Sida laga soo xigtay xirfadlayaasha warshadaha graphite, isticmaalka adduunka oo dhan ee alaabta macdanta graphite waxay ka beddeli doontaa hoos u dhac ilaa kor u kac joogto ah sanadaha soo socda, taas oo la socota kororka wax soo saarka birta adduunka. Warshadaha refractory, waxa la filayaa in ay jiri doonto baahi weyn oo loo qabo qaar ka mid ah alaabooyinka garaafiga ah ee tayada wanaagsan. Maanta, tifaftiraha Furuite graphite ayaa kuu sheegi doona rajada iyo kartida graphite flake ee horumarinta warshadaha:
1. Qalab graphite ah ayaa si weyn loogu isticmaalaa alaabta refractory ee horumarsan iyo dahaarka warshadaha birta ah.
Jajabka graphite waxa loo isticmaalaa dib-u-soo-celin horumarsan iyo dahaar warshado badan. Sida leben kaarboon magnesia, crucibles, iwm Pyrotechnic wax stabilizer in industry military, desulfurization dardargelinta in warshadaha sifaynta, hogaanka qalin warshadaha iftiinka, burushka carbon in warshadaha korontada, electrode in warshadaha batteriga, kicinta in warshadaha bacriminta, iwm graphite Flake waa. kheyraad macdaneed oo muhiim ah oo leh faa'iidooyinka Shiinaha, iyo doorka ay ku leedahay tignoolajiyada sare, tamarta nukliyeerka iyo difaaca qaranka iyo warshadaha militariga ayaa sii kordheysa oo caan ah. Horumarinta warshadaha graphite waxay leedahay awood.
2. Garaafyada garaafyada sidoo kale waa kheyraad macdaneed oo aan macdan ahayn oo aad muhiim u ah.
Garaafyada Flake waa kheyraad macdaneed oo muhiim ah, kaas oo loo qaybin karo laba nooc: cryptocrystalline iyo crystalline iyadoo loo eegayo foomamka crystalline kala duwan. Budada graphite waa jilicsan iyo cawl madow; waxay leedahay dareen dufan waxayna wasakhayn kartaa warqad. Adaggu waa 1 ilaa 2, adkaantana waxaa lagu kordhin karaa 3 ilaa 5 iyada oo kororka wasakhdu ay u socoto jihada toosan. Culayska gaarka ah waa 1.9 ilaa 2.3. Marka la eego xaaladda go'doominta ogsijiinta, barta dhalaalkeedu waa ka sarreeyaa 3000 ℃, taas oo ah mid ka mid ah macdanta heerkulka u adkaysata. Waxaa ka mid ah, garaafyada microcrystalline waa badeecad metamorphic ah oo dhuxul ah, taas oo ah isku-dar cufan oo ka kooban kareemyo leh dhexroor ka yar 1 micron, oo sidoo kale loo yaqaan graphite earthy ama amorphous graphite; graphite crystalline waa badeecad metamorphic ah oo dhagax ah, oo leh kiristaalo waaweyn, oo u badan qolof leh. Sababtoo ah graphite flake wuxuu leeyahay sifooyin wanaagsan oo iska caabin heerkul sare ah, saliidayn, caabbinta shoogga kuleylka, xasiloonida kiimikada, korantada iyo kuleylka kuleylka, iwm.
Nuxurka kaarboonka iyo cabbirka walxaha graphite flake ayaa go'aamiya qiimaha suuqa ee alaabta. In kasta oo Shiinuhu uu weli noqon doono soo saaraha ugu weyn adduunka oo dhoofiya garaafyada flake dhawrka sano ee soo socda ama xitaa in ka badan toban sano, dalalka kale ee adduunka ayaa sidoo kale weeraraya booska Shiinaha. Gaar ahaan, dhowr waddan oo Yurub ah oo soo saara tiknoolajiyada casriga ah iyo waddamo Afrikaan ah oo soo koraya ayaa si firfircoon u horumarinaya kheyraadka waxayna kula tartamayaan Shiinaha kheyraadkooda macdanta tayada sare leh iyo alaabooyin jaban. Qiimaha dhoofinta alaabada budada garaafiga ah ee shiinaha ma aha mid sare, badi alaabta ceeriin iyo alaabta aasaasiga ah ee warshadaysan, oo leh maaddo tignoolajiyadeed hoose iyo faa'iido yar. Marka ay la kulmaan wadamo ka kharash yar macdan qodista alaabta ceeriin marka loo eego Shiinaha, sida wadamada Afrika, waa la soo bandhigi doonaa. Ku filnaansho la'aanta badeecada. Inkasta oo dalal yar oo adduunka ah ay ku hawlan yihiin macdanta ganacsiga ee kaydka budada garaafiga ah, awoodda wax-soo-saarka ee xad-dhaafka ah waxay sababtay tartan adag oo ka dhex jira alaab-qeybiyeyaasha suuqa.
Si aad u iibsato graphite flake, ku soo dhawoow warshadda graphite ee Furuite si aad u fahamto, waxaanu ku siin doonaa adeeg ku qanacsan, si aadan walwal uga qabin!
