The big bag includes the polyester fiber textile layer on the outer layer and the transparent plastic layer set on the inner layer. The top of the big bag is provided with a feeding port and the bottom end is provided with a detection port; after the production and processing of the polyester fiber textile layer on the outer layer is completed, It is necessary to set a transparent plastic layer on the inner layer; the inner transparent plastic layer can reduce the leakage of the inner material on the basis of the strength of the outer polyester fiber textile layer, and facilitate the transportation and loading and unloading of the material.
1. Periodic lifting test Fill the contents evenly into the container bag to full load, hang a load equivalent to twice the large load, use the bag for 70 times within a limited period, and use the bag for 30 times at a time. Repeatedly improve. Whether the container bag is qualified or not mainly depends on whether there is any abnormality in the contents and bag body, and whether the connection part is damaged. If it is not, it means that it has passed the test.
2. Vertical drop test. Use lifting equipment to lift the full-load container bag. The bottom of the bag is more than 0.8 m above the ground, and then drop it vertically on a hard and flat ground. If the contents do not overflow, the container bag If there is no damage to the bag body, it means that it has passed this test.
3. Dumping test Stack up the fully loaded container bags with a height of three layers, then buckle the top bag with a rope and pull it down, and then observe its performance. In this test, no base fabric and stitches occur in the container bag The damaged parts and other abnormal conditions mean that the container bag has passed this test.
4. Orthogonal test, make the side of the full-load container bag lie on the ground, and hang one or two lifting lugs (if there are four lifting lugs) of the container bag with a lifting device, at least 0.1m/s Lift the hoist to the upright position and make it fully off the ground. In this test, if there is no abnormality in the bag body of the container bag and the seamed part of the bag body and the sling, it means that the container bag has passed this test.
