Anodizing maitiro anoshandiswa kugadzira aluminium oxide firimu pamusoro pechiso chealuminium kana aluminium alloy zvigadzirwa. Izvo zvinosanganisira kuisa iyo aluminium kana aluminium Alloy chigadzirwa seinoye mumhinduro yeElectrolyte uye kushandisa magetsi aripo kuumba iyo aluminium oxide firimu. Anodizing anovandudza kudzivisa kupesana, pfeka kurwisa, uye zvigadzirwa zvekushongedza zvealuminum profiles. Munguva yeAnodizing maitiro eAluminium profiles, akati wandei hurema maitiro anogona kuitika. Ngatinyanyo kuti tinzwisise zvinokonzeresa zvine mavara. Corroson Corroson, bhati kusvibiswa, kupusa kweiyo alloy yechipiri zvikamu, kana gallantic mhedzisiro inogona kutungamira kune yakajeka kuremara. Ivo vanotsanangurwa seinotevera:
1.Cid kana alkali etching
Asati edodizing, iyo aluminium zvinyorwa zvinogona kugadzirwa neAcid kana alkaline zvinwiwa, kana zvakakanganiswa neAcid kana alkaline mafuti, zvichikonzera mukati menzvimbo chena mavara pamusoro. Kana iyo corrostion ikanyanya, yakakura pombi dzinogona kuumba. Zvakaoma kuziva neziso rakashama kunyangwe iyo corroso inokonzerwa neAcid kana Alkali isiyaniswa nekuona iyo yekucherekedza chikamu chenzvimbo yakashongedzwa pasi pe microscope. Kana pasi pegomba rikatenderera uye pasina kuwirirana corroson, inokonzerwa naAlkali Etching. Kana pasi racho risingaiti uye rinoperekedzwa nekudyidzana corroson, nemakomba akadzika, zvinokonzerwa neakaruki. Kuchengetedza zvisina kunaka uye kubata mufekitori kunogona kutungamirawo kune urwu rudzi rwekuora. Acid fumes kubva kumakemikari kupukuta vamiririri kana mamwe maacidic mafuru, pamwe neklorinated organic organic degreasers, ndezvinyorwa zve acid etching. Zvakajairika Alkali Etching anokonzerwa nekuparadzira uye kupaza mongwe, simendedsh, uye alkaline kugeza zvinwiwa zvinwiwa. Kamwe kukonzeresa kuchikonzera, kusimbisa manejimendi emabasa akasiyana siyana mufekitori kunogona kugadzirisa dambudziko.
2.atmosheric Corrosion
Aluminium profiles yakaratidzwa mumhepo yakanyorova inogona kukudziridza mavara machena, ayo anowanzoenderana nemitezo yemitsara yemukati. Atmospheric Corrosion kazhinji haina kunyanyisa seakashata kana Alkali etching uye inogona kubviswa nenzira dzemuchina kana ma alkaline kugeza. Atmospheric Corrosion inonyanya kusarudzika uye inowanzoitika uye inowanzoitika pane imwe nzvimbo, yakadai seyakaderera tembiricha inovhara mvura inovhara kana pane yepamusoro nzvimbo. Kana kuora kweAtmosperic kwakanyanya, muchinjiko-chikamu chemagwendefa emapipi chinoonekwa semutengo wakamiswa. Mune ino kesi, kushambidzika kweAlkaline hakugone kubvisa nzvimbo dzakadzika uye dzinogona kutovawedzera. Kana kuora kwechiitiko kwakaitwa, mamiriro ekuchengetedza mufekitori kunofanirwa kuongororwa. MaAluminium Zvigadzirwa hazvifanirwe kuchengetwa munzvimbo dzine kunyanyisa kudziya kupisa kudzivirira kwemvura kukuvara kwemvura kudzikisira. Nzvimbo yekuchengetera inofanira kunge yakaoma, uye tembiricha inofanira kunge iri yunifomu sezvinobvira.
3.Paper Corrosion (mavara emvura)
Kana bepa kana kadhibhodi yakaiswa pakati pealuminium zvinhu kana kushandiswa pakutora, inodzivirira abrasion. Nekudaro, kana bepa rikave rakanyorova, mavara eColrosion anoonekwa pamusoro peiyo aluminium. Kana Corrugated kadhibhodi inoshandiswa, nguva dzose dzemitsetse yemavara eCorrosion inoonekwa pane iyo pfungwa dzekusangana nedare rakarukwa. Kunyangwe zvikanganiso zvinogona dzimwe nguva zvichiri kuoneka zvakananga pane iyo aluminium pamusoro, vanowanzo kududzwa mushure mekugezesa alkaline uye anodizing. Aya mavara anowanzove akadzika uye akaoma kubvisa nenzira yemuchina kana ma alkaline kugeza. Pepa (bhodhi) Corrosion inokonzerwa neacid ion, kunyanya so42- uye cl- iripo mupepa. Naizvozvo, kushandisa pepa (bhodhi) pasina chlorides uye susfates uye kudzivisa kupinza kwemvura inzira dzinobudirira dzekudzivirira pepa (bhodhi) corrosion.
4.cleaning corrosion yemvura (zvakare inozivikanwa sechando chechando corrosion)
Mushure mekugeza Alkaline, kana kupukuta kwemakemikari, kana sulfuric acid kutora, kana mvura yekunguruka ine tsvina, inogona kuguma nemavara-akaumbwa kana kupenya kana kupenya mavara pamusoro. Kudzika kwekoramu kwakadzika. Rudzi urwu rwecorosi runoitika kana mvura yekuchenesa ichisvibiswa zvakanyanya kana kana iyo yekuyerera kwemufashama yekunyura yakaderera. Yakafanana nechando chechando-chakakomberedzwa makristasi, saka zita rekuti "Snowflake Corrosion." Chikonzero ndechekuti maitiro ekutsamwa kweZinc muAluminium neSE42- uye cl- mumvura yekuchenesa. Kana iyo yekubatanidzwa kwetangi iri murombo, galanic mhedzisiro inogona kuwedzera kuremara uku. Maererano nezvinyorwa zvekunze, apo zvirimo zveZn muAluminium Alloy yakakura kupfuura 0.015%, iyo cl- mumvura yekuchenesa yakakwira kupfuura 15 PPM, rudzi urwu rwezvakashata runogona kuitika. Uchishandisa nitric acid yekukora kana kuwedzera 0.1% HNO3 kumvura yekuchenesa inogona kuibvisa.
5.Charoride corrosion
Kuvapo kweimwe diki yeiyo chloride muSarufuc acid anodhonza anokwanisawo kutungamira mukugadzirisa kuora. Chitarisiko chehunhu chakadzika masalt Blay-yakavezwa makomba, ayo ari kutarisana nemapepa nemakona emakona ebasa kana mune dzimwe nzvimbo nedzimwe nzvimbo dzakakwirira dzazvino densities. Nzvimbo dzinotambudza hadzina firimu rakagadzirwa, uye ubvu hwefirimu mune yakasara "nzvimbo" nzvimbo yakaderera pane kukosha kunotarisirwa. Iyo yakakwira munyu yemukati mumvura yemapepa ndiyo huru sosi yekusvibisa mukugeza.
