機械(xie)化造漿生(sheng)產(chan)過(guo)程中(zhong)(zhong)雖然不(bu)使(shi)用(yong)(yong)(yong)化學藥品，腐蝕程度較輕，但造紙工業講究清潔，其機械(xie)設(she)備如(ru)采(cai)用(yong)(yong)(yong)普(pu)通鋼鐵(tie)制(zhi)造，使(shi)用(yong)(yong)(yong)時間長(chang)了難免會(hui)產(chan)生(sheng)鐵(tie)銹，從而對紙漿產(chan)生(sheng)污(wu)染(ran)，因此(ci)廣泛采(cai)用(yong)(yong)(yong)不(bu)銹鋼制(zhi)造。為了在生(sheng)產(chan)紙的過(guo)程中(zhong)(zhong)減少污(wu)染(ran)和維(wei)修方(fang)便，如(ru)在造紙過(guo)程中(zhong)(zhong)使(shi)用(yong)(yong)(yong)的冷卻(que)塔、盛酸桶、蒸煮鍋等設(she)備及管道，也(ye)廣泛采(cai)用(yong)(yong)(yong)不(bu)銹鋼制(zhi)造。其應用(yong)(yong)(yong)情況見(jian)表2-18。
