Umgubo wegrafiti ungasetyenziswa njengepensile, ngoko kutheni umgubo wegrafiti ungasetyenziswa njengepensile? Uyazi? Yifunde nomhleli!
Okokuqala, umgubo wegrafiti uthambile kwaye kulula ukuwusika, kwaye umgubo wegrafiti nawo uyathambisa kwaye kulula ukuwubhala; Ngokuphathelele isizathu sokuba ipensile ye-2B ifanele isetyenziswe kuvavanyo lokungena ekholejini, kufuneka kusetyenziswe umbane wayo. Okwesibini, ngokweempawu zeekhemikhali, umgubo wegrafiti wenziwe nge-C element, kwaye iimpawu zeekhemikhali ze-C element zizinzile kubushushu begumbi, ngoko ke ukusebenzisa ipensile yomgubo wegrafiti ukurekhoda iifayile kunokonga ixesha elide.
Umgubo wegrafiti uneempawu ezikhethekileyo ezilandelayo ngenxa yesakhiwo sawo esikhethekileyo:
1) Ukumelana nobushushu obuphezulu: Umgubo wegrafiti uneqondo lokunyibilika eliyi-3850 50℃ kunye neqondo lokubila eliyi-4250℃. Nokuba utshiswe yi-arc yobushushu obuphezulu kakhulu, ukwehla kobunzima kunye ne-thermal expansion coefficient zincinci kakhulu. Amandla omgubo wegrafiti ayanda ngokunyuka kobushushu, kwaye amandla omgubo wegrafiti aphindaphindeka kabini kwi-2000℃.
2) Ukuqhuba kunye nokuqhuba ubushushu: Ukuqhuba komgubo wegrafiti kungaphezulu ngokuphindwe kalikhulu kunee-ore ezingezizo zesinyithi. Ukuqhuba kobushushu kudlula oko kwezinto zesinyithi ezifana nentsimbi, isinyithi kunye ne-lead. Ukuqhuba kobushushu kuyancipha ngokunyuka kobushushu, kwaye nokuba kubushushu obuphezulu kakhulu, umgubo wegrafiti uba yi-insulator. Umgubo wegrafiti unokuqhuba umbane kuba iathom nganye yekhabhoni kwi-graphite powder yenza kuphela iibhondi ezintathu ze-covalent kunye nezinye iiathom zekhabhoni, kwaye iathom nganye yekhabhoni isagcina i-electron enye yasimahla yokudlulisa itshaja.
3) Ukuthambisa: Ipropati yokuthambisa yegrafiti powder ixhomekeke kubukhulu beesikali zegrafiti powder. Okukhona iisikali zikhulu, kokukhona i-friction coefficient incinci kwaye kokukhona ipropati yokuthambisa ingcono.
4) Uzinzo lweekhemikhali: Umgubo wegrafiti unozinzo oluhle lweekhemikhali kubushushu begumbi, kwaye unokumelana nokugqwala kwe-asidi, i-alkali kunye ne-organic solvent.
5) Ukuqina kweplastiki: Umgubo wegrafiti uqinile kakuhle kwaye ungagaywa ube ziingceba ezincinci.
6) Ukumelana nobushushu: Umgubo wegrafiti unokumelana notshintsho olukhulu lobushushu kubushushu begumbi ngaphandle kokonakala. Xa ubushushu butshintsha ngequbuliso, umthamo womgubo wegrafiti awutshintshi kakhulu kwaye imifantu ayizukubakho.
Thenga umgubo wegrafiti, wamkelekile kwiQingdao Furuite Graphite Factory, siza kukunika inkonzo eyanelisayo, ukuze ungabi naxhala!
