Ntawm cov txheej txheem teeb duab ntawm galvanized steel hlau xaim
Thawj plating thiab tom qab ntawd kos duab txheej txheem:
Txhawm rau txhawm rau txhim kho qhov ua tiav ntawm cov ntawv galvanized steel hlau, cov txheej txheem ntawm cov hlau xaim hlau los ntawm cov hlau hluav taws, galvanizing thiab tom qab ntawd kos duab mus rau cov khoom tiav hu ua plating ua ntej thiab tom qab ntawd txheej txheem yog nqus. Cov txheej txheem ntws ntws mus yog: cov hlau xaim-hlau lead quenching-galvanizing-kos duab-tiav lawm hlau xaim. Cov txheej txheem ntawm thawj daim hlau tom qab kos duab yog cov txheej txheem luv tshaj plaws ntawm txoj kev galvanized steel hlau nqus txheej txheem, uas tuaj yeem siv rau kub dip galvanizing lossis electro-galvanizing tom qab kos duab. Tom qab kub-dip galvanizing, cov yam ntxwv ntawm cov hlau tsis xeb zoo dua li cov hlau tsis xeb tom qab kos thawj zaug, thiab cov zinc txheej tau ua ntom ntom thiab tiv taus tom qab kos tom qab electro-galvanizing. Ob leeg tuaj yeem muab tau nyias thiab nyias zinc txheej, txo kev siv zinc, thiab txo cov load ntawm cov kab galvanizing.
Tom qab cov txheej txheem plating:
Cov txheej txheem txheej txheem tom qab nruab nrab plating yog: cov hlau tsis muaj hlau-txhuas quenching-thawj daim duab-galvanizing-theem teeb duab-tiav cov hlau tsis muaj hlau. Cov yam ntxwv ntawm ib nrab-plating tom qab kos duab yog tias cov hlau lead hlau tsis xeb hlau yog kos ib zaug thiab tom qab ntawd galvanized thiab tom qab ntawd kos ob zaug rau cov khoom tiav. Lub galvanizing yog nruab nrab ntawm ob qho, yog li nws hu ua 'nruab nrab plating. Cov zinc txheej ntawm cov hlau xaim tsim los ntawm nruab nrab plating thiab kos duab yog tuab tshaj qhov ntawm plating thiab kos duab. Tom qab kub-dip galvanizing, teeb duab tom qab plating tuaj yeem muab cov txheej txheem siab tag nrho (ntawm cov hlau lead quenching mus rau cov khoom tiav), uas yog qhov zoo dua li cov kav hlau tom qab thawj zaug plating thiab tom qab ntawd teeb duab.
Txoj kev sib xyaw plating:
Txhawm rau los ua lub zog loj kawg (3000 N / mm2) galvanized hlau xaim," hybrid plating" cov txheej txheem siv. Cov txheej txheem cov txheej txheem ntws yog raws li hauv qab no: cov hlau lead quenching-thawj teeb duab-pre-galvanizing-theem pib kos duab-kawg galvanizing-tertiary yog nqus (kos duab qhuav) -dej lub tank teeb ntawm cov hlau ua tiav lawm. Cov txheej txheem saum toj no tuaj yeem tsim ultra-high-lub zog galvanized steel hlau nrog cov pa roj carbon 0.93-0.97%, taub 0.26 hli, lub zog 3921 N / mm2. Thaum lub sijhawm daim duab, zinc txheej tiv thaiv thiab ua kom lub ntsej muag ntawm cov hlau tsis xeb, thiab tsis muaj lub xov hlau tawg tshwm sim thaum kos duab
