Carburizing siv ntau yam ntawm cov ntaub ntawv carbonaceous, xws li number case, petroleum coke, metallurgical coke thiab natural graphite. Nyob rau hauv lub ntiaj teb no steel carburizer graphite tseem yog ib tug ntawm cov tseem ceeb siv ntawm earthen graphite.Graphite thiab Graphitization Petroleum Coke yuav siv tau raws li carburizers nyob rau hauv lub steelmaking kev lag luam. Carburizing siv ntau yam ntawm cov ntaub ntawv carbonaceous, xws li number case, petroleum coke, metallurgical coke thiab natural graphite. Nyob rau hauv lub ntiaj teb no steel carburizer graphite tseem yog ib qho tseem ceeb ntawm kev siv earthen graphite.

Graphite yog dav siv nyob rau hauv kev lag luam hluav taws xob xws li electrode, txhuam, carbon pas nrig, carbon tube, zoo electrode ntawm mercury rectifier, graphite gasket, xov tooj qhov chaw, TV raj txheej thiab hais txog. Graphite electrode yog feem ntau siv nyob rau hauv smelting ntawm ntau yam hlau alloy, hlau alloy, yuav siv ntau tus graphite electrode. Cov graphite siv nyob rau hauv kev lag luam hluav taws xob, feem ntau cov particle loj thiab qib yuav tsum tau tshwj xeeb yog siab.

SUNGRAF'S Expandable Graphite yog siv dav hauv kev lag luam nplaim hluav taws. Cov ntaub ntawv tshwm sim tuaj yeem rov ua dua rau hauv ib qho yooj yim, tawv, thiab kub- thiab tshuaj-resistant ntawv nrog rau qib siab ntawm cohesive kev ncaj ncees. Expandable graphite kuj yog siv los ua ib qho active, char forming fire retardant nyob rau hauv non-structural polymers thiab coatings.

Lithium ion roj teeb yog lub roj teeb nruab nrab uas muaj ob qhov sib txawv lithium embedded tebchaw uas tuaj yeem thim rov qab thiab tshem tawm ntawm lithium ions yog siv los ua qhov zoo electrode thiab qhov tsis zoo electrode feem. Thaum them nyiaj, lithium ions raug tshem tawm ntawm qhov zoo electrode thiab embedded rau hauv qhov tsis zoo electrode los ntawm electrolyte thiab diaphragm. Nyob rau hauv ib qho kev tso tawm, ntawm qhov tod tes, lithium ions tshem tawm ntawm qhov tsis zoo electrode, dhau los ntawm electrolyte thiab diaphragm, thiab nkag mus rau hauv qhov zoo electrode. Lub anode ntawm lithium ion roj teeb yog tsim los ntawm kev sib xyaw anode active tshuaj, binder thiab additive los ua paste nplaum tusyees smeated ntawm ob sab ntawm tooj liab ntawv ci, tom qab ziab thiab dov.

Ntuj Graphite thiab Synthetic graphite yog tsim rau txhua yam kev sib txhuam cov khoom siv, cov khoom siv sib txhuam yog siv los tsim cov khoom siv sib txuas thiab cov khoom sib tsoo, cov khoom sib txhuam yog vam khom kev sib txhuam los ua lub braking thiab kis tau tus mob ntawm cov khoom siv, kev sib txhuam cov khoom tshwj xeeb graphite. hmoov yog ib hom kev npaj ntawm cov khoom sib txhuam, yog graphite hmoov nrog lubrication thiab hnav tsis kam, Cov khoom sib txhuam tshwj xeeb graphite hmoov thiab cob, roj hmab, cov khoom siv fiber ntau ntxiv, cov khoom sib txhuam yog cov khoom sib xyaw, cov khoom sib txhuam tshwj xeeb graphite hmoov tuaj yeem ua si. Lub luag haujlwm ntawm kev hnav tsis kam, kub tsis kam, thermal conduction, lubrication thiab lwm yam.

Graphite feem ntau yog siv los ua roj nplua nyeem hauv kev lag luam tshuab. Lubricating roj feem ntau tsis tuaj yeem siv rau ntawm kev kub ceev, kub kub, siab siab, thiab graphite tuaj yeem nyob ntawm 200 ℃ to 2000 ℃ kub thiab tseem nyob rau ntawm qhov siab zawv zawg ceev (LOOM / s) yam tsis muaj roj lubricating ua haujlwm. Ntau yam kev thauj mus los ntawm corrosive nruab nrab qee cov cuab yeej siv, feem ntau yog siv cov khoom siv graphite ua los ntawm piston rings, seals thiab bearings, lawv ua haujlwm, tsis tas yuav ntxiv cov roj lubricating, graphite kuj yog cov roj nplua nyeem zoo rau ntau cov hlau ua (xov hlau, cev rub).

Thermal conductive graphite daim ntawv yog cov khoom siv thermal conductive tshiab, uas ua rau cov cua sov sib npaug ntawm ob qho kev qhia, tiv thaiv cov khoom siv hluav taws xob thiab cov khoom siv thaum txhim kho kev ua haujlwm ntawm cov khoom siv hluav taws xob. Qhov sib xyaw ua ke ntawm thermal conductivity ua rau thermal graphite ib qho kev xaiv zoo tshaj plaws rau kev tswj xyuas thermal. Thermal conductive graphite ntawv muaj ultra-siab thermal conductivity nyob rau hauv thaj tsam ntawm 150-1500 W / MK hauv dav hlau.

Magnesium-carbon cib yog tsim ua tiav raws li ib qho ntawm magnesium-carbon refractories nyob rau hauv nruab nrab ntawm 1960s, ; Magnesium-carbon bricks tau siv dav hauv steelmaking yog li nws tau dhau los ua ib txwm siv graphite. Aluminium-carbon cib li aluminium-carbon refractory khoom yog tsuas yog siv rau nruam casting, ib tug tiv thaiv npog rau tiaj tus steel billet nws tus kheej- positioning pipeline, underwater nozzle thiab roj zoo tawg chim chim, thiab lwm yam. Cov khoom muaj feem xyuam, xws li cov khoom siv crucible, nkhaus caj dab lub raj mis, ntsaws thiab lub nozzle, lawv muaj hluav taws kub tsis kam, tsis tshua muaj thermal expansion, hlau melting txheej txheem, los ntawm hlau infiltration thiab yaig kuj ruaj khov, zoo thermal shock stability thiab zoo heev thermal conductivity ntawm kub kub. , Yog li graphite thiab nws cov khoom muaj feem xyuam yog siv dav hauv cov txheej txheem ntawm cov hlau melting ncaj qha.
