Ububanzi besicelo
Ifanele ukwelashwa kwe-anti-corrosion ohlangothini lwangaphakathi lomtshingo.I-Type I ilungele ukwelashwa okuqeda ukugqwala kwendawo lapho ithintana ngqo negesi ephuma ku-flue, enomkhawulo wokumelana nokushisa ongu-250 ℃ kanye ne-sulfuric acid ukumelana nokugqwala komkhawulo wama-40%.
Imiyalo yohlelo lokusebenza
Ukwelashwa Okusebenzayo Kwe-Substrate kanye Nomphezulu
1, Ukwelashwa kwe-substrate yensimbi: ukuqhunyiswa kwesihlabathi noma ukuqhunyiswa kwesibhamu ukuze kususwe ukugqwala kufinyelele ezingeni le-Sa2.5, ukuhwalala okungama-40 ~ 70um, ukuthuthukisa ukunamathela kokunamathela ne-substrate.
2,Uma usebenzisa, gudluza ingxenye A kuqala, bese wengeza ingxenye ye-ejenti elaphayo B ngokulinganayo, gudluza ngokulinganayo, gcina isikhathi sokungeniswa imizuzu eyi-15 ~ 30, lungisa i-viscosity yohlelo lokusebenzainani elifanele leumncane okhethekile ngokwezindlela zokufaka isicelo.
Izindlela zokufaka isicelo
1, Isifutho esingenamoya, isifutho somoya noma irola
I-brush ne-roller coating inconywa kuphela ngejazi lemigqa, ukumbozwa kwendawo encane noma ukuthinta phezulu.
I-2, ukujiya kwefilimu eyomile Kunconyiwe: 300um, ungqimba olulodwa lokugqoka lungaba ngu-100um.
3, Uma kubhekwa ukuthi imvelo egqwalayo inokhahlo, futhi ukungabikho kokunamathela kuzodala insimbi ukuthi igle ngokushesha, kunciphise impilo yesevisi.
ngenxa yokusetshenziswa kwendawo eyonakalisayo yefilimu yokugqoka ibe namandla kakhulu, ukuvuza kuzokwenza ukugqwala kwe-coating ngokushesha futhi kunciphise impilo yesevisi.
I-Desulfurization & denitrification device imiyalelo yohlelo lokusebenza odongeni lwangaphakathi
Ukwelashwa kwendawo
Amafutha noma amafutha kufanele asuswe ngokuya ngezinga lokuhlanza i-solvent ye-SSPC-SP-1.
Kunconywa ukufutha ukuphatha indawo yensimbi ku-Sa21/2 (ISO8501-1:2007) noma i-SSPC-SP10 ejwayelekile.
Uma i-oxidation yenzeka ebusweni ngemuva kokufafaza nangaphambi kokudweba lo mkhiqizo, khona-ke indawo kufanele iphindwe kabusha.Hlangana nezindinganiso ezibonisiwe ezicacisiwe.Ukulimala okungaphezulu okuvezwe ngesikhathi sokwelashwa kwesifutho kufanele kugaywe, kugcwaliswe, noma kuphathwe ngendlela efanele.Ubulukhuni obuphezulu obunconywayo bungama-40 kuye ku-70μm.Ama-substrates alashwa ngokuqhunyiswa kwesanti noma ngokuqhunyiswa kwesibhamu kufanele afakwe phakathi kwamahora ama-4.
Uma i-substrate ingaphathwa ngezinga elidingekayo, izobangela ukugqwala ukubuya, ifilimu yokupenda i-flaking, ukukhubazeka kwefilimu yepende ngesikhathi sokwakhiwa, njll.
Umyalelo wohlelo
Ukuxuba: Umkhiqizo uhlanganiswe nezingxenye ezimbili, Iqembu A kanye neQembu B. Isilinganiso sihambisana nokucaciswa komkhiqizo noma ilebula emgqonyeni wokupakisha.Hlanganisa kahle ingxenye engu-A nesixube samandla kuqala, bese wengeza ingxenye engu-B ngokulinganayo bese uxuba kahle.Engeza inani elifanele le-epoxy thinner, isilinganiso sokunciphisa esingu-5~20%.
Ngemuva kokuthi upende uxutshwe futhi ugoqwe kahle, ake uvuthwe imizuzu engu-10 ~ 20 ngaphambi kokufaka.Isikhathi sokuvuthwa nesikhathi esisebenzayo sizofinyezwa njengoba izinga lokushisa likhuphuka.Upende omisiwe kufanele usetshenziswe phakathi nesikhathi sokuqinisekisa.Upende oweqa isikhathi esisebenzayo kufanele ulahlwe yimfucuza futhi akufanele usetshenziswe futhi.

| Isikhawu esikhulu sokupenda | Akukho mkhawulo, uma ubuso bubushelelezi, kufanele bufakwe isihlabathi | |||
Izindlela zokufaka isicelo
Ukufafaza okungenamoya kuyanconywa ekwakhiweni kwendawo enkulu, ukufafaza komoya, ukuxubha noma ukumboza nge-roller nakho kungasetshenziswa.Uma ukufutha kusetshenziswa, ama-weld seams namakhona kufanele kupendwe kuqala, ngaphandle kwalokho, kuzodala ukumanzisa kabi kopende ku-substrate, ukuvuza, noma ifilimu kapende omncane, okuholela ekugqwaleni nasekuxebukeni kwefilimu kapende.
Misa isikhashana ekusebenzeni: Ungashiyi upende kumashubhu, izibhamu, noma izinto zokufafaza.Hlanza yonke imishini kahle nge-thinner.Upende akufanele uvalwe kabusha ngemva kokuxuba.Uma umsebenzi umisiwe isikhathi eside, kunconywa ukusebenzisa upende osanda kuxutshwa lapho uqala kabusha umsebenzi.
Izinyathelo zokuzivikela
Lo mkhiqizo uyisigqoko esikhethekile sokulwa nokugqwala kodonga lwangaphakathi lwedivayisi ye-desulfurization kanye ne-denitrification, indawo engezansi iwuhlobo olulodwa, olunokumelana okuphezulu kwe-abrasion, ukumelana okuhle kwe-asidi (40% sulfuric acid), kanye nokumelana okuhle kokushintsha kwezinga lokushisa.Ngesikhathi sokwakha, isibhamu sokufutha, ibhakede likapende, ibhulashi lokupenda, nerola akufanele kuhlanganiswe, futhi izinto ezipendwe ngalo mkhiqizo akufanele zingcoliswe nabanye opende abavamile.
Ukuhlolwa kwefilimu yokugqoka
a.Ibhulashi, i-roll, noma isifutho kufanele ifakwe ngokulinganayo, ngaphandle kokuvuza.
b.Ukuhlolwa kokuqina: ngemuva kwesendlalelo ngasinye sikapende, hlola ubukhulu, ngemuva kokuthi wonke upende kufanele uhlole ubukhulu befilimu kapende, amaphuzu okulinganisa ngokuya ngamamitha-skwele ayi-15, 90% (noma 80%) amaphuzu akaliwe ayadingeka. finyelela inani lokujiya elicacisiwe, futhi ukujiya okungafinyeleli inani elishiwo akumele kube ngaphansi kuka-90% (noma u-80%) yenani elishiwo, ngaphandle kwalokho upende kufanele lupendwe kabusha.
c.Ubukhulu obuphelele bokugqoka kanye nenani leziteshi zokugqoka kufanele kuhlangabezane nezidingo zokuklama;indawo engaphezulu kufanele ibe bushelelezi futhi ingabi namamaki, ihambisane nombala, ingabi namaphinifa, amabhamuza, igeleze phansi, futhi inqamuke.
d.Ukuhlolwa kokubukeka: Ngemuva kokwakhiwa ngakunye kopende, ukubukeka kufanele kubhekwe, kubhekwe ngeso lenyama noma ingilazi yokukhulisa izikhathi ezi-5, futhi izimbobo, ukuqhekeka, ukuxebuka, nokuvuza kopende kufanele kulungiswe noma kupendwe kabusha, futhi inani elincane lokugeleza lilenga. kuvunyelwe ukuba khona.Izidingo eziqondile zekhwalithi yokumboza zimi kanje:
| Izinto zokuhlola | Izimfuneko zekhwalithi | Izindlela zokuhlola |
| Ukucwecwa, ukuvuza kwebhulashi, ukugqwala kwepani, nokungena phansi | Akuvunyelwe | Ukuhlola okubonakalayo |
| Iphinikhodi | Akuvunyelwe | 5~10x ukukhulisa |
| Isikhumba esigelezayo, esishwabene | Akuvunyelwe | Ukuhlola okubonakalayo |
| Ukomisa ukujiya kwefilimu | Hhayi ngaphansi kobukhulu bomklamo | Izikali zikaMagnetic Thickness |
Imibandela yohlelo lokusebenza nemikhawulo
Izinga lokushisa le-ambient ne-substrate:5-40 ℃;
Okuqukethwe kwamanzi kwe-substrate:<4%<br/>Umswakama womoya ofanelekile:Umswakama ohlobene ofika ku-80%, imvula, inkungu, nezinsuku zeqhwa azikwazi ukwakhiwa.
Indawo yamazolo:Izinga lokushisa elingaphezulu kwe-substrate lingaphezu kuka-3 ℃ ngaphezu kwendawo yamazolo.
Uma lakhiwe ngaphansi kwemvelo engahlangabezani nezimo zokwakha, ukunamathela kuzofinyela futhi kwenze ifilimu likapende liqhakaze, ibhamuza, nokunye ukonakala.
Lo mkhiqizo awumelani nokukhanya kwe-ultraviolet, ngakho-ke kunconywa ezindaweni zasendlini.
Izinyathelo zokuphepha
Lo mkhiqizo kufanele usetshenziswe endaweni yokukhiqiza ngabaqhubi bemidwebo abangochwepheshe ngaphansi kwale manuwali yeziqondiso, ishidi ledatha yokuphepha okubalulekile, kanye nemiyalelo esesitsheni sokupakisha.Uma leli Shidi Ledatha Yezokuphepha Ezibalulekile (MSDS) lingafundiwe;lo mkhiqizo akufanele usetshenziswe.
Konke ukumbozwa kanye nokusetshenziswa kwalo mkhiqizo kumele kwenziwe ngaphansi kwazo zonke izindinganiso nemithetho kazwelonke efanele yezempilo, ukuphepha, kanye nemvelo.
Uma ukushisela noma ukusika amalangabi kuzokwenziwa ngensimbi eboshwe ngalo mkhiqizo, kuzokhishwa uthuli, ngakho-ke imishini yokuzivikela efanelekile kanye nokukhipha umoya okwanele kwendawo kuyadingeka.
Isitoreji
Ingagcinwa okungenani izinyanga eziyi-12 ezingeni lokushisa elingu-25°C.
Ngemuva kwalokho kufanele ihlolwe futhi ngaphambi kokusetshenziswa.Gcina endaweni eyomile, enomthunzi, kude nemithombo yokushisa neyomlilo.
Isimemezelo
Ulwazi olunikezwe kuleli bhukwana lusekelwe elabhorethri yethu nolwazi olusebenzayo futhi luhloselwe njengesithenjwa kumakhasimende ethu.Njengoba izimo zokusetshenziswa komkhiqizo zingaphezu kwamandla ethu, sinikeza kuphela isiqinisekiso sekhwalithi yomkhiqizo ngokwawo.
