詳細描述：水轉印膜水轉印花膜水披覆

膜紙廠商印刷好膜之後，它的寬度是50cm,80cm,90cm,100cm,不過一般常用的都是在50cm,除非特別需要；然後根據客戶的要求銷售給水轉印加工廠，水轉印加工廠將根據工件的大小將每張膜紙裁剪成長60cm*寬50cm，當然如果膜的寬度是80或者是90cm，那麽就是60*80，70*80都有可能。
3.    下水
膜紙裁剪成一張一張後，由兩個人工分別執兩端將溶解于水的一面朝下放置水的表面，保持水槽中的水清潔，且基本處于中性狀態,水的溫度在25～50℃，置放的時間一般在60秒左右,然後再噴活化劑,薄膜吸水後和水形成平行的存放狀態，自由地漂浮于水面上，由于水的表面張力，油墨層也會均勻地平鋪于水面上。此時用擋水板使膜紙固定位置(見圖1).
这时候的水是存放在一个水槽里, 这个水槽我们叫它为上膜槽(第一期有参考圖片),其尺寸为1.5*0.6*0.8m, 用镀锌板焊接而成，有些用不锈钢制作,有些为了节约成本起见,用几个砖头砌成也可以凑合用.上膜槽主要完成水披覆转印膜上图文的活化和薄膜向産品表面的转移。上膜設備实际上是一个具有恒温控制功能的水箱，并且有些是全自动的上膜設備用于标准型的産品的上膜操作。它的机械手可以自如地拿放産品，大大提高了生产率，也减少了人工操作的繁琐程序。
4.噴活化劑
首先,簡單介紹下活化劑,它是幾種化學品按照不同的比例調試而成,比如說丁酮,二甲苯等, 每個工廠的活化劑的配方都會多少有點區別,  同時活化劑是一種以芳香烴爲主的有機混合溶劑，能夠迅速溶解並破壞聚乙烯醇，但不會損壞紋路，使紋路處于遊離狀態,從而達到活化的效果,在水轉印行業是個重要的角色.
在膜放置在水的表面後, 將活化劑裝在容器裏,通過氣壓使活化劑達到噴槍裏,然後經噴槍使活化劑産生霧化效果,均勻地噴灑于薄膜表面，薄膜會慢慢破壞並溶解，由于油墨的抗水性，油墨層開始呈現遊離狀態(。
　5. 工件噴底漆
噴底漆這一步要視不同的工件,有些可噴,有些不要噴,有些是噴色底,比如說做種木紋效果,如果要達到好的效果,肯定要噴底漆才能襯托出木紋的效果;另外有些特殊的工件比如金屬,尼龍,玻璃等,就要噴特殊的界面漆了.
喷底漆的設備由水濂柜来完成(第一期有参考圖片),它有机身和喷油压力装置构成，喷涂所用油漆会在极高的压力下变成细密漂浮的颗粒物质，遇到産品后形成吸附力。全自动的喷油設備不仅可以对産品进行自动化操作，还解决了对操作员工的健康损害问题。
　　尽管水转印工艺本身危害不大，但是水转印过程中的有些化学物质对人体是有一定伤害的，水转印設備的自动化程度不高，人工操作的比例还比较大，这些都是水转印設備目前面临的一些问题。这些问题会得到不断的改进。　
　6.轉印
当膜纸喷完活化剂之后,就立即把已经摆放好工件的支架沿工件的轮廓逐渐贴近水转印薄膜(呈45度角度)，纹路会在水压的作用下慢慢转移到産品表面，由于油墨层与承印材料或者特殊涂层固有的黏附作用而产生附着力。转印过程中，承印物与水披覆膜的贴合速度要保持均匀，避免薄膜皱褶而使纹路不美观。原则上讲，应保证纹路适当的拉伸，尽量避免重叠，特别是结合处，重叠过多，会给人以杂乱的感觉。越是复杂的産品对操作的要求越高。
7. 水洗
转印完之后,不要立即从水里拿出来,待在转印槽里浸泡2-3分钟之后,再放置到冲水机里冲洗,冲掉工件表面的残渣留的薄膜, 再用清水洗去没有固着在産品表面的浮层。注意水压不能太大，否则容易对转印的纹路造成破坏
8. 幹燥
除去産品表面的水分，以利于转印墨层的彻底干燥；为增加附着力，单个的样品可用吹风机干燥，批量的货将産品放在烘干箱内干燥或者烘烤线烘烤。塑料産品干燥温度不能太高，大致在50～60℃，温度太高容易使承印物变形；金属、玻璃、陶瓷等材料的干燥温度可以适当提高。
9.噴光油
③噴塗保護漆
　　洪干之后,为增强图案层对环境的抵抗性，要在表面进行喷漆处理。喷漆可以用溶剂型光油，也可用UV光油，采用紫外线固化干燥。相比之下，UV固化更适应環保要求。溶剂型的光油需与配套硬化剂混合使用，涂层的厚度可通过添加适量的稀释剂改善光油的黏度来控制
10.洪幹
注意不能在烘箱中幹燥。可以自然幹或者緩慢幹燥.針對不同的承印材料.

"A list of the things you are going to buy," Mary remarked. To regain the highroad we had turned into a northerly fork, and were in as lovely a spot as we had seen all day. Before us and close on our right were the dense woods of magnolia, water-oak, tupelo and a hundred other affluent things that towered and spread or clambered and hung. On the left lay the old field, tawny with bending sedge and teeming with the yellow rays of the sun's last hour. This field we overlooked through a fence-row of persimmon and wild plum. Among these bushes, half fallen into a rain-gully, a catalpa, of belated bloom, was loaded with blossoms and bees, and I was directing Camille's glance to it when the shots came. Another outcry or two followed, and then a weird silence. Ferry led Kendall and me into the woods, the other two remaining. We found rising ground, and had ridden but a few minutes when from its crest we looked upon a startling sight. In front of us was a stretch of specially well farmed land. Our woods swept round it on both sides, crossed a highway, and gradually closed in again so as to terminate the opening about half a mile away. Always the same crops, bottom cause of the war: from us to the road an admirable planting of cotton, and from there to the farther woods as goodly a show of thick corn. The whole acreage swept downward to that terminus, at the same time sinking inward from the two sides. On the highway shone the lighted rear window of a roadside "store," and down the two sides of the whole tract stretched the hundred tent-fires of two brigade camps of the enemy's cavalry. Their new, white canvases were pitched in long, even alleys following the borders of the wood, from which the brush had been cut away far enough for half of them to stand under the trees. The men had quieted down to sleep, but at one tent very near us a group of regimental officers sat in the light of a torch-basket, and by them were planted their colors. A quartet of capital voices were singing, and one who joined the chorus, standing by the flag, absently yet caressingly spread it at such breadth that we easily read on it the name of the command. Let me leave that out. "Quite so. The man was all twisted from his hip, and he had a crooked nose." They were all flying from the plague, which was spreading, and emptying the bazaars and workshops. The Exchange being closed, trade was at a standstill, and the poor creatures who were spared by the pestilence were in danger of dying of hunger. “But she knew them,” objected Dick. “She wouldn’t throw over the wrong ones and she couldn’t get the right ones.” “That’s what we thought.” "Well, if I had sich a name as that I wouldn't expect people to git it right. There's no sense in havin' a Dutch name that makes your tongue crack like a whip. Well, this Mr. McFillemgoody is Si's boss, and he writes a nice letter, and says Si done so well at Chickamaugy that some other boss—a Colonel or Corporal—" "It is not good to be free," he said at last, in a reasonable, weary tone. "In the cold there is a bad thing. In the rain there is a bad thing. To be free is to go to these bad things." "To London!" HoME 免费看一级a视频ENTER NUMBET 003www.xzbcw.cn
