Hauv cov khoom siv tshiab R & D thiab kev tsim khoom loj, cov pa roj carbon nanotubes tau txais txiaj ntsig zoo rau lawv cov hluav taws xob zoo, thermal, thiab cov khoom siv kho tshuab. Txawm li cas los xij, ntau tus kws tshaj lij thiab cov kws tshaj lij yuav ntsib qhov mob thaum xaiv: yuav ua li cas xaiv carbon nanotube purity? Qhov txawv ntawm 95% / 99% / 99.9% yog dab tsi? Purity tsis tsuas yog cuam tshuam rau kev ua tau zoo ntawm cov khoom kawg tab sis kuj ncaj qha txiav txim siab txog cov khoom siv nyiaj txiag. Kev xaiv qis heev cuam tshuam rau cov qoob loo; xaiv siab dhau yuav ua rau kev ua haujlwm tsis zoo. Niaj hnub no, peb yuav tshawb nrhiav cov laj thawj hauv qab no thiab pab koj qhia meej txog kev xaiv lub tswv yim rau siab -purity carbon nanotubes.
Vim li cas Purity yog Lifeline rau Kev Xaiv Carbon Nanotube?
Qhov siab dua qhov purity, qhov qis dua qhov seem hlau catalysts thiab amorphous carbon impurities nyob rau hauv cov pa roj carbon nanotubes, uas ncaj qha txiav txim siab lawv electrochemical stability thiab mechanical reinforcement los nyob rau hauv downstream daim ntaub ntawv. Cov impurities tsis tsuas yog tsis tuaj yeem txhawb nqa tab sis kuj dhau los ua "invisible killers" uas rhuav tshem cov kab ke.
Raws li kev taw qhia ntawm tus txheej txheem thoob ntiaj teb ISO / TS 11308, yog cov hlau catalyst impurities xws li hlau, cobalt, thiab npib tsib xee hauv cov pa roj carbon nanotubes tshaj ib qho kev faib ua feem, lawv tuaj yeem yooj yim ua rau muaj kev cuam tshuam tsis zoo hauv cov roj teeb hluav taws xob tshiab, ua rau lub roj teeb muaj peev xwm lwj lossis txawm tias thermal runaway. Nyob rau tib lub sijhawm, lub xub ntiag ntawm amorphous carbon blocks electron thauj network, txo cov macroscopic conductivity ntawm cov khoom. Yog li, kom meej meej txhais cov ciam teb ntawm 95%, 99%, thiab 99.9% yog qhov yuav tsum tau ua ua ntej rau kev tsim cov khoom tsim nyog.
Core Differences thiab Quantitative Comparison ntawm 95%, 99%, thiab 99.9% Carbon Nanotubes
Qhov tseem ceeb sib txawv ntawm peb qhov lus dag nyob rau hauv cov ntsiab lus seem impurity thiab cov xwm txheej tsim nyog muaj. Txhua lub sij hawm purity nce los ntawm qhov kev txiav txim ntawm qhov loj, qhov nyuaj ntawm cov txheej txheem purification thiab tus nqi nce exponentially.
Txhawm rau kom paub ntau ntxiv txog qhov sib txawv, peb tau sau cov lus sib piv hauv qab no raws li TGA (Thermogravimetric Analysis) thiab ICP-OES (Inductively Coupled Plasma Optical Emission Spectroscopy):
| Purity Level | Hlau impurity Residue | Cov ntsiab lus ntawm Amorphous Carbon | Daim ntawv thov Scenario Ib txwm siv | Tus nqi tsim khoom Index | Suitability Suitability Summary |
|---|---|---|---|---|---|
| 95% | Tsawg dua lossis sib npaug li 3.5% | Tsawg dua lossis sib npaug li 1.5% | General yas reinforcement, anti- txheej txheej zoo li qub, hloov kho roj hmab zoo tib yam | Tsawg (1.0x) | Thawj qhov kev xaiv rau tus nqi -effectiveness, siab kam rau siab rau impurities |
| 99% | Tsawg dua lossis sib npaug li 0.5% | Tsawg dua lossis sib npaug li 0.5% | Lub hwj chim lithium roj teeb conductive additives, siab -kev ua tau zoo thermally conductive silicone, tshwj xeeb txheej | Nruab nrab (2.5x) | Industrial mainstream, ntsuas kev ua tau zoo thiab tus nqi |
| 99.9% | Tsawg dua lossis sib npaug li 0.05% | Tsawg dua lossis sib npaug li 0.05% | Semiconductor ntim, aerospace-qib resins, siab -kawg conductive films | Siab (5.0x+) | Kev ua tau zoo kawg nkaus, mob siab rau siab - thaj chaw muaj tseeb |
Yuav Ua Li Cas Xaiv Carbon Nanotube Purity? Tswv yim Scenario Xaiv thiab Kev Qhia Qhia
Lub hauv paus ntsiab lus ntawm kev xaiv yog "muab raws li kev xav tau." Kev lag luam roj teeb saib ntawm electrochemical stability, kev lag luam plastics saib ntawm dispersibility thiab nqi, thiab kev lag luam hluav taws xob saib ntawm qhov kawg purity. Tsis txhob dig muag mus nrhiav qhov purity siab tshaj.
1. Fais fab Lithium roj teeb thiab lub zog cia chaw: 99% yog thawj qhov kev xaiv
Nyob rau hauv lithium roj teeb conductive additive daim ntaub ntawv, hlau impurities yog tuag taus. Cov hlau ions siab dua hauv 95% carbon nanotubes tuaj yeem rhuav tshem SEI zaj duab xis thaum lub sij hawm them nqi - paug tawm . 99% purity carbon nanotubes tuaj yeem tsim tau ntev -cov kab hluav taws xob sib txuas thaum ua kom tsis huv hauv qhov chaw nyab xeeb. Qhov no yog tam sim no cov khoom lag luam zoo tshaj plaws rau cov tuam txhab roj teeb ua lag luam.
2. Polymer Composites thiab Plastic Modification: 95% yog tus huab tais ntawm tus nqi -effectiveness
Yog tias koj tsuas yog yuav tsum tau ntxiv cov khoom tiv thaiv zoo li qub lossis cov khoom siv kho tshuab rau cov khoom siv hluav taws xob zoo tib yam (xws li PE, PP), 95% purity yog tag nrho. Nyob rau hauv daim teb no, dispersibility ntawm carbon nanotubes feem ntau tseem ceeb tshaj purity. Xaiv 95% purity nrog cov txheej txheem kev hloov kho saum npoo zoo tuaj yeem ua tiav qhov kev xav tau ntim ntawm tus nqi qis tshaj, tsis tas yuav nkim nyiaj ntawm 99%.
3. Txiav -Edge Electronics thiab Semiconductor Materials: 99.9% yog qhov yuav tsum tau ua
Nyob rau hauv cov xwm txheej tsis tshua muaj siab rau cov kab hlau, xws li cov khoom ntim ntim thiab cov khoom siv hluav taws xob tiv thaiv hluav taws xob, txawm tias 0.5% hlau residues tuaj yeem ua rau lub cev tsis zoo los yog teeb liab cuam tshuam . 99.9% qib siab- purity carbon nanotubes yuav tsum tau siv los xyuas kom meej meej purity ntawm lub system.
