Zvinhu zvakatipoteredza zvinokanganisa mavara ane mavara-akavharidzirwa
Tatarisana nemhando dzakasiyana-siyana dzekupfeka, tinofanira kusarudza sei?Rega ndiunze zvakati wandei zvakatipoteredza zvinokanganisa kushandiswa kwemavara-akavharwa mabhodhi.
1. Tembiricha
Iyo yekupfeka iri nyore kupfava pakupisa kwepamusoro, uye svikiro rinopisa riri nyore kunamatira.Zviri nyore kupinda mu substrate, iyo okisijeni iri mumvura ichawedzera pakupisa kwakanyanya, uye chiyero chekuora chichawedzera pane imwe tembiricha.
2. Humidity
Kuora kweiyo substrate pakuchekwa nekugadzirisa kukuvadzwa kwebhodhi-yakavharwa kwebhodhi ndeye electrochemical corrosion, uye hunyoro hushoma hazvisi nyore kugadzira bhatiri rekuora (kureva electrochemical circuit).
3, Musiyano wekushisa pakati pemasikati neusiku
Musiyano mukuru wetembiricha uri nyore kudzikisira, uchigadzira galvanic corrosion mamiriro pasimbi isina chinhu.Uye zvakare, iyo yakakura tembiricha mutsauko unotungamira kune kazhinji kutonhora uye kupisa deformation yejasi, iyo inomhanyisa kuchembera uye kusununguka kwejasi, uye yekunze corrosive medium inopinda nyore mu substrate.
4. Kupenya kwezuva nguva uye kusimba
Kutarisa uye kutsetseka kunokanganisa nguva yezuva uye nekudaro kusimba kwejasi.Kutsetseka kunokanganisawo nguva yekugadzika kwezvinoparadza midhiya kana huruva pandiro yesimbi.Chiedza chezuva mafungu emagetsi, ayo akakamurwa kuita gamma rays, X-rays, ultraviolet mwaranzi, mwenje unooneka, infrared mwaranzi, microwaves uye masaisai eredhiyo zvinoenderana nesimba rawo uye frequency.Masaisai nemasaisai eredhiyo ane simba rakaderera uye haadyidzane nezvinhu.Infrared zvakare ine yakaderera-simba spectrum.Inogona chete kutambanudza kana kupeta zvisungo zvemakemikari zvezvinhu, asi hazvigone kuzvityora.Chiedza chinooneka chinopa zvese mavara akapfuma.Iyo UV spectrum ndeye yakakwira-frequency mwaranzi, ine simba guru rekuparadza kupfuura yakaderera-energy spectrum.Sezvatinoziva, mavara akasvibira paganda negomarara reganda zvinokonzerwa nemwaranzi yeultraviolet yezuva.Saizvozvo, UV inogona zvakare kutyora makemikari zvisungo zvezvinhu, zvichiita kuti atyoke.Izvi zvinoenderana ne UV wavelength uye kemikari bond simba rechinhu.X-rays ine mhedzisiro inopinza.Gamma mwaranzi inogona kutyora kemikari zvisungo zvezvinhu uye kugadzira maion anochajwa mahara.Izvi zvinouraya kune organic matter.Sezvineiwo, mwaranzi iyi mishoma muchiedza chezuva.Nokudaro, zvinogona kuonekwa kubva pamusoro apa kuti nguva yezuva uye kusimba kunobata kugadzikana kwechimiro chekuputira, kunyanya munzvimbo dzine simba re ultraviolet rays.
5. Kunaya uye acidity
Acidity yekunaya kwemvura pasina mubvunzo inokanganisa kusaita ngura.Zvisinei, kunaya kwemvura kune mativi maviri.Pamadziro nemadziro edenga ane materu akakura, kunaya kwemvura kunogona kuchenesa pamusoro pemarata esimbi nekusuka zvinogadzirwa necorrosion.Zvisinei, kumapuranga edenga ane nzvimbo dzakadzika uye nzvimbo dzine mvura isina kunaka, mvura yakawanda inonaya Zviri nyore kuita kuti kuora kuwedzere.
6. Mhepo nzira uye nekukurumidza
Mhedzisiro yekutungamira kwemhepo uye kumhanya kwemhepo kwakafanana neyemvura, uye ivo vanowanzoperekedzwa.Icho chiedzo chekubatana kwezvinhu, nokuti mhepo ichaita kuti kushamwaridzana kusunungurwe uye mvura inonaya inopinda mukati meimba.
7. Corrosion uye sedimentation
Semuyenzaniso, chloride ions, sulfur dioxide, zvichingodaro zvine acceleration effect pakuora, uye madhamu aya anonyanya kuitika kumahombekombe egungwa uye munzvimbo dzine kusvibiswa kwakakomba kwemaindasitiri (senge zvirimwa zvemagetsi, zvinonyungudutsa, nezvimwewo).
