四大差别对比项普通胶带硅凝胶胶带过敏易过敏低致敏痛感

撕除痛感强烈

无痛撕除不沾毛发持粘性不能反复粘贴可以反复粘贴便利性需用剪刀裁剪可以手撕硅凝胶胶带的作用机理1为什么低致敏、不易导致红肿瘙痒?机理
硅Si  是地壳中含量仅次于氧的元素具有极佳的生物相容性无毒无刺激、无致癌致畸性不溶于水和无机酸除强碱、强酸外不与任何物质发生反应
因其稳定、安全性广泛应用于食品、医药、电子等行业如硅(矽)胶奶瓶、奶嘴、乳房填充等
为什么无痛撕除、不粘毛发?机理
因为剥离强度小。剥离强度是衡量胶带性能的一个基本参数。它表明,你需要用多大的力,才能把胶带撕下来。普通胶带剥离强度通常不小于1.0N/CM而硅凝胶胶带剥离强度通常不小于0.14N/CM,也就是说,硅凝胶胶带的剥离强度是普通胶带的1/7左右。剥离强度=粘性? NO!粘性=剥离强度 x 接触面积细腻光滑的皮肤,在显微镜下是凹凸不平的

VS
对比分析:普通胶带的胶面只能覆盖到皮肤凸起的部分,而硅凝胶胶带可以接触到皮肤的凹槽下,增加接触面积,从而增加粘性。3为什么可以反复粘贴?机理
1. 硅凝胶拒水(不溶于水、不吸收水份)普通胶带在撕下时,会粘连皮肤上的汗液和污垢,从而导致粘性很快下降;而硅凝胶胶带在撕下时,不会粘连汗液,所以可以保持长时间的粘性不变。2. 硅凝胶的可塑性强轻轻粘上时,粘性不一定很好。但用力压迫时,胶带与皮肤的接触面积加大,粘性就足够了。
         刚出生的宝宝,皮肤娇嫩细腻、吹弹可破,耄耋之年的老人,皮肤褶皱不平、饱含岁月沧桑。开颜理解每一位年轻的宝爸宝妈,对宝宝的悉心呵护,也了解为人子女的你,对父母照料的无微不至。愿您和家人的每一天,都与健康、笑脸相伴!
