Theruvara simbi ndiromumhepo yakapoteredza pasi inoratidzirwa kuchiedza chezuva, mhepo, jecha, mvura, sinou, chando nedova, pamwe chete nokushanduka kwetembiricha nehunyoro gore rose.Izvi zvese zvikonzero zvinoita kuti mavara esimbi aite ngura.Saka sei kuvadzivirira?
1. Thermal spray aluminum composite coating
Iyi inzira inogara kwenguva refu yekudzivirira ngura iyo inoshanda sekupisa-dip galvanizing.Iyo chaiyo nzira ndeyekutanga sandblast uye kubvisa ngura pamusoro pezvikamu zvesimbi kuratidza kupenya kwesimbi uye roughen pamusoro.Zvadaro shandisa murazvo weacetylene-oxygen kunyungudusa waya yearuminiyamu inoramba ichidyiswa, uye shandisa mweya wakadzvanywa kuifuridzira pamusoro pechikamu chesimbi kuita muzinga wealuminium spray coating.Pakupedzisira, capillary pores inozadzwa nependi yakadai sepoxy resin kana neoprene pendi kuti iite jira rinosanganiswa.Iyi nzira haigone kushandiswa pamadziro emukati ezvikamu zvetubula, saka migumo yese yetubular components inofanira kunge yakavharwa nemhepo kuitira kuti madziro emukati arege kupera.
2. Coating nzira
Iyo anti-corrosion zvimiro zvemitoo yekupfekedza kazhinji haina kunaka senzira dzenguva refu dzekudzivirira ngura.Naizvozvo, kune akawanda emukati simbi zvimiro kana kunze simbi zvimiro zviri nyore kudzivirira.Nhanho yekutanga pakuvaka nzira yekuputira ndeyekubvisa ngura.Yakanakisa coating inotsamira pakunyatsobvisa ngura.Naizvozvo, machira ane kudiwa kukuru anowanzo shandisa jecha uye kuputika kwepfuti kubvisa ngura, kuburitsa kupenya kwesimbi, uye kubvisa ngura nemafuta ese.Coatings inoshandiswa pa-saiti inogona kubviswa nemaoko.Kusarudzwa kwekuputira kunofanira kufunga nezvenzvimbo yakapoteredza.Zvipfeko zvakasiyana zvine kushivirira kwakasiyana kune mamiriro akasiyana ekuora.Coatings kazhinji inosanganisira primer uye topcoat.Iyo yekutanga ine hupfu hwakawanda uye hushoma hwaro zvinhu.Iyo firimu ine rough, ine yakasimba kunamatira kusimbi, uye ine yakanaka kunamatira kune topcoat.Iyo topcoat ine zvinhu zvakawanda zvepasi uye iyo firimu inopenya, iyo inogona kudzivirira iyo primer kubva mumhepo yekuora uye kuramba mamiriro ekunze.
Pane mibvunzo pamusoro pekuenderana kwemajasi akasiyana.Paunosarudza zvipfeko zvakasiyana-siyana zvisati zvaitika uye shure, unofanirwa kubhadhara kuenderana kwavo.Iyo yekupfekedza inofanira kuiswa nekudziya kwakakodzera uye humidity.Nzvimbo yekuvaka yekuputira inofanira kunge isina guruva shoma uye hapafaniri kuva nekugadzirisa pamusoro pezvikamu.Usafumure kunaya mukati maawa mana mushure mekupenda.Iko kupfeka kunowanzoitwa 4 kusvika ku5 nguva.Ukobvu hwese hwefirimu rependi yakaoma 150μm yemapurojekiti ekunze uye 125μm yemapurojekiti emukati, paine kukanganisa kunobvumidzwa kwe25μm.Pamhenderekedzo yegungwa kana pagungwa kana mumhepo inoparadza zvakanyanya, huwandu hwakakwana hwefirimu yepende yakaoma inogona kuwedzerwa kusvika 200 ~ 220μm.
3. Cathodic kudzivirira nzira
Kubatanidza simbi yakanyatsojeka pamusoro pechimiro chesimbi kunotsiva kukora kwesimbi.Inowanzoshandiswa mumvura yepasi pemvura kana pasi pevhu.Mavara esimbi mataira chinhu chinodhura zvakanyanya.Kunyangwe iyo yekutanga mari yekudyara ingaite senge yakawandisa, maererano nemitengo yenguva refu yekushandisa, inochengetedza mutengo nekuti chigadzirwa chine hupenyu hurefu hwesevhisi uye hapana nzvimbo.Pane mamiriro ekutsiva.Kwatiri, inochengetedza basa, kushanda nesimba uye mari.
Ndinovimba kuti chinyorwa ichi chinobatsira kwauri.Ndokumbira uvhare webhusaiti ino kuti uwane nhau dzakagadziridzwa.
