【爱马斯全球】无粉手套的优点

With production efficiencies and personal preferences, the trend toward powder free gloves is on the rise.

因为生产效益的提高和个人喜好问题,无粉手套的(使用)趋势正在上升。

Why use powder free gloves?

Powder free gloves have a majority market share. This is because they are best for a number of applications.

无粉手套占有大部分的市场份额。这是因为它们对于许多行业应用而言是最佳之选。

Powder free gloves are preferred for the automotive industry, for example. When powdered gloves are donned, cornstarch powder particles are released into the air and introduce a potential source of contamination. For example, when automotive technicians are installing windshields, the powder weakens the seal of the glass, which may lead to leaks. In the case of painting, finishing, and sealing applications, these particles lead to fisheyes in the finish, making powder free gloves the better choice for these applications.

比如,无粉手套非常适用于汽车工业。(如果)穿上了有粉手套,玉米淀粉粒子就会散播到空气之中,成为一个潜在的污染源。比如说,汽修师在安装挡风玻璃时,粉末就会削弱玻璃的密封性,这就会导致密封不良。在漆油漆、整理和密封应用的情况下,这些粒子会形成鱼眼(即一种缩孔)。这就使得无粉手套成了这些应用的更好选择。

Another benefit of powder free gloves is they are less messy than powdered gloves. Powder leaves residue on both hands and clothing.

无粉手套的另一个优点是它们比有粉手套干净。(因为有粉手套的)粉末会残留在手上及衣物上。

Powder free gloves are great for painting.

对于漆油漆,无粉手套是不错的选择。

How are powder free gloves made?

Historically, manufacturers have used powder when creating powder free gloves. They powdered the glove formers to make the gloves easier to remove. After removing the gloves from the formers, manufacturers rinse the gloves, turn the gloves right side out and rinse the gloves again. As powder free gloves have become more popular, manufacturers have developed innovative ways to create the gloves without powdering the formers.

从生产史上来看,以前在制造有粉手套时,厂商会对其施粉。他们对手模施粉以便手套能穿脱自如。手套脱卸后,厂商会冲洗手套,将其外侧翻出,再冲洗手套。随着无粉手套越来越受欢迎,厂商们已经开发出不用施粉的革新方法来生产手套。

One way to remove residual powder from gloves is by chlorination. Chlorination is achieved using chlorine gas or a solution of hypochlorite and hydrochloric acid. This process reduces the surface tackiness of the natural rubber latex, making the gloves easier to don because they slide over hands without sticking to the skin. Furthermore, chlorination removes residual powder and lowers latex proteins in the glove. Thus, this process is more common for latex gloves.

一种从手套上去除残留的粉末的方法是氯化。氯化(工艺)应用了氯气或次氯酸盐及盐酸溶液。这一过程削弱了(手套内侧)天然橡胶表面的粘着性,(也因为其 能)使得手套能在手上滑脱而不是粘在皮肤上,能易于穿戴。此外,氯化也去除了残留的粉末并降低了手套中的乳胶蛋白。因此,这一过程在橡胶手套的应用是很普遍的。

Another way to make powder free gloves easier to don involves using a polymer coating. Manufacturers use various types of polymers, including silicones, acrylics and hydrogels. This coating is applied to the gloves' interior while the gloves are on the former. Because the polymer has less surface friction than the glove material, it facilitates easier donning. Polymer coating is most common with nitrile gloves.

另一种使无粉手套易于穿戴的方式要应用高分子涂层。厂商会使用不同类型的聚合物,包括有机硅、丙烯酸树脂和凝胶。当手套在手模上时,这一涂层被涂在手套的内侧。因为聚合物的表面摩擦比手套材料小,所以能使手套易于穿戴。高分子涂层对于丁腈无粉手套来说更为普遍。
