1、乳胶手套生产工艺,Production process of Latex glove,手套分类 Glove classification,按生产原料分类 Classification by raw material皮手套 Leather glove 绵羊皮、山羊皮、鹿皮、猪皮、牛皮等制作。Made of leather of sheep,goat,deer,pig or cattle.线手套 Cotton gloves也叫棉纱手套，纱线手套或针织手套。PVC手套 PE手套PVC手套是采用聚氯乙烯，通过特殊工艺制作而成。PVC gloves are made of polyvinylchlori

2、de.PE手套是采用聚乙烯,LDPE,HDPE,LLDPE吹膜压制而成。PE gloves are made of polyethylene,LDPE,HDPE,LLDPE.,手套分类 Glove classification,橡胶手套 Rubber gloves橡胶手套，是用橡胶薄片或薄膜制成的一类手套。Rubber gloves are made of rubber sheet or film.乳胶手套 Latex gloves顾名思义，就是使用天然乳胶加工而成，广泛应用于家庭、工业、农业、医疗、美容等行业，乳胶手套分为光面乳胶手套、麻面乳胶手套、条纹乳胶手套、透明乳胶手套及无粉乳胶手套。

3、按用途分为一次性乳胶手套、家用乳胶手套、工业乳胶手套和医用乳胶手套。约6%的人会对乳胶手套过敏。Latex gloves,made of natural latex,are widely used in house,industry,agriculture,healthcare,beauty industry.Latex gloves include glossy latex gloves,ballast-surfaced latex gloves,striped latex gloves,transparent latex gloves and no powder latex gloves.

4、According to the application,latex gloves could be classified as disposable latex gloves,household latex gloves,industry latex gloves,and surgical latex gloves.Approximately 6%of the people are allergic to latex gloves.,手套分类 Glove classification,丁腈手套主要成分是乳胶，但不会引起过敏。弹性好、防酸、抗碱、耐磨损、耐油、不带静电。应用在石油化工、电子等行

5、业，经灭菌可应用于医疗。丁腈手套不仅保持了乳胶手套良好的弹性，同时还兼备了PE和PVC手套的高强度和抗氧化能力。所以还广泛应用于食品行业。Nitrile gloves are mainly made of latex and nitrile.They do not cause allergies.And they have good elasticity,anti-acid,anti-alkali,wear resistance,oil resistance,no static.Nitrile gloves are applied in petrochemical,electronic ind

6、ustries.Also they could be used in medical industry after sterilization.For high strength and good oxidation resistance like PE gloves and PVC gloves,Nitrile gloves are widely applied in food industry.,从橡胶到乳胶 From rubber to latex,原料测试-天然乳胶Material test Natural Latex,Appearance 外观pH 酸碱度TSC(Total Soli

13、，尽可能方便使用。Easy to use,with good dexterity手套的成分Component包装，存放，保养，清洁Packing,storing,maintenance,cleaning使用说明，包装上应注明使用须知，产品的性能以及厂家可以提供的尺码等。Instruction,properties,and available size should be marked on the packaging,EN420 尺码对照表Size Table,EN388:防机械风险的标准 protect against mechanical hazards,该标准使用于所有手套的抗物理和机械

14、力损害，如磨损、切割、撕裂和穿刺等。This standard applies to gloves that protect against physical and mechanical hazards.It specifies requirements for resistance of abrasion,cutting,tear,and perforation.四个基本测试性能：耐磨：持续速度下磨坏样品所需来回的次数防割：以连续的一个速度切断样品所需要的来回次数抗撕裂：使样品开裂需要的力的大小耐穿刺：用标准的锥子穿透样品需要的力性能评级标准见下页。,EN 388 手套性能评级标准 Per

15、formance level,ASTM D3578,蛋白质（Protein）含量不超过100g/dm2残留粉(Remaining powder)含量不超过100g/dm2平均粉(Average powder)含量不超过100g/dm2抗原性蛋白质(Antigenic protein)含量不超过10g/dm2在非强制性要求方面，根据物理性能的不同，将手套分为两类，其中一类手套的物理性能要求为：老化(Aging)前的拉伸强度（Tensile strength）应不小于18MPa，扯断伸长率（Elongation at break）为不小于700；在伸长率为500%时，拉伸强度应不大于5.5MPa，老化后拉伸强度应不小于14MPa，扯断伸长率应不小于500%。二类手套的物理性能要求为老化前后的拉伸强度都不小于14MPa，老化前的扯断伸长率不小于650%，老化后扯断伸长率不小于500%，另外，老化前在伸长率为500%时的拉伸强度不大于2.8MPa。,The end,Thank you,
