The improvements of packaging paper strengths,including stiffness,ring crush compression resistance,folding endurance and tensile strength,by novel strengthening agents was investigated.
该文探讨了用新型增强剂提高纸页的包装强度:挺度、环压强度、耐折度、抗张强度;比较了几种增强剂对提高纸页包装强度的效果,确定了最合适的增强剂及用量,并研究了最合适的增强剂对不同纸浆、不同定量纸页包装强度的影响,确定采用4号增强剂且用量为0。
Physical properties as base weight, brightness, tear resistance, tensile strength, folding endurance, chromaticity, were measured.
为确证电子束辐照邮件的安全性,探索辐照纸张时可保证品种等级的剂量范围,在不同剂量下,用电子束照射新闻纸、复印纸、牛皮纸、书写纸、照片等几种常用的纸张,测定了纸张的定量、白度、撕裂度、抗张强度、耐折度、色差等物理性能在辐照后发生的变化。
It is very useful to improve FPCB flexibility and select suitable FCCL for FPC by researching folding endurance of different three layer-FCCL structures.
耐折性是一种评价挠性覆铜板挠曲可靠性的一种快速手段。
