The composition and protection principle of high temperature resistant gloves should be solved first. High temperature resistant gloves are generally composed of a high temperature resistant layer, a heat insulation layer and an inner comfort layer.
1. High temperature resistant layer
The high-temperature resistant layer is the first line of defense against direct contact with high-temperature or high-temperature objects. The high-temperature resistant layer must have properties that will not undergo physical changes in a specific high-temperature environment, such as combustion and carbonization. The high temperature resistant layer also has flame retardant properties. Therefore, the high temperature resistant layer is an important part of the high temperature resistant gloves, and the performance of the high temperature resistant layer determines the maximum temperature that the high temperature resistant gloves can withstand. That is the temperature of the high temperature gloves we usually say, such as 500 degrees high temperature gloves, the highest temperature he can withstand is 500 degrees.
2. Insulation layer
The heat insulation layer is the second line of defense for high temperature resistant gloves. Under the high temperature resistant layer, when heat is conducted from the surface high temperature resistant layer to the inside, the heat insulation layer must be able to effectively block the heat transfer, thereby increasing the high temperature resistant gloves Time of contact with hot objects. The heat insulation layer becomes the heat insulation layer again, and the heat insulation layer determines the time for the high temperature resistant glove to contact the high temperature object at a time.
3. Comfortable layer
The inner layer of heat-resistant gloves is generally a flame-retardant comfortable layer, which mainly plays the role of absorbing sweat and ventilating, thereby increasing the comfort of heat-resistant gloves and enabling users to engage in various tasks more comfortably.
Check whether the high temperature resistant gloves meet the requirements
1. First determine the environment in which high temperature resistant gloves are used and the temperature of high temperature objects to be contacted. For example, in an environment with high temperature radiation, it is necessary to choose aluminum foil heat-resistant gloves that can reflect heat radiation, and dust-free high-temperature gloves should be selected for clean rooms. Carefully check the specifications and models of high temperature resistant gloves and whether the temperature resistance range of high temperature resistant gloves meets your needs.
2. Before use, carefully check whether the surface layer of the high temperature resistant glove is intact, and check whether the inner thermal insulation layer is misplaced or thinned. When using heat-resistant gloves, you should first touch the high-temperature object immediately, and feel with your hands whether the heat-resistant layer of the heat-resistant gloves can effectively insulate the heat; after repeated tests, observe whether the surface layer is burned or damaged.
After the high temperature resistant gloves are used for a long time, the thermal insulation performance of the inner thermal insulation layer may be reduced. At this time, in order to ensure safety, the time of exposure to high temperature should be adjusted.
Maintenance of high temperature resistant gloves after use
After use, high-temperature gloves should be placed in a clean and ventilated environment to prevent the gloves from being damp and affect the service life of the gloves. Aramid high-temperature gloves should avoid exposure to sunlight, otherwise the color of the gloves will change, but it will not affect the use. For dirty high-temperature gloves, you should check the instructions for use and see if they can be cleaned. If they are not, they should be replaced with new high-temperature gloves. Damaged high-temperature gloves should be stopped immediately, otherwise it will cause injury to the operator; damage to dust-free high-temperature gloves will reduce the dust-free effect and should be replaced immediately.
