How to identify the quality of used woven bags is a problem that many consumers have been concerned about. In order to help more consumers learn how to identify the quality of woven bags, our factory summarizes the following points for consumers' reference:
In general, high-quality woven bags are non-toxic and tasteless, and generally cause less damage to human body. Although they are made of various chemical plastics, they are more environmentally friendly and have a greater recycling power.
From the appearance of the distinction between good and bad can see how the woven fabric, whether there is silk jump, the color meets the requirements.
From a professional point of view, the material of the woven fabric is recycled material, semi-transparent material or new material. The woven bag produced by the new material has excellent quality and can be reused. The woven bag produced by the original material is about 8 in the outdoor. More than a month.
In general, woven bags produced from recycled materials are of poor quality, and woven bags produced from recycled materials are characterized by a color that is neither white nor transparent. We can also shake it again to see if there are any debris. The last point is whether the smell is strong. The recycled woven bag is made of waste plastics, industrial waste, etc. Most of the colors are turbid, and the hand feels sticky and has a strong plastic taste.
The naked eye can only be roughly identified, and it needs to be detected accurately. If it can be detected, it is generally necessary to check the appearance quality (with or without broken wire, cleanliness, stitching quality, weft density, length and width, weight, etc.), tensile load (radial and weft, seam and seam bottom) ), drop test, heat resistance, hygienic performance, etc., we can use the force to rub, if the surface wrinkles after flattening is not obvious, the quality is better, the hand is more brittle. You can also look at the thickness and density, pull a pull to see the strength, the relative pull-off force of the woven bag containing recycled material is significantly reduced.
If a secondary feed is added, the relative pull-off force is lower. The elongation at break is unstable, and the rate of breakage varies depending on the amount of added regrind. The brittleness of the recycled material woven bag is obviously increased, especially the low temperature brittleness is worse, the impact resistance is decreased, the electrical insulation is decreased, the aging degree is increased, and the speed is accelerated.
