What is the production process of the biodegradable plastic extruder?

For directly raw and modified waste plastics, the processing equipment mainly includes single-screw extruder, twin-screw extruder and biodegradable plastic extruder. The waste is melted and plasticized by an extruder, extruded into strips, and cut into pellets directly or after cooling according to the required specifications. The extrusion granulation process is extrusion granulation process control, raw material pretreatment, temperature control, pressure control, impurity filtration and other processes.

How to use biodegradable plastic extruder correctly?

In order to protect the casing of the biodegradable plastic extruder gearbox, the following must be done:

1. After the biodegradable plastic extruder is used for the first time for 500 hours, replace the lubricating oil once;

2. The oil level of the biodegradable plastic extruder is not lower than the center line of the oil mark during normal operation. If it is lower than the center line, please add it quickly;

3. Change the oil every 3000 hours after the biodegradable plastic extruder is used;

4. When changing the oil, the biodegradable plastic extruder should clean the box and the oil filter. After clarifying the lubricating oil used this time, put the clean lubricating oil on the box again, clean the box once, and then release it. Refill with new lubricating oil;

5. The lubricating oil filter should be cleaned every month during normal use, and the lubricating oil filter should be cleaned every week during the running-in period. To clean up, find the oil filter, open it, and remove the dirt.

What should be paid attention to before the production of biodegradable plastic extruder?

1. When operating the machine, the operator cannot stand in front of the biodegradable plastic extruder to avoid accidental injury to the operator. When feeding, strictly prevent metal impurities in the raw materials and hard objects that damage the machine, such as small operating tools, from falling into the barrel. Gloves are not allowed when operating rotating machines to prevent involvement in injury.

2. Check and add lubricating oil in the reduction box and air compressor, and check the lubrication of various mechanical transmission parts. Avoid dry operation damage to the machine and make noise.

3. When starting the biodegradable plastic extruder operation, you must first check whether the power supply wiring is disconnected or leaking; check whether the instrument is damaged or not. Before starting the machine, ensure that all components are safe and normal, so as not to affect production and cause accidents.

4. In the range of film forming conditions, increase the molding temperature, cooling air temperature and inflation ratio; then the haze of the film increases and the gloss decreases; otherwise, it increases.

Take the biodegradable plastic extruder as an example: The barrel and screw of the extruder are made of high-quality alloy steel, which is nitrided and precision machined to have the best hardness and corrosion resistance.

Blown film method: The bottom blowing water cooling method is adopted to make the film achieve high transparency.

The coiling device adopts pressure friction coiling or center coiling, and adopts torque motor adjustment, so that the coiling is smooth and the coil is easy to change.
