1. Zofunikira zaukadaulo pakupenta zombo
Chigawo chachikulu cha utoto wotsutsa dzimbiri ndi anti-dzimbiri pigment bokosi kupanga chinthu, ndi mtundu wa zokutira kuteteza zitsulo pamwamba mpweya, madzi, etc., kapena electrochemical dzimbiri.Utoto wa Antirust umagawidwa kukhala utoto wakuthupi ndi mankhwala odana ndi zotupa m'magulu awiri.Thupi inki ndi utoto kupanga filimu kuteteza kuukira kwa dzimbiri zinthu, monga chitsulo wofiira, graphite anticorrosive utoto, etc. Mankhwala ndi mankhwala dzimbiri chopinga wa dzimbiri inki kuteteza dzimbiri, monga wofiira lead, nthaka yellow anticorrosive utoto.Nthawi zambiri ntchito milatho zosiyanasiyana, zombo, m'nyumba mapaipi ndi zina zitsulo dzimbiri kupewa.
2. Miyezo yomanga ya utoto wa zombo
Kupopera mbewu kwa zombo nthawi zambiri kumagwiritsidwa ntchito ndi kupopera mbewu mankhwalawa mopanda mpweya wambiri, njira yopangira utoto wapamwamba kwambiri imatanthawuza kugwiritsa ntchito utoto wopopera wopopera kwambiri, utoto pamtundu wa nozzle umakakamizika kuti atomize, utsi pamwamba pa zokutira kuti apange utoto. kanema.Poyerekeza ndi kupopera mbewu mankhwalawa, kugwiritsa ntchito mpweya kupopera utoto pang`ono zouluka, dzuwa mkulu ndipo akhoza TACHIMATA ndi thicker filimu, choncho makamaka oyenera ntchito yaikulu yomanga dera.Koma chidwi chiyenera kuperekedwa pakupewa moto mukamagwiritsa ntchito kupopera popanda mpweya.Chifukwa chake, makina opopera opopera opanda mpweya opumira kwambiri akhala chisankho choyamba kupopera mbewu za Marine.Pakali pano, pafupifupi malo onse osungiramo zombo amagwiritsa ntchito makinawa pojambula malo akuluakulu.
3. Makina opoperapo ovomerezeka oyenera kupopera mbewu mankhwalawa Marine
HVBAN anayambitsa HB310/HB330/HB370 pneumatic kutsitsi mndandanda.Womangidwa mozungulira kuyenda komanso magwiridwe antchito apamwamba, mzere wotsika mtengo wa makina opopera a pneumatic ndiwothandizira bwino gulu lililonse lopopera mbewu za Marine.
Zopopera zotsimikiziridwa komanso zolimbazi ndizoyenera kutulutsa mphamvu zambiri komanso kuthamanga kwambiri kosalowa madzi, kukana moto komanso kuyika utoto woteteza, zomwe zimapereka mwayi komanso phindu lalikulu kwa womanga aliyense.
4. Ukadaulo womanga utoto wa sitima
Sitimayo iyenera kujambulidwa ndi zigawo zingapo za utoto wotsutsa dzimbiri, primer, utoto wapamwamba ndi utoto wowoneka bwino wamadzi.Opereka utoto pazombo nthawi zambiri amatumiza antchito kuti akapereke chitsogozo chaukadaulo pamalo omanga, ndipo zofunikira za utoto zimasiyana m'malo osiyanasiyana komanso chinyezi chosiyana.
5. Zofotokozera za kujambula kwa sitima
Utoto wa ngalawa ndi mtundu wa utoto womwe ungagwiritsidwe ntchito pamwamba pa sitimayo.Cholinga chachikulu cha utoto wa ngalawa ndikutalikitsa moyo wautumiki wa sitimayo ndikukwaniritsa zosowa zosiyanasiyana za sitimayo.Utoto wa sitimayo umaphatikizapo utoto wothira pansi pa sitima yapamadzi, utoto wa tanki yamadzi akumwa, utoto wouma wa tanki yonyamula katundu ndi utoto wina.Kenako timvetsetsa mawonekedwe a utoto wa Marine ndi njira zokutira.
6.1 Makhalidwe a utoto wa zombo
Kukula kwa sitimayo kumatsimikizira kuti utoto wa sitimayo uyenera kuuma kutentha.Utoto womwe umayenera kutenthedwa ndikuwumitsidwa siwoyenera utoto wa Marine.Malo opangira utoto wa Marine ndi wamkulu, kotero utotowo uyenera kukhala woyenera pa ntchito yopopera mankhwala yopanda mpweya.Kumanga m'madera ena a sitimayo n'kovuta, kotero tikuyembekeza kuti chojambula chikhoza kufika pamtunda wapamwamba wa filimu, kotero kuti utoto wochuluka wa filimu umafunika nthawi zambiri.Mbali za pansi pamadzi za sitimayo nthawi zambiri zimafunikira chitetezo cha cathodic, choncho utoto womwe umagwiritsidwa ntchito m'madzi a pansi pamadzi amadzimadzi umayenera kukhala ndi mphamvu yotsutsa komanso kukana kwa alkaline.Mafuta - opangidwa kapena mafuta - utoto wosinthidwa ndi wosavuta ku saponification ndipo siwoyenera kupanga utoto pansi pa madzi.Zombo kuchokera pakuwona chitetezo chamoto, chipinda cha injini mkati, utoto wamkati wa superstructure sizovuta kuwotcha, ndipo kamodzi kuyaka sikudzatulutsa utsi wambiri.Chifukwa chake, utoto wa nitro ndi utoto wa rabara wothira chlorini sizoyenera kupenta kukongoletsa kanyumba ka sitima.
6.2 Zofunikira pakupaka utoto wa sitima yapamadzi
1. Hull gulu akunja, gulu sitimayo, gulu bulkhead, bulwboard, superstructure gulu lakunja, pansi pansi ndi gulu mbiri ndi mapanelo ena mkati, pamaso kutsitsa ntchito kuwombera kuphulika mankhwala, kukumana ndi Swedish dzimbiri kuchotsa muyezo Sa2.5, ndipo nthawi yomweyo sprayed ndi zinc olemera workshop primer.
2. Zojambula zamkati zamkati zimapukutidwa ndi mchenga kuti zigwirizane ndi muyezo waku Sweden wochotsa dzimbiri wa Sa2.5, ndipo nthawi yomweyo amawaza ndi zinc-rich workshop primer.
3. Pambuyo pa chithandizo chapamwamba, choyambira cha msonkhano chiyenera kupopera mwamsanga, ndipo sichiloledwa kupaka utoto pambuyo pobwezeretsa dzimbiri pazitsulo.
Chithandizo chachiwiri (kuchiza kwa hull surface ndi primer kapena zokutira zina zomwe zimatchedwa chithandizo chachiwiri) miyezo yake yamagulu iyenera kugwirizana ndi miyezo ya dziko ndi dera.
6.3 Kusankha utoto wa zombo
1. Utoto wosankhidwa uyenera kukwaniritsa zofunikira zaukadaulo, utoto wosayenerera suloledwa kugwiritsidwa ntchito pomanga.
2. Tisanatsegule chidebe, choyamba tiyenera kuyang'ana ngati mitundu ya utoto, mtundu, mtundu ndi nthawi yosungira ikugwirizana ndi zofunikira zogwiritsira ntchito, komanso ngati diluent ikugwirizana.Chitini chikatsegulidwa, chiyenera kugwiritsidwa ntchito nthawi yomweyo.
3. Utoto uyenera kusakanikirana bwino mutatha kutsegula chitini, utoto wa epoxy kuti uwonjezere kuchiritsa, kusonkhezera bwino, tcherani khutu ku nthawi yosakaniza, musanamangidwe.4. Pakumanga, ngati utoto uyenera kuchepetsedwa, diluent yoyenera iyenera kuwonjezeredwa molingana ndi malangizo a wopanga utoto, ndipo kuchuluka kwake sikudutsa 5% ya kuchuluka kwa utoto.
6.4 Zofunikira pakupenta malo
1.Kujambula panja sikudzachitidwa mumvula, chipale chofewa, chifunga cholemera komanso nyengo yamvula.
2. Osapaka utoto pamtunda wonyowa.
3. Chinyezi pamwamba 85%, panja kutentha pamwamba 30 ℃, m'munsimu -5 ℃;Kutentha kwapamtunda kwa mbale yachitsulo ndi 3 ℃ pansi pa mame, ndipo ntchito yojambula singakhoze kuchitidwa.
4. Osagwira ntchito pamalo afumbi kapena oipitsidwa.
6.5 Zofunikira pakupanga zokutira
1. Njira yopangira zojambula za hull iyenera kuchitidwa molingana ndi izi:
a.Mbali yakunja ya hull, sitimayo, mbale yakunja ya sitimayo, mkati ndi kunja kwa mipanda, ndi mbali zomwe zili pamwamba pa mbale yamaluwa ya OARS mu chipinda cha injini ziyenera kupopera.
b.Ma welds opangira utoto, ma welds a fillet, kumbuyo kwa mbiri ndi m'mphepete mwaulere musanayambe kujambula.c.Burashi ndi mpukutu wokutira ayenera ntchito mbali zina.
2. Ntchito yomanga idzachitidwa motsatira Mndandanda wa kalasi ya utoto, ❖ kuyanika nambala ndi filimu youma Makulidwe a mbali iliyonse ya chombocho.
3. Utoto uyenera kutsukidwa mogwirizana ndi zofunikira za chophimba pamwamba, kuyang'aniridwa ndi antchito apadera ndikuvomerezedwa ndi woimira mwini zombo.
4. Mtundu wa chida cha utoto uyenera kukhala woyenera utoto wosankhidwa.Mukamagwiritsa ntchito utoto wamitundu ina, zida zonse ziyenera kutsukidwa bwino.
5. Pojambula utoto wotsiriza, malo apitawo ayenera kukhala oyera ndi owuma, ndipo nthawi yowumitsa nthawi zambiri imakhala yochepa kusiyana ndi nthawi yocheperapo yophimba yomwe imatchulidwa ndi wopanga.
6. Pofuna kuchepetsa ntchito ya yachiwiri pamwamba kuyeretsa, kumene kuwotcherera, kudula, ufulu mbali (mbali ufulu amafuna chamfering) ndi mbali moto moto (osati madzi kuyesa kuwotcherera), ayenera yomweyo kutsukidwa pambuyo kuwotcherera ndi kudula processing, ndi penti yofananira yoyambira.
