如何鑒定無紡布袋塑料扣質量的好壞

　　如何鑒定無紡布袋塑料扣質量的好壞：
　　How to identify plastic buckles quality non-woven bag:
　　1、用手折取一段扣板，用兩手抓住橫向、縱向折彎，如果是劣質板材，則很容易折斷崩裂；而質優的板材，則不會出現這種情況，即使產生永久性變形也不會折斷或崩裂。
　　1, with versatile take a gusset plate, with transverse and longitudinal bending, positioned if is inferior plank, it's easy to broken split; And good quality of the plate, it's not the case, even if is not broken or split to produce permanent deformation.
　　2、用指甲試劃印花面印花扣板的印刷圖案上面有一層上光膜，起保護圖案和花紋的作用，該光膜必須有一定的硬度，才能耐磨擦。濟南無紡布袋
　　2, try nail row printing surface printing with a layer of gusset plate of printing design polish film, plays a role of protection design and decorative pattern, the optical film must have a certain hardness, friction to ability.
　　要檢查光膜的硬度，可以用指甲在光膜表面來回試劃，然后觀察是否會留下劃痕。一般來說，優質的扣板是不會留下劃痕的，如果出現劃痕，說明保護印刷圖案的上光膜的硬度不好，使用中容易劃傷。
　　To check that the light film hardness, nail can be used in optical try back and forth across the membrane surface, and then see if will leave scratches. Generally speaking, the quality of gusset plate will not leave scratches, if there is a scratch, that protect the printing design of polish film hardness is not good, use easy to scratch.
　　3、查看鋸口及板內表面的粗糙程度質量好的扣板，強度及韌性都好，板面及內筋等部位在鋸斷時，不會出現崩口，且鋸口平齊，無毛刺、裂紋等現象，內表面及內筋斷面平滑，不會有明顯的氣泡。劣質扣板鋸口會出現毛刺，內筋及板的上下面容易出現崩口、裂紋，而且內表面粗糙，內筋上氣泡多。
　　3, check the curf and inner surface roughness of good quality gusset plate, plate strength and toughness is good, in areas such as the surface and inner rib in sawing, won't appear crack, and curf flush, burr, the phenomenon such as crack, inner surface and inner rib section smooth, does not have obvious bubbles. Can appear shoddy
