Description

Polylactic acid (PLA), also known as polylactide, is a polyester polymerized with lactic acid as a raw material. Polylactic acid has excellent biodegradability, compatibility and absorption. Polylactic acid is a non-toxic, non-irritating synthetic polymer material. Its raw material is lactic acid, which is mainly derived from the fermentation of starch (such as corn and rice). It can also be obtained from cellulose, kitchen garbage or fish waste. Compared with traditional plastics, polylactic acid can be degraded into CO2 and H2O by microorganisms and light. Its degradation products are non-toxic and harmless, and will not pollute the environment. The monomer producing polylactic acid is lactic acid, and lactic acid can be produced by fermentation of crops or agricultural by-products such as wheat, rice and sugar beet. Therefore, the raw materials for the production of polylactic acid are renewable. As an emerging biodegradable material, polylactic acid has a wide range of applications.



Degradable material granulator polylactic acid (PLA) starch plastic granulation equipment features detailed description:

1. Single screw granulator for degradable masterbatch. The screw is designed and manufactured according to the principle of building blocks. According to the requirements of the processing material system and process formula, its length to diameter ratio, barrel structure, screw arrangement, screen changing structure, exhaust quantity and position, feeding method, electrical control method, etc., can be optimized and reasonable. Configuration. Realize multi-function and multi-purpose to adapt to processing polymer materials.
2. The new deceleration distribution transmission system of the degradable masterbatch granulator, high-torque design, high-precision gear processing, imported parts for main bearings, reasonable oil-immersion lubrication combined with forced lubrication devices for key parts, and interlocking protection devices to ensure The host runs reliably and smoothly.

3. The degradable masterbatch granulator makes full use of the limited space to design the involute spline structure mandrel to ensure the bearing capacity and realize high torque transmission.

Processing and production process of degradable masterbatch granulator:

Internal mixer-hoist-cone double feeder-single screw granulator--opposite blowing hot cutting head-first-stage cyclone separator-second-stage cyclone separator-extended air-cooled vibrating screen ——Finished product silo.

Among them, the bulk material of the internal mixer enters the double-wrist feeding port through the elevator, and is extruded, pelletized, cooled, sieved, and the terminal silo is fully automated. The material can be forced into a single screw after banburying. The full name of the screw is dispersed, without excessive friction heat, and the dispersion effect is excellent.

The performance of the degradable masterbatch granulator: high efficiency and energy saving: the power consumption is 60% of the whole machine in normal use.  Environmental protection: The working equipment in the early stage is a sealed working environment, and the later stage is a group state, which reduces the production and now dust is flying around.

The degradable masterbatch can reinforce the resin component or base material in which fibers or other reinforcing materials are dispersed in the plastic. The continuous phase in the composite material is called the master batch or base material. When manufacturing plastic products, there is no need to add this kind of plastic additives, but only need to add the corresponding degradable masterbatch.

When manufacturing plastic products, there is no need to add this kind of plastic additives, but only need to add the corresponding degradable masterbatch. Therefore, it is one of the most important forms of application of plastic additives in the world today. Its advantages are: simple process, convenient use, easy to realize production automation, increase labor productivity, avoid environmental pollution, and be conducive to clean and civilized production of workers' health.

The degradable masterbatch is suitable for traditional processing techniques such as film blowing, casting, blister molding, wire drawing, bottle blowing, and injection molding. It is widely used in applications such as disposable plastic packaging films and containers that need to be degraded, such as household garbage bags, food preservation bags, supermarket shopping bags, food roll bags, disposable lunch boxes, disposable beverage cups, simple tableware, Instant noodle bowls, agricultural mulch film, industrial packaging film, plastic packaging bottles and other plastic applications.
