Dab tsi Electrolytic Manganese Flakes Yog
Electrolytic manganese hlau flakes, feem ntau luv rau EMM, yog tsim los ntawm electrolysis ntawm manganese sulfate tov thiab xa raws li nyias, brittle flakes nrog ib tug manganese ntsiab lus ntawm 99.7 feem pua los yog siab dua nyob rau hauv cov metallurgical qib. Daim ntawv flake dissolves sai thiab sib npaug thaum nws ntxiv rau molten aluminium, uas yog vim li cas kev lag luam txhuas yog cov neeg siv khoom loj tshaj plaws. Cov qib purity qis dua mus rau steelmaking thiab rau zus tau tej cov manganese tebchaw.
Qhov tseem ceeb ntawm kev siv qib siab purity yog raws li kev sib xyaw ua ke hauv cov khoom siv thiab cam khwb cia aluminium alloys, qhov twg manganese ntxiv nyob rau hauv thaj tsam li ntawm 0.5 feem pua rau 1.5 feem pua ntawm qhov hnyav nyob ntawm tsev neeg hlau. Hlau thiab sulfur impurities degrade hluav taws xob conductivity thiab nto tiav, yog li EMM teev rau txhuas alloying nqa nruj txwv ntawm cov ntsiab lus.
Yuav ua li cas Manganese Hloov Aluminium Alloys
Manganese cov ntaub ntawv zoo intermetallic dispersoids xws li Al6Mn hauv aluminium matrix. Cov khoom no pin cov ciam teb thiab retard recrystallization, yog li lawv tsa tensile lub zog thiab hardness yam tsis tau poob ntawm ductility uas los ntawm tshaj - hardening lub matrix.
Plaub qhov teebmeem tseem ceeb hauv kev xyaum. Lub zog: cov dispersoids nce yield thiab tensile lub zog thaum lub alloy nyob twj ywm ua hauj lwm. Corrosion resistance: manganese stabilizes nto oxide thiab txhim kho kev tiv thaiv rau pitting nyob rau hauv marine thiab me acidic ib puag ncig, uas yog ib qho tseem ceeb rau tshuaj cia tank thiab shipbuilding. Thermal stability: grain ciam pinning txwv tsis muaj zog ntawm qhov kub thiab txias, txhawb kev siv nyob rau hauv tshav kub exchangers thiab cav Cheebtsam. Kev ua haujlwm tau zoo: cov qauv ua kom zoo dua qub txo qhov kev pheej hmoo ntawm kev tawg thaum dov thiab extrusion.
Ntsiab Aluminium Alloys siv EMM
| Alloy | Manganese cov ntsiab lus | Tej daim ntawv thov |
|---|---|---|
| 3003 | txog 1.2 feem pua | Cov kaus poom dej haus, daim ntawv vov tsev, HVAC panels |
| 3004 | txog 1.3 feem pua | Lub cev muaj peev xwm, automotive roj tank, ntim |
| 5083 thiab lwm yam 5000 series | manganese nrog magnesium | Nkoj hulls, marine structures, welded siab hlab ntsha |
| A380 thiab lwm yam casting alloys | txog li 0.5 feem pua | Tuag cam khwb cia vaj tse, txo kub tearing, zoo fluidity |
Nyob rau hauv 5000 series, manganese ua hauj lwm nrog magnesium los txhim kho weldability thiab tsis kam mus rau kev nyuaj siab corrosion cracking, uas yog vim li cas marine qib phaj rau hulls thiab offshore qauv cia siab rau kev sib xyaw ua ke. Nyob rau hauv casting alloys cov manganese ntxiv txo kub tearing thiab txhim kho fluidity thaum tuag casting.
Qhov zoo dua lwm qhov chaw Manganese
Siab purity. Cov ntsiab lus manganese ntawm 99.7 feem pua lossis siab dua khaws cov hlau, sulfur thiab phosphorus nyob rau theem qis, tiv thaiv conductivity thiab nto zoo.
Uniform particle loj. Txawm tias me me flakes yaj tas li, yog li kev txheeb xyuas muaj pes tsawg leeg ntawm txhua lub tshav kub sib tw rau lub hom phiaj yam tsis muaj manganese nplua nuj zones.
Tus nqi efficiency. Ntxiv manganese txo cov nqi ntawm cov khoom siv kim dua xws li tooj liab lossis npib tsib xee uas xav tau kom ncav cuag qib siab.
Kev huv huv. Tsawg roj thiab cov ntsiab lus slag tsawg txwv porosity thiab suav nrog khaws hauv cov yaj.
Kev siv hauv ntim, thauj thiab lub zog
Lub teeb yuag hauv kev tsim tsheb yog tus tsav tsheb muaj zog, vim tias manganese ntxiv dag zog rau aluminium hloov cov khoom siv hlau thiab txiav cov tsheb loj. Recyclable aluminium ntim, suav nrog cov manganese bearing tuaj yeem ua rau lub cev alloys, tseem loj hlob hauv cov khoom noj thiab dej haus. Lub tshuab roj teeb kuj tseem qhib qhov kev thov tshiab, nrog manganese aluminium alloys tshawb nrhiav rau lub teeb yuag roj teeb vaj tsev thiab cov khoom siv hauv tsheb hluav taws xob, qhov twg tib qho kev txhawb zog thiab thermal stability siv tau.
Aluminium ntawv thiab phaj tsim los ntawm cov alloys no feem ntau tau ntawv pov thawj rau ASTM B209, uas npog aluminium thiab aluminium alloy ntawv thiab phaj thiab kho qhov muaj pes tsawg leeg thiab cov cuab yeej cuab tam qhov rais uas muaj manganese ntxiv yuav tsum txaus siab.
Specification thiab tuav ua raws tib lub logic. Electrolytic manganese flakes tau muab tso rau hauv cov hnab ntim khoom lossis cov nruas nrog daim ntawv pov thawj tsom xam suav nrog manganese, hlau, sulfur, phosphorus, selenium thiab silicon. Cov flakes yog hygroscopic nyob rau hauv cov huab cua ntub, yog li cia yuav tsum qhuav thiab lub hnab yuav tsum tau muab rov qab tom qab siv ib nrab. Ntxiv yog feem ntau ua rau yaj hauv lub cub tawg es tsis yog nyob rau hauv lub qhov cub tuav, kom dispersion thiab dissolution tiav ua ntej casting.
Cov lus nug nquag
Q: Dab tsi yog qhov purity ntawm electrolytic manganese flakes?
Metallurgical qib EMM feem ntau yog teev nyob rau ntawm 99.7 feem pua manganese lossis siab dua, nrog nruj tswj cov hlau, sulfur thiab phosphorus kom cov khoom txhuas tsis degraded.
Q: Ntau npaum li cas manganese ntxiv rau aluminium?
