一次性手套的耐化学性

当使用某些磨料的化学物质，你需要了解特殊的手套材料所提供的（耐）化学保护。另外，暴露（在化学物质里的）时间长度、条件和化学浓度会影响到手套的性能。

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. 

 

退化和耐久性

Consider degradation and breakthrough time

手套是以它们承受暴露在某些化学物质的程度而估价的。虽然没有标准的测试，但强度通常是通过材料暴露在化学测试中测试后进行评估的。当手套退化了，它可能会膨胀、变硬、变色。通常，退化取决于手套的材料对于特殊应用而言是否合适。

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. 

 

除了退化，如果化学物质导致了乳胶、丁腈、聚乙烯的退化，手套必须经过渗水和耐久性试验。耐久性（试验）是从最初接触化学物质到在手套内侧检测到化学的一段时间长度，这能表明工作人员能受到手套多久的安全防护。渗水（试验）是一种化学物质通过在分子水平上的，而不是通过手套细孔、针孔或其他可见开口的材料(试验)方式。

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' pores, pinholes or other visible openings. 

 

 

 

丁腈手套有着极强的耐化学性。可耐普通的化学材料及许多特殊的化学材料，如水处理化学品或工业清洗化合物。

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

 

了解手套使用的环境

Understanding the conditions of glove use

 

暴露的时间长度和化学物质的浓度能决定任何类型手套的耐化学性。打算使用（前），对任何手套作现场测试是很关键的。这样工作人员就能知道怎么保护自己了。特别是当（工作）设备需要使用化学混合物。手套通常能被测试（到能）抵抗一种化学物质，但它们可能不能抵抗（某些）特异性混合物。

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.

 

例如，爱马斯AMMEXGloveworks橡胶手套能为食品服务业、医疗、牙科、清洁和工业应用提供防护屏障。橡胶能耐各种化学物质，提供安全保护，但橡胶手套不能长时间接触某些化学物质，如乙酸乙酯、脱漆剂和橡胶溶剂。尤其相对其他材料而言，橡胶更能耐丙酮，这使得它适用于美甲沙龙（行业）。

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.

 

丁腈手套可能更适合于汽车行业，因为它们对许多在这一行业中的化学物质都有更好的抵抗性，如汽油和制动液。但是，对于任何手套的选择而言，考虑（其）针对工作中接触到的特异性化学物质的抵抗性是很关键的。

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.
