瓦楞紙(zhi)(zhi)(zhi)板(ban)生產中，各層(ceng)紙(zhi)(zhi)(zhi)板(ban)的張力(li)不(bu)平衡會(hui)引(yin)起紙(zhi)(zhi)(zhi)板(ban)縱向(xiang)(xiang)曲翹(qiao)，要注(zhu)(zhu)意(yi)調整好面紙(zhi)(zhi)(zhi)和(he)(he)(he)各層(ceng)紙(zhi)(zhi)(zhi)板(ban)的輸(shu)送張力(li)。不(bu)同(tong)(tong)的制(zhi)造設(she)備和(he)(he)(he)工藝生產的紙(zhi)(zhi)(zhi)張及不(bu)同(tong)(tong)產地的紙(zhi)(zhi)(zhi)張會(hui)有不(bu)同(tong)(tong)的收縮方向(xiang)(xiang)差異和(he)(he)(he)收縮率。不(bu)同(tong)(tong)進(jin)貨(huo)批次(ci)的紙(zhi)(zhi)(zhi)張和(he)(he)(he)堆放(fang)條(tiao)件差異會(hui)使(shi)紙(zhi)(zhi)(zhi)張的含水率不(bu)同(tong)(tong)。舊的輸(shu)送皮(pi)帶會(hui)因透氣不(bu)良而影(ying)響上(shang)層(ceng)紙(zhi)(zhi)(zhi)板(ban)的濕(shi)度揮發，同(tong)(tong)時還會(hui)使(shi)上(shang)層(ceng)紙(zhi)(zhi)(zhi)板(ban)吸收下(xia)層(ceng)紙(zhi)(zhi)(zhi)板(ban)散發的蒸(zheng)汽而產生吸濕(shi)變形，舊的生產線要注(zhu)(zhu)意(yi)防止忽略這(zhe)一因素。

如果了解其中的(de)原理和生(sheng)產線(xian)上(shang)各調節(jie)方(fang)法，通過仔細的(de)觀察和認真(zhen)分析，采取恰當的(de)措施進行(xing)調整，可以迅(xun)速(su)排(pai)除(chu)，須(xu)了解所用生(sheng)產線(xian)烘(hong)道穩定的(de)最高經濟(ji)運(yun)行(xing)速(su)度和熱(re)板(ban)正常溫度。
