Ton bags are a common type of packaging and packaging bags, which have a wide range of applications. We know that after a tonnage bag is used once, its compressive strength will decrease and air oxidation will occur. Why is this?
In the geographical environment, that is, under the standard of sun exposure, the compressive strength of plastic ton bags will be reduced to 25% after one week, and 40% after half a month, most of which are unsafe. Therefore, the storage and storage of large bags is very important.
The ton bag is made of polypropylene by metal drawing, hand weaving, sewing or pasting, and the loading volume is generally 200kg-3T.
Tons of bags should be stored in a cool and clean room. When transporting, they should be protected from wind and sun, not close to the pyrogen, and the storage period should not exceed 18 months. In fact, plastic ton bags will become brittle in 18 months, so the effective period of ton bags should be reduced, and it should be within 12 months.
The storage of large bags should be protected from sun exposure.
Tons of bags (ton bags) accumulate on the surface during the whole process of packaging and transportation to produce a high electrostatic induction potential difference. It is very easy to produce electrostatic induction flames, which is very easy to cause explosion safety accidents and high voltage electric shock risks. Then how should we prevent static electricity in the application produce? The first thing to understand is the cause of static electricity:
There are two key reasons: one is the internal reason, that is, the electrical conductivity of the chemical substance; the other is the external reason, that is, the friction, flipping, and collision between the chemical substances. Many product turnover materials have internal standards caused by static induction. In addition, they are also indispensable for actual operations such as transportation, stacking, and covering in warehousing and logistics. Therefore, it is inevitable that turnover materials will cause friction, turnover, and collisions. The plastic packaging products of general products are very easy to cause electrostatic induction due to mutual friction during the whole process of stacking.
The damage is specifically manifested in two levels: one is to cause an explosion safety accident. For example, when the contents of the package are flammable chemical substances, when the vapor and gas they emit are in a certain proportion, or when the solid smoke reaches a certain concentration value (ie, the explosion limit), it will happen once it encounters an electrostatic induction flame. explosion. The second is a high-voltage electric shock. If the electrostatic induction high-potential charge and discharge is caused during the whole transportation process, it will cause discomfort of high-voltage electric shock to the actual operating staff, which often occurs when the warehouse transports plastic packaging products. During the whole process of transportation and stacking, the electrostatic induction high-potential charge and discharge was caused by obvious friction, and even the actual operation staff was overwhelmed by the electrostatic induction charge and discharge.
