The use advantages and performance of plastic woven bags are becoming more and more widely known, in mass production and mass consumption at the same time, the usual simple maintenance of plastic woven bags, placing taboos also need to understand, how to reduce the aging of plastic woven bags to a certain extent, extend the service life? Fangyuan packaging and let's take a look at the monitoring of the anti-aging effect of plastic woven bags.
At present, it is widely used in express packaging, fertilizer, cement, rice, chemical products and other packaging materials. The aging resistance of plastic woven bags can be evaluated by artificial accelerated aging test and outdoor exposure weather resistance test. Artificial accelerated aging experiment is to put the plastic bag test sample in the test equipment, can be simultaneously or alternately affected by light, oxygen, heat and humidity and other factors, under this condition, the main environmental parameters can be easily maintained relatively stable, so the obtained data can maintain good repeatability.
According to the above ultraviolet accelerated aging after the test qualified products, when used in the real use environment, the anti-aging effect will be different, especially when the hindered amine light stabilizer is added in the case of filler, its anti-aging effect is unstable. Although the outdoor exposure test of woven bags takes a long time and has a large investment of manpower and financial resources, the test data obtained basically meet the actual use requirements, and can be used for the anti-aging quality evaluation and anti-aging effect monitoring of woven bags.
Daily in the use of woven bags, the placement of woven bags, temperature, humidity, light and other external conditions directly affect the service life of woven bags, especially in the outdoor open air placement, rain, direct sunlight, wind, insects, ants and mice, etc., will accelerate the damage of the pull quality of woven bags. Flood prevention bags, coal bags placed in the open air, etc. need to consider the UV resistance and antioxidant capacity of the woven bag itself. Ordinary woven bags for families or workers and farmers are placed indoors in a place free of direct sunlight, dry, and free of insects and ants, and sun exposure is strictly prohibited.
