Ukusetshenziswa kwe-zinc uthuli eGalvanization

Inqubo ye-DACRO ingubuchwepheshe obungamelana nobuntu obungamelana nobuntu obutholwe ngaphambi kweminyaka yamuva. Ukuqina okuhlanganisiwe kuvame phakathi kuka-5 kuye ku-10 μm. Indlela yokulwa nokubutha ifaka ukuvikeleka okuvinjelwe i-electrochemical okuhlinzekwe yi-zinc ku-substrate, umphumela wokushisa we-chromate, ikhava yokuvikela imishini enikezwe amashidi e-zinc, kanye ne-composite chromate combongs, kanye nomphumela we- "anodic" I-Aluminium inhibiting zinc.

Uma kuqhathaniswa ne-electro-galvaning yendabuko, izimbangi ze-zinc-chromate zibonisa ukumelana okuqinile kokugqwala, ukuba nezikhathi eziyi-7 kuye kwezingu-10 ezimelana nezimbobo ezinama-electro-galvanized. Akuhlushwa yi-hydrogen emflittlement, okwenza kube khona ikakhulukazi izingxenye zamandla aphezulu. Ngokwengeziwe, ifaka ukumelana nokushisa okuphezulu (ukubekezelela izinga lokushisa okufika ku-300 ° C).

Inqubo Flow for Zinc-Chromate Coating Technology:

I-Organic Solvent ikhipha amandla → Mechanic Polishing → Ukufafaza → Ukuphrinta okomile → ukomisa (60-80 ° C, 10-30 min)

Ngaphezu kwalokho, lobu buchwepheshe bukhululekile ngokungcola ngesikhathi senqubo yokuhlangana, ukumaka inguquko emlandweni wekwelashwa komhlaba wensimbi. Imelela ubuchwepheshe obunqenqemeni emkhakheni wekwelashwa komhlaba wensimbi emhlabeni wonke namuhla, ikakhulukazi ilungele i-chassis yezimoto nenesithuthuthu, izakhi zenjini, kanye nezinto ezinamandla ezinhlaka ezinhlakeni eziphakeme nezinhlaka ze-tubular. I-coating imibukiso ephezulu, ukunamathela okuphezulu, ukumelana kahle kahle, ukumelana kwesimo sezulu esiphakeme, ukuqina okuphezulu kwamakhemikhali, kanye nezimpawu ezingenamakhemikhali.

Ukuvela kwesixazululo se-DACRO Coating kungumbala wesiliva ogqokile. Isixazululo se-coating, ngemuva kokuvinjwa kwenqubo eshiwo ngenhla futhi sibhakwe cishe ngo-300 ° C. Izikhala eziphakathi kwamashidi e-zinc kanye ne-aluminium nazo zigcwele i-chromate eyinhlanganisela, okuholela ekuhlanganisweni okukhethekile okuvikelekile okuyisiliva okuvikelekile kwe-dacros

Izinzuzo ze-mehendi galvanization

Inqubo ilula ukusebenza, inokusetshenziswa kwamandla okuphansi, ihlinzeka ngokukhanya okuhle komhlaba, futhi kubiza kakhulu ekusebenzeni kwezimboni kuqhathaniswa nokwelashwa kwe-dacro.

Izambatho ze-galvanized zisetshenziswa kuma-fasteners angaphandle ukuze amelane nokugqwala kwesikhathi eside ancike kwizakhiwo ze-anode yomhlatshelo ye-zinc. Ngakho-ke, ukuhlanganiswa kufanele kube ne-zinc eyanele ukuqinisekisa ukuthi ama-fasteners angaphandle anamashumi eminyaka okuvikelwa kokugqwala.

Emsebenzini wesikhathi eside, kungakhathalekile ukuthi uluphi uhlobo lobuchwepheshe obungamelana nobuntu obukhona bokugqwala, ukuncipha kokuvimbela noma ukuncipha kwensimbi kuphazamisa izimo ezidingekayo ekwenzeni inqubo yokugqwala noma ukwehlisa i-electrochemical corrosion inqubo. Izakhiwo ze-zinc powder zikwenza kube yinto ebalulekile yokulwa nokugqwala, okuholela kwisicelo sayo esande sasabalele.

I-China inezinsizakusebenza ezicebile ze-lead-zinc ores. Eminyakeni yamuva nje, ukuthuthukiswa kanye nokusetshenziswa kwe-Zinc Pust Ukulungiselela kanye nobuchwepheshe obuvimbela ukugculisana, kanye nokwakhiwa kwezimbozo zokulwa nokukhulisa ezisindayo kusetshenziswa izinto ezifana nezinto eziphilayo ezifana nezinto eziphilayo ezifana Ukwehliswa kokusetshenziswa kwemithombo engavuselelwa emuva ngenkathi kunikeza ubuchwepheshe obusha bokumelana nokuqina kwezinto zokwakha izicelo zokuvikela.
