Kupaka kwa zinc

Zinc ndi njira ya metallurgical reaction.Kuchokera pamalingaliro ang'onoang'ono, njira yopangira dip galvanizing ndi magawo awiri amphamvu, kutentha kwapakati komanso kusinthana kwachitsulo cha zinki.Pamene zitsulo workpiece kumizidwa pafupifupi 450Zinc madzi osungunuka, kutentha kwa chipinda kutentha kwa zinki kutentha kwa workpiece, kufika pamwamba pa 200, kuyanjana kwa zinki ndi chitsulo kunakhala koonekeratu, zinki, chitsulo chimalowa pamwamba.Pamene kutentha kwa workpiece pang'onopang'ono kuyandikira kutentha kwa zinki wosungunuka, workpiece pamwamba popangidwa ndi gawo losiyana la nthaka chitsulo aloyi wosanjikiza, dongosolo hierarchical wa nthaka ❖ kuyanika, ndi nthawi yaitali, kukula kwa osiyanasiyana aloyi plating wosanjikiza panopa osiyanasiyana liwiro.Kuchokera pazambiri, ntchito ya pamwamba ndondomeko workpiece kumizidwa mu madzi nthaka, nthaka madzi otentha kumachitika pamene nthaka, chitsulo anachita pang'onopang'ono bwino, nthaka pamwamba pang'onopang'ono bata.Workpiece imapangidwapaZinc pamwamba, kutentha kwa workpiece kumatsitsidwa pang'onopang'ono mpaka pansi pa 200, anachita anaimitsidwa ndi nthaka, chitsulo, otentha kuviika kanasonkhezereka ❖ kuyanika ali makulidwe mtima.

The makulidwe a nthaka ❖ kuyanika zinthu zikuluzikulu: m'munsi zitsulo chigawo, pamwamba roughness wa zitsulo, chitsulo cha yogwira zinthu pakachitsulo ndi phosphorous okhutira ndi kugawa, nkhawa mkati zitsulo, workpiece geometry, otentha-kuviika galvanizing ndondomeko. .Mfundo panopa mayiko ndi Chinese anawagawa zigawo malinga ndi makulidwe zitsulo, makulidwe a nthaka ❖ kuyanika makulidwe ndi kujambula m'deralo ayenera kufika makulidwe lolingana, kudziwa nthaka ❖ kuyanika anticorrosion ntchito.Zosiyanasiyana zitsulo makulidwe a workpiece, kukwaniritsa kufanana matenthedwe, ndi zinki ion kuwombola mgwirizano nthawi zosiyanasiyana, chifukwa ❖ kuyanika makulidwe osiyana.Avereji makulidwe a muyezo ❖ kuyanika zachokera limagwirira galvanizing zinachitikira kupanga mafakitale, makulidwe m'dera la nthaka makulidwe ❖ kuyanika makulidwe amatengedwa m'njira yosiyana kugawa ❖ kuyanika ndi dzimbiri chitetezo zofunika zinachitikira.Chifukwa chake, miyezo ya ISO, miyezo ya ASTM, miyezo ya JIS ndi miyezo yaku China yofunikira ya makulidwe a zinki ndizosiyana pang'ono, chimodzimodzi.

Kuchuluka kwa zokutira zinki kumatsimikizira magwiridwe antchito a anticorrosion plating.Pakuti 3 mm m'munsimu woonda zitsulo mbale pamwamba ndi yosalala, n'kovuta kuti ❖ kuyanika wandiweyani mu kupanga mafakitale, kuwonjezera, si commensurate ndi makulidwe a zitsulo zinki plating makulidwe ndipo zimakhudza adhesion mphamvu ❖ kuyanika ndi gawo lapansi ndi mawonekedwe opaka utoto.A ❖ kuyanika wandiweyani adzachititsa ❖ kuyanika maonekedwe a akhakula, mosavuta peeling, plating mbali sangathe kupirira kugundana ndondomeko akuchitira ndi unsembe.Ngati pali zitsulo zogwira ntchito za silicon ndi phosphorous, kupanga mafakitale kwakhala kovuta kwambiri ❖ kuyanika, komwe kuli zitsulo zachitsulo zomwe zimakhudzidwa ndi kukula kwa zinki-chitsulo aloyi wosanjikiza.
