Ho roala zinki

Zinc ke ts'ebetso ea metallurgical reaction.Ho ea ka pono ea microscopic, mokhoa oa ho chesa metsi a chesang ke tekanyo e 'meli e matla, tekanyo ea mocheso le tekano ea phapanyetsano ea zinki.Ha tšepe ea tšepe e qoelisoa hoo e ka bang 450mokelikeli oa zinki o qhibilihisitsoeng, mocheso oa kamore ea mokelikeli oa zinki o monyang mocheso oa sesebelisoa, o fihlang ka holimo ho 200, ho sebelisana ha zinki le tšepe ho ile ha hlaka, zinki, tšepe li kenella ka holimo.Ha mocheso oa "workpiece" o ntse o atamela mocheso oa zinki e qhibilihisitsoeng, bokaholimo ba mosebetsi bo entsoe ka karolo e fapaneng ea zinki tšepe alloy layer, sebopeho sa hierarchical sa coat ea zinki, ka nako e telele, kholo ea sekhahla se fapaneng sa alloy plating se hlahisa lebelo le fapaneng la lebelo.Ho ea ka pono e kholo, ts'ebetso ea ts'ebetso e kaholimo e qoelisoa ka zinki e metsi, ho belisoa ha zinki ho etsahala ha zinki, karabelo ea tšepe butle-butle e leka-lekana, bokaholimo ba zinki bo kokobela butle-butle.Mosebetsi o entsoe.ka holim'a zinki, mocheso oa workpiece o theoleloa butle-butle ho ea ka tlase ho 200, karabelo e ile ea emisoa ke zinki, tšepe, chesang qoelisa masenke barbotage e na le botenya ikemiselitse.

Botenya ba lintho tse ka sehloohong tsa ho roala zinki: karolo ea tšepe ea motheo, ho ba le tšepe ea holim'a tšepe, tšepe ea lintho tse sebetsang tsa silicon le phosphorus le kabo, khatello ea ka hare ea tšepe, geometry ea mosebetsi, mokhoa oa ho futhumatsa o chesang. .Hona joale litekanyetso tsa machaba le Sechaena li arotsoe ka likarolo ho ea ka botenya tšepe, botenya ba zinki barbotage botenya le ho hula ea sebakeng seo e lokela ho fihla botenya tšoanang, ho fumana hore zinki barbotage anticorrosion tshebetso.Botenya ba tšepe bo fapaneng ba sesebelisoa, ho fihlela tekano ea mocheso, le tekano ea phapanyetsano ea zinki ka linako tse fapaneng, botenya bo hlahisoang bo fapane.Botenya bo boholo ba maemo a ho roala bo thehiloe holim'a mochini oa boiphihlelo ba galvanizing tlhahiso ea indasteri, botenya ba lehae ba botenya ba zinki bo nkoa e le kabo e sa lekanang ea litlhoko tsa ts'ireletso ea kutu le ts'ireletso e hlokahalang boiphihlelo.Ka hona, litekanyetso tsa ISO, litekanyetso tsa ASTM, litekanyetso tsa JIS le litekanyetso tsa Sechaena tlhokahalo ea botenya ba zinki e fapane hanyane, e ts'oana haholo.

Botenya ba lesela la zinki bo lekanya ts'ebetso ea likarolo tsa anticorrosion plating.Bakeng sa limilimithara tse 3 ka tlase ho holim'a poleiti e tšesaane ea tšepe e boreleli, ho thata ho fumana sekoahelo se teteaneng tlhahiso ea indasteri, ho phaella moo, ha e lumellane le botenya ba tšepe ea tšepe ea zinki 'me e tla ama matla a ho khomarela a ho roala le. substrate le ponahalo ea boleng bo holimo.A barbotage teteaneng tla etsa hore barbotage ponahalo ea kaba, bonolo peeling, plating likarolo ke ke mamella ho thulana ka tshebetso ya ho sebetsana le tlhomamiso.Haeba ho na le lisebelisoa tse ngata tse sebetsang tsa silicon le phosphorus, tlhahiso ea indasteri e bile thata haholo ho roala, e leng karolo ea silicon ea tšepe e nang le tšusumetso pakeng tsa mokhoa oa ho hōla oa zinki-iron alloy layer.
