Anticorrosion daim ntawv thov ntawm teb kiln
Rotary kiln yog cov cuab yeej tseem ceeb tshaj plaws hauv cov cement ntau lawm, thiab nws txoj haujlwm ruaj khov yog cuam tshuam ncaj qha rau cov zis thiab qhov zoo ntawm cov cement clinker.Txawm li cas los xij, nyob rau xyoo tas los no, muaj teeb meem tsis tu ncua ntawm lub plhaub kiln, xws li deformation, tawg, thiab txawm tias tawg, ua rau muaj kev cuam tshuam ncaj qha thiab tsis ncaj, thiab txawm tias muaj teeb meem kev nyab xeeb.Muaj ntau qhov laj thawj rau cov teeb meem no, xws likev pabcuamlub sij hawm, huab cua, tus neeg teb xov tooj kev ua haujlwm, thiab lwm yam. Ib qho tseem ceeb tshaj plaws yog qhov corrosion ntawm lub tog raj kheej kheej kheej kheej kheej, uas yuav ua rau lub tog raj kheej thinner thiab txo cov kabmob muaj peev xwm, uas ua rau muaj teeb meem saum toj no.
In ntxiv rau qhov kub siab, qee yam corrosive gases kuj yuav raug tsim tawmin txheej txheem ntawm calcinkev uaclinker nyob rau hauv lub teb kiln, tshwj xeeb tshaj yog nyob rau hauv ntau lawm kab ntawm co-processing pov tseg, ib tug loj npaum li cas ntawm cov pa phem xws li sulfur oxides, nitrogen oxides, hydroxides, chlorine, thiab lwm yam..Cov pa roj no ua rau muaj tshuaj lom neeg nrog dej los tsim cov tshuaj corrosive acid-puag, uas yuav ua rau cov phab ntsa sab hauv ntawm lub qhov cub tawg.Raws li tus engineer ntawm cov cement cog, sab hauv phab ntsa ntawm lub tuam txhab lub tshuab hluav taws xob corroded los ntawm 1 hli hauv ib nrab xyoo xwb.Yog tias tsis muaj kev ntsuas los tiv thaiv corrosion, txawm tias lub tshuab hluav taws xob tshiab yuav ua rau muaj teeb meem tom qab siv ntau tshaj kaum xyoo.
Kev tiv thaiv corrosion ntawm cov phab ntsa sab hauv ntawm lub qhov cub hluav taws xob tuaj yeem siv SY-siab kub hnav-tiv thaiv-corrosion txheej.Cov yam ntxwv ntawm cov khoom no yog raws li nram no:
1. Cov txheej yog tuab, siab hardness, hnav-resistant thiab cuam tshuam-resistant, thiab tiv taus yaig los ntawm cov pa taws thiab plua plav;
2. Txheej yog resistant rau kub nruab nrab corrosion xws li sulfide, nitrogen oxide, HCl roj thiab ntsev tsuag, resistant rau "dew point" corrosion ntawm condensate dej, thiab resistant rau alternating acid thiab alkali corrosion nyob rau hauv tus txheej txheem ntawm desulfurization thiab denitrification;
3. Cov txheej txheej muaj lub neej ua haujlwm ntev thiab ua haujlwm zoo, thiab cov txheej txheej puas yooj yim kho;
4. High coefficient ntawm linear expansion, zoo adhesion, thiab muaj zog bonding quab yuam nrog lub substrate;
5. Cov thermal shock tsis kam, flue roj kub yog alternating siab thiab qis, lub txheej tsis poob, thiab tsis muaj tawg;
6. Qhov saum npoo ntawm txheej zaj duab xis yog du, nrog rau qee yam kev ntxuav tus kheej thiab tiv thaiv tar adhesion.
Nws tuaj yeem pom los ntawm cov khoom nta uas SY-siab kub hnav-tiv taus thiab tiv thaiv corrosion tsis yog tsuas yog tiv taus acid, alkali thiab kub kub, tab sis kuj muaj adhesion zoo, uas yog sib npaug rau muab ib txheej ntawm cov khaub ncaws tiv thaiv. sab hauv phab ntsa ntawm lub qhov cub rotary, uas tuaj yeem tiv taus tshuaj lom neeg thiabpkev puas tsuaj, zoo litiv thaiv lub teb kiln los ntawm corrosion puas ntawm acid thiab alkali kub.
