1. Izidingo zobuchwepheshe zokudweba umkhumbi
Ingxenye eyinhloko kapende omelene nokugqwala ifilimu ye-anti-rust pigment box forming, iwuhlobo lokumboza ukuvikela ingaphezulu lensimbi emoyeni, emanzini, njll., noma ukugqwala kwe-electrochemical.Upende we-Antirust uhlukaniswe ngopende we-antirust ngokomzimba namakhemikhali izigaba ezimbili.Imibala engokoqobo nopende bakha ifilimu ukuze kuvinjelwe ukuhlasela kwezinto ezonakalisayo, njengopende obomvu wensimbi, upende ovimbela ukubola kwe-graphite, njll. Amakhemikhali avimbela ukugqwala kwamakhemikhali ombala wokugqwala ukuze avimbele ukugqwala, njengomthofu obomvu, upende ophuzi ophuzi ovimbela ukugqwala.Ngokuvamile esetshenziswa ehlukahlukene Bridges, imikhumbi, amapayipi zasendlini kanye nokunye ukuvimbela nokugqwala metal.
2. Izindinganiso zokwakha zopende womkhumbi
Ukufafaza ngomkhumbi kuvame ukusetshenziswa ngokufafaza okungenamoya wokucindezela okuphezulu, le ndlela yokwakha upende wobuchwepheshe obuphezulu ibhekisela ekusetshenzisweni kopende wokufafaza ocindezelayo, upende endaweni yokukhipha umlomo uphoqeleka ukuba u-atomize, ufafaze phezu kwengubo ukuze wenze upende. ifilimu.Uma kuqhathaniswa nendlela yokufafaza, ukusetshenziswa kopende wokufafaza okungenamoya ondizayo kancane, ukusebenza kahle okuphezulu futhi kungenziwa kuhlanganiswe nefilimu ewugqinsi, ngakho-ke ifaneleka ngokukhethekile isicelo sokwakhiwa kwendawo enkulu.Kodwa ukunakwa kufanele kukhokhwe ekuvimbeleni umlilo lapho usebenzisa ukufutha okungenamoya.Ngakho-ke, umshini wokufafaza ongenawo umoya womfutho ophezulu we-pneumatic usube yinketho yokuqala yokufuthwa kweMarine.Njengamanje, cishe zonke izikhungo zemikhumbi zisebenzisa lo mshini lapho zipenda izindawo ezinkulu.
3. Umshini wokufafaza onconyiwe ofanele ukufafaza kwasolwandle
I-HVBAN yethule i-HB310/HB330/HB370 yochungechunge lomshini wokufutha womoya.Yakhelwe eduze nokuhamba nokusebenza okuphezulu, lo mugqa ongabizi kakhulu wemishini yokufafaza yomoya ungumphelelisi ophelele weqembu ngalinye lokufafaza lasoLwandle.
Lezi zifutho ezifakazelwe futhi ezihlala isikhathi eside zilungele ivolumu ephezulu kanye nengcindezi ephezulu engangeni manzi, ukumelana nomlilo kanye nezicelo zopende ezivikelayo, ezinikeza ukunethezeka okukhulu kanye nenani kubo bonke osonkontileka.
4. Ubuchwepheshe bokwakha upende womkhumbi
Umkhumbi uzopendwa ngezingqimba eziningana zopende ophikisana nokugqwala, i-primer, upende ongaphezulu kanye nopende wamanzi ocacile.Abahlinzeki bepende yemikhumbi ngokuvamile bathumela abasebenzi ukuze banikeze isiqondiso sobuchwepheshe endaweni yokwakha, futhi izidingo zopende zihlukile ezindaweni ezihlukene kanye nomswakama ohlukile.
5. Imininingwane yokudweba umkhumbi
Upende womkhumbi uwuhlobo lopende olungafakwa phezu komkhumbi.Inhloso eyinhloko yokupenda komkhumbi ukukhulisa impilo yesevisi yomkhumbi futhi uhlangabezane nezidingo ezihlukahlukene zomkhumbi.Upende womkhumbi uhlanganisa upende ovimbela ukungcola ongaphansi komkhumbi, upende wethangi lamanzi okuphuza, upende owomile wethangi lempahla kanye nabanye opende.Okulandelayo sizoqonda izici zopende we-Marine kanye nenqubo yokumboza.
6.1 Izici zopende lomkhumbi
Ubukhulu bomkhumbi bunquma ukuthi upende lomkhumbi kufanele lukwazi ukomisa ekamelweni lokushisa.Upende odinga ukushiselwa futhi womiswe awufanele upende wasolwandle.Indawo yokwakha yepende ye-Marine inkulu, ngakho-ke upende kufanele ulungele ukusebenza komshini wokufafaza okungenamoya.Ukwakhiwa kwezinye izindawo zomkhumbi kunzima, ngakho-ke kuthenjwa ukuthi umdwebo ungafinyelela ubukhulu befilimu obuphakeme, ngakho upende wefilimu owugqinsi uvame ukudingeka.Izingxenye ezingaphansi kwamanzi zomkhumbi zivame ukudinga ukuvikelwa kwe-cathodic, ngakho-ke upende osetshenziselwa izingxenye ezingaphansi kwamanzi ze-hull udinga ukuba namandla okuhle ukumelana nokumelana ne-alkaline.Amafutha - asekelwe noma amafutha - upende oguquliwe kulula ukwenza i-saponification futhi awufaneleki ukwakhiwa kopende ngaphansi komugqa wamanzi.Imikhumbi ngokombono wokuphepha komlilo, ingaphakathi legumbi lenjini, upende wangaphakathi we-superstructure akulula ukuwushisa, futhi uma ukuvutha ngeke kukhiphe intuthu eyeqile.Ngakho-ke, upende we-nitro nopende wenjoloba one-chlorine awufanele upende womhlobiso wekhabethe lomkhumbi.
6.2 Izidingo zenqubo yokumboza ngopende womkhumbi
1. Iphaneli yangaphandle ye-Hull, iphaneli yedekhi, iphaneli ye-bulkhead, i-bulwboard, iphaneli yangaphandle ye-superstructure, iphansi elingaphakathi kanye namaphrofayili ayinhlanganisela namanye amaphaneli angaphakathi, ngaphambi kokuthulula kusetshenziswa ukwelashwa kokuqhuma kwesibhamu, ukuhlangabezana ne-Swedish Rust Ukususwa okujwayelekile Sa2.5, futhi ngokushesha ufafazwe nge zinc ocebile workshop primer.
2. Amaphrofayili we-hull yangaphakathi aqhunyiswa isihlabathi ukuze ahlangabezane nezinga le-Swedish lokususa ukugqwala i-Sa2.5, futhi ngokushesha afuthwe nge-workshop ecebile zinc.
3. Ngemuva kokwelashwa okungaphezulu, i-primer ye-workshop kufanele ifuthwe ngokushesha ngangokunokwenzeka, futhi ayivunyelwe ukupenda ngemva kokubuyisela ukugqwala endaweni yensimbi.
Ukwelashwa kwesibili (ukwelashwa kwe-hull surface nge-primer noma ezinye izimbotshana ezibizwa ngokuthi ukwelashwa kwesibili) amazinga ayo ebanga kufanele ahambisane namazinga kazwelonke nawendawo.
6.3 Ukukhethwa kopende womkhumbi
1. Upende okhethiwe kufanele uhlangabezane nezimo zobuchwepheshe ezicacisiwe, upende olungafanelekile aluvunyelwe ukusetshenziselwa ukwakhiwa.
2. Ngaphambi kokuvula ikani, kufanele siqale sihlole ukuthi uhlobo lukapende, uhlobo, umbala kanye nesikhathi sokugcina kuyahambisana yini nezidingo zokusetshenziswa, nokuthi i-diluent iyahambisana yini.Uma ithini selivuliwe, kufanele lisetshenziswe ngokushesha.
3. Upende kufanele uxutshwe ngokugcwele ngemva kokuvula ikani, upende we-epoxy ukuze ungeze i-ejenti yokuphulukisa, ugovuze kahle, unake isikhathi sokuxuba, ngaphambi kokwakhiwa.4. Ngesikhathi sokwakha, uma upende udinga ukuhlanjululwa, i-diluent efanele kufanele yengezwe ngokuvumelana nemiyalelo yomkhiqizi wepende, futhi inani lokwengeza ngokuvamile alidluli i-5% yenani likapende.
6.4 Izidingo zendawo yokudweba
1.Umsebenzi wokupenda wangaphandle ngeke wenziwe ezindaweni ezinemvula, kuneqhwa, inkungu enzima kanye nezimo zezulu ezinomswakama.
2. Ungapendi endaweni emanzi.
3. Umswakama ongaphezu kuka-85%, izinga lokushisa langaphandle elingaphezu kuka-30℃, ngaphansi -5℃;Izinga lokushisa elingaphezulu kwepuleti lensimbi liyi-3 ℃ ngaphansi kwendawo yamazolo, futhi umsebenzi wokudweba awukwazi ukwenziwa.
4. Ungasebenzi endaweni enothuli noma engcolile.
6.5 Izidingo zenqubo yokwakha ukumboza
1. Indlela yokwakhiwa komdwebo we-hull izokwenziwa ngokuvumelana nalezi zidingo ezilandelayo:
a.Ipuleti elingaphandle le-hull, idekhi, ipuleti langaphandle ledekhi, ingaphakathi nangaphandle kwezindonga, kanye nezingxenye ezingaphezulu kwepuleti lembali le-OARS yephini lokugwedla egumbini lenjini zizofafazwa.
b.Ama-welds we-pre-paint manual, ama-fillet welds, i-back of profiles kanye nemiphetho yamahhala ngaphambi kokudweba.c.I-brush ne-roll coating izosetshenziswa kwezinye izingxenye.
2. Ukwakhiwa kuzokwenziwa ngokuhambisana ngokuqinile noHlu lwebanga lopende, inombolo yokugqoka kanye nefilimu eyomile Ukuqina kwengxenye ngayinye yesikebhe.
3. Upende kufanele uhlanzwe ngokuhambisana nezidingo zendawo yokumboza, uhlolwe ngabasebenzi abakhethekile futhi ugunyazwe omele umnikazi womkhumbi.
4. Uhlobo lwethuluzi lokupenda kufanele lufanele upende okhethiwe.Uma usebenzisa ezinye izinhlobo zikapende, isethi yonke yamathuluzi kufanele ihlanzwe kahle.
5. Uma upenda upende wokugcina, indawo yangaphambilini kufanele igcinwe ihlanzekile futhi yomile, futhi isikhathi sokumisa ngokuvamile singabi ngaphansi kwesikhashana esincane sokuphumula esishiwo umenzi.
6. Ukuze kuncishiswe umsebenzi wokuhlanza indawo yesibili, lapho i-weld, ukusika, uhlangothi lwamahhala (uhlangothi lwamahhala ludinga i-chamfering) kanye nezingxenye ezivuthayo zomlilo (hhayi ukufaka i-weld yokuhlola amanzi), kufanele kuhlanzwe ngokushesha ngemuva kwe-welding kanye nokusika ukucutshungulwa, ngopende we-primer workshop ehambisanayo.
