　　耐(nai)水瓦楞(leng)紙(zhi)板(ban)制造(zao)工(gong)藝：在(zai)(zai)瓦楞(leng)紙(zhi)板(ban)粘合過(guo)程中(zhong)，把耐(nai)水性的(de)防水涂料用噴(pen)涂法(fa)或滾涂法(fa)涂布(bu)在(zai)(zai)張紙(zhi)表(biao)面上，使(shi)紙(zhi)板(ban)具有(you)良好的(de)耐(nai)水性。強(qiang)耐(nai)水性瓦楞(leng)紙(zhi)板(ban)—這種紙(zhi)板(ban)長時(shi)間和(he)水接觸，也幾乎不透水。強(qiang)耐(nai)水性瓦楞(leng)紙(zhi)板(ban)制造(zao)方法(fa)有(you)兩種：一是一次加(jia)工(gong)法(fa)，即在(zai)(zai)抄紙(zhi)階段就賦(fu)予原(yuan)紙(zhi)以耐(nai)水性;還有(you)二(er)次加(jia)工(gong)法(fa)，即采用涂布(bu)法(fa)和(he)浸漬法(fa)在(zai)(zai)瓦楞(leng)紙(zhi)板(ban)制造(zao)階段賦(fu)予以耐(nai)水性。

　　瓦楞紙板紙箱的防水性(xing)能可以采取(qu)以下(xia)方法進行檢測：

　　采(cai)用可勃(bo)吸收儀(yi)測(ce)定法(fa)(僅(jin)適合疏水瓦(wa)楞(leng)(leng)紙(zhi)(zhi)板(ban)和耐水瓦(wa)楞(leng)(leng)紙(zhi)(zhi)板(ban))采(cai)用可勃(bo)吸收儀(yi)可以(yi)用來測(ce)定瓦(wa)楞(leng)(leng)紙(zhi)(zhi)板(ban)的表面吸水能力，按照GB/T紙(zhi)(zhi)和紙(zhi)(zhi)板(ban)吸水性的測(ce)定(可勃(bo)法(fa))》執行。將瓦(wa)楞(leng)(leng)紙(zhi)(zhi)板(ban)切成(cheng)直徑為125mm的圓(yuan)形試(shi)片10張，在安(an)放瓦(wa)楞(leng)(leng)紙(zhi)(zhi)板(ban)試(shi)樣前，要保(bao)證同試(shi)樣接(jie)觸(chu)的圓(yuan)筒環面與膠(jiao)墊是干燥的。

　　用(yong)玻璃(li)量(liang)筒(tong)(tong)準確量(liang)取100mL蒸餾水(shui)(shui)倒入圓筒(tong)(tong)中，然后(hou)(hou)將(jiang)已(yi)稱好重(zhong)量(liang)的(de)圓形瓦楞紙(zhi)(zhi)板試(shi)樣(yang)(yang)(yang)(yang)安放(fang)于(yu)圓筒(tong)(tong)的(de)環形面(mian)(mian)上(shang)(shang)，被測面(mian)(mian)朝著有(you)水(shui)(shui)的(de)方向，并將(jiang)試(shi)樣(yang)(yang)(yang)(yang)壓(ya)蓋(gai)蓋(gai)在(zai)試(shi)樣(yang)(yang)(yang)(yang)上(shang)(shang)，使之于(yu)圓筒(tong)(tong)固定在(zai)一起。將(jiang)圓筒(tong)(tong)翻轉180°，同時(shi)開(kai)動秒表(biao)計(ji)時(shi)。每測定5次，根(gen)據瓦楞紙(zhi)(zhi)板試(shi)樣(yang)(yang)(yang)(yang)的(de)吸(xi)(xi)(xi)水(shui)(shui)量(liang)大小(xiao)再補加一定量(liang)的(de)水(shui)(shui)。從(cong)圓筒(tong)(tong)上(shang)(shang)取下試(shi)樣(yang)(yang)(yang)(yang)，放(fang)在(zai)一張(zhang)(zhang)吸(xi)(xi)(xi)水(shui)(shui)紙(zhi)(zhi)上(shang)(shang)，注(zhu)意試(shi)樣(yang)(yang)(yang)(yang)吸(xi)(xi)(xi)水(shui)(shui)面(mian)(mian)向下，在(zai)到達(da)吸(xi)(xi)(xi)水(shui)(shui)時(shi)間前(qian)2s時(shi)，再在(zai)試(shi)樣(yang)(yang)(yang)(yang)上(shang)(shang)面(mian)(mian)放(fang)兩張(zhang)(zhang)吸(xi)(xi)(xi)水(shui)(shui)紙(zhi)(zhi)，在(zai)平(ping)整堅(jian)硬的(de)臺(tai)子上(shang)(shang)用(yong)光滑壓(ya)輥在(zai)4s內往返一次，使試(shi)樣(yang)(yang)(yang)(yang)表(biao)面(mian)(mian)呈無水(shui)(shui)光澤，把試(shi)樣(yang)(yang)(yang)(yang)迅速取出稱量(liang)，準確至0.001g，注(zhu)意每張(zhang)(zhang)試(shi)樣(yang)(yang)(yang)(yang)只能測試(shi)一次，不得(de)重(zhong)復使用(yong)。對(dui)于(yu)用(yong)吸(xi)(xi)(xi)水(shui)(shui)紙(zhi)(zhi)吸(xi)(xi)(xi)水(shui)(shui)后(hou)(hou)表(biao)面(mian)(mian)仍有(you)過(guo)量(liang)水(shui)(shui)或試(shi)樣(yang)(yang)(yang)(yang)本身(shen)已(yi)被水(shui)(shui)透(tou)過(guo)，則應舍棄該試(shi)樣(yang)(yang)(yang)(yang)。就可以計(ji)算(suan)出瓦楞紙(zhi)(zhi)板的(de)可勃(bo)吸(xi)(xi)(xi)水(shui)(shui)值。
