        紙(zhi)(zhi)管(guan)(guan)(guan)即紙(zhi)(zhi)張加工(gong)(gong)(gong)成(cheng)的(de)管(guan)(guan)(guan)狀的(de)物體，大多(duo)紙(zhi)(zhi)管(guan)(guan)(guan)為(wei)螺(luo)旋紙(zhi)(zhi)管(guan)(guan)(guan)和(he)(he)無縫紙(zhi)(zhi)管(guan)(guan)(guan)。紙(zhi)(zhi)管(guan)(guan)(guan)按照用(yong)(yong)途(tu)可(ke)以(yi)分為(wei)化(hua)纖工(gong)(gong)(gong)業(ye)用(yong)(yong)管(guan)(guan)(guan)、折(zhe)疊(die)薄膜工(gong)(gong)(gong)業(ye)用(yong)(yong)管(guan)(guan)(guan)、印刷工(gong)(gong)(gong)業(ye)用(yong)(yong)管(guan)(guan)(guan)、造紙(zhi)(zhi)工(gong)(gong)(gong)業(ye)用(yong)(yong)管(guan)(guan)(guan)、冶金工(gong)(gong)(gong)業(ye)用(yong)(yong)管(guan)(guan)(guan)、包裝(zhuang)用(yong)(yong)管(guan)(guan)(guan)、測溫(wen)用(yong)(yong)紙(zhi)(zhi)管(guan)(guan)(guan)、取樣器用(yong)(yong)紙(zhi)(zhi)管(guan)(guan)(guan)、傳(chuan)真機(ji)用(yong)(yong)紙(zhi)(zhi)管(guan)(guan)(guan)、電池紙(zhi)(zhi)管(guan)(guan)(guan)、橋梁建筑用(yong)(yong)管(guan)(guan)(guan)和(he)(he)煙花爆竹用(yong)(yong)管(guan)(guan)(guan)等等。

       傳統(tong)紙管(guan)烘干方式的現(xian)狀和不足

　　1.大規(gui)模較大工廠多采用電(dian)(dian)加熱(re)(re)烤(kao)房，耗電(dian)(dian)大，成(cheng)本高；電(dian)(dian)加熱(re)(re)烘(hong)干方式(shi)溫度較高，容易(yi)導(dao)致紙管受(shou)熱(re)(re)不(bu)均勻的現象而出差變形分(fen)層(ceng)脫膠。電(dian)(dian)加熱(re)(re)的過高溫度，嚴重的時候甚至會(hui)引(yin)起烤(kao)糊安全程度低；一(yi)般的發熱(re)(re)管壽命(ming)為(wei)三(san)到五個月，維修更換(huan)頻繁。

　　2.部分(fen)工廠采用蒸汽烘(hong)(hong)干，溫濕度難以(yi)控制，在紙管烘(hong)(hong)干過程中(zhong)，容易(yi)導致溫度過高而(er)產生烘(hong)(hong)干品質(zhi)問題。

　　3.小規模(mo)的(de)工廠使用自然曬干(gan)或者(zhe)風干(gan)的(de)辦(ban)法。生產周期(qi)長，效率低(di)。受(shou)天氣影響很大，不能連(lian)續生產，勞動(dong)強(qiang)度大，烘干(gan)的(de)質量(liang)難以有效控制。

       紙管采用熱泵(beng)烘干的優(you)勢

 　　空氣源熱(re)泵烘干(gan)(gan)可以有(you)效(xiao)地(di)(di)保證被(bei)烘干(gan)(gan)物料的(de)(de)(de)物理和化學特(te)性(xing)及烘干(gan)(gan)物料的(de)(de)(de)質量(liang)；對(dui)紙管進行烘干(gan)(gan)時熱(re)風分布均勻，烘干(gan)(gan)速度(du)快，產量(liang)大；全自(zi)(zi)動化的(de)(de)(de)控制(zhi)系統，溫度(du)分布均勻，濕度(du)可以自(zi)(zi)動控制(zhi)，免人員看(kan)守；安全可靠，烘干(gan)(gan)過(guo)程不存在對(dui)人造成傷害的(de)(de)(de)危險，按設置時間烘干(gan)(gan)完畢之(zhi)后自(zi)(zi)動停機；烘干(gan)(gan)過(guo)程能耗低，有(you)效(xiao)地(di)(di)減(jian)少運行成本；通用性(xing)強(qiang)，減(jian)少了投(tou)資費用的(de)(de)(de)同(tong)時，提高了設備(bei)的(de)(de)(de)利用率和有(you)效(xiao)使用率。

       奧伯特江蘇揚州紙管烘(hong)干案例分享

　　江蘇(su)揚州(zhou)某紙管加工廠原來采用的(de)是電烘房，采用奧伯特熱泵(beng)烘干(gan)(gan)后(hou)比(bi)原來節能60%～70%，項目配置了兩臺7P的(de)上送風空氣源(yuan)熱泵(beng)烘干(gan)(gan)機組，烤房尺寸(cun)5m*5m*4.8m，一次性可烘干(gan)(gan)紙管5～6噸。據(ju)負責(ze)該項目的(de)奧伯特安(an)徽(hui)辦事處(chu)吳總介紹，紙筒在生產(chan)過程中(zhong)，烘干(gan)(gan)是非常重要的(de)工序，而紙管的(de)烘干(gan)(gan)一般分三段：第一段溫度設置為45℃，第二(er)段將溫度逐漸(jian)上升至55℃～60℃，然后(hou)是70℃～75℃。

　　另外，在紙(zhi)(zhi)(zhi)筒(tong)(tong)烘干(gan)(gan)過(guo)程中需(xu)要注意以(yi)(yi)下幾個(ge)問題：紙(zhi)(zhi)(zhi)筒(tong)(tong)烘干(gan)(gan)的(de)溫度(du)(du)應根據(ju)(ju)紙(zhi)(zhi)(zhi)管的(de)厚度(du)(du)進行(xing)(xing)設置；排濕(shi)方面(mian)，主要是紙(zhi)(zhi)(zhi)筒(tong)(tong)層合(he)生產時(shi)(shi)候用于粘(zhan)結(jie)的(de)膠水，所(suo)以(yi)(yi)紙(zhi)(zhi)(zhi)筒(tong)(tong)中含(han)水量不(bu)(bu)大(da)，進行(xing)(xing)控(kong)制排濕(shi)可以(yi)(yi)節省(sheng)能(neng)(neng)耗(hao)；根據(ju)(ju)紙(zhi)(zhi)(zhi)筒(tong)(tong)的(de)軸徑大(da)小(xiao)、厚度(du)(du)大(da)小(xiao)、膠水性能(neng)(neng)等(deng)因素，紙(zhi)(zhi)(zhi)筒(tong)(tong)烘干(gan)(gan)的(de)一般時(shi)(shi)間(jian)4～10個(ge)小(xiao)時(shi)(shi)不(bu)(bu)等(deng)，烘干(gan)(gan)過(guo)程中必須(xu)控(kong)制紙(zhi)(zhi)(zhi)筒(tong)(tong)軸向和(he)徑向的(de)變形量；烘干(gan)(gan)成(cheng)品的(de)硬度(du)(du)和(he)強度(du)(du)是紙(zhi)(zhi)(zhi)筒(tong)(tong)品質的(de)重要指(zhi)標，由于紙(zhi)(zhi)(zhi)管的(de)大(da)小(xiao)、厚薄以(yi)(yi)及材質存在著一定差異，所(suo)以(yi)(yi)烘干(gan)(gan)時(shi)(shi)間(jian)和(he)工(gong)藝也需(xu)要做出相應的(de)調整。
