Makonda kanasonkhezereka kupinda masinthidwe mbali zokwezera bulaketi

Njira yopangira galvanizing ndiukadaulo wamankhwala apamwamba omwe amavala pamwamba pazitsulo zazitsulo zokhala ndi chitsulo chosanjikiza cha zinki kuti azitha kukongoletsa komanso kupewa dzimbiri. Chophimba ichi ndi electrochemical protective layer yomwe imalepheretsa dzimbiri zachitsulo. Njira yopangira malata imagwiritsa ntchito njira ziwiri: galvanizing yotentha ndi electro-galvanizing.

Kutentha-kuviika galvanizing ndi kuika workpiece mu otentha-kuviika galvanizing kusamba ndi kutentha kwa kutentha kwina (nthawi zambiri 440 mpaka 480 ° C), kotero kuti wosanjikiza nthaka ndi zolimba omangika pamwamba pa workpiece pa kutentha kwambiri. kupanga kutentha-kuviika galvanizing wosanjikiza. Ndiye, kutentha-kuviika kanasonkhezereka wosanjikiza mokwanira olimba pambuyo kuzirala. Hot-dip galvanizing ali ndi ubwino wapamwamba kwambiri, zokolola zambiri, mowa wotsika, phindu lalikulu lachuma, ndi zina zotero, ndipo zimakhala ndi chitetezo pa anode. Pamene ❖ kuyanika kwatha, imatha kugwira ntchito yoteteza; ngati chophimbacho sichikuwonongeka kwambiri, chovalacho chidzawonongeka chifukwa cha electrochemical action, potero kuteteza chitsulo kuti chisawonongeke.

Electro-zinc plating imayika zinc wosanjikiza pamwamba pa chogwirira ntchito kudzera mu electrolysis. Njirayi ndi yoyenera kwa zokutira zoonda, ndipo chophimbacho chimakhala chofanana.

Mapepala a malata amagwiritsidwa ntchito kwambiri pomanga, zipangizo zapakhomo, mipando, zoyendera, zitsulo ndi zina zofunika tsiku ndi tsiku. Mwachitsanzo, m'makampani omanga, mapepala opangira malata amagwiritsidwa ntchito padenga, mapanelo a khonde, mawindo a zenera, malo osungiramo katundu, misewu yayikulu, ndi zina zotero; m'makampani opanga zida zapanyumba, mapepala opangira malata amagwiritsidwa ntchito mufiriji, makina ochapira, makabati osinthira, zowongolera mpweya, ndi zina zambiri; m'makampani oyendetsa , madenga agalimoto, zipolopolo zamagalimoto, mapanelo achipinda, zotengera, ndi zina zambiri.

Komabe, njira yopangira malata ilinso ndi zovuta zina. Mwachitsanzo, zokutira zamagalasi zimatha kuonongeka ndi kuvala kwa makina, dzimbiri, kapena zinthu zina, kuchepetsa mphamvu yake yodziteteza ku dzimbiri. M'malo otentha kwambiri, zokutira zamagalasi zimatha kulephera chifukwa zinki imakhala ndi malo otsika osungunuka ndipo imatha kusungunuka, kusungunuka, kapena kutaya mphamvu yake yoteteza pakutentha kwambiri. Kuphatikiza apo, kupanga ndi kukonza zokutira zamagalasi kumawononga mphamvu ndi madzi ambiri, motero kumayambitsa zovuta zina zachilengedwe. Panthawi yopangira ndi kukonza, mpweya woyipa ndi madzi oyipa amathanso kupangidwa, zomwe zingakhudze thanzi la munthu.

Kawirikawiri, njira yopangira galvanizing ndi njira yofunika kwambiri yachitsulo yotsutsana ndi dzimbiri yokhala ndi ntchito zambiri. Komabe, pakugwiritsa ntchito, ndikofunikiranso kuganizira zofooka zomwe zingatheke ndikuchitapo kanthu kuti muchepetse zotsatira zake pa chilengedwe komanso thanzi la anthu.
