Graphite siv lead ua yog hexagonal mesh planar txheej txheej tsim los ntawm cov ntsiab lus carbon.Kev sib txuas ntawm cov khaubncaws sab nraud povtseg yog qhov tsis muaj zog thiab qhov kev ncua deb ntawm cov khaubncaws sab nraud povtseg yog qhov loj.Nyob rau hauv cov xwm txheej tsim nyog, ntau yam tshuaj xws li acid, alkali thiab ntsev tuaj yeem muab tso rau hauv graphite txheej.Thiab ua ke nrog cov pa roj carbon atoms los tsim cov tshuaj tshiab theem-graphite intercalation compound.Thaum rhuab mus rau qhov tsim nyog qhov kub thiab txias, qhov interlayer compound tuaj yeem decompose sai thiab tsim cov pa roj ntau, uas ua rau cov graphite nthuav dav hauv axial kev taw qhia mus rau hauv cov khoom zoo li worm, uas yog, nthuav graphite.Qhov no hom ntawm unexpanded graphite intercalation compound yog expandable graphite.
Daim ntawv thov:
1. Cov khoom siv sealing: Piv nrog cov khoom siv sib khi xws li asbestos roj hmab, hloov tau yooj yim graphite npaj los ntawm nthuav graphite muaj zoo plasticity, resilience, lubrication, lub teeb yuag, hluav taws xob conductivity, tshav kub conduction, kub tsis kam, acid thiab alkali corrosion kuj, siv nyob rau hauv aerospace, machinery, electronics, nuclear zog, petrochemical, hluav taws xob fais fab, shipbuilding, smelting thiab lwm yam lag luam;
2. Kev tiv thaiv ib puag ncig thiab biomedicine: Kev nthuav dav graphite tau los ntawm kev kub siab nthuav dav muaj cov qauv pore nplua nuj, kev ua haujlwm zoo adsorption, lipophilic thiab hydrophobic, tshuaj lom neeg ruaj khov, thiab rov ua dua tshiab;
3. Cov khoom siv roj teeb muaj zog: Siv lub zog dawb hloov pauv ntawm cov tshuaj tiv thaiv interlayer ntawm expandable graphite los hloov nws mus rau hauv lub zog hluav taws xob, uas feem ntau yog siv los ua qhov tsis zoo electrode hauv lub roj teeb;
4. Nplaim-retardant thiab hluav taws-retardant cov ntaub ntawv:
a) Sealing strip: siv rau lub qhov rooj hluav taws, qhov rais hluav taws kub, thiab lwm yam.;
b) Lub hnab ntim hluav taws xob, cov khoom siv hluav taws xob tiv thaiv hluav taws xob, lub nplhaib hluav taws kub: siv los kaw cov kav dej, cables, xov hlau, roj, kav dej, thiab lwm yam.;
c) nplaim-retardant thiab anti-static xim;
d) Phab ntsa rwb thaiv tsev;
e) Foaming agent;
f) Yas nplaim retardant.
