Passivation inzira yekudzikisa mwero wekuora kwesimbi nekushandura uso wayo kuita mamiriro asingatani kubatwa neoxidation. Mukuwedzera, chiitiko chesimbi inoshanda kana alloy, umo kemikari inoderedzwa zvakanyanya kusvika kune inoyevedza simbi, inonziwo passivation.
Passivation yesimbi munharaunda inowanikwa nenzira mbiri:
1. Chemical passivation: kunyanya kuburikidza nemakemikari anoita pakati pesimbi uye yakasimba oxidants, kuumbwa kwedense firimu ye oxides kana mamwe maumbirwo pamusoro pesimbi, iyo inovhara simbi yesimbi, inoparadzanisa simbi kubva pane mhinduro, nokudaro inodzivisa. simbi yacho Inoenderera mberi oxidation uye kupera.
2. Anodic passivation: inozivikanwawo se electrochemical passivation, yakafanana neanode yesimbi kana musanganiswa pasi pechiito chezvino, kune zvidimbu zvakasiyana, kurasikirwa nekwanisi yekuendesa kune mhinduro. Anodic passivation inokonzerwa neanodic polarization yesimbi passivation phenomenon, kureva, simbi iri pasi pechiito chezvino, electrode yayo inogona kuchinja uye kuumbwa kwesimbi oxides kana munyu pamusoro pe electrode, zvinhu izvi zvakavharwa zvakasimba mukati. iyo simbi pamusoro ive passivation firimu uye Inotungamira kune simbi passivation.
Kazhinji, kunyangwe makemikari passivation uye anodic passivation zvese zvinoshandura simbi yepasi kuita mamiriro asingatani kubatwa neoxidation, maitiro avo ekugadzira uye mashandisirwo emashure akasiyana. Chemical passivation inoumba firimu rekudzivirira pamusoro pesimbi kunyanya kuburikidza nekuita kwemakemikari, nepo anodic passivation ichiumba firimu rekufambisa pamusoro pesimbi kuburikidza ne electrochemical process, ese ari maviri akagadzirirwa kudzoreredza mwero wekuora kwesimbi.
Xiamen Guansheng Precision Machinery Co., Ltd. ine timu yehunyanzvi iyo inonyanya kugadzirisa zvikamu zvakasiyana-siyana zvinoenderana nezvaunoda.
