造紙機干燥部的發展

1、DANGANTANGANZAOZHUANGZHI

傳統的多缸造紙機的干燥部都是上下兩層烘缸,雙干毯配置。為了有效地排出干燥部內的濕空氣,獲得良好的通風效果,要使用高透氣度的干毯。但這種高透氣度的干毯在有效排出濕空氣的同時也把強氣流帶入袋區,從而在生產低定量高速造紙機上產生了紙頁抖動問題,即在上下缸無支撐段的紙頁產生波動和拍打,在紙頁邊緣產生起皺和斷紙,在干燥部的濕端濕紙頁十分脆弱,非常易斷頭,且車速越高抖動越嚴重,越易斷頭。解決這個問題比較有效的辦法是采用單干毯配置。如圖6-2所示,取消了下干毯,上干毯帶著紙頁包繞上下烘缸。因此在上下烘缸之間的牽引部分,干毯也托著紙頁,紙頁不受牽引力作用,從而減輕紙頁抖動、起皺和斷頭。同時還消除了氣袋,紙頁橫向水分均勻了,省掉干毯輥,烘缸可以靠近力;紙頁是在無牽引下干燥,避免了因受牽引干燥時的縱向被過分拉長和橫向過分收縮現象,可以提高成紙質量。
