1.How koj tuaj yeem qhia tau yog tias ib tus hlau yog monel?
Qhia Monel feem ntau yuav tsum tau tshuaj xyuas kev tshuaj xyuas, kuaj tshuaj lom neeg, thiab qee zaum cov hau kev siv tshuab lossis analytical. Visually, monel feem ntau muaj silvery-grey tsos, zoo ib yam li stainless hlau tab sis nrog lub suab sov me me, tab sis qhov no tsis yog qhov tseeb. Tshuaj ntsuam xyuas tshuaj yuav muaj peev xwm txhim khu kev qha: Monel yog qhov muaj zog heev rau cov hlau lossis tooj liab, thaum nws yuav qhia qhov tshuaj tiv thaiv tsawg. Rau ntau qhov tseeb, x-me ntsis fluorescence (XRF) Kev tshuaj xyuas nws cov khoom tseem ceeb -}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Tsis tas li ntawd, tshuaj xyuas rau cov cim chaw tsim khoom lossis cov ntaub ntawv pov thawj (piv txwv li, ASTM cov qauv) tuaj yeem muab cov lus qhia ncaj qha yog tias muaj.
2.Qhov qeb twg yog Monel?
Monel yog hais txog ib tse neeg ntawm ob tsev neeg ntawm alloys, nrog ob peb tus tub ntxhais kawm qib sib txawv ua kom haum rau cov ntawv thov tshwj xeeb. Qhov feem ntau yog monel 400, ib qho dav dav-lub hom phiaj tag nrho nrog ~ 67% npib, ~ 30% siv rau corrosion tiv taus hauv cov tub rog marine thiab tshuaj ib puag ncig. Lwm qib ntxiv muaj monel k {5}} Monel r -405}, ib dawb machining variant ntawm 400 nrog ntxiv leej faj rau kev machinery yooj yim; thiab Monel 401, tsim los rau cov ntawv thov hluav taws xob tshwj xeeb vim nws cov tshuaj tiv thaiv sib nqus. Cov qhab nia no txhais los ntawm cov qauv xws li ASTM B127 (rau seamless yeeb) lossis ASTM B164 (rau phaj, thiab sawb).
3.Cov Monel tau welded?
Yog lawm, Monel tuaj yeem welded, tab sis nws yuav tsum tau ceev faj kom tswj tau nws corrosion tsis kam thiab cov khoom siv neeg kho tshuab. Cov Kev Vuam Vuam xws li cov roj tungsten arc vuam (gtield \/ stash vuam Cov kev txiav txim siab tseem ceeb suav nrog kev zam kev ua paug-vim tias leej txiv tau nkag siab, txhuas, thiab phosphorus lub tswv yim, uas tuaj yeem tiv thaiv cov qoob loo thaum tshav kub kub. Ua ntej Weld Tu (kom tshem tawm cov roj, oxides, lossis lwm yam kev tsis ncaj ncees) thiab cov qhab nia ntawm Weld Kev Ua Haujlwm Zoo Li Cas, tshwj xeeb hauv kev ua lag luam tseem ceeb xws li kev ua yeeb yam lossis marine engineering.
4.Huav ntxuav mancel hlau?
Kev tu MIVEL yog ncaj, raws li nws corrosion Kuj tso cai rau ntau txoj hauv kev tsis muaj kev ua kom cov khoom siv. Txog kev ntxuav tu, dej sov uas muaj xab npum me me lossis xab npum thiab daim ntaub mos muag lossis daim txhuam cev yog txaus tshem tawm cov av lossis av. Rau cov tawv nqaij tawv lossis cov tshuaj oxidation, kev daws ntawm dawb vinegar thiab dej huv (lossis ib qho me me abrasive zoo li ci dej qab zib) tuaj yeem siv, ua raws li kev yaug thiab ziab kom tiv thaiv cov dej me ntsis. Zam kev nyab xeeb cov hmoov av xws li cov roj av muaj zog hydrocalis, uas tuaj yeem etch ntawm cov npoo hlau, thiab cov ntaub thaiv cov roj av uas yuav khawb cov hlau. Rau cov ntawv thov kev lag luam, kev ntxuav ultrasonic lossis pickling nrog nitric acid (diluted) tuaj yeem siv los tshem tawm cov nplai hnyav, tab sis qhov no yuav tsum ua kom zoo kom tsis txhob dhau-etching.
5. Dab tsi yog qhov sib txawv ntawm hastelloy thiab Monel?
Hastelloy thiab Monel yog ob qho tib si nickel-raws li cov alloys tab sis txawv hauv muaj pes tsawg leeg, cov khoom, thiab cov ntawv thov. Monel yog tus nickel-tooj liab ({2}}}}}}}}}} paab ib puag ncig, nrog rau kev ua kom zoo thiab muaj zog nruab nrab. Nws ua tau zoo tshaj plaws nyob rau hauv qis rau kev kub thiab yog siv nyob rau hauv cov khoom siv marine, ntim tshuaj, thiab valve Cheebtsam.
Hastelloy, los ntawm kev sib piv, yog tsev neeg ntawm npib tsib xee-chromium alloys (nrog kev sib txawv ntawm cov molybdenum, lossis hlau) tsim rau kev ua kom mob corrosion thiab kub-kub ruaj khov. Lawv tau zoo nyob ib puag ncig zoo li cov sulfuric acid, chlorine, lossis cov mob siab rau kev siv tshuaj, nuclear reactors, thiab aerospace turbines. Cov qhab nia Hastelloy (piv txwv li, C276, B2) yog feem ntau kim dua li cov monel vim tias lawv yuav muaj zog dua rau cov tub rog ua haujlwm thiab muaj zog dua li ntawm cov tub rog thiab cov tub rog sib tw.
