Kodi mitengo ya m'misewu ya dzuwa iyenera kuikidwa magalavu ozizira kapena magalavu otentha?

Masiku ano, ma coil achitsulo apamwamba a Q235 ndi omwe amagwiritsidwa ntchito kwambiri popanga zinthu.ndodo za mumsewu za dzuwaPopeza magetsi a mumsewu okhala ndi mphamvu ya dzuwa amawotchedwa ndi mphepo, dzuwa, ndi mvula, moyo wawo wautali umadalira mphamvu zawo zopirira dzimbiri. Chitsulo nthawi zambiri chimayikidwa ndi galvanized kuti izi zitheke.

Pali mitundu iwiri ya zinc plating: hot-dip ndi cold-dip galvanizing.ndodo zachitsulo zotenthedwa ndi madzi otenthaZimakhala zolimbana ndi dzimbiri, nthawi zambiri timalangiza kuti tizigule. Kodi kusiyana pakati pa galvanizing yothira madzi otentha ndi yothira madzi ozizira ndi kotani, ndipo n’chifukwa chiyani matabwa othira madzi otentha amakhala olimba kwambiri? Tiyeni tiwone Tianxiang, fakitale yotchuka ya mitengo ya m’misewu ku China.

1) Kukonza Madzi Ozizira (Kumatchedwanso electro-galvanizing): Pambuyo pochotsa mafuta ndi kusakaniza, chitsulocho chimayikidwa mu yankho la mchere wa zinc. Yankholo limalumikizidwa ku electrode yoyipa ya zida za electrolysis, ndipo mbale ya zinc imayikidwa moyang'anizana, yolumikizidwa ku electrode yoyipa. Mphamvu ikayatsidwa, pamene mphamvu ikuyenda kuchokera ku electrode yoyipa kupita ku electrode yoyipa, gawo lofanana, lokhuthala, komanso logwirizana bwino la zinc limapangidwa pamwamba pa chitoliro chachitsulo.

2) Kuthira galvanizing m'madzi otentha: Pamwamba pa chitsulocho pamadzimira mu zinc yosungunuka pambuyo poyeretsa ndi kuyatsa. Zinc yachitsulo imapangika pamwamba pa chitsulo chifukwa cha kusintha kwa fizikiki pakati pa chitsulo ndi zinc pamalo olumikizirana. Poyerekeza ndi kuzizira, njira iyi imapanga mgwirizano wolimba pakati pa chophimbacho ndi substrate, zomwe zimapangitsa kuti chivundikirocho chikhale cholimba, kulimba, kugwira ntchito popanda kukonza, komanso kugwiritsa ntchito ndalama zochepa.

1) Njira Yopangira: Mayina awo amafotokoza bwino kusiyana kwake. Zinc yomwe imapezeka kutentha kwa chipinda imagwiritsidwa ntchito m'mapaipi achitsulo opangidwa ndi galvanized ozizira, pomwe zinc yomwe imapezeka pa 450°C mpaka 480°C imagwiritsidwa ntchito mu galvanization yotenthedwa.

2) Kukhuthala kwa Chophimba: Ngakhale kuti chophimba chozizira nthawi zambiri chimapanga makulidwe a 3–5 μm okha, zomwe zimapangitsa kuti ntchito ikhale yosavuta, sichimalimbana ndi dzimbiri. Mosiyana ndi zimenezi, chophimba chotentha nthawi zambiri chimapereka makulidwe a 10μm kapena kuposerapo, omwe ndi olimba kwambiri kuposa ndodo zowunikira zozizira.

3) Kapangidwe ka Kuphimba: Chophimbacho ndi gawo lapansi zimalekanitsidwa ndi wosanjikiza wofooka kwambiri mu chovindikira chotentha. Komabe, chifukwa chophimbacho chimapangidwa ndi zinc yokha, zomwe zimapangitsa kuti chikhale chofanana ndi ma pores ochepa, zomwe zimapangitsa kuti chisawonongeke kwambiri, izi sizikhudza kwambiri kukana kwake ku dzimbiri. Mosiyana ndi zimenezi, chovindikira chozizira chimagwiritsa ntchito chovindikira chopangidwa ndi maatomu a zinc ndi njira yolumikizirana ndi ma pores ambiri, zomwe zimapangitsa kuti chiziwopsezedwa ndi dzimbiri.

4) Kusiyana kwa Mitengo: Kupanga ma galvanizing otenthedwa ndi madzi kumakhala kovuta komanso kovuta. Chifukwa chake, makampani ang'onoang'ono omwe ali ndi zida zakale nthawi zambiri amagwiritsa ntchito ma galvanizing otenthedwa ndi madzi ozizira, zomwe zimapangitsa kuti ndalama zichepe kwambiri. Opanga ma galvanizing akuluakulu komanso odziwika bwino nthawi zambiri amakhala ndi kuwongolera bwino khalidwe, zomwe zimapangitsa kuti ndalama zikwere.

Anthu ena anganene kuti ngakhale atadziwa kusiyana pakati pa kugayira chitsulo chozizira ndi kugayira chitsulo chotentha, sangathebe kuzindikira kusiyana. Izi ndi njira zopangira zomwe sizikuwoneka ndi maso. Nanga bwanji ngati wamalonda wosakhulupirika akugwiritsa ntchito kugayira chitsulo chozizira m'malo mwa kugayira chitsulo chotentha? Ndipotu, palibe chifukwa chodera nkhawa. Kugayira chitsulo chozizira ndichotenthetsera madzi otenthan'zosavuta kusiyanitsa.

Malo opangidwa ndi ma galvanized ozizira amakhala osalala, makamaka achikasu-obiriwira, koma ena akhoza kukhala ndi kuwala kowala, koyera-buluu, kapena koyera kobiriwira. Angawoneke ngati opanda kuwala kapena odetsedwa. Malo opangidwa ndi ma galvanized otentha, poyerekeza, ndi okhwima pang'ono, ndipo amatha kukhala ndi maluwa a zinc, koma amawoneka owala kwambiri ndipo nthawi zambiri amakhala oyera ngati siliva. Samalani kusiyana kumeneku.
