Function of medical gloves and waterproof test device
Medical gloves are disposable gloves used in medical examinations and procedures to help prevent cross contamination between nurses and patients. Medical gloves are made of different polymers, including latex, nitrile rubber, polyvinyl chloride and neoprene; They don't use flour or corn starch powder to lubricate gloves, making them easier to wear on their hands. Corn starch replaces the sugar coated powder and talc powder that stimulate the tissue, but even if corn starch enters the tissue, it can hinder healing (such as during surgery). Therefore, powder free gloves are more often used in surgery and other sensitive procedures. Special manufacturing process is adopted to make up for the shortage of powder.
There are two main types of medical gloves: Inspection gloves and surgical gloves. Surgical gloves have more accurate dimensions, higher accuracy and sensitivity, and reach higher standards. Examination gloves can be sterile or non sterile, while surgical gloves are usually sterile.
In addition to medicine, medical gloves are also widely used in chemical and biochemical laboratories. Medical gloves provide some basic protection against corrosion and surface contamination. However, they are easily penetrated by solvents and various hazardous chemicals. Therefore, when the task involves immersing the hands of gloves in solvents, do not use them for dishwashing or other means.
Whether it is a famous brand factory or an ordinary small factory, gloves need to be sampled for quality inspection after they are formed through complex production processes. The test of waterproof performance exists in the standards of industrial gloves and medical gloves. Why must waterproof performance be carried out? Is it important?
First of all, we need to understand that the waterproof performance of gloves is closely related to its protective performance. Because no matter whether industrial gloves need to resist the threat of harmful liquids and other chemicals in the working environment, or medical gloves need to be able to isolate microorganisms, such as viruses and bacteria, gloves need to be intact.
Moreover, both industry standards and national standards, without exception, have made requirements for the waterproof performance test of gloves, and also formulated detailed test methods, including test process, devices used, etc. The gloves tested also include nitrile gloves, latex gloves and PVC gloves.
Generally speaking, the factory will also test the waterproof performance, so as to control the quality of gloves and make the products meet relevant standards. Because qualified gloves can smoothly enter the market circulation and create product value.
