1. Isifinyezo Sombiko
Lo mbiko uchaza kabanzi ngezinqubo zokwelapha ezibanzi nezihlala isikhathi eside zokulwa nokugqwala ezisetshenziswa kithiamasethi ejeneretha kadizili afakwe ezitsheniUhlelo lwethu lokulwa nokugqwala luklanywe ngokuqinile ngokwezindinganiso eziphakeme, lusebenzisa izixazululo ezihlukene nezesayensi ezenzelwe indawo yokusebenza kanye nezidingo zokulwa nokugqwala kwezingxenye ezahlukene zeyunithi, ikakhulukazi i-chassis yokuvikela kanye namaphaneli angaphandle. Inhloso eyinhloko ukuqinisekisa ukuthi isakhiwo se-chassis sihlala singenakho ukugqwala iminyaka engama-30, futhi i-topcoat yephaneli yomzimba imelana nokugqwala, ukugqwala, kanye nokushiswa iminyaka eyi-10, kufinyelela amazinga ahamba phambili embonini kokubili ekubukekeni nasekuqineni kweyunithi iyonke.
2. Ububanzi Bokusetshenziswa
Le nqubo yokulwa nokugqwala isebenza ezindaweni zangaphandle, izingxenye zesakhiwo sangaphakathi, futhi ikakhulukazi i-chassis yokuvikela ye-canopy kanye nomzimba wawo wonke amasethi ejeneretha kadizili afakwe ezitsheni akhiqizwe yi-[Supplier Company Name].
3. Izindinganiso Ezibhekiselwe Kuzo
- I-GB/T 30790 "Ukuvikelwa kwezakhiwo zensimbi ngezinhlelo zokupenda ezivikelayo"
- I-ISO 12944 "Upende nama-varnish - Ukuvikelwa kokugqwala kwezakhiwo zensimbi yizinhlelo zopende ezivikelayo"
- I-GB/T 9271 "Upende nama-varnish - Amaphaneli ajwayelekile okuhlola"

4. Umklamo kanye Nezinhloso Zesistimu Yokulwa Nokugqwala
| Ingxenye | Inhloso Yokulwa Nokugqwala | Inqubo Yokwelapha Eyinhloko |
| I-Chassis Yokuvikela I-Canopy Yeyunithi (Insimbi Yesiteshi) | Kuqinisekisiwe iminyaka engama-30 ngaphandle kokugqwala | Ukuqhuma Okubi → Ukufutha Nge-Zinc → Upende We-Bituminous Onzima |
| Izindawo Zomzimba Zangaphandle (Amaphaneli) | Kuqinisekisiwe iminyaka eyi-10 ngaphandle kokuphela, ukushiswa, noma ukushiswa ngoshoki | Ukwelashwa Kwangaphambi Kokwelashwa (Ukususa Amafutha, Ukuphosphating) → I-Primer Ecebile Nge-Epoxy Zinc → I-Topcoat Emelana Ne-UV |
5. Ukugeleza Kwenqubo Yokulwa Nokugqwala Okuningiliziwe
5.1 Inqubo Ehlala Isikhathi Eside Yokulwa Nokugqwala Kwe-Body Chassis (Insimbi Yesiteshi)
I-chassis, esebenza njengesakhiwo esiyisisekelo seyunithi esithwala umthwalo futhi ehlala iseduze nomhlabathi, isengozini yokuguguleka ngenxa yokuqongelela kwamanzi, umswakama, usawoti, njll. Ngakho-ke, kusetshenziswa uhlelo lokulwa nokugqwala olusezingeni eliphezulu kakhulu.
- Ukwelashwa Kwangaphambi Komphezulu - Ukuqhumisa Okubi (Ibanga lika-Sa 2.5)
- Inhloso: Susa ngokuphelele isikali semishini, ukugqwala, i-weld spatter, amabala kawoyela, nazo zonke ezinye izinto ezingcolisayo ebusweni bensimbi, udale isisekelo sensimbi esihlanzekile, esomile futhi wandise ubulukhuni bomphezulu ukuze uthuthukise kakhulu ukunamathela kwe-coating.
- Okujwayelekile: Usebenzisa i-steel shot noma i-grit njenge-abrasive, finyelela izinga lokuhlanza le-Sa 2.5 (Very Thorough Blast Cleaning), okuholela ekubukekeni kwensimbi okufanayo kanye nephrofayili yomphezulu (ubulukhuni) okulawulwa phakathi kuka-40-75µm.
- Isendlalelo Esivikelayo Sensimbi - Ukufutha Nge-Zinc
- Inhloso: Faka ungqimba lwe-zinc coating oluhlanzekile kakhulu phezu kwensimbi ehlanziwe nge-thermal spray. Ungqimba lwe-zinc lusebenza njenge-anode yomhlatshelo, luhlinzeka ngokuvikelwa kwe-cathodic ensimbini. Ngisho noma i-coating yonakele kancane, i-zinc izobola ngokukhethekile, ivikele insimbi engaphansi.
- Amapharamitha Enqubo: Ubukhulu besendlalelo se-zinc obungaphansi kuka-80µm. Inqubo yokufafaza kumele ifane, ngaphandle kokuphazamiseka.
- Isendlalelo Esivikelayo Sesithiyo - Upende We-Bituminous Onzima
- Inhloso: Faka upende we-bituminous osebenza kahle kakhulu phezu kwesendlalelo esifuthwe nge-zinc. Upende we-bituminous unikeza ukumelana okuhle kakhulu namanzi, umswakama, ukugqwala kwenhlabathi, kanye nokuqina kwamakhemikhali, okwenza isithiyo esiqinile nesiqinile esihlukanisa ngempumelelo umswakama nomoya-mpilo.
- Isidingo Sesicelo: Sebenzisa isifutho esingenamoya ophakeme ukuqinisekisa ukumbozwa okufanayo kwawo wonke amakhona kanye nama-weld. Faka okungenani amajazi amabili, ufinyelele ubukhulu befilimu eyomile (DFT) obungaphansi kwama-200µm. Ifilimu epholile kufanele ibe bushelelezi uma uyithinta, ingabi nokugoba, ukugeleza, amabhamuza, noma ezinye izinkinga.
5.2 Inqubo Yokulwa Nokugqwala Kwamaphaneli Omzimba Nezindawo Zangaphandle
Amaphaneli omzimba adinga kokubili ukuvikelwa kokugqwala kanye nobuhle, ngakho-ke kusetshenziswa uhlelo oluhlanganisiwe lwe-primer + topcoat.
- Ukwelashwa Kwangaphambi Komphezulu - Ukwelashwa Kwangaphambi Kokhemikhali
- Ukugeleza Kwenqubo: Ukususa amafutha (ukususa amafutha) → Ukuhlanza → I-Phosphating (yakha ungqimba lokuguqulwa kwe-phosphate oluthuthukisa ukumelana nokugqwala kanye nokunamathela kopende) → Ukuhlanza → Ukomisa.
- Okujwayelekile: Ingqimba yekristalu ye-phosphate kufanele ibe yinhle, iqhubeke, futhi ifane.
- I-Primer Coating - I-Primer ecebile nge-Epoxy Zinc
- Inhloso: Inikeza ukusebenza okuhle kakhulu kokulwa nokugqwala kanye nomsebenzi wokuvikela i-cathodic (isimiso esifana nokufutha nge-zinc). Uhlelo lwe-epoxy resin lunikeza ukumelana okuhle kakhulu kwamakhemikhali kanye nokunamathela.
- Isidingo Sesicelo: Futha amajazi angu-1-2, uthole ubukhulu befilimu eyomile (DFT) okungenani ama-50µm.
- Isimbozo Se-Topcoat - Isimbozo Se-UV Esimelana Nokuguga / Esilwa Nokuguga
- Inhloso: Njengesendlalelo sangaphandle, simelana ngqo nezici zemvelo ezifana nokukhanya kwelanga, imvula, kanye nokushintshashintsha kwezinga lokushisa. Sisebenzisa i-polyurethane topcoat esebenza kahle kakhulu.
- Izici:
- Ukumelana Okuhle Kakhulu Kwe-UV: Iqukethe izifutho ze-UV kanye neziqinisi, okubambezela ngempumelelo ukufiphala kombala kanye nokulahleka kokukhanya okubangelwa ukukhanya kwelanga.
- Ukulwa nokuguga: Ifilimu yopende inokuguquguquka okuhle, ingamelana nokukhula nokuncipha kokushisa, futhi ayivami ukuqhekeka noma ukushova.
- Ukugcinwa Kombala Ophezulu Nokukhanya Okukhazimulayo: Ukwakheka okuthuthukisiwe kuqinisekisa ukuthi akukho ukufiphala okukhulu, ukulahleka kokucwebezela, noma ukushoba phakathi neminyaka eyi-10.
- Isidingo Sesicelo: Futha amajazi amabili, ufinyelele ku-Dry Film Thickness (DFT) okungenani ama-50µm. Umbala kufanele ufane futhi uhambisane, ube nokubukeka okubushelelezi, okuyisicaba okungenamaxolo anombala o-orenji, ukugoba, ukugijima, noma izinhlayiya.
6. Ukuhlolwa Nokulawulwa Kwekhwalithi
- Ukuhlolwa Kwenqubo: Ukuhlolwa nokuqoshwa okungu-100% kwesinyathelo ngasinye senqubo (ukuhlanzeka kokuqhumisa kanye nephrofayili, ukujiya kwengqimba ye-zinc, ukujiya kwefilimu yopende ngayinye).
- Ukuhlolwa Kokugcina:
- Ukubukeka: Ifilimu yopende kufanele ibe bushelelezi, ifane ngombala, ingabi nemifantu, ukuxebuka, ukugoba, ukugeleza, amabhamuza, imihuzuko, noma ezinye izinkinga. Bushelele uma uthinta.
- Ukuhlola Ubukhulu Befilimu: Sebenzisa amageyiji obukhulu bamanje anamandla noma aqinile ukuze ulinganise ubukhulu befilimu eyomile ezindaweni eziningi, uqinisekise ukuthi uyahambisana nezidingo zomklamo.
- Ukuhlolwa Kokunamathela: Yenza ukuhlolwa kokuthatha amasampula, uthole isilinganiso esingu-0 noma esingu-1 (akukho ukususwa kopende).
7. Isiphetho
Amasethi ejenereyitha kadizili afakwe ezitsheni esiwahlinzekayo, ngezinqubo ezihlelekile nezijwayelekile zokulwa nokugqwala ezichazwe ngenhla, afaka uhlelo lokuvikela olunezingqimba eziningi oluhlanganisa "ukuvikelwa kwe-cathodic" kanye "nokuvikelwa kwezithiyo zomzimba." Lolu hlelo lumelana ngempumelelo nokugqwala ezindaweni ezahlukahlukene ezinzima, luhlangabezana ngokugcwele futhi ludlula izidingo zobuchwepheshe eziqinile "zeminyaka engama-30 ngaphandle kokugqwala kweshasi kanye neminyaka eyi-10 ngaphandle kokufiphala, ukugqwala, noma ukushova kwejazi lomzimba." Lokhu kuqinisekisa ukuthembeka okuphezulu kanye nokukhanga kobuhle kwesethi yejeneretha kuyo yonke impilo yayo.
