Impuphu yegrafiti ingasetshenziswa njengepensela, pho kungani impuphu yegrafiti ingasetshenziswa njengepensela? Uyazi? Yifunde nomhleli!
Okokuqala, i-graphite powder ithambile futhi kulula ukuyisika, kanti i-graphite powder nayo iyathambisa futhi kulula ukuyibhala; Ngokuqondene nokuthi kungani ipensela ye-2B kufanele isetshenziswe ekuhlolweni kokungena ekolishi, kufanele kusetshenziswe ukuhanjiswa kwayo. Okwesibili, ngokwezakhiwo zamakhemikhali, i-graphite powder yakhiwe nge-C element, kanti izakhiwo zamakhemikhali ze-C element zizinzile ngokulinganisela ekushiseni kwegumbi, ngakho-ke ukusebenzisa i-graphite powder pencil ukuqopha amafayela kungonga isikhathi eside.
I-graphite powder inezakhiwo ezilandelayo ezikhethekile ngenxa yesakhiwo sayo esikhethekile:
1) Ukumelana nokushisa okuphezulu: Impuphu ye-Graphite inephuzu lokuncibilika elingu-3850 50℃ kanye nephuzu lokubilisa elingu-4250℃. Ngisho noma ishiswa yi-arc yokushisa ephezulu kakhulu, ukwehla kwesisindo sayo kanye ne-thermal expansion coefficient kuncane kakhulu. Amandla empuphu ye-graphite ayanda ngokwanda kwezinga lokushisa, futhi amandla empuphu ye-graphite aphindeka kabili ku-2000℃.
2) Ukuqhuba kanye nokuqhuba ukushisa: Ukuqhuba kwempuphu ye-graphite kuphakeme ngokuphindwe kayikhulu kunokwama-ore ajwayelekile angewona awensimbi. Ukuqhuba ukushisa kudlula okokwezinto zensimbi ezifana nensimbi, insimbi kanye nomthofu. Ukuqhuba ukushisa kuyancipha ngokwanda kokushisa, futhi ngisho nasekushiseni okuphezulu kakhulu, impuphu ye-graphite iba yisivikelo. Impuphu ye-graphite ingaqhuba ugesi ngoba i-athomu ngayinye ye-carbon kumpuphu ye-graphite yakha kuphela izibopho ezintathu ze-covalent namanye ama-athomu e-carbon, futhi i-athomu ngayinye ye-carbon isagcina i-electron eyodwa yamahhala yokudlulisa ishaja.
3) Ukugcotshwa: Impahla yokugcoba yempuphu ye-graphite incike kusayizi wezikali zempuphu ye-graphite. Uma izikali zikhulu, i-friction coefficient iba ncane futhi i-lubricant iba ngcono.
4) Ukuqina kwamakhemikhali: Impuphu ye-Graphite iqinile kahle kwamakhemikhali ekushiseni kwegumbi, futhi ingamelana nokugqwala kwe-asidi, i-alkali kanye ne-organic solvent.
5) Ukuqina: Impuphu ye-graphite inokuqina okuhle futhi ingagaywa ibe yizicucu ezincane.
6) Ukumelana nokushaqeka kokushisa: Impuphu ye-graphite ingamelana noshintsho olukhulu lokushisa ekamelweni lokushisa ngaphandle kokulimala. Uma izinga lokushisa lishintsha ngokuzumayo, umthamo wempuphu ye-graphite awushintshi kakhulu futhi ngeke kwenzeke imifantu.
Thenga i-graphite powder, wamukelekile eQingdao Furuite Graphite Factory, sizokunikeza insizakalo eyanelisayo, ukuze ungakhathazeki!
