SY教你如何分别拉伸膜的质量

       Now, the logistics industry is a new industry, so the tensile membrane has been widely used, stretch film is a piece or pallet packaging and other packaging, to stretch film has good transparency in use, when we are in the test, you can take a transparent plastic light transmittance and fog methods of test. So can you tell the quality of the tensile film?
  如今,物流行业是最新型的一种行业,因此拉伸膜也得到了广泛的应用,拉伸膜是将单件或托盘包装和其他捆扎包装,拉伸膜在使用中需要具有很好的透明度,当我们在进行检验的时候,就可以采取透明塑料透光率和雾度试验方法。那么拉伸膜的质量你能分辩出来吗?
Stretch film
One: PVC plastic film and plastic film on the silicon stretching from the peeling test, the opposite side of the hard mask coating glue to glue and glue kneading, tightly bonded together, and then pulled away from that between gum and gum is the longest stretch of rubber wire can not be more than 0.2 mm, so the possibility of stretch film when using the minimal degumming.

  一:将拉伸膜的PVC塑料面膜与涂塑上硅的离型试剥离,将面膜反面涂布胶水的一面用劲捏合,使胶与胶严密地粘合一同,然后再拉离,注意胶与胶之间被抻的胶丝最长不能超过0.2毫米,这样,该拉伸膜在使用时脱胶的可能性就极小。

 
 
Two: check the thickness of PVC mask is also very important. Because it is related to maintaining the impact force of the membrane, usually the thickness of the drawing film is about 9mic. If the demand is deep, the thickness of the mask should be added correspondingly, otherwise it will be breakdown and damage the processed object.

  二:查验PVC面膜的厚度也很重要,由于它关系到维护膜接受的冲击力,通常该拉伸膜的厚度以9mic左右为宜,若是需求深雕,面膜的厚度就应相应添加,不然会被击穿,损坏被加工的物体。

 
 
Three: detection of tensile membrane available micrometer, only by visual, touch is not easy to grasp, because the diameter of hair silk is 7 or so, just touch sensitivity is difficult to reach, who weighed each volume weight, actually maintaining membrane base paper and glue thickness is not the same, so it is difficult to accurately sure, detection of 9mic mask thickness due to the opposite is also coated with a layer of glue, so should reach 11 silk as the standard, rather than the total amount of 9mic stretch film and glue.
  三:检测拉伸膜可用千分尺,单凭目测、手摸不易精确把握,由于一根头发的直径为7丝左右,试想手感灵敏度是难以到达的,有人用秤称每卷的分量,其实维护膜的底纸和胶水厚薄不一样,所以也难以精确把握,检测9mic面膜的厚度因其反面还涂布一层胶水,所以应到达11丝为准,而不是拉伸膜加胶水的总量9mic。
 
In the production process of the tensile membrane, we must pay attention to the control of each process, and it can also improve the efficiency of industrial production.

 在拉伸膜的生产过程中一定要注意每一道工艺的控制,从而也可以很好的提高工业生产效率!
