Nitrile labor protection gloves have oil-proof performance, so they are especially suitable for fields such as repair shops, oil fields, and factories. The market demand is also very large. For some large manufacturers, every time they purchase these gloves, they purchase thousands of pairs at one time. The purchasing personnel of these manufacturers all know that there are quantity discounts. However, during the purchasing process, they also need to learn how to distinguish the quality of nitrile gloves. It is believed that many purchasing personnel cannot distinguish. In order to help, next I will explain how to judge the quality of a pair of nitrile labor protection gloves. To know whether a pair of nitrile labor protection gloves is of good quality, you can first observe the appearance of the gloves. High-quality gloves are required to have four absences on the surface: no yellowing, no black spots, no stains, and no holes. Yellowing, black spots, and stains can be seen with the naked eye. Then how can we identify a hole in the glove? In fact, the method is very simple. You can take a sample pair of nitrile gloves sent by the manufacturer and inject water or inflate the gloves. Once you find that the gloves leak water or air, it means that the gloves have quality problems. Nitrile labor protection gloves produced by professional manufacturers will not leak air after being inflated, and their quality is even better than that of balloons. These gloves do not contain latex protein, so they will not cause allergic reactions. If you experience skin allergies after wearing these gloves, it also means that the gloves have serious quality problems and need to be returned as soon as possible. And high-quality nitrile gloves should also have good abrasion resistance, puncture resistance, tensile properties, and tensile strength, and they also have a very long service life. It can be said that the quality of nitrile labor protection gloves is mainly related to the manufacturer. At present, there are many manufacturers that can produce gloves on the market, but very few manufacturers truly have the ability to produce gloves of excellent quality. It is believed that many enterprise purchasing personnel have purchased inferior gloves. It is recommended not to be greedy for cheap prices and choose regular large manufacturers with reasonable prices for procurement.
