Q1: EMM flakes COA yog dab tsi?
A: COA (Certificate of Analysis) yog ib daim ntawv qhia rau ntau yamelectrolytic manganese hlau flakes (EMM flakes). Nws tshaj tawm cov txiaj ntsig tshuaj ntsuam xyuas thiab cov cim xa khoom tseem ceeb kom tus neeg yuav khoom tuaj yeem txheeb xyuas cov khoom thauj raws li qhov pom zoo.
Q2: Dab tsi yog thawj cov khoom uas kuv yuav tsum tau kuaj xyuas ntawm COA?
A: Pib nrog ntu "tus kheej" kom ntseeg tau tias COA phim koj cov khoom xa tuaj:
- Khoom npeElectrolytic Manganese Hlau Flakes / EMM Flakes
- Qib / purity: Piv txwv li, Mn 99.70% min lossis 99.90% min
- Lot/Batch Number: yuav tsum phim lub hnab / ntim cov npe yog tias yuav tsum tau taug qab ntau
- Net nyhavthiabpob suav(yog tias pom)
- Hnub tsim khoomlos yogxeem hnub(pab tau rau traceability)
Q3: Cov txiaj ntsig tshuaj twg yog qhov "yuav tsum- kuaj" cov khoom?
A: Cov neeg yuav khoom feem ntau kuaj:
- Mn (%): yuav tsum tau ntsib lossis tshaj qhov tsawg kawg nkaus purity hauv koj PO (piv txwv li, Ntau dua lossis sib npaug li 99.70%)
- Fe (hlau): tej yam tseem ceeb impurity cuam tshuam rau alloy huv si
- C (carbon)thiabS (sulfur): tseem ceeb rau kev tswj chemistry
- P (phosphorus): feem ntau txwv rau qhov sib xws
- Nyob ntawm koj qhov kev siv kawg, koj tuaj yeem xav tau cov txiaj ntsig rau:Si, Ni, Cu, Pb, As(thiab lwm yam kab kawm).
Q4: Kuv yuav piv cov txiaj ntsig COA li cas nrog kuv qhov tshwj xeeb?
A: Siv daim ntawv xeem dhau los/ua tsis tau yooj yim:
- Paub meejMn yog siab tshaj koj yam tsawg kawg nkauskev xav tau.
- Paub meej tias txhua impurity yoghauv qab koj qhov siab tshaj plawstxwv (Fe, C, S, P, thiab lwm yam kev xaiv).
- Tshawb xyuas seb COA qhia antau, "max," lossis ib tus nqi-koj daim ntawv cog lus yuav tsum txhais qhov uas yuav tsum tau ua.
- Yog koj PO xav taunruab nrab ntawm cov qauvlos yogcomposite sampling, xyuas kom tseeb tias COA sampling txoj kev sib tw.
Q5: Yuav ua li cas yog tias COA qhia qhov "tseem ceeb" tsis muaj kev txwv?
A: "Tswj" qhov tseem ceeb tsis zoo ib yam li kev cog lus txwv. Rau kev txiav txim nruj, koj PO yuav tsum hais tias:
- Covtso cai siab tshaj plawsrau txhua impurity
- Seb cov txiaj ntsig yog rau antau composite qauv
- Yuav ua li cas yog tias cov txiaj ntsig tawm ntawm qhov tshwj xeeb (re- txoj cai xeem, thib peb- kev tshuaj ntsuam xyuas, kev tuav pov hwm)
Q6: Puas yog COA yuav suav nrog qhov loj me, tuab, lossis nplua piv rau flakes?
A: Qee zaum, tab sis tsis tas li. Yog tias qhov loj / nplua yog qhov tseem ceeb rau koj cov txheej txheem, thov kom tus neeg muag khoom muab:
- Flake loj / thickness phiaj(los yog daim ntawv qhia txog qhov loj me)
- Max nplua txhais(piv txwv li, "hauv qab X mm Tsawg dua lossis sib npaug rau Y%")
- Covxeem txoj kevsiv (sieve xeem standard thiab sampling txoj cai)
Yog tias COA tsis suav nrog cov ntaub ntawv lub cev, koj tuaj yeem xav tau caisdaim ntawv ntsuam xyuas lojlos yog pom zoo rau kev tau txais kev kuaj xyuas.
Q7: Cov nqe lus tshuaj xyuas thiab kev coj ua dab tsi yuav tsum cov neeg yuav khoom txhais ua ntej?
A: Txhawm rau zam kev tsis sib haum xeeb, qhia meej:
- Qhov twg ua piv txwv tshwm sim (ua ntej xa khoom xa tuaj, ntawm qhov chaw nres nkoj, lossis tom qab tuaj txog)
- Txoj kev coj mus kuaj (lub hnab random, tus naj npawb ntawm increments, composite qauv cai)
- Lab txoj kev (lub chaw tsim khoom, chaw kuaj neeg yuav khoom, lossis thib peb- tog)
Kev daws teeb meem (re-sampling, referee lab, tso cai kam rau ua yog tias muaj)
Q8: Dab tsi yog COA liab chij rau EMM flakes?
A: Saib rau:
- Tsis meejntau/batch identification
- ploj lawmMntshwm sim los yog ploj lawm tseem ceeb impurities
- Cov txiaj ntsig tau teev tseg raws li "tus qauv" uas tsis muaj kev cog lus siab tshaj plaws
- COA hnub tim deb ntawm kev tsim khoom / khoom xa tuaj uas tsis muaj traceability
- Tsis muaj daim ntawv kos npe/stamp lossis tus neeg muab ntawv pov thawj tsis meej
- COA tshwm sim uas tsis sib haum nrog qhov pom zoo spec lossis keeb kwm yav dhau los
FAQ
Q1: Puas yog COA txaus los lav qhov zoo?
A: Nws yog ib qho tseem ceeb pov thawj cov cuab yeej, tab sis cov neeg yuav khoom yuav tsum tau pom zoo rau cov qauv / kuaj cov cai thiab tuaj yeem ua qhov kev tshuaj xyuas tuaj rau kev txiav txim tseem ceeb.
Q2: Dab tsi yog tus lej tseem ceeb ntawm EMM flakes COA?
A: Mn (%) rau purity, ua raws li cov impurities tseem ceeb xws li Fe, C, S, P raws li koj daim ntawv thov.
Q3: Kuv puas tuaj yeem tsis lees txais cov khoom thauj yog tias kuv qhov kuaj pom txawv ntawm COA?
A: Qhov no nyob ntawm qhov kev pom zoo soj ntsuam thiab kev tsis sib haum xeeb. Txhais cov txheej txheem rov- kuaj lossis tus neeg saib xyuas kev kuaj hauv PO los daws qhov sib txawv.
