[ Focus on Chemical Machinery and Equipment Network ] Since the beginning of this year, the prevention and control of plastic pollution in China has been continuously strengthened.
Since the implementation of the new "plastic ban", degradable plastic products have become the "new favorite" in the market
.
In the near future, non-degradable plastic products will gradually be completely replaced by degradable plastic products
.
Chemical machinery and equipment network hotspots pay attention to plastic products of chemical machinery and equipmentSince the implementation of the new "plastic ban", degradable plastic products have become the "new favorite" in the market
.
In the near future, non-degradable plastic products will gradually be completely replaced by degradable plastic products
.
After the new "plastic ban" is issued, it is estimated that in the three areas of food delivery, express delivery, and agricultural film, the future demand for degradable plastics will reach 1.
5453 million tons, corresponding to a market value of 27 billion yuan
.
In addition, China’s biodegradable garbage bags and shopping bags have a huge market demand, with an annual output value of up to 12 billion yuan; the demand for bio-based fully degradable inflatable bags is growing rapidly, and the total market demand will reach 37.
3 billion yuan; the bio-based degradable lunch box market The demand is huge, and the annual demand is about 100 billion yuan in the market

Responding to the call of the national environmental protection policy and solving the problem of plastic pollution at the source is the responsibility of every enterprise.
For plastic machinery manufacturers that produce plastic products , they want to make the machine produce degradable plastic products that meet environmental protection requirements, or It needs to go through technical adjustments and upgrades, and even research and development of new equipment to meet market demand and achieve rapid development

A few days ago, an investor asked Yizumi (300415.
SZ): Does the biodegradable plastic PBAT need a new injection molding machine? Can the old injection molding machine be used? Yizumi said: As a new type of material, the biodegradable plastic PBAT does not need to be replaced with a brand new injection molding machine under existing conditions.
It can be put into production only after a certain degree of adjustment on the basis of the old injection molding machine.
, such as: improved iterative molding process or the like of software algorithms

Degradable plastics, especially fully degradable plastic products, have become imperative.
These materials have the characteristics of low processing temperature, which is very close to the degradation temperature, and are easy to oxidize and degrade and are easily affected by moisture.
Once heated for too long, the temperature is too high.
High, it will degrade and cause gel, black plate or yellowing
.
Seriously affect the appearance and performance of the product
.
For fully degradable plastics, the injection molding machine should have new features such as a low residence time plasticizing device, a low-temperature and low-shear high-efficiency screw, a servo oil pump energy-saving system, and a precise temperature and pressure control feedback system
.
For injection molding machine manufacturers, it is time to accelerate the pace of technological transformation and upgrading

The difference between injection molding process and ordinary injection molding:
The injection molding process of degradable plastics and ordinary plastics is quite different.
The reason is that degradable plastics are generally non-Newtonian fluids with poor fluidity, which do not melt at low temperatures and are easily decomposed at high temperatures, so the processing temperature range is relatively low
.
Different degradable raw materials have very different processing techniques.
Taking PHA as an example, the reverse temperature control method can be used, that is, the temperature at the lower part of the hopper is higher than the nozzle temperature.
This method can control the raw materials well.
Melting and loss of molecular weight

Precautions for purchasing injection molding machine:
Ordinary injection molding machines cannot produce degradable materials at all, because biodegradable materials are more sensitive to temperature.
In a low temperature molten state, the fluidity is very poor, causing relatively large pressure on the draw rod and injection piston rod of the injection molding machine, which may easily lead to failure.
Normal molding; or after normal use for a period of time, the performance of the injection molding machine deteriorates significantly, and normal production cannot be performed
.
It is generally recommended to use the "Quick Machine" series servo injection molding machine, which has high mechanical tuning performance and reduces energy consumption, which is conducive to the molding of degradable materials
