High quality thiab High quality Calcined Petroleum Coke Calcined Petroleum Coke
Daim ntawv thov
1. Nws tuaj yeem siv los ua roj rau boilers, chav-hluav taws xob symbiosis, cement kilns, thiab lwm yam.
2. Ua aluminium smelting anode electrodes
3. Ncaj nraim siv los ua cov pa roj carbon monoxide rau cov tshuaj xws li phosphorus elemental, calcium carbide, thiab silicon carbide.
4. Ua rau hauv electrodes rau zus tau tej cov elemental phosphorus, carbon dioxide, carbonization, thiab silicon carbide electric furnaces
5. Ua los ntawm graphite
Vim nws cov qauv tshwj xeeb, graphite recarburizer muaj cov khoom tshwj xeeb hauv qab no
1) Hom kub resistant: Lub melting point ntawm graphite yog 3850 ± 50 ° C thiab boiling point yog 4250 ° C.Txawm hais tias nws raug kub hnyiab los ntawm qhov kub thiab txias arc, qhov poob qis me me, thiab thermal expansion coefficient kuj me me heev.Lub zog ntawm graphite nce nrog nce kub, thiab ntawm 2000 ° C, lub zog ntawm graphite doubles.
2) Hluav taws xob thiab thermal conductivity: Cov hluav taws xob conductivity ntawm graphite yog ib puas npaug siab dua li cov khoom siv tsis yog hlau.Cov thermal conductivity tshaj cov khoom siv hlau xws li hlau, hlau, thiab txhuas.Lub thermal conductivity txo qis nrog qhov kub thiab txias, thiab txawm tias kub heev, graphite ua raws li thermal insulator.Graphite tuaj yeem ua hluav taws xob vim tias txhua cov pa roj carbon atom hauv graphite tsuas yog 3 covalent daim ntawv cog lus nrog rau lwm cov pa roj carbon atom, thiab txhua cov pa roj carbon atom tseem khaws 1 cov hluav taws xob dawb los xa cov nqi.
3) Lubricity: Lub lubricating kev ua tau zoo ntawm graphite nyob ntawm qhov loj ntawm graphite flakes.Qhov loj dua cov flakes, qhov me me ntawm kev sib txhuam coefficient thiab qhov zoo ntawm lubricating kev ua tau zoo.
4) Chemical stability: Graphite muaj tshuaj ruaj khov zoo ntawm chav tsev kub, thiab tiv taus acid, alkali thiab organic hnyav corrosion.
5) Plasticity: Graphite muaj qhov toughness zoo thiab tuaj yeem dov rau hauv cov ntawv nyias nyias.
6) Thermal shock resistance: Thaum graphite siv nyob rau hauv chav tsev kub, nws tuaj yeem tiv taus qhov kub thiab txias tsis muaj kev puas tsuaj.Thaum qhov kub hloov pauv tam sim ntawd, qhov ntim ntawm graphite hloov me ntsis, thiab cov kab nrib pleb yuav tsis tshwm sim.
