Kuwonongeka kwa chiwonongeko kapena kuwonongeka kwa zinthu kapena katundu wawo woyambitsidwa ndi chilengedwe. Mitundu yambiri yamadzimadzi imachitika m'malo okhala m'mlengalenga, omwe ali ndi zigawo zowononga komanso zowononga monga mpweya, chinyezi, kutentha kutentha ndi zodetsa.
Cyclic Trussion ndi chopopera chofala komanso chowononga kwambiri. Cyclic Trussion Corlossion pamwamba pa zitsulo ndi chifukwa cha maboti a chloride omwe ali pachitsulo cholumikizira cha oxidid ndi chotchinga cha chitsulo chazitsulo ndipo ma electrochemical ayambitsidwa ndi. Nthawi yomweyo, ma ions a chlorine ali ndi mphamvu zina zamafuta, zosavuta kukhala ndi ma acsorbed mu ma pores pamtunda, ming'alu yodzaza ndi oxygen mu clorth clorides pamalo okangalika.
Kuyesedwa kwa cyclic ku Cycric ndi mtundu wa mayeso a chilengedwe makamaka kugwiritsa ntchito zida za cyclic corossion kuti apange chilengedwe cha cyclic chilengedwe kuti muyesetse kukana kwa zinthu kapena zitsulo. Imagawidwa m'magulu awiri, imodzi ya chilengedwe cha chilengedwe, inayo chifukwa cha kuyeserera kwa chilengedwe cha cyclic comlation.
Kuyeserera Kwachilengedwe kwa Cyclic Prosoling ndikogwiritsa ntchito zida zina zoyeserera zapamwamba - chipinda cha cyclic cordic to.
Amayerekezeredwa ndi chilengedwe, kusamalira mchere cha cyclide ya chilengedwe chake cha cyclic chilengedwe chomwe chimapezeka kwambiri, kuti chiwonongeko cha cyclion chikuwonjezeka, nthawi yopeza zotsatirazi zimafupikitsidwanso kwambiri. Monga mu chilengedwe chachilengedwe cha mayeso zitsanzo za malonda, kuti chilengedwe chake chitha kutenga chaka chimodzi, mukamangoyerekeza ndi nthawi yayitali.
Labotale scholated cyclic cycric itha kugawidwa m'magulu anayi
(1)Kuyesa kwa cyclic cyclionndi njira yoyeserera yoyeserera yomwe idawoneka koyambirira ndipo pakadali pano ikugwiritsidwa ntchito kwambiri. Imagwiritsa ntchito 5% sodium chloride saline yankho, yankho la PH Mtengo wosinthidwa (6.5 ~ 7.2) ngati yankho la kupopera mbewu mankhwalawa. Kutentha koyesedwa kumatengedwa 35 ℃, kuchuluka kwa zigawo za cyclic coorrossion mu 1 ~ 2ml / 80cm / h.
(2)Acetic Acid Cyclic Test (mayeso a bulu)imapangidwa pamaziko a mayeso a cyclic cyclion. Ndikuwonjezera acetic actic a actic chloride njira yothetsera mavuto a 3, kuti yankho likhale la acidic, ndipo mapangidwe a cycric Trust cycrion to acid. Mlingo wake wamiseche umakhala pafupifupi katatu kuposa mayeso a NSS.
(3)Mchere wamkuwa umathandizira acetic acid cyclion chiyeso (mayeso a cass)ndi kuyesedwa kwadzidzidzi kwatsopano kumene, kutentha kwa 50 ℃, kutentha yankho laling'ono la mchere wamkuwa - lamkuwa lamkuwa - mkuwa chloride, chipongwe cholimba kwambiri. Kukula kwake kumakhala pafupifupi 8 kamene kamayesedwa kwa NSS.
(4)Kusintha kwa ma cyclic corossionNdi mayeso okwanira a Cyclion, omwe ndi mayeso a cyclic cyclion kuphatikiza chinyezi komanso mayeso otentha. Zimagwiritsidwa ntchito makamaka pa mtundu wonse wa zinthu, kudzera mu gawo lonyowa, kotero kuti chilengedwe cha cyclic chimangopangidwa pamtunda wa malonda, komanso mkati mwa malonda. Ndichinthu chomwe chimapezeka mu cyclic chilengedwe komanso kutentha kwachilengedwe kwa chilengedwe, ndipo pamapeto pake werengani katundu wamagetsi ndi makina onse omwe ali nawo kapena osasintha.
Zotsatira zoyeserera za kuyesa kwa cyclic corossion nthawi zambiri kumaperekedwa m'malo mongopanga njira yochulukitsa. Pali njira zinayi zachipembedzo.
①Muyezo WoweruzaNdi malo okhalamo ndi malo onse a kuchulukana malinga ndi njira inayake yogawa m'magawo angapo, kwa gawo lina monga chiweruziro choyenerera, ndioyenera kuwunika kwathyathyathya.
②Kuyeza Njira YoweruzaKupitilira kulemera kwa chimbudzi chisanachitike komanso pambuyo pa kuyesa kwa kuchuluka kwa kuchuluka kwa kuchuluka kwa kututa kwa kutukudwa kwa chiwonetsero chazomwe chizolowezi, chimakhala choyenera kuwunika kwachitsulo.
③njira yoyeserera yoyesereraNjira yotsimikizika yotsimikizika, kaya ndi Cycric Trussion, kaya chinthu chimatulutsa chizolowezi cha Phenomenon kuti mudziwe zitsanzo zomwe zimagwiritsidwa ntchito kwambiri mwanjira imeneyi.
④Njira ya data yazosakanizaAmapereka kapangidwe ka zoyeserera, kusanthula kwa deta yazomwe zimayambitsa chitsimikizo cha njirayi, yomwe imagwiritsidwa ntchito posanthula, m'malo otupa, m'malo motengera kuweruza kwapadera.
Kuyesa kwa Cyclic ku Cyrosion kwa chitsulo chosapanga dzimbiri
Kuyesa kwa Cyclic Corossion kunapangidwa m'zaka za zana la makumi awiri, ndikugwiritsa ntchito nthawi yayitali ", mayesero ogwirizana kwambiri ogwiritsa ntchito, wakhala mayeso" oyenda padziko lonse lapansi. Zifukwa zazikuluzi ndi izi motere: ① kupulumutsa nthawi; Mtengo wotsika; Itha kuyesa zinthu zosiyanasiyana; Zotsatira zake ndizosavuta komanso zowoneka bwino, zabwino kukhazikika pamikangano yamalonda.
Pochita izi, kuyesedwa kwa cyclikos ku zosapanga dzimbiri ndikomwe zimadziwika kwambiri - kodi ndi maora angati omwe amayeserera pa nthawi ya cyclic ija? Akatswiri sayenera kukhala mlendo pafunso ili.
Ogulitsa zakuthupi nthawi zambiri amagwiritsa ntchitochitagasiChithandizo kapenaSinthani kalasi yopukutira, etc., kukonza nthawi yoyeserera ya cyclion ya nthawi yachitsulo chosapanga dzimbiri. Komabe, chinthu chofunikira kwambiri chofunikira kwambiri ndicho kapangidwe kanthawi yokhayokha, mwachitsanzo, chromium, molybdenum ndi nickel.
Zokwera kwambiri ndi zinthu ziwirizi, Chromium ndi Molybdenum, wamphamvu zokongoletsa zomwe zimafunikira kuti mupewe zoponyera komanso zotchinga kutukula. Kutsutsa kumeneku kumafotokozedwa malinga ndi zomwe zimatchedwaKutsutsa Kukana Zofanana(Pre) mtengo: Pre =% cr + 3.3 x% mo.
Ngakhale nickel siyikuwonjezera kukana kwachitsulo kuti idutse ndi crevice kuturuka, imatha kuchepetsa kwambiri kuchuluka kwa zotupa pambuyo poyambitsa. Nickel-yokhala ndi zosapanga dzimbiri zosakhazikika chifukwa cha mayeso a cyclitition, ndipo ndewu kwambiri kuposa zitsulo zotsika kwambiri kuposa zomwe zimachitika
Trivia: Pazigawo za 304, zopanda pake za cyclion nthawi zambiri zimakhala pakati pa maola 48 ndi 72; Pazikhalidwe za 316, kugwiritsidwa ntchito kwa cyclic cyclion nthawi zambiri pakati pa 72 ndi 120.
Ziyenera kudziwika kutiaCyclicKuyesa kumakhala ndi zovuta zazikulu poyesa kupangira chitsulo chosapanga dzimbiri.Zolemba za chloric ku Cyclion ku Cyclion kuyesa kwambiri kwa cyclion ndizokwera kwambiri, mopitilira malo okhala osapanga dzimbiri chomwe chingakane ndi zomwe zimagwiritsidwa ntchito poyeserera kwa cyclic.
Kuyesedwa kwa Cyclic ku Cyclion kumasintha machitidwe achitsulo chopanda dzimbiri, sichingawoneke ngati kuyesa kapena kuyesa kwa. Zotsatira zake ndi mbali imodzi ndipo ilibe ubale wofanana ndi magwiridwe enieni a chitsulo chosapanga dzimbiri chomwe chimagwiritsidwa ntchito.
Chifukwa chake titha kugwiritsa ntchito kuyeserera kwa cyclic kutulutsa kufanizira kuchuluka kwa mitundu yosiyanasiyana ya chitsulo chosiyanasiyana cha mbewa, koma kuyesaku kumatha kukula zinthuzo. Mukamasankha zinthu zopanda phokoso, kuyesedwa kwa cyclica kwa cyclion komwe sikunathe kuperekera chidziwitso chokwanira, chifukwa sitikumvetsetsa bwino ulalo pakati pa mayeso ndi malo ogwiritsira ntchito.
Pa chifukwa chomwechi, sizotheka kuwerengera moyo wa ntchito yongoyeserera kokha pa cyclic corluon ya zitsanzo zosapanga dzimbiri.
Kuphatikiza apo, sizotheka kupanga kufananizira pakati pa mitundu yosiyanasiyana ya chitsulo, chifukwa njira zophikira za zinthu ziwirizi zimagwiritsidwa ntchito kwambiri, ndipo kuphatikiza pakati pa ziyeso ndi malo omwe chinthucho chingafanane sichofanana.
