  • Detail

Although high temperature resistant gloves are not unfamiliar to us, we don't know much about the professional knowledge of high temperature resistant gloves. High temperature resistant gloves, also known as thermal insulation gloves, fire-proof gloves and flame-retardant gloves, are mainly used in steel, casting, photovoltaic, glass, aluminum plastic, electronics and other industries

high temperature resistant gloves are special high temperature resistant gloves used in high temperature environments. They can withstand a certain temperature, do not burn and can effectively insulate labor protection gloves. Moreover, the application of high-temperature gloves is more and more extensive, and has become an indispensable labor protection article in high-temperature working environment. High temperature gloves are also widely used in petrochemical industry, cement, ceramics, power plants, aluminum industry, welding and other high-temperature working environments. Next, the editor will introduce the materials of high-temperature gloves and precautions for the use of high-temperature gloves

high temperature resistant glove material

1. Ceramic fiber: ceramic fiber is also called aluminum silicate fiber. Because one of its main components is aluminum oxide, which is the main component of porcelain, it is called ceramic fiber. Adding zirconia or chromium oxide can further improve the service temperature of ceramic fibers. Ceramic fiber is a kind of fibrous lightweight refractory material, which has the advantages of light weight, high temperature resistance, good thermal stability, low thermal conductivity, small specific heat and mechanical vibration resistance. Therefore, it has been widely used in machinery, metallurgy, chemical industry, petroleum, ceramics, glass, electronics and other industries. Ceramic fiber products are a kind of excellent refractory materials. It has the advantages of light weight, high temperature resistance, small heat capacity, good thermal insulation performance, good high temperature thermal insulation performance, non-toxic and so on

2. Asbestos fiber: asbestos is also known as “ Asbestos ”, It refers to silicate mineral products with high tensile strength, high flexibility, chemical and thermal resistance, electrical insulation and spinnability. It is the general name of natural fibrous silicate minerals. It governs 2 categories and a total of 6 minerals (serpentine asbestos, amphibole asbestos, actinolite asbestos, amphibole asbestos, iron asbestos, tremolite asbestos, etc.). Asbestos is composed of fiber bundles, which are composed of very long and fine fibers that can be separated from each other. Asbestos has high fire resistance, electrical insulation and thermal insulation, and is an important fire prevention, insulation and thermal insulation material. However, because asbestos fiber can cause asbestosis, pleural mesothelioma and other diseases, many countries have chosen to completely ban the use of this dangerous substance

3. Glass fiber: glass fiber (formerly known as glass fiber or fiberglass in English) is mainly composed of silicon dioxide, aluminum oxide, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. according to the amount of alkali in the glass, it can be divided into alkali free glass fiber (sodium oxide 0% ~ 2%, belonging to aluminobosilicate glass) Medium alkali glass fiber (sodium oxide 8% - 12%, belonging to sodium calcium silicate glass containing boron or non boron) and high alkali glass fiber (sodium oxide more than 13%, belonging to sodium calcium silicate glass). Glass fiber is an inorganic non-metallic material with excellent performance. It has a wide variety. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but its disadvantages are brittle and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its monofilament is several microns to more than 20 meters, which is equivalent to 1/20-1/5 of a hair filament. Each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments. Glass fiber has higher temperature resistance than organic fiber, non combustible, corrosion resistance, good heat insulation and sound insulation, high tensile strength and good electrical insulation. Chemical properties of glass fiber: melting point 680 ℃, boiling point 1000 ℃, density 2.4~2.7g/cm3

4. Aramid fiber: the full name of aramid fiber is "e; Poly (p-phthaloyl p-phenylenediamine) "e;, In English, it is aramid fiber (DuPont's trade name is Kevlar), which is a new high-tech synthetic fiber. It has excellent properties such as ultra-high strength, high modulus, high temperature resistance,

5, acid and alkali resistance, light weight, etc. its strength is 5 ~ 6 times that of steel wire, its modulus is 2 ~ 3 times that of steel wire or glass fiber, its toughness is 2 times that of steel wire, and its weight is only about 1/5 of that of steel wire. It does not decompose and melt at 560 degrees. It has good insulation and aging resistance, and has a long life cycle. The discovery of aramid fiber is considered to be a very important historical process in the material industry

precautions for the use of high-temperature gloves

1. When using high-temperature gloves, you should immediately contact high-temperature objects, and feel whether the insulation layer of high-temperature gloves can effectively insulate heat through your hands; After several tests, observe whether the surface layer is burnt or damaged

2. The heat insulation performance of the inner insulation layer may be reduced after continuous use of high-temperature gloves for a long time. At this time, in order to ensure safety, the time of exposure to high temperature should be adjusted

3. High temperature resistant gloves should be placed in a clean and ventilated environment after use to prevent the gloves from being affected by moisture, which will affect the service life of gloves. Aramid high temperature resistant gloves should avoid exposure to sunlight, otherwise the color of gloves will change, but will not affect the use

4. For dirty high-temperature resistant gloves, check the instructions to see if they can be cleaned. If they cannot be cleaned, immediately replace them with new high-temperature resistant gloves. Damaged high temperature resistant gloves should be stopped immediately, otherwise it will cause injury to the operator; The dust-free and high temperature resistant gloves will reduce the dust-free effect after being damaged, so they should be replaced immediately

editor's summary: This is the introduction of the material of high temperature resistant gloves and the precautions for the use of high temperature resistant gloves. I hope it will be helpful to you. If you want to know more about it, you can pay attention to the information
