Kodi opanga zinc alloy die-casting amathetsa bwanji thovu la mpweya?

Zinc alloy ndi aloyi wopangidwa ndi zinc wophatikizidwa ndi zinthu zina. Zinc alloys ndi osavuta kupanga, amakhala ndi pulasitiki wolimba, mtengo wotsika, magwiridwe antchito apamwamba, komanso magwiridwe antchito osiyanasiyana. Komabe, zovuta zotulutsa thovu (electroplating ndi kupopera) kwa Jiangmen zinc alloy die castings ndizovuta zina. Ndiye mungathetse bwanji chifukwa cha matuza? Mfundo zotsatirazi:

1. Kapangidwe kazinthu

Pamene mapangidwe a zinc alloy die-casting-casting ayamba, m'pofunika kuganizira malo odyetserako chakudya, doko lotulutsa slag ndi kutulutsa mpweya wa nkhungu yoponyera kufa. Chifukwa otaya njira workpiece kudyetsa ndi slagging ndi yosalala, palibe mpweya entrapment, palibe madontho madzi, ndipo palibe thovu mdima, amene mwachindunji zimakhudza ngati wotsatira electroplating matuza. Kudyetsa koyenera ndi slagging. Nkhunguyo imaponyedwa pansi. , Palibe madontho a madzi.

 2. Kukula kwa nkhungu yoponya kufa

Pakukula kwa nkhungu zoponyera kufa, matani, kupanikizika, kupanikizika kosakwanira, komanso kutopa kosakwanira kwa makina omangira ziyeneranso kuganiziridwa. Ziribe kanthu momwe chithandizo chisanachitike cha plating chimathetsedwa, nthawi zonse pamakhala matuza 20-30%. Chikombolecho chimatsekedwa ndikusinthidwa kukhala Zidutswa zingapo, palibe kubwezanso pambuyo pakuyika.

3. Pre-mankhwala pamwamba

Malo opangira mankhwala amadzimadzi opukuta, phala lopukuta, ndi wosanjikiza wa oxide samatsukidwa, ndipo nthawi zambiri pamakhala kugudubuza. Zinc alloy die-casting pambuyo pakugudubuza ndi yowala. Ogwira ntchito ambiri munjira yopangira ma electroplating plant pickling amawotchedwa mwachisawawa. Wopukuta wophatikizidwa pamwamba samatsukidwa, ndipo matuza amapezeka nthawi zambiri. Kuphatikiza apo, kalendala yomwe imagwiritsidwa ntchito ndi chomera cha calendering ndi kupukuta imakhalanso ndi ubale wabwino, ndipo zina zopezeka mu kalendala zimakhala zovuta kutsuka.

4. Pamene mankhwala alowa mkuwa wamchere

Mankhwalawa asanalowe mu thanki yazitsulo zamkuwa, zinc alloy die-casting parts akadali ndi filimu yakuda yomwe siipangidwa ndi filimu ya oxide kuchotsa sera ndi mafuta. Chifukwa chake, kuchotsedwa kwa membrane ndikofunikira kwambiri. M'zaka zoyambirira, imatha kuchotsedwa pogwiritsa ntchito mchere wotsutsa. Kutetezedwa kwachilengedwe kwapano sikulola kutulutsa madzi otayira okhala ndi mchere wotsutsa.

5. thanki yazitsulo zamkuwa zamkuwa

Pali zinthu zambiri za organic mu thanki ya zamkuwa zamkuwa, ndipo pali zonyansa zambiri, ndipo cyanide yaulere palibe. Yesani zosakaniza za thanki yamkuwa yamchere kuti muwone ngati sodium cyanide ndiyotsika kapena sodium hydroxide ndiyokwera! Zovuta kwambiri, tikulimbikitsidwa kuti tigwiritse ntchito kaboni kamodzi masiku 3-5 aliwonse.

6. Conductivity ya alkali mkuwa yamphamvu

The conductivity wa yamphamvu yamkuwa zamchere ndi zofunika kwambiri. Kaya anode yasungunuka bwino ndipo mbale yamkuwa ya anode ndiyokwanira kumayambitsa matuza.

7. Mankhwalawa amatuluka thovu atatuluka mu uvuni

Zitha kuchitika chifukwa cha kutentha kosafanana kwa uvuni, ndiko kuti, kutentha kumakhala kokwera kwambiri. Chifukwa chosowa kumangika panthawi yakufa, zimakhala zosavuta kuti asidi alowe m'madzi otayira trachoma a zinc alloy die castings.Asidi ndi zinki zimagwirabe ntchito ngakhale ngati pali zokutira pamwamba, zomwe zimapanga kuchuluka kwa haidrojeni H. .Pamene kupanikizika mkati ndi apamwamba kuposa kuthamanga mumlengalenga Kumlingo wakutiwakuti, kuwonjezera kutentha kumatulutsa thovu.
