Njira yolamulidwa, yomwe imayendetsedwa ndi makina ochokera kwa opanga zida zapamwamba kwambiri zopaka ma galvanizing, imakhudza mwachindunji makulidwe omaliza a chophimba. Kukhuthala kumeneku ndi chizindikiro chofunikira cha moyo wa ntchito ya chitsulo. Chophimba cha zinc chokhuthala komanso chofanana chimapereka nthawi yayitali yotetezera komanso kuteteza kudzipereka. Miyezo yamakampani imatchula makulidwe ochepa a chophimba kutengera mtundu ndi kukula kwa chitsulocho, ndikuwonetsetsa kuti chitha kupirira malo omwe chikufunidwa kwa zaka zambiri popanda kukonza kwambiri.
HDG vs. Njira Zina: Kuyerekeza kwa Magwiridwe Antchito a 2025
Kusankha njira yotetezera dzimbiri kumafuna kuyang'anitsitsa bwino momwe imagwirira ntchito, kulimba, komanso mtengo wake kwa nthawi yayitali. Ngakhale pali njira zina zambiri,chotenthetsera madzi otenthanthawi zonse imatsimikizira kuti ndi yabwino kwambiri poyerekeza ndi utoto, ma epoxies, ndi ma primer.
Zophimba Zotsutsana ndi Utoto ndi Epoxy
Zophimba utoto ndi epoxy ndi mafilimu apamwamba. Zimapanga gawo loteteza koma sizimalumikizana ndi chitsulo. Kusiyana kwakukulu kumeneku kumabweretsa mipata yayikulu yogwirira ntchito.
Zophimba za epoxy zimakhala zosavuta kulephera. Zingathe kusweka ndi kusweka, zomwe zimawonetsa chitsulo chomwe chili pansi pake. Chotchinga chikasweka, dzimbiri limatha kufalikira mofulumira. Bungwe la New York State Thruway Authority linaphunzira izi paokha. Poyamba ankagwiritsa ntchito rebar yokhala ndi epoxy-coated rebar pokonza misewu, koma zophimbazo zinasweka mwachangu. Izi zinapangitsa kuti misewu iwonongeke mofulumira. Atasintha kugwiritsa ntchito galvanized rebar pokonza mlatho, zotsatira zake zinali zodabwitsa kwambiri kotero kuti tsopano akugwiritsa ntchito zipangizo zophimba galvanized pa ntchito zawo.
Zofooka za zokutira za epoxy zimamveka bwino poyerekeza ndi HDG.
Zigawo za aloyi zolimba kwambiri zimalimbana ndi kusweka ndi kugwedezeka.
Kukonza
Palibe kuthekera kodzikonzera wekha. Malo owonongeka ayenera kukonzedwa ndi manja.
Zimateteza malo ang'onoang'ono owonongeka kudzera mu zochita zodzipereka.
Kugwiritsa ntchito ndi kusunga zinthu kumabweretsanso mavuto akuluakulu pa zophimba za epoxy.
Chiwopsezo cha Kuwonongeka: Epoxy ndi yofooka. Kukanda ponyamula kapena kuyika kungapangitse kuti dzimbiri liziyenda.
Kuzindikira kwa UVChitsulo chophimbidwa ndi epoxy chimafuna ma tarps apadera osungira panja. Chiyenera kukhala chophimbidwa kuti chisawonongeke ndi dzuwa.
Kutayika kwa Kumatira: Chigwirizano cha chophimbacho ndi chitsulocho chingafooke pakapita nthawi, ngakhale chikasungidwa.
Malo Ozungulira Nyanja: M'madera a m'mphepete mwa nyanja, zokutira za epoxy zimatha kugwira ntchito moyipa kuposa chitsulo chopanda kanthu. Mchere ndi chinyezi zimachotsa mosavuta vuto lililonse laling'ono lomwe lili mu zokutirazo.
M'malo okhala ndi gombe, HDG imasonyeza kulimba kwake. Ngakhale m'malo omwe muli mphepo yamchere, chitsulo chopangidwa ndi galvanized chingathe kukhala zaka 5-7 chisanayambe kukonzedwa. Malo otetezedwa omwe ali pamalo omwewo akhoza kutetezedwa kwa zaka zina 15-25.
Zoyambira Zolemera ndi Zinc
Ma primer okhala ndi zinc nthawi zambiri amaperekedwa ngati njira ina yamadzimadzi m'malo mwa galvanizing. Ma primer awa ali ndi fumbi la zinc lochuluka lomwe limasakanizidwa mu cholumikizira utoto. Tinthu ta zinc timapereka chitetezo chodzipereka, koma dongosololi limadalira mgwirizano wamakina, mofanana ndi utoto wamba.
Mosiyana ndi zimenezi, kupopera kwa galvanizing kotentha kumapanga zigawo zake zoteteza kudzera mu kufalikira kwa kutentha kwambiri. Izi zimapanga zitsulo zenizeni za zinc-iron zomwe zimagwirizanitsidwa ndi chitsulo. Choyambira chokhala ndi zinc chochuluka chimangomamatira pamwamba. Kusiyana kumeneku kwa mgwirizano ndi chinsinsi cha magwiridwe antchito abwino a HDG.
Mbali
Kuviika mu Dip Yotentha
Primer Yolemera ndi Zinc
Njira
Chigwirizano cha zitsulo chimapanga zigawo zolimba za zinc-iron alloy.
Fumbi la zinki mu chogwirira ntchito limapereka chitetezo chodzipereka.
Kumatira
Yolumikizidwa ku chitsulo ndi mphamvu yolumikizira ya ~3,600 psi.
Kugwirizana kwa makina kumadalira ukhondo wa pamwamba; kufooka kwambiri.
Kulimba
Zigawo zolimba kwambiri za aloyi zimalimbana ndi kusweka ndi kugwedezeka.
Ngakhale kuti ma primer okhala ndi zinc ambiri amapereka chitetezo chabwino, sangafanane ndi kulimba komanso kukhalitsa kwa utoto weniweni wa galvanized. Kugwira ntchito bwino kwa primer kumadalira kukonzekera bwino ndi kugwiritsa ntchito pamwamba, ndipo kumakhalabe pachiwopsezo cha kukanda ndi kuwonongeka kwakuthupi.
Kuthetsa Kutsutsa Kofala kwa HDG
Lingaliro lolakwika lofala pankhani ya galvanizing yotenthedwa ndi mtengo wake woyamba. Kale, HDG nthawi zina inkaonedwa ngati njira yokwera mtengo kwambiri poyamba. Komabe, sizili choncho mu 2025.
Chifukwa cha mitengo yokhazikika ya zinc komanso njira zogwirira ntchito bwino, HDG tsopano ndi yopikisana kwambiri pamtengo woyamba. Poganizira mtengo wonse wa moyo wonse, HDG nthawi zambiri imakhala chisankho chotsika mtengo kwambiri. Machitidwe ena amafunika kukonza ndikugwiritsanso ntchito pafupipafupi, zomwe zimapangitsa kuti pakhale ndalama zambiri pa moyo wonse wa polojekitiyi.
Bungwe la American Galvanizers Association limapereka Chowerengera Mtengo wa Moyo (LCCC) chomwe chimayerekeza HDG ndi machitidwe ena opitilira 30. Detayo imasonyeza nthawi zonse kuti HDG imasunga ndalama. Mwachitsanzo, mu kafukufuku wina wa mlatho wokhala ndi moyo wa zaka 75 wopangidwa:
Kuviika mu Dip Yotenthaanali ndi mtengo wokwera wa moyo wonse$4.29 pa sikweya mita.
AnEpoxy/Polyurethanedongosololi linali ndi mtengo wa moyo wonse wa$61.63 pa sikweya mita.
Kusiyana kwakukulu kumeneku kumachokera ku magwiridwe antchito a HDG osakonza. Kapangidwe ka galvanized nthawi zambiri kamakhala zaka 75 kapena kuposerapo popanda kufunikira ntchito yaikulu. Izi zimapangitsa kuti ikhale ndalama yanzeru kwambiri yogwiritsira ntchito mapulojekiti a nthawi yayitali.
