Kupisa dip galvanizing inzira yekurapa pamusoro iyo inosanganisira kunyudza zvikamu zvakagara zvakarapwa mubhavhu rezinc kuitira kudziya kwepamusoro-soro metallurgical reactions kuita zinc coating Matanho matatu ekupisa dip galvanizing ndeaya anotevera:
① Iyo pamusoro pechigadzirwa inonyungudika ne zinc fluid, uye iyo iron based surface inonyungudutswa ne zinc fluid kuti iite zinc iron alloy phase.
② Maion e zinc ari mu alloy layer anowedzera kupararira akananga kumatrix kuita zinc iron mutual solution layer; Simbi inoumba zinc iron alloy panguva yekunyunguduka kwe zinc solution uye inoramba ichipararira yakananga kunharaunda yakatenderedza Nzvimbo ye zinc iron alloy layer yakaputirwa ne zinc layer, inotonhorera nekupenya patembiricha yekamuri kuti igadzire coating. Parizvino, iyo inopisa dip galvanizing process yemabhaudhi yave kuwedzera kukwana uye kugadzikana, uye ukobvu hwekufukidzira uye kushorwa kwegora kunogona kuzadzisa zvizere zvinodikanwa zve-anti-corrosion zvemhando dzakasiyana dzemichina. Nekudaro, kuchine matambudziko anotevera mukugadzirwa chaiko uye kuisirwa kwemashini zvivakwa:
1. Pane shoma shoma yezinc yakasara pamucheka webhoti, iyo inokanganisa kuiswa,
2. Kupesvedzera pasimba rekubatanidza kunowanzo kuwanikwa nekuwedzera machining allowance ye nati uye kudzoreredza kumashure mushure mekuputirwa kuti ive nechokwadi chekuenderana pakati peinopisa-dip galvanized nati nebhaudhi. Kunyangwe izvi zvichivimbisa kukwana kweiyo fastener, mechanical performance test inowanzoitika panguva ye tensile process, iyo inokanganisa simba rekubatanidza mushure mekuiswa.
3. Mhedzisiro pamagetsi emagetsi e-high-simba mabhaudhi: Isina kunaka inopisa-dip galvanizing process inogona kukanganisa kukanganisa kuoma kwemabhaudhi, uye kushambidzwa kweasidhi panguva yekugadzira galvanizing kunogona kuwedzera huwandu hwehydrogen mumatrix e10.9 giredhi yakakwirira-simba mabhoti. , kuwedzera mukana wehydrogen embrittlement. Tsvagiridzo yakaratidza kuti michina yezvikamu zvakarukwa zve-high-simba mabhaudhi (giredhi 8.8 uye pamusoro) mushure mekupisa-dip galvanizing ine kumwe kukuvadza.
Mechanical galvanizing inzira inoshandisa muviri, makemikari adsorption deposition, uye mechanical kudhumhana kuumba kufukidza kwesimbi hupfu pamusoro pechishandiso patembiricha yekamuri uye kumanikidzwa. Nokushandisa nzira iyi, machira esimbi akadai seZn, Al, Cu, Zn-Al, Zn-Ti, uye Zn-Sn anogona kuumbwa pazvikamu zvesimbi, zvichipa kudzivirira kwakanaka kwesimbi yesimbi substrate. Iyo mechanical galvanizing process pachayo inosarudza kuti ukobvu hwekuputira hweshinda nemagrooves hutete pane hwenzvimbo dzakati sandarara. Mushure mekuputira, nzungu haidi kudzoserwa kumashure, uye mabhaudhi pamusoro peM12 haatombodi kuchengetedza kushivirira. Mushure mekuputira, haikanganisi iyo yakakodzera uye michina zvinhu. Nekudaro, saizi yezinc poda inoshandiswa mukuita, kusimba kwekudya panguva yekugadzira, uye nguva yekudya inobata zvakananga kuwanda, kupfava, uye kutaridzika kwejasi, nekudaro zvichikanganisa kunaka kwekupfeka.
