1. Iimfuno zobugcisa zokudweba iinqanawa
Inxalenye ephambili yepeyinti ye-anti-rust yi-anti-rust pigment box film forming substance, luhlobo lwengubo yokukhusela umphezulu wesinyithi ukusuka emoyeni, emanzini, njl., okanye i-electrochemical corrosion. Ipeyinti ye-Antirust yahlulwe ngokwepeyinti ye-antirust ebonakalayo kunye nemichiza ngamacandelo amabini. Imibala ebonakalayo kunye neepeyinti zenza ifilimu ukuthintela ukuhlasela kwezinto ezidlayo, ezifana nentsimbi ebomvu, ipeyinti yegraphite enqanda ukubola, njl. Ngokuqhelekileyo isetyenziswa kwiiBridges ezahlukeneyo, iinqanawa, imibhobho yendlu kunye nolunye uthintelo lwentsimbi yentsimbi.
2. Imigangatho yokwakha yepeyinti yenqanawa
Ukutshiza ngenqanawa ngokuqhelekileyo kusetyenziselwa ukutshiza ngokungenamoya koxinzelelo oluphezulu, le ndlela yolwakhiwo lwepeyinti yobugcisa obuphezulu ibhekisa kusetyenziso lwepeyinti yokutshiza yoxinzelelo oluphezulu, ipeyinti kwindawo yokuphuma yombhobho inyanzeleke ukuba i-atomize, isitshizi kumphezulu wepeyinti ukwenza ipeyinti. ifilimu. Xa kuthelekiswa nendlela yokutshiza, ukusetyenziswa kwepeyinti yokutshiza okungenamoya ukubhabha kancinci, ukusebenza kakuhle okuphezulu kwaye kunokufakwa ngefilimu eshinyeneyo, ngoko ke ifanelekile ngakumbi kwisicelo sokwakha indawo enkulu. Kodwa ingqalelo kufuneka ihlawulwe ekuthinteleni umlilo xa usebenzisa ukutshiza okungenamoya. Ke ngoko, umatshini wokutshiza ongenamoya woxinzelelo oluphezulu uye waba lukhetho lokuqala lokutshiza lwaseLwandle. Okwangoku, phantse zonke iindawo zeenqanawa zisebenzisa lo matshini xa zipeyinta iindawo ezinkulu.
3. Umatshini wokutshiza ocetyiswayo olungele ukutshiza eLwandle
I-HVBAN yazisa i-HB310/HB330/HB370 umatshini wokutshiza we-pneumatic. Eyakhelwe malunga nokuhamba kunye nokusebenza okuphezulu, lo mgca weendleko-osebenzayo womatshini wokutshiza we-pneumatic uhambelana ngokugqibeleleyo kwiqela ngalinye lokutshiza i-Marine.
Ezi zitshizi ziqinisekisiweyo kunye nezihlala zihlala zifanelekile kumthamo ophezulu kunye noxinzelelo oluphezulu lokungangeni kwamanzi, ukumelana nomlilo kunye nezicelo zepeyinti ezikhuselayo, ezinikezela ngokulula kunye nexabiso kwikontraki nganye.
4. Iteknoloji yokwakha ipeyinti yeenqanawa
Inqanawa iza kupeyintwa ngepeyinti eliqela yepeyinti echasene nomhlwa, iprimer, ipeyinti ephezulu kunye nepeyinti yamanzi ecacileyo. Ababoneleli bepeyinti yeenqanawa badla ngokuthumela abasebenzi ukuba banike isikhokelo sobugcisa kwindawo yokwakha, kwaye iimfuno zepeyinti zahlukile kwiindawo ezahlukeneyo kunye nokufuma okwahlukileyo.
5. Iinkcukacha zokupeyinta iinqanawa
Ipeyinti yenqanawa luhlobo lwepeyinti enokuthi ifakwe kumphezulu wenqanawa. Injongo ephambili yepeyinti yenqanawa kukwandisa ubomi benkonzo yenqanawa kunye nokuhlangabezana neemfuno ezahlukeneyo zenqanawa. Ipeyinti yenqanawa ibandakanya ipeyinti engaphantsi kwenqanawa, ipeyinti yetanki yamanzi okusela, ipeyinti eyomileyo yetanki yempahla kunye nezinye iipeyinti. Okulandelayo siza kuqonda iimpawu zepeyinti yaseLwandle kunye nenkqubo yokugqoka.
6.1 Iimpawu zepeyinti yenqanawa
Ubungakanani benqanawa bumisela ukuba ipeyinti yenqanawa kufuneka ikwazi ukoma kwiqondo lobushushu begumbi. Ipeyinti efuna ukufudunyezwa kwaye yomiswe ayifanelekanga ipeyinti yaseLwandle. Indawo yokwakhiwa kwepeyinti yaseMarine inkulu, ngoko ke ipeyinti ifanele ifaneleke kuxinzelelo oluphezulu lokutshiza olungenamoya. Ukwakhiwa kweminye imimandla yenqanawa kunzima, ngoko ke kuyathenjwa ukuba umzobo unokufikelela kubukhulu befilimu, ngoko ke ipeyinti eshinyeneyo isoloko ifuneka. Iindawo ezingaphantsi kwamanzi enqanaweni zihlala zifuna ukhuseleko lwe-cathodic, ngoko ke ipeyinti esetyenziselwa iindawo ezingaphantsi kwamanzi zenqanawa kufuneka ibe nokuxhathisa okufanelekileyo kunye nokuxhathisa kwealkaline. I-oyile-esekelwe okanye i-oyile-ipeyinti eguquliweyo ilula kwi-saponification kwaye ayifanelekanga ukuveliswa kwepeyinti ngaphantsi komgca wamanzi. Iinqanawa ukusuka kwindawo yokujonga ukhuseleko lomlilo, igumbi le-injini ngaphakathi, i-superstructure yepeyinti yangaphakathi ayilula ukutshisa, kwaye kanye ukutshisa akuyi kukhulula umsi ogqithiseleyo. Ke ngoko, ipeyinti ye-nitro kunye nepeyinti yerabha eneklorini ayifanelekanga kwipeyinti yokuhombisa ikhabhinethi yeenqanawa.
6.2 Iimfuno zenkqubo yokugquma ipeyinti yenqanawa
1. Iphaneli yangaphandle ye-Hull, ipaneli yomgangatho, ipaneli ye-bulkhead, i-bulwboard, ipaneli yangaphandle ye-superstructure, umgangatho wangaphakathi kunye neeprofayili ezidibeneyo kunye nezinye iipaneli zangaphakathi, ngaphambi kokukhulula usebenzisa unyango lokuqhunyiswa kwesibhamu, ukuhlangabezana ne-Swedish rust ukususwa umgangatho we-Sa2.5, kwaye ngokukhawuleza utshizwe kunye zinc rich workshop primer.
2. Iiprofayili ze-hull zangaphakathi zenziwe nge-sandblasted ukuhlangabezana nomgangatho wokususwa kwe-rust yaseSweden i-Sa2.5, kwaye ngokukhawuleza itshizwe nge-primer workshop ye-zinc-rich.
3. Emva kokunyanga kwendawo, i-primer ye-workshop kufuneka itshizwe ngokukhawuleza, kwaye ayivumelekanga ukuba ipeyinti emva kokubuyisela i-rust kwi-steel surface.
Unyango lwesibini (unyango lwe-hull surface kunye ne-primer okanye ezinye iingubo ezibizwa ngokuba zonyango lwesibini) imigangatho yomgangatho wayo iya kuhambelana nemigangatho yesizwe neyendawo.
6.3 Ukukhethwa kwepeyinti yenqanawa
1. Ipeyinti ekhethiweyo kufuneka ihlangabezane neemeko zobugcisa ezichaziweyo, ipeyinti engafanelekanga ayivumelekanga ukuba isetyenziselwe ukwakhiwa.
2. Ngaphambi kokuvula inkonkxa, kufuneka siqale sijonge ukuba uhlobo lwepeyinti, uphawu, umbala kunye nexesha lokugcinwa luyahambelana neemfuno zokusetyenziswa, nokuba i-diluent iyahambelana. Emva kokuba inkonkxa ivuliwe, kufuneka isetyenziswe ngokukhawuleza.
3. Ipeyinti kufuneka ixutywe ngokupheleleyo emva kokuvula i-can, ipeyinti ye-epoxy yokongeza i-ejenti yokunyanga, igxobhoze ngokucokisekileyo, ubeke ingqalelo kwixesha lokuxuba, ngaphambi kokwakhiwa. 4. Ngexesha lokwakha, ukuba ipeyinti ifuna ukuhlanjululwa, i-diluent efanelekileyo kufuneka yongezwe ngokwemiyalelo yomenzi wepeyinti, kwaye inani lokongezwa ngokubanzi alidluli i-5% yexabiso lepeyinti.
6.4 Iimfuno zendawo yokupeyinta
I-1.Umsebenzi wokupeyinta wangaphandle awuyi kwenziwa kwimvula, ikhephu, inkungu enzima kunye neemeko zemozulu ezifumileyo.
2. Musa ukupeyinta kwindawo emanzi.
3. Ukufuma okungaphezulu kwe85%, ubushushu bangaphandle bungaphezulu kwe-30℃, ngaphantsi kwe-5℃; Ubushushu bomphezulu weplate yensimbi yi-3 ℃ ngaphantsi kwendawo yombethe, kwaye umsebenzi wokupenda awukwazi ukwenziwa.
4. Musa ukusebenza kwindawo enothuli okanye engcolisekileyo.
6.5 Iimfuno zenkqubo yokwakhiwa kokugquma
1. Indlela yokwakhiwa komzobo we-hull iya kwenziwa ngokwezi mfuno zilandelayo:
a. Ipleyiti yangaphandle yeholi, umgangatho, ipleyiti yangaphandle yomgangatho, ngaphakathi nangaphandle kwinqaba, kunye namalungu angaphezulu kwepleyiti yeentyatyambo ye-OARS yegumbi le-injini ziyakutshizwa.
b. I-welds yangaphambili yokupeyinta, i-fillet welds, umva weeprofayili kunye nemiphetho yamahhala ngaphambi kokupeyinta. c. Ibrashi kunye neengubo zokugqoka ziya kufakwa kwezinye iindawo.
2. Ukwakhiwa kuya kuqhutywa ngokungqongqo ngokuhambelana noLuhlu lwebakala lepeyinti, inombolo yokwambathisa kunye nefilimu eyomileyo Ukutyeba kwenxalenye nganye ye-hull.
3. Ipeyinti kufuneka ihlanjululwe ngokuhambelana neemfuno zendawo yokugubungela, ihlolwe ngabasebenzi abakhethekileyo kwaye ivunywe ngummeli womnini mkhumbi.
4. Uhlobo lwesixhobo sokupenda kufuneka lufanelekele ipeyinti ekhethiweyo. Xa usebenzisa ezinye iintlobo zepeyinti, isethi yonke yezixhobo kufuneka icocwe kakuhle.
5. Xa upeyinta ipeyinti yokugqibela, indawo yangaphambili kufuneka igcinwe icocekile kwaye yomile, kwaye ixesha lokumisa ngokuqhelekileyo alikho ngaphantsi kwexesha elincinci lekhefu elichazwe ngumenzi.
6. Ukuze kuncitshiswe umsebenzi wokucoca umphezulu wesibini, apho i-weld, i-cut cut, i-free side (icala lamahhala lifuna i-chamfering) kunye neendawo zokutshisa umlilo (kungabandakanyi i-weld yokuvavanya amanzi), kufuneka ihlanjululwe ngokukhawuleza emva kwe-welding kunye ne-cutting processing, ngepeyinti yokuqala yeworkshop ehambelanayo.
