Qhov sib txawv ntawm Stainless Hlau thiab Galvanized Steel

GNEE Steel Kub Dipped Galvanized Steel Chev

Plain carbon steel tseem yuav xeb yooj yim heev nyob rau hauv feem ntau ib puag ncig yog tias tsis tiv thaiv. Vim li no, muaj ntau txoj hauv kev hlau tau hloov kho los tiv thaiv corrosion. Ob qhov kev daws teeb meem nrov yog siv cov hlau tsis muaj steel lossis galvanized hlau. Thaum ob lub steels tiv thaiv xeb thiab corrosion, muaj qhov sib txawv tseem ceeb ntawm lawv uas yuav tsum tau nkag siab.

Stainless hlau yog dab tsi?

Stainless hlau muaj peev xwm tiv taus corrosion vim tias muaj cov alloying ntxiv hauv nws cov tshuaj pleev ib ce. Txawm hais tias cov pa roj carbon steel muaj feem ntau ntawm cov hlau thiab cov pa roj carbon monoxide, cov hlau tsis muaj hlau muaj ntau ntxiv ntawm chromium los pab nws tiv thaiv corrosion. Cov chromium, thiab qee zaum lwm yam alloying ntsiab lus, yog ntxiv rau cov hlau tsis muaj steel thaum lub sij hawm pib melting txheej txheem, ua ntej nws yuav raug tsim rau hauv tej yam ntxwv.

Dab tsi yogGalvanized hlau?

Galvanized steel yog ib hom hlau uas tau coated hauv ib txheej zinc uas pab tiv thaiv cov hlau hauv qab los ntawm xeb. Cov txheej no feem ntau yog nyias nyias, feem ntau ntsuas hauv txhiab tus ntiv tes lossis microns. Txhawm rau tsim cov hlau galvanized, zinc txheej feem ntau yog ntxiv zoo tom qab melting, refining, thiab shaping ntawm steel phaj los yog ntawv. Qee lub sij hawm nws tseem ua tiav tom qab cov txheej txheem tsim tau ua rau nws xws li khoov lossis vuam.

Yuav ua li cas Stainless hlau tiv thaiv corrosion?

Stainless hlau resists corrosion vim yog ntxiv chromium (thiab qee zaum lwm yam ntxiv). Corrosion tshwm sim ntawm cov hlau thaum cov hlau los ntawm cov hlau raug tso cai ua ke nrog cov pa oxygen hauv nws qhov chaw ib puag ncig. Cov chromium hauv stainless hlau tuaj yeem tiv thaiv qhov no vim nws sib xyaw nrog cov pa oxygen thiab tsim cov txheej txheem chromium oxide passive. Cov txheej ntawm chromium oxide no tiv thaiv kev tsim cov hlau oxide, (tseem hu ua xeb), nyob rau ntau lub sijhawm, tsuav yog cov ntsiab lus chromium ntawm cov hlau zoo txaus. Cov qib sib txawv ntawm cov hlau tsis muaj steel tsim thiab txiav txim siab qhov yuav tsum tau muaj ntawm chromium thiab lwm yam alloying ntsiab lus, uas pab qhia txog qib ntawm corrosion kuj.

Galvanized Steel Resistant Corrosion li cas?

Galvanized steel resists corrosion vim zinc txheej npog lubcarbon hlau. Cov txheej zinc ua haujlwm ob lub hom phiaj:

Nws tiv thaiv cov pa oxygen los ntawm kev sib cuag nrog cov hlau, yog li txo qhov muaj peev xwm ntawm corrosion.

Txawm hais tias cov zinc txheej yuav tsum muaj kev puas tsuaj me me thiab nthuav tawm cov hlau me me rau cov cua, cov zinc nyob ze ntawm cov txheej txheej yog ntau dua li cov hlau. Qhov no ua rau cov zinc feem ntau nyiam cov pa molecule dua li cov hlau, uas tiv thaiv xeb los ntawm cov hlau.

Qhov sib txawv ntawm Stainless Hlau thiab Galvanized Steel

Stainless hlau feem ntau muaj zoo corrosion-resistant zog dua galvanized hlau. Yog hais tias cov hlau tsis muaj khawb, nws tseem tuaj yeem tiv thaiv corrosion nyob ib ncig ntawm thaj chaw cuam tshuam. Txawm li cas los xij, yog tias cov zinc txheej ntawm galvanized steel puas lawm, nws tuaj yeem tso cov pa roj carbon monoxide hauv qab thiab tsis muaj zog. Thiab vim tias galvanized steel feem ntau dipped nyob rau hauv zinc nyob rau hauv cov nplooj ntawv loj ces txiav mus rau qhov loj me, cov npoo qhov chaw txiav tawm yog sab laug ua rau nws muaj peev xwm ua rau xeb tshwm sim.

Stainless hlau kuj feem ntau suav hais tias ua kom zoo nkauj dua li cov hlau galvanized, raws li stainless feem ntau muaj ci iab, zoo li xim xim, piv rau cov qauv dull-grey ntawm galvanized steel. Txawm li cas los xij, stainless hlau kuj tseem kim dua li cov hlau galvanized.

Kev siv ntawm Stainless Hlau

Stainless hlau feem ntau yog siv rau hauv daim ntawv thov uas qhov kev pheej hmoo ntawm corrosion yog ib qho kev txhawj xeeb loj thiab tsis tso cai. Cov cheeb tsam siv rau stainless hlau muaj xws li:

• Cov khoom siv ua zaub mov
• Pharmaceutical manufacturing khoom
• Aerospace engine Cheebtsam
• Cov khoom siv hauv chav ua noj
• Qee hom fasteners

Kev siv ntawm Galvanized Steel

Galvanized steel yog siv rau cov ntawv thov uas tsis xav tau corrosion, tab sis qhov me me tuaj yeem tso cai thiab kev zoo nkauj tsis muaj kev txhawj xeeb ntau. Daim ntawv thov rau galvanized steel muaj xws li:

• Cov kav dej ua haujlwm
• Automotive Cheebtsam
• Qee hom fasteners
• Qauv kab teeb
• Hlau txee
• railing
• Kev taug kev
• Cov cim tsheb
• Cov ncej hluav taws xob
