1. Kushanda scope
Zvikumbiro zvakakosha zvekupisa-kunyura kwakakurudziramapepa ari muminda yakaita semotokari, midziyo yemumba, kuvaka engineering, michina yemagetsi, zvigadzirwa zvemagetsi, uye indasitiri yemagetsi.
2. Chikonzero chikuru chekudonha kwe zinc layer
Izvo zvekutanga zvinhu zvinoita kuti zinc layer iwire pasi zvinosanganisira kugadzirwa kwezvinhu zvakasvibirira uye kugadzira, pamwe nekusaenderana kugadzirwa uye kugadzirisa.Nekuda kweiyo oxidation yepamusoro, silicon makomisheni, yakakwira oxidation mamiriro uye inodzivirira gasi dova muchikamu cheNOF chezvakagadzirwa, zvisinganzwisisike chiyero chemafuta emhepo, yakaderera hydrogen kuyerera, kupinza kweokisijeni muchoto, kuderera kwakadzika kwesimbi yesimbi inopinda muhari. , tembiricha yakaderera yeNOF chikamu chevira, kusakwana kwemafuta evaporation, low aluminium content mu zinc pot, fast unit speed, kusakwana kuderedza, nguva pfupi yekugara mumvura ye zinc, uye coating gobvu.Kugadzirisa kusapindirana kunosanganisira kusapindirana kwekukotama radius, kupfeka mold, kukwesha, mold clearance yakakura kana idiki zvakanyanya, kushaikwa kwekutsika mafuta ekuzora, uye nguva yakareba yekushanda ye mold isati yagadziriswa kana kuchengetedzwa.
3. Zvinhu zvakakosha zvinokonzera ngura chena ndezvi
(1) Kutadza kuita, kusakwana kana kusaenzana passivation firimu ukobvu;
(2) Kumusoro hakuna kuzora mafuta;
(3) Yakasara mwando pamusoro pesimbi inotonhora yakakungurutswa;
(4) Passivation isina kunyatsoomeswa;
(5) Panguva yekufambisa kana kuchengetedza, mwando unodzoka kana kunaya kunonyorovesa:
(6) Nguva yekuchengetedza yezvigadzirwa zvakapedzwa yakarebesa;
(7)Hot dip galvanized sheetirikusangana kana kuchengetwa pamwe chete nezvimwe zvinhu zvinoparadza zvakaita seasidhi yakasimba nemaalkali.
Ngura chena inogona kushanduka kuita makwapa matema, asi mavara matema anogona kunge asina kungokonzerwa ne ngura chena, senge makwapa matema.
4. Yakakura inobvumirwa kuchengetedza nguva
Kana kuzora mafuta, kurongedza, kuchengetera zvinhu, uye zvinhu zvikaitwa panguva yakakodzera, zvimwe zvigadzirwa zvinogona kuchengetwa kwerinopfuura gore, asi zviri nani kuishandisa mumwedzi mitatu.Kana pasina mafuta, nguva ipfupi kudzivirira mhepo oxidation inokonzerwa nekuchengetedza kwenguva yakareba.Nguva chaiyo yekuchengetedza inofanira kubva pane chigadzirwa chinoenderana nechigadzirwa chaicho.
5. Basic Principles yeZinc Layer Maintenance
Munzvimbo dzinotyisa dzechisikigo, zingi inoisa pamberi kuparadzira ngura pamusoro pesimbi, nekudaro kuchengetedza hwaro hwesimbi.Panyaya yekushorwa nekuora, iyo zinc layer inogadzira imwe firimu inodzivirira kubva kune yakaoma kudzivirira kukurumidza mhepo oxidation, inonoke mwero wekuora, uye inogona kubhuroshwa ne zinc poda pendi panguva yekugadzirisa kudzivirira kuparara kwesimbi uye kuve nechokwadi hunhu hwemuviri uye. kuchengetedza maitiro e data.
6. Basic Principles of Passivation
Iyo Chromium trioxide passivation mhinduro yekupisa dip galvanized sheet inogona kuburitsa bhero rakaumbwa firimu.Iyo trivalent chromium mu saturated solution passivation mhuri yakaoma kunyungudika mumvura yakaoma, zvimiro zvayo zvemuviri hazvina kupenya, uye zvine maitiro ekuumba.Iyo hexavalent chromium mumhuri ye passivation inonyungudika mune yakasimba electrolyte, iyo inogona kuva nebell shaped effect kana passivation film inokwenya, uye ine kuporesa kwebell shaped film.Naizvozvo, kune imwe nhanho, iyo passivation firimu inogona kudzivirira chiutsi kana nyoro inotonhora gasi kubva pakarepo corrosa inopisa-dip galvanized sheet, ichitamba basa rekugadzirisa.
7. Nzira yekugadzira corrosion resistance performance
Pane nzira nhatu dzekuyedza corrosion resistance yehot-dip galvanized sheets:
(1) Kuedza kupfapfaidza munyu;(2) Kuedza kutonhora kwemvura;(3) Corrosion miedzo.
