Kusho ukuthini i-2C2F ne-3C3F kuma-Panel kanye Nezicaciso Zokumboza
Ukubhalwa okufana no-2C2F noma 3C3F kuchaza uhlelo lwekhodi noma lwezinto ezigqunywe ngaphakathi ngokwezigaba nangokuphela kwazo esikhundleni samagama: isibalo sokuqala siyisibalo sezingxenye ohlelweni, u-C usho ingxenye, futhi izibalo ezilandelayo kanye no-F wesijobelelo zichaza izici zekhodi noma zefilimu kanye nokuphela. Ngokomsebenzi, lawa makhodi avela ezinhlelweni zokugqunywa nokupendwa kwamathangi okugcina, futhi into ebalulekile akukhona ukukhumbula ikhodi kodwa ukuqinisekisa ukuthi uhlelo luchaza uhlobo lwekhosti, ukujiya kwefilimu ngamamayikhromitha, izinga elihlolwa ngalo kanye nokulungiswa kwendawo. Amathangi ensimbi agqunywe ngengilazi awadingi uhlelo lokupenda nhlobo: ungqimba lwe-enamel luhlanganiswa ku-820–930 °C ku-0.25–0.45 mm.
Ungqongqoshe wezokuthenga osebenza ngesicaciso sethangi ngezinye izikhathi uhlangana nomugqa obhalwe ngokuthi 2C2F noma 3C3F bese ewushaya indiva noma awudlulisele kungqongqoshe wokugqwala sengathi igama lezinto ezisetshenziswayo. Akulona igama lezinto ezisetshenziswayo; isifinyezo sendlela uhlelo lokumboza olwakhiwe futhi lwaqedwa ngayo, futhi livela emndenini ofanayo wokubhalwa kokumboza okusetshenziswa ensimbi yesakhiwo, izinto zokumboza zezimboni kanye nezokumboza zokuvikela amapayipi. Ukuqonda lokhu kubalulekile ngoba umehluko phakathi kohlelo lwezingxenye ezimbili nohlelo lwezingxenye ezintathu uwumehluko phakathi kokumboza okuhlala isikhathi eside nokumboza okudinga ukulungiswa kusenesikhathi, futhi ngoba ikhodi efanayo ingasho izinto ezihlukene kubahluzi abahlukene.
Ukufunda ikhodi: izingxenye, amajazi nokuqedwa
Isakhiwo sombhalo walezi zimpawu yisona esiveza umongo. Kulolu hlu lwezifinyezo zokugcoba, inombolo yokuqala isho ukuthi zingaki izingxenye ezakha uhlelo — uhlelo lwezingxenye ezimbili luyisisekelo kanye nesikhuthazi noma i-resin kanye ne-ejenti yokuqinisa, uhlelo lwezingxenye ezintathu lwengeza into yesithathu njenge-primer, isibopho kanye ne-topcoat noma i-epoxy kanye nohlelo oluphezulu lwe-polyurethane. Uhlamvu noma izinhlamvu ezilandelayo zikhomba isigaba sokugcoba, futhi izinombolo kanye nohlamvu olulandela zichaza ifilimu noma ukuqedwa: ukuthi ingxenye iyi-primer, i-intermediate noma i-topcoat, ukuthi ifilimu iwumkhiqizo we-fusion noma we-fusion-bonded, kanye nokuqedwa kwendawo. Ngakho-ke u-2C2F ufundeka njengohlelo lwezingxenye ezimbili olunezingubo ezimbili noma izigaba ezimbili zefilimu kanye nokucaciswa kokuqedwa, futhi u-3C3F ufundeka njengohlelo lwezingxenye ezintathu olunezigaba ezintathu. Lesi sifinyezo siwusizo emdwebeni futhi asiwusizi embuzweni wethenda, ngoba ikhodi ikutshela ukuma kohlelo kodwa ayikutsheli ngamakhemikhali.
Lapho lezi zikhodi zivela khona kuphrojekthi yethangi
I-notation yokumboza ivela endaweni lapho umnikazi efuna ukuthi i-lining ichazwe ngaphambi kokuba ithangi licashunwe. I-specification yethangi ejwayelekile izobala uhlelo lokumboza lwangaphandle, uhlelo lwe-lining lwangaphakathi kanye nohlelo lwe-immersion noma lwe-splash-zone, ngayinye inekhodi yayo, bese kube seyengeza imininingwane ekhodi eyodwa engasoze iyithwale: ukujiya kwe-dry film thickness ngama-micrometre, izinga lokulungiselela ingaphezulu, isimo sokusetshenziswa, isikhathi sokuphola kanye nendlela yokuhlola. Ku-fusion-bonded epoxy lining, i-specification kufanele isho uhlobo lwe-powder, ububanzi be-film thickness obungu-180–280 µm, ireferensi ye-AWWA C550 kanye nomphumela we-salt spray ongaphezu kwamahora angu-4000. Ethangini le-glass-fused-to-steel, i-coating schedule ithathelwa indawo i-enamel schedule: izinga lokushisa le-fusion elingu-820–930 °C, ukujiya kwesendlalelo okungu-0.25–0.45 mm, amandla akaliwe angaphezu kuka-3,450 N/cm², ukuhlolwa kwe-spark ye-1500 V DC kuphaneli ngayinye, ukuqedwa kwengaphezulu okungaphansi kwe-Ra 0.8 µm kanye ne-pH envelope engu-1–14.
Ingozi yokwehluleka efihlwa yikhodi
Ikhodi engenazinombolo iyinkinga yangempela, hhayi ikhodi ngokwayo. Izinhlobo ezimbili zokwehluleka ezibonakala ezindongeni zangaphakathi zamathangi ezicaciswe yikhodi kuphela ukufakwa kwefilimu encane kakhulu kanye nokulungiselelwa kwendawo okungafanele. Uhlelo lwezingxenye ezimbili olusetshenziswa engxenyeni yobukhulu obucacisiwe ensimbi engazange ihlanjululwe ngesihlambululi esiqhululayo sifinyelele ezingeni lokuhlanzeka elishiwoyo luzobonakala lulungile ohlelweni kodwa luhluleke ngokushesha ekusebenzeni, okuyindlela iphrojekthi egcina ngayo ithangi elifanayo lilungiswa kabili eminyakeni eyisithupha. Ukuzivikela kungokwenqubo: funa iphepha ledatha lokumboza elinokulingana kwezingxenye, ububanzi bogqinsi lwefilimu eyomile ecacisiwe, iwindi lokumboza ngaphezulu kanye nesimo sokuphinda kumbozwe; funa izinga lokulungiselelwa kwendawo kanye nokujula kweprofayili kushiwo; funa indlela yokuhlola amaholide noma inhlansi ibizwe ngegama; futhi funa ukuhlolwa kwengqondo yobugqinsi befilimu eyomile yasensimini ngesikhathi sokusetshenziswa nasesikhathini sokunikezela. Lezo zinto ezine ziguqula ikhodi ibe isicaciso esiphoqelekayo.
