Izakhiwo zama-graphite bearings

Izakhiwo zama-graphite bearings

1. Ukuzinza okuhle kwamakhemikhali
I-graphite iyinto eqinile kumakhemikhali, futhi ukuzinza kwayo kwamakhemikhali akukho ngaphansi kwalokho kwezinsimbi eziyigugu. Ukuncibilika kwayo esiliva elincibilikisiwe kungu-0.001% kuphela - 0.002%.I-graphiteayincibiliki kuzincibilikisi zemvelo noma ezingaphili. Ayigqwali futhi incibilike kuma-asidi amaningi, izisekelo nosawoti.
2. Ukumelana nokushisa okuphezulu kwe-graphite bearing
Ngokusebenzisa izivivinyo, izinga lokushisa lesevisi lama-carbon grade bearings jikelele lingafinyelela ku-350 ℃; Metal graphite eziveza futhi 350 ℃; I-electrochemical graphite grade bearing ingafinyelela ku-450-500 ℃ (ngaphansi komthwalo okhanyayo), izakhiwo zayo ezingokomzimba nezomshini zihlala zingashintshiwe, futhi izinga lokushisa layo lesevisi lingafinyelela ku-1000 ℃ ngaphansi kwe-vacuum noma umkhathi ovikelayo.
3. Ukusebenza okuhle kokuzithambisa
I-graphiteinokusebenza okuhle kokuzithambisa ngezizathu ezimbili. Esinye sezizathu siwukuthi ama-athomu ekhabhoni akulethi ye-graphite ahlelwe endizeni ngayinye ngendlela evamile eyi-hexagonal. Ibanga eliphakathi kwama-athomu liseduze, elingu-0.142 nm, kanti ibanga eliphakathi kwezindiza liyi-0.335 nm, futhi zinyakaziswa komunye nomunye ngendlela efanayo. Indiza yesithathu iphinda indawo yendiza yokuqala, indiza yesine iphinda indawo yendiza yesibili, njalonjalo. Endizeni ngayinye, amandla okubopha phakathi kwama-athomu e-carbon anamandla kakhulu, kuyilapho ibanga phakathi kwezindiza likhulu, futhi amandla e-van der Waals phakathi kwazo abuthakathaka kakhulu, ngakho kulula ukushiya nokushelela phakathi kwezingqimba, okuyisizathu esiyisisekelo. kungani izinto ze-graphite zinezakhiwo zokuzigcoba.
Isizathu sesibili ukuthi izinto ze-graphite zinokunamathela okuqinile ngezinto eziningi zensimbi, ngakho-ke i-graphite exfoliated ingakwazi ukunamathela kalula endaweni yensimbi lapho igaya ngensimbi, yakha ungqimba lwensimbi.ifilimu ye-graphite, okuba ukungqubuzana phakathi kwe-graphite ne-graphite, ngaleyo ndlela kunciphisa kakhulu i-coefficient yokuguga kanye ne-friction, Lesi futhi esinye sezizathu zokuthi kungani ama-carbon graphite bearings abe nokusebenza okuhle kakhulu kokuzithambisa kanye nokusebenza kwe-antifriction.
4. Ezinye izakhiwo ze-graphite bearing
Uma kuqhathaniswa namanye ama-bearings,ama-graphite bearingsfuthi ibe ne-conductivity ephezulu yokushisa, i-coefficient ephansi yokunwetshwa komugqa, ukupholisa okusheshayo nokumelana nokushisa nokunye.
