When working with certain abrasive chemicals, you need to understand the chemical protection that particular glove materials offer. In addition, length of exposure, conditions and chemical concentration impact the performance of the glove. 

工作中,接触某些具有腐蚀性化学物质时,你需要了解不同材料手套的防化学性能。此外,接触时间、条件、化学物质浓度对手套性能也有影响。

Consider degradation and breakthrough time  

手套的老化和耐腐蚀性能


Gloves are rated on how well they withstand exposure to a certain chemical. Though there is not a standardized test, strength is typically scored by exposing the material to a test chemical. As a glove degrades, it may swell, wrinkle, get stiff or change color. In general, degradation determines whether a glove material is a good fit for a specific application. 

手套性能的评估会基于它们对化学物质的耐受性来衡量。尽管没有一个标准化的测试,但可以通过手套和被测试化学物质的接触来评定手套的耐用性。当手套老化时,它可能会膨胀、起皱、变硬或变色。大体上讲,老化现象决定了一种手套是否适合具体的应用场合。


In addition to degradation, gloves must be tested for permeation and breakthrough time if a chemical causes specific degradation to latex, nitrile or vinyl. Breakthrough time is the length of time between the initial contact with a chemical and when residue is detected on the inner side of the glove, which indicates how long workers are able to safely where the glove for barrier protection. Permeation is the way a chemical passes through a material on a molecular level without entering through the gloves pinholes or other visible openings. 

如果某种化学物质造成了乳胶、丁腈或PVC手套的显著老化,那么除了老化值,还要测试手套的对化学物质的防渗透性和被穿透时间。穿透时间是指,从手套开始接触化学品开始到手套内侧渗出化学物质的这段时间。这样工作人员有了使用手套做安全防护的时间参考。渗透性是指某种化学物质通过非针孔或其他可见开口,而是通过分子间隙穿透手套。


Rile gloves have superior chemical resistance against common chemicals as well as many specialty chemicals, such as water treatment chemicals or industrial cleaning compounds.

丁腈手套拥有优良的抗化学性能,可抵抗常见化学物质以及许多特殊用途的化学品,如水处理化学品和工业清洗剂。

Understanding the conditions of glove use 

手套使用场景


With any type of glove, the length of exposure and concentration of the chemical may determine how resistant it is. For any intended use, it's crucial to do on-site testing with any gloves so workers know how to protect themselves, especially if the facility uses chemical mixtures. Gloves are often tested for resistance to one chemical, but they may not be rated against specific mixtures

任何类型的手套,接触时间和化学物质的浓度,能决定手套的耐久性能。打算使用前,进行现场测试很关键,这样工人就知道如何保护自己了,尤其是在需要配合使用化学混合物的机械设备时。通常使用一种化学物质进行手套测试,但是对于某些具体的化合物,可能不适用。

 

For instance, AMMEX Gloveworks Latex Gloves offer barrier protection for food service, health care, dentistry, janitorial and industrial applications. Latex gloves offer secure protection against a variety of chemicals, but latex breaks down over time with continued exposure to certain chemicals, such as ethyl acetate, paint remover and rubber solvent. Latex is resistant to acetone, which may make these gloves a good fit for nail salons, especially compared to other materials.

例如,爱马斯Gloveworks系列乳胶手套为食品服务,医疗、牙科、清洁和工业提供基本的保护。对于很多化学用品,乳胶手套能提供优秀的保护,但是不能长时间接触某些化学物质,如乙酸乙酯、脱漆剂、橡胶溶剂。相对于其他物质,乳胶手套更加耐丙酮,这使得这种手套更加适合美甲行业。

 

Nitrile gloves may be better suited for automotive applications because they are more resistant to many of the chemicals used in this type of work such as gasoline and brake fluid. However, for any glove choice, it's crucial to consider the resistance to specific chemicals that are used on the job. 

丁腈手套更加适合汽修行业,因为对于这种工作所使用的许多化学用品,如汽油和制动液,它都具备更好的抵抗性。然而,对于手套的选择,考虑(手套)对工作中所使用的具体化学物质的抵抗能力是很关键的。
