Description: PLA is an industrial biodegradable material that is extracted from corn or other raw materials that are recycled once a year. PLA is known for its excellent transparency, high gloss and good barrier properties, and has properties similar to polypropylene oxygen barrier properties. PLA is produced by using the heat absorbed by plants from the air during photosynthesis, and stored as grain starch, which can be broken down into natural plant sugar (glucose) later, when the main cause is the carbon content of natural plant sugar Natural plant sugars are converted into polylactic acid (PLA) through a process of fermentation, distillation and polymerization.
PLA is a material extracted from plant starch. It is a plastic degradable material. In a warm (50°C-60°C) humid environment containing microorganisms, PLA can decompose within 75-80 days.
Features of PLA: 1. It can be biodegraded in the natural environment and will not cause harm to the environment.
2. The material has good stability and can be processed by various processes.
3. Good biocompatibility, gloss, transparency, hand feeling and heat resistance.
So we often use air cooling conveying belt equipment to produce this kind material.
The air-cooled strand granulation system consists of an air-cooled steel mesh conveyor belt and a granulator.
Principle of air-cooled strand pelletizing system: The strands extruded by twin-screws fall on the air-cooled steel mesh conveyor belt. There are more than ten fans on the conveyor belt, which cool the extruded plastic strips one by one, and then send them to the granulator. Complete the granulation of air-cooled raw sliver.
Characteristics of the air-cooled billet drawing and cutting system:
1. The cost of the air-cooled billet drawing and cutting system is low and the equipment is simple. Low maintenance costs.
2. The production line of the air-cooled strand granulation system is relatively long, generally 15m~20m
3. The air-cooled strand granulation system is suitable for a variety of materials, and the granules produced do not contain water.
Work Flow:
Advantage: Nine Delong Extrusion machine price belongs to the middle and low price in the industry. What benefits can our equipment bring to customers? Our equipment can bring the following benefits to users:
1. Features: The host of this equipment is environmentally friendly; the host equipment does not need to be connected to the external circulating water system; the self-contained circulating cooling system is a patented product of our company.
2. Twin-screw gearbox cooling adopts: environmental protection cooling system (environmental protection type: invention patent number: CN201911312134.6) does not need to be connected to external circulating water for cooling, and there is no need to wander outside water; the closed-loop circulation system is adopted, so there is no need to worry about using water for cooling for a long time Scale will block the cooler and cause damage to the gearbox
3. The water tank cooling system of the twin-screw main engine adopts: adopts an environmentally friendly cooling system (environmental protection type: invention patent number: CN201911312134.6) does not need to be connected to external circulating water for cooling, and does not need to wander outside water; adopts a closed-loop circulation system
4. Energy saving: normal cylinder cooling; for example: the temperature in zone 5 is too high; this is the conduction of the electronic valve; the cooling return water in zone 5 will affect the temperature drop in zone 6 and zone 4; it will lead to Heating in the fourth and sixth areas; this situation will continue to recur; resulting in waste of electricity costs; we now completely solve this problem by adopting an environmentally friendly type; plus we entrust a third party to develop a temperature control module, and the temperature control heating system is more energy-efficient than similar equipment: 15 -20% of the electricity bill means that each ton can save customers 10 yuan in electricity bills, and about 30,000 yuan in electricity bills per year
5. Double-screw gearbox adopts: high-torque D-type gearbox, high output.
