Nzira yekudzivirira sei galvanized simbi pombi kubva chena ngura

Sezvatinoziva tose, kana muviri wepombi yesimbi yakarwiswa uye iyo zinc hydroxide compounds yakaumbwa, zvinodikanwa kubvisa zvigadzirwa zve oxide kubva pamusoro. Kazhinji kutaura, kune zvikonzero zviviri zvikuru: 1.kuvapo kwavo kunodzivisa kuumbwa kwekugadzikana kwecarbonate based oxides; 2. mhedzisiro yekuputira yakakwenenzverwa inogona kubva padiki kusvika kune yakanyanya kuomarara uye akasiyana siyana ekugadzirisa kurapwa aripo kuti agadzirise matambudziko akachena ngura pamatanho akasiyana-siyana ayo anogona kuitika.

Kune mashoma marapirwo anokurudzirwa kubata newhite rust pazvigadzirwa zvemalavani sezvinotevera:

1. Light White Rusting
Izvi zvinoratidzwa nekuumbwa kwefirimu rakareruka rewhite powdery residue uye rinowanzoitika pamapombi esimbi ekugadzira panguva yekunaya kwemvura. Zvinonyanya kuoneka pane nzvimbo dzakatemerwa kana kufayerwa panguva yemhando yekusimbisa mabasa. Mishonga iyi inobvisa nzvimbo yakavharwa kubva pairi uye inofumura unoxidised zinc kurwisa kubva mumvura inonaya. Chero bedzi zvinhu zvacho zvanyatsofefeterwa uye zvakanyoroveswa, ngura chena haiwanzo pfuura nepamusoro pedanho iri. Inogona kubviswa kana zvichidikanwa asi kazhinji inogezwa musevhisi nemamiriro ekunze akajairika. Hapana kurapwa kwekugadzirisa kunowanzodiwa padanho iri.
2. Mwero Muchena Wepakati
Izvi zvinoratidzwa nekusviba kunooneka uye kuoneka kwechivharo chemarara pasi penzvimbo yakakanganisika, nekuumbwa kwewhite rust kuchiita kunge kwakakura. Ukobvu hwekufukidzira hunofanirwa kutariswa nenyanzvi dzekugadzira pombi dzesimbi kuti vaone kuwanda kwekurwiswa kwejasi. Muzvizhinji zvezviitiko, pasi pe5% yejasi yakavharidzirwa ichave yabviswa uye naizvozvo hapana basa rekugadzirisa rinofanirwa kudiwa chero bedzi kuonekwa kwenzvimbo yakakanganiswa kusingakanganisi kushandiswa kwechigadzirwa uye zinc hydroxide residues. kubviswa nekukwesha waya.
3. Ngura Yechena Yakanyanya
Izvi zvinoratidzwa nekurema kwazvo oxide deposits. Somuenzaniso, izvozvo zvinowanzoitika apo pane pombi dzesimbi dzakawanda dzinotonhora dzakabatanidzwa pamwe chete. Nzvimbo dziri pasi penzvimbo ine oxidized inogona kunge yakaita dema uye inoratidza zviratidzo zve red rust. Cheki yekuvharisa ukobvu inozoona kuti iyo galvanized coating yakakuvadzwa kusvika papi. Mumamiriro ezvinhu akadaro, zvinokurudzirwa kuti tiise waya bhurashi kana kubhura nzvimbo yakakanganisika kuti tibvise zvese oxidation zvigadzirwa uye ngura kana iripo. Kana kuti tinoisa jasi rimwe chete kana maviri ependi yakatenderwa epoxy zinc-rich kuti tiwane inodiwa yakaoma firimu ukobvu hwe100 microns zvishoma.
