Ulwazi oluthile oluhlobene lwe-hot dip galvanizing

Izindaba

Ifekthri ekhiqiza idiphu eshisayo: ungqimba olushisayo lwediphu ngokuvamile lungaphezu kwama-35m, ngisho lufinyelela ku-200m, olunokufakwa okuhle kwediphu elishisayo elishisayo, ukumbozwa okuhlangene futhi akukho okuhlanganisiwe kwemvelo. Njengoba sonke sazi, indlela yokumelana nokugqwala kwe-zinc emkhathini ihlanganisa ukuvikelwa kwemishini nokuvikelwa kwe-electrochemical. Ngaphansi kwezimo zokugqwala komkhathi, kunamafilimu okuvikela e-ZnO, Zn (OH) 2 kanye ne-zinc carbonate eyisisekelo ebusweni bongqimba lwezinc, anciphisa ukugqwala kwe-zinc ngezinga elithile. Uma le filimu evikelayo (eyaziwa nangokuthi ukugqwala okumhlophe) yonakaliswa, kuzokwakhiwa ifilimu entsha
Ifekthri eshisayo ye-dip galvanizing: ukumelana nokugqwala kwe-atmospheric dip galvanizing kuya kwesisekelo sensimbi kungcono kunokwe-electro galvanizing.
Ifekthri ekhiqiza idiphu eshisayo: ukujiya kongqimba olunamanzi olushisayo lwediphu lwensimbi lunquma ukusebenza kokunqanda ukugqwala kwensimbi enezikhala. Umsebenzisi angakhetha ukujiya kwe-zinc coating ephakeme noma ephansi kunezinga elijwayelekile. Kumameshi ensimbi azacile anobuso obushelelezi kanye nogqinsi olungaphansi kuka-3mm, kunzima kubakhiqizi bokufaka ama-galvanizing ashisayo ukuze bathole ukunamathela okuqinile ekukhiqizeni kwezimboni. Ngaphezu kwalokho, ubukhulu be-zinc coating obungahambisani nobukhulu be-mesh yensimbi buzothinta ukunamathela phakathi kwe-coating kanye ne-substrate kanye nekhwalithi yokubukeka yokugqoka. Ukumboza okuningi kuzoholela ekubukekeni okumaholo, ukuxebuka kalula kokugqoka, futhi igridi yensimbi ayikwazi ukumelana nokushayisana ngesikhathi sokuphatha nokufakwa. Uma kukhona izakhi ezisebenzayo ezifana ne-silicon ne-phosphorus ezintweni zokusetshenziswa ze-steel mesh, kunzima ukuthola ama-coatings amancane ekukhiqizeni kwezimboni. Lokhu kungenxa yokuthi okuqukethwe kwe-silicon ensimbi kuthinta imodi yokukhula yongqimba lwengxubevange phakathi kwe-zinc ne-iron, okuzokwenza ungqimba lwe-zinc iron alloy lukhule ngokushesha futhi lubhekane nongaphezulu, okuholela ekuqineni, i-Matt namandla angenamandla okubopha. kwe-coating.
