Simbi isina nguramapaipi akaiswa simbi, akarebesa denderedzwa simbi zvinhu zvinonyanya kushandiswa mumaindasitiri akadai se peturu, makemikari, simba renyukireya, uye hutano hwehutano.Mushandisi weTikTok anosiya meseji, "Pane hukama pakati pekushandiswa kwesimbi isina tsvina mapaipi akaiswa musimba renyukireya uye passivation?"
Pakusarudza zvinhu uye nzira dzekugadzira simbi isina tsvina iyo inoshandiswa mumidziyo yemukati uye recirculation system pombi mumareactor, kutarisisa kwakanyanya kunofanirwa kupihwa kudzvanyirira kushushikana kwecorrosion kupaza uye kuderedza kukanganiswa kwemwaranzi.
Kazhinji, kukwidziridza kusimba kwekupokana kwesimbi isina simbi yakashongedzwa pombi, nzira mbiri dzinowanzoshandiswa:passivation uye electrolysis.Kumapombi esimbi asina tsvina akaiswa musimba renyukireya, kuchengetedzwa kwecorrosion kunowanzobatanidza kurapwa kwepasi (uchishandisa simbi isina simbi passivation solution).Passivation inzira nyowani seimwe nzira yemafuta ekudzivirira ngura.Nheyo iyi inosanganisira kushandisa oxidizing agents mune passivation mhinduro (stainless simbi passivation mhinduro) kushandura inoshingaira simbi ions pamusoro pesimbi pevhu kuita passive mamiriro.Izvi zvinonyatso kunonoka kuparara kwesimbi.Passivation ndeye microchemical reaction iyo isingashandure chimiro chemolecular yezvinhu.Inongobatanidza okisijeni neanoshanda simbi zvinhu muchinhu, ichigadzira simbi oxide.Iyi oxide layer iri mune passive state, ichiita sechivharo pakati pesimbi neyakaora svikiro, kudzivirira kudhumhana kwakananga uye kumisa simbi kubva pakunyungudika, kuwana inodiwa kudzivirira ngura.
EST Chemical Groupyave ichienderera mberi nekuvandudza, kugadzirisa passivation (Stainless simbi passivation solution) uye matambudziko ekudzivirira ngura kune vatengi.Isu tinopa emhando yepamusoro, yekucheka-kumucheto zvigadzirwa uye tinopa yakazara seti yepassivation mhinduro dzakarongedzerwa kuzadzisa izvo zvakasarudzika zvinodiwa nevatengi.
