Mzere Wophimba Ufa wa Zipangizo Zapadera
Chingwe Chophikira Ufa cha Zipangizo Zapadera -- Maersk Container Coating Project
Mu pulojekiti yopangira zotengera za Maersk, mzere wopanga wapangidwira zotengera zokhazikika ndi zida zazikulu zachitsulo, zomwe zimayang'anira zofunikira zazikulu monga kukula kwa ntchito yayikulu, kupanga kokhazikika kwa batch, komanso kukana dzimbiri kwambiri.
Kuti ipirire malo ovuta a m'nyanja—kuphatikizapo mchere wambiri, chinyezi, komanso kuwonekera panja kwa nthawi yayitali—mzerewu wakonzedwa bwino kutengera ukadaulo wamba wopaka ufa.
Pulojekitiyi ikugwiritsa ntchito njira ya "kukonza bwino zinthu zisanakonzedwe + kuphimba ufa wa electrostatic + kuchiritsa bwino kwambiri," kuphatikiza ndi dongosolo la "chotengera cha unyolo choyikidwa pansi + chosinthira chokweza chomwe chingakonzedwe". Kapangidwe kameneka kamalola kusamutsa kokha pakati pa kukweza, kuchiza zisanakonzedwe, ndi njira zina zotsatizana, kuchepetsa kulowererapo kwamanja pamene mukutsimikizira kuti kupanga zinthu kukhazikika komanso kugwira ntchito mosalekeza.
Kuyenda kwa Njira
1. Njira Yokwezera ndi Kutumiza
Mu polojekitiyi, kuphatikiza kwa makina onyamulira unyolo okhala pansi ndi makina osinthira okonzedwa kumagwiritsidwa ntchito kuti akwaniritse kukweza kwamagulu ndi kusamutsa zokha ku magawo okonzekera chithandizo ndi e-coating.
Kudzera mu kayendetsedwe kolondola kosamutsa, ma workpiece amayenda bwino pakati pa machitidwe osiyanasiyana otumizira, kuchepetsa kusatsimikizika komwe kumachitika chifukwa cha kugwiritsidwa ntchito pamanja pomwe akutsimikizira kuti kupanga kukuyenda bwino, kuyendetsa bwino ntchito, komanso kugwira ntchito modalirika.
2. Kuchiza Pasadakhale & Kuchiza Pamwamba
Pazinthu zazikulu zachitsulo zomwe zili ndi ziwiya, njira yophatikizira yopopera ndi kumiza imagwiritsidwa ntchito.
Gawo lochotsa mafuta limagwiritsa ntchito njira yotenthetsera madzi otentha mwachindunji, kusunga kutentha kwa ndondomeko mkati mwa 40–50°C. Izi zimaletsa kutentha kwambiri komwe kumachitika pamalopo ndipo zimathandizira kuti ntchito yogwirira ntchito ikhale yokhazikika pa ntchito zonse ziwiri komanso malo osambira oyeretsera, zomwe zimapangitsa kuti ntchito yophimba ikhale yodalirika.
Kuphatikiza apo, gawo lokonzekera limakhala ndi njira yotsukira madzi yolimbana ndi madzi komanso njira yobwezeretsanso madzi, kuphatikizapo kutsuka madzi otsutsana ndi madzi pakati pa matanki ochotsa mafuta ndi matanki akuluakulu ochotsera mafuta, komanso kutsuka madzi otsutsana ndi madzi otsutsana ndi madzi. Kapangidwe kameneka kamachepetsa kwambiri kugwiritsa ntchito madzi pamene kakuwonjezera kugwiritsa ntchito mankhwala, zomwe zimapangitsa kuti pakhale kusunga mphamvu komanso kugwira ntchito bwino.
Pofuna kupititsa patsogolo kusinthasintha kwa kupanga, mzerewu wapangidwa kuti ugwirizane ndi makontena wamba komanso malo otayira zinyalala. Mphamvu yake imasungidwanso kuti igwiritsidwe ntchito popanga utoto wopanda phosphate wopanda madzi, zomwe zimathandiza kupanga mitundu yosiyanasiyana ya zinthu ndikuwonjezera kugwiritsa ntchito mzere wonse.
3. Kuuma
Pambuyo pokonza zinthuzo, zinthuzo zimalowa mu makina owumitsira mpweya wotentha kuti zichotse chinyezi chotsalira pamwamba.
Mwa kukonza bwino ma profiles a kutentha ndi kufalikira kwa mpweya, kuumitsa kofanana kumachitika m'malo onse a zigawo zazikulu za kapangidwe kake, kupewa zolakwika zokhudzana ndi chinyezi pakuphimba zinthu zomwe zingachitike pambuyo pake.
4. Kuphimba Ufa
Gawo lopaka utoto limagwiritsa ntchito ukadaulo wopaka utoto wa electrostatic powder pamodzi ndi kupopera kokha komanso kukhudza ndi manja kuti likwaniritse zofunikira zopaka utoto wa nyumba zazikulu komanso zovuta za chidebe.
Kudzera mu kapangidwe kabwino ka mfuti yopopera ndi magawo amagetsi, kuphimba kofanana kumachitika pamalo akuluakulu. Malo ofunikira monga m'mphepete ndi mipata yolumikizira imalimbikitsidwa kudzera mu kukhudza ndi manja kuti zitsimikizire kuti makulidwe a chophimbacho ndi magwiridwe antchito oteteza.
Dongosolo lopaka utoto limagwirizanitsidwa ndi kayendedwe ka dongosolo loperekera utoto, kusunga mtundu wokhazikika wa utoto komanso kugwiritsa ntchito ufa wambiri panthawi yopanga mosalekeza.
5. Kukonza Ufa
Pambuyo popaka utoto, zinthu zogwirira ntchito zimalowa mu uvuni waukulu wophikira kuti zigwiritsidwe ntchito kutentha.
Pogwiritsa ntchito njira yoyendera mpweya wotentha yokhala ndi kutentha koyenera komanso ma profiles ophikira, utoto wa ufa umasungunuka bwino ndipo umalumikizana bwino, zomwe zimapangitsa kuti ukhale wolimba bwino, wamphamvu, komanso wokana dzimbiri womwe ungagwiritsidwe ntchito nthawi yayitali m'madzi.
6. Kuziziritsa & Kutumiza
Pambuyo pozizira, zinthu zogwirira ntchito zimadutsa m'malo ozizira pogwiritsa ntchito kuzizira kwachilengedwe kapena kuzizira kokakamiza kuti chophimbacho chikhazikike.
Zipangizo zomalizidwa zimasamutsidwa kudzera mu makina onyamulira katundu kupita kumalo otulutsira katundu. Makonzedwe osinthasintha okweza ndi kutsitsa katundu amathandiza kusamalira bwino kukula ndi kuchuluka kwa zinthu zosiyanasiyana.
