【了解一下什么是pet塑料瓶胚外涂层与内涂层】


●外涂层避免接触饮料

【如何去测量塑料瓶胚的壁厚】


一、接触式测量法。免费看片软件此种壁厚测试方法是现在应用较为广泛的壁厚测量方法。其原理是:将测量支撑杆放入瓶内,用其镖头接触测量部位,在塑料瓶瓶身外部对应部位放置容栅传感器的测量表头接触瓶身与镖头对应。读取测量表上的厚度值读数。

二、磁感应法厚度测试。此方法原理基于霍尔效应理论,测厚时,将一枚小钢珠置于测试材料的一面,并将探头置于另一面。转动瓶子,钢珠收到探头的磁力而同时移动。

三、切片法测试厚度。这是原始的一种壁厚测量方法。受制于当时技术的限制,在早期测试塑料瓶时,很多化验员将瓶子剪碎,再用螺旋测微仪和卡尺测试其厚度值。此方法造价很低,但认为误差较大,测试效率较低,是一种渐渐被淘汰的方式。
