Matanda emumugwagwa anoshandiswa nemagetsi ezuva anofanira kuvharwa nemagetsi anotonhora here kana kuti anopisa here?

Mazuva ano, ma coil esimbi emhando yepamusoro eQ235 ndiwo anonyanya kufarirwa pakugadziramapango emigwagwa ezuva.Nekuti mwenje yemumugwagwa inopiswa nemhepo, zuva, nemvura, hurefu hwayo hunoenderana nekukwanisa kwayo kutsungirira ngura. Simbi inowanzo shandiswa nemagetsi kuti izvi zvivandudzwe.

Kune mhando mbiri dzezinc plating: hot-dip uye cold-dip galvanizing.mapango esimbi anopisa-kunyikaDzinodzivirira ngura zvakanyanya, tinowanzo kurudzira kuti dzitenge. Ndeipi musiyano uripo pakati pemagabha ekupisa nekudzika nechando, uye nei magabha ekupisa achidzivirira ngura zvakanyanya? Ngatitarisei Tianxiang, fekitori yematanda emumugwagwa inozivikanwa muChina.

1) Kugadzira Magirazi Akatonhora (Zvinonziwo electro-galvanizing): Mushure mekudzima mafuta nekukanda, simbi inoiswa mumunyu wezinc. Mhinduro yacho yakabatana neelectrode isina kunaka yemuchina we electrolysis, uye zinc plate inoiswa yakatarisana, yakabatana neelectrode isina kunaka. Kana simba ravhurwa, sezvo magetsi achifamba akananga kubva kune positive kuenda kune negative electrode, zinc deposit layer yakafanana, yakakora, uye yakabatana zvakanaka inoumbwa pamusoro pepombi yesimbi.

2) Kupisa-kunyika galvanizing: Pamusoro pesimbi inonyudzwa mu zinc yakanyungudutswa mushure mekucheneswa uye kushanda. Rutivi rwe zinc yesimbi runokura pamusoro pesimbi nekuda kwekuita kwe physicochemical pakati pesimbi ne zinc panzvimbo inopindirana. Kana tichienzanisa ne cold galvanizing, nzira iyi inoita kuti pave nechisungo chakasimba pakati pe coating ne substrate, zvichivandudza huwandu hwe coating, kugara kwenguva refu, kushanda pasina kugadzirisa, uye kushanda zvakanaka.

1) Nzira Yokugadzirisa: Mazita avo anoita kuti musiyano uve pachena. Zinc inowanikwa patembiricha yemumba inoshandiswa mumapombi esimbi akavharidzirwa anotonhora, nepo zinc inowanikwa pa450°C kusvika 480°C inoshandiswa mukupisa-kunyudza.

2) Ukobvu hweCoating: Kunyangwe cold-dip galvanizing ichiwanzoita kuti coating point ive 3–5 μm chete, izvo zvinoita kuti kugadzirisa kuve nyore, haina ngura. Kusiyana neizvi, hot-dip galvanizing inowanzoita kuti coating point ive 10μm kana kupfuura, iyo inodzivirira ngura kakawanda kupfuura cold-dip galvanized light poles.

3) Maumbirwo Ekuvhara: Kuvhara nepasi pevhu zvinoparadzaniswa nechikamu chakapfava chinoshandiswa mukupisa-kudzika galvanizing. Zvisinei, nekuti jira racho rakagadzirwa ne zinc chete, izvo zvinoita kuti rive nejira rakafanana rine maburi mashoma, zvichiita kuti risanyanya kukuvadzwa nengura, izvi hazvina zvazvinobatsira pakudzivirira ngura. Kusiyana neizvi, galvanizing inonyudzwa nechando inoshandisa jira rakagadzirwa nemaatomu e zinc uye nzira yekunamatira ine maburi akawanda, izvo zvinoita kuti rive nyore kubatwa nengura munzvimbo dzakatikomberedza.

4) Musiyano weMitengo: Kugadzirwa kwemagetsi anodziya nekudziya kwakanyanya kuoma uye kwakaoma. Nokudaro, makambani madiki ane michina yekare anowanzo shandisa magetsi anodziya nekudziya, zvichikonzera mitengo yakaderera zvikuru. Vagadziri vakuru uye vagara varipo vemagetsi anodziya vanowanzova nekutonga kwakanaka kwemhando yepamusoro, zvichikonzera mitengo yakakwira.

Vamwe vanhu vangati kunyangwe vachiziva musiyano uripo pakati pe "cold-dip galvanizing" ne "hot-dip galvanizing", havazivi musiyano. Idzi inzira dzekugadzirisa dzisingaonekwe nemaziso. Ko kana mutengesi asina hunhu achishandisa "cold-dip galvanizing" pachinzvimbo che "hot-dip galvanizing"? Kutaura zvazviri, hapana chikonzero chekunetseka. "Cold-dip galvanizing" uyekunyudza nekupisazviri nyore kusiyanisa.

Nzvimbo dzakaita semagirazi dzinotonhorera dzakatsetseka, kunyanya dzegirini-yero, asi dzimwe dzinogona kunge dzakatsvuka, chena-yebhuruu, kana chena dzine kupenya kwegirini. Dzinogona kutaridzika sedzisina kujeka kana kuti dzakasviba. Nzvimbo dzakaita semagirazi dzinopisa, kana tichienzanisa, dzinenge dzakaomarara, uye dzinogona kunge dzakatumbuka zinc, asi dzinotaridzika kupenya zvikuru uye kazhinji dzine ruvara rwesirivha-chena. Nyatsoteerera misiyano iyi.
