Advantages: It has a good protective effect on petrochemical products, anti-slip agents, acids, alkalis, hydrocarbons, alcohols, phenols, etc., so it is widely used in chemical and petrochemical industries.
Disadvantages: The cold resistance is relatively poor, so it is not suitable for use in low temperature operating environments.
the
7. Butyl rubber
Advantages: It not only protects acetone, acetonitrile, dimethylformamide, dimethyl sulfoxide and other substances, but also has excellent resistance to acids and oxidation-reduction solutions other than strong oxidizing concentrated acids, so it is more suitable for use For the disposal of toxic substances in the laboratory.
Disadvantages: poor protection against non-polar solvents.
the
8. Cloth
Advantages: It can prevent medium and low mechanical wear, and the thickened cloth gloves can be used to prevent heat and cold, so it is more suitable for operations such as heating utensils in the laboratory.
Disadvantages: It can only be used for general protection, and must not be used for chemical protection.
the
9. Leather
Advantages: It has a certain protective effect on cold, heat, spark splash, abrasion, cutting, and puncture, and has good anti-mechanical wear performance. If it is a thick leather glove, it can prevent heat. If it is coated with aluminum on the outer layer, it can prevent High temperature and heat radiation. Therefore, it is often used in liquid nitrogen operations, welding operations and other occasions.
Disadvantages: It can only be used for general protection, and must not be used for chemical protection.
