一次性手套的后期处理方式-中英文对照

Finishing the glove:How does it work?

你可知制造手套的最后一步？

After gloves are manufactured,they need to be finished to facilitate donning and doffing.The material of gloves often makes it difficult for users to don without some type of finishing technique.Now there are several different ways to go about finishing a glove,including polymer coating,chlorination and polyurethane finishes.

手套的制作过程大致包括清洗手模、乳胶浸渍、卷边及脱卸。但由于本身材质的原因，仅仅完成这四部还不能使得手套便于穿戴。现在就有着很多方法去解决这个问题，包括施粉、氯化、高分子涂层和聚氨酯饰面。

Powdering

施粉

Powdered gloves,as the name implies,use a powder coating to help users don and doff disposable gloves by absorbing excess moisture on the hands.Powdering takes place following manufacturing.In the past,gloves had powdered formers,making powder a byproduct of manufacturing.Due to advancements in manufacturing technology,gloves are powdered with

food-grade cornstarch,before they are taken from their formers and turned inside out.Powdered gloves are not suitable in situations where the powder could interfere with biological and chemical processes,such as chemical sealing or wound closure.Powder also damages paints and varnishes by leaving a residue behind.For this reason,manufacturers have adopted alternative ways to finish gloves.

施了粉的手套称之为有粉手套。顾名思义，就是在手套上用粉末涂层吸收手上多余的水分，来使穿戴者自如穿脱。施粉这一工艺是伴随着制造过程而发生的。以前大部分的手模为有粉手模，所以生产出来的手套本身就带有粉末。这些粉末包含原先的滑石粉到技术改良后的玉米淀粉。但有粉手套并不适用于一些生物和化学处理过程。因为粉末可能会干扰到这些生产过程：如化学密封或伤口闭合（粉末可能会致使其留下残留））。粉末也会破坏色漆和清漆。为此，生产商采取了一些替代的方法。

Chlorination

氯化

Chlorination is a finishing method for powder free gloves.Manufacturers wash gloves in a chlorine gas or a solution of hypochlorite and hydrochloric acid.Gloves are then rinsed to prevent the chemical from interacting with the glove further.The solution reduces the surface tackiness of the glove and also gives it a softer texture.When used on latex,the chlorination process also reduces the amount of latex proteins,to make them less likely to cause an allergy.One thing to keep in mind is that chlorination slightly reduces the shelf life of products because the chemicals break down the glove material.This method was developed for latex gloves,but new advancements in technology have made the process available for nitrile gloves.The AMMEX Gloveworks Heavy Duty Orange Nitrile Glove is an example of a chlorinated glove.

氯化属于手套的无粉处理方式。它分为单次氯洗和双次氯洗。氯洗液分为氯气溶液或次氯酸盐溶液。这种氯洗工艺减少了粉末在手套的粘着量，也使手套的质地相对更为柔软。对于乳胶手套而言，氯气能减少乳胶中的乳胶蛋白，使它们不会致敏。但是，氯化缩短了产品的保质期，因为化学物质分解了手套材料。这种工艺虽是为乳胶手套开发的，却也可用于丁腈手套。AmmexGloveworks重型橙色丁腈手套就是氯化手套的范例。

Polymer coating

高分子涂层

The majority of disposable gloves on the market are now powder free. Applying a polymer coating is a more recent method:Manufacturers use polymers,such as silicones,acrylics and hydrogels,to make gloves easier to don.The polymer coating has less surface friction than the glove material, which makes it slip on the hand more easily.The polymer is generally applied while the glove is still on the former.Polymer coating is most frequently used on nitrile and latex.For example,AMMEX GlovePlus Black Nitrile Gloves are polymer coated.

高分子涂层的发明使得一次性无粉手套能够大量应用于市场。它开拓了一个全新的工艺：工人使用聚合物，如硅树脂，丙烯酸树脂和凝胶，使手套更易穿戴。这是因为该聚合物涂层的表面摩擦比手套材料小，这样它在手上就更易滑动。这种工艺一般应用在手套从手模脱卸下来之前，最常用于丁腈和乳胶手套。例如，Ammex Gloveplus黑色丁腈手套就应用了高分子涂层。
