What is the role of protective clothing?
(1) Heat protection suits can be divided into two types: non-adjustment and adjustment.
1) Unregulated heat-resistant clothing is represented by an aluminum foil insulated garment that has good reflective properties and can reflect radiant heat and provide heat insulation. This protective suit is equipped with aluminum foil helmets, gloves and boots with metal-coated reflective lenses. The use of such protective coverall must always pay attention to keep the surface bright and clean, otherwise it will lose the effect of reflecting radiant heat. The asbestos heat-resistant suit has a small thermal conductivity and good heat insulation, but it is too heavy and it is inconvenient to operate after wearing. Although the protective effect of the white canvas protective clothing is far less than the former two, it is economical and durable, and it is widely used at present.
（2) Adjusting the heat-proof pants is a freezing suit with a number of ice packs. The freeze suit is a vest. The front and back pockets of the vest are filled with metal flat tanks. The tanks are filled with a low-temperature non-toxic salt solution. When the salt solution heats up. It can be exchanged. This flat can also be placed in a helmet and can be used when working under high temperature and strong radiation.
(3) Anti-chemical pollution clothing Anti-acid and alkali damage to the skin, often made of polypropylene, polyester or polyvinyl chloride fabrics. Chemical protective bib pants that enters the body is usually made of various polymers that are impervious to or penetrated by the protective material and coated on chemical fiber or natural fiber fabric.
