Synthetic graphite yog polycrystalline zoo ib yam li crystallography. Muaj ntau ntau yam khoom siv graphite thiab cov txheej txheem ntau lawm.
Hauv kev txiav txim siab dav dav, tag nrho cov khoom siv graphite tau txais tom qab carbonization ntawm cov organic teeb meem thiab graphitization ntawm qhov kub thiab txias tuaj yeem raug xa mus rau cov khoom siv graphite, xws li carbon (graphite) fiber, pyrolytic carbon (graphite), ua npuas ncauj graphite, thiab lwm yam.
Hauv kev nkag siab nqaim, cov khoom siv graphite feem ntau yog hais txog cov khoom siv ntau, xws li graphite electrode, isostatic graphite, ua los ntawm batching, mixing, molding, carbonization (paub tias roasting hauv kev lag luam) thiab graphitization, uas tsis muaj impurity cov ntsiab lus ntawm charcoal raw cov ntaub ntawv (petroleum coke, asphalt coke, thiab lwm yam).
Muaj ntau ntau hom kev dag graphite, suav nrog hmoov, fiber ntau thiab thaiv, thaum lub siab nqaim ntawm cov khoom siv graphite feem ntau yog thaiv, uas yuav tsum tau ua tiav rau hauv qee yam zoo thaum siv. Nws tuaj yeem suav tau tias yog hom khoom siv ntau theem, suav nrog graphite theem hloov pauv los ntawm cov pa roj carbon monoxide xws li roj av coke lossis asphalt coke, graphite theem hloov los ntawm cov thee pitch binder coated nyob ib ncig ntawm cov hais, cov khoom sib txuam lossis cov pores tsim los ntawm cov thee pitch binder tom qab kev kho cua sov, thiab lwm yam. Muaj kev tsim khoom ntawm cov khoom siv graphite, qib ntawm graphitization feem ntau tsawg dua 90%.
Piv nrog rau ntuj graphite, dag graphite muaj zog hloov hluav taws xob thiab hluav taws xob conductivity, lubricity thiab plasticity, tab sis dag graphite kuj muaj zoo hnav tsis kam, corrosion kuj thiab permeability tsawg tshaj li ntuj graphite.
Cov khoom siv raw rau kev tsim cov graphite feem ntau suav nrog roj av coke, koob coke, asphalt coke, thee pitch, carbon microspheres, thiab lwm yam.
Cov khoom siv ntawm cov khoom siv graphite feem ntau yog tshwm sim hauv cov hauv qab no:
1. Graphite electrode: Nrog roj av coke thiab koob coke li raw cov ntaub ntawv thiab thee pitch li binder, graphite electrode yog tsim los ntawm calcination, batching, mixing, pressing, roasting, graptitization thiab machining. Nws yog dav siv nyob rau hauv hluav taws xob rauv hlau, muaj silicon, daj phosphorus thiab lwm yam khoom siv los ntawm kev tso hluav taws xob lub zog nyob rau hauv daim ntawv ntawm arc kom sov thiab yaj tus nqi.
2. Pre-ci anode: ua los ntawm roj av coke li raw khoom thiab thee pitch li binder los ntawm calcination, batching, mixing, nias, roasting, impregnation, graphitization thiab machining, feem ntau yog siv raws li conductive anode ntawm electrolytic txhuas khoom.
3. Bearing, sealing nplhaib: conveying corrosive media khoom, dav siv dag graphite ua los ntawm piston rings, sealing rings thiab bearings, ua hauj lwm tsis ntxiv lubricating roj.
4. Thaum tshav kub kub exchanger, lim chav kawm: dag graphite muaj cov yam ntxwv ntawm corrosion kuj, zoo thermal conductivity thiab tsawg permeability. Nws yog dav siv nyob rau hauv kev lag luam tshuaj los ua kom kub exchanger, tshuaj tiv thaiv tank, absorber, lim thiab lwm yam khoom siv.
5. Tshwj xeeb graphite: nrog zoo roj av coke li raw khoom, thee pitch los yog hluavtaws cob raws li binder, los ntawm raw khoom npaj, batching, kneading, nias, crushing, sib tov kneading, molding, ntau roasting, ntau yam nkag, purification thiab graphitization, machining thiab ua, feem ntau suav nrog purity graphite graphite, nuclear graphite. aerospace, electronics, nuclear kev lag luam sectors.
