Muaj zog npaum li cas yog graphite pas nrig

Lub graphite pas nrig muaj zog npaum li cas?

Raws li ib qho tseem ceeb muaj cov khoom siv carbon, nruab nrab - ntxhib grain graphite plays lub luag hauj lwm tseem ceeb nyob rau hauv ntau yam high -end manufacturing sectors vim nws cov cim physicochemical zog. Nruab nrab-cov khoom ntxhib graphite rods yog tsim los siv cov khoom siv graphite raws li cov khoom siv raw los ntawm cov txheej txheem nyuaj, suav nrog extrusion molding, ci, impregnation, thiab siab -kub graphitization.

Lub zog yog qhov tseem ceeb ntawm cov khoom nruab nrab - ntxhib grain graphite rods thaum siv los ua cov khoom siv; Cov ntsuas lub zog tseem ceeb suav nrog lub zog compressive thiab flexural zog. Kev ua tau zoo sib txawv nyob ntawm cov qib tshwj xeeb thiab kev tsim khoom. Cov yam ntxwv ntawm lub zog no ua rau cov pas nrig tuaj yeem tiv taus kev siv tshuab siab thiab khoov kev ntxhov siab, ua tau raws li qhov yuav tsum tau ua hauv kev ua haujlwm ntawm ntau hom kev ua haujlwm.

Hardness yog ib qho tseem ceeb rau kev ntsuas cov khoom tiv thaiv rau hauv zos indentation lossis hnav. Lub hardness ntawm nruab nrab -coarse grain graphite rods yog feem ntau qhia siv lub Shore hardness (HS) nplai. Nws yog ib qho tsim nyog sau cia tias graphite feem ntau raug cais raws li cov khoom muag muag ntawm Mohs hardness nplai (kwv yees li 1.5-3), qhov system txawv ntawm Shore hardness nplai. Qhov no hardness profile txhais tau hais tias nruab nrab - ntxhib grain graphite rods muaj qhov sib npaug ntawm hnav tsis kam thiab yooj yim ntawm precision machining, tso cai rau lawv yuav tsum fabricated rau hauv cov khoom nrog complex geometries.

Tus nqi ntawm nruab nrab - ntxhib grain graphite rods stems los ntawm lawv cov array ntawm zoo heev zog. Ua ntej, lawv pom zoo heev - kub tsis kam, nrog lub melting point siab li 3850℃± 50℃thiab tsawg heev cov ntaub ntawv poob nyob rau hauv ultra-siab- kub ib puag ncig. Qhov thib ob, lawv muaj cov thermal shock tsis kam thiab qis coefficient ntawm thermal expansion, ua rau lawv tiv taus kub hloov pauv sai yam tsis muaj kev tawg. Tsis tas li ntawd, lawv muaj cov hluav taws xob zoo thiab thermal conductivity nrog rau cov tshuaj lom neeg ruaj khov, tiv thaiv corrosion los ntawm feem ntau cov kua qaub, alkalis, thiab cov kuab tshuaj organic. Kev siv cov txiaj ntsig zoo no, nruab nrab-cov graphite rods ntxhib pom cov ntawv thov thoob plaws ntau yam kev lag luam. Hauv kev lag luam metallurgical thiab tshuaj lom neeg, lawv tau siv los tsim cov khoom siv siab -kub-cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom tiv thaiv corrosion{14}}cov khoom siv tiv taus. Hauv kev lag luam ntawm cov tshuab thiab pwm tsim, lawv ua cov khoom siv hluav taws xob zoo tshaj plaws rau Kev Siv Hluav Taws Xob Hluav Taws Xob (EDM) thiab yog siv los tsim kub- nias pwm, casting pwm, thiab ntau yam khoom siv xws li cov kabmob thiab cov ntsaws ruaj ruaj.

Nruab nrab-cov graphite ntxhib ua lub luag haujlwm tseem ceeb hauv kev lag luam siab - thev naus laus zis thiab lub zog tshiab. Lawv tau siv dav hauv cov khoom siv hluav taws xob thiab cov hnub ci photovoltaic xws li kub - cheeb tsam cheeb tsam - xws li cov cua sov thiab cov ntaub thaiv hluav taws xob - rau cov hluav taws xob monocrystalline silicon. Tsis tas li ntawd, lawv ua haujlwm raws li cov khoom siv thiab cov neutron moderators hauv aerospace thiab nuclear industries, thiab yog siv los ua cov pwm pwm hauv cov iav thiab cov khoom siv refractory los txhim kho cov yields.
