不干胶标签怎么测定它的粘性?

来源:http://www.njhxsfs.com/ 日期:2019-03-06 发布人:admin 不干胶标签在运用之前,测试胶粘剂的类型是很重要的,看看这种胶粘剂是归于不干胶热溶胶仍是涂胶水纸。
Before the label is used, it is important to test the type of adhesives. It is important to see whether the adhesives are attributed to the thermosol or to the coated paper.
有些胶粘剂会与特定物质发作化学反应。例如,用作标牌的不干胶标签在特定条件下会污染某些特殊的织物。有些需求短暂粘性的标签在曝光条件下会发生耐久的粘性。而另一方面,某些需求有耐久粘性的标签在某些外表却会失掉粘性。
Some adhesives react chemically with specific substances. For example, non-drying glue labels used as labels can contaminate certain special fabrics under certain conditions. Some labels requiring transient stickiness will have durable stickiness under exposure conditions. On the other hand, some labels with durable stickiness will lose stickiness in some appearances.
常常有客户咨询说不干胶标签粘性不牢固,这原因是复杂的,有些不明就里的客户,会认为标签的质量有问题,事实上不干胶资料均是来自闻名厂商的资料。
Customers often consult that the stickiness of sticky labels is not strong. This is because of the complexity. Some unknown customers will think that the quality of the labels is not good. In fact, the sticky labels are from well-known manufacturers.
不存在质量问题,但有或许客户没有讲清粘性要求,或没有在大批量贴前,做试贴试验,有或许导致粘性没有到达抱负要求。依据多年在不干胶标签行业的经验,给出如下3种测试不干胶标签粘性的方法:
There is no quality problem, but maybe the customer did not clarify the sticky requirements, or did not do the test before mass pasting, or may lead to sticky did not meet the ambitious requirements. Based on years of experience in the label industry, the following three methods for testing the stickiness of sticky labels are presented:
1,初粘力:常见的是滚球法,即在一个斜面大将背胶面朝上固定,然后让规范的钢球(有分巨细)从上面滑下,能粘到的钢球越大,说明初粘力越大。
1. Initial viscous force: The common method is rolling ball method, that is to say, the back rubber surface is fixed upward on an inclined surface, and then the standard steel ball (with different sizes) slides down from the top. The bigger the steel ball can be adhered to, the greater the initial viscous force.
2,持粘力:即用不干胶将两块有挂钩的规范钢板粘好,然后一个钢板挂在固定架上,另一头放2kg的砝码,看下面的钢板多久后仍不掉下来,以能继续的时间计算。
2. Holding force: that is to say, two standard steel plates with hooks are bonded with dry glue, then one plate is hung on the fixing rack, and the other end is weighted by 2kg. See how long the steel plate below still does not fall down, so as to calculate the time it can continue.
3,剥离力:将不干胶黏在规范钢板上,用仪器已恒定的速度将标签撕下来,几下仪器所运用的力,此力即为不干胶的剥离力。
3. Peeling force: The peeling force is the peeling force of the non-drying glue on the standard steel plate. The label is torn off with the constant speed of the instrument. Several times the force applied by the instrument is the peeling force of the non-drying glue.
