Ihame ryo gutera zinc mu buryo bushyushye rishobora kuvugwa muri make ku buryo bukurikira: icya mbere, umwuka n'imiyoboro bikoresha umuvuduko mwinshi bikoreshwa mu gutera utuntu tw'umucanga ku buso bw'igikoresho kugira ngo bikureho ingese n'ubunini bwa okiside ku buso bw'icyuma, mu gihe ubuso budafite imbaraga zo kongera ubushobozi bwo gutera zinc mu buryo bushyushye. Hanyuma, ogisijeni, acetylene cyangwa isoko y'ubushyuhe bw'amashanyarazi (ubushyuhe bw'amashanyarazi bukoreshwa ku bikoresho binini, ogisijeni na acetylene bikoreshwa ku bikoresho bito n'ibiciriritse) bikoreshwa binyuze mu mwuka ufunze kandi ibikoresho byihariye (imbunda zikoresha umuvuduko mwinshi) bikoreshwa mu gutera zinc mu buryo bwa atome ku buso bw'icyuma ku muvuduko mwinshi cyane.
Ibyiza byo Gutera Ingufu
1. Gutera ibyuma bikonjesha bikoresha uburyo bwo gusiga ibishishwa mu gukaraba no gusiga fosfeti mu buryo bwo kuvura mbere, bigasiga ibisigazwa bya aside na alkali ku buso bw'ibikoresho, bigatera ibyago byo kwangirika no gutuma igishishwa cya zinc gikonjesha gishobora kwangirika. Uburyo bwo gutera zinc bukoresha uburyo bwo gutera umucanga mu buryo bwo kuvura mbere, bigatuma ubuso bw'ibikoresho busukuye kandi bugoye. Ibi birinda kwangirika imbere no kwangirika nyuma yo gutera zinc.
2. Gukoresha galvanizing ishyushye bisaba ubushyuhe bwihariye bwa dogere selisiyusi 440, bishobora gutera guhindagurika kw'icyuma gikoreshwa. Ariko, uburyo bwo gutera zinc bukoresha ubushyuhe buri hasi cyane, munsi ya dogere selisiyusi 80, bikarinda guhindagurika. 3. Uburyo bwo gutera zinc ishyushye n'ikoreshwa mu gutera zinc igabanya uburebure, ubugari, n'uburebure bw'ikigega gitera zinc, mu gihe uburyo bwo gutera zinc butari bwo.
4. Uburyo bwo gukaraba ibyuma bikonjesha n'ibishyushye nabyo bitera imbogamizi yo gusana aho hantu. Kwangirika kw'ibikoresho byo gusudira mu gihe cyo gushyiraho, gupakira no gupakurura aho hantu, cyangwa gutwara bishobora gusanwa hakoreshejwe irangi gusa. Hamwe no gutera zinc, gusana aho hantu bishobora gukorwa hakoreshejwe gutera zinc, hirindwa ingorane zo gukora.
5. Kubera ko gukoresha galvanizing mu buryo bukonje bikoresha pickling na phosphating mbere yo kuvura, ubuso bw'aho bakorera ni bubi kandi icyuma gifata neza. Mu buryo bunyuranye, gutera zinc bikoresha sandblasting mbere yo kuvura, bigatuma icyuma gifata neza kandi gifata neza, gifite imbaraga zo gukurura za ≥6 MPa.
6. Gukoresha galvanizing mu mazi ashyushye bihumanya cyane amazi kandi bigatera ibibazo bikomeye ku bidukikije, mu gihe gukoresha galvanizing mu mazi ashyushye bitera ingaruka nke ku bidukikije. Kubwibyo, gukoresha galvanizing mu mazi ashyushye bizarushaho gukundwa mu kurinda ingese ku nyubako z'ibyuma.
Uburyo bwo gutera Zinc ishyushye
Uburyo bwose bwo kubaka zinc ishyushye irwanya ingese bugabanyijemo intambwe enye: gutunganya ubuso → gutera zinc → gutunganya zinc → kugenzura ubuziranenge
Ubuvuzi bw'ubuso
Kubera ko ubwiza bw'ubuso bugira ingaruka zitaziguye ku bwiza no ku kuramba kw'igitambaro, gutunganya neza ubuso bw'ibanze ni ngombwa. Gutera umusenyi ku buso bw'ibanze kugira ngo ukureho ingese hakurikijwe ibisabwa mu buryo. Amabwiriza yo gukuraho ingese akurikiza amahame ya Sa3 mu "Ingano z'ingese n'Ingano zo gukuraho ingese ku buso bw'icyuma mbere yo gusiga irangi" (GB8923-88). Iri tegeko risobanura ibisabwa ku bwiza bukurikira: Gutera umusenyi neza kugira ngo ukureho igitambaro, amavuta, ingese, umwanda, irangi, n'ibindi bifatanye. Ubuso bugomba kugaragaza ubwiza bw'icyuma bungana. Nyuma yo gutera umusenyi, sukura ubuso ukoresheje umwuka mwiza kandi wumye cyangwa uburoso bwiza. Amabwiriza ya Sa3 mu "Ingano z'ingese n'Ingano zo gukuraho ingese ku buso bw'icyuma mbere yo gusiga irangi" (GB8923-88) na yo agomba kwitabwaho.
Guturika umucanga
Mu gihe cyo gukoresha, hakoreshwa ibikoresho n'ibipimo bikurikira: icyuma gikonjesha umwuka, ikigega cy'umwuka, igice gitandukanya amazi n'amavuta, akayunguruzo k'umwuka, isafuriya yo guturika umucanga, kaseti ifata, imbunda yo guturika umucanga, n'umusenyi wa porcelain udashira. Umusenyi ufata umucanga wo mu ruzi ukomera cyane, ufite umusenyi wo mu ruzi (0.5-2mm). Umusenyi ugomba kuba wumutse, ufite ubushuhe buri munsi ya 1%, kandi usukuye kandi udafite umwanda. Akayunguruzo gakoresha umusenyi wa porcelain ufite ishusho ya L. Binyuze mu cyiciro cyo kwagura no gukanda, umwuka uva mu musenyi utera umuvuduko ukabije, wongera cyane ingufu z'umusenyi, ukongera gukora no gutanga amashanyarazi ku buso bwa substrate, bityo wongera imbaraga zo gufatanya. Uburyo bwo gukuraho ingese burimo umwuka ukandagiye winjira mu kigega cy'umwuka, unyuze mu gikoresho gitandukanya amazi n'amavuta n'akayunguruzo k'umwuka kugira ngo ube mwiza, wumuke, kandi utagira amavuta, mbere yo kwinjira mu gikoresho gitera umucanga. Kaseti ifata umusenyi mu mbunda yo guturika umucanga hanyuma ikawutera ku cyuma. Hakoreshejwe ibi bikoresho n'imiterere yabyo, gutunganya ubuso bishobora kuzuza amahame ya Sa3, hamwe n'ubukana bw'ubuso bwa 40-60µm. Kuri iyi ngingo, ubushobozi bwa electrode, urwego rwo gukora, hamwe no gufatana kw'ubuso bw'icyuma byose byageze ku bipimo byiza.
Gutera Zinc
Gutera zinc bigomba kurangira mu masaha 2-3 nyuma yo gutera umucanga. Ibi biterwa nuko ubushobozi bwa electrode y'ubuso bw'umucanga nyuma yo gutera umucanga butandukanye cyane n'ubwo mbere yo kuvurwa, bigatuma igera ku bushobozi bwayo bwo hasi. Kuri iyi ngingo, gukora k'ubuso bw'umucanga kugera ku gaciro kayo ntarengwa, kandi imbaraga zo gufatanya hagati y'umucanga n'igitambaro ziba ziri hejuru cyane. Ubushobozi bwa electrode ku buso bw'umucanga buguma buhamye mu gihe cy'amasaha 2-3. Uko igihe kigenda gihita, ubushobozi bwa electrode ku buso butangira kwiyongera, imbaraga zo gukorana ziragabanuka, kandi imbaraga zo gufatanya hagati y'igitambaro n'igitambaro ziragabanuka. Ibi biterwa n'ubunini bwa oxide film yo hejuru. Mu masaha 2-3, oxide film yoroshye ivunika byoroshye n'uduce duto two guteranya twihuta iyo tugize ingaruka ku buso. Nyuma y'amasaha 2-3, oxide film ikora nk'uruzitiro hagati y'igitambaro n'igitambaro, bigahungabanya uburyo igitambaro n'igitambaro bifatanye. Ibikoresho byo guteranya bikoresha spray gun ikorerwa mu gihugu (ubusanzwe ikoreshwa mu buryo bw'umwuka bwa Zhonglian spray gun ituruka mu ruganda rwa Shanghai Spraying Machinery Factory). Ibikoresho bya zinc bikoreshwa ni insinga ya zinc nziza kandi idafite amavuta ifite umurambararo wa mm 3 n'ingano ya zinc iri hagati ya 99.5% na 99.7%.
