Detailed characteristics of plastic woven bags

作者: Release Date: 2016-07-27 Author: Click:

The materials of plastic woven bags are composed of PP (polypropylene) and PE (polyethylene). In the May Day era, the PP market was relatively mediocre. The response to the deal atmosphere was less ambitious. Xiaobian feels that the slump in the PP market has nothing to do with the peak season of the woven bag market in Puyue to Xuanyue every year. The demand is low and the transaction volume is naturally low. Of course, with the continuous downward adjustment of crude oil prices, coupled with the individual market mentality is not very stable, resulting in a slight decline in the price of the department's PP market, but the overall market changes little, the impact is negligible. In the next few months, the editors felt that there was unlimited room for the PP market to decline. Without special circumstances, the market would remain stable for a longer period of time. Plastic woven bag has the characteristics of light weight, good electrical insulation, good corrosion resistance, easy processing and forming. Plastic woven bags possess certain general characteristics of PP and its own characteristics. plastic woven bag

as follows:

1.Lightweight

PP is relatively light on weekdays. The density of PP woven bags is about 0.9 to 0.98 grams per cubic centimeter. Commonly used plastic braids, if there is no increase in filler, that is the density of plastic. Plastic weaving uses the density of plastic from 0.9 to 0.91 g / cm3. Under normal circumstances, the braid is lighter than water.

2.High breaking strength

Plastic woven fabrics are a kind of flexible and high breaking strength data in plastic products. This has nothing to do with its molecular structure, crystallization level, draft orientation, etc., and it has nothing to do with the type of increasing agent. If the specific strength (strength / specific gravity) ) To weigh the plastic braid, which is higher or closer to the metal material.

3.Good chemical resistance

Plastic woven fabrics have good corrosion resistance to organic and organic matter, which is as follows at 110 degrees Celsius. It has no effect on it for a relatively long time. It has strong chemical stability to solvents, oils, and so on. When the temperature decreases, carbon tetrachloride, xylene, turpentine, etc. can swell on it. Fuming nitric acid, fuming sulfuric acid, halogens and other strong oxides will oxidize it, and it has good corrosion resistance to strong alkalis and acid.

4.Good abrasion resistance

The friction coefficient between pure plastic knitted fabrics is small, the only 0.12 Lord, similar to nylon, at a certain level, the friction between plastic knitted fabrics and its items, with a smooth effect.

5, good electrical insulation

Pure plastic braid is a good electrical insulator. Because it does not absorb moisture, it is not affected by the humidity in the atmosphere, and its breakdown voltage is high. Its dielectric constant is 2.2 to 2.6. It has a high volume resistance and good insulation of plastic braids. That is to use it to make use of insulation materials.

6, environmental resistance

At normal temperature, the plastic woven fabric is practically intact and not subject to water decay. The water absorption rate within 24 hours is less than 0.01%, and the water vapor permeability is very low. At high temperatures, it becomes brittle and easily brittle. The plastic braid does not produce mildew. plastic woven bag

7, poor anti-aging ability

The anti-aging ability of plastic woven bags is poor, especially PP woven bags are lower than polyethylene woven bags. Its aging performance is heavy if itchy aging and photodegradation. Poor anti-aging ability of plastic woven fabrics is an important improvement of it, which affects the service life and field of woven bags.
