Ubuncedo bezixhobo zegraphite kunye nezinto zokufudumeza zombane kwi-vacuum furnace

Ngokuphuculwa kwenqanaba lesithando somlilo sevalve yokucoca isithando somlilo, unyango lobushushu bevacuum luneenzuzo ezizodwa, kwaye unyango lwe-vacuum lobushushu luye lwathandwa ngabantu abakushishino ngenxa yoluhlu lweenzuzo ezifana nokukhupha, ukukhupha, ukukhulula i-oksijini kunye ne-automation. Nangona kunjalo, kuyaphawuleka ukuba i-vacuum yokucoca ubushushu bomlilo inomgangatho ophezulu wokufudumeza kombane, njenge-deformation ephezulu yobushushu, i-fracture I-Volatilization iye yaba yinto ebalulekileyo ethintela ukuphuhliswa kombane.isithando somlilo.
Ukuze kusonjululwe le ngxaki, ishishini lajika ingqalelo yalo kwigraphite.Igraphiteyenziwe ngezinye iintsimbi kwaye ineenzuzo ezingenakulinganiswa. Kuyaqondwa ukuba igraphite iphantse idume kwiindidi ezahlukeneyo zokucoca ubushushu be-vacuum njengento yokufudumeza kombane.
Emva koko iingenelo zegraphite vacuum unyango ubushushu bombane izinto zokufudumeza
1) Ukumelana nobushushu obuphezulu: indawo yokunyibilika yegraphite yi-3850 ± 50 ℃ kunye nenqanaba lokubilisa yi-4250 ℃. Nangona itshiswa yi-arc ye-ultra-high, ukulahleka kwesisindo kuncinci kakhulu kwaye i-coefficient yokwandiswa kwe-thermal incinci kakhulu. Amandla egraphite ayanda ngokunyuka kwamaqondo obushushu. Kwi-2000 ℃, amandla egraphite aphindwe kabini.
I-2) I-Conductivity kunye ne-thermal conductivity: i-conductivity ye-graphite iphindwe ngamaxesha angama-100 ngaphezu kwe-general non-metallic minerals. I-Thermal conductivity idlula intsimbi, intsimbi, ilothe kunye nezinye izinto zetsimbi. I-conductivity ye-thermal iyancipha ngokunyuka kweqondo lokushisa. Kwanakwiqondo lobushushu eliphakamileyo kakhulu, igraphite iba sisigqubuthelo-mandla. Igraphite inokuqhuba umbane ngenxa yokuba iathom yekhabhoni nganye kwigraphite yenza iibhondi ezintathu ezidibeneyo kunye nezinyeikhabhoniiiathom, kunye ne-athom yekhabhoni nganye igcina i-electron enye yasimahla yokudlulisela intlawulo.
3) Ukuthambisa: ukusebenza kokuthanjiswa kwegraphite kuxhomekeke kubungakanani besikali segraphite. Okukhona sikhulu isikali, sincinci i-coefficient ye-friction, kwaye ngcono ukusebenza kokuthambisa. Uzinzo kwiChemical:igraphiteinozinzo oluhle lweekhemikhali kwiqondo lobushushu begumbi kwaye inokumelana ne-asidi, i-alkali kunye ne-organic solvent corrosion.
I-4) I-Plastiki: i-graphite inobunzima obuhle kwaye inokugutyungelwa kumaphepha amancinci kakhulu. Ukuxhathisa ukutshatyalaliswa kwe-Thermal: xa i-graphite isetyenziselwa ubushushu begumbi, inokumelana nokutshintsha okukhulu kweqondo lokushisa ngaphandle komonakalo. Xa iqondo lokushisa litshintsha ngokukhawuleza, umthamo wegraphite utshintsha kancinci kwaye ukuqhekeka akuyi kwenzeka.
Xa uyila kunye nokucubungula isithando somlilo, kufuneka sicinge ukuba ukuchasana kwento yokufudumala yombane kutshintsha kancinci ngeqondo lokushisa kunye nokumelana nokuzinza, ngoko ke igraphite yinto ekhethiweyo.
