瓦楞(leng)紙(zhi)(zhi)板(ban)(ban)(ban)(ban)生(sheng)產(chan)中，各層(ceng)紙(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)張(zhang)力不(bu)(bu)平衡會引起紙(zhi)(zhi)板(ban)(ban)(ban)(ban)縱向(xiang)曲翹，要注意調整好(hao)面紙(zhi)(zhi)和(he)各層(ceng)紙(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)輸送張(zhang)力。不(bu)(bu)同(tong)的(de)(de)制(zhi)造設(she)備(bei)和(he)工藝生(sheng)產(chan)的(de)(de)紙(zhi)(zhi)張(zhang)及(ji)不(bu)(bu)同(tong)產(chan)地的(de)(de)紙(zhi)(zhi)張(zhang)會有不(bu)(bu)同(tong)的(de)(de)收縮方(fang)向(xiang)差異和(he)收縮率。不(bu)(bu)同(tong)進貨批次的(de)(de)紙(zhi)(zhi)張(zhang)和(he)堆(dui)放(fang)條件(jian)差異會使(shi)紙(zhi)(zhi)張(zhang)的(de)(de)含水率不(bu)(bu)同(tong)。舊的(de)(de)輸送皮(pi)帶(dai)會因透氣不(bu)(bu)良而影響上(shang)層(ceng)紙(zhi)(zhi)板(ban)(ban)(ban)(ban)的(de)(de)濕度揮(hui)發，同(tong)時還(huan)會使(shi)上(shang)層(ceng)紙(zhi)(zhi)板(ban)(ban)(ban)(ban)吸(xi)收下層(ceng)紙(zhi)(zhi)板(ban)(ban)(ban)(ban)散發的(de)(de)蒸汽而產(chan)生(sheng)吸(xi)濕變形(xing)，舊的(de)(de)生(sheng)產(chan)線要注意防(fang)止忽略這(zhe)一因素。

如果了解其中的(de)(de)原理和生產(chan)線上(shang)各調節(jie)方法，通過(guo)仔(zi)細的(de)(de)觀察和認真分(fen)析，采取恰當的(de)(de)措施進行調整，可以迅(xun)速排除(chu)，須了解所(suo)用生產(chan)線烘道(dao)穩定的(de)(de)最高(gao)經(jing)濟運行速度(du)和熱板正常溫度(du)。
