Cold-proof helmets are also known as cotton helmets and dual-purpose helmets. Cold-proof helmets are protective equipment to prevent impact objects from hurting the head. It is composed of leather or leather cap, inner shell, insulation layer and inner lining. There is a certain space between the cap shell and the cap liner, which can buffer and disperse the instantaneous impact force, thereby avoiding or reducing direct damage to the head. In extremely cold environments, it can be used for construction and wear, which can block the wind, prevent cold, keep warm, resist corrosion, not easy to age, and has good shock resistance and penetration resistance.
Cold protection helmet structure classification:
1. External FRP, ABS cold-proof helmet: It is composed of leather cap, inner shell, thermal insulation layer and inner lining. The shell is made of glass fiber reinforced plastic, and the outer layer is composed of leather or leather cap, wool red velvet or sheep shearing.
2. Built-in FRP, ABS cold-proof helmet: It is composed of leather or leather cap, inner shell, thermal insulation layer and inner lining. The inner shell is made of glass fiber reinforced plastic, and there are six equally spaced holes at the bottom of the inner shell.
Material classification of cold protection helmet:
(1) Plush red velvet material cold protection helmet
(2) Sheep shearing material cold protection helmet
The above are some classification and basic characteristics of cold-proof helmets. In winter, the weather is cold and dry, and a cold-proof helmet is necessary.
