4. Uyilo kunye neenjongo zeNkqubo yokulwa nokugqwala

5. Inkqubo eneenkcukacha zokuLwa nokuGqobhoka

5.1 Inkqubo Yokulwa Nokugqwala Ehlala Ixesha Elide Ye-Body Chassis (Intsimbi Yetshaneli)
Itshasi, esebenza njengesiseko solwakhiwo oluthwala umthwalo weyunithi kwaye isoloko ikufutshane nomhlaba, isengozini yokukhukuliseka ngenxa yokuqokelelwa kwamanzi, ukufuma, ityuwa, njl. Ke ngoko, kusetyenziswa inkqubo yokulwa nokugqwala "enzima".

1. Unyango lwangaphambi koMphezulu - Ukuqhumisa okurhabaxa (Sa 2.5 Grade)
   • Injongo: Susa ngokupheleleyo isikali semill, umhlwa, i-weld spatter, amabala eoyile, kunye nazo zonke ezinye izinto ezingcolisayo kumphezulu wentsimbi, udale isiseko sesinyithi esicocekileyo nesomileyo kwaye wongeze uburhabaxa bomphezulu ukuze uphucule kakhulu ukunamathela kwengubo.
   • Umgangatho: Ukusebenzisa i-steel shot okanye i-grit njenge-abrasive, fikelela kwinqanaba lokucoca le-Sa 2.5 (Very Thorough Blast Cleaning), nto leyo ekhokelela kwimbonakalo yesinyithi efanayo kunye neprofayili yomphezulu (uburhabaxa) elawulwa phakathi kwe-40-75µm.
2. Umaleko oKhuselayo weMetallic - Ukutshiza ngeZinc
   • Injongo: Faka umaleko we-zinc coating ephezulu-purity kumphezulu wentsimbi ecociweyo nge-thermal spray. Umaleko we-zinc usebenza njenge-anode ye-sacrifice, ubonelela ngokhuseleko lwe-cathodic kwintsimbi. Nokuba i-coating yonakele kancinci, i-zinc iya kubola ngokukhethekileyo, ikhusele intsimbi engaphantsi.
   • Iiparameter zeNkqubo: Ubukhulu bomaleko weZinc bungadluli kwi-80µm. Inkqubo yokutshiza kufuneka ifane, ingaphoswa.
3. Umaleko oKhuselayo woMqobo - Ipeyinti yeBituminous enzima
   • Injongo: Faka ipeyinti yebhituminous esebenza kakhulu phezu komaleko otshizwe yizinc. Ipeyinti yebhituminous inika ukumelana okuhle namanzi, ukufuma, ukugqwala komhlaba, kunye nokuzinza kweekhemikhali, okwenza umqobo oqinileyo noqinileyo ohlukanisa ngokufanelekileyo ukufuma kunye neoksijini.
   • Imfuneko yesicelo: Sebenzisa isitshizi esingenamoya ophezulu ukuqinisekisa ukuba zonke iikona kunye nee-welds zigqunywe ngokulinganayo. Faka ubuncinane ii-coats ezimbini, ukufezekisa ubukhulu be-Dry Film (DFT) obungaphantsi kwe-200µm. Ifilimu ecociweyo kufuneka igudileyo xa uyichukumisa, ingabi naziphene, ingabi naziphene, ingabi naziphene, ingabi naziphene, ingabi naziphene, okanye ezinye iziphene.

5.2 Inkqubo Yokulwa Nokugqwala KweePaneli Zomzimba Neendawo Zangaphandle
Iiphaneli zomzimba zifuna zombini ukhuseleko lokugqwala kunye nobuhle, yiyo loo nto kusetyenziswa inkqubo edibeneyo ye-primer + topcoat.

1. Unyango lwangaphambi komphezulu - Unyango lwangaphambi kweKhemikhali
   • Ukuhamba kweNkqubo: Ukususa amafutha (susa iioyile) → Ukuhlamba → I-Phosphating (yenza i-phosphate conversion coating ephucula ukumelana nokugqwala kunye nokunamathela kwepeyinti) → Ukuhlamba → Ukomisa.
   • Umgangatho: Umaleko wekristale yephosphate kufuneka ube mhle, uqhubeke, kwaye ufane.
2. I-Primer Coating - I-Primer etyebileyo kwi-Epoxy Zinc
   • Injongo: Ibonelela ngokusebenza kakuhle kakhulu ekulweni nomhlwa kunye nomsebenzi wokukhusela i-cathodic (umgaqo ofanayo nokutshiza i-zinc). Inkqubo ye-epoxy resin inika ukumelana okuhle kakhulu kweekhemikhali kunye nokunamathela.
   • Imfuneko yesicelo: Futha ii-coats ezi-1-2, ufikelele kwi-Dry Film Thickness (DFT) ubuncinane i-50µm.
3. I-Topcoat Coat - I-UV enganyangekiyo / I-Anti-aging Topcoat
   • Injongo: Njengomaleko ongaphandle, iyakwazi ukumelana ngokuthe ngqo neemeko zokusingqongileyo ezifana nokukhanya kwelanga, imvula, kunye nokutshintsha kwamaqondo obushushu. Sisebenzisa i-polyurethane topcoat esebenza kakhulu.
   • Iimpawu:
     • Ukumelana okuhle kakhulu kwe-UV: Iqulethe izifunxi ze-UV kunye neziqinisi, ezicothisa ukufiphala kombala kunye nokulahleka kwe-gloss okubangelwa kukukhanya kwelanga.
     • Ukuthintela ukwaluphala: Ifilimu yepeyinti inokuguquguquka okuhle, inokumelana nokukhula nokuncipha kobushushu, kwaye ayiqhekezi okanye itshixeke.
     • Umbala ophezulu kunye nokugcinwa kweGloss: Ukwenziwa okuphucukileyo kuqinisekisa ukuba akukho kufiphala okukhulu, ukulahleka kokukhazimla, okanye itshokhwe kwiminyaka eli-10.
   • Imfuneko yesicelo: Futha ii-coats ezimbini, ufikelele kwi-Dry Film Thickness (DFT) engaphantsi kwe-50µm. Umbala kufuneka ufane kwaye ufane, ube nembonakalo egudileyo, ethe tyaba engenamaxolo eorenji, ukugoba, ukubaleka, okanye amasuntswana.

6. Uhlolo loMgangatho kunye noLawulo

• Uhlolo oluqhutywa kwinkqubo: Ukuhlolwa nokurekhoda inyathelo ngalinye lenkqubo nge-100% (ukucoceka kunye neprofayili yokuqhumisa, ubukhulu bomaleko we-zinc, ubukhulu befilimu yepeyinti nganye).
• Uhlolo lokugqibela:
  • Inkangeleko: Ifilimu yepeyinti kufuneka igudileyo, ifane ngombala, ingabi nazimfanta, ixobuke, irhoxe, ibalekele, ingabi namabhamuza, imikrwelo, okanye naziphi na ezinye iziphene. Ithambile xa uyichukumisa.
  • Ukujonga Ubukhulu beFilimu: Sebenzisa iigeyiji zobukhulu bombane obusebenzisa imagnethi okanye i-eddy ukuze ulinganise ubukhulu befilimu eyomileyo kwiindawo ezininzi, ukuqinisekisa ukuba iyahambelana neemfuno zoyilo.
  • Uvavanyo lokunamathela: Yenza uvavanyo lwesampulu olunqamlezileyo, ufikelele kwinqanaba le-0 okanye eli-1 (akukho kususwa kwepeyinti).

7. Isiphelo
Iiseti zejenereyitha yedizili ezikwizikhongozeli esizibonelelayo, ngeenkqubo ezicwangcisiweyo nezisemgangathweni zokulwa nokugqwala ezichazwe apha ngasentla, ziquka inkqubo yokukhusela enemigangatho emininzi edibanisa "ukhuseleko lwe-cathodic" kunye "nokhuseleko lokuthintela ngokwasemzimbeni." Le nkqubo imelana ngempumelelo nokugqwala kwiindawo ezahlukeneyo ezinzima, ihlangabezana ngokupheleleyo kwaye igqitha iimfuno zobugcisa ezingqongqo "zeminyaka engama-30 ngaphandle kokugqwala kwitshasi kunye neminyaka eli-10 ngaphandle kokufiphala, ukuxinana, okanye ukutshixa i-topcoat yomzimba." Oku kuqinisekisa ukuthembeka okuphezulu kunye nokukhanga kobuhle kwiseti yejenereyitha kuyo yonke ijikelezo layo lobomi.
