Hand is both a direct tool of labor production, but also the first tool of labor production, a molding, not renewable, strain repair difficult, therefore, choose the right gloves for safety protection is essential.
For laboratory gloves only to be the first layer of security protection, but should pay attention to maintenance. Laboratory, the common role of gloves are divided into: non-slip (Ma), insulation,Nitrile Coated Gloves anti-mechanical damage, conservation (no powder) and anti-chemical corrosion.
Laboratory gloves, primary protection focus on insulation, anti-mechanical damage, the use of weaving gloves; professional protection focus on chemical corrosion; maintenance level,Nitrile Coated Gloves with gloves and will not dry skin, irritation, allergies, and even delay the healing of hand wounds The
Primary protective gloves: woven gloves with knitted fabrics, leather or synthetic materials; anti-cutting gloves with Kevlar materials, Dyneema materials and steel materials; thick leather, special synthetic coating Layer, insulation cloth, glass wool heat gloves.
Protection range: for anti-wear, piercing, cutting, insulation, for high temperature environment, such as operation.
Professional protection: chemical substances and irritating to the skin of the agent in the opening and use of easy to hurt the opponent, according to the characteristics of chemical substances, professional protection.
Natural rubber (latex): natural latex from the tropical rubber tree, latex milky white, high elasticity is not easy to deformation,Nitrile Coated Gloves durable pull is not easy to break; natural rubber is a polyisoprene as the main component of the natural polymer compounds, In the tire industry.
Can be effective for alkaline, alcohol, and a variety of chemical dilution of water solution to provide effective protection, and can better prevent aldehyde and ketone corrosion, but the use of gloves, poor handling.
Polyvinyl chloride (PVC): from vinyl chloride monomer by polymerization reaction to form a polyvinyl chloride resin, prepared by processing.
Anti-chemical corrosion ability, almost all of the chemical dangerous goods, with antistatic properties, can be applied to a clean environment. Use temperature range: -4 ℃ ~ 66 ℃; high temperature 80 ~ 85 ℃, began to soften, high temperature decomposition of vinyl chloride (VCM) toxic.
Polyethylene (PE) gloves: polyethylene monomer from the polymerization reaction to form polyethylene resin, made by processing. Differences with polyvinyl chloride (PVC): Polyethylene plastic bags are non-toxic and can contain food; PVC (PVC) plastic bags are toxic and can not be exposed to food.
Disposable gloves, can not be high temperature, with water, anti-oil, anti-bacterial, acid and other functions; gloves operating price, but poor ventilation, sweat and so easy to volatilize.
Nitrile rubber gloves: nitrile rubber is made of butadiene and acrylonitrile by emulsion polymerization. Material excellent oil resistance, high wear resistance, heat resistance is better, strong adhesion. However, the low temperature resistance is poor, the ozone resistance is poor,Nitrile Coated Gloves the insulation performance is poor, and the elasticity is slightly lower.
Gloves can prevent grease (including animal fat), xylene, polyethylene and aliphatic solvents and most pesticide formulations, with a certain anti-static properties, low surface chemical residues, suitable for use in dust-free environment. Due to poor flexibility, the use of basic gloves are also a one-time.
Chloroprene rubber gloves: from chloroprene (ie 2 - chloro - 1,3 - butadiene) as the main raw material for α - polymerization and production of synthetic rubber, with oil, heat, fire, sun - resistant, ozone - resistant , Acid and alkali, chemical resistance.
Gloves for a wide range of comfort and natural rubber similar to the petrochemical products, lubricants have a very good protective effect, but poor cold resistance, should not be used at low temperature, the product is not suitable for long-term storage.
Butyl rubber (IIR) gloves: from isobutylene and a small amount of isoprene synthesis, chemical stability and thermal stability, the most prominent is the air tightness and watertight, long material as car inner tube.
In addition to the characteristics of the material, only as a medium-sized glove gloves of the material, common in the glove box, anaerobic box, incubator, operation box operation,Nitrile Coated Gloves the use of fenic acid, aqua regia, nitric acid, strong acid, alkali, toluene, alcohol Superior durability.
Polyvinyl alcohol (PVA) gloves: polyvinyl alcohol, organic compounds, white flakes, flocculent or powdered solid, tasteless. Soluble in water (> 95 ℃).
It provides a high level of protection and corrosion resistance for a wide range of organic chemicals such as aliphatic, aromatic, chlorinated solvents, fluorocarbons and most ketones (except acetone), esters and ethers.
