[tips] Shanghai Naomi teaches everyone how to test the quality of protective gloves

Labor insurance gloves must be tested by the relevant departments before they leave the factory. When some indicators meet the established standards, they will flow into the market. In addition to quality-related testing, it also performs certain tests on its water vapor absorption rate and resistance to permeation. So, what are the detection methods for these two properties?

1. Water Vapor Absorption Rate Test: Cut a round specimen with a diameter of 85 mm from each of the 3 protective gloves. Specimens should be flat, free of sutures or material defects, and the specimens should be stored for one day at a temperature of 23 degrees Celsius and relative humidity of 50 percent.

2. Permeation resistance test: The glove is immersed in water, pressurized and inflated inside the glove, and the air leakage is determined according to whether the protective glove surface has bubbles or water droplets. If the gloves are not suitable for inflation, leak detection may be used. If water droplets appear on the surface of the glove, it means that the glove is not impermeable.

Safety gloves also need to pay attention when using:

1. Use safety gloves must be selected according to the protective function of the gloves. Can not be used indiscriminately to avoid accidents.

2. Waterproof, acid and alkali resistant, chemical resistant, and oil resistant gloves should be carefully inspected for damage and aging before use.

3. Rubber, latex, plastic and other types of protective gloves should be washed clean, dry, avoid high temperatures when stored, and sprinkle talcum powder on the products to prevent adhesion.

4. Insulating gloves should be used strictly in accordance with the instructions for use, and regular inspection of electrical insulation performance, can not be used without compliance.
