A: Principles and materials of high temperature resistant gloves
High temperature protective gloves are used to protect hands during high temperature operations. It has properties such as heat insulation, high temperature resistance, and flame retardancy. The gloves are made from a combination of flame retardant outer layer, waterproof layer, thermal insulation layer and lining. Waterproof layer: made of fabrics with waterproof and breathable functions; insulation layer: made of fabrics with heat insulation, flame retardant, heat radiation protection and other properties; comfort layer: comfortable fabrics with flame retardant properties.
High temperature resistant gloves can be divided according to materials: carbon fiber high temperature resistant gloves, asbestos high temperature resistant gloves, glass and fiber high temperature resistant gloves. Aramid high temperature resistant gloves. According to performance, they can be divided into: ordinary high temperature resistant gloves, flame retardant and high temperature resistant gloves, dust-free high temperature resistant gloves, anti-static high temperature resistant gloves, dust-free, anti-static and high temperature resistant gloves, anti-cutting, wear-resistant and high temperature resistant gloves.
B: The use environment of high temperature resistant gloves
1. Metallurgy, casting, and furnace workers
The working environment of workers in metallurgy, casting, and furnaces has very strong heat radiation, generally around 800-1000 degrees. But there is no need for direct contact with high-temperature objects. Therefore, this industry generally uses aluminum foil high-temperature resistant gloves that can effectively reflect heat radiation. Aluminum foil high temperature resistant gloves can effectively reflect 95% of heat radiation. At the same time, it can withstand 800-degree high-temperature liquid splash instantly. The surface layer of high temperature resistant gloves will not be damaged or burned through. The inner layer can effectively prevent heat penetration in a short time. Give the user time to disengage. Thus effectively protecting users.
2. Electronics and chemical industry
The electronics and chemical industries generally require high-temperature-resistant gloves with good anti-static functions. Otherwise, static electricity can easily damage the product or even cause fire and explosion. Therefore, anti-static and high-temperature resistant gloves should be used. Commonly used anti-static and high-temperature resistant gloves are generally made of aramid. The surface layer is composed of 99% aramid fiber and 1% conductive yarn. It has excellent wear resistance, high temperature resistance and anti-static properties.
3. Dust-free workshops and laboratories
Dust-free workshops and laboratories have higher requirements on the cleanliness and flexibility of gloves. Therefore, dust-free and high-temperature resistant gloves are generally used. The surface layer of dust-free and high-temperature resistant gloves is made of coated or aramid filament fibers. The surface does not generate dust and does not shed chips. It can withstand high temperatures up to 180 degrees and 300 degrees and has high flexibility.
4. Photovoltaic industry
The photovoltaic industry has high requirements on the wear resistance and sustainable working performance of high-temperature gloves. The contact temperature is generally around 500-650 degrees. Generally, 500-degree aramid high-temperature resistant gloves or 650-degree aramid blended high-temperature resistant gloves are used. Aramid high temperature resistant gloves have outstanding wear resistance and high temperature resistance. Thickening the insulation layer and adding a wear-resistant layer to the surface can greatly increase the continuous use time and service life. Aramid high temperature resistant gloves are the most commonly used high temperature resistant gloves in the photovoltaic industry.
5. Glass industry
The glass industry has lower requirements for the high temperature resistance of high temperature resistant gloves. High temperature-resistant gloves have higher requirements for cut resistance and flexibility. Generally, 300-500 degree aramid high temperature resistant gloves are used. Aramid high temperature resistant gloves have good high temperature resistance and cut resistance. The surface layer is soft and the inner layer is comfortable and flexible.
