As we all know, butadiene is a kind of rubber, made from acrylonitrile and butadiene. It can be widely used in different industries, such as electronics, chemical industry, aquaculture, food, hospital, scientific research and other industries, household work, factory protection and other occasions. So how should enterprises choose powdered vinyl gloves vendor wholesale?
Oil resistance and solvent resistance options
The selection of powdered vinyl gloves vendor generally focuses on its oil and solvent resistance, so the effect of oil and solvent resistance is often the focus of selection. The oil resistance of powdered vinyl gloves vendor depends on the content of acrylic. The higher the content of acrylic, the stronger the oil resistance. When the acrylonitrile content is 35%-40%, it shows superior oil resistance.
Powder free surface option
There are a number of powdered vinyl gloves vendors on the market, but many of them label their packaging as "powder free." It is found that many powdered vinyl gloves vendors claim that they are powder free, but they still have powder on the surface, which seriously affects the quality of the products.
Applicable clean room grade differentiation
gloves suitable for 100-level purification workshop are latex and butyl fine, powdered vinyl gloves vendor is widely used. At present, there is no clear international standard for glove classification. Generally, the main difference lies in whether the number of dust particles is large or small. Gloves with a large number of dust particles are of low grade. Take one sample of gloves of two different grades, cut them into pieces of 1-2cm square, put them into a clean beaker, add about 100ml of the same amount of pure water (tap water can also be used if there is no condition), stir them with a glass rod, shake them for 1-2 hours if there is a condition, and visually detect the polar paper with more impurities in the pure water. Relatively few impurities indicate high grade. This method can be distinguished between class10 and class, but it cannot be distinguished between class10 and class. Professional detection methods are needed.
Test powdered vinyl gloves vendor for quality
Because powdered vinyl gloves vendor is in direct contact with the product most of the time in use, so the quality requirements are quite strict. The IEST standard requires that the powdered vinyl gloves vendor which has been cleaned without dust before use should be tested. For powdered vinyl gloves vendor used in production, relevant tests should also be carried out before use after recycling cleaning, and they can only be used after passing the test. The test consists of four parts: appearance test, physical test, ESD performance test and chemical test.
