PVC封(feng)邊(bian)(bian)(bian)條使用(yong)過(guo)程中(zhong),如(ru)果(guo)是手工封(feng)邊(bian)(bian)(bian)機(ji)(ji)或是半自動封(feng)邊(bian)(bian)(bian)機(ji)(ji),修邊(bian)(bian)(bian)會有發白現(xian)象(xiang),是因為設備沒有拋(pao)光功能的緣故,屬正常(chang)現(xian)象(xiang)。封(feng)邊(bian)(bian)(bian)過(guo)程中(zhong),如(ru)果(guo)0.6MM以下厚度封(feng)邊(bian)(bian)(bian)條有發軟,拉伸,變形,承受不了高溫(wen)現(xian)象(xiang),是因為封(feng)邊(bian)(bian)(bian)速(su)度過(guo)慢(man),熱熔膠(jiao)熔化后滯留時間過(guo)長所致,可用(yong)加快封(feng)邊(bian)(bian)(bian)速(su)度,高速(su)傳送帶速(su)度,調整(zheng)涂膠(jiao)量來改善,參考速(su)度8M/分以上,如(ru)果(guo)是雙面(mian)涂膠(jiao)的封(feng)邊(bian)(bian)(bian)機(ji)(ji),這種現(xian)象(xiang)一般較少發生。
