The raw materials made of plastic barrels make it have better performance, not fragile, will not rust, light weight, have many advantages, moisture-proof, strong corrosion resistance, and can contain dangerous goods. Today I will take everyone to understand it briefly. Related performance.
The main raw material for the manufacture of plastic barrels is PE. This raw material meets the sanitary standards for food packaging and is a very important raw material in plastic products. Some users have reported that plastic barrels will become brittle when used, and the brittle barrels will easily be damaged. , Can not be used for long-term use.
The brittleness of the plastic barrel is closely related to the mold, the use of raw materials, and the production equipment during production. If it is difficult to demold during manufacturing, the temperature of the cavity should be increased, and the cooling time should be shortened. The temperature of the cavity should be lowered and the cooling time should be increased; the temperature of the barrel and nozzle is relatively low, so it needs to be adjusted higher to allow the material to be effectively degraded.
If the mold temperature is too high, demoulding is difficult, and the mold temperature is low. The plastic is cooled too early, and the joints are not fused effectively, and there will be cracks; these reasons will cause the plastic barrels to become brittle. The manufacturer should pay attention to avoiding these during production. Question, I hope the above content is enough to help everyone.
