Chiyambi ndi Kuyerekeza kwa Zophimba za Mapaipi a Chitsulo Chofala, kuphatikizapo Mafuta Akuda, 3PE, FPE, ndi ECET – ROYAL GROUP

1. Chophimba Mafuta Akuda: Njira Yothandiza Popewa Dzimbiri
Pofuna kuthana ndi mavuto okhudzana ndi dzimbiri a mapaipi achitsulo wamba, Royal Steel Group imagwiritsa ntchito ukadaulo wa Black Oil coating kuti ipereke chitetezo choyambirira pa mapaipi achitsulo atsopano. Pogwiritsa ntchito njira yopopera madzi, chophimbachi chimafika pa makulidwe olamulidwa bwino a ma microns 5-8, kuteteza bwino mpweya ndi chinyezi, kupereka chitetezo chabwino kwambiri cha dzimbiri. Chifukwa cha njira yake yokhwima, yokhazikika komanso yotsika mtengo, chophimba cha Black Oil chakhala njira yodzitetezera yokhazikika pazinthu zonse za mapaipi achitsulo a Gulu, kuchotsa kufunikira kwa zosowa zina za makasitomala. Chimagwiritsidwa ntchito kwambiri m'mapulojekiti osiyanasiyana omwe amafuna kupewa dzimbiri.

2. FBE Coating: Kugwiritsa Ntchito Mwanzeru Ukadaulo wa Epoxy Wosungunuka ndi Moto

Mu ntchito zomwe zimafuna chitetezo chapamwamba kwambiri cha dzimbiri, ukadaulo wa Royal Steel Group wa FBE (hot-solved epoxy) umawonetsa ubwino wapamwamba. Njirayi, yochokera pa chitoliro chopanda kanthu, choyamba imachotsedwa dzimbiri mwamphamvu pogwiritsa ntchito SA2.5 (sandblasting) kapena ST3 (manual descaling) kuti zitsimikizire kuti pamwamba pa chitolirocho pali ukhondo ndi kuuma kwake zikugwirizana ndi miyezo yodziwika. Kenako chitolirocho chimatenthedwa kuti chigwirizane mofanana ndi ufa wa FBE pamwamba pake, ndikupanga chophimba cha FBE chimodzi kapena ziwiri. Chophimba cha FBE cha magawo awiri chimawonjezeranso kukana dzimbiri, kusintha malo ovuta komanso ovuta kugwira ntchito komanso kupereka chotchinga chodalirika cha mapaipi amafuta ndi gasi.

3. Chophimba cha 3PE: Chitetezo Chokwanira Chokhala ndi Kapangidwe ka Zigawo Zitatu

Yankho la chophimba la Royal Steel Group la 3PE limapereka chitetezo chokwanira kudzera mu kapangidwe kake ka magawo atatu. Gawo loyamba ndi ufa wa epoxy resin wosinthika mtundu, womwe umayika maziko olimba otetezera dzimbiri. Gawo lachiwiri ndi guluu wowonekera bwino, womwe umagwira ntchito ngati gawo losinthira ndikuwonjezera kumamatira pakati pa zigawo. Gawo lachitatu ndi chophimba chozungulira cha polyethylene (PE), chomwe chimawonjezera mphamvu ya chophimbacho komanso kukana kukalamba. Yankho la chophimba ichi likupezeka m'mitundu yonse yotsutsana ndi kuyendayenda komanso yosatsutsana ndi kuyendayenda, yokonzedwa kuti igwirizane ndi zosowa za makasitomala, yomwe imapereka kusintha kosinthika ku zochitika zosiyanasiyana za polojekiti. Imagwiritsidwa ntchito kwambiri m'mapaipi otumizira kutali komanso mapaipi aukadaulo a boma.

4. Kuphimba kwa ECTE: Njira Yotsika Mtengo Yogwiritsira Ntchito Zobisika ndi Zomizidwa

Pa ntchito zapadera monga zogwiritsidwa ntchito m'madzi ndi m'madzi, Royal Steel Group yakhazikitsa njira ya Epoxy Coal Tar Enamel Coating (ECTE). Chophimba ichi, chozikidwa pa epoxy resin coal tar enamel, chimateteza dzimbiri bwino komanso chimachepetsa ndalama zopangira, zomwe zimapatsa makasitomala njira yotsika mtengo. Ngakhale kuti zophimba za ECTE zimaphatikizapo kuipitsa chilengedwe panthawi yopanga, Gululo lakonza njira zake zopangira, lili ndi zida zonse zochizira chilengedwe, komanso kutulutsa mpweya woipa, zomwe zimapangitsa kuti pakhale mgwirizano pakati pa kukwaniritsa zofunikira za polojekiti ndikukwaniritsa maudindo azachilengedwe. Izi zapangitsa kuti ikhale njira yabwino kwambiri yophikira mapulojekiti monga mapaipi amafuta obisika ndi maukonde amadzi apansi panthaka.

5. Kuphimba kwa Fluorocarbon: Katswiri pa Chitetezo cha UV pa Milu ya Miyala
Pa ntchito monga ma piel piles, omwe amakumana ndi kuwala kwamphamvu kwa UV kwa nthawi yayitali, ukadaulo wa Royal Steel Group wa Fluorocarbon coating ukuwonetsa zabwino zapadera. Chophimbachi cha zigawo ziwiri chimakhala ndi zigawo zitatu: choyamba ndi epoxy primer, zinc-rich primer, kapena zinc-rich primer yopanda maziko, zomwe zimapangitsa maziko olimba kuti asagwe dzimbiri. Gawo lachiwiri ndi epoxy micaceous iron intermediate coat yochokera ku kampani yotchuka ya Sigmacover, yomwe imawonjezera makulidwe a chophimba ndikuletsa kulowa. Gawo lachitatu ndi fluorocarbon topcoat kapena polyurethane topcoat. Ma fluorocarbon topcoat, makamaka omwe amapangidwa kuchokera ku PVDF (polyvinylidene fluoride), amapereka UV yabwino kwambiri, nyengo, komanso kukana kukalamba, kuteteza bwino maziko a mulu kuti asagwe ndi mphepo ya m'nyanja, kupopera mchere, ndi kuwala kwa UV. Gululi limagwiranso ntchito ndi makampani otchuka opaka utoto monga Hempel, posankha ma primer awo ndi ma midcoat kuti atsimikizire bwino mtundu wonse wa zophimbazo ndikupereka chitetezo cha nthawi yayitali ku zomangamanga zam'madzi monga madoko ndi madoko.

6. Zophimba Zamkati za Mapaipi a Madzi: Chitsimikizo cha Ukhondo cha IPN 8710-3
