Ihame rya Passivation yo Kwizirika hamwe ninama nziza zokuvura Antirust

Nyuma yicyuma kimaze kuvurwa hakoreshejwe okiside, igipimo cyo kwangirika kwicyuma kiri hasi cyane ugereranije nicyuma cyambere kitavuwe, cyitwa passivation yicyuma.

Muri rusange, passivation ihindura mubyukuri ibyuma bikora mubuso bwa inert binyuze mumiti ya chimique yumuti wa passiwasi, kugirango wirinde ibintu byangiza hanze bidakora hamwe nicyuma kandi bigere kumigambi yo kongera igihe cyicyuma. .

Ihame rya passivation

Ihame rya passivation rishobora gusobanurwa nigitekerezo cya firime yoroheje, ni ukuvuga ko bifatwa ko passivation iterwa no guhuza ibyuma nicyuma cya okiside, bizabyara firime yoroheje cyane (hafi 1nm), yuzuye, ifunze neza ya firime ya passivasi hejuru yicyuma, ishobora gufatanwa neza nicyuma. Iyi firime ibaho nkicyiciro cyigenga, mubisanzwe uruvange rwa ogisijeni nicyuma.

Irashobora gutandukanya rwose icyuma nigikoresho cyangirika, kandi ikabuza icyuma guhura nuburyo butangirika, kuburyo icyuma ahanini gihagarika gushonga kandi kigakora leta yoroheje kugirango igere ku ntego yo gukumira ruswa.

Ibiranga ibyiza na passivation:

Icyuma cya passiyo yicyuma ntigishobora guhindura ingano, ibara nuburyo bugaragara; Nta firime yamavuta ifatanye, kandi kurwanya ruswa nibyiza kandi bihamye (kuvura passivation nuburyo bwiza bwo gusimbuza imiti gakondo yo kurwanya ruswa kugirango ushire amavuta arwanya ingese). Ntibikenewe ibikoresho bidasanzwe hamwe nuburyo bukomeye bwo gutunganya, harasabwa gusa ibikoresho bike bya pulasitike cyangwa ibigega byuma bidafite ingese, kandi ikiguzi ni gito (2/3 munsi ugereranije no gutunganya hanze); Igikorwa kiroroshye, cyujuje cyane ibikenewe ninganda, kandi cyemeza ko buriwese ashobora kugikora, buriwese arashobora kugikora, kandi ashobora kugikora igihe icyo aricyo cyose. Gusa winjize imiyoboro muri marike ya Senyuan igisubizo kitagira ibyuma pasivation yumuti muminota 30 mubushyuhe bwicyumba.

Passivation:

Iyo screw imaze gutambuka, hazashyirwaho firime yuzuye ya passivation yuzuye kandi ifite ubwuzuzanye bwiza izakorwa hejuru yumurongo wa screw, ishobora gutuma iyo screw irwanya ruswa, kugeza kumasaha arenga 500 yo gupima umunyu.

Kuramo inzira ya passivation:

Banza ugabanye imigozi-ubyoze n'amazi atemba-ubikoreshe-ubyoze n'amazi atemba-ubitambike (muminota irenga 30) -ubisukuze n'amazi atemba-ubyoze n'amazi ya ultrapure uyumishe hanyuma ubipakire.
