为什么一次性丁腈手套在食品加工领域越来越流行？

                    WHY DISPOSABLE NITRILE GLOVES ARE GAINING POPULARITY WITH FOOD PROCESSORS

      PVC手套的经常使用的主要存在历史原因和价格导向：你的客户经常使用它或者你的供应商总是向你推荐它。Often the use of vinyl gloves is historical and price driven - your customer has always used them or their supplier always recommended them.

      然而，PVC手套和丁腈手套在成本方面的差距是微乎其微。下面是非常的重要信息，值得你传递给你的客户和企业社会责任部。

Now, however, there is very little difference in the cost between vinyl and nitrile gloves. The information below is important information to know, pass onto your customer and any active CSR department.

     关于PVC手套方面：

     VINYL GLOVE FACTS:

      一次性乙烯基手套即PVC手套。PVC生产的时候会产生大量有毒化学物质，诸如二恶英和氯乙烯。Vinyl disposable gloves are PVC gloves. PVC is known to create large volumes of toxic chemicals when manufactured, like dioxin and vinyl chlorides.

     40-50%的PVC手套是含有塑化剂，这样能使PVC手套更加柔软易初穿戴。40-50% of a vinyl glove is made up of plasticizers that make the PVC soft enough to wear.

     PVC手套中最常见的增塑剂是邻苯二甲酸盐，这种物质的毒性目前正受到密切关注。The most common plasticizer used in PVC gloves is phthalates DEHP this substance is currently under much scrutiny for its toxicity. 

     PVC手套的生产中大量使用的增塑剂是DINP,这种物种被加州列入65种化学致癌物之一。DINP (Diisononyl phthalate) is a phthalate plasticizer used in the manufacture of many vinyl gloves, was added to the Prop 65 list of chemicals as a chemical known to the state of California to cause cancer.

     制造PVC手套使用双酚(BPA)和苯甲噻唑啉酮，会引起过敏反应和皮炎。The use of Bisphenol (BPA) and Benzisothiazolinone in the manufacture of vinyl gloves is known to cause allergic reactions and dermatitis with prolonged use.

     这些化合物大都易溶于油，不受手套材质分子的束缚，所以很容易迁移到食物上。

     These compounds are mostly soluble in fat and are not bound to the glove molecule - so migrate onto the food quite easily.

     与丁腈和乳胶手套不同的是，PVC手套材质的分子没有交连，导致手套膜上有更多的空隙，细菌和病毒渗透到食物中。Unlike nitrile and latex gloves the vinyl glove molecules are not cross-linked leading to more holes in the glove film and high levels of bacteria and virus permeation onto food.

     PVC手套处理也是一个长久的问题。PVC需要很长时间才能分解(几十年)，如果燃烧大量有毒气体就会产生。PVC手套的原材料石油是不可再生的。Disposing of vinyl gloves is also an ongoing problem. The PVC takes a very long time to break down (many decades), and if incinerated large amounts of toxic emissions are generated.All the materials to make PVC gloves are non-renewables namely oil.
