Cov yam ntxwv ntawm cov graphite expandable tom qab cua sov

Cov yam ntxwv ntawm kev nthuav dav ntawm cov graphite flake uas nthuav dav tau txawv ntawm lwm cov neeg sawv cev nthuav dav. Thaum cua sov rau qee qhov kub, cov graphite uas nthuav dav tau pib nthuav dav vim yog kev lwj ntawm cov tshuaj uas raug kaw hauv cov interlayer lattice, uas hu ua qhov kub nthuav dav pib. Nws nthuav dav tag nrho ntawm 1000 ℃ thiab ncav cuag nws qhov ntim siab tshaj plaws. Qhov ntim nthuav dav tuaj yeem ncav cuag ntau dua 200 npaug ntawm qhov ntim pib, thiab cov graphite nthuav dav hu ua cov graphite nthuav dav lossis graphite worm, uas hloov pauv ntawm cov duab scaly thawj mus rau cov duab worm 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 cov txheej rwb thaiv tsev, uas tuaj yeem rwb thaiv tsev cua sov tau zoo. Nws muaj cov yam ntxwv ntawm kev tso tawm cua sov tsawg, kev poob me me thiab cov pa luam yeeb tsawg dua hauv hluav taws. Yog li cov yam ntxwv ntawm cov graphite nthuav dav tom qab nws raug cua sov rau hauv cov graphite nthuav dav yog dab tsi? Nov yog tus editor los qhia nws kom ntxaws:

1, muaj zog tiv taus siab, yooj ywm, plasticity thiab tus kheej lubrication;

2. Kev tiv thaiv kub thiab txias heev, kev tiv thaiv corrosion thiab kev tiv thaiv hluav taws xob;

3. Cov yam ntxwv ntawm av qeeg muaj zog;

4. Kev coj ua hluav taws xob siab heev;

5. Muaj zog tiv thaiv kev laus thiab kev cuam tshuam cov yam ntxwv;

6. Nws tuaj yeem tiv taus qhov yaj thiab infiltration ntawm ntau yam hlau;

7. Tsis muaj tshuaj lom, tsis muaj carcinogen, thiab tsis muaj kev puas tsuaj rau ib puag ncig.

Qhov kev nthuav dav ntawm graphite nthuav dav tuaj yeem txo qhov thermal conductivity ntawm cov khoom thiab ua tiav cov nyhuv retardant nplaim taws. Yog tias ntxiv cov graphite nthuav dav ncaj qha, cov qauv txheej carbon uas tsim tom qab combustion yeej tsis tuab. Yog li ntawd, hauv kev tsim khoom lag luam, yuav tsum ntxiv cov graphite nthuav dav, uas muaj cov nyhuv retardant nplaim taws zoo hauv cov txheej txheem ntawm kev hloov pauv mus rau hauv graphite nthuav dav thaum cua sov.
