This protective clothing with reflective metal film coated lenses foil helmet, gloves and boots. The use of such protective clothing must always keep the surface clean and bright, or they will lose the reflected radiant heat performance. Asbestos heat protective clothing thermal conductivity, good heat insulation, but too heavy, inconvenient to wear after the operation.
