Plastic container bags usually use PP and PE as raw materials, their resistance value is large, and the product is poor in water absorption, so plastic container bags are prone to static electricity. When the working environment (place) or the materials contained in the material have items with low ignition energy, it is extremely Electrostatic ignition and explosion accidents are prone to occur. In order to avoid accidents, anti-static plastic container bags were first developed abroad. The research and development of conductive container bags at home and abroad, as well as the relevant standards and experiments of conductive container bags, were analyzed. Before 2002, abroad A systematic study of the static electricity of plastic container bags was carried out, the corresponding method of manufacturing anti-static plastic container bags was proposed, and the classification of anti-static plastic container bags was promulgated, as well as the corresponding test standards. Chinese enterprises are in 2003 Begin to develop anti-static conductive plastic container bags in accordance with foreign standards. At present, there are already many companies in China that can produce conductive plastic container bags, namely C-type plastic container bags, but they have not successfully developed D with their own intellectual property rights. Type bag.rn The European CLC organization issued a standard in 2003: PD CLC/TR 50404:2003 (June 2003). As early as May 2002, the IEC issued a standard: IEC 61340-4-4, which was further improved after this standard Modified and released a new standard in 2005: IEC61340-4-40:2005.PD CLC/TR 50404:2003 (June 2003) standard divides plastic container bags into A, B, C, and D types, according to the plastic collection The electrostatic physical parameters of bagging are judged and divided into A, B, C-type bags, and the D-type bag should use combustible gas to contact the plastic container bag to judge whether it is qualified. rn IEC 61340-4-4:2005 standard: suitable for processing , All big bags intended to be used in flammable and explosive environments where the minimum ignition energy exceeds 0.14mmJ and the charging current is less than 3.0wA.
Conductive container bags are also called anti-static container bags, which can be divided into conductive container bags and low static container bags. It conducts electricity through the grounding of the conductive wire woven in the bag body fabric and the sling. It can effectively remove the static electricity generated during loading and unloading to prevent dangerous situations such as combustion and explosion. It is mainly used for packaging dangerous goods in the chemical, pharmaceutical and other industries. Regardless of the kind of conductive container bag, its ultimate goal is the same: to eliminate the charge generated by friction on the container bag.
Uses of conductive container bags:
Many chemical raw materials are flammable and explosive dangerous goods, the transportation conditions are very harsh, and the cost is extremely expensive. Use conductive container bags and permanent anti-static container woven bags to pack chemical dangerous, explosive and flammable materials, so as to achieve the effect of flame-proof and explosion-proof, reduce potential safety hazards, and reduce transportation costs.
