Pankhani ya momwe choviikidwa kanasonkhezereka zitsulo chitoliro, ndondomeko yotentha-kuviika galvanizing zotsatira mu metallurgical chomangira pakati nthaka ndi zitsulo ndi mndandanda wa aloyi osiyana chitsulo-zinki. Chingwe chokokera chotenthetsera chimagwira ntchito motere:
1. Chitsulo chimatsukidwa pogwiritsa ntchito njira yothetsera vutoli. Izi zimachotsa mafuta / mafuta, dothi, ndi utoto.
2. Njira yoyeretsera caustic imatsukidwa.
3. Chitsulocho amazifutsa mu njira acidic kuchotsa mphero sikelo.
4. The pickling solution ndi kuchapidwa.
5. Flux, nthawi zambiri zinc ammonium chloride imagwiritsidwa ntchito kuchitsulo kuletsa makutidwe ndi okosijeni pamalo oyeretsedwa akakumana ndi mpweya. The flux amaloledwa kuti ziume pa zitsulo ndi zothandizira mu ndondomeko ya madzi zinki wetting ndi kutsatira zitsulo.
6. Chitsulocho chimaviikidwa mu bafa yosungunuka ya zinki ndikusungidwa pamenepo mpaka kutentha kwachitsulo kumagwirizana ndi kusamba.
7. Chitsulocho chimakhazikika mu thanki yozimitsa kuti muchepetse kutentha kwake ndikuletsa zochita zosayenera za zokutira zomwe zangopangidwa kumene ndi mlengalenga.
Mwaukadaulo, malata ndi njira yokutira chitsulo ndi chitsulo chosanjikiza cha zinki pomiza chitsulo mu bafa la zinki wosungunuka pa kutentha kozungulira 840 °F (449 °C). Zinc (Zn) ikakhala mumlengalenga, zinc (Zn) yoyera imakumana ndi okosijeni (O2) kupanga zinc oxide (ZnO), yomwe imakhudzidwanso ndi mpweya woipa (CO2) kupanga zinc carbonate (ZnCO3), imvi nthawi zambiri, yamphamvu kwambiri. zinthu zomwe zimateteza zitsulo pansi kuti zisawonongeke nthawi zambiri. Nthawi zambiri, chitoliro choviikidwa chamalata chimakhala ndi mtengo wapamwamba wachitsulo kuposa mitundu ina ya chitoliro chomwe chikugwiritsidwa ntchito chifukwa cha kukwera mtengo kwake pamsika.
Pazogwiritsa ntchito, monga machitidwe ena oteteza dzimbiri, galvanizing imateteza kwambiri zinthu zachitsulo pochita ngati chotchinga pakati pa chitoliro chachitsulo ndi mlengalenga. Komabe, zinki ndi chitsulo chochuluka cha electronegative poyerekeza ndi chitsulo. Ichi ndi chikhalidwe chapadera cha galvanizing. Makamaka, pamene zokutira zamalata zawonongeka ndipo chitsulo chachitsulo chikuwonekera mumlengalenga, zinki zimatha kupitiriza kuteteza chitsulo kupyolera mu galvanic corrosion. Kuphatikiza apo, ngati zokutira uku kwakhala kukanda kapena kung'ambika, chitetezo chachiwiri cha zinc chimafunika kuteteza chitsulo ndi galvanic. Mu mphero, makulidwe a zinki amalamuliridwa ndi kuchuluka kwa nthawi yomwe gawo lililonse limamizidwa mu bafa yosungunuka ya zinki komanso liwiro lomwe limachotsedwa. Mawu oti “kuviika kawiri” amatanthauza mbali zazikulu kwambiri kuti sizingalowe mu ketulo yopangira malata ndipo ziyenera kumizidwa mbali imodzi imodzi. Sichikutanthauza makulidwe owonjezera opaka. Monga katswiri zitsulo chitoliro wopanga ku China, ife tadzipereka kupanga mitundu yosiyanasiyana ya chitoliro zitsulo ntchito zanu. Kuti mudziwe zambiri, mutha kulumikizana nafe nthawi iliyonse.
