I-graphite powder ingasetyenziswa njengepensile, ngoko kutheni i-graphite powder ingasetyenziswa njengepensile? Ingaba uyazi? Yifunde kunye nomhleli!
Okokuqala, umgubo wegraphite uthambile kwaye kulula ukuwusika, kwaye umgubo wegraphite nawo uthambisa kwaye kulula ukuwubhala; Ngokumalunga nokuba kutheni kufuneka kusetyenziswe ipensile engu-2B kuviwo lokungena ekholejini, makusetyenziswe indlela yokuqhuba kwayo. Okwesibini, ngokweempawu zeekhemikhali, i-graphite powder yenziwe yi-C element, kunye neempawu zeekhemikhali ze-C element zizinzile kwiqondo lokushisa, ngoko ke ukusebenzisa ipensile ye-graphite powder ukurekhoda iifayile kunokugcina ixesha elide.
I-graphite powder inezi mpawu zilandelayo ezikhethekileyo ngenxa yesakhiwo sayo esikhethekileyo:
I-1) Ukumelana nokushisa okuphezulu: i-graphite powder ine-melting point ye-3850 50 ℃ kunye nendawo yokubilisa ye-4250 ℃. Nokuba itshiswe yi-arc yobushushu obuphezulu, ukuncipha kwayo kobunzima kunye nokwandiswa kwe-thermal coefficient incinci kakhulu. Amandla omgubo wegraphite ayanda ngokunyuka kwamaqondo obushushu, kwaye amandla omgubo wegraphite aphindaphindeka ku-2000℃.
I-2) I-Conductivity kunye ne-thermal conductivity: I-conductivity ye-graphite powder iphindwe kalikhulu ngaphezu kwe-ores jikelele engekho. I-Thermal conductivity idlula kwizinto zetsimbi ezifana nentsimbi, intsimbi kunye nelothe. I-conductivity ye-thermal iyancipha ngokunyuka kweqondo lokushisa, kwaye nakwiqondo lokushisa eliphezulu kakhulu, i-graphite powder iba yi-insulator. I-graphite powder inokuqhuba umbane ngenxa yokuba i-athomu yekhabhoni nganye kwi-graphite powder yenza kuphela i-covalent bonds ezintathu kunye nezinye ii-athom ze-carbon, kwaye i-athomu yekhabhoni nganye igcina i-electron enye yamahhala ukudlulisa intlawulo.
3) Ukuthambisa: Ipropathi yokuthambisa yomgubo wegraphite ixhomekeke kubungakanani bezikali zomgubo wegraphite. Okukhona izikali zikhulu, incinci i-coefficient ye-friction kwaye ingcono ipropathi yokuthambisa.
I-4) Uzinzo lweMichiza: Ipowder yegraphite inozinzo oluhle lweekhemikhali kwiqondo lokushisa, kwaye inokumelana ne-asidi, i-alkali kunye ne-organic solvent corrosion.
I-5) I-Plastiki: I-powder ye-graphite inobunzima obuhle kwaye inokugutywa ibe ngamaqhekeza amancinci.
I-6) Ukuxhatshazwa kwe-Thermal shock: I-graphite powder inokumelana nokutshintsha okukhulu kweqondo lokushisa kwiqondo lokushisa ngaphandle kokulimala. Xa iqondo lokushisa litshintsha ngokukhawuleza, umthamo we-graphite powder awutshintshi kakhulu kwaye ukuqhekeka akuyi kwenzeka.
Thenga i-graphite powder, wamkelekile kwi-Qingdao Furuite Graphite Factory, siya kukubonelela ngenkonzo eyanelisayo, ukuze ungabi naxhala!
