1.What yog qhov zoo ntawm galvanized lauj tshib muab piv rau cov hlau stainless tshib?
Tus nqi qis dua: Stainless hlau (xws li 304, 316) muaj cov khoom siv raw khoom zoo, thaum Galvanized tais yog raws li cov roj carbon hlau. Cov txheej txheem corrosion yog txhim kho tsuas yog los ntawm cov txheej txheem galvanizing, thiab tag nrho cov nqi dej tag nrho tuaj yeem txo qis (xws li cov khoom siv dej thiab tso dej thiab cov pipelines).
Kev ua haujlwm qis nyuaj nyuaj: stainless hlau muaj lub hardness siab, thiab txiavreator cov cuab yeej siv (xws li cov khoom siv hluav taws xob (xws li cov phiaj xwm me me, cov phiaj xwm me me).
Qhov hnyav sib dua: qhov ntom ntawm cov roj carbon hlau me me qis dua li ntawm cov hlau stainless. Raws li tib cov lus qhia tshwj xeeb, Galvanized lauj kaub yog qhov sib dua thiab yooj yim los nqa thiab nruab, tshwj xeeb tshaj yog nyob rau ib puag ncig muaj siab.
2.Qhov dab tsi yog qhov zoo ntawm galvanized lauj tshib muab piv rau cov thawv hlau tais?
Cuam tshuam ntau dua corrosion: dog dig carbon steel yog nquag pleev xim rau corrosion tiv thaiv corrosion, uas muaj cov nqi txij nkawm; Thaum lub galvanized txheej (zinc) txwv tsis pub muaj rowing los ntawm kev tiv thaiv cov roj av (zinc yog ntau dua li cov kav dej khov kho (xws li cov kav dej hauv av)
The surface is more beautiful and maintenance-free: The surface of carbon steel elbows is prone to oxidation and blackening, and additional anti-rust treatment is required; Qhov saum npoo ntawm galvanized tais muaj ib qho nyiaj-grey xim hlau luster, uas tuaj yeem tswj kev zoo nkauj rau lub sijhawm ntev uas tsis muaj xim ntxiv, txo cov haujlwm ntawm kev kho tom qab.
3.Qhov yog qhov zoo ntawm galvanized lauj tshib sib piv kom cam khwb cia hlau luj tshib?
Lub zog siab dua thiab kev cuam tshuam zoo dua: cam khwb cia hlau luj (xws li cov hlau nplaum ua kom nruj (xws li cov kav dej sib tsoo (xws li cov kav dej khov kho hauv av) thiab tuaj yeem tiv thaiv cov kav dej siab (xws li cov kav dej khov kho hauv av).
Kev sib txuas tau yooj yim tshaj plaws: cam khwb cia hlau luj tshib feem ntau txuas nrog cov thom khwm, thiab cov kauj ruam teeb tsa yog cumbersome; Galvanized elbws txhawb vuam, kev sib txuas flange thiab lwm txoj kev, uas tuaj yeem hloov kho kom haum rau cov raj hluav taws xob sib txawv, cov kav dej hauv tsev siab).
Qhov hnyav dua thiab kev txhim kho siab: nyob rau hauv tib cov lus qhia tshwj xeeb, qhov nyhav ntawm cam khwb cia hlau luj yog li 1.5 ~ 2 zaug ntawm galvanized lauj kaub. Tsheb thauj mus los thiab kev teeb tsa yog lub sijhawm thiab siv zog ua haujlwm. Galvanized lauj tshib yog qhov tsim nyog rau cov kev sib cav loj loj thiab tsim kho sai.
4.What yog qhov zoo ntawm galvanized lauj tshib sib piv rau yas luj (PVC \/ PE, thiab lwm yam)?
Muaj zog zog kuj: Yas lauj kaub<1.0MPa; while galvanized elbows (especially hot-dip galvanizing) can withstand 1.6~4.0MPa high pressure, suitable for high-pressure systems such as industrial pipelines and fire water supply.
Cov Ntshav Zoo Tshaj Plaws: Yas Hnab Quav Muaj Cov Kub Hluav Taws Kub (PVC qhov kub kub tsis kam<60℃, PE temperature resistance <80℃), and cannot be used for hot water or steam pipes; galvanized elbows can withstand high temperatures of 150~200℃ (depending on the substrate and coating), and are suitable for heating and air-conditioning hot water pipes.
Siv hluav taws xob ntev dua: Plastics yog nquag nquag rau kev laus (ultraviolet rays, oxidation), thiab lub neej pabcuam hauv kev qhib ib puag ncig huab cua yog li 10 ~ 15 xyoos; Kub-DIP galvanized tais tuaj yeem siv rau 20 ~ 30 xyoo nyob rau hauv kev saib xyuas tsim nyog, haum rau lub sijhawm ntev (xws li cov kav dej ntev (xws li cov kav dej ntev (xws li cov kav dej hauv nroog ntev).
5.Qhov dab tsi yog qhov tseem ceeb ntawm galvanized lauj kaub?
Corrosion Kuj: Zoo dua cov hlau lauj kaub thiab cam khwb cia hlau luj, tab sis tus nqi qis dua), haum rau ib puag ncig corrosive (xws li dej thiab huab cua huab cua).
Tus nqi: qis dua cov hlau tsis xeb thiab cov hlau lauj tshib tshib, siab dua li cov hlau thiab yas lauj tshiav, nrog cov nqi tsim nyog.
Lub zog thiab siab Kuj: siab dua li cam khwb cia hlau thiab yas lauj tshib tshiav, kom zoo rau nruab nrab thiab kub siab xa hluav taws xob tshuab.
Kev sib haum xeeb: Kev ua yooj yim, muaj kev sib txuas tau yooj yim, zoo dua li cam khwb cia hlau luj, piv rau cov hlau stainless tshib.
Muaj feem xyuam nrog cov xwm txheej: Ntsuas kom muaj kev ua tau zoo, kev lag luam, kev lag luam, kev lag luam, kev ua yeeb yam nrog nruab nrab corrosion, nruab nrab thiab siab ntev.
