Cov yam ntxwv tseem ceeb ntawm cov ntaub ntawv graphite nthuav dav

Cov khoom siv graphite uas yoog tau yog cov khoom tsis yog fibrous, thiab nws raug pwm ua cov khoom ntim tom qab ua rau hauv phaj. Pob zeb yoog tau, tseem hu ua graphite nthuav dav, tshem tawm cov khoom tsis huv ntawm cov flake graphite ntuj. Thiab tom qab ntawd kho nrog cov kua qaub oxidizing muaj zog los ua graphite oxide. Graphite oxide raug rhuav tshem los ntawm cua sov kom tso cov pa roj carbon dioxide, uas nthuav dav sai thiab dhau los ua xoob, mos thiab tawv.
Kev sib deev nthuav dav graphite. Cov Furuite Graphite hauv qab no Xiaobian qhia txog cov yam ntxwv ntawm kev nthuav dav graphite:

1. Tiv taus cua sov thiab txias zoo heev.
Txij li qhov kub tsawg heev ntawm -270 degrees mus rau qhov kub siab ntawm 3650 degrees (hauv cov roj tsis-oxidizing), cov khoom siv lub cev ntawm cov graphite nthuav dav tsis hloov pauv ntau, thiab nws kuj tseem siv tau rau li 600 degrees hauv huab cua.
2. Nws muaj lubricity zoo.
Ib yam li cov graphite ntuj, cov graphite nthuav dav yooj yim rau kev txav mus los ntawm cov khaubncaws sab nraud povtseg nyob rau hauv qhov kev ua ntawm lub zog sab nraud, yog li nws muaj lubricity, txo qhov hnav zoo thiab coefficient sib txhuam qis.
3. Kev tiv thaiv tshuaj lom neeg zoo heev.
Cov graphite uas nthuav dav lawm raug xeb hauv cov xov xwm oxidizing muaj zog xws li nitric acid thiab concentrated sulfuric acid, tab sis tsis tshua muaj nyob rau hauv lwm cov kua qaub, cov hauv paus thiab cov kuab tshuaj.
4. tus nqi rov qab siab dua
Thaum tus thawj coj tseem ceeb lossis lub tes tsho ncej yog eccentric hauv kev tsim khoom thiab kev teeb tsa, nws muaj kev ua tau zoo txaus, thiab txawm tias graphite tawg, nws tuaj yeem kaw zoo, kom ntseeg tau tias nruj thiab tiv thaiv kev xau.
Furuite graphite siv cov flake graphite ntuj ua cov khoom siv raw los muab cov neeg siv khoom nrog ntau tshaj kaum cov lus qhia ntawm cov khoom graphite xws li nthuav dav graphite, flake graphite thiab graphite hmoov rau kev tshuaj ntsuam hauv chaw kuaj mob. Cov lus qhia tiav, zoo, txais tos yuav.
