Plastic buckets are very common in daily life and have many excellent characteristics. Plastic products can be molded into different shapes to meet people’s daily needs. Plastic buckets will become hard in winter. What is the cause? Follow the editor to understand Take a moment.
Plastic barrels have strong corrosion resistance. Plastics are polymer compounds and the structure between molecules is very close. After a period of use, the performance of plastic barrels will decrease, and its own plasticizer will gradually volatilize, and the surface will be smooth. It will also fall, and the season will be cold, and it will become very hard.
The plasticizer will not dissolve in water and has very little water absorption. It will only dissolve in a high temperature environment above 70℃. Unlike polyethylene, it will melt or solidify with temperature changes between 15-40℃. When the temperature rises, it will absorb heat to melt, and when the temperature drops, it will release heat to solidify. When you feel this change when using a plastic barrel, it is because a plasticizer is used in the production.
These plasticizers can make the barrel smoother. Some plasticizers have poor cold resistance. The smoothing effect will be weak at low temperatures in winter, and they will not be able to rotate sensitively. As a result, the plastic will harden and the temperature will recover.
