Multiwall CNT hmoov

Multiwall CNT hmoov

Ntawm Shandong Tanfeng, peb kho MWCNT hmoov raws li qhov nruab nrab tunable, tsis yog cov dej khib nyiab los ntawm hauv pem teb reactor. Txoj kab uas hla, ntev, phab ntsa suav, thiab cov pa roj carbon amorphous yog txhua tus hu rau ntawm lub hom phiaj-vim tias txawm tias koj tab tom txhawb PA6 lossis tsim Li-ion anode, lub raj geometry txiav txim siab seb koj puas ntaus 0.5% kev thauj khoom lossis tau daig ntawm 2%.

Multiwall CNT hmoov

Muaj ib qho laj thawj MWCNT hmoov yog cov khoom siv hluav taws xob ua haujlwm nyob rau hauv ib nrab ntawm cov khoom sib xyaw, roj teeb electrodes, thiab ESD coatings shipping hnub no: nws tsis hais kom koj qiv nyiaj rau qhov project rau kev ua haujlwm. SWCNTs yog cov cuab yeej precision; multiwall tubes yog cov khoom siv hluav taws xob uas ua tau qhov ntsuas. Qhov kev ntes yog tias feem ntau "MWCNT hmoov" nyob rau hauv kev ua lag luam yog dhau -purified rau hauv luv luv stubs los yog hauv qab -purified nrog catalyst grit uas wrecks koj resin kho thiab corrodes rhiab interfaces.

NtawmShandong Tanfeng, peb kho MWCNT hmoov raws li qhov nruab nrab tunable, tsis yog cov dej khib nyiab los ntawm cov reactor pem teb. Txoj kab uas hla, qhov ntev, phab ntsa suav, thiab cov pa roj carbon amorphous yog txhua tus hu rau ntawm lub hom phiaj -vim tias txawm tias koj tab tom txhawb PA6 lossis tsim lub Li-ion anode, lub raj geometry txiav txim siab seb koj puas ntaus 0.5% loading lossis tau daig ntawm 2%.

Vim li cas MWCNT Powder Tseem Yeej Qhov Volume tiag

Thaum tus spec hais tias "conductive, ntxiv dag zog, thiab tsis yog $ 2,000 / kg," multiwall yog cov lus teb. Concentric graphene phab ntsa muab rau koj:

Cov khoom siv hluav taws xob loj​ ntawm 0.3–1.5 wt% loading-zoo hauv qab carbon dub's 2-5 wt% ntau.

Mechanical qaum: 10–60 GPa tensile, ~ 1 TPa modulus, yog li koj tsis yog ua xwb, koj nyob nraum stiffening.

Thermal los ntshav -tawm​ (>2000 W/m·K raws axis) uas carbon dub tsuas tsis phim.

Txheej txheem zam txim: yooj yim tawg dua SWCNTs, ua siab ntev ntawm tus qauv siab -shear thiab extruder mixing.

Kev Ncaj Ncees Kev Lag Luam - tawm ntawm Rooj

Peb tau khiav cov kev tshuaj xyuas kom txaus kom paub qhov twg txhua qhov muab tub lim tau txais nws khaws cia. Nov yog daim duab tiag tiag:

Qhov chaw qab zib yog nyob rau hauv nruab nrab: MWCNT muab rau koj 80% ntawm SWCNT network tau txais txiaj ntsig ntawm ib feem ntawm tus nqi, thiab tsis muaj cov pa roj carbon -dub qhov hnyav.

Qhov twg Tanfeng MWCNT hmoov rub nws qhov hnyav

Li-ion / Na- ion electrodes: Ntev-qib (5–20 µm) cov raj txuas txuas cov khoom siv hluav taws xob, txiav CB ntau npaum li cas, thiab tuav lub network kev ncaj ncees los ntawm kev caij tsheb kauj vab.

Engineering yas masterbatch (PP / PA / PC / ABS): luv-qib (1–2 µm) cov hlab ntsha tawg kom huv si ntawm ntxaib- ntsia hlau extruders, txiav nto resistivity rau 10⁶–10⁸ Ω/sq yam tsis tua muaj zog.

Roj hmab & log tsheb: Ntxiv kua muag kuj thiab thermal conductivity ntawm<1 phr.

EMI shielding & antistatic txheej: Ntev- qib raj tsim 3D mesh hauv epoxy/acrylic/polyurethane.

Cov khoom siv thermal interface: Axis-kev taw qhia thaum tshav kub kub thauj khoom tshaj graphite flake nyob rau hauv constrained stacks.

Shandong Tanfeng Qhov txawv (MWCNT-Specific)

Tsis zoo li SWCNTs qhov twg txhua tus sib ntaus sib tua, kev sib ntaus sib tua MWCNT yogkev sib xws thiab morphology tswj. Peb muaj qhov ntawd:

CVD morphology ntsuas phoo: Floating-catalyst txaj tuned los tuav OD nyob rau hauv nruj bands-10–30 nm, 30–60 nm, los yog 60–100 nm-thiab ntev yog luv (1–2 µm) los yog ntev (5–20 µm). Tsis muaj "sib xyaw txaj" surprise.

Purification uas tsis truncate: Peb cov kua qaub / thermal ua ntu zus strips Fe / Co / Ni rau<30 ppm while leaving tube length intact. Generic suppliers burn the ends; we don't.

Fluffy, tsis yog -bricked sau: Post-kev kho mob passivates van der Waals re-entanglement yog li lub hnab 500g thiab lub hnab ntim ob qho tib si nchuav zoo li cocoa hmoov, tsis yog graphite av nplaum.

Hauv -tsev metrology: Txhua lub nkoj xa nrog Raman ID / IG, BET SSA, TEM qhov ntev faib, thiab ICP-MS daim ntawv qhia hlau. CV ntawm cov khoom thiab ID / IG nyob<5% across campaigns.

Functionalization ntawm kev thov: Pristine, –COOH, –OH, los yog polymer-grafted qib rau dej-yug, NMP, los yog yaj- txoj kev sib xyaw.

Vim peb kuj ua cov slurry thiab masterbatch versions hauv -tsev, yog tias koj tom qab txiav txim siab qhuav dispersion yog noj koj cov paj, peb twb muaj koj cov ntaub ntawv ntiv tes.
