Iipropati zeebheringi zegraphite

Iipropati zeebheringi zegraphite

1. Ukuzinza kakuhle kweekhemikhali
I-graphite yinto ezinzileyo kwiikhemikhali, kwaye ukuzinza kwayo kweekhemikhali akukho ngaphantsi kwezo zesinyithi ezixabisekileyo. Ukunyibilika kwayo kwisilivere etyhidiweyo yi-0.001% kuphela - 0.002%.Igraphiteayinyibiliki kwizinyibilikisi eziphilayo okanye ezingezozaphilayo. Ayina corrode kwaye inyibilike kwiiasidi ezininzi, iziseko kunye neetyuwa.
2. Ukumelana nobushushu obuphezulu bokuthwala igraphite
Ngokusebenzisa imifuniselo, ubushushu benkonzo yeebheringi zebakala lekhabhoni jikelele linokufikelela kuma-350 ℃; Ukuthwala i-Metal graphite ikwayi-350 ℃; I-electrochemical graphite grade bearing ingafikelela kwi-450-500 ℃ (phantsi komthwalo okhanyayo), iimpawu zayo zomzimba kunye nezomatshini zihlala zingatshintshi, kwaye ubushushu benkonzo yayo bunokufikelela kwi-1000 ℃ phantsi kwe-vacuum okanye umoya okhuselayo.
3. Ukusebenza kakuhle kokuzithambisa
Ukuthwala igraphiteinomsebenzi olungileyo wokuzithambisa ngezizathu ezibini. Esinye sezizathu sikukuba iiathom zekhabhoni ezikwilathisi yegraphite zilungelelaniswe kwinqwelo-moya nganye ngokwemilo yesiqhelo engama-hexagonal. Umgama phakathi kwe-athomu usondele, oyi-0.142 nm, ngelixa umgama phakathi kweendiza ngu-0.335 nm, kwaye zihamba zihamba ukusuka kwelinye icala. Inqwelo-moya yesithathu iphinda indawo yendiza yokuqala, inqwelo-moya yesine iphinda indawo yesibini, njalo njalo. Kwinqwelomoya nganye, amandla okubopha phakathi kwe-athom yekhabhoni yomelele kakhulu, ngelixa umgama phakathi kweenqwelomoya mkhulu, kwaye amandla e-van der Waals phakathi kwawo abuthathaka kakhulu, ngoko kulula ukushiya kunye nokutyibilika phakathi kweeleya, esona sizathu sisisiseko. kutheni izinto zegraphite zineempawu zokuzithambisa.
Isizathu sesibini kukuba izinto zegraphite zincamathele ngamandla kunye nezinto ezininzi zetsimbi, ngoko ke igraphite ekhutshiweyo inokubambelela ngokulula kumphezulu wesinyithi xa isila ngesinyithi, yenze umaleko wentsimbi.ifilimu yegraphite, eyaba yingxabano phakathi kwegraphite kunye negraphite, ngaloo ndlela inciphisa kakhulu i-coefficient yokunxiba kunye ne-friction, Esi sesinye sezizathu zokuba iibheringi ze-carbon graphite zinentsebenzo ebalaseleyo yokuzithambisa kunye nokusebenza kwe-antifriction.
4. Ezinye iimpawu zokuthwala igraphite
Xa kuthelekiswa nezinye iibheringi,iibheringi zegraphitekwakhona ibe ne-conductivity ephezulu ye-thermal, i-coefficient ephantsi yokwandiswa komgca, ukupholisa ngokukhawuleza kunye nokumelana nobushushu kunye nokunye.
