Inkcazo yeMveliso: igraphite
Umgubo wegraphite uthambile, omnyama ngwevu, unamafutha kwaye unokungcolisa iphepha. Ubunzima buyi-1-2, kwaye buyanda ukuya kwi-3-5 kunye nokunyuka kokungcola kunye nolwalathiso oluthe nkqo. Ubunzima obuthile yi-1.9-2.3. Ngaphantsi kwemeko yokwahlukaniswa kwe-oksijini, indawo yayo yokunyibilika ingaphezulu kwe-3000 ℃, enye yezona zimbiwa ezinokumelana nobushushu. Kwiqondo lokushisa kwegumbi, iimpawu zeekhemikhali ze-graphite powder zizinzile, azinakunyibilika emanzini, i-asidi ye-dilute, i-alkali edibeneyo kunye ne-organic solvents; izinto eziphathekayo zinokumelana nokushisa okuphezulu kunye ne-conductivity, kwaye inokusetyenziswa njengento ephikisayo, i-conductive, i-resistant-resistant kunye ne-lubricating material.
Ngenxa yesakhiwo sayo esikhethekileyo, igraphite inezi mpawu zilandelayo: 1. Ukumelana nokushisa okuphezulu: indawo yokunyibilika yegraphite yi-3850 ± 50 ℃, kwaye indawo yokubilisa yi-4250 ℃. Oko kukuthi, izinga lokunciphisa ubunzima kunye ne-coefficient yokwandiswa kwe-thermal kuncinci kakhulu xa usebenzisa i-arc sintering ye-ultra-high, kwaye amandla e-graphite ayanda ngokunyuka kweqondo lokushisa. Kwi-2000 ℃, amandla egraphite aphindwe kabini. 2. Ukuthambisa: ukuthambisa kwegraphite kuxhomekeke kubungakanani begraphite. Okukhona isikali sisikhulu, kokukhona sincinci i-coefficient yokhuhlane, kwaye kokukhona intsebenzo yokuthambisa ingcono. 3. Ukuzinza kweekhemikhali: i-graphite inozinzo oluhle lweekhemikhali kwiqondo lokushisa lokushisa, elichasene ne-asidi, i-alkali kunye ne-organic solvent corrosion. 4. I-Plastiki: igraphite inokuqina okuhle kwaye inokucinezelwa kumaphepha amancinci. 5. Ukumelana nokutshatyalaliswa kwe-Thermal: xa i-graphite isetyenziswe kwiqondo lokushisa, inokumelana nokutshintsha okukhulu kweqondo lokushisa ngaphandle komonakalo. Xa iqondo lokushisa liphakama ngokukhawuleza, umthamo wegraphite awuyi kutshintsha kakhulu kwaye akuyi kubakho ukuqhekeka.
Usebenzisa:
1. Njengezinto eziphikisayo: igraphite kunye neemveliso zayo zineempawu zokumelana nokushisa okuphezulu kunye namandla aphezulu. Zisetyenziselwa ikakhulu ukuvelisai-graphite cruciblekwishishini le-metallurgical, kwaye zisetyenziswa ngokuqhelekileyo njenge-arhente yokukhusela i-ingot yensimbi kunye ne-metallurgical furnace lining.
2. Njengesixhobo sokuthambisa esingagugiyo: igraphite isoloko isetyenziswa njenge-lubricant kumashishini oomatshini. Ioli yokuthambisa ngokuqhelekileyo ayifanelekanga kwisantya esiphezulu, ukushisa okuphezulu kunye noxinzelelo oluphezulu.
3. Igraphite inozinzo oluhle lweekhemikhali. Isetyenziswa kakhulu kwishishini le-petrochemical, i-hydrometallurgy, imveliso ye-asidi-base, i-synthetic fiber, i-papermaking kunye namanye amacandelo amashishini, anokugcina izinto ezininzi zetsimbi.
4. Igraphite ingasetyenziswa njengelothe yepensile, i-pigment kunye ne-ejenti yokupholisha. Emva kokulungiswa okukhethekileyo, igraphite inokwenziwa kwizinto ezahlukeneyo ezikhethekileyo zokusetyenziswa ngamasebe amashishini afanelekileyo.
