Byoherejwe 2019-04-29Tekinoroji ya Dacromet ifite urukurikirane rwibyiza isahani gakondo idashobora guhura, kandi ihita itera isoko mpuzamahanga.Nyuma yimyaka irenga 20 yiterambere ryiterambere no gutera imbere, tekinoroji ya Dacromet ubu yashyizeho uburyo bwuzuye bwo kuvura hejuru, bukoreshwa cyane mukurwanya ruswa yibice byibyuma.
Ibintu nyamukuru biranga chrome-idafite icyatsi kibisi
Umubyimba: 1. Ubunini bwikibiriti ni microne 6-12, naho ubunini bwikibiriti hamwe nuburinganire bwa microne 10-15.2, anaerobic gucikamo ibice: kuvura gutwika ntibisaba gutoragura cyangwa kubisahani.3. Kurandura iterabwoba ryangirika ryibyuma bibiri: Isasu rikuraho ruswa ya bimetallic ya zinc-aluminium cyangwa zinc-fer ikunze kugaragara muri coinc zinc.4. Kurwanya umusemburo: Ipfunyika idafite imbaraga zifite imbaraga zo guhangana na solvent.5, kurwanya ubushyuhe: igifuniko kirimo umubare munini wibyuma, bishobora gutwara amashanyarazi.6, Kurwanya ruswa Imikorere: ikizamini cyo gutera umunyu amasaha 240-1200 amasaha 8, imikorere ya adhesion: iruta zinc chromium (Dacro coating).
Imikorere myiza y’ibidukikije: 1, nta chromium: ntabwo irimo ubwoko bwa chromium (harimo trivalent na hexavalent) 2, ntabwo irimo ibyuma byuburozi: ntabwo irimo nikel, kadmium, gurş, antimoni na mercure.
Inzira ya Chrome idafite icyatsi kibisi irwanya ruswa
Ingaruka yo gukingira: 1. Ifu ya scinc zinc-aluminium itunganya neza kwinjira mubitangazamakuru byangirika.2, yin na yang kurinda: zinc nkigitambo cya anode kugirango urinde icyuma kwangirika.3. Passivation: Okiside ya metal itinda kwangirika kwa bimetallic ya zinc na fer substrate.4, kwikiza: ogisijeni na karuboni ya dioxyde de carbone mu kirere ikora hamwe na zinc hejuru yikibiriti kugirango ikore zinc oxyde na karubone ya zinc.Kubera ko ingano ya okiside ya zinc na karubone ya zinc ari nini kurenza urugero rwa zinc, iyo yimukiye ahantu yangiritse, irashobora Ku ngaruka zo gusana.
