Ongororo yeZvikonzero Zvekukanganisa muDie Castings

Zinc alloykufa-kukanda zvikamuiye zvino ari kushandiswa kune zvakasiyana-siyana zvigadzirwa.Akasiyana siyana emagetsi nemidziyo yemagetsi akakomberedzwa ne zinc alloy die-casting products.Naizvozvo, kunaka kwepamusoro kweiyo castings kunodiwa kuve kwakakwira, uye kugona kwakanaka kwepamusoro kurapwa kunodiwa.Chikanganiso chinowanzoitika chezinc alloy casting products is surface blistering.

Kukanganisa maitiro: Kune akasimudzwa vesicles pamusoro peiyokufa kukandira.① Yakawanikwa mushure mekufa-kukanda;② Yakazarurwa mushure mekupenya kana kugadzirisa;③ Inoonekwa mushure mekupfapfaidza mafuta kana electroplating;④ Yakaonekwa mushure mekuiswa kwenguva yakati.

Mazhinji ekuputika pamusoro pezinc alloy anokonzerwa nemapores, uye pores anonyanya kuputika uye shrinkage maburi.Mapores anowanzo kutenderera, uye mazhinji emakomba ekudonha haana kurongeka.

1. Zvinokonzera pores: ① Panguva yekuzadza uye kusimba kwesimbi yakanyungudutswa, maburi anoumbwa pamusoro kana mukati mekukanda nekuda kwekupindirwa kwegasi;② gasi rakapindirwa nekuputika kwejasi;③ iyo gasi yemukati meiyo alloy fluid yakawandisa uye inonaya panguva yekusimba.

2. Zvikonzero zvekudzikira mhango: ①Mukuita kwekusimba kwesimbi yakanyunguduka, shrinkage mhango inoitika nekuda kwekuderedzwa kwevhoriyamu kana chikamu chekupedzisira chakasimba hachigone kudyiwa nesimbi yakanyungudutswa;②Ukobvu husina kuenzana hwekukanda kana kuwandisa kwechidimbu kwekukanda kunoita kuti chimwe chikamu Kubatana kunonoke, uye mapako anoumbwa pamusoro kana vhoriyamu yadzikira.

Nekuda kwekuvapo kwemapores uye shrinkage maburi, maburi anogona kupinda kana zvikamu zvekufa-kandira zvinoiswa pasi pekurapwa.Paunenge uchibika mushure mekupenda uye electroplating, gasi riri mugomba rinowedzera nekupisa;kana kuti mvura iri mugomba inoshanduka kuita mupfunga, izvo zvinozoita kuti pave nemablister pamusoro pekukanda.
