Proper Selection Of Protective Gloves–(2) Different Material Of Gloves

                     Different Material Of Gloves

  1. The material of gloves for mechanical injuries

(1) Metal wire—common stainless steel wire, also chrome alloy wire, mainly used to make cut-resistant gloves. This type of material has the strongest cut resistance and is easy to clean, but heavy and inconvenient to use.

(2) Kevlar, Spectra, and other synthetic yarns are also good synthetic fiber cut-resistant materials. Although the cut-resistant ability is not as good as that of metal wires, it is light in weight and comfortable to use. After improvement and treatment, some products can also achieve The highest level of cut-resistant product standards.

(3) Butyronitrile (with fabric lining) —- with anti-wear and puncture resistance, flexible and comfortable to use.

(4) Natural latex (with fabric lining) —- has excellent elasticity, especially flexible, and has certain anti-wear, tear and cut resistance. (5) PVC (with fabric lining) —- can provide some protection against abrasion and puncture. If the material is thick, it can also have a certain ability to cut, but not tear.

(6) leather —- natural material, with various tanning treatments, has unique properties. Leather can be divided into cowhide, which has the advantages of comfort, durability, breathability and wears resistance, after being treated with chrome, it is more durable and resistant to high temperature; pigskin, with large pores, has the best breathability, and can still maintain well after washing The softness does not harden; sheepskin is the most comfortable, most durable and the best wear resistance, but because it is too expensive, it is generally only used in industries that require high touch.

  1. High-temperature resistant glove material

(1) Novoloid —- a new type of high-tech synthetic fiber, non-melting, flame resistance, high-temperature resistance, high-temperature resistance up to 1100 ℃, soft and comfortable, and can resist the erosion of many chemicals, even after repeated washing will affect its high-temperature resistance.

(2) Kevlar —- It is a widely used aromatic synthetic fiber, which is not only resistant to cutting but also resistant to high-temperature damage.

(3) Aluminized material —- can resist radiant heat of higher temperature.

(4) Leather —- If it is kept dry, it has good low-temperature resistance. At the same time, its non-melting and non-combustion characteristics make it often used to make welding gloves.

(5) Cotton —- is also a natural material, which can properly protect high and low temperatures. But because of the need to meet protection requirements, gloves are thicker and less flexible.

  1. The material of gloves resistant to electrical injury.                                                                   Electrically insulated gloves must be specially designed and strictly tested to ensure safety. Electrically insulated gloves are usually made of pure natural latex. There are two types of latex: dry and wet. Insulated gloves made of wet glue have a long processing cycle and high production costs, but the product is particularly flexible and very flexible to use. In addition, due to the special characteristics of live working and the characteristics of electrical insulating gloves, when wearing such gloves, you must first wear cotton gloves (sweat-absorbent, non-slip), then wear latex gloves, and finally wear leather protection. Gloves to prevent puncture of insulating gloves by sharp objects.
  2. Chemical substances and the different properties of chemical-resistant gloves.                                                                                                                                                                                            Pay special attention to the selection of chemical-resistant gloves.

(1) Natural latex —- In general, natural latex has better protection against aqueous solutions, such as acid and alkali aqueous solutions. Its advantages are comfort, good flexibility, and flexible use.

(2) Butyronitrile —- It has good protection performance against chemical substances such as oil, lipids, petrochemical products, lubricants, and various solvents. However, swelling will occur in some solvents, which will affect its physical properties and reduce its protective function.

(3) Polyvinyl chloride-it has a protective effect on a large number of water-soluble chemical substances, such as acids and alkalis, but it cannot protect organic substances such as solvents, because many solvents will dissolve plasticizers, which will not only cause pollution, And will greatly reduce the barrier function of gloves.

(4) Neoprene-the comfort of natural rubber is almost the same. It has good protection for petrochemical products and lubricants, can resist ozone and ultraviolet rays, and also has strong anti-aging properties.

(5) Polyvinyl alcohol —— has a very good protective effect on most organic solvents, but it is easily soluble in water, its efficacy will be reduced when it encounters water, and the material is hard and inconvenient to process.

(6) Butyl synthetic rubber has a very good protective effect against organic compounds and strong acids. It is difficult to produce and process. It has almost no protective effect against oil and grease, but it has particularly good protective properties against gas.

(7) Fluorinated rubber——fluorinated polymer, the substrate is similar to Teflon (polytetrafluoroethylene), and its surface activation energy is low, so the droplets will not stay on the surface, which can prevent chemical penetration. Chlorine-containing solvents and aromatic hydrocarbons have good protective effects.

(8) Chlorosulfonated polyethylene-has protective properties for most chemical substances that can protect alkalis, oils, fuels, and many solvents, and has good high temperatures and low-temperature resistance, wear resistance, resistance bend, etc.

  1. Anti-vibration gloves                                                                                                                                                    The anti-vibration Gloves are usually made of three-layer gloves. The inner and outer layers are made of leather or soft and comfortable synthetic fibers. The middle layer is made of silicone or other polymers that can effectively absorb vibration. Precautions in the selection and use of gloves The proper choice of gloves and the correct use of gloves are directly related to the health of the hands.
