無紡布袋凹印時呈現粘頁現象的原因

收卷后的墨膜a附于原膜的后面，發生這種現象的原因有:在印刷歷程中油M的用量過大;油墨的干燥速度太慢;收卷時的張力過大;油墨自身的a協力不足，無紡布袋定做廠家下面為您介紹凹印時呈現粘頁現象的原因：
The reason for this phenomenon is: the amount of oil m is too large in the printing process; the drying speed of the ink is too slow; the tension during winding is too large; the ink itself is insufficient, and the non-woven bag is made to order
當凹印墨中溶劑極性較強時，與水有較好的親和性，在相對濕度較高的季節，溶劑能大量吸收空氣中水分，且極性酸胺基團也有必然的親水性，隨時間推移印墨中水量增多，再加上氣溫高，聚酞胺分子降解，更易引起粘頁。
When the polarity of the solvent in gravure ink is strong, it has good affinity with water. In the season of high relative humidity, the solvent can absorb a lot of water in the air, and the polar acid amine group also has certain hydrophilicity. With the passage of time, the increase of water in gravure ink, coupled with high temperature, the degradation of poly (phthalamide) molecules, it is easier to cause page sticking.
解決的要領有:適當調解著墨量;適當提高烘箱于燥溫度(但不行過高，不然會導致墨膜的外貌層迅速干燥，而吊膜內部沒有干燥反而更容易呈現粘連現象);適當降低收卷張力;印刷半制品宜豎放不宜平放;有金屬粉的墨(如金色墨、銀色墨)因自身的a協力較弱，有時會因少許外界壓力而發生粘連，更應小b注意;控制出產情況的相對濕度在60%一65%之間。

The main solutions are: adjust the ink amount properly; increase the drying temperature of the oven properly (but not too high, otherwise the appearance layer of the ink film will dry quickly, and the adhesion phenomenon will appear more easily if the inner part of the hanging film is not dry); reduce the winding tension properly; the semi-finished products should be placed vertically rather than horizontally; the printing process should be carried out in a proper way; Metal powder ink (such as gold ink, silver ink) due to their own weak a, sometimes due to a little external pressure and adhesion, more attention should be paid to
