Thaum cov flake graphite rub tawm ntawm cov hlau, cov graphite zaj duab xis yog tsim rau saum npoo ntawm cov hlau thiab cov flake graphite, thiab nws cov thickness thiab degree ntawm kev taw qhia ncav cuag ib qho nqi, uas yog, flake graphite hnav sai sai thaum pib, thiab tom qab ntawd poob rau tus nqi tas li. Cov hlau huv graphite txhuam qhov chaw muaj kev taw qhia zoo dua, me me siv lead ua zaj duab xis thickness thiab adhesion loj dua. Qhov kev sib txhuam no tuaj yeem ua kom ntseeg tau tias cov ntaub ntawv hnav thiab kev sib txhuam me me kom txog thaum kawg ntawm kev sib txhuam. Furuite graphite editor hauv qab no txheeb xyuas qhov hnav tsis kam ntawm flake graphite:
Flake graphite muaj cov thermal conductivity siab, uas yuav pab kom hloov cov cua sov sai sai ntawm qhov chaw sib txhuam, kom qhov kub thiab txias hauv cov khoom thiab nws qhov chaw sib txhuam tuaj yeem sib npaug. Yog tias lub siab tseem nce ntxiv, cov yeeb yaj kiab graphite yuav raug puas ntsoog, thiab tus nqi hnav thiab kev sib txhuam coefficient kuj yuav nce sai. Rau qhov sib txawv ntawm graphite hlau txhuam qhov chaw, nyob rau hauv txhua rooj plaub, qhov siab dua qhov tso cai, qhov zoo dua qhov kev taw qhia ntawm graphite zaj duab xis tsim rau ntawm qhov chaw sib txhuam. Hauv nruab nrab huab cua nrog qhov kub ntawm 300 ~ 400 degrees, qee zaum kev sib txhuam coefficient nce vim muaj zog oxidation ntawm flake graphite.
Kev xyaum tau pom tias flake graphite yog qhov tshwj xeeb tshaj yog muaj txiaj ntsig hauv nruab nrab lossis txo cov xov xwm nrog qhov kub ntawm 300-1000 degrees. Cov khoom siv graphite hnav-tiv taus impregnated nrog hlau los yog cob yog tsim rau kev ua hauj lwm nyob rau hauv ib tug roj nruab nrab los yog ib tug kua nruab nrab ntawm cov av noo ntawm 100%, tab sis nws siv kub ntau yam yog txwv los ntawm tshav kub tsis kam ntawm resin thiab melting point ntawm lub hlau.
