选择正确的手套(I)：汽车行业.doc

Get the right gloves for the job: Part I Automotive选择正确的手套（I）：汽车行业Workers in the automotive industry tend to be seen as hardworking technicians who are covered in oil and grease. In many cases, these substances can present a safety hazard, be hard to wash off skin or even stain light-colored interior. 在汽车行业工作的工作人员给人的感觉就是一个满身油污、辛勤劳作的技术人员。在大多情况下，这些油污物质会带来安全隐患，难以从皮肤上洗净甚至污渍会渗透到浅色的（衣物等）内里。Hydraulic fluids, such as brake fluid, for instance, are among the dangerous fluids found in cars. When the fluids are changed or simply filled, there is a chance they could spill on a technicians hands. After prolonged contact, these fluids can permeate the skin. The resulting health risks can include nerve damage, weakness in the affected areas and even paralysis. In addition, if the fluids come in contact with workers eyes, such as by rubbing their contaminated hands on their faces, eye irritation and redness can occur. 例如制动液等液压液体在汽车行业中都是属于危险液体范畴的。当这些液体在更换或者即使简单罐装的时候，都有可能会溅射到技术人员的手上。长时间接触后，这些液体会渗透到皮肤里。如此便会造成包括神经损伤、接触面受感染、甚至皮肤麻痹等健康风险。除此以外，若工作人员用已经被污染的手触碰脸部，此类液压液体还有可能因此进入技术人员的眼睛，就会有眼睛刺激和红肿出现。Many automotive mechanics are now protecting their hands by wearing gloves. This provides a barrier between their hands and the many fluids and greases they come in contact with while working on vehicles - not to mention, it can help workers avoid contact with fluids that are particularly dangerous. 许多汽车机械师通过穿戴手套来保护他们的双手。这样在工作时给他们提供了一个双手和液压油之间的屏障，更不用说这可以帮助工作人员避免接触那些危害性液体。While the benefits of wearing gloves in the automotive industry are clear, there is some debate regarding which glove material is best, especially when choosing between latex and nitrile. 在汽车行业里穿戴手套的好处是很明确的，但仍有些争论是关于哪种手套材质是最好的，尤其是在乳胶和丁腈之间。Car mechanics who work without gloves can expose themselves to dangerous chemicals, all mechanics should wear gloves. 汽车机械师不带手套工作相当于把自己暴露在危险的化学品中，所有的机械师都应该佩戴手套。The more well-known glove When it comes to thinking about protective gloves, many people probably think of latex. These gloves are puncture resistant, tear resistant and conform to the hand. Their resistance to tearing can be a benefit and a detriment in the automotive industry. Of course, when working with the rough and at times sharp surfaces that are present under the hood of a car, mechanics want a glove that will not easily tear. However, the lower puncture resistance of latex may mean the gloves can be punctured without the wearer knowing. Although a hole may be small, prolonged exposure to harmful chemicals and solvents can occur. 最为人熟知的手套:一说起防护手套，大多数人会想到乳胶。乳胶手套抗穿刺，抗撕裂，并贴合手型。它的抗穿刺性在汽车工业中既有好处也有损害。当然，在处理表面粗糙、有时表面尖锐的车辆引擎盖时，汽车机械师希望有一双不容易被撕裂的手套。然而乳胶的抗穿刺阻力较低，这就意味着乳胶手套在穿戴人员不知道的情况下就会被刺穿。尽管穿刺孔很小，但长时间接触有害化学物质和溶剂后也会有损害发生。There are both powdered and powder-free versions of latex automotive gloves. Powdered latex gloves are easier to don when hands are wet, as the powder can absorb sweat and other moisture. However, powdered latex gloves can present an issue because powder particles can escape into the air and contaminate vehicle finishes, paints, varnishes and sealants. In the automotive industry, this fact has presented issues when windshields are installed. If the powder weakens the seal around the glass, leaks can occur. 乳胶手套分有粉和无粉两种，有粉乳胶手套由于粉末可以吸收湿气和其他水分，在手湿的情况下更易穿戴。但有粉乳胶手套中的粉末粒子会进入空气污染已处理的车辆、颜料、清漆和密封剂。在汽车工业中，这类情况常在安装挡风玻璃时被遇到。如果粉尘使挡风玻璃的密闭性变差的话，就会发生泄漏。This glove material was part of the reason disposable gloves did not make much of an impact on the automotive industry right away. When some latex gloves came in contact with oil, grease and gasoline, they didnt stand up to the substances, which left many workers looking for a more durable product. 乳胶材质本身特点决定了乳胶手套未能在汽车工业广泛使用。乳胶手套在接触石油、油脂和汽油时并没有表现的很出色，这就导致更多的工作人员寻找更耐用的手套产品。A more durable, latex-free glove Nitrile is a type of synthetic polymer that does not contain latex. For this reason alone, nitrile gloves are a suitable option for many auto mechanics, as wearers do not have to worry about latex allergies, which can lead to various symptoms that can inhibit a technicians work. These include hives, itching, skin redness and rashes. 一种更耐用、不含乳胶的手套：丁腈是一种不含天然蛋白质的合成聚合物。就这一点而言，丁腈手套是许多汽车维修的合适选择，穿戴者不需担心因为乳胶过敏导致的各类症状，如荨麻疹、瘙痒、皮肤发红和皮疹，这就不会限制一个技术人员的工作状态。Nitrile is created by combining three monomers: acrylonitrile, carboxylic acid and butadiene. 丁腈由三种物质合成：丙烯腈、羟基和丁二烯These gloves do a better job of standing up to the many chemicals and solvents - particularly grease, oil and gasoline - auto mechanics come in contact with on a daily basis. This means workers can go through fewer gloves and lower their chance of exposure to hazardous fluids. The resistance is the result of the acrylonitrile. 在对抗许多化学物质和溶剂时，特别是汽车机械师每天接触的油脂、石油和汽油等，丁腈这类手套能做的更好。Nitrile gloves have excellent tear resistance, which is provided by the carboxylic acid. 丁腈手套对于羧酸，有着出色的抗撕裂能力。They are also more puncture resistant, a key benefit for auto mechanics who regularly work with sharp objects. 它们对于常和尖锐物品工作的汽车机械师来说也有着更好的抗穿刺能力。The butadiene is responsible for nitrile gloves flexibility. As such, wearers may feel their hands can move freely while wearing these gloves, which can be advantageous if they are trying to reach into a tight space. However, nitrile does not have the elasticity of latex, but will conform to the hand as the glove is warmed by body heat. 丁二烯的材质属性决定了丁腈手套所具有的灵活性。如此，穿戴者能感觉他们的双手自由无阻力，即便手需要进入狭窄地方操作也会显得便利。虽然丁腈没有像乳胶那样好的弹性，但穿戴后丁腈手套会因为体温而变得更贴合手部。Which glove is used more often? Although latex gloves have some uses in the automotive industry, many mechanics opt for nitrile gloves. The chemical r
