Icyuma cya galvanised ibyuma ni umutwaro uremereye - ufite ibikoresho bihuza imirongo yohereza hejuru hamwe nuburyo bwo gusimbuza. Zifite cyane cyane ibikorwa byingenzi nko kwimura imizigo, guhagarika insulirasi, no kuyobora neza. Imiterere yubukanishi, uburinganire buringaniye, kurwanya ruswa, hamwe nuburinganire bwimiterere bigena neza umutekano wumurongo. Ashyushye - dip galvanizing ntabwo itanga gusa urupapuro rwakazi hamwe nuburinzi bubiri - gukingira umubiri no kurinda catodiki - ariko kandi bigira ingaruka zikomeye kubutaka bwibyuma, kuburinganire bwukuri, kumiterere yubutaka, hamwe nubukanishi mugihe cyo hejuru - kwibiza ubushyuhe, uburyo bwo gukonjesha imiti, hamwe nuburyo bukonje bwihuse. Izi ngaruka zizamura cyane cyane imikorere myiza yicyuma cyogosha icyuma.
Nkumutwaro - bikwiranye, ibintu byingenzi byubukanishi bwibikoresho byicyuma byingufu ni imbaraga zingutu, imbaraga zitanga umusaruro, kuramba, gukomera gukomera, no gukomera. Ibikoresho bisanzwe birimo Q235B, Q355B, ASTM A36, na A572 Gr50, byose bikaba biri hasi - ibyuma byubaka. Ubushyuhe - dip ubushyuhe bwa dogere ni dogere 440-460, munsi yubushyuhe bwa reystallisation yicyuma, bityo ntibitera kugabanuka gukomeye kwingufu zifatizo. Imbaraga zingana zitandukanye mubisanzwe<5%, generally maintaining factory-set levels. Yield strength fluctuates slightly but remains generally stable. Due to the high-temperature tempering effect, internal stress is slightly released, and plasticity is slightly improved. Short-term high-temperature holding causes a slight decrease in surface hardness, which does not affect the overall load-bearing capacity.
Ibyuma byometseho ibyuma bifite ibyangombwa bisabwa cyane kugirango umwobo wa diameter, intera y'umwobo, uburinganire, perpendicularity, hamwe nubunini muri rusange. Ashyushye - kwibiza ni inzira nyamukuru itera gutandukana kurwego, hamwe nibintu birimo umubyimba wa zinc, ihindagurika ryumuriro, hamwe no kugabanuka gukonje. Mugihe cyo gukora, ibyo dusabwa mubisanzwe mubyimbye bya plaque ni impuzandengo ya zinc igizwe nubunini burenze cyangwa bungana na 86 μm kubisahani Birenze cyangwa bingana na 6mm, hamwe nuburinganire bwaho bugera kuri 100-120 mm. Ubwiyongere bw'urwego bugera kuri 0.08–0.12mm kuri buri ruhande, hamwe no kwiyongera muri rusange Kurenza cyangwa kungana na 0.24mm. Mubyihanganirwa byemewe, diameter yumwobo igabanukaho 0.16–0.24mm, bigira ingaruka nke kubiterane bisanzwe. Bitewe na zinc layer imwe ifatanye, umwanya wimyanya hagati yumwobo ntigihinduka cyane, hamwe no gutandukana Ntibisanzwe cyangwa bingana na 0.1mm.
Ashyushye - dip galvanizing igena neza nubuso bwimiterere yibibaho byicyuma, bigira ingaruka kumiterere, neza, zinc nodules, na burrs. Ikora ifeza imwe - ibara ryijimye rya zinc, bivamo isura nziza ihoraho, itwikiriye ibimenyetso byo gutunganya, gushushanya bito, hamwe na okiside, byujuje ubuziranenge bwibicuruzwa byoherezwa mu mahanga, kugabanya ingese zera, no gukora ubuso bwera.
Ibyuma byogosha ibyuma byateguwe mugihe cyimyaka 20-30. Kurwanya ruswa nikimenyetso cyibanze, kandi ashyushye - dip galvanizing ninzira ifatika yo kunoza ruswa; nta bundi buryo. Uburyo bubiri bwo kurinda ruswa, hamwe nuburinganire bwa zinc, butandukanya itangazamakuru ryangirika nka H₂O, O₂, Cl⁻, na SO₂, hamwe na zinc bikunda kwangirika, kurinda ibyuma byangiza ingese. Nyuma yubushyuhe - kwibiza, isahani yingogo irashobora kwihanganira ibidukikije bisanzwe byikirere, ibidukikije byangiza umunyu winyanja, ibidukikije byimvura ya acide yinganda, hamwe nubushuhe bwinshi hamwe na UV yo hanze.
Imirongo yohereza ikorerwa kunyeganyega umuyaga, imitwaro yikonje, guhangayikishwa nubushyuhe, hamwe no kunyeganyega kwabayobora mugihe kirekire. Isahani ihuza ikenera umunaniro mwiza cyane, kandi ishyushye - dip galvanizing igira ingaruka zikomeye kuri ibi. Ashyushye - dip galvanizing ikuraho imihangayiko yimbere yo gutunganya, igabanya amahirwe yo gutangizwa numunaniro, ikabuza kwangirika kwangirika, ikarinda gutera - iterwa numunaniro ukabije, igahindura microstructure, kandi ikemeza ko nta gihinduka kigaragara mugihe kirekire -.
Ashyushye - kwibiza ntibishobora kubangamira umutwaro wubatswe - byerekana imikorere yicyuma gisya; Ibinyuranye naryo, itezimbere cyane kurwanya ruswa no kwizerwa mu mikorere, bigatuma iba inzira yingenzi yo kwemeza agaciro k'ibicuruzwa.
