Classification of antistatic tonnage bags

Release date:2017-10-12 Author: Click:

An antistatic ton bag is used to conduct electrical conduction through the grounding of a conductive wire woven in the cloth and sling of the bag. It can effectively remove the static electricity produced in the loading and unloading, and prevent the combustion and explosion. It is mainly used for the packaging of hazardous materials in chemical and pharmaceutical industries.

Type D tonnage bags have antistatic tonnage bags or electrostatic dissipation characteristics, and no ground is needed. Now the Type D ton bag in the market is mostly made of fine half wire interwoven into woven fabric. Unlike the design of Type C tonnage bags, these semi conductors are parallel, but not cross linked. This type of ton bag may have electrostatic removal of the coating.

A large number of chemical materials are inflammable and explosive dangerous goods, the transportation conditions are very harsh, and the cost is extremely expensive. Use conductive ton bags and permanent anti-static ton bags to package dangerous chemicals and inflammable goods, so as to achieve the effect of flameproof and explosion-proof, reduce safety risks and reduce transportation costs.

Antistatic tonnage bags are usually divided into four categories according to their structure, which are widely used in Europe. In June 2003, the European Committee for Electrotechnical Standardization published CENELEC file CLC / TR50404 ofPractice for the avoidance "ElectrostaticsCode of hazards duo tostatic electricity". This is a very comprehensive standard of electrostatic operation in all fields of industry. One chapter points out in detail the standard for the safe use of static electricity for tons of bags. This standard divides the tonnage bags into four categories: Type A, Type B, Type C, Type D.

The Type A tonnage bag has no special electrostatic safety characteristics. Therefore, it is not recommended for the treatment of sensitive and flammable dust and powder. In addition, they also can not be used with the existing dust or flammable vapor. This kind of antistatic ton bag is usually woven with ordinary woven polypropylene fabric, and it is an insulator. Sometimes, according to the requirements, the Type A tonnage bag will use the inner lining bag or the surface coating treatment. The Type B tonnage bag is similar to the Type A type, and is also made from a common woven polypropylene fabric. But the breakdown voltage of the woven fabric of the Type B bag should not be higher than that of 4KV. This means that the Type B ton bag does not produce a spread type brush discharge.

The Type C antistatic ton bag is designed for a sensitive and flammable environment, including a combustible hydrocarbon solvent vapor environment. This kind of tonnage bag is made of conductive cloth or woven fabric coated with conductive / anti electric coating. In fact, the conductive cloth is woven fabric / flat conductive fiber.
