機(ji)械(xie)化造(zao)漿(jiang)生產(chan)過(guo)(guo)程中(zhong)(zhong)雖(sui)然不使(shi)用(yong)(yong)(yong)化學藥品，腐蝕程度較輕，但造(zao)紙(zhi)工業講(jiang)究清潔，其機(ji)械(xie)設(she)備如(ru)采用(yong)(yong)(yong)普通鋼(gang)鐵(tie)制(zhi)造(zao)，使(shi)用(yong)(yong)(yong)時間長(chang)了難免會產(chan)生鐵(tie)銹，從而對紙(zhi)漿(jiang)產(chan)生污(wu)染，因此廣(guang)泛(fan)(fan)采用(yong)(yong)(yong)不銹鋼(gang)制(zhi)造(zao)。為(wei)了在生產(chan)紙(zhi)的過(guo)(guo)程中(zhong)(zhong)減(jian)少污(wu)染和維修(xiu)方便，如(ru)在造(zao)紙(zhi)過(guo)(guo)程中(zhong)(zhong)使(shi)用(yong)(yong)(yong)的冷卻(que)塔(ta)、盛酸桶(tong)、蒸(zheng)煮(zhu)鍋等設(she)備及(ji)管道，也廣(guang)泛(fan)(fan)采用(yong)(yong)(yong)不銹鋼(gang)制(zhi)造(zao)。其應用(yong)(yong)(yong)情況見表2-18。
