Nitrile butadiene rubber is prepared by lotion polymerization of butadiene (H2C=CH-CH=CH2) and acrylonitrile (H2C=CH-CN). It is mainly produced by low-temperature lotion polymerization, and has the properties of two homopolymers.
The butadiene component endows the copolymer with elasticity and cold resistance, the acrylonitrile component has strong polarity, and the - CN group can make the copolymer have good chemical corrosion resistance, especially oil resistance (referring to hydrocarbon oils)
Nitrile gloves can be divided into two types: powder and non powder.
There are two lengths of nitrile gloves: 23cm and 30cm;
The thickness is 0.08-0.09mm, and the color is mainly blue. The main finished product packaging is 100pcs per box, with specifications of XS, S, M, L, and XL.
Discuss the applicability of gloves based on the "Ansel Glove Penetration/Degradation Protection Guidelines".
Note that the "Glove Protection Guide" lists the degradation and penetration data of gloves.
The first square of each column is encoded with three different colors to represent the overall degradation and penetration level of each glove.
Green indicates that the glove is very suitable for use with the chemical;
Yellow indicates that the glove should be carefully put into use;
Red indicates that the glove is prohibited from being used together with the chemical.
Capital letters represent levels.
E: Excellent;
VG: Very good;
G: Okay;
F: Generally;
P: Poor;
NR: Not recommended for use.
Unlike latex gloves, nitrile gloves are insoluble in non-polar solvents and can effectively withstand non-polar reagents such as alkanes and cycloalkanes, such as n-pentane, n-hexane, cyclohexane, etc. These reagents are mostly marked in green. It should be noted that for aromatic hydrocarbons, the protective performance of nitrile gloves varies greatly. For example, in benzene, the degradation level P, and the overall degradation and penetration level of gloves are marked in red.
In toluene, degradation grade F, permeation time 34 minutes, permeability F, marked as yellow.
In xylene, the degradation level is G, the permeation time is 96 minutes, the permeability is F, and it is marked as green.
50% sodium hydroxide, 10% hydrochloric acid, 47% sulfuric acid (acid for batteries), 30% hydrogen peroxide, etc. are all labeled as green, with degradation level E and a penetration time of>360 minutes.
Methanol, ethanol, n-propanol, pentanol, cyclohexanol and other alcohols are also marked as green.
Nitrile gloves have poor or no protective performance against dimethylformamide, acetone, butanone, tetrahydrofuran, chloroform, dichloroethane, chlorobenzene, phenol, benzaldehyde, and ethyl acetate, and are marked in red
