【Recommendation】Technical Innovation of Producing Insulating Gloves with Natural Rubber (Dry Rubber)

Classification criteria for the classification of human body protection include head protection products, smearing protection products, eye and face protection products, hearing protection products, hand protection products, foot protection products, clothing protection products, and fall protection products.

Among them, there is a function of protecting the hand and the arm, and the glove worn by the operator when he/she works is called a hand-protective article, and is usually called as a protective glove for labor. Hand protection products classified according to protective functions, such as mechanical protective gloves (cutting, puncture, abrasion, tear-proof), waterproof gloves, cold gloves, chemical gloves, anti-static gloves, high temperature gloves, anti-X-ray gloves , Oil-proof gloves, insulating gloves, etc. Each type of glove can be further subdivided according to the material. Insulating gloves can be divided into latex type and dry type, depending on the materials used, and the dry type can be divided into flat type dry rubber gloves and hand type dry rubber gloves according to different production processes.

【Latex Gloves】:

Advantages: Soft, good applicability (should be convenient for dipping hand-type hand molds), high visibility of bright colors.

Disadvantages: poor temperature resistance, below 5 °C, feel badly worse, bad use of work. Above 100°C, the mechanical strength drops rapidly and the safety guarantee is insufficient. The water soaking is not good, the latex protein is easy to be hydrolyzed, and the insulation property is lowered. And easy to use the protein allergy symptoms, it is reported that 7% to 11% of personnel susceptible to allergies. In order to solve the above problems, it is necessary to introduce a halogenation process. The halogenation process will produce a large amount of excretion of industrial wastes, which will have a great impact on the environment.

【Tablet Dry Gloves】:

Advantages: Anti-water immersion, no protein repulsion, wide temperature resistance, no halogenation of the production process for sustainable development of environmental protection.

Disadvantages: high requirements on the mold, the accuracy of the equipment precision mold demand, early and can only make the front and rear piece error 0.2mm. In the early days, only bar-type products were produced, and hand-type products had low qualification rates (difficult to fill molds with rubber compound, high requirements for labor, and serious phenomena of bubbles and gas). Straight-type gloves have poor hand feeling, inflexible wear and poor suitability. Bad color, high demand for the original glue.

【Hand Dryer Gloves】:

The current process solves the above problems and innovatively uses an injection molding technique to produce insulating gloves for manual dry tape electrical work.

Advantages: Hand size is divided into 8, 9, 10, 11, wear clothing, good flexibility, flexible operation. It inherits the wide temperature resistance of dry rubber gloves and can be used under -20°C to 100°C. No protein row an allergy. Bright colors and high recognition. Different product colors represent different levels of protection. Halogenated process is not good for environmental protection, and no industrial waste is discharged. One injection molding, less product defects. Workers have low technical requirements and high qualification rates.

New hand-type dry rubber insulating gloves, leading the Chinese insulation products, live working products fashion, comfortable new trend.
