Kuganiza Kupyolera mu Ma Gaskets Opangidwa ndi Electrogalvanized: Zoposa Zinc Layer 

Mwamva"electrogalvanized gasket"ndipo anthu ambiri nthawi yomweyo amajambula kukana dzimbiri, sichoncho? Ndipo zedi, ameneyo ndiye dalaivala wamkulu. Koma kunena zoona, ndizosiyana pang'ono kuposa kungomenya zinki. Ndawonapo nthawi zina zomwe zimafunikira, ndiye kuti pulogalamuyo sinachite monga momwe amayembekezera. Si chipolopolo chasiliva, ndikumvetsetsa chifukwa chake komanso komwe imawala ndi mawonekedwe ake, makiyi, kapena makiyi nthawi zina. ndipo nthawi zina, kusinthanitsa ndi zochenjera.

Zowona za Zinc Plating pa Gaskets

Tikamalankhula za electrogalvanized, kapena zambiri, zinc-plated gaskets, tikukamba za zokutira nsembe. Zinc imawononga makamaka kuposa chitsulo chapansi, ndikuchiteteza. Zosavuta m'malingaliro. Koma pochita, makamaka ndi ma gaskets omwe amatha kupanikizika ndi kusuntha, wosanjikiza woondawo uyenera kukhala wolimba mokwanira. Sitikunena za ntchito yotentha yotentha pano; electroplating ndi gawo lochepa kwambiri, lolamulidwa kwambiri. Izi zikutanthauza kuti mtundu wa plating - kutsatira, kufanana, makulidwe - ndikofunikira kwambiri. Zinc wosanjikiza kapena wosamata bwino ndi woipa kwambiri kuposa wosanjikiza konse, chifukwa ukhoza kupanga ma cell a dzimbiri.

Ndikukumbukira gulu la ma flange gaskets opangira madzi. Zodziwika bwino: electrogalvanized. Chilichonse chinalembedwa papepala. Koma patapita miyezi ingapo, tinayamba kuona mizere yofiira yofiirira. Zachidziwikire, nyumba yopumirayo inali ndi zovuta zina ndi mzere wawo wochizira, ndipo kumamatira kwa zinki sikunali kwabwino m'malo ena opumira. Chophimbacho chikasokonezedwa, zitsulo zamkati zinkawonekera, ndipo dzimbiri zinayamba. Ndi chikumbutso chabwino kuti chizindikiro cha "electrogalvanized" ndi ndondomeko, osati chinthu chokha, komanso kuwongolera khalidwe lapamwamba ndilofunika kwambiri. Pazofunikira kwambiri, nthawi zina chinthu chosiyana kapena zokutira zolemera kwambiri ngati zokometsera zamakina kapena zokutira zapadera zimatha kukhala zabwinoko, ngakhale zokwera mtengo.

Ndiye pali hydrogen embrittlement factor, makamaka ndi gaskets apamwamba-mphamvu zitsulo. Sizofala kwambiri ndi zitsulo zofatsa, koma ngati mukuchita ndi makina ochapira olimba kapena mtundu wina wa gasket, hydrogen yomwe imayambitsidwa panthawi ya electroplating ikhoza kukhala mutu weniweni. Mumawotcha pambuyo pake, ndithudi, koma sikuti nthawi zonse 100% amagwira ntchito. Ndawonapo zigawo zikugwedezeka pansi pa katundu zomwe siziyenera kukhala nazo, ndikungoyang'ana kumbuyo kwa kuphika kosakwanira pambuyo pa plating. Ndi chimodzi mwazinthu zomwe simuziganizira mpaka zitakulumani, koma ndizodetsa nkhawa kwambiri pazinthu zina.

Kagwiritsidwe Ntchito ndi Zovuta Zachilengedwe

Ndiye, kumene a electrogalvanized gasket ndiyeneradi? Nthawi zambiri, zimakhala za malo ocheperako kapena owononga pang'ono, makamaka m'nyumba kapena m'malo otetezedwa akunja. Ganizirani za ma plumbing amkati, makina a HVAC, zida zamagalimoto pansi pa hood (kutali ndi kutsitsi kwa msewu), kapena makina apamafakitale omwe amawononga mlengalenga koma simukulimbana ndi kukhudzana ndi mankhwala mwachindunji kapena kumizidwa mosalekeza. Ndi njira yotsika mtengo yogwiritsira ntchito zinthu zambiri zomwe zimafunikira zambiri kuposa chitsulo chopanda kanthu koma osapereka mtengo wazitsulo zosapanga dzimbiri kapena ma alloys achilendo.

Vuto limodzi lodziwika bwino ndikungoganiza kuti "zinc" zonse ndizofanana. Pali chromate yowoneka bwino, chromate yachikasu, chromate passivation yakuda pamwamba pa zinki. Iliyonse imapereka kukongola kosiyana pang'ono ndipo, koposa zonse, kumawonjezera kukana kwa dzimbiri. Chromate yomveka bwino ndiyomwe imagwiritsidwa ntchito nthawi zonse, yopatsa mphamvu. Yellow chromate imapereka chitetezo champhamvu kwambiri ndipo nthawi zambiri imawoneka pamagalimoto kapena mafakitale ovuta kwambiri. Black chromate, chabwino, zomwe nthawi zambiri zimakhala zokometsera, koma zimawonjezera chitetezo. Kungotchula "electrogalvanized" popanda kufotokozera pambuyo pa chithandizo kungayambitse ntchito zosiyanasiyana, ndipo ndipamene kusagwirizana kungachitike pakati pa engineering ndi kugula.

Ganizirani ntchito zamapangidwe. Ngakhale kuti Handan Zitai Fastener Manufacturing Co., Ltd. (mutha kuwapeza pa https://www.zitaifasteners.com) amadziwa bwino ma bolts, ma hoops, ndi zida zomata zachitsulo, ma gaskets nthawi zambiri amathandizira pamisonkhanoyi. Ngati zomangira zazikuluzikulu zili ndi malata otentha kuti ziwonekere panja, kugwiritsa ntchito gasket yopyapyala yopangidwa ndi ma electrogalvanized kungapangitse ulalo wofooka wa unyolo woteteza dzimbiri. Muyenera kuyang'ana dongosolo lonse. Gasket, ngakhale yaying'ono, nthawi zina ikhoza kukhala yoyamba kulephera ngati kukana kwake kwa dzimbiri sikufanana ndi msonkhano wonse. Zimakhudza malingaliro athunthu, osati kungotengera gawo lokhalokha.

Beyond Corrosion: Zolinga zamakina ndi Misonkhano

Sikuti amangoletsa dzimbiri. An electrogalvanized gasket imafunikanso kugwira ntchito ndi makina. Kuchuluka kwa plating, ngakhale kuonda, nthawi zina kumatha kukhudza ma torque kapena kukwanira pakulolera kolimba kwambiri. Kwa ma washer ambiri okhazikika kapena ma gaskets osalala, nthawi zambiri amakhala osafunikira. Koma kwa ma shims olondola kapena ochapira masika, ndikofunikira kuyang'ana kawiri. Kuyikapo pachokha sikuyenera kusintha kwambiri makina azinthu zomwe zili pansi pake, pokhapokha atachita bwino komanso kuchepetsedwa kwa hydrogen. Koma ndi chinthu choyenera kudziwa, makamaka ndi zigawo zogwira ntchito kwambiri.

Msonkhano ndi malo ena omwe zochitika zimakuuzani zambiri. Ngakhale zokutira za zinki zimapereka zokometsera, si mafuta olemetsa. Pazinthu zomwe zimafuna kuwongolera kolondola kwa makokedwe, makamaka ndi mabawuti akulu kapena zolemetsa zazikulu, mungafunikebe mafuta owonjezera pa ulusi kapena pansi pa mutu wa bawuti, mosasamala kanthu za kutha kwa gasket. Osadalira zokutira za zinki zokha kuti muwonetsetse kuti torque imakhazikika. Tawona kulephera kokwanira kogwirizana kuti tidziwe kuti kudula njira pamisonkhano, ngakhale ndi zigawo zooneka ngati zotetezedwa bwino, ndi chuma chabodza.

Pomaliza, yosungirako. Zingamveke ngati zofunikira, koma ngakhale electrogalvanized gasket, ngati itasungidwa molakwika m'malo a chinyontho kapena kutsekedwa ndi condensation, ikhoza kukhala ndi "dzimbiri loyera" - powdery zinc oxide / hydroxide. Sikumapeto kwa dziko lapansi pazogwiritsa ntchito zambiri, koma zikuwoneka zoyipa ndipo zimatha kuwonetsa kusanjikiza kotetezedwa. Kusungirako koyenera, kutali ndi chinyezi chachindunji, kumapangitsa kusiyana pakuwonetsetsa kuti magawo omwe mumakoka kuti asonkhanitse akadali bwino. Handan Zitai Fastener Manufacturing Co., Ltd., monga katswiri wofalitsa wamkulu, amamvetsetsa kufunikira kwa zinthu zothandiza izi zamtundu wazinthu ndi kasamalidwe, ndikuwonetsetsa kuti zinthu zawo zikukwaniritsa zomwe amayembekeza kuchokera kumalo osungiramo katundu mpaka kukhazikitsidwa komaliza.
