Surface observation method
The main raw material for insulated gloves is rubber, and natural rubber has insulation and good flexibility. The use of good natural rubber is a form of protection for users.
After obtaining a pair of insulated gloves, you can inspect them from the front and back, paying special attention to carefully checking whether there are any punctures or scratches between your fingertips and fingertips, as well as whether cracks caused by aging or damage will affect the insulation performance of the insulated gloves.
If wearing a pair of insulated gloves with damaged fingertips while working, it is easy to cause unnecessary casualties in case of accidents such as electric leakage.
Inflation method
After aging, rubber materials will form small cracks that cannot be detected by the naked eye. If we rely solely on the naked eye to observe and judge, it is difficult to draw accurate conclusions. So, we can use the inflation method to judge the quality of a pair of insulated gloves.
The main method is to blow air inside the rubber gloves to fully inflate them, then pinch the outlet and carefully feel if there is any air leakage or contraction in the swollen gloves. Once any air leakage is found, refuse to use it.
Irrigation method
The third method is to pour water into the insulated gloves to see if the water will flow out of the cracks. If there are damaged areas, they cannot be applied again.
Generally speaking, insulated gloves made of imported natural rubber raw materials will perform better in terms of insulation performance, flexibility, elasticity, etc. It is worth mentioning that their wear resistance and corrosion resistance characteristics are more outstanding. Therefore, if you want to use insulated gloves with time and care, you must choose products from large brands.
