為減小瓦楞紙板的厚度損失，要從以下幾個方面進行控制：第一要生產出規定厚度的單面瓦楞，宿州優質聚酯方孔網首先在軋制瓦楞時要完全成型，其次在粘合襯紙定形單面瓦楞前要避免瓦芯波紋的回彈作用；第二在后續加工過程中要減少甚至避免瓦楞的變形。一、瓦楞紙板的厚度首先取決于瓦楞輥齒深的“先天”條件。優質聚酯方孔網濾布瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)一(yi)旦成(cheng)型(xing)(xing)就無法再增(zeng)加厚(hou)度(du)了。當上(shang)(shang)下(xia)(xia)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)輥(gun)(gun)(gun)(gun)(gun)互不(bu)平(ping)行，輥(gun)(gun)(gun)(gun)(gun)間加壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)不(bu)足(zu)，或(huo)在(zai)(zai)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)輥(gun)(gun)(gun)(gun)(gun)磨(mo)損(sun)以后(hou)(hou)，或(huo)在(zai)(zai)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)槽(cao)中夾有(you)異(yi)物(wu)，都會(hui)(hui)(hui)(hui)(hui)影響(xiang)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)波(bo)紋的(de)(de)(de)(de)(de)(de)完(wan)全成(cheng)型(xing)(xing)也就生產不(bu)出(chu)所(suo)要(yao)(yao)(yao)(yao)求厚(hou)度(du)的(de)(de)(de)(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)。二(er)、瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)扎(zha)制(zhi)(zhi)的(de)(de)(de)(de)(de)(de)完(wan)全成(cheng)型(xing)(xing)需(xu)要(yao)(yao)(yao)(yao)有(you)一(yi)定(ding)的(de)(de)(de)(de)(de)(de)條件，如扎(zha)制(zhi)(zhi)時(shi)(shi)芯紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)(de)溫度(du)及其(qi)(qi)水(shui)量等(deng)。在(zai)(zai)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)機(ji)(ji)的(de)(de)(de)(de)(de)(de)高(gao)速(su)運行中，單(dan)靠瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)輥(gun)(gun)(gun)(gun)(gun)的(de)(de)(de)(de)(de)(de)溫度(du)來加熱(re)(re)原紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)是(shi)不(bu)夠(gou)的(de)(de)(de)(de)(de)(de)。需(xu)先對瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)進(jin)行予熱(re)(re)，必要(yao)(yao)(yao)(yao)時(shi)(shi)要(yao)(yao)(yao)(yao)降低車(che)速(su)提高(gao)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)(de)扎(zha)制(zhi)(zhi)溫度(du)。當瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)過分(fen)潮(chao)濕時(shi)(shi)，扎(zha)制(zhi)(zhi)時(shi)(shi)不(bu)能(neng)(neng)很好(hao)(hao)的(de)(de)(de)(de)(de)(de)成(cheng)型(xing)(xing)，且影響(xiang)粘合效果(guo)。潮(chao)濕的(de)(de)(de)(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)原紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)缺少剛性(xing)，使(shi)(shi)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)不(bu)能(neng)(neng)挺立。在(zai)(zai)很小的(de)(de)(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)(li)作用(yong)(yong)下(xia)(xia)就會(hui)(hui)(hui)(hui)(hui)萎縮而增(zeng)加高(gao)度(du)損(sun)失。反之瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)原紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)過分(fen)干燥，紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)纖(xian)(xian)維的(de)(de)(de)(de)(de)(de)可(ke)(ke)塑性(xing)小，扎(zha)制(zhi)(zhi)時(shi)(shi)容易出(chu)現楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)高(gao)不(bu)足(zu)，即所(suo)謂低楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)。成(cheng)型(xing)(xing)后(hou)(hou)又容易回彈，涂膠后(hou)(hou)很快固(gu)化(hua)，不(bu)能(neng)(neng)將襯(chen)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)牢(lao)固(gu)地粘住。這(zhe)(zhe)時(shi)(shi)要(yao)(yao)(yao)(yao)對瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)噴射(she)低壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)高(gao)溫的(de)(de)(de)(de)(de)(de)蒸汽，造紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)網廠家(jia)將一(yi)定(ding)的(de)(de)(de)(de)(de)(de)水(shui)分(fen)逼入(ru)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的(de)(de)(de)(de)(de)(de)纖(xian)(xian)維內，增(zeng)加其(qi)(qi)可(ke)(ke)塑性(xing)以利于完(wan)全成(cheng)型(xing)(xing)。造紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)網廠家(jia)三、扎(zha)制(zhi)(zhi)成(cheng)型(xing)(xing)后(hou)(hou)的(de)(de)(de)(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)在(zai)(zai)后(hou)(hou)續加工過程中受到壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)力(li)(li)(li)，使(shi)(shi)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)沿楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)高(gao)方(fang)向變(bian)形甚至被壓(ya)(ya)(ya)(ya)(ya)(ya)(ya)垮(kua)，也會(hui)(hui)(hui)(hui)(hui)破壞(huai)(huai)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板(ban)的(de)(de)(de)(de)(de)(de)厚(hou)度(du)。（1）導紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)片的(de)(de)(de)(de)(de)(de)作用(yong)(yong)是(shi)將軋好(hao)(hao)的(de)(de)(de)(de)(de)(de)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)芯紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)在(zai)(zai)上(shang)(shang)膠與襯(chen)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)粘合前使(shi)(shi)其(qi)(qi)貼合在(zai)(zai)下(xia)(xia)瓦(wa)(wa)(wa)楞(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)(leng)輥(gun)(gun)(gun)(gun)(gun)的(de)(de)(de)(de)(de)(de)齒廓上(shang)
