The nature of tarpaulin raw material PE

At present, most of the plastic tarpaulins in the plastic tarpaulin wholesale market are made of PE, and the main properties of this kind of PE are:

1) Polyethylene is prone to photo-oxidation, thermal oxidation and ozone decomposition, and is prone to degradation under the action of ultraviolet rays. Carbon black has an excellent light shielding effect on polyethylene. After being irradiated, cross-linking, chain scission, and formation of unsaturated groups can occur.

2) Polyethylene has excellent chemical stability. It is resistant to corrosion by various chemical substances such as hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, potassium hydroxide, etc. at room temperature, but nitric acid and sulfuric acid are more resistant to polyethylene. Strong destructive effect.

3) Polyethylene will age, discolor, crack, become brittle or pulverize under the action of atmosphere, sunlight and oxygen, and lose its mechanical properties. At the molding processing temperature, due to oxidation, the melt will be reduced, discoloration and streaks will occur. Therefore, attention should be paid to the molding processing and use process or material selection. Because polyethylene has the above characteristics and is easy to process and shape, the recycling of polyethylene has far-reaching value.

The safe use of tarpaulin mainly includes the following four items:

1. The tarp should be collected when not in use, and all parts and accessories should be collected completely. Don't lose anything, and avoid missing parts when using it next time, and can't cover things well. At the same time, it is necessary to do a good job of cleaning the tarp. After the tarp is used, if it is not used for a period of time and needs to be put away, the tarp should be briefly arranged. In order to prevent objects from decay in the tarpaulin, it will corrode the tarpaulin at the same time.

2. When transporting the tarpaulin, please handle it with care, and ensure that it is placed in a safe position, avoid high-temperature storage, and strictly prohibit fireworks.

3. Before using the tarpaulin, read the instructions for use first, and then install the tarpaulin. During the installation process, pay attention to the details of installing the tarpaulin.

4. The tarpaulin that has been stored for a long time should be exposed to the sun frequently to avoid the propagation of bacteria on the tarp, which will have a certain impact on the service life of the tarp.
