Nrog rau kev loj hlob sai ntawm kev lag luam thoob ntiaj teb, hmoov graphite tau raug suav hais tias yog ib qho ntawm cov khoom siv tseem ceeb hauv kev lag luam hauv tsev thiab txawv teb chaws. Tshwj xeeb tshaj yog nyob rau xyoo tas los no, nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, graphite tau ua lub luag haujlwm tseem ceeb hauv ntau yam lag luam.
Hauv kev lag luam, cov graphite ores raug muab faib ua ob pawg loj: crystalline graphite ores thiab stable crystalline graphite ores. Crystalline graphite ores tuaj yeem muab faib ua ob hom: flaky thiab dense.
Cov graphite ores hauv Suav teb feem ntau yog cov flaky crystalline hom, ua raws li cov cryptocrystalline hom. Cov graphite crystalline ntom ntom tsuas pom muaj nyob rau hauv ob peb qhov chaw xws li Tokbula hauv Xinjiang thiab muaj nqis me ntsis rau kev lag luam.
Cov graphite kev lag luam khaws cov khoom siv tshuaj lom neeg qub ntawm flake graphite, uas yog acid tsis kam, corrosion tsis kam thiab lub cev muaj zog, nrog rau kev tiv taus kub siab thiab qis. Nws lub zog compressive yog ntau dua 800kg / cm ², thiab nws tiv taus oxidation. Nws poob 1% ntawm nws qhov hnyav hauv 450 ℃ huab cua thiab muaj tus nqi rov qab ntawm 15-50%. Nws kuj muaj kev ua tau zoo heev ntawm graphite hmoov. Yog li ntawd, graphite tau siv dav hauv metallurgy, chemical engineering, petrochemicals, high-energy physics, aerospace, electronics thiab lwm yam teb.
Siv cov khoom ntawm graphite, tib neeg tau tsim ntau yam khoom raws li qhov xav tau ntawm kev tsim kho, xws li graphite purity siab, graphite yooj ywm, composite graphite, thiab lwm yam. Txhawm rau txhim kho nws cov kev ua tau zoo, graphite yog sib xyaw nrog cov fibers, graphite hlau xov hlau, hlau meshes thiab hlau ua phaj los ua graphite hmoov composite graphite, uas ua rau nws lub zog thiab elasticity ntau dua.
Cov graphite sib xyaw feem ntau yog nias txias lossis kub nrog cov resins, roj hmab hluavtaws thiab yas. Kuj tseem muaj cov graphite ua kua thiab cov graphite ib nrab kua.
Graphite ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, xws li kev kaw, kev tiv taus kub, kev tiv taus corrosion, kev ua hluav taws xob, kev khaws cia kub, kev tiv taus siab, kev tiv taus hnav thiab kev tiv taus oxidation, uas tau nyiam cov kws tshaj lij hauv tsev thiab txawv teb chaws. Tau kawg, graphite kuj nkag mus rau hauv cov khoom siv hauv chaw ua haujlwm niaj hnub no. Piv txwv li, lub Hoobkas khoom siv hauv Jiangxi xeev siv graphite los nthuav dav thiab ua nws mus rau hauv cov ntawv puag ncig uas tiv taus kab nrog qee qhov peev xwm los nqus cov tshuaj thiab tuaj yeem khaws lawv cov txiaj ntsig rau ib xyoos.
Vim yog qhov coefficient me me ntawm graphite thiab nws lub peev xwm los tiv taus qhov kub hloov pauv sai, nws tuaj yeem siv ua pwm rau cov khoom siv iav. Tom qab siv graphite, cov castings tau los ntawm cov hlau ferrous muaj qhov loj me, cov nplaim du, thiab cov txiaj ntsig siab. Lawv tuaj yeem siv yam tsis muaj lossis tsuas yog ua me ntsis xwb, yog li txuag tau ntau cov hlau. Hauv kev tsim cov txheej txheem hmoov metallurgy xws li cov hlau tawv, cov nkoj thiab cov tais diav rau kev sintering siab-resistant feem ntau yog ua los ntawm cov ntaub ntawv graphite. Tsis tas li ntawd, graphite kuj tseem tuaj yeem siv ua lub tshuab nqus tsev smelting graphite rwb thaiv tsev phaj thiab hauv paus, nrog rau cov khoom xws li cov raj cua sov kub-resistant, rods, phaj, thiab compartments.
