Kubuda-kwe-line annealing kunoreva kuti recrystallization annealing yekupisa kana kutonhora yakakungurutswa ndiro inoitwa muchoto chepasi chemhando yeannealing kana chevha yemhando yekuvharisa moto isati yapinda mumutsara wewaya inopisa, kuitira kuti pasave nekubatisa mukati memagetsi. line.Iyo ndiro yesimbi inofanirwa kuchengetedza yakachena inoshanda pamusoro pesimbi yakachena, isina maokisi uye imwe tsvina, isati yapisa dip galvanizing.Nenzira iyi, iyo annealed surface oxide sheet inotanga kubviswa nenzira ye pickling, uye yozoputirwa nemucheka we zinc chloride kana musanganiswa weammonium chloride uye zinc chloride solvent yekudzivirira, kuitira kudzivirira ndiro yacho kubva kune oxidized zvakare.
Iyi nzira inowanzove yekushandiswa kwendiro inopisa yakakungurutswa seyakagadzirwa, iyo annealed simbi ndiro inotanga kutumirwa kumusangano wekunhonga, ine sulfuric acid kana hydrochloric acid kubvisa pamusoro pesimbi pepa okisijeni inopisa galvanizing nzira.Mushure mekunhonga, ndiro yesimbi inopinda pakarepo mutangi kuti inyove uye kumirira galvanized, izvo zvinogona kudzivirira reoxidation yesimbi ndiro.Mushure mekunhonga, kuchenesa mvura, kusvina yakaoma, kuomesa, muhari ye zinc, tembiricha yakachengetedzwa pa445-465 ℃.
Kupisa dip galvanizing inobva yazorwa oiri uye chromed.Hunhu hwekupisa-galvanized sheet hunogadzirwa nenzira iyi hunovandudzwa zvakanyanya kana huchienzaniswa neiyo nenzira yekunyorovesa yemagetsi.Inongokosha pakugadzirwa kwediki-diki.Kuenderera mberi kwekugadzira galvanizing mutsara kunosanganisira akatevedzana e pretreatment maitiro, senge alkali degreasing, hydrochloric acid pickling, kugeza mvura, solvent coating, kuomesa, nezvimwewo, uye ndiro yepakutanga inoda kuvharwa muchoto chekuvharira usati wapinda mumutsara wegalvanizing.
