Chinangwa chekutonhora galvanizing uye inopisa galvanizing yemapango emwenje ezuvandeyekudzivirira kuora uye kuwedzera hupenyu hwebasa remarambi ezuva remumugwagwa, saka chii chakasiyana pakati pezviviri?
1. Chitarisiko
Kuonekwa kwekutonhora kwe galvanizing kunotsvedza uye kupenya.Iyo electroplating layer ine color passivation process inonyanya yeyero uye yegirini, ine mavara manomwe.Iyo electroplating layer ine white passivation process ine bluish chena, uye ine ruvara zvishoma mune imwe kona yechiedza chezuva.Zviri nyore kubudisa "kupisa kwemagetsi" pamakona uye kumucheto kwetsvimbo yakaoma, iyo inoita kuti zinc layer pane chikamu ichi chiwedzere.Zviri nyore kuumba ikozvino pakona yemukati uye kubudisa pasi-ikozvino grey nzvimbo, iyo inoita kuti zinc layer munzvimbo iyi iite shoma.Tsvimbo haifaniri kunge isina zinc bundu uye agglomeration.
Chitarisiko chekupisa chinopisa chakati shwarara pane chiya chinotonhora chinopfuta, uye chichena chesirivha.Chitarisiko chiri nyore kubudisa maitiro emvura zviratidzo uye madonhwe mashomanana, kunyanya kune imwe mugumo wetsvimbo.
Iyo zinc layer yeyakaomesesa inopisa galvanizing yakawanda nguva yakakora kupfuura inotonhora galvanizing, uye kudzivirira kwayo kwemarara zvakare kakapetwa kakawanda eiyo yemagetsi galvanizing, uye mutengo wayo wakasikwa wakakwira zvakanyanya kupfuura iwo wekutonhora kwekuputika.Zvisinei, nekufamba kwenguva, kupisa kunopisa nekudzivirira ngura kwemakore anopfuura gumi kuchave kwakakurumbira kudarika kutonhora kunopisa nekudzivirira ngura kwemakore 1-2 chete.
2. Maitiro
Cold galvanizing, iyo inozivikanwawo se galvanization, ndeye kushandisa electrolytic midziyo kuisa tsvimbo mumushonga une zinc munyu mushure mekubvisa uye kunhonga, uye kubatanidza danda risina kunaka remagetsi emagetsi.Isa zinc plate kune rimwe divi retsvimbo kuti uisanganise nechakanaka danda remagetsi emagetsi, batanidza magetsi, uye shandisa mafambiro emhepo kubva padanda rakanaka kuenda padanda risina kunaka kuti uise zingi. pane workpiece;Kupisa galvanizing ndiko kubvisa mafuta, asidhi wash, kunyudza mushonga uye kuomesa workpiece, uye woinyudza mune yakanyungudutswa zinc mhinduro kwenguva yakati, uye wozoibvisa.
3. Coating structure
Iko kune chidimbu chebrittle compound pakati pekuputira uye substrate yekupisa galvanizing, asi izvi hazvina simba guru pakudzivirira kwayo kwekuora, nokuti kupfekedza kwayo kwakachena zinc coating, uye kupfekedza kwakafanana, kusina pores, uye hakusi. zviri nyore kusvibiswa;Nekudaro, iyo yekuputira inotonhora galvanizing inoumbwa nemamwe maatomu ezinc, ari ekunamatira kwemuviri.Kune akawanda ma pores pamusoro, uye zviri nyore kukanganiswa nemhoteredzo uye marara.
4. Musiyano pakati pezviviri
Kubva pamazita evaviri, tinofanira kuziva musiyano.Zinc mune inotonhora galvanized simbi pombi inowanikwa pakamuri tembiricha, nepo zingi mune inopisa galvanizing inowanikwa pa450 ℃ ~ 480 ℃.
5. Coating ukobvu
Ukobvu hwekutonhora hwekuputira galvanizing kazhinji hungori 3 ~ 5 μ m.Izvo zviri nyore kwazvo kugadzirisa, asi kupikisa kwayo kwegora hakuna kunaka kwazvo;Iyo inopisa-dip galvanized coating kazhinji ine 10 μ Kudzivirirwa kwehutu hwehupamhi hwem uye kumusoro kuri nani zvakanyanya, izvo zvingangoita makumi enguva iyo yedanda remwenje rinotonhora.
6. Kusiyana kwemutengo
Kupisa galvanizing kunonyanya kunetsa uye kunoda mukugadzira, saka mamwe mabhizinesi ane midziyo yechinyakare uye diki diki anowanzo tora inotonhora yekuvhenekesa maitiro mukugadzira, iyo yakaderera zvakanyanya mumutengo uye mutengo;Zvisinei,inopisa-dip galvanizing vagadzirikazhinji dzakanyanya kurongeka uye dzakakura pamwero.Vane kutonga zviri nani pamusoro pehutano uye mari yakakwirira.
Iyo misiyano iri pamusoro pakati pekupisa galvanizing uye kutonhora galvanizing ye solar street mapango emwenje yakagovaniswa pano.Kana matanda emwenje emumugwagwa wezuva achizoshandiswa munzvimbo dzemahombekombe, anofanirwa kufunga nezvekudzivirira kwemhepo uye kusagadzikana kwekuora, uye usagadzira chirongwa chemarara nekuda kwekukara kwenguva pfupi.
