Plastic woven bag placement and maintenance

The advantages and performance of woven bags are becoming more and more widely known, in the mass production and large consumption at the same time, the usual simple maintenance of woven bags, placing taboos also need to understand, how to reduce the aging of woven bags to a certain extent, extend the service life? Let's first look at the monitoring of the anti-aging effect of woven bags.

Plastic woven bags are composed of polypropylene bags and polyethylene bags according to the main materials; According to the sewing method, it is divided into seam bottom bag and seam bottom bag. At present, it is widely used as a packaging material for fertilizers, chemical products and other items. The aging resistance of plastic woven bags can be measured by artificial accelerated aging test and outdoor exposure weathering test. Artificial accelerated aging experiment is to place the plastic woven bag test sample in the test equipment, which can be simultaneously or alternately affected by light, oxygen, heat and humidity and other factors, under such conditions, the main environmental parameters can be easily maintained relatively stable, so the obtained data can maintain good repeatability.

Plastic woven bags placed according to the UV accelerated aging test qualified products, in the real use of the environment, the anti-aging effect will be different, especially in the case of adding filler to add blocked amine light stabilizer, its anti-aging effect is unstable. Although the outdoor exposure test of woven bags takes a long time and has a large investment in manpower and financial resources, the obtained test data basically meet the practical requirements, and can be used for anti-aging quality evaluation and anti-aging effect monitoring of woven bags.

In the daily use of woven bags, the external conditions such as the ambient temperature, humidity and light of woven bags directly affect the service life of woven bags, especially when placed in the outdoor open air, the invasion of rain, direct sunlight, wind, insects, ants and mice will accelerate the destruction of the quality of woven bags. Flood control bags, coal bags placed in the open air, etc., need to consider the anti-ultraviolet anti-oxidation capacity of the woven bag itself. Ordinary woven bags used by families or workers and farmers must be placed indoors in a place free from direct sunlight, dry and free from insects, ants and mice. And maintenance
