機械(xie)化造漿生產(chan)(chan)過程中(zhong)(zhong)雖然不使用(yong)(yong)(yong)化學藥(yao)品，腐蝕程度較輕，但造紙(zhi)(zhi)工業講(jiang)究(jiu)清潔，其機械(xie)設備(bei)如(ru)采(cai)用(yong)(yong)(yong)普通鋼(gang)鐵(tie)(tie)制(zhi)(zhi)造，使用(yong)(yong)(yong)時間(jian)長(chang)了(le)難免會產(chan)(chan)生鐵(tie)(tie)銹(xiu)，從而對(dui)紙(zhi)(zhi)漿產(chan)(chan)生污(wu)染(ran)，因此廣(guang)泛采(cai)用(yong)(yong)(yong)不銹(xiu)鋼(gang)制(zhi)(zhi)造。為了(le)在(zai)生產(chan)(chan)紙(zhi)(zhi)的(de)過程中(zhong)(zhong)減少污(wu)染(ran)和維修方(fang)便，如(ru)在(zai)造紙(zhi)(zhi)過程中(zhong)(zhong)使用(yong)(yong)(yong)的(de)冷(leng)卻塔、盛酸桶、蒸煮鍋等設備(bei)及管道，也廣(guang)泛采(cai)用(yong)(yong)(yong)不銹(xiu)鋼(gang)制(zhi)(zhi)造。其應用(yong)(yong)(yong)情(qing)況見表2-18。
