Ib phab ntsa Carbon Nanotube Powder (SWCNT)
Yog tias koj tau sim tsim nrog ib phab ntsa carbon nanotubes, koj twb paub ob yam uas ua rau cov txheej txheem engineers tsaug zog: cov hmoov xav ya mus sai li sai tau thaum koj qhib lub hnab, thiab ib zaug nws nyob rau hauv koj cov resin, nws clumps rau hauv microscopic haystacks uas tsis muaj pes tsawg ntawm shear yuav tag nrho undo. Cov neeg muag khoom feem ntau muag koj tus lej rau ntawm daim ntawv spec -purity, txoj kab uas hla, ntev- yam tsis tau suav nrog qhov tseeb tias yog tias cov hmoov yog irreversibly entangled los yog loaded nrog catalyst residue, koj qhov percolation pib yuav ya mus lawm.
NtawmShandong Tanfeng, peb tsis kho SWCNT hmoov raws li cov khoom lag luam byproduct. Peb tsim nws los ntawm lub reactor mus, vim hais tias thaum koj ua hauj lwm ntawm 0.05% loading theem, sib xws tsis yog ib tug zoo - rau - muaj - nws yog tib yam uas ua rau koj txoj kab khiav.
Vim li cas SWCNT Powder Hloov MWCNT lossis CB?
Koj tsis hloov mus rau ib phab ntsa carbon nanotubes vim koj xav siv nyiaj ntau dua. Koj hloov vim koj tau tsoo lub qab nthab ntawm ntau yam - cov phab ntsa thiab cov pa roj carbon dub tuaj yeem ua tau. Thaum koj xav tau pob tshab, ultra- tsis tshua muaj loading, los yog ib tug conductive network uas muaj sia nyob silicon o thiab khoom-lub xeev pawg siab, SWCNTs nyob rau hauv ib pab koomtes sib txawv.
Ib txheej graphene dov rau hauv ib lub raj (1-2 nm txoj kab uas hla) muab rau koj:
Percolation pib 5-10 × qis duatshaj MWCNTs hauv polymers thiab coatings.
Hlau -qib conductivityntawm ib feem ntawm ib feem pua ntawm kev thauj khoom.
Caij nplooj ntoos hlav-zoo li hloov tauuas tsis snap nyob rau hauv particle expansion los yog dabtsi yog khoov kev nyuaj siab.
Kev sib piv ncaj ncees
Peb tau khiav txaus sab -los ntawm - sab formulations kom paub qhov twg txhua yam khoom khwv tau nws khaws cia. Nov yog qhov kev lag luam tiag tiag-tawm thaum koj txav los ntawm cov khoom siv sib xyaw ua ke rau Shandong Tanfeng SWCNT hmoov:

Qhov twg hmoov no rub nws qhov hnyav
Peb pom SWCNT hmoov teev thaum kev ua tau zoo trumps tus nqi ntshiab -ib -kilo xav:
Tom ntej no -gen roj teeb anodes/cathodes: Silicon-carbon, siab-nickel NCM, khoom- xeev- nyob qhov twg lub network conductive tau ntxhov siab.
Transparent conductive films: Kov vaj huam sib luag, hloov tau cov lus qhia, qhov twg ITO nkig dhau lawm thiab MWCNTs pom dhau lawm.
ESD{0}}polymers nyab xeeb: PC, PET, PA zaj duab xis thiab vaj tse xav tau 10⁶–10⁹ Ω/sq yam tsis muaj qhov pom tseeb lossis gloss.
EMI shielding composites: Lub teeb yuag, tsis yog -hlau lwm txoj hauv kev rau aerospace thiab siab - zaus hluav taws xob.
Conductive inks & pastes: Cov khoom siv hluav taws xob luam tawm qhov kev txuas ntxiv tseem ceeb ntawm ultra- zaj duab xis tuab.
Qhov zoo ntawm Shandong Tanfeng
Ntau tus neeg muag khoom yuav arc- tso tawm lossis cov hmoov CVD generic, rov ntim nws, thiab vam tias koj cov kauj ruam dispersion kho qhov seem. Peb tsis ua.Shandong Tanfengkhiav cov khoom lag luam ntab-catalyst CVD kab uas peb tswj cov catalyst formulation, roj theem, thiab nyob rau lub sij hawm- yog li cov hmoov koj tau txais yog tsim rau dispersibility, tsis yog siab purity ntawm daim ntawv.
Qhov ntawd txhais li cas ntawm koj hauv pem teb:
Kev faib tawm me me (1-2 nm)nrog tunable ntev (5-30 µm), yog li koj cov ntaub ntawv network tau kwv yees ntawm tib qhov chaw thau khoom txhua pawg.
