1. Zvido zvehunyanzvi zvekupenda ngarava
Chinhu chikuru chependi inorwisa ngura ndeye anti-ngura pigment bhokisi rekugadzira firimu, imhando yekuvhara yekudzivirira simbi kubva kumhepo, mvura, nezvimwewo, kana electrochemical corrosion.Antirust pendi yakakamurwa kuita muviri uye makemikari antirust pendi mapoka maviri.Mavara emuviri nependi zvinoumba firimu kudzivirira kupinda kwezvinhu zvinoparadza, zvakadai sesimbi tsvuku, graphite anticorrosive paint, etc. Kemikari nekemikari rust inhibition ye ngura pigments kudzivirira ngura, yakadai semutobvu mutsvuku, zinc yellow anticorrosive paint.Inowanzoshandiswa mumabhiriji akasiyana-siyana, ngarava, pombi dzemba uye dzimwe simbi dziviriro yekudzivirira.
2. Kuvaka mitemo yepende yengarava
Kupfapfaidza kwengarava kunowanzo shandiswa nekupfapfaidza kusingafeki kwemhepo, iyi nzira yekuvaka pendi yepamusoro-soro inoreva kushandiswa kwependi yekupfapfaidza pendi, pendi paburi remuromo inomanikidzwa kuatomize, kupfapfaidza pamusoro pejasi kuti igadzire pendi. film.Kuenzaniswa nekupfapfaidza nzira, kushandiswa kwependi yekupfapfaidza isina mhepo isingabhururuke, kukwirira kwepamusoro uye inogona kuve yakashongedzwa nefirimu rakakura, saka inonyanya kukodzera kune yakakura nzvimbo yekuvaka application.Asi kuchenjerera kunofanira kubhadharwa kudzivirira moto paunenge uchishandisa spraying isina airless.Naizvozvo, pneumatic high-pressure airless spray machine yave sarudzo yekutanga yekupfapfaidza Marine.Parizvino, dzinenge nzvimbo dzese dzengarava dzinoshandisa muchina uyu pakupenda nzvimbo dzakakura.
3. Inokurudzirwa kumwaya muchina wakakodzera Marine spraying
HVBAN yakaunza HB310/HB330/HB370 pneumatic spray machine series.Yakavakirwa kutenderedza kufamba uye kuita kwepamusoro, iyi inodhura-inoshanda mutsara wemashini ekupfapfaidza pneumatic ndiyo yakakwana kune yega yega Marine kupfapfaidza timu.
Aya akapupurirwa uye akasimba ekupfapfaidza akanakira vhoriyamu yakakwira uye yakakwira isingapinde mvura, inodzivirira moto uye inodzivirira pendi maapplication, ichipa kurerukirwa kukuru uye kukosha kune wese makondirakiti.
4. Ngarava yependi yekuvaka teknolojia
Ngarava yacho inofanira kupendwa nemateru akati wandei ependi inorwisa ngura, primer, pendi yepamusoro uye pendi yemvura yakachena.Vatengesi vependi yengarava vanowanzotumira vashandi kuti vape nhungamiro yehunyanzvi panzvimbo yekuvaka, uye zvinodiwa zvependi zvakasiyana munzvimbo dzakasiyana uye hunyoro hwakasiyana.
5. Zvinyorwa zvekupenda ngarava
Pendi yengarava imhando yepende inogona kuiswa pamusoro pechikepe.Chinangwa chikuru chepende yengarava ndechekuwedzera hupenyu hwebasa rechikepe uye kusangana nezvinodiwa zvakasiyana zvechikepe.Pendi yengarava inosanganisira pendi yepasi inodzivirira kupisa, pendi yemvura yekunwa, pendi yakaoma yetangi rekutakura uye mamwe pendi.Tevere isu tichanzwisisa maitiro eMarine pendi uye maitiro ekuputira.
6.1 Hunhu hwepende yengarava
Ukuru hwechikepe hunoratidza kuti pendi yengarava inofanira kukwanisa kuoma patembiricha yekamuri.Pendi inoda kupisa uye kuomeswa haina kukodzera Marine pendi.Nzvimbo yekuvaka yepende yeMarine yakakura, saka pende inofanira kunge yakakodzera kune yakakwirira-kudzvinyirira airless spraying operation.Kuvaka mune dzimwe nzvimbo dzechikepe kwakaoma, saka zvinotarisirwa kuti pendi inogona kusvika pakakwirira firimu ukobvu, saka gobvu firimu pendi inowanzodiwa.Nzvimbo dzepasi pemvura dzechikepe dzinowanzoda kuchengetedzwa kwecathodic, saka pendi inoshandiswa kune zvikamu zvepasi pemvura zvehull inoda kuve nekugona kugona kupikisa uye alkaline kuramba.Oiri - yakavakirwa kana mafuta - yakagadziriswa pendi iri nyore ku saponification uye haina kukodzera kugadzirwa kwepende pasi pemvura.Ngarava kubva pakuona kwekuchengetedzwa kwemoto, imba yeinjini yemukati, superstructure yemukati pendi haisi nyore kupisa, uye kamwe kutsva hakuzobudisi utsi hwakawandisa.Naizvozvo, nitro pendi uye chlorinated rabha pendi hazvina kukodzera ngarava kabhini yekushongedza pendi.
6.2 Zvinodiwa zvechikepe chependi coating process
1. Hull okunze panel, deck panel, bulkhead panel, bulwboard, superstructure okunze panel, yomukati uriri uye composite Profiles uye mamwe mapanera mukati, asati kuburutswa uchishandisa pfuti blasting kurapwa, kusangana Swedish ngura kubvisa mwero Sa2.5, uye pakarepo akapfapfaidza pamwe zinc rakapfuma workshop primer.
2. Maprofiles emukati mehull akaputirwa nejecha kuti asangane neSwedish ngura yekubvisa chiyero Sa2.5, uye pakarepo akapfapfaidza zinc-rich workshop primer.
3. Mushure mekurapa kwepamusoro, primer workshop inofanira kupfapfaidzwa nokukurumidza sezvinobvira, uye haibvumirwi kupendwa mushure mokudzorera ngura pamusoro pesimbi.
Kurapwa kwechipiri (hull surface treatment ine primer kana mamwe machira anonzi kurapa kwechipiri) magiredhi ayo anoenderana nemitemo yenyika uye yemuno.
6.3 Kusarudzwa kwepende yengarava
1. Pendi yakasarudzwa inofanira kusangana neyakatsanangurwa mamiriro ehunyanzvi, pendi isina kukodzera haibvumidzwe kushandiswa pakuvaka.
2. Tisati tavhura gaba, tinofanira kutanga tatarisa kana pendi yakasiyana-siyana, mhando, ruvara uye nguva yekuchengetedza inopindirana nezvinodiwa zvekushandisa, uye kana diluent inopindirana.Kana gaba ravhurwa, rinofanira kushandiswa nekukasika.
3. Paint inofanira kusanganiswa zvakakwana mushure mekuvhura gaba, epoxy pendi kuti uwedzere kuporesa mumiririri, kunyatsokurudzira, teerera kune nguva yekusanganiswa, isati yavakwa.4. Panguva yekuvaka, kana pendi ichida kuderedzwa, diluent yakakodzera inofanira kuwedzerwa maererano nemirairo yemugadziri wepende, uye huwandu hwekuwedzera kazhinji haupfuuri 5% yehuwandu hwepende.
6.4 Zvinodiwa zvenzvimbo yekupenda
1.Kushanda kwekupenda kwekunze hakuzoitirwe mukunaya, kune chando, mhute inorema uye mamiriro ekunze ane hunyoro.
2. Usapende panzvimbo yakanyorova.
3. Humidity pamusoro 85%, kunze tembiricha pamusoro 30 ℃, pazasi -5 ℃;Kupisa kwepamusoro kwesimbi ndiro 3 ℃ pazasi pedova, uye basa rekupenda harigone kuitwa.
4. Usashande munzvimbo ine huruva kana yakasvibiswa.
6.5 Maitiro anodiwa pakuvaka kukoira
1. Nzira yekuvaka yekupenda hull ichaitwa maererano nezvinodiwa zvinotevera:
a.Indiro yekunze yehull, dhizaini, plate yekunze yedeki, mukati nekunze kwemadziro, uye zvikamu zviri pamusoro peruvara rweruva rweOARS muimba yeinjini zvichapfapfaidzwa.
b.Pre-paint manual welds, fillet welds, kumashure kweprofiles uye mipendero yemahara isati yapenda.c.Brush uye roll coating ichaiswa kune zvimwe zvikamu.
2. Kuvaka kuchaitwa zvakanyatsoenderana neRondedzero yependi giredhi, coating nhamba uye yakaoma firimu Ukobvu chimwe nechimwe chikamu hove.
3. Paint inofanira kucheneswa maererano nezvinodiwa zvekuputira pamusoro, kuongororwa nevashandi vane ruzivo uye kubvumirwa nemumiririri wemuridzi wechikepe.
4. Rudzi rwechishandiso chepende chinofanira kunge chakakodzera pende yakasarudzwa.Paunenge uchishandisa mamwe marudzi epende, seti yese yezvishandiso inofanira kunyatsocheneswa.
5. Paunenge uchipenda pendi yekupedzisira, nzvimbo yapfuura inofanira kuchengetwa yakachena uye yakaoma, uye nguva yekuomeswa kazhinji haisi pasi penguva shoma yekuputira nguva inotarwa nemugadziri.
6. Kuti uderedze basa rekutsvaira kwechipiri chepamusoro, apo weld, kucheka, rutivi rwekusununguka (ruvara rwekusununguka runoda chamfering) uye zvikamu zvinopisa moto (zvisingasanganisire mvura yekuedza weld), inofanira kucheneswa pakarepo mushure mekucheka nekucheka kushandiswa, pamwe nependi yeworkshop inoenderana.
