Phukusi limodzi lomwe lili ndi 96% zinc mufilimu youma, njira ina yolimbana ndi dzimbiri kupita ku dip yotentha.
Kufotokozera
ZINDN ndi paketi imodzi yopangira malata yomwe ili ndi 96% ya zinc fumbi mufilimu youma ndipo imapereka chitetezo cha cathodic ndi chotchinga chazitsulo zachitsulo.
Ikhoza kugwiritsidwa ntchito ngati njira yapadera yokhayokha kuti ikhale njira yotsutsana ndi zowonongeka ku galvanizing yotentha, koma ngati choyambirira mu dongosolo la duplex kapena dongosolo lazitsulo la ZINDN.
Itha kugwiritsidwa ntchito popopera mankhwala, kupukuta kapena kugubuduza pazitsulo zoyera komanso zaukali mumlengalenga wambiri.
Chitetezo cha Cathodic
Mu corrosion electrochemical, zinki zitsulo ndi zitsulo zimalumikizana wina ndi mzake, ndipo nthaka yomwe ili ndi mphamvu yochepa ya electrode imagwiritsidwa ntchito ngati anode, yomwe imataya ma elekitironi mosalekeza ndipo imawonongeka, ndiko kuti, anode ya nsembe;pamene chitsulo chokhacho chimagwiritsidwa ntchito ngati cathode, chomwe chimangotengera ma electron ndipo sichisintha chokha, kotero chimatetezedwa.
Zinc zomwe zili mu ZINDN galvanizing wosanjikiza zapitirira 95%, ndipo chiyero cha fumbi la zinki chomwe chimagwiritsidwa ntchito ndipamwamba kwambiri mpaka 99.995%.Ngakhale kuti galvanizing wosanjikiza wawonongeka pang'ono, chitsulo pansi pa nthaka wosanjikiza sichidzachita dzimbiri mpaka zinc itatheratu, ndipo panthawiyi, ikhoza kuteteza kufalikira kwa dzimbiri.
Chitetezo chotchinga
Makina apadera amachitidwe amapangitsa kuti ZINDN galvanizing wosanjikiza ikhale yodzisindikiza yokha pakapita nthawi mukatha kugwiritsa ntchito, kupanga chotchinga chowundana, kudzipatula pazifukwa za dzimbiri, ndikuwongolera kwambiri luso lodana ndi dzimbiri.
ZINDN imaphatikiza mikhalidwe ya zinthu ziwiri zotsutsana ndi dzimbiri kukhala imodzi, ndikuphwanya malire a pigment-base chiŵerengero cha zokutira wamba, ndikupeza luso la nthawi yayitali loletsa dzimbiri.
95% nthaka fumbi mu ZINDN galvanizing wosanjikiza filimu youma, dzimbiri kachulukidwe panopa ndi apamwamba kwambiri kuposa ❖ kuyanika nthaka wolemera.
Ndi kuwonjezeka kwa fumbi la zinki mu filimu yowuma yowuma, kachulukidwe kameneka kadzawonjezeka kwambiri, ndipo mphamvu ya electrochemical anti-corrosion idzawonjezeka kwambiri.
Ubwino wa ZINDN
Anti-corrosion kwa nthawi yayitali
Zochita + zodzitchinjiriza zapawiri, kuyesa kutsitsi kwa mchere mpaka maola 4500, kukwanitsa kukwanitsa zaka 25+ za moyo wa anticorrosion.
Kumamatira mwamphamvu
Ukadaulo wopangidwa ndi ma fusion agent adathetsa vuto lomatira la fumbi lalikulu la zinc (> 95%) mufilimu youma.4% misa kachigawo cha maphatikizidwe wothandizira akhoza mwamphamvu chomangira 24 kuwirikiza kulemera kwake kwa nthaka fumbi ndi kupanga chomangira ndi gawo lapansi ndi adhesion mpaka 5Mpa-10Mpa.
Kugwirizana kwabwino
ZINDN ingagwiritsidwe ntchito ngati wosanjikiza umodzi kapena dongosolo la zigawo ziwiri kapena zitatu ndi ZD sealer, topcoat, zinki zasiliva, ndi zina zotero, kuti zikwaniritse zosowa zamakasitomala za anticorrosion kwa nthawi yayitali komanso kukongoletsa kokongola muzochitika zosiyanasiyana zachilengedwe.
Palibe kusweka kapena kugwa komwe kumagwiritsidwa ntchito mu weld
ZINDN idathetsa vuto lamakampani kuti galvanizing wosanjikiza amang'amba mosavuta ndikugwa mu weld, amaonetsetsa kuti ntchitoyo ndi yabwino.
Zosavuta kugwiritsa ntchito
Phukusi limodzi, lingagwiritsidwe ntchito popopera mankhwala, kupukuta kapena kupukuta.Siimamira pansi, sichimalepheretsa mfuti, sichimalepheretsa mpope, ikugwiritsidwa ntchito mosavuta.
Mtengo wogwira
Eco-ochezeka, yotsika mtengo, komanso yosavuta kukhudza kuyerekeza ndi kuviika kotentha ndi kuthirira kotenthetsera.
Kutalikirana pakati pa kukhudza ndi kubwezeretsanso, mtengo wotsika wa anticorrosion wa moyo poyerekeza ndi zokutira zolemera za epoxy zinc.

Madontho amafuta apamtunda ayenera kutsukidwa ndi kupopera pang'onopang'ono kapena burashi yofewa ndi chotsukira chapadera, ndipo zotsalira zonse ziyenera kutsukidwa ndi mfuti yamadzi yatsopano, kapena kuthiridwa ndi sopo, lawi lamoto, ndi zina zambiri, ndikutsuka ndi madzi atsopano mpaka osalowerera ndale.Malo ang'onoang'ono a mafuta amatha kutsukidwa ndi zosungunulira.
Chithandizo chapamwamba
Gwiritsani ntchito zida zophulitsa mchenga kapena zamagetsi ndi zida zamanja kuti muchotse dzimbiri, zotuluka, ndi zosenda pamwamba, makamaka zida za dzimbiri, ndipo zolimba zimasalala ndi kuwotcherera.
Kusakaniza
ZINDN ndi chinthu chimodzi chokha.Pambuyo kutsegula mbiya, ayenera akuyambitsa kwathunthu ndi mphamvu chida.
Kuchepetsa chiŵerengero cha 0-5%;chifukwa cha kusiyana kwa kutentha ndi kupopera kupopera kupopera, kuonjezera kwenikweni kwa woonda kumachokera pazochitika zenizeni.
Kugwiritsa ntchito
Kutsuka ndi kugudubuza: maburashi osataya utoto ndi ma roller cores amalimbikitsidwa, ndipo gwiritsani ntchito njira ya criss-cross kuti muvale mofanana kuti mutsimikizire kulowa bwino, komanso samalani kuti mupewe kugwa komanso kusafanana.
Kupopera mbewu mankhwalawa: mpope wopoperapo mphamvu wa 1:32, ndipo sungani zida zopoperazo zaukhondo.
Mphuno yamtundu wa Z imalimbikitsidwa, sungani kutsitsi m'lifupi mwake pafupifupi 25cm, nozzle ndi perpendicular to workpiece pa 90 ° C, ndi mtunda wa mfuti pafupifupi 30cm.
Amalangiza kupopera ndi 2 zokutira zigawo, Pambuyo pamwamba pa nthawi yoyamba youma, utsi kachiwiri, kubwezera mfuti 2 nthawi, ndi ntchito kwa filimu makulidwe otchulidwa malinga ndi zofunika.
