Pama mbale a goli otentha a dip omwe amagwiritsidwa ntchito m'mizere yotumizira magetsi, kukhazikitsidwa kokhazikika kwa njira yotenthetsera-dip galvanizing imatsimikizira moyo wantchito ya malonda ndi momwe chitetezo chimagwirira ntchito. Nkhaniyi ipereka chidziwitso chatsatanetsatane kuchokera ku mfundo za ndondomeko, ndondomeko zazikulu, mfundo zazikulu zoyendetsera khalidwe, ubwino wa ndondomeko, ndi ndondomeko zotsatiridwa ndi malonda akunja.
Kutentha-dip galvanizing ndikogwirizana kwambiri ndi zitsulo. Pamene pamwamba pa goli lachitsulo loyeretsedwa lamizidwa mu zinki wosungunuka pafupifupi madigiri 450 , chitsulo (Fe) mu gawo lapansi lachitsulo ndi zinki (Zn) mu zinki wosungunula zimasakanizika mosalekeza ndi kusakanikirana, kupanga zosanjikiza zitatu{4}}zokhala ngati malata. Kuchokera mkati, zigawo izi ndi:
Iron-Zinc Alloy Layer (Internal Layer): Chomangirira ku chitsulo gawo lapansi, makamaka wopangidwa ndi Fe3Zn10 ndi FeZn7, ndi wandiweyani ndipo amamatira mwamphamvu kwambiri, zomwe zimapatsa chitsimikizo cholimba kuti chisachite dzimbiri ndi anti{4}}kusewela kwa malata.
Zinc-Iron Alloy Layer (Middle Layer): Wopangidwa ndi FeZn13, ali ndi makulidwe apakatikati ndipo amaphatikiza kulimba ndi kulimba.
Zinc Woyera (Wosanjikiza Wakunja): Kuphimba gawo lakunja, ndi lofewa komanso lodumphira, kupanga filimu yoteteza ya zinc oxide pamwamba. Kuphatikiza apo, pakachitika zokopa zapamalo, zimapereka chitetezo chosalekeza kudera lophwanyidwa kudzera muchitetezo chachitetezo cha anodic.
Pa mbale za Hot Dip galvanized goli, makulidwe onse a magawo atatu-ayenera kuyendetsedwa mosamalitsa kuti apitirire 65μm. Pogwiritsa ntchito-zofunika kwambiri, makulidwe ake akhoza kuonjezedwa kufika pa 85μm kuti akwaniritse zofunikira za kupopera mchere wambiri komanso malo owononga kwambiri.
Kapangidwe ka Hot Dip Galvanized Yoke Plates kuyenera kutsata njira yofananira ndikuwongolera - kutentha-dip galvanizing - posttreatment - kuyang'anira. Zina mwa izo, pretreatment ndi sitepe yofunikira yomwe imatsimikizira mtundu wa galvanizing ndipo imakhudza mwachindunji kumamatira ndi kufanana kwa zokutira.
Kuthira mafuta: Gwiritsani ntchito mankhwala ochotsera mafuta a alkaline kuti munyowe pa madigiri 60-80 kwa mphindi 5-10, kapena gwiritsani ntchito-kutsuka popopera mphamvu kwambiri kuti muchotse madontho a mafuta opopera, oletsa dzimbiri, fumbi ndi mafuta pamwamba pa mbale yolumikizira. M'mphepete mwa mbale ya goli ndi makoma amkati mwa mabowo a bolt ndi malo omwe amakhala ndi mafuta otsalira, omwe amafuna nthawi yopopera mankhwala kapena kuyeretsa mothandizidwa ndi akupanga.
Kutsuka ndi kuyeretsa madzi: Muzimutsuka kudzera mu thanki yoyamba ndi yachiwiri yochapira kuti muchotse chotsalira chochotsera mafuta. Njirayi iyenera kuwonetsetsa kuti palibe madzi ochuluka kapena otsalira m'mabowo a bawuti.
Kukhetsa ndi kuchotsa dzimbiri: Gwiritsani ntchito hydrochloric acid potola, kumiza m'malo otentha kwa mphindi 10-15 kuti muchotse oxide sikelo, dzimbiri, ndi rolling oxide layer pajoko plate. Kwa sikelo yokulirapo ya okosijeni, nthawi ya pickling imatha kuonjezedwa moyenerera, koma kuwongolera mwamphamvu kumafunika kupewa kutola mopitirira muyeso, zomwe zingayambitse kuuma kwa pamwamba ndikuchepetsa kumamatira kwa zokutira.
Kutsuka madzi ndi kusalowerera ndale: Imizereni mu thanki ya alkaline neutralization kuti muchepetse zinthu zotsalira za acidic, kuonetsetsa kuti pasakhale ndale. Makoma amkati a mabowo a bawuti ayenera kutsukidwa bwino kuti zotsalira za asidi zisapangitse matuza muzitsulo za malata.
Drying and preheating: Dry at 120-150℃ for 10-15 minutes to completely remove surface moisture. The surface must be free of water stains and oxidation; otherwise, the galvanized layer may show signs of blistering or exposure to oxidized material. Defects such as those mentioned above; Zinc immersion: The zinc immersion temperature is strictly controlled at 445-460℃. The immersion time is adjusted according to the thickness of the plate. When the thickness is ≤6mm, the immersion time is 1-2 minutes. When the thickness is >6mm, nthawi yomiza ndi mphindi 2-3. Kuziziritsa: Gwiritsani ntchito kuziziritsa kwa mpweya kapena kuziziritsa nkhungu yamadzi kuti muzizire mpaka kutentha. Pakuzizira, pewani kugundana pakati pa Mbale wa Hot Dip Galvanized Yoke kuti mupewe kukwapula pa zokutira.
Pazitsulo zotumizidwa kunja kwa Hot Dip Galvanized Yoke, njira zopangira ziyenera kukwaniritsa miyezo yoyenera ndi zofunikira za certification pamsika womwe mukufuna; apo ayi, sangathe kulowa msika. Monga akatswiri opanga, kampani yathu imaika patsogolo khalidwe lazogulitsa; chonde omasuka kugula.
