technical innovation of insulating gloves made of natural rubber (dry rubber)

The classification standards of human body protection parts in China include head protection articles, suction protection articles, eye and face protection articles, hearing protection articles, hand protection articles, foot protection articles, clothing protection articles, fall protection articles, etc

among them, it has the function of protecting hands and arms, and the gloves for operators to wear are called hand protection articles, which are usually called labor protection gloves. Hand protection articles are classified according to protection functions, such as mechanical protection gloves (anti cutting, anti puncture, wear resistance, anti tearing), waterproof gloves, cold gloves, chemical gloves, anti-static gloves, high temperature gloves, X-ray gloves, oil gloves, insulating gloves, etc. Each type of gloves can be further subdivided according to the material. According to the materials used, insulating gloves can be divided into latex type and dry rubber type. Dry rubber type can be divided into flat type and hand type dry rubber gloves according to different production processes

[latex gloves]:

advantages: soft, good adhesion (should be impregnated hand model, convenient), bright color, high recognition

disadvantages: poor temperature resistance, below 5 ℃, poor handle, not easy to use. When the temperature is above 100 ℃, the mechanical strength decreases rapidly and the security is insufficient; Because of the poor water immersion, the latex protein is easy to hydrolyze and the insulation is decreased. 1t is reported that 7% to 11% of the users are allergic to protein. 1n order to solve the above problems, halogenation process needs to be introduced. Halogenation process will produce a large number of industrial wastes, which has a great impact on the environment

[flat type dry rubber gloves]:

advantages: water resistance, no protein rejection, wide temperature resistance, no halogenation in production process, good environmental protection and sustainable development

disadvantages: high requirements for mold, equipment precision, mold precision, early only before and after the piece error of 0.2mm. 1n the early stage, only straight type products were produced, and the qualified rate of hand type products was low (it was difficult to fill the mold with rubber, high requirements for labor, and serious bubble and air void phenomenon). The straight type gloves have poor hand feeling, inflexible wearing and use, and poor fitting. The color is not good, and the requirement for the gum is high

[hand type dry rubber gloves]:

the current process solves the above problems, innovatively adopts one-step injection molding technology to produce hand type dry rubber insulated gloves for live working

advantages: the size of hand is divided into 8, 9, 10 and 11, which is easy to wear and flexible to operate. 1t can be used at – 20 ℃ – 100 ℃. There was no protein exclusion allergy. Bright color, high recognition. Different product colors represent different degrees of protection. Without halogenation process, the environment is well protected and no industrial wastes are discharged. One time injection molding, less product defects. The technical requirements for workers are low and the qualified rate is high

the new hand type dry rubber insulated gloves lead the fashion and comfortable new trend of insulating products and live working products in China
