Kub-dip Galvanizing txheej txheem rau E355 Hlau Yeeb Nkab: Zoo thiab Txheej Zoo
Kub-dip galvanizing yog tus qauv kub rau kev tiv thaiv corrosion ntawm cov kav hlau, thiab cov txheej txheem rau E355 Kub-dip Galvanized Steel Yeeb Nkab ua raws cov txheej txheem nruj, kev ua haujlwm tau zoo los xyuas kom meej cov txheej txheej tuab, muaj zog adhesion thiab ua haujlwm ntev. Tsis zoo li electro-galvanizing, kub-dip galvanizing tsim metallurgical daim ntawv cog lus ntawm zinc txheej thiab E355 steel substrate, tsim ib tug multi- txheej tiv thaiv txheej txheem uas tiv thaiv chipping, khawb thiab tev thaum lub sij hawm thauj mus los, installation thiab siv txhua hnub.
Cov txheej txheem galvanizing rau E355 cov kav dej suav nrog plaub theem tseem ceeb: kev kho saum npoo av, txheej txheej flux, kub -dip immersion thiab txias tiav. Txhua theem yog saib xyuas kom zoo kom tshem tawm xeb, roj thiab impurities, kom ntseeg tau tias zinc txheej adheres zoo kawg nkaus rau cov hlau nto. Qhov siab - kub immersion (450-}460 degree) tso cai rau cov zinc molten nkag mus rau cov hlau lub microstructure, tsim kom muaj ib tug ruaj barrier uas thaiv corrosive hais xws li ya raws, ntsev, acids thiab muaj kuab paug. Cov txheej txheem no tsis yog tsuas yog txuas rau cov yeeb nkab txoj kev pab cuam lub neej tab sis kuj txo cov nqi txij nkawm rau cov haujlwm ntev.
Ib qho ntawm qhov zoo tshaj plaws ntawm E355 Kub-dip Galvanized Steel Pipe yog nws cov txheej txheem zoo ib yam. Zinc txheej thickness ua tau raws li cov qauv thoob ntiaj teb, nrog cov kev pabcuam zoo sib xws thoob plaws cov yeeb nkab sab hauv thiab sab nrauv, suav nrog cov xov kawg thiab cov pob qij txha. Qhov kev tiv thaiv zoo li no tshem tawm cov chaw tsis muaj zog uas ua rau muaj kev xeb, ua rau cov yeeb nkab haum rau sab nraum zoov, hauv av thiab dej hiav txwv qhov chaw uas cov kav hlau zoo tib yam yuav deteriorate sai.
