Conductive container bag is an essential and important package for many industries in the process of cargo transportation, especially for the chemical industry! Because the products produced in the chemical industry are basically inflammable and explosive dangerous goods, which have a very high demand for transportation. Improper packaging may lead to the safety of these dangerous goods during transportation Therefore, at this time, the use of conductive container bags for its packaging can effectively play the role of flame-proof and explosion-proof, reduce potential safety problems, and also save a lot of transportation costs for enterprises!
Most of the existing container bags use synthetic fiber (such as polypropylene or polyethylene fiber) as the base cloth of the container bag. The container bag made of this base cloth has suitable firmness, flexibility and price. But the big disadvantage is that this kind of fabric can produce static charge when it is rubbed. In the process of loading and unloading, the inevitable friction will produce sparks on the surface of the bag, which will cause the objects in the bag to fire or explode. Therefore, the use safety of the bag is not guaranteed.
Now that we know how the charge on the container bag is generated, we can take corresponding measures to eliminate the static electricity: the general conductive container bag is to add conductive wire to the container bag, the shape and other parameters of the container bag are the same as those of the ordinary container bag, only the difference is that the container bag body, sling, loading and unloading port, loading and unloading port and There are conductive wires at the lock edge, which are in contact with the conductive film. The distance between the conductive wires of the bag body is less than 5cm, and the suture of the bag body can also be attached with leakage proof suture, and the inner surface of the bag body can also be provided with leakage proof layer; the shape of the bag body can be a cuboid, a cube, a cylinder, a pyramid or a cone; the loading and unloading port can be one or two; The outer edge of the sewing part of the bag body can have a lock edge. In this way, the conductive container bag can achieve the following functions: the function before improvement
1、 There are conductive wires at the loading and unloading ports and suspenders of the bag body. The suture of the bag body and suspenders forms a conductive network with the bag body. Because the distance between the conducting wires of the bag body is less than 5cm, the surface resistance of the bag body can be less than 10 ohm, so as to achieve the function of anti-static and dredging static electricity and improve the use safety of the container bag.
2、 The inner surface of the bag body can also be provided with a leakproof layer, so as to block the pores between the suture and the fabric of the bag body, which is more suitable for packing and storing powdery materials without leakage. In order to avoid the generation of electrostatic sparks, people usually weave conductive fibers into woven fabrics in a crisscross and crisscross way, and then use this fabric to sew the container bag. However, in the process of using the container bag, the grounding electrode must be reliably connected with the ground, so that the static electricity can be released in time through the conductive fiber, so it is very inconvenient to use, and when the container bag is not connected with the ground If the earth is connected normally, it will easily cause electrostatic sparks and combustion events from the surface.
In order to overcome the shortcomings of the existing technology, a new type of conductive container bag, low electrostatic container bag, has emerged. The FIBC comprises a bag body composed of plastic or other woven fabrics, the upper end of the bag body is provided with a feeding tube, the bag body and the woven fabric of the feeding tube are woven into the conductive fiber in a unidirectional parallel interval, and the size of the conductive fiber is 30-150 dtex; As an improvement of the conductive container bag, the lower end of the low electrostatic container bag body is provided with a discharge pipe and a lifting lug is arranged on the bag body;
In addition, a further improvement is made to the conductive container bag: the good size of the conductive fiber is 22-56 dtex, the conductive fiber is evenly distributed with equal spacing, the spacing between the conductive fibers is 1 / 2-5 / 6 inch, and the good spacing is 2 / 3 inch. Through the above two improvements, the improved function is as follows: the conductive fiber is woven into the woven fabric of the container bag body and the feeding tube in a unidirectional and parallel space, which makes the container bag generate corona discharge to the atmosphere without grounding, effectively eliminate the static electricity on the surface of the container bag, and avoid the reliable connection between the grounding electrode and the ground of the previous products The trouble of timely release of static electricity through conductive fiber; the low-static container bag can also be provided with discharge pipe and lifting lug as required; in addition, the conductive fiber of the low-static container bag has the conductive reliability, which makes the container bag have the characteristics of reliability, low static electricity and safety, so it can be widely used in explosive and dangerous occasions. At the seam of the bag body, the suture line of the leakproof rope can be added, and the inner surface of the bag body can also have a leakproof layer (PE inner bag), which can also achieve the purpose of leakproof. It can also be used for loading powder and thick materials.
The above is the principle of electrostatic charge generation on the conductive container bag. Now you should all understand it. There is no electrostatic charge on the ordinary container bag, so it can not play any role when packaging some goods prone to electrostatic charge. But the conductive container bag is not the same. It can effectively block the static electricity of the goods when it is used to pack the goods that are easy to static electricity. It is very safe and reliable!
