Corrosion ndiko kuparadzwa kana kuora kwezvinhu zvekushandisa kana zvivakwa zvavo zvinokonzerwa nenzvimbo. Kuora kwakawanda kunoitika munzvimbo dzedenga, dzine zvinhu zvinokatyamadza uye zvinhu zvakashata zvakadai seokisijeni, humidity, tembiricha shanduko uye kusanganisa.
Cyclic Corrosion yakajairika uye yakanyanya kuparadza munhukesheric corrosion. Cyclic Corrosion Corrosion pamusoro pezvematare esimbi zvinokonzerwa neiyo chloride ion in the chalkied layer uye iyo yekudzivirira yesimbi yekupinda uye yemukati yesimbi Electrochemical maitiro anokonzerwa. Panguva imwecheteyo, chlorine ion ine imwe hydration simba, zviri nyore kuti ibatwe mumapendero esimbi pamusoro, kutsiva iyo okisigine mhou, kuti tsime remamiriro ezvinhu epasi mune anoshanda.
Cyclic Corrosion Test rudzi rwekuedzwa kwemhoteredzo kunyanya vachishandisa cyclic yekuongorora bvunzo yekugadzira yekufungidzira mamiriro ekunze ekuongorora mamiriro ekugadzirisa zvinhu zvekugadzira zvigadzirwa kana zvinhu zvesimbi. Iyo yakakamurwa kuita mapoka maviri, imwe yenzvimbo yakasikwa inoratidzira bvunzo, imwe yacho yekuongorora kwekuwedzera kwekufungidzira kweiyo cyclic yekuongorora nharembozha.

Laboratori Simpord Cyclic Corrosion inogona kukamurwa kuita zvikamu zvina
(1)Neutral Cyclic Corrosion Test (nss bvunzo)is the leadlerrated test test nzira iyo yakaonekwa yekutanga uye parizvino inonyanya kushandiswa. Inoshandisa 5% sodium chloride saline solution, solution ph kukosha yakagadziridzwa mune yerudzi rwekusarerekera (6.5 ~ 7.2) semhinduro yekupfira. Iyo tembiricha yekuedza inotorwa 35 ℃, iyo yekugadzirisa iyo cyclic cyclic zvinodiwa mu 1 ~ 2ML / 80CM / h.
(2)Acetic acid cyclic corrosion test (Ass bvunzo)inovandudzwa pahwaro hwekusarerekera Cyclic Corrosion bvunzo. Iyo ndeyekuwedzera imwe glacial acetic acid mu 5% sodium chlori solution, iyo mhinduro inova acidic, uye yekupedzisira yekuumbwa kweCyclic Corrosion yakachinjawo kubva kune isina kuchena cyclic cycoros kuenda kune acidic. Rwiyo rwayo rwekukora runenge katatu nguva nekukurumidza kupfuura nss bvunzo.
(3)Copper munyu wakatsauka acetic acid Cyclic Corosion bvunzo (Cass bvunzo)Ichangobva kugadzirwa yekukudziridza kwechiitiko Cyclic Corrosion bvunzo, tembiricha yekuedza ye50 ℃, Salm Solution neine diki yemhangura yemhangura - mhangura chlorid. Rwiyo rwayo rwekukora inenge maawa masere iya yeiyo nss bvunzo.
(4)Kuchinjika cyclic corrosion bvunzoIko kwakaringana cyclic yeCycores bvunzo, iyo ndeyechokwadi yeCyclic Cyclic Cycrion test uye nguva dzose humidity uye kupisa bvunzo. Izvo zvinonyanya kushandiswa kune iyo type-mhando zvigadzirwa zvakakwana, kuburikidza nekupinda kwenzvimbo dzakanyorova, kuitira kuti iyo cyclic yeroros haina kungogadzirwa pamusoro pechigadzirwa, asiwo chiri mukati mechigadzirwa. Icho chigadzirwa muCyclic Corrosion uye vanomutsa kupisa mamiriro maviri emamiriro ekunze nenzira imwe neimwe, uye pakupedzisira kuongorora zvimiro zvemagetsi uye zvemagetsi zvechigadzirwa chose kana pasina shanduko.

Cyclic Corrosion Kuongororwa kweStanless Simbi
Muedzo weCyclic Corrosion akagadzirwa muzana remakumi maviri emakore, kushandiswa kwenguva refu kwe "bvunzo refu", kufadza kwezvinhu zvevasina kudzivisa, kwave "bvunzo" yave "muyedzo wepanyika". Zvikonzero zvikuru ndezvekutevera: ① Kuchengetedza nguva; ② mutengo wakaderera; ③ inogona kuyedza zvakasiyana siyana; ④ Mhedzisiro yacho iri nyore uye yakajeka, yakanaka yekugadzirisa kwekutengesa kukakavara.
Mukudzidzira, muyedzo weCyclic Corrosion wetsvina isimbi ndiyo inozivikanwa kwazvo - maawa mangani aya anogona kuita kuti zvinhu izvi zvingangoitika muedzo wecorosion? Varapi havafanire kuve mutorwa kumubvunzo uyu.
Vatengesi vezvevatengesi vanowanzo shandisaPassivationkurapwa kanaKuvandudza iyo Pasi Poplishing Giredhi, nezvimwe, etc., kugadzirisa iyo cyclic corrosion nguva yenguva yesimbi isina tsvina. Nekudaro, chinhu chinosemesa zvakanyanya kurumbidzwa kwesimbi yesando pachayo, kureva zvirimo zvechromium, molbdenum ne nickel.
Zvepamusoro zvemukati zvezvinhu zviviri, Chromic uye Molbdenum, iyo Simba reCorrostion Performance inodiwa kuti urambe kudzikisira uye crevice corrosion kutanga kuoneka. Uku kupokana kwecrorsion kunoratidzwa maererano neiyo inonziPamba Poting Ristance yakaenzana(Pre) kukosha: Pre =% CR + 3.3 x% mo.
Kunyangwe Nickel haawedzere kuramba kwesimbi kuti arambe uye crevico corrosion, inogona kudzora zvinobudirira kuwanda kweiyo corrostion mushure mekuita kwecrostion yatanga. Nickel-ine Austenitic Stainless Steels saka vanowanzoita zvirinani muCyclic Corrosion tests, uye corrode zvakanyanya kuderera pane yakaderera-nickel ferritic stains neyakafanana kudzikisira kuenzanisa corrosionts
Trivia: Zvekuita Standard 304, Kusarerekera Cyclic Corrosion kazhinji kuri pakati pemakumi mana nemakumi manomwe nemashanu maawa; Zvematanho 316, neakarerekera Cyclic Corrosion kazhinji iri pakati pe72 uye 120 maawa.
Zvinofanira kucherechedzwa kutithe theCyclic CorrosionKuedzwa kune ma mikuru anokanganisa kana achiedza zvivakwa zve simbi isina tsvina.Iyo chloride yezvinyorwa zveCyclic Corrosion muCyclic bvunzo yakakwirira kwazvo, saka simbi yakasarudzika iyo inogona kuenderana neyakaderera chloride ichave yakagadziriswa muCyclic bvunzo yeCyclic.
Cyclic Corrosion test inochinja maitiro ecorosion yesimbi isina tsvina, haigone kutorwa seyedzo yekuwedzera kana kuedza kwekufungidzira. Mhedzisiro yacho ndeye imwe-yakatarisana uye isina hukama hwakaenzana nekuita chaiko kwesimbi isina tsvina iyo pakupedzisira yakaiswa mukushandisa.
Saka isu tinogona kushandisa iyo cyclic bvunzo yekudyidzana kuti ienzanise kudzikisira kwemhando dzakasiyana dzemhando dzakasiyana dzesimbi, asi iyi bvunzo inongokwanisa kuyera zvinyorwa. Paunenge uchisarudza Stainless Steel zvinhu zvakananga, iyo cyclic yekudyara bvunzo yega haiwanzo kupa ruzivo rwakakwana, nekuti isu hatina nzwisiso yakakwana yechibatanidza mamiriro ezvinhu epamba uye nzvimbo chaiyo yekushandisa.
Nechikonzero ichochi, hazvigoneke kufungidzira hupenyu hwebasa rechigadzirwa hwakangobva pane yeCyclic muyedzo wetsiva wetsiva simbi isina tsvina.
Mukuwedzera, hazvigoneke kuenzanisa pakati pemhando dzakasiyana, nekuti hatigone kuenzanisa zvisina mwero netema, nekuti zvakaringana pakati pemamiriro ezvinhu akaedzwa uye iyo iyo chigadzirwa chichaguma kushandiswa kwacho hakuna kufanana.
