Isizathu se-electrolysis yentonga yegrafiti

Iimeko zokwenza iseli ye-electrolytic: Umbane we-DC. (1) Umbane we-DC. (2) Ii-electrode ezimbini. Ii-electrode ezimbini ezidityaniswe ne-positive pole yombane. Phakathi kwazo, i-electrode elungileyo edityaniswe ne-positive pole yombane ibizwa ngokuba yi-anode, kwaye i-electrode edityaniswe ne-negative pole yombane ibizwa ngokuba yi-cathode. (3) Isisombululo se-Electrolyte okanye i-electrolyte enyibilikisiweyo.I-Electrolyteisisombululo okanye isisombululo 4, ii-electrode ezimbini kunye ne-electrode reaction, i-anode (eqhagamshelwe kwi-positive pole yombane): i-oxidation reaction anode (eqhagamshelwe kwi-positive pole yombane): i-oxidation reaction cathode (eqhagamshelwe kwi-negative pole yombane): i-reduction reaction cathode (eqhagamshelwe kwi-negative pole yombane): i-reduction reaction cathode (eqhagamshelwe kwi-negative pole yombane): i-reduction reaction (i-negative electrode connected): i-reduction group 1: i-electrolysis group 1: i-electrolysis ye-CuCl2 anode cathode chlorine.
     Igrafayithiyikristale yekhabhoni. Yinto engeyoyesinyithi enombala wesilivere ongwevu, ethambileyo nekhazimlayo yesinyithi. Ubulukhuni beMohs yi-1-2, ubunzima obuthile yi-2.2-2.3, kwaye ubuninzi bayo ngokubanzi yi-1.5-1.8.
Iqondo lokunyibilika kwe-graphite liqala ukuthamba xa lifikelela kwi-3000 ℃ kwi-vacuum kwaye lidla ngokunyibilika. Xa lifikelela kwi-3600 ℃, i-graphite iqala ukunyibilika kwaye inyibilike. Amandla ezinto eziqhelekileyo ancipha kancinci kancinci xa kushushu kakhulu, ngelixa amandla e-graphite ephindwe kabini kunalawo kubushushu begumbi xa ishushu ukuya kwi-2000 ℃. Nangona kunjalo, ukumelana ne-oxidation kwe-graphite kuphantsi, kwaye izinga le-oxidation liyanda kancinci kancinci xa kushushu.
Iukuhanjiswa kobushushukwaye ukuhanjiswa kwegrafiti kuphezulu kakhulu. Ukuhanjiswa kwayo kuphindwe kane kunentsimbi engatyiwayo, kuphindwe kabini kunentsimbi yekhabhoni kwaye kuphindwe ka-100 kunentsimbi engeyiyo isinyithi iyonke. Ukuhanjiswa kwayo kobushushu akudluli nje kuphela kwizinto zesinyithi ezifana nentsimbi, isinyithi kunye nelothe, kodwa kuyancipha ngokunyuka kobushushu, obahlukileyo kwizinto zesinyithi iyonke. Igrafiti ide ibe yi-adiabatic kumaqondo obushushu ahlukeneyo. Ke ngoko, ukusebenza kwe-insulation yobushushu yegrafiti kuthembekile kakhulu kumaqondo obushushu aphezulu.
I-Graphite ithambile kwaye iplastiki kakuhle. I-coefficient yokungqubana kwe-graphite ingaphantsi kwe-0.1. I-Graphite inokuphuhliswa ibe ngamaphepha aphefumlayo nacacileyo. Ubunzima be-graphite enamandla aphezulu bukhulu kangangokuba kunzima ukuyicubungula ngezixhobo zedayimani.
I-Graphite inozinzo lweekhemikhali, i-asidi kunyeukumelana ne-alkalikunye nokumelana nokugqwala kwesinyibilikisi sendalo. Ngenxa yokuba i-graphite ineempawu ezintle kakhulu ezichazwe apha ngasentla, isetyenziswa kakhulu kushishino lwanamhlanje.
