I-Sorision yintshabalalo okanye ukonakaliswa kwezinto okanye iipropathi zabo ezibangelwa yindalo. Uninzi losulelo lwenzeka kwiindawo ezinemimoya, equka izinto ezonakalisayo kunye nemiba ebonakalayo efana neoksijini, umswakama, utshintsho lobushushu kunye nokungcolisa.
I-Cyclic Solrosion yinto eqhelekileyo kwaye eyonakalisayo ye-themospicic. I-Cyclic Solclion Soutorion Porrosion kumphezulu wezinto zensimbi ngenxa ye-chloride iqulethe umphezulu we-oxided ye-oxided ye-oxided kunye ne-owrochemical yensimbi yensimbi ebangelwa. Kwangelo xesha, i-chlorine i-ions iqukethe amandla athile omzimba, kulula ukubekwa kwi-pores yomphezulu wensimbi, i-rocks ihluthwe ioksijini, i-axiden inkcitho ibe yi-chloride, ukuze idluliselwe imeko yomphezulu.
Uvavanyo lweCycclic South Lokoma kuvavanyo lokusingqongileyo ikamva lokusingqongileyo lusebenzisa izixhobo zovavanyo lweSyclic Socicial Ukudala ukwenziwa kweemveliso zeCyclic Sociection Ukuvavanya ukunganyangeki kwemveliso okanye izinto zentsimbi. Yahlulahlulwe yangamanqanaba amabini, enye yendalo yokubonisa ukuvezwa kwendalo, enye yokukhawulezisa ukuvavanywa kwemeko yendalo eshukumayo.
Ukulinganisa ukufakwa kokuhlola ukuvavanywa kokusingqongileyo ngoCwangciso kukusetyenziswa kwesixhobo esithile sovavanyo lweemvavanyo - igumbi lokuvavanya i-Cyclic Social (umzobo), kumthamo wendawo ehamba-hlukeneyo yokuvavanya umgangatho wokunganyangeki kwemveliso yokuhamba kwemveliso.
Kuthelekiswa nendawo yendalo, ityuwa yetyuwa yendawo yayo yokuhamba nge-cyclic yendalo esingqongileyo, ukuze inqanaba le-corrosion linyuswe kakhulu, ixesha lokufumana iziphumo lifutshane kakhulu. Enjengokwimeko yokuvezwa kwendalo yovavanyo lwesampulu yemveliso, ukubakho kunokuvela kunokuthatha unyaka omnye, ngelixa kulungiselelwe ukwenziwa kweemeko zokusingqongileyo ngokusingqongileyo, kangangeeyure ezingama-24, unokufumana iziphumo ezifanayo.
I-Labhoratri eyenziwe yelebhu ye-cyclic inokwahlulwa zangamacandelo amane
(1)Uvavanyo lweChyclion Conrosion Corrosion (i-NSS yovavanyo)Yindlela yokuvavanya okukhawulezileyo yokubona oko kwabonakala okokuqala kwaye okwangoku isetyenziswe kakhulu. Isebenzisa i-5% ye-sodium ye-sodium cheride, ixabiso le-PH lihlengahlengiswe kuluhlu olungathathi hlangothi (6.5 ~ 7.2) njengesisombululo sokutshiza. Iqondo lobushushu lovavanyo lithathwa i-35 ℃, inqanaba lokuhlaliswa kwemfuno zeCyclic Social Resosion kwi-1 ~ 2ml / 80cm / h.
(2)I-Acetic Acid Cyclion Conrosion yovavanyo (uvavanyo lwe-AS)iphuhliswa kwisiseko sovavanyo lwehlango lokucoca uCyclic. Kuyongeza i-acid ye-acid ye-GOLIT kwi-5% yesodium chloride, ukuze ixabiso le-PH lincitshisiwe liye lancitshiswa malunga ne-3, isisombululo sitshintshiwe kwi-acidic ye-cyclic ikwatshintshwa kwi-acidic. Ireyithi yophawu lwayo malunga namaxesha ama-3 ngokukhawuleza kunovavanyo lwe-NSS.
(3)I-Copper i-Colper itshixiwe i-acetic acid ye-acid yovavanyo lwe-Acivic Syccia (CASSS)Uvavanyo olutsha olusandul 'ukwenziwa kwamanye amazwe, ubushushu bovavanyo lwe-50 ℃, isisombululo setyuwa ngesixa esincinci setyuwa yobhedu - i-pherper chloride, ikhutshiwe. Ireyithi yophawu lwayo malunga namaxesha ama-8 ovavanyo lwe-NSS.
(4)Enye i-Cyclion Conrosion Corrosionluvavanyo olubanzi lweCycclion Corrosion, enamahlathi e-Cyclic Solclion School kunye novavanyo lobushushu kunye novavanyo lobushushu. Isetyenziselwa ikakhulu i-cavity-uhlobo lweemveliso, ngokusebenzisa impahla yendawo enomswakamkileyo, ukuze i-cyclion yosulelo ayivelisi kuphela kumphezulu wemveliso, kodwa ngaphakathi kwemveliso. Yimveliso kwi-cyclic yolonwabo kwaye uthobe ubushushu beemeko ezimbini zokusingqongileyo ngokuthe ngqo, kwaye ekugqibeleni zivavanye iipropathi zombane kunye noomatshini bemveliso yonke okanye ngaphandle kotshintsho.
Iziphumo zovavanyo zokuvavanywa kokuzonwabisa nge-Syclic zinikezelwa ngokubanzi kunendlela yobungakanani. Kukho iindlela ezine zomsebenzi.
①Indlela yokugwebayindawo yokulungela kunye nendawo iyonke yomyinge wepesenti ngokwendlela ethile yokwahlulahlulahlulo lwamanqanaba aliqela, ukuya kwinqanaba elithile njengesigwebo esifanelekileyo, kufanelekile ukuba kuvavanywe.
②Indlela yokugwebaKubunzima besampulu ngaphambi nasemva kwexesha lokulinganisa lokulinganisa, ukubala ubunzima bokuphulukana nokususwa komgangatho wokunganyangeki kwesampulu yokunganyangeki.
③Indlela yokuchazelaYindlela yokuzimisela, yivavanyo lokungahambisi ngoCycclic, nokuba imveliso ivelisa i-phenomenon yokufumanisa isampulu, imigangatho yemveliso jikelele isetyenziswa kakhulu kule ndlela.
④Indlela yohlalutyo lweenkcukacha zohlalutyo lweenkcukachaInika uyilo lovavanyo loKhenketho, uhlalutyo lwedatha yokulwa, idatha yolonwabo ukumisela inqanaba lokuzithemba le ndlela, esetyenziselwa ukuhlalutya ukuhlalutya, kunokukorakosi, kunokuba kuqondwe ngokomgangatho wemveliso.
Ukuvavanywa kwe-cyclic yokuvavanywa kwentsimbi engenasitali
Uvavanyo lweCycclic Sorection lwangelwe kwinkulungwane yamashumi amabini, yeyona nto iphambili kuvavanyo "lovavanyo lwe-Intersion", i-Socioresion yeNdawo yokuHlala-enganyangekiyo, iye yaba luvavanyo "luthini". Ezona zizathu ziphambili zezi zilandelayo: Ukonga ixesha; ② Ixabiso eliphantsi; ③ unokuvavanya iintlobo ezahlukeneyo; Iziphumo zilula kwaye zicacile, zintle kukuhlaliswa kweembambano zorhwebo.
Xa uziqhelanisa, uvavanyo lwe-cycclic lolonwabo lwensimbi engenazibala lelona lubalulekileyo- zingaphi iiyure ezinokufumana? Iingcali akufuneki zibengesisemzini kulo mbuzo.
Abathengisi bezinto eziphathekayo bahlala besebenzisaidluleunyango okanyeUkuphucula iBakala lokuposa ngaphezulu, njl. Nangona kunjalo, eyona nto ibaluleke kakhulu yokuzimisela kukwenziwa kwensimbi engalunganga, okt umxholo we-chromium, molybdenum kunye ne-nickel.
Ukuphakama komxholo wezinto ezimbini, iChromium kunye ne-molybdenum, eyomeleleyo kakhulu intsebenzo efunekayo yokuxhathisa i-wit kunye ne-Crevice yosulelo. Ukuchasana nokuchasana kubonakalisiwe ngokwendlela ebizwa ngokuba yiyoUkulinganisa ukumelana(Ngaphambi) Ixabiso: Ngaphambi =% cr + 3.3 x% mo.
Nangona i-nickel ayiphumi ukuxhathisa intsimbi yokuqina kunye nokuntywila kweKrevice, inokucothi kakuhle inqanaba emva kwenkqubo yokungasebenzi sele iqalile. I-nickel-eneziqwenga ezingenasiseko ze-Austititic ke ngoko zidla ngokwenza ngcono iimvavanyo zokuzonwabisa ngokuhamba kwexesha, kwaye zikhule kakhulu kunee-nickel ze-pickel ze-pickel ze-picricric.
I-Trivia: Ngokubalisa i-304, ukungathathi hlango-cyclic ucocekile ngokubanzi phakathi kweeyure ezingama-48 nezingama-72; Ngomgangatho wama-316, ukungathathi hlango-cyclic ucocekile ngokubanzi phakathi kweeyure ezingama-78 ukuya kwe-120.
Kufuneka iqatshelwe ukubaiI-Cyclic SolrosionUvavanyo luneembaleki ezinkulu xa kuvavanywa iipropathi zensimbi engenasiseko.Umxholo we-chloride we-Cyclic Solcoion kwi-Cyclic Sociorion uphakame kakhulu, kude kakhulu kwindawo yokwenyani, ngoko ke intsimbi engenasiseko enokuyichaphazela imeko ye-chloride ye-chlorilion iya kutyunjwa kuvavanyo lwe-cyclic lolonwabo.
Uvavanyo lweCycclic Sorection lutshintsha indlela yokuziphatha kwentsimbi engenasinye, ayinakuthathwa njengovavanyo olukhawulezileyo okanye ulingo lokulinganisa. Iziphumo zikwicala elinye kwaye azinalo ubudlelwane obulinganayo kunye nokwenzakala kwentsimbi engenasibala ekufuneka isetyenziswe.
Ke sinokusebenzisa uvavanyo lweCyclic South TOVION ukuthelekisa ukunganyangeki kweentlobo ezahlukeneyo zentsimbi engenasibala, kodwa olu vavanyo lunamandla okulinganisa umxholo. Xa ukhetha izixhobo zentsimbi ezingenakwenzeka ngokuthe ngqo, uvavanyo lwe-cyclic lodwa aluhlali lubonelele ngolwazi olwaneleyo, kuba asinalo ulwazi olwaneleyo lonxibelelwano phakathi kweemeko zovavanyo kunye nemeko yesicelo.
Ngesizathu esinye, akunakwenzeka ukuqikelela ubomi benkonzo yemveliso esekwe kuphela kuvavanyo lwe-cyclic lolonwabo lwesampulu yentsimbi engenanto.
Ukongeza, akunakwenzeka ukuba uthelekiso phakathi kweentlobo ezahlukeneyo zentsimbi, umzekelo, asinakuthelekisa intsimbi engenasitali kunye neendlela zokunxibelelana ezisetyenzisiweyo, kwaye eyona ndawo izakugqitywa kuyo ayifani.
