Kufotokozera Kwachidule:

PRETREATMENT DRUM & HEATING ndi chida chomwe chimagwiritsidwa ntchito popanga mafakitale kuti azipangira zinthu zopangira. Nthawi zambiri imakhala ndi mbiya yozungulira yopangira mankhwala komanso makina otenthetsera. Panthawi yogwira ntchito, zopangirazo zimayikidwa mu mbiya yozungulira yopangira chithandizo ndikutenthedwa ndi makina otenthetsera. Izi zimathandiza kusintha mawonekedwe akuthupi kapena mankhwala azinthu zopangira, zomwe zimapangitsa kuti zikhale zosavuta kuzigwira panthawi yopangira. Zida zamtunduwu nthawi zambiri zimagwiritsidwa ntchito m'mafakitale, kukonza chakudya, mankhwala ndi mafakitale ena kuti apititse patsogolo kupanga bwino komanso mtundu wazinthu.

Pretreatment ndi njira yofunika kwambiri yopangira galvanizing yotentha, yomwe imakhudza kwambiri ubwino wa zinthu zopangira malata. Kutentha koyambirira kumaphatikizapo: degreasing, kuchotsa dzimbiri, kutsuka madzi, plating aid, kuyanika njira, etc.
Pakalipano, m'makampani opangira moto wapakhomo, thanki yamtengo wapatali ya granite imagwiritsidwa ntchito kwambiri. Poyambitsa umisiri wotsogola wa dip dip galvanizing ku Europe ndi America, akasinja otolera a PP (polypropylene)/PE (polyethylene) akugwiritsidwa ntchito mochulukira mumizere yopangira malata.

Kutengera ndi kuuma kwa banga lamafuta pamtunda wa workpiece, degreasing imachotsedwa mwanjira zina.

Tanki yothira mafuta, thanki yochapira madzi ndi thanki yothandizira plating nthawi zambiri imakhala yopangidwa ndi konkriti, ndipo ina imapangidwa ndi zinthu zomwezo ngati thanki yonyamula.

Kutentha koyambirira

Gwiritsani ntchito kutentha kwa zinyalala za gasi wonyezimira kutenthetsa akasinja onse ochiritsira, kuphatikiza kutsitsa,picklingndi plating wothandizira. Dongosolo la kutentha kwa zinyalala limaphatikizapo:
1) Kuyika kwa ophatikiza kutentha exchanger mu chitoliro;
2) Seti imodzi ya PFA yosinthira kutentha imayikidwa kumapeto kwa dziwe lililonse;
3) Njira yamadzi yofewa;
4) Kuwongolera dongosolo.
Kutentha koyambirira kumakhala ndi magawo atatu:
① Chosinthira kutentha kwa gasi
Malingana ndi kuchuluka kwa kutentha komwe kumayenera kutenthedwa, chophatikizira chophatikizira kutentha kwa flue chimapangidwa ndi kupangidwa, kotero kuti kutentha kukhoza kukwaniritsa zofunikira zotentha. Ngati kokha kutentha zinyalala za chitoliro sangathe kukumana Kutentha kutentha kufunika kwa chisanadze mankhwala, ya ng'anjo otentha mpweya akhoza kuwonjezeredwa kuonetsetsa chitoliro mpweya voliyumu.
Chojambulira kutentha chimapangidwa ndi chitsulo chosapanga dzimbiri chosagwira kutentha kapena chitoliro chachitsulo chosasunthika 20 # chokhala ndi zokutira zatsopano za infrared nano kutentha kwambiri zopulumutsa mphamvu zolimbana ndi dzimbiri. Mphamvu yoyamwitsa kutentha ndi 140% ya kutentha komwe kumatengedwa ndi zida wamba zotenthetsera kutentha.
② PFA chosinthira kutentha
③Kuyanika uvuni
Zinthu zonyowa zikalowa mubafa la zinki, zimachititsa kuti madzi a zinki aphulike ndikuphulika. Choncho, pambuyo plating thandizo, kuyanika ndondomeko ayeneranso anatengera kwa mbali.
Nthawi zambiri, kutentha kwa kuyanika sikuyenera kupitirira 100 ° C ndipo sikuyenera kukhala kotsika kuposa 80 ° C. Apo ayi, zigawozo zikhoza kuikidwa mu dzenje loyanika kwa nthawi yaitali, zomwe zingayambitse kuyamwa kwa zinc chloride mu mchere mosavuta. filimu yothandizira plating pamwamba pa zigawozo.
