Mwamakampani, ma graphite achilengedwe amagawidwa kukhala crystalline graphite ndi cryptocrystalline graphite molingana ndi mawonekedwe a kristalo. Ma crystalline graphite amapangidwa bwino, ndipo m'mimba mwake mwake ndi> 1 μm, yomwe nthawi zambiri imapangidwa ndi kristalo imodzi kapena kristalo wonyezimira. Crystalline graphite ndi imodzi mwa migodi 24 yodziwika bwino mdziko muno. Kufufuza ndi chitukuko cha graphite kwalembedwa mu National Mineral Resources Planning (2016-2020) kwa nthawi yoyamba. Kufunika kwa crystalline graphite kumatsogozedwa ndi malingaliro monga magalimoto atsopano amphamvu ndi graphene. Kuwonjezeka kwakukulu.
Malinga ndi US Geological Survey (USGS), chakumapeto kwa 2017, nkhokwe za graphite padziko lonse lapansi zili pafupifupi matani 270 miliyoni, zomwe zimagawidwa ku Turkey, China ndi Brazil, zomwe China imayendetsedwa ndi crystalline graphite ndi Turkey ndi cryptocrystalline graphite. Cryptocrystalline graphite ili ndi mtengo wochepa komanso chitukuko chochepa ndi chiyembekezo chogwiritsira ntchito, kotero crystalline graphite imatsimikizira mtundu wa graphite wapadziko lonse.
Malinga ndi Chinese Academy of Sciences, ma crystalline graphite aku China amapitilira 70% ya dziko lonse lapansi. Mwa iwo, zida za crystalline graphite za m'chigawo cha Heilongjiang zimatha kuwerengera 60% ya China komanso 40% yapadziko lonse lapansi, zomwe zimatenga gawo lalikulu. Mayiko amene amapanga crystalline graphite padziko lonse lapansi ndi China, kenako India ndi Brazil.
Kugawa kwazinthu
Geological maziko a crystalline graphite madipoziti m'madera osiyanasiyana China
Makhalidwe a ma crystalline graphite madipoziti ku China ndi zokolola za sikelo yayikulu (> 0.15mm)
Chigawo cha Heilongjiang
Chigawo cha Heilongjiang chili ndi ma graphite ambiri, ndipo akadali abwino kwambiri ku Hegang ndi Jixi. Dera lake lakum'mawa ndiye malo osungiramo ma crystalline graphite mdziko muno, omwe ali ndi ma graphite akuluakulu komanso akulu kwambiri monga Jixi Liumao, Luobei Yunshan ndi Muling Guangyi. Migodi ya graphite yapezeka m’mizinda 7 mwa 13 ya m’chigawochi. Zosungirako zomwe zikuyerekezedwa ndi pafupifupi matani 400 miliyoni, ndipo zomwe zingatheke ndi matani 1 biliyoni. Mudanjiang ndi Shuangyashan ali ndi zodziwikiratu zazikulu, koma mtundu wazinthu umaganiziridwa mozama. Ma graphite apamwamba kwambiri akadali olamulidwa ndi Hegang ndi Jixi. Akuti nkhokwe zobwezeretsedwa za graphite m'chigawochi zitha kufika matani 1-150 miliyoni (kuchuluka kwa mchere).
Inner Mongolia Autonomous Region
Zosungirako za crystalline graphite ku Inner Mongolia ndi zachiwiri kwa Heilongjiang, zomwe zimagawidwa ku Inner Mongolia, Xinghe, Alashan ndi Baotou.
Gawo la carbon of graphite ore m'dera la Xinghe nthawi zambiri limakhala pakati pa 3% ndi 5%. Kukula kwa sikelo ndi> 0.3mm, kuwerengera pafupifupi 30%, ndipo sikeloyo ndi> 0.15mm, yomwe imatha kufika kupitirira 55%. M'dera Alashan, kutenga Chahanmuhulu graphite gawo mwachitsanzo, kalasi avareji wa ore osasunthika mpweya ndi za 5.45%, ndipo ambiri mamba graphite ndi> 0,15 mm. Mgodi wa graphite m'dera la Chaganwendu ku Damao Banner m'dera la Baotou uli ndi mpweya wokhazikika wa 5.61% ndi mainchesi ambiri <0.15mm.
Chigawo cha Sichuan
Zida za crystalline graphite m'chigawo cha Sichuan zimagawidwa makamaka ku Panzhihua, Bazhong ndi Aba Prefectures. Avereji ya kaboni wokhazikika mu miyala ya graphite m'madera a Panzhihua ndi Zhongba ndi 6.21%. Ore ndi mamba ang'onoang'ono, ndipo kukula kwake sikuposa 0.15mm. Gawo la carbon of crystalline graphite ore ku Nanjiang ku Bazhong City ndi 5% mpaka 7%, lalitali kwambiri ndi 13%, ndipo masikelo ambiri a graphite ndi> 0.15 mm. Gawo la carbon of graphite ore ku Aba Prefecture ndi 5% ~ 10%, ndipo masikelo ambiri a graphite ndi <0.15mm.
Chigawo cha Shanxi
Chigawo cha Shanxi chapeza magwero a 8 a nkhokwe zodziwika bwino za crystalline graphite minerals, zomwe zimagawidwa kudera la Datong. Avereji ya kaboni wokhazikika m'gawoli nthawi zambiri imakhala pakati pa 3% ndi 4%, ndipo masikelo ambiri a graphite ndi> 0.15 mm. Mayeso ovala ore akuwonetsa kuti zokolola zofananira ndi pafupifupi 38%, monga mgodi wa graphite ku Qili Village, Xinrong District, Datong.
Chigawo cha Shandong
Zida za crystalline graphite m'chigawo cha Shandong zimagawidwa makamaka ku Laixi, Pingdu ndi Laiyang. Avereji ya kaboni wosasunthika kum'mwera chakumadzulo kwa nyumba ya Lai ndi pafupifupi 5.18%, ndipo makulidwe a mapepala ambiri a graphite ali pakati pa 0.1 ndi 0.4 mm. Avereji ya kaboni wosasunthika mumgodi wa graphite wa Liugezhuang ku Pingdu City ndi pafupifupi 3.34%, ndipo m'mimba mwake ndi <0.5mm. Pingdu Yanxin Graphite Mgodi ali ndi kalasi avareji ya kaboni yosasunthika ya 3.5%, ndi sikelo ndi> 0.30mm, yowerengera 8% mpaka 12%. Mwachidule, pafupifupi giredi ya carbon yokhazikika m'migodi ya graphite ku Shandong nthawi zambiri imakhala pakati pa 3% ndi 5%, ndipo gawo la masikelo> 0.15 mm ndi 40% mpaka 60%.
ndondomeko udindo
Madipoziti a graphite aku China ali ndi magiredi abwino a mafakitale, omwe ndi abwino kumigodi, ndipo kalasi ya crystalline graphite ndi yosachepera 3%. M'zaka 10 zapitazi, kutulutsa kwa graphite ku China kuli pakati pa matani 60,000 ndi 800,000, pomwe kupanga ma crystalline graphite kumakhala pafupifupi 80%.
Pali oposa chikwi mabizinesi processing graphite ku China, ndipo mankhwala ndi graphite mchere mankhwala monga sing'anga ndi mkulu mpweya graphite, mkulu chiyero graphite ndi graphite ufa wabwino, komanso kukodzedwa graphite ndi carbon zipangizo. Chikhalidwe cha bizinesiyo chimayendetsedwa ndi boma, chomwe chimagawidwa ku Shandong, Inner Mongolia, Hubei, Heilongjiang, Zhejiang ndi malo ena. Bizinesi ya migodi ya graphite yomwe ili ndi boma ili ndi maziko olimba komanso zabwino zambiri paukadaulo ndi zinthu.
Graphite chimagwiritsidwa ntchito zitsulo, zitsulo, foundry, zida makina, makampani mankhwala ndi madera ena chifukwa katundu wake kwambiri. Ndi kupita patsogolo kwa sayansi ndi ukadaulo, kuthekera kogwiritsa ntchito kwa zida zatsopano za graphite m'mafakitale apamwamba kwambiri monga mphamvu zatsopano, mafakitale a nyukiliya, zidziwitso zamagetsi, zakuthambo ndi chitetezo zikufufuzidwa pang'onopang'ono, ndipo zimawonedwa ngati njira yofunikira kuti ikwaniritse. chitukuko cha mafakitale omwe akubwera. Pakalipano, zinthu za graphite za ku China zimagwiritsidwa ntchito kwambiri pazinthu zowonongeka, zoponyera, zosindikizira, ma graphite apadera ndi madera ena, omwe amagwiritsidwa ntchito kwambiri ndi zipangizo zotsutsa ndi zoponya.
Ndi chitukuko chosalekeza cha makampani opanga mphamvu zatsopano, kufunikira kwa graphite m'tsogolomu kudzapitirira kuwonjezeka.
Zoneneratu zaku China za graphite mu 2020
