PE保护膜为什么会出现白点现象1：关于PE保护膜出现白点，我们要知道在

Why white spots appear <br>on PE protective film 1: With regard to white spots on PE protective film, we must know that in different batches of inks, we should increase the particle size detection index and implement strict control on the basis of it. It should be particularly pointed out here that the particle size of its full-bottom ink variety, and that the particle size distribution is outside the standard range, we must not use it; furthermore, it is very necessary for us to choose an excellent and stable supplier of. <br> <br>2: For white spots on PE protective film, we need to use its special adhesive. Here, we need to pay attention that the surface tension of the composite special adhesive is very low. Furthermore, our coating and spreading effect on the surface of the glue layer is much higher than that of the general-purpose adhesive. <br> <br>This also means that if we use glue glue, it will be easy to control the leveling of the glue liquid, so that a more ideal coating state can be achieved. In this way, from the adhesive coating state, we can avoid white spots on the PE protective film by using electronic glue. <br> <br>3: With regard to the white spots on the PE protective film, there is one more thing we may need to pay attention to, that is, there is a certain matching relationship between the viscosity of the glue and the number of wire rollers. In layman's terms, even if the matching range is too large, the coating state of the glue will be destroyed. In this case, the phenomenon of white spots of the PE protective film will appear.

PE保护膜为什么会出现白点现象<br>1：关于PE保护膜出现白点，我们要知道在不同的批次的油墨要增加粒度检测指标，在其基础上实施严格的控制。这里要特别指出的就是其满底油墨品种粒度，还有就是粒度分布在标准范围外的，我们对其一定不可以采用；再者，我们要选择一个优良的稳定的供应商也是十分的有必要的。<br> <br> 2：关于PE保护膜出现白点，我们要用其专用粘合剂。这里的话，我们需注意，关于其复合专用粘合剂的表面张力是非常低的，再者我们在胶水层表面的涂布铺展效果要远远的高于通用型粘合剂的。<br> <br> 这也就说明我们采用胶水胶的话，就会很容易的控制胶液的流平，这样就可以达到一个较为理想的涂布状态。这样单单的从粘合剂涂布状态上来说，我们采用电子胶就可以避免PE保护膜出现白点了。<br> <br> 3：关于PE保护膜出现白点，还有一点我们可能需要注意，那就是胶液的粘度与网线辊线数其实是存在一定的匹配关系。通俗的来说的话，就是超出匹配区间太大的情况下，就会使胶的涂布状态遭到破坏，这样的话也就会出现我们所说的PE保护膜白点的现象。

Why does PE protective film appear white spot<br>1: As for the appearance of white spots in PE protective film, we need to know that in different batches of ink, we need to increase the particle size detection index, and implement strict control on the basis of it. In particular, it should be pointed out that the particle size of the full bottom ink varieties, as well as the particle size distribution outside the standard range, we must not use it; moreover, it is necessary for us to choose a good and stable supplier.<br>2: As for the white spot of PE protective film, we need to use its special adhesive. Here, we need to pay attention to the fact that the surface tension of the special composite adhesive is very low, and the spreading effect of our coating on the surface of the glue layer is far higher than that of the general adhesive.<br>This also shows that if we use glue, it will be easy to control the level of glue, so that we can achieve a more ideal coating state. In this way, from the adhesive coating state alone, we can use electronic glue to avoid white spots in PE protective film.<br>3: As for the occurrence of white spots in PE protective film, we may also need to pay attention to that there is a certain matching relationship between the viscosity of glue solution and the number of reticle roll lines. Generally speaking, if the matching range is too large, the coating state of the adhesive will be damaged. In this way, the phenomenon of white spots of PE protective film will appear.<br>
