Amashanyarazi ashyushye, azwi kandi nka hot-dip galvanizing na hot-dip galvanizing, nuburyo bwiza bwo kurinda ruswa ibyuma, cyane cyane bikoreshwa mubyuma byububiko nibikoresho bitandukanye mubikorwa bitandukanye. Nubuhanga bukoreshwa muburyo bwo kubona igifuniko wibiza ibyuma, ibyuma bitagira umwanda, ibyuma bikozwe mubindi byuma mubyuma bishongeshejwe cyangwa ibivanze. Nuburyo bukoreshwa cyane muburyo bwo kuvura ibyuma bifite imikorere myiza nigiciro kwisi kwisi. Ibicuruzwa bishyushye bishyushye bigira uruhare rutagereranywa kandi bidasubirwaho mugabanya ruswa no kuramba, kuzigama ingufu nibikoresho byibyuma. Muri icyo gihe, ibyuma bisize nabyo ni ibicuruzwa byigihe gito byongerewe agaciro gashyigikiwe kandi bigashyirwa imbere na leta.
Inzira yumusaruro
Gukora no gutunganya igiceri cyicyuma gishobora kugabanywamo intambwe eshatu zingenzi: icya mbere, igiceri cyose cyicyuma cyumuringa kizatoragurwa kugirango gikurweho ingese kandi cyanduze kugirango ubuso bwumuringa wicyuma kibe bwiza kandi busukuye; Nyuma yo gutoragura, igomba guhanagurwa muri chloride ya amonium cyangwa zinc chloride ya zinc chloride cyangwa chloride ya amonium na zlor chloride ivanze nigisubizo cyamazi, hanyuma ikoherezwa mubwogero bushyushye kugirango ikorwe; Igikorwa cyo gusya kirangiye, kirashobora kubikwa no gupakira.

Amateka yiterambere yo gushyushya
Gishyushya bishyushye byavumbuwe hagati yikinyejana cya 18. Yatunganijwe uhereye kumabati ashyushye kandi yinjiye mu kinyejana cya kane. Kugeza ubu, gushyushya-gushiramo imbaraga biracyakoreshwa cyane kandi bifatika mugukumira ruswa.
Mu 1742, Dr. Marouin yakoze igeragezwa ry'ubupayiniya ku bijyanye no gushyushya ibyuma no kubisoma muri Royal College of France.
Mu 1837, Sorier wo mu Bufaransa yasabye ipatanti yo gushyushya amavuta ashyushye kandi atanga igitekerezo cyo gukoresha uburyo bwa selile galvanic mu kurinda ibyuma, ni ukuvuga inzira yo gukumira no gukumira ingese hejuru yicyuma. Muri uwo mwaka, Crawford wo mu Bwongereza yasabye ipatanti yo gufata zinc akoresheje ammonium chloride nka solvent. Ubu buryo bwakurikijwe kugeza ubu nyuma yiterambere ryinshi.
Mu 1931, Sengimir, injeniyeri w’indashyikirwa mu nganda zigezweho za metallurgjiya, yubatse umurongo wa mbere uhoraho w’umuriro w’amashyanyarazi ukomoka ku byuma byifashishwa mu kugabanya hydrogène muri Polonye. Ubu buryo bwatangiwe muri Reta zunzubumwe zamerika kandi umurongo w’inganda zishyushya inganda zitwa Sengimir zubatswe muri Amerika hamwe n’uruganda rwa Maubuge Iron and Steel mu Bufaransa mu 1936-1937, bituma habaho ibihe bishya bikomeza, bihanitse- umuvuduko nubwiza buhebuje bushyushye-dip galvanizing for strip ibyuma.
Mu myaka ya za 1950 na 1960, Amerika, Ubuyapani, Ubwongereza, Ubudage, Ubufaransa, Kanada ndetse n'ibindi bihugu byakurikiranye ibyapa bya aluminiyumu.
Mu ntangiriro ya za 70, Isosiyete ya Betelehemu Iron and Steel Company yahimbye ibikoresho byo gutwikira Al-Zn-Si hamwe n’izina ry’ubucuruzi Galvalume, ifite imbaraga zo kwangirika inshuro 2-6 ziva muri zinc nziza.
Mu myaka ya za 1980, amavuta ashyushye ya zinc-nikel yamenyekanye cyane mu Burayi, Amerika na Ositaraliya, kandi inzira yayo yitwaga Technigalva Kugeza ubu, Zn-Ni-Si-Bi yatunganijwe hashingiwe kuri ibyo, bishobora kubuza cyane Sandelin reaction mugihe cyo gushyushya gishyushye cya silikoni irimo ibyuma.
Mu myaka ya za 90, Ubuyapani Nisin Steel Co., Ltd bwateje imbere ibikoresho bya zinc-aluminium-magnesium hamwe n’izina ry’ubucuruzi rya ZAM, irwanya ruswa ikubye inshuro 18 iy'imyenda gakondo ya zinc, yitwa igisekuru cya kane cya ruswa nyinshi. ibikoresho byo gutwikira.

Ibiranga ibicuruzwa
· Ifite ruswa irwanya ruswa hamwe nigihe kirekire cyo gukora kuruta urupapuro rusanzwe rukonje;
· Gufatanya neza no gusudira;
· Ubuso butandukanye burahari: flake nini, flake nto, nta flake;
· Uburyo butandukanye bwo kuvura bushobora gukoreshwa muri passivation, amavuta, kurangiza, kurengera ibidukikije, nibindi;
Gukoresha ibicuruzwa
Ibicuruzwa bishyushye bishyushye bikoreshwa cyane mubice byinshi. Ibyiza byabo nuko bafite ubuzima burebure bwo kurwanya ruswa kandi bashobora guhuza nibidukikije byinshi. Buri gihe ni uburyo buzwi bwo kurwanya ruswa. Ikoreshwa cyane mu munara w'amashanyarazi, umunara w'itumanaho, gari ya moshi, kurinda umuhanda, itara ryo ku mihanda, ibice byo mu nyanja, kubaka ibyuma byubaka ibyuma, ibikoresho bifasha insimburangingo, inganda zoroheje, n'ibindi.
