紙(zhi)管(guan)烘(hong)干是紙(zhi)管(guan)生產(chan)的(de)重(zhong)要(yao)環節(jie)，將卷(juan)管(guan)時的(de)膠水蒸發出去，使紙(zhi)管(guan)成型后更穩(wen)定，直接決定紙(zhi)管(guan)形狀及硬度(du)，有些紙(zhi)管(guan)使用的(de)地方是高(gao)速旋(xuan)轉的(de)，膠水沒有烘(hong)干生產(chan)過程中會散掉(diao)。下面(mian)由紙(zhi)管(guan)廠(chang)家(jia)就來給大家(jia)講(jiang)一(yi)講(jiang)紙(zhi)管(guan)烘(hong)干的(de)工序及注意事項有哪些?

紙(zhi)(zhi)(zhi)(zhi)(zhi)管(guan)在生(sheng)產(chan)過(guo)程中是將本身含有一(yi)定(ding)水分的紗管(guan)紙(zhi)(zhi)(zhi)(zhi)(zhi)，再涂上膠(jiao)(jiao)液卷(juan)制而成(cheng)，這(zhe)樣(yang)卷(juan)管(guan)時剛卷(juan)出(chu)來的紙(zhi)(zhi)(zhi)(zhi)(zhi)管(guan)處于(yu)一(yi)種(zhong)濕的狀態，這(zhe)時的徑向(xiang)(xiang)(xiang)抗壓強(qiang)度(du)很低(di)，要(yao)想提高，必須通過(guo)烘(hong)干(gan)將水分蒸發(fa)出(chu)去才行(xing)，所以，烘(hong)干(gan)對紙(zhi)(zhi)(zhi)(zhi)(zhi)管(guan)徑向(xiang)(xiang)(xiang)抗壓強(qiang)度(du)的影響(xiang)至關重要(yao)。剛卷(juan)出(chu)來的紙(zhi)(zhi)(zhi)(zhi)(zhi)管(guan)還處于(yu)一(yi)種(zhong)不穩定(ding)狀態，如(ru)果立即(ji)烘(hong)干(gan)，膠(jiao)(jiao)帶(dai)紙(zhi)(zhi)(zhi)(zhi)(zhi)管(guan)生(sheng)產(chan)廠家(jia)，勢必造成(cheng)膠(jiao)(jiao)液還未被(bei)紙(zhi)(zhi)(zhi)(zhi)(zhi)吸收，就被(bei)烘(hong)干(gan)，膠(jiao)(jiao)液存留于(yu)紙(zhi)(zhi)(zhi)(zhi)(zhi)層之間，變(bian)成(cheng)固(gu)化物，這(zhe)樣(yang)將導(dao)致紙(zhi)(zhi)(zhi)(zhi)(zhi)層結合(he)疏松，徑向(xiang)(xiang)(xiang)抗壓強(qiang)度(du)降低(di)，所以首先應將紙(zhi)(zhi)(zhi)(zhi)(zhi)管(guan)在自然環境中放置1小(xiao)時左(zuo)右(you)，再進(jin)行(xing)烘(hong)干(gan)。烘(hong)干(gan)時注(zhu)意，常(chang)州膠(jiao)(jiao)帶(dai)紙(zhi)(zhi)(zhi)(zhi)(zhi)管(guan)，起(qi)初溫度(du)不能過(guo)高，保持(chi)在40～50℃左(zuo)右(you)，使紙(zhi)(zhi)(zhi)(zhi)(zhi)管(guan)內外受熱(re)均勻(yun)，大(da)約(yue)持(chi)續(xu)1.5小(xiao)時左(zuo)右(you)，溫度(du)可(ke)升高，不再控(kong)制。

烘干過(guo)程中要保(bao)證烘房各部(bu)分溫度(du)(du)均勻。間隔固定(ding)的(de)時間對烘房內(nei)各點紙(zhi)管(guan)(guan)(guan)進行(xing)抽(chou)查，通常在(zai)氣候干燥(zao)時，烘去卷(juan)管(guan)(guan)(guan)重(zhong)量的(de)8%;潮濕(shi)季節(jie)烘去卷(juan)管(guan)(guan)(guan)重(zhong)量的(de)10%左右，紙(zhi)管(guan)(guan)(guan)的(de)徑(jing)向(xiang)抗(kang)(kang)壓(ya)強度(du)(du)即可達到較佳狀態，烘的(de)太輕(qing)或太重(zhong)都將(jiang)降低紙(zhi)管(guan)(guan)(guan)的(de)徑(jing)向(xiang)抗(kang)(kang)壓(ya)強度(du)(du)。

1： 粘合(he)力(li)度大：好的紙管廠一(yi)般(ban)來說所制造的紙管抗壓強度、耐水性、抗凍服從比(bi)另(ling)外膠種(zhong)生制造的紙管更！

2： 耐寒性(xing)好，膠(jiao)帶(dai)紙(zhi)管價格，0 ℃ 的前(qian)提下流動(dong)性(xing)較好，不受(shou)任何(he)的影響。

3： 水(shui)(shui)分蒸(zheng)發快，制造的紙管縮水(shui)(shui)率低(di)、變型小、成品(pin)率高；

4： 新型(xing)紙(zhi)管(guan)膠(jiao)為水性(xing)制造(zao)品，用起(qi)來平安，膠(jiao)帶紙(zhi)管(guan)定做，不(bu)容(rong)易狀況污染。

5： 貯存(cun)堅(jian)定服從好，室溫存(cun)放3個月以(yi)上(shang)不分層(ceng)、剛(gang)烈質。

6： 綠色環(huan)保：該紙管膠暫時使(shi)用對人體無害(hai)，制(zhi)造(zao)(zao)(zao)品生(sheng)制(zhi)造(zao)(zao)(zao)合適企(qi)業生(sheng)制(zhi)造(zao)(zao)(zao)標(biao)準；

7： 紙管的固含(han)量大，大大擴大了(le)干(gan)燥(zao)時間，緊縮(suo)了(le)生制造周期。

紙(zhi)管(guan)(guan)在(zai)很(hen)多的(de)(de)行業(ye)都有較大的(de)(de)用(yong)(yong)(yong)處(chu)，例如化(hua)纖工(gong)業(ye)用(yong)(yong)(yong)的(de)(de)管(guan)(guan)dty管(guan)(guan)、poy管(guan)(guan)、fdy管(guan)(guan)、錦綸管(guan)(guan)、氨(an)綸管(guan)(guan)、氨(an)綸包(bao)覆(fu)紗管(guan)(guan)等(deng)(deng)(deng)，薄膜(mo)工(gong)業(ye)用(yong)(yong)(yong)管(guan)(guan)等(deng)(deng)(deng)，印刷工(gong)業(ye)主要應用(yong)(yong)(yong)于卷桶印刷、薄膜(mo)印刷、紙(zhi)張(zhang)印刷的(de)(de)用(yong)(yong)(yong)管(guan)(guan)等(deng)(deng)(deng)，皮革(ge)工(gong)業(ye)用(yong)(yong)(yong)管(guan)(guan)pu革(ge)、地毯革(ge)。食品(pin)包(bao)裝用(yong)(yong)(yong)管(guan)(guan)荼葉(xie)罐(guan)、薯片罐(guan)、糖(tang)果罐(guan)、蛋糕盒管(guan)(guan)，冶(ye)金工(gong)業(ye)用(yong)(yong)(yong)管(guan)(guan)建(jian)筑行業(ye)用(yong)(yong)(yong)管(guan)(guan)代替殼(ke)子板用(yong)(yong)(yong)管(guan)(guan)展(zhan)覽行業(ye)用(yong)(yong)(yong)管(guan)(guan)展(zhan)鑒用(yong)(yong)(yong)柱紙(zhi)管(guan)(guan)等(deng)(deng)(deng)等(deng)(deng)(deng)。紙(zhi)管(guan)(guan)被(bei)越來(lai)越多的(de)(de)運用(yong)(yong)(yong)到工(gong)業(ye)生產和生活中(zhong)去。
