Cov yam ntxwv ntawm cov graphite expandable tom qab cua sov rau hauv graphite expandable yog dab tsi?

Cov yam ntxwv ntawm kev nthuav dav ntawmDaim ntawv graphite nthuav davtxawv ntawm lwm cov neeg sawv cev nthuav dav. Thaum cua sov mus rau qee qhov kub, cov graphite nthuav dav pib nthuav dav vim yog qhov kev lwj ntawm cov tshuaj uas nqus tau hauv cov interlayer lattice, uas hu ua qhov kub nthuav dav pib. Nws nthuav dav tag nrho ntawm 1000 ℃ thiab ncav cuag qhov ntim siab tshaj plaws. Qhov ntim nthuav dav tuaj yeem ncav cuag ntau dua 200 npaug ntawm tus nqi pib. Cov graphite nthuav dav hu ua graphite nthuav dav lossis graphite worm, uas hloov pauv ntawm cov duab flake qub mus rau cov duab kab mob nrog qhov ceev tsawg, tsim cov txheej rwb thaiv tsev zoo heev. Cov graphite nthuav dav tsis yog tsuas yog qhov chaw carbon hauv lub kaw lus nthuav dav, tab sis kuj yog txheej rwb thaiv tsev. Nws tuaj yeem ua tau zoorwb thaiv cua sovHauv hluav taws, nws muaj cov yam ntxwv ntawm kev tso tawm cua sov tsawg, kev poob me me thiab cov pa roj tsawg dua.

Cov yam ntxwv ntawm cov graphite expandable tom qab cua sov rau hauv graphite expandable yog dab tsi?

Cov yam ntxwv ntawm cov graphite nthuav dav

① Muaj zog tiv taus siab,kev hloov pauv tau yooj yim, plasticity thiab tus kheej lubrication;

② Muaj zog tiv taus kub siab, qis,xebthiab kev tawg hluav taws xob;

③ Cov yam ntxwv av qeeg muaj zog heev;

④ Muaj zog heevkev coj hluav taws xob;

⑤Muaj zog tiv thaiv kev laus thiab kev cuam tshuam.

⑥ Nws tuaj yeem tiv taus qhov yaj thiab nkag mus ntawm ntau yam hlau;

⑦ Nws tsis muaj tshuaj lom, tsis muaj cov carcinogens thiab tsis ua rau ib puag ncig puas tsuaj.

Ntau cov lus qhia txog kev txhim kho ntawm cov graphite nthuav dav yog raws li nram no:

1. Cov graphite nthuav dav rau cov hom phiaj tshwj xeeb

Cov kev sim qhia tau hais tias cov kab graphite muaj lub luag haujlwm ntawm kev nqus cov nthwv dej electromagnetic. Cov graphite nthuav dav yuav tsum ua tau raws li cov kev cai hauv qab no: (1) qhov kub thiab txias pib qis thiab qhov ntim nthuav dav loj; (2) Cov khoom siv tshuaj lom neeg ruaj khov, khaws cia rau 5 xyoos, thiab qhov piv ntawm kev nthuav dav feem ntau tsis lwj; (3) Qhov chaw ntawm cov graphite nthuav dav yog qhov nruab nrab thiab tsis muaj xeb rau lub thawv cartridge.

2. Cov graphite nthuav dav

Cov khoom me me uas nthuav dav graphite feem ntau yog hais txog 300 mesh expandable graphite nrog qhov ntim nthuav dav ntawm 100ml / g. Cov khoom no feem ntau yog siv rau cov nplaim taws retardantcov tshuaj pleev xim, uas yog qhov xav tau heev.

3. Cov graphite nthuav dav nrog qhov kub siab pib nthuav dav

Qhov kub pib nthuav dav ntawm graphite nthuav dav nrog qhov kub pib nthuav dav siab yog 290-300 ℃, thiab qhov ntim nthuav dav yog ≥ 230ml / g. Hom graphite nthuav dav no feem ntau yog siv rau cov nplaim taws retardant ntawm engineering plastics thiab roj hmab.

4. Cov graphite hloov kho qhov chaw

Thaum siv cov graphite uas nthuav dav ua cov khoom siv hluav taws kub, nws cuam tshuam txog kev sib raug zoo ntawm graphite thiab lwm yam khoom. Vim yog qhov muaj cov mineralization siab ntawm graphite nto, nws tsis yog lipophilic lossis hydrophilic. Yog li ntawd, qhov chaw ntawm graphite yuav tsum tau hloov kho kom daws tau qhov teeb meem ntawm kev sib raug zoo ntawm graphite thiab lwm yam khoom. Nws tau raug pom zoo kom dawb qhov chaw graphite, uas yog, los npog qhov chaw graphite nrog ib zaj duab xis dawb, uas yog ib qho teeb meem nyuaj rau daws. Nws cuam tshuam txog membrane chemistry lossis qhov chaw chemistry. Lub chaw kuaj mob yuav ua tau li ntawd, thiab muaj teeb meem hauv kev lag luam. Hom graphite dawb nthuav dav no feem ntau yog siv ua txheej txheem hluav taws kub.

5. Qhov kub thiab txias pib qis thiab qhov kub thiab txias graphite nthuav dav

Hom graphite no pib nthuav dav ntawm 80-150 ℃, thiab qhov ntim nthuav dav ncav cuag 250ml / g ntawm 600 ℃. Qhov nyuaj hauv kev npaj cov graphite nthuav dav uas ua tau raws li qhov xwm txheej no yog: (1) xaiv tus neeg sawv cev sib xyaw ua ke; (2) Kev tswj hwm thiab kev paub txog cov xwm txheej ziab; (3) Kev txiav txim siab ntawm cov dej noo; (4) Kev daws teeb meem kev tiv thaiv ib puag ncig.
