** 1. Puas yog cov hlau puas xeb? **
Yog lawm, feem ntau hlau siv xeb. Rust yog hom tshwj xeeb ntawm kev corrosion uas tshwm sim thaum hlau, reacts nrog oxygen thiab noo noo nyob rau hauv huab cua los tsim hlau oxide. Txij li cov hlau yog ib qho alloy ua cov hlau, nws yog qhov raug rau kev xeb tshwj tsis yog nws tiv thaiv lossis tsim tshwj xeeb los tiv thaiv corrosion.
** 2. Cov hlau twg tsis tuaj yeem xeb? **
Hom hlau uas tsis tuaj yeem hu ua ** Stainless Hlau **. Stainless hlau muaj qhov feem pua siab ntawm chromium (feem ntau tsawg kawg yog 10.5%). Qhov chromium reacts nrog oxygen los ua ib qho nyias nyias, pom tsis tau, thiab tiv thaiv txheej ntawm chromium oxide rau saum npoo. Cov txheej no txwv tsis pub oxygen thiab noo noo ntawm mus txog ntawm cov hlau hauv qab, ua rau nws tiv taus xeb. Lwm yam hom zoo li Galvanized steel (txheej nrog zinc) yog cov xeb zoo heev {{}} tiv taus tab sis tsis tag nrho cov kev tiv thaiv tab sis tsis tag nrho cov mob.
** 3. Nws puas muaj kev nyab xeeb rau Weld Rusty hlau? **
Vuam rusty steel yog ** tsis pom zoo thiab tuaj yeem tsis zoo **. Tus xeb (hlau oxide) tuaj yeem paug cov weld, uas ua rau ntxeem tau, tsis muaj zog, thiab nkig ntaub ntawv uas nquag tawg. Tsis tas li ntawd, xeb tau cuab noo noo; Thaum rhuab los ntawm vuam arc, no noo noo hloov mus rau Chav. Qhov no tuaj yeem ua rau lub weld los sib cais txaus ntshai thiab tsim cov hnab ris ntawm hydrogen, ua rau tawg lossis porosity hauv Weld. Rau qhov muaj zog thiab nyab xeeb weld, nws yog ib txwm ua tau zoo tshaj plaws kom tshem tawm tag nrho cov xeb ntawm thaj chaw yuav tsum tau welded siv ib qho li, hlau txhuam, lossis lwm txoj kev.
** 4. Dab tsi hlau yog dej? **
Tsis muaj cov khoom siv hlau uas tsis muaj zog yog "waterproof" nyob rau hauv lub siab tias nws tau muab cov dej lwg dej, raws li dej yog kua. Txawm li cas los xij, ntau cov hlau yog ib qho heev ** {{1} {resistant ** lossis ** {{{2} {{2} {{2} {{2} Kuv tsis corrode lossis tawg thaum raug dej. Tus piv txwv ua yeeb yam yog ** kub **. Kub yog qhov tseem ceeb heev thiab tsis hnov mob nrog dej lossis oxygen, uas yog vim li cas nws yeej tsis darnishes lossis xeb, txawm tias tom qab tau submerged ntev.
** 5. Cov dej muaj zog tshaj plaws - ionistant hlau? **
** Titanium ** feem ntau yog feem ntau suav tias yog ib qho ntawm cov hlau uas muaj zog tshaj plaws uas tseem muaj dej {{tsis kam. Nws muaj ib qho tshwj xeeb muaj zog - {{{3} Tshaj tawm qhov sib zog (muaj ntau dua Qhov kev sib txuam ntawm lub zog ntawm lub zog thiab kev tiv thaiv zoo heev ua rau cov kev xaiv titanium Qhov kev xaiv zoo tshaj plaws xws li cov khoom siv marine, ib feem ntawm cov khoom siv tshuaj, thiab kev cog phom. Thaum qee tus neeg tshwj xeeb stainless hlau yuav muaj zog hauv lub zog ntshiab tensile lub zog, titanium muaj qhov zoo tshaj plaws txhua-}}}}} kev sib xyaw ua ke thiab dej tsis kam.
