Uburyo busanzwe bwo kuvura ibyuma bidafite ikibazo

Ihame: Kubijyanye no kuvura imiti, igice cya oxide cyakozwe hejuru yicyuma, kandi ubuvuzi bwo hejuru bugerwaho binyuze muri firime ya oxide. Ihame ryakoreshejwe muri ubu buryo bwo kuvura hejuru ni ugukora film ya oxide hejuru yicyuma munsi y'ibikoresho bihuye, bishobora gutandukanya ibyuma bihuye nabyo bijyanye nibidukikije.

Uburyo busanzwe bwo gucana ibyuma bidafite ishingiro ni ibi bikurikira:

Icyiciro 1: Uburyo bwa Acide

(1) Uburyo bwa Ditete de? Ibice byibitangaza byicyuma muri Sodium ya Sodium Diich Ditromée hanyuma ukangure neza muminota 20-30 kugirango ukore film yirabura. Kuraho kandi ukonje, hanyuma woge amazi.

(2) Uburyo bwirabura bwa chemate. Inzira yo guhindura ibara ryiyi firime urwego ruva mumucyo wijimye. Iyo ihindutse mubururu bwumucyo kugeza ubururu bwimbitse (cyangwa umukara utanduye), igihe intera ni iminota 0.5-1 gusa. Niba iyi ngingo nziza yabuze, izagaruka kumurika yoroheje kandi irashobora kuvaho gusa no kongera ibara.

2. Uburyo bwa Gusubiramo burashobora kubona firime nziza yumukara, ikeneye gutoranya na aqua regia mbere yuko okiside

3. Uburyo bwa Alkaline. Alkaline okidation nigisubizo cyateguwe na sodium hydroxide, hamwe nigihe cya okiside yiminota 10-15. Filime yumukara yirabura ifite kwambara neza kandi ntibisaba kuvurwa. Igihe cyumunyu mugihe muri rusange kiri hagati yamasaha 600-800. Irashobora kugumana ireme ryiza ryibyuma bidafite ikibazo nta rutare.

Icyiciro cya 2: Uburyo bwa electrolytic

Gutegura igisubizo: (20-40G / L Diichromate, 10-40g / l manganese sulfate, 10-20G / L BORIC ACID, 10-20G / L / PH3-4). Filime y'amabara yashizwemo igisubizo cya 10% kuri 25c kuminota 5, kandi nta jambo ryahindutse cyangwa gukuramo firime yimbere, byerekana ko firime yimbere, yerekana kurwanya ruswa. Nyuma ya electrolysis, 1cr17 ibyuma bidafite umuyoboro byanduye ni umujinya vuba, hanyuma ukomanga kugirango ubone firime yumukara wirabura ifite ibara ryirabura ifite ibara rimwe, elastique, nurwego runaka rwo gukomera. Ibiranga ni inzira yoroshye, umuvuduko wihuse wo gucana, ingaruka nziza, hamwe no kurwanya imyanda. Birakwiriye kuvura amabuye ya brails yibimera bitandukanye kandi rero bifite agaciro gakomeye.

Icyiciro cya 3: Uburyo bwo kuvura ubushyuhe bwa qpq

Bikozwe mubikoresho byihariye, urwego rwa firime rurakomeye kandi rufite imbaraga nziza; Ariko, bitewe nuko ibyuma bitagira ingano, cyane cyane ibyuma bidafite ibyuma, ntabwo bifite ubushobozi bwo kwirinda kuringaniza nka mbere ya QPQ. Impamvu nuko chromium ikubiyemo hejuru yibyuma bitagira ingano byangiritse. Kuberako mugikorwa cyabanjirije QPQ, nikihe buryo bwa nitrodi, karubone na azote bizagenda byinjira, bigatera kwangirika muburyo bwo hejuru. Biroroshye kubora, umunyu utera abakene bizagenda gusa mumasaha make. Kubera iyi ntege nke, ibikorwa byayo ni bike.
