrel at any time.

Reduce Manufacturing Cost

Compounding machine only takes a few minutes to quickly open the barrel for manual cleaning, so that you can use less or less cleaning materials and save costs.

Improve Labor Efficiency

High Torque, High Speed, High Output, High Quality. Reduce maintenance time and labor intensity.

Wide Range Of Applications

We have a wide range of applications and can be applied to the processing of a variety of materials.

Fuctions of Compounding Machine

Extruders from extrusion line are one of the most important component which is used in the manufacturing process. Whenever these are combined with feeding, cutting, de-airing or other form of equipment it can create everything. There are various types of extruder machines about which one must know. So scroll down to learn more.

The twin-screw extruder produced by Jwell machine is mainly used for filling, blending, modifying, adding, chlorinating, polypropylene, and super absorbent resin processing of rubber, plastics, and engineering resins; degradable masterbatch, polyamide polycondensation, polyurethane addition Extrusion of polymerization reaction; granulation of carbon powder and magnetic powder, preparation of insulating materials, sheath materials for cables, low-smoke halogen-free flame-retardant PVC cable materials, and various silane cross-linking materials, etc. Small models are mainly used for scientific research And teaching.

Working Principle of Compounding Machine

The working principle of the twin-screw extruder is the same as that of the single-screw extruder. The processes of transportation, melting, pressurization, pumping, mixing, peeling, and devolatilization are all completed by the twin-screw extruder. In recent years, the study of twin-screw extrusion theory has shown that the geometry of the screw and the extrusion process are very complicated, which brings many difficulties to the research.
