Mushure mekunge Chengshuo Hardware mechanical mainjiniya apedza kunyatsogadzira uye prototype saizi yekuyedza zvigadzirwa zvesimbi, dhipatimendi redu rekugadzirisa zvigadzirwa richaita zvakanatswa mushure mekugadzirisa zvigadzirwa zvesimbi zvinoenderana nenharaunda umo vatengi vanoshandisa zvigadzirwa zvesimbi.
Vanhu vazhinji vanofunga nezvekurapa kwepamusoro, uye vanogona kungozvitora senge pendi uye poda coating kuita kuti zvikamu zviwedzere kunaka uye kuchinja ruvara.Muchokwadi, kurapwa kwepamusoro hakungori kweaesthetics.Kurapa kwakasiyana-siyana kwepamusoro kunobata kunze kwezvigadzirwa zvesimbi nekuisa yakatetepa yekuwedzera layer pamusoro.Kurapa kwakakodzera kwepamusoro kunogona kubatsira mhando dzakasiyana dzesimbi dzakagadziriswa zvigadzirwa kugamuchira zvirinani kuchengetedzwa munzvimbo yekushandiswa (senge corrosion resistance, kudzikisira ngura), kuchengetedza zvigadzirwa zvesimbi, uye kuzadzisa chinangwa chekuwedzera hupenyu hwesevhisi.
Nhasi tichakuzivisai kugadzirwa kwealuminium chigadzirwa uye kurapwa kwepamusoro, anodizing, iyo Chengshuo Hardware inonyanya hunyanzvi.
Chii chinonzi anodizing?
Anodizing inzira ye electrochemical inoshandura nzvimbo yesimbi kuita yekushongedza, yakasimba, uye isingadziviriri anode oxide pamusoro.Aluminium yakanyatsokodzera anodizing, kunyangwe mamwe masimbi asina-ferrous akadai se magnesium uye titanium anogona zvakare anodized.
Muna 1923, anodizing yakatanga kushandiswa pachiyero cheindasitiri kuchengetedza aluminium zvikamu zvendege dzegungwa kubva pakuora.Mumazuva ekutanga, chromic acid anodizing (CAA) ndiyo yaive nzira yaifarirwa, dzimwe nguva inonzi Bengough Stuart process, sekutsanangurwa kwazvinoitwa muUK Defense Specification DEF STAN 03-24/3.
Ikozvino yakakurumbira classification ye anodizing
Anodizing yakashandiswa zvakanyanya mumaindasitiri kwenguva yakareba.Kune nzira dzakawanda dzekushandisa mazita akasiyana, uye kune akati wandei nzira dzekuisa dzinogona kupfupikiswa sezvizvi:
Yakarongedzwa nemhando yemazuva ano: DC anodizing;AC anodizing;Uye pulse ikozvino anodizing, iyo inogona kupfupisa nguva yekugadzira kuti iwane ukobvu hunodiwa, ita iyo firimu layer yakakora, yunifomu uye dense, uye zvakanyanya kunatsiridza kusaonda.
Zvinoenderana neiyo electrolyte, inogona kukamurwa kuita sulfuric acid, oxalic acid, chromic acid, yakasanganiswa asidhi, uye yakasikwa mavara anodic oxidation ine sulfonic organic acids semhinduro huru.Oxalic acid anodizing yaive patented muJapan muna 1923 uye yakazoshandiswa zvakanyanya muGermany, kunyanya mumashandisirwo ekuvaka.Anodized aluminium oxide extrusion chaive chivakwa chakakurumbira muma1960 nema1970, asi chakazotsiviwa nemapurasitiki akachipa nehupfu.Yakasiyana-siyana phosphoric acid maitiro ndechimwe chezvazvino kuitika mukutanga kurapwa kwearuminiyamu zvikamu zvinoshandiswa kusungirira kana kupenda.Kuchinja kwakasiyana kwakaoma muanodic oxidation process uchishandisa phosphoric acid ichiri kubuda.Maitiro echiuto uye maindasitiri zviyero ndeyekurongedza anodizing maitirwo anoenderana nekubatisa maitiro mukuwedzera kune yekuziva process chemistry.
Zvinoenderana nehunhu hweiyo firimu layer, inogona kukamurwa kuita: yakajairika firimu, yakaoma firimu (yakakora firimu), ceramic firimu, inopenya gadziriso layer, semiconductor barrier layer, nezvimwe zveanodizing.
Kurongeka kweAnodizing Maitiro eAluminium Zvigadzirwa
Anodizing process dzimwe nguva inoshandiswa kufumura (isina coated) aruminiyamu yakagadzirwa kana makemikari akagayiwa zvikamu zvinoda anti-corrosion dziviriro.Anodic machira anosanganisira chromic acid (CAA), sulfuric acid (SAA), phosphoric acid, uye boric acid sulfuric acid (BSAA) anodizing maitiro.Iyo anodizing process inosanganisira electrolytic kurapwa kwesimbi, iyo yakagadzikana firimu kana coating inoumbwa pamusoro pesimbi.Anodic coatings inogona kuumbwa pane aruminiyamu alloys mune akasiyana maelectrolyte uchishandisa angave alternating ikozvino kana yakananga ikozvino.
Anodizing inowanikwa nekunyudza aruminiyamu mune acidic electrolyte bath uye kupfuura ikozvino kuburikidza nepakati.Iyo cathode yakaiswa mukati meanodizing tank;Aluminium inoshanda seanode, inoburitsa maion eokisijeni kubva mu electrolyte uye inosunga kumaatomu ealuminium pamusoro pechikamu cheanodized.Naizvozvo, anodizing inodzoreka zvakanyanya oxidation inosimudzira zvakasikwa zviitiko.
Anodization inosanganisira Type I, Type II, uye Type III.Anodizing ndeye electrolytic passivation process inoshandiswa kuwedzera ukobvu hweyakasikwa oxide layer pamusoro pezvikamu zvealuminium.Aluminium components are anodized (saka inonzi "anodizing"), uye ikozvino inoyerera pakati payo uye cathode (kazhinji flat aluminium rod) kuburikidza ne electrolyte yambotaurwa (inowanzo sulfuric acid).Basa guru reanodizing nderekuwedzera corrosion resistance, kupfeka kuramba, kunamatira pendi uye primer, nezvimwe.
PIC naCorlee:Rudzi IIIanodized aluminium zvikamu
Iyo anode oxide chimiro inotangira kubva kualuminium substrate uye inoumbwa zvachose nealuminium oxide.Rudzi urwu rwealuminium harushandiswe kumusoro sependi kana machira, asi yakanyatsobatanidzwa neiyo pasi pealuminium substrate, saka haizopwanyike kana kupepeta.Iyo ine yakanyatso kurongeka porous chimiro uye inogona kuiswa kune yechipiri kugadzirisa senge coloring uye chisimbiso.
