Thaum cov flake graphite txhuam rau ntawm cov hlau, ib zaj duab xis graphite raug tsim rau ntawm qhov chaw ntawm cov hlau thiab cov flake graphite, thiab nws cov tuab thiab qib kev taw qhia ncav cuag qee qhov nqi, uas yog, cov flake graphite hnav sai sai thaum pib, thiab tom qab ntawd poob rau qhov nqi tas li. Cov hlau huv graphite txhuam nto muaj kev taw qhia zoo dua, cov zaj duab xis siv lead ua me dua, thiab lo rau ntau dua. Qhov kev sib txhuam nto no tuaj yeem ua kom ntseeg tau tias qhov hnav thiab cov ntaub ntawv sib txhuam me me kom txog thaum kawg ntawm kev sib txhuam. Tus kws kho graphite FRT hauv qab no tshuaj xyuas cov yam ntxwv tiv thaiv kev hnav ntawm cov flake graphite:
Flake graphite muaj cov thermal conductivity siab, uas pab hloov cua sov sai sai los ntawm qhov chaw sib txhuam, yog li qhov kub hauv cov khoom siv thiab nws qhov chaw sib txhuam tuaj yeem sib npaug. Yog tias qhov siab txuas ntxiv nce, zaj duab xis graphite uas taw qhia yuav raug puas tsuaj loj heev, thiab qhov hnav thiab coefficient sib txhuam kuj tseem yuav nce sai. Rau cov hlau graphite sib txawv sib txhuam nto, hauv txhua qhov xwm txheej, qhov siab dua qhov tso cai siab dua, qhov zoo dua qhov kev taw qhia ntawm zaj duab xis graphite tsim rau ntawm qhov chaw sib txhuam. Hauv huab cua nruab nrab nrog qhov kub ntawm 300 ~ 400 degrees, qee zaum qhov coefficient sib txhuam nce vim yog qhov muaj zog oxidation ntawm flake graphite.
Kev xyaum tau qhia tias cov flake graphite muaj txiaj ntsig zoo rau hauv cov khoom siv nruab nrab lossis txo qis nrog qhov kub ntawm 300-1000 degrees. Cov khoom siv graphite hnav-resistant impregnated nrog hlau lossis resin yog tsim rau kev ua haujlwm hauv cov roj lossis cov kua nruab nrab nrog cov av noo ntawm 100%, tab sis nws qhov kub thiab txias siv yog txwv los ntawm kev tiv thaiv cua sov ntawm cov resin thiab qhov chaw yaj ntawm cov hlau.
