Pamalonda oyambira azitsulo zokhala ndi malata, kugudubuzika kozizira kumayendetsedwa ndi malata otentha, ndipo magawo otentha ndi osowa kwambiri. Ndiye, pali kusiyana kotani pakati pa zinthu zamalata zotentha ndi zozizira? Tiyeni tifotokoze mwachidule mbali zotsatirazi:

1. Mtengo
Chifukwa chosowa ndondomeko otaya poyerekeza ndi ozizira adagulung'undisa magawo, otentha kuviika galvanizing otentha adagulung'undisa magawo ali ndi mtengo wotsika kuposa ozizira anagubuduza, makamaka chifukwa cha mtengo quenching ndi ozizira anagubuduza, pamene njira zina zofanana.
2. Makhalidwe abwino
Chifukwa chakuti gawo lapansi lotentha limangokhala ndi pickling ya acid, passivation, ndi quenching kuchotsa zotsalira pamwamba, pamwamba pake ndi yosasalala, ndi kumamatira kwa nthaka wosanjikiza kumakhala bwino. Makulidwe a zokutira ndi olemera kuposa 140/140a/m2, koma makulidwe ake siwofanana ndi a kugudubuza kozizira, chifukwa zigawo zambiri za zinc ndi zokhuthala, komanso kusintha kwa makulidwe a zinki sikuli kofanana. Palibe kusiyana kwakukulu pakuchita kwathupi, ndipo ngakhale kusintha kwina kwa magwiridwe antchito ndikwabwino pamagalimoto ozizira
3. Ntchito zazikulu
Pamagalimoto otentha, mapepala achitsulo opangira malata nthawi zambiri amagwiritsidwa ntchito popanga zida zomangira zomwe zili ndi zofunikira zochepa zapamtunda koma zolimba zolimba komanso makulidwe ake chifukwa kulondola kwawo kwathunthu ndi mawonekedwe ake si abwino ngati a mbale zoziziritsa zoziziritsa kukhosi. makulidwe amayenera kukhala okulirapo kuposa azitsulo ozizira okulungidwa;
Mwachitsanzo, zida zapakhomo monga makina ochapira okha ndi mafiriji, zida zamkati zamagalimoto, zida zamoto, ziwiya zamabasi, ma slabs oponyedwa mu situ, njanji zapamsewu, zitsulo zozizira, ndi zina zambiri.
Chifukwa cha mtengo wotsika wazitsulo zotentha zotentha, komanso kutsagana ndi kupita patsogolo kwaukadaulo, makulidwe azinthu ndi zitsanzo zikuchulukiranso, ndipo kufunikira kukukulirakulira pang'onopang'ono.
4. Chitsanzo
Chitsanzo chofala cha mbale yachitsulo yotentha ndi DD51DZ.HD340LADZ HR340LA HR420IA HR5501A, etc.:
Tsamba lozizira lopiringizidwa ndi malata likufanana ndi DC51D Z.HC340LAD ZHC340LA, HC420LA, HC550LA, etc.:
Palinso mtundu womwe suli wachindunji pazigawo zoziziritsa kuzizira kapena zotenthedwa, monga DX51D Z, zomwe nthawi zambiri zimatha kuwonedwa ngati mapepala okulungidwa otentha.
