Xaiv cov qib silicon hlau tsis yog tsuas yog hais txog Si%. Phau ntawv qhia no piv 553 vs 441 vs 3303 los ntawm impurity tswj, batch sib xws, thiab zoo tshaj - haum daim ntaub ntawv.
1) Vim li cas "Si%" Ib leeg tsis txaus
Thaum cov neeg yuav khoom txawv teb chaws nrhiavsilicon hlau(tseem hu uaindustrial silicon), ntau tus pib nug: "Si cov ntsiab lus yog dab tsi?" Hauv kev tsim khoom tiag tiag, tus tsav tsheb loj ntawm kev ua tau zoo yog feem ntautswj impurity-tshwj xeebFe, Al, thiab Ca-thiab ruaj khov npaum li cas cov impurities nyob ntawm ntau mus rau ntau.
Rau aluminium alloying, impurities tuaj yeem cuam tshuam qhov zoo ntawm casting thiab yaj tus cwj pwm. Rau cov tshuaj lom neeg thiab silicone- cov txheej txheem cuam tshuam, cov qib impurity tsis tu ncua thiab traceability pab txo cov txheej txheem sib txawv. Yog li es tsis txhob "siab tshaj Si=zoo tshaj," txoj hauv kev yogsib piv qib rau daim ntawv thov.
2) Kev sib piv ceev: 553 vs 441 vs 3303
Hauv qab no yog kev sib piv cov tswv yim feem ntau cov neeg yuav khoom siv thaum xaivqib silicon hlaurau kev siv tshuaj los yog tshuaj.
| Qib | Hom Kev Tso Cai | Ntsiab impurity tsom | Cov ntawv thov siv | Daim Ntawv Pom Zoo / Loj |
|---|---|---|---|---|
| 553 | Tus nqi- zoo, siv dav | Balanced impurities (kev tswj dav dav) | Aluminium casting, dav hlau metallurgy | Cov pob10-50 hli / 50-100 hli |
| 441 | purity siab tshaj 553 | Lower Fe/Al/Ca vs 553 | Aluminium alloying, impurity{0}} ua haujlwm rhiab heev | Granules3-10 hli, 10-50 hli |
| 3303 | Tshuaj-kev xaiv xaiv | Xav paub ntau ntxiv rau Ca stability | Siv tshuaj silicon, silicone saw siv | Lumps 10-50mm / 50-100mm |
Lus Cim: Cov tshuaj lom neeg yog nyob ntawm tus qauv tsim khoom. Ib txwm paub meejCOAthiab daim ntawv cog lus specs rau Fe/Al/Ca txwv.
3) Yuav xaiv li cas los ntawm Daim Ntawv Thov
A. Aluminium casting / aluminium alloying
Yog tias koj lub hom phiaj yog ruaj khov alloying kev ua tau zoo thiab kwv yees tawm los, pib nrog:
553rau kev siv cov cuab yeej siv thaum tswj tus nqi tseem ceeb heev
441thaum koj xav tau nruj impurity txwv los yog ntau ruaj khov batch kev ua tau zoo
Yog tias koj cov txheej txheem siv cov khoom noj tsis tu ncua lossis koj xav tau kom yaj sai dua, xav txoggranuleslos yog ib tug nqaim loj ntau yam.
B. Tshuaj / silicone-txog kev siv
Rau cov txheej txheem tshuaj, qhov sib xws tseem ceeb npaum li qhov muaj nuj nqis nominal. Cov neeg yuav khoom feem ntau nyiam3303(los yog cov tshuaj zoo sib xws-cov qhab nia taw qhia) vim tias lawv them nyiaj tshwj xeeb rau impurity stability-tshwj xeeb tshaj yog Ca- thiab batch traceability.
C. Cov ntaub ntawv siv sib xyaw lossis tsis paub meej
Yog tias koj tsis paub meej, nug koj tus txheej txheem engineer uas impurity yog qhov rhiab tshaj plaws:
YogFerhiab heev → txav mus rau qib purity siab dua
YogCayog qhov txwv tsis pub dhau → paub meej tias tshuaj lom neeg -qhia qib kev ruaj ntseg thiab qauv qauv
Yog hais tias koj qhov teeb meem yog "melt fluctuation" → tsom raukev faib tawm lojthiab txoj kev pub mis, tsis yog qib
4) Daim ntawv txheeb xyuas kev yuav khoom (Nug dab tsi ua ntej koj yuav)
Siv daim ntawv txheeb xyuas no kom txo tau txoj kev pheej hmoo thaum importing silicon hlau:
COA rau ntau(tsis yog daim ntawv pov thawj generic)
Batch-rau-batch rangerau Fe/Al/Ca (thov kom muaj kev ruaj ntseg keeb kwm yog tias ua tau)
Sizing cov ntsiab lus: hom phiaj ntau, oversize/undersize kam rau ua, tshuaj ntsuam txoj kev
Ntim: 1MT lub hnab loj, 25kg / 50kg hnab, sab hauv liner, tswj kev ya raws
Kev xaiv tshuaj ntsuam xyuas: thib peb-kev soj ntsuam tog, thauj cov duab, kaw lub thawv npaj
Traceability: ntau tus lej ntawm lub hnab + cov ntawv ntim khoom sib piv COA
5) Cov lus nug uas nquag nug
Q1: Puas yog 441 ib txwm zoo dua 553?
Tsis tas li . 441 feem ntau yog xaiv rau cov kev cai nruj dua impurity, tab sis 553 tuaj yeem yog tus nqi zoo tshaj - kev xaiv ua tau zoo rau cov txheej txheem kev ua haujlwm.
Q2: Kuv puas tuaj yeem siv 553 rau kev siv tshuaj?
Qee cov neeg siv khoom tuaj yeem, tab sis cov txheej txheem tshuaj lom neeg feem ntau nkag siab rau impurity stability. Yog tias Ca/Al tswj qhov teeb meem, paub meej cov specs kom zoo thiab xav txog cov tshuaj lom neeg -cov qhab nia zoo li 3303.
Q3: Qhov loj npaum li cas yog qhov zoo tshaj plaws rau aluminium casting?
Muaj ntau lub tsev tsim khoom siv10-50 hlikom ceev melting thiab zoo sib tov.50-100 hlituaj yeem tsim nyog rau kev pub mis qeeb thiab txo qhov raug.
Q4: Lumps lossis granules-Kuv yuav xaiv li cas?
Granules feem ntau yaj sai dua thiab faib ntau qhov sib npaug; lumps tuaj yeem yooj yim rau kev tswj xyuas, kev noj qeeb qeeb. Xaiv raws li koj lub qhov cub thiab txoj kev pub mis.
Q5: Cov ntaub ntawv dab tsi kuv yuav xav tau nrog kev xa khoom?
COA, packing list, invoice, bill of lading, thiab loading photos are common. Thib peb-kev tshuaj xyuas tog neeg tuaj yeem npaj tau yog tias xav tau.
