Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Its products have excellent oil resistance, high abrasion resistance and good heat resistance. It is made of high-quality nitrile rubber with other additives and refined and processed; it does not contain protein, has no allergic reaction to human skin, is non-toxic, harmless, durable, and has good adhesion.
Nitrile gloves are widely used in housework, electronics, chemicals, aquaculture, glass, food and other factory protection, hospitals, scientific research and other industries.
Introduction
Nitrile rubber is produced by emulsion polymerization of butadiene (H2C=CH-CH=CH2) and acrylonitrile (H2C=CH-CN). It is mainly produced by low-temperature emulsion polymerization and has two homopolymers. performance. The butadiene component imparts elasticity and cold resistance to the copolymer, the acrylonitrile component has strong polarity, and the -CN group can make the copolymer have good chemical resistance, especially the oil resistance (referring to alkane oil). Increasing the content of acrylonitrile in the rubber can improve the oil resistance of the rubber, but the elasticity and cold resistance will be reduced. Its products have good oil resistance, higher abrasion resistance and better heat resistance.
Nitrile gloves can be divided into two types: powder-free and powder-free. The length of nitrile gloves is 23cm and 30cm; the thickness is 0.08~0.09mm, and the color is mainly blue. The main product packaging is 100pcs per box, and the specifications are XS, S, M, L, XL.
In conjunction with "Ansell Glove Permeation/Degradation Protection Guide", discuss the suitability of gloves. Note that the "Guide to Glove Protection" lists the degradation and penetration data of gloves. The first square in each column uses three different color coding methods to indicate the overall level of degradation and penetration of each glove. Green means that the glove is very suitable for use with the chemical; yellow means that the glove should be used carefully in the application; red means that it is forbidden to use the glove with the chemical. Capital letters represent grades. E: excellent; VG: very good; G: good; F: fair; P: poor; NR: not recommended.
Different from latex gloves, nitrile gloves are insoluble in non-polar solvents, (it can effectively withstand alkane, cycloalkane non-polar reagents, such as n-pentane, n-hexane, cyclohexane and other reagents are mostly marked as green It should be noted that for aromatic hydrocarbons, the protective performance of nitrile gloves is quite different. For example, in benzene, degradation grade P, the overall grade of degradation and penetration of gloves is marked as red. In toluene, degradation grade F, penetration time 34 minutes, the permeability F, the label is yellow. In xylene, the degradation grade G, the permeation time 96 minutes, the permeability F, the label is green. 50% sodium hydroxide, 10% hydrochloric acid, 47% sulfuric acid (battery Use acid), 30% hydrogen peroxide, etc. are all marked as green, degradation grade E, penetration time>360 minutes. Alcohols such as methanol, ethanol, n-propanol, pentanol, cyclohexanol, etc. are also marked as green. Butyronitrile Gloves have poor protection against dimethylformamide, acetone, methyl ethyl ketone, tetrahydrofuran, chloroform, dichloroethane, chlorobenzene, phenol, benzaldehyde, and ethyl acetate, and are marked in red.
Nitrile gloves are a type of protective gloves commonly used in laboratories.
Features
1. Use high-quality nitrile rubber with other additives, refined and processed
2. No protein, no allergic reaction to human skin
3. Non-toxic and harmless
4. Strong and durable, good adhesion
Application
Housework, electronics, chemical, aquaculture, glass, food and other factory protection, hospitals, scientific research and other industries.
In order to prevent the gloves from slipping and improve the comfort of use, the palms of the cut-resistant gloves are dipped. According to the different dipping gels, they are divided into three types: latex, nitrile and polyurethane. Among them, polyurethane gloves have thinner colloids and are generally used in gardening and electronics industries with relatively high sensitivity requirements; latex gloves and nitrile gloves have relatively thick colloids, latex gloves have better anti-slip properties, and nitrile gloves have better oil stain resistance. Suitable for mechanical processing, logistics handling, oil depot operations, etc.
