How Do I Choose the Best Chemical-Resistant Gloves?

High temperature resistant gloves are special high temperature resistant gloves used under high temperature environment. Different high temperature resistant gloves can be selected according to the contact temperature of the hand. Extremely high temperature mixed chemical fiber five-finger gloves are designed with wear-resistant leather for the palm and index finger.

High temperature gloves

Can work continuously under high temperature. It can work intermittently under different high temperature.

High temperature resistant gloves use:

High temperature resistant gloves can be divided into: carbon fiber high temperature resistant gloves asbestos high temperature resistant glass

High temperature resistant gloves are used in many industrial links, the most common of which is the protection of the operator's hands under high temperature environments. We divide the high temperature into 3 cases: 1, high ambient temperature; 2, radiation high temperature; high temperature.

1. High ambient temperature: This is the temperature equivalent to the weather forecast. It is difficult to protect with protective equipment in daily life and industrial operations. ) Generally use air conditioning to cool down. It is basically not involved in hand protection.

2. Radiation high temperature: This is equivalent to the temperature in the summer heat. It is the high temperature caused by heat radiation such as the sun or fire. The widely used protection method today is to reflect heat, such as the use of aluminum foil to reflect Partly radiated heat.

3. Exposure to high temperature: This is the high temperature that we generally refer to. Many casting components, metal parts and other objects in the industrial field have their own temperature. In industrial operations, people need to move or touch this high-temperature part. At this time, protection from high temperature is required.

A lot of myths about buying insulated, high-temperature gloves (protection against contact temperature):

Is it possible to equip with suitable gloves as long as the temperature of contact with the object is provided? Why should I consider contact time when choosing high temperature gloves? How long can heat-resistant gloves be in contact?

Two factors that must be taken into consideration when choosing high temperature resistant gloves are: contact temperature + single contact time. These two factors are indispensable. The temperature of the contact object is to consider that the glove material on the contact surface of the glove with the high temperature object will not be physically or chemically reflected due to high temperature, such as burning after burning or carbon, or oxidation after high temperature. The single contact time is to consider the time when the temperature from the outer surface of the glove reaches the inner layer of the glove and exceeds the temperature that human hands can tolerate. If you have less than this time in a single contact, then it is within a safe time range.

Therefore, when selecting suitable high-temperature gloves, two points that must be considered are: 1. Does the temperature of our actual object exceed the gloves temperature we announced, and the single contact time does not exceed the heat conduction time of the glove at the actual object temperature?

In the above two necessary conditions, we also need to consider related factors:

The weight of the object to be carried is generally heavier. Because the force of squeezing the glove is greater, the shorter the heat conduction time of the glove, the shorter the time for a single contact with the hot object. The frequency of contact with the object, the shorter the idle time between a single contact, the shorter the heat conduction time. If the frequency is too high, it is recommended to increase the heat dissipation time or use gloves. The hand shape and thickness of the gloves are relatively thick. Because under the same conditions, the thicker the gloves, the longer the heat transfer distance, and the longer the contact time, but the heavier the gloves. When protection requirements are met, the smarter the better. The mechanical properties of gloves, high temperature resistant gloves are mostly contact with metal castings, which require relatively good mechanical properties, which generally include abrasion resistance, cut resistance, and resistance to cracks. These properties are also directly related to the service life of the insulated gloves and direct economic utility. Other properties of gloves, such as the special environment of use, such as many electronics industries, need to use high-temperature gloves in dust-free workshops, then it is required that high-temperature resistant gloves do not lint and antistatic. For example, when contacting high-temperature objects with liquid, it is required that the outer surface of the insulated gloves can be waterproof or even resistant to acid and alkali.

How long is the contact time of high temperature gloves?

The contact time of high-temperature resistant gloves starts from contact with high temperature and ends up being felt hot by people's hands, not when they feel a little hot. This time is at least 15 seconds in the CEen407 standard.
