Among all the tarps made of different materials, PE tarps should be considered as a large amount of use, and its production material is polyethylene PE.What are the characteristics of polyethylene, the production material of PE tarps?

 

Polyethylene is a typical thermoplastic, odorless, tasteless, non-toxic flammable white powder. Molding processed PE resin are extruded granulated wax-like granular material, the appearance of milky white. The melting point is 100-130 ° C, its low temperature resistance is excellent, the use of temperature up to -100 ~ -70 ° C. In -60 ° C can still maintain good mechanical properties, but the use of the temperature in the 80 ~ 110 ° C. The chemical stability is good, room temperature, the use of the temperature in the 80 ~ 110 ° C. The chemical stability is good. Chemical stability is good, room temperature resistance to dilute nitric acid, dilute sulfuric acid and any concentration of hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, acetic acid, ammonia, amines, hydrogen peroxide, sodium hydroxide, potassium hydroxide and other solutions.

PE tarpaulin raw materials generally refers to color striped cloth, is coated with PE film on both sides of PE woven cloth, also used in polypropylene woven cloth, its production process is: wire drawing - round woven cloth - double-sided film. This tarpaulin waterproof performance is poor, generally used once will not dare to guarantee the waterproof performance, the disadvantage is easy to wear, the advantage is that its quality is light, clean and non-polluting. Generally used in temporary stockpiling rain and dust with, not suitable for long-term use in the open air environment.

How to reduce the damage of PE tarpaulin?

Storage conditions: the storage place must be ventilated, aerated, light, clean, adhere to the air circulation during the day, rainy days should be closed doors and windows to ensure that the items are dry, to avoid moisture.

The storage area is divided into: to be processed area, good products area, and defective products area. Items should be stacked up and down to do "on the small under the big, on the light under the heavy". Storage should adhere to the three principles: fire, water, pressure; fixed point, quantitative; first in first out. Warehouse items to room temperature environment storage. Moisture-prone items, prohibit direct placement on the ground, should be placed on shelves or pallets to block. Now common double-pole tent, when supporting the tent poles, is two poles at the same time; close the tent when the tent will be sand, debris pouring clean; set up a tent when the choice of campsite is more important, the ground as much as possible do not have too many sharp objects; try not to cook inside the tent; in order to protect the tent, you can lay a piece of ground cloth under the tent first; under the tent pegs, the first under the tent's two diagonal corners, and then under the other two diagonal corners. This way the tent is more level.
