              閥口袋廠家如何檢測復合袋?
              發布于:2022/03/29 閥口袋廠家如何檢測復合袋?
              How do valve pocket manufacturers detect composite bags?
              外觀視覺檢查包含對復合袋平整度、清晰度的檢查等項目。主要用于檢測復合袋外表有無明顯的擦傷和針孔,封口處是否污染等。
              Visual appearance inspection includes the inspection of flatness and clarity of composite bags. It is mainly used to detect whether there are obvious scratches and pinholes on the surface of the composite bag, and whether the sealing part is polluted.
              (1)將復合袋放置手中,對準40W日光燈悄悄晃動,經過復合袋外表的反射光,即可清楚地發現復合袋外表是否有劃傷或痕跡,業界常常稱為“袋面拉絲”。如果拉絲嚴峻則應依據實際狀況,找到毛病地點,將影響降至低點,保證產品質量。我們經過調查發現的拉絲現象多半是由制袋機牽引導輥不潔凈形成的,因而一定要保證導輥潔凈。此外,導輥不滾動相同會使復合袋發生拉絲毛病。導輥不滾動的原因多由軸承缺油形成,因而保持良好的光滑是軸承滾動的根本條件。
              (1) Place the composite bag in your hand, aim at the 40W fluorescent lamp and shake it quietly. After the reflected light on the surface of the composite bag, you can clearly find whether there are scratches or traces on the surface of the composite bag. It is often called "bag surface wire drawing" in the industry. If the wire drawing is severe, find the fault location according to the actual situation, reduce the impact to a low point and ensure the product quality. After investigation, we found that most of the wire drawing phenomenon is formed by the unclean traction guide roller of the bag making machine, so we must ensure that the guide roller is clean. In addition, the different rolling of the guide roller will cause the wire drawing problem of the composite bag. The reason why the guide roller does not roll is mostly caused by the lack of oil in the bearing, so maintaining good smoothness is the fundamental condition for bearing rolling.
              (2)復合袋平整度的檢查。具體方法是:抽取數張制品袋樣張進行“空對地”投落,讓其自然著地(著地點要潔凈),調查復合袋著地后的狀況。如果復合袋著地時發作曲折,向外翹或向內拱,則闡明復合袋的平整度差,反之則闡明平整度保持良好。形成平整度差的原因一般有以下幾點:制袋溫度偏高,已破壞復合袋內層的應力挺度;結構組成不合理;資料自身厚薄不平等。留意,當PET/PE和BOPP/PET/PE結構的復合資料總厚度不超過80μm時,易發作平整度變差的現象。
              (2) Inspection of flatness of composite bag. The specific method is: take several sample sheets of product bags for "air to ground" dropping, let them land naturally (the landing place should be clean), and investigate the condition of composite bags after landing. If the composite bag is tortuous, warped outward or arched inward when landing, it indicates that the flatness of the composite bag is poor, otherwise, it indicates that the flatness remains good. The reasons for poor flatness are generally as follows: the bag making temperature is too high, which has damaged the stress stiffness of the inner layer of the composite bag; Unreasonable structural composition; The thickness of data itself is unequal. Note that when the total thickness of composite materials of PET / PE and BOPP / PET / PE structures does not exceed 80 μ M, the phenomenon of poor flatness is easy to occur.
              (3)外觀視覺檢查還包含清晰度的檢查。有些產品因為大面積無圖畫,清晰度顯得尤為重要。清晰度的檢測方法是:抽取一張制品袋,透過室內直接光源調查,如果空白處有“麻點”、“環狀物”、“霧狀”等現象,則闡明清晰度差,反之標明清晰度保持良好。
              (3) Visual appearance inspection also includes clarity inspection. In some products, clarity is particularly important because there are no pictures in a large area. The detection method of sharpness is: take a piece of product bag and investigate through the indoor direct light source. If there are "pits", "rings", "fog" and other phenomena in the blank, clarify that the sharpness is poor, otherwise indicate that the sharpness remains good.
              形成清晰度差的原因是各個方面的,例如:在進行復合時,因為復合膠液自身色澤偏黃或偏紅,轉移至復合袋上會發生相應的偏色,影響其清晰度;如果資料自身清晰度差,有“霧狀”,也將影響其清晰度,因而在資料進倉時應該嚴把質量關,做到不合格質料不進倉。此外,不一樣的復合原資料清晰度也不一樣,如流延CPP的清晰度比吹塑共擠CPP的清晰度高得多。
              The reasons for the poor definition are various. For example, when compounding, because the color of the composite glue is yellow or red, the corresponding color deviation will occur when transferred to the composite bag, affecting its definition; If the clarity of the data itself is poor and "foggy", it will also affect its clarity. Therefore, the quality of the data should be strictly controlled when entering the warehouse, so that the unqualified materials will not enter the warehouse. In addition, the clarity of different composite raw materials is also different. For example, the clarity of tape casting CPP is much higher than that of blow molding co extrusion CPP.
