單(dan)面(mian)蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)在(zai)單(dan)面(mian)蜂(feng)窩機(ji)(ji)及裱糊機(ji)(ji)處均(jun)要(yao)上(shang)(shang)膠(jiao),橫向伸(shen)長大,而(er)掛(gua)(gua)面(mian)紙(zhi)(zhi)(zhi)(zhi)(面(mian)紙(zhi)(zhi)(zhi)(zhi)張)因為(wei)(wei)直接(jie)與預(yu)熱(re)器跟雙面(mian)機(ji)(ji)的(de)(de)(de)平板(ban)(ban)(ban)(ban)烘缸接(jie)觸形成(cheng)過干燥狀(zhuang)況(kuang),進入雙面(mian)機(ji)(ji)的(de)(de)(de)冷卻部后成(cheng)為(wei)(wei)蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)送出(chu)(chu)。蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)裸露(lu)到(dao)空氣中,為(wei)(wei)達到(dao)水(shui)分(fen)(fen)均(jun)衡,水(shui)分(fen)(fen)大的(de)(de)(de)單(dan)面(mian)蜂(feng)窩側放出(chu)(chu)水(shui)分(fen)(fen),同時產生緊縮;而(er)干燥的(de)(de)(de)掛(gua)(gua)面(mian)紙(zhi)(zhi)(zhi)(zhi)接(jie)收(shou)水(shui)分(fen)(fen)而(er)伸(shen)長,因此產生上(shang)(shang)翹(qiao)(qiao)曲(qu)景象。若當(dang)上(shang)(shang)述情(qing)況(kuang)相反時(實際(ji)上(shang)(shang)是與平板(ban)(ban)(ban)(ban)烘缸的(de)(de)(de)干燥才干比(bi)(bi)較粘(zhan)合速度過快)則(ze)產生下翹(qiao)(qiao)。利用單(dan)面(mian)蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)掛(gua)(gua)面(mian)紙(zhi)(zhi)(zhi)(zhi)比(bi)(bi)蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)面(mian)紙(zhi)(zhi)(zhi)(zhi)水(shui)分(fen)(fen)多3%的(de)(de)(de)紙(zhi)(zhi)(zhi)(zhi)卷時,92%成(cheng)為(wei)(wei)上(shang)(shang)翹(qiao)(qiao)曲(qu)。利用蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)面(mian)紙(zhi)(zhi)(zhi)(zhi)水(shui)分(fen)(fen)比(bi)(bi)單(dan)蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)掛(gua)(gua)面(mian)紙(zhi)(zhi)(zhi)(zhi)水(shui)分(fen)(fen)多3%的(de)(de)(de)紙(zhi)(zhi)(zhi)(zhi)卷時,75%成(cheng)為(wei)(wei)下翹(qiao)(qiao)曲(qu)。故抉擇原(yuan)紙(zhi)(zhi)(zhi)(zhi)時,掛(gua)(gua)面(mian)紙(zhi)(zhi)(zhi)(zhi)(單(dan)面(mian)機(ji)(ji)的(de)(de)(de)掛(gua)(gua)面(mian)紙(zhi)(zhi)(zhi)(zhi)與蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)(de)面(mian)紙(zhi)(zhi)(zhi)(zhi))的(de)(de)(de)水(shui)分(fen)(fen)穩定必(bi)須堅(jian)持3%以內。作為(wei)(wei)解決上(shang)(shang)翹(qiao)(qiao)曲(qu),除了原(yuan)紙(zhi)(zhi)(zhi)(zhi)水(shui)分(fen)(fen)之外在(zai)蜂(feng)窩紙(zhi)(zhi)(zhi)(zhi)板(ban)(ban)(ban)(ban)機(ji)(ji)上(shang)(shang)還要(yao)留神:
1.增加(jia)單面(mian)蜂窩機(ji)處的預熱(re)機(ji)與預處理機(ji)的包角。
2.盡量(liang)(liang)減(jian)少(shao)單面蜂(feng)窩機的上膠量(liang)(liang)。
3.減少過(guo)橋(qiao)上單(dan)(dan)面蜂窩(wo)紙板的(de)沉積量(liang),盡(jin)可(ke)能堅持單(dan)(dan)面蜂窩(wo)機與雙面機的(de)速度一致(zhi)。
4.盡量(liang)減(jian)少蜂窩紙板在裱糊(hu)機(ji)處的上(shang)膠量(liang)。
