Electric galvanized:
Simbi iri nyore kuita ngura mumhepo, mvura kana ivhu, kana kutoparara zvachose.Kurasikirwa kwesimbi kwegore negore nekuda kwekuora kunokwana 1/10 yesimbi yose yakabuda.Mukuwedzera, kuitira kuti upe pamusoro pezvigadzirwa zvesimbi uye zvikamu basa rinokosha, uchivapa chimiro chekushongedza, zvinowanzobatwa ne electro-galvanizing.
① Musimboti:
Sezvo zinc isiri nyore kusiyanisa mumhepo yakaoma, mumhepo ine hunyoro, pamusoro inogona kuburitsa yakanyanya dense base-type carbonate film, iyo inogona kunyatso chengetedza mukati kusisina ngura.
② Maitiro ekuita:
1. Iyo zinc yekuputira yakakora, ine makristasi akanaka, kufanana uye isina porosity, uye yakanaka yekudzivirira ngura;
2. Zinc layer inowanikwa ne electroplating inenge yakachena, uye inoparadza zvishoma nezvishoma mumhute yeasidhi, alkali, nezvimwewo, uye inogona kunyatsodzivirira substrate yesimbi;
3. Iyo zinc coating inopfuudzwa ne chromic acid kuti iite chena, ine mavara, yemauto yakasvibira, nezvimwewo, iyo yakanaka uye yekushongedza;
4. Nemhaka yokuti zinc coating ine ductility yakanaka, inogona kuumbwa nekutonhora kunotonhora, kukunguruka, kupfugama, nezvimwewo pasina kukuvadza kuvhara.
③ Sarudzo yekushandisa:
Nekuvandudzwa kwekugadzirwa kwesainzi uye tekinoroji, minda inobatanidzwa muindasitiri ye electroplating yakawedzera kuwanda.Parizvino, kushandiswa kweelectro-galvanization kwapararira kune akasiyana madhipatimendi ekugadzira uye ekutsvagisa.
Hot galvanized:
Ⅰ.Muchidimbu
Munzira yekuputira yeakasiyana akachengetedzwa simbi matrix, inopisa dip yakanaka kwazvo.Iri munzvimbo iyo zinc iri mvura, mushure mefizikisi yakaoma kunzwisisa, kemikari, kwete chete yakakora yakachena zinc layer isina kungoputirwa pasimbi, asiwo zinc-ferrous layer.Iyi nzira yeplating haina kungoita corrosion kuramba hunhu hwemagetsi galvanization, asiwo nekuda kweiyo zinc iron alloy layer.Iyo inewo kupikisa kwakasimba kune electroplated zinc.Naizvozvo, iyi nzira yekuisa yakanyatsokodzera kune yakasimba corrosive nharaunda yakadai seyakasiyana-siyana yakasimba acid, alkaline mhute.
Ⅱ.Musimboti:
Iyo inopisa-dip galvanized layer ndeye zinc mune yakanyanya tembiricha mvura, uye inoumbwa nematanho matatu:
1. Iron-based surface inopedzwa neine zinc solution kuti iite zinc-ferrous phase;
2. Zinc ions mualloy layer inowedzera kuparadzirwa kune substrate kuita zinc iron intercollation layer;
3. pamusoro peiyo alloy layer yakavharwa mu zinc layer.
Ⅲ.Performance maitiro:
(1) Iine yakakora yakakora yakachena zinc layer inovhara pamusoro pesimbi, iyo inodzivirira kubata kwesimbi matrix kubva kune chero ngura mhinduro kuchengetedza simbi matrix kubva mukuora.Mumamiriro ekunze, pamusoro pe zinc layer inoumba hutete hwakatetepa uye hwepedyo zinc oxide layer, iyo yakaoma kunyungudika mumvura, saka simbi matrix inotamba imwe mhedzisiro yekudzivirira.
(2) Iine iron-zinc alloy layer, yakasanganiswa nedense, mugungwa remunyu humex mhepo uye maindasitiri mamiriro airatidza kusaita ngura;
(3) Sezvo musanganiswa wacho wakasimba, zinc-iron yakanyungudutswa, ine yakasimba kupfeka kuramba;
(4) Sezvo zinc ine ductility yakanaka, alloy layer yakanyatsobatanidzwa neboka resimbi, saka zvikamu zvinopisa zvinopisa zvinogona kutonhora, kukungurutswa, brushed, curved, nezvimwe zvakadaro pasina kukuvadza kupfeka;
(5) Mushure mekupisa kupisa kwesimbi finisse, yakaenzana nekurapa kweannealing, iyo inogona kunyatso kuvandudza michina yesimbi matrix, kubvisa kushushikana kwesimbi molding welding, iyo inobatsira pakushandura nhengo yesimbi.
(6) Pamusoro pezvimedu mushure mekupisa galvanization inopenya uye yakanaka.
(7) Iyo yakachena zinc layer ndiyo yakanyanya purasitiki-yepurasitiki-yakaputirwa galvanized layer mune inopisa galvanized, iyo iri padyo ne pure zinc, ductility, saka inochinjika.
Ⅳ.Kuwanda kwekushandisa:
Kushandiswa kwehot-dip ghanely kusimudzira kweindasitiri nekurima.Naizvozvo, hot-dip ghared zvigadzirwa maindasitiri (senge makemikari emidziyo, kugadzira mafuta, kuongorora mugungwa, chimiro chesimbi, kutakura magetsi, kuvaka ngarava, nezvimwewo), zvekurima (zvakadai se: kusaswa), zvivakwa (zvakadai semvura uye gasi kuendesa, waya set Tube, scaffolding, imba, nezvimwewo), bhiriji, chekufambisa, nezvimwe zvakashandiswa mumakore akati wandei apfuura.
Sezvo zvinopisa-dip galvanized zvigadzirwa zvine chitarisiko chakanaka, yakanaka corrosion resistance performance, huwandu hwayo hwekushandisa huri kuramba huchiwedzera.
