Ukuhanjiswa kunye nophuhliso lwecrystalline graphite eTshayina

Kwimizi-mveliso, igraphite yendalo ihlelwa kwi-crystalline graphite kunye ne-cryptocrystalline graphite ngokwefomu yekristale.I-crystalline graphite iphuculwe ngcono, kwaye i-crystal plate diameter yi> 1 μm, eveliswa kakhulu yikristale enye okanye i-crystal flaky.Icrystalline graphite yenye yezimbiwa ezingama-24 ezicwangcisiweyo kweli lizwe.Ukuhlolwa nokuphuhliswa kwegraphite kudweliswe kuCwangciso lweMithombo yeziMbiwa kuZwelonke (2016-2020) okokuqala.Ukubaluleka kwe-crystalline graphite kukhokelwa yimiba efana neenqwelo zamandla amatsha kunye negraphene.Ukwanda okuphawulekayo.

Ngokutsho kwe-US Geological Survey (USGS), ekupheleni kuka-2017, iindawo zokugcina igraphite zehlabathi zimalunga ne-270 yezigidi zeetoni, ezisasazwa ikakhulu eTurkey, eChina naseBrazil, apho i-China ilawulwa yi-crystalline graphite kunye neTurkey yi-cryptocrystalline graphite.I-cryptocrystalline graphite inexabiso eliphantsi kunye nophuhliso olulinganiselweyo kunye nokusetyenziswa, ngoko ke i-crystalline graphite inquma ipateni yegraphite yehlabathi.

Ngokutsho kweAkhademi yaseTshayina yezeNzululwazi, igraphite yaseChina ithatha ngaphezu kwe-70% yetotali yehlabathi.Phakathi kwazo, izibonelelo zegraphite zePhondo laseHeilongjiang zingabalelwa kwi-60% yaseTshayina nangaphezulu kwe-40% yehlabathi, edlala indima ebalulekileyo.Abona bavelisi abakhulu becrystalline graphite yiTshayina, ilandelwa yiIndiya neBrazil.

IPhondo laseHeilongjiang

IPhondo laseHeilongjiang linosasazo olubanzi lwegraphite, kwaye lisagqwesa eHegang naseJixi.Ummandla wayo osempuma ngowona vimba mkhulu we-crystalline graphite elizweni, eneendawo ezidumileyo ezinkulu nezinkulu kakhulu zegraphite ezifana neJixi Liumao, uLuobei Yunshan kunye noMuling Guangyi.Imigodi yeGraphite ifunyenwe kwizixeko ezisi-7 kwezili-13 zeli phondo.Oovimba abaqikelelwayo bobutyebi bubuncinane bangama-400 ezigidi zeetoni, kwaye izibonelelo ezinokubakho zimalunga ne-1 yebhiliyoni yeetoni.I-Mudanjiang kunye ne-Shuangyashan zifumene izinto ezinkulu, kodwa umgangatho wemithombo uqwalaselwa ngokubanzi.Igraphite ekumgangatho ophezulu isalawulwa yiHegang kunye neJixi.Kuqikelelwa ukuba oovimba abafumanekayo begraphite kwiphondo banokufikelela kwi-1-150 yezigidi zeetoni (isixa semineral).
Ingingqi yeMongolia eZimeleyo

Oovimba becrystalline graphite kwi-Inner Mongolia yesibini kuphela kwi-Heilongjiang, isasazwa ikakhulu kwi-Inner Mongolia, i-Xinghe, i-Alashan kunye ne-Baotou.

Umgangatho wekhabhoni esisigxina yentsimbi ekrwada kummandla weXinghe uphakathi kwe-3% kunye ne-5%.Umlinganiselo wesikali ngu> 0.3mm, ubalwa malunga ne-30%, kwaye umlinganiselo wesikali ngu> 0.15mm, onokufikelela ngaphezu kwe-55%.Kwindawo yase-Alashan, ukuthatha idiphozithi yegraphite ye-Chahanmuhulu njengomzekelo, ibakala eliqhelekileyo le-ore esisigxina yekhabhoni limalunga ne-5.45%, kwaye uninzi lwezikali zegraphite> 0.15 mm.Umgodi wegraphite kwingingqi yeChaganwendu yeDamao Banner kwindawo yaseBaotou inomlinganiselo wekhabhoni esisigxina ye-5.61% kunye nedayamitha yesikali uninzi <0.15mm.
IPhondo laseSichuan

Ubutyebi bekristale begraphite kwiPhondo laseSichuan busasazwa ikakhulu kwiPanzhihua, Bazhong kunye neAba Prefectures.Umyinge womgangatho wekhabhoni esisigxina kwi-graphite ore kwiindawo zasePanzhihua naseZhongba yi-6.21%.I-ore ubukhulu becala izikali ezincinci, kwaye isikali sesikali asikho ngaphezu kwe-0.15mm.Umgangatho wekhabhoni emiselweyo yekristale ye-ore yegraphite kwindawo yaseNanjiang kwiSixeko saseBazhong yi-5% ukuya kwi-7%, elona liphezulu li-13%, kwaye uninzi lwezikali zegraphite zi>0.15 mm.Umgangatho wekhabhoni esisigxina ye-graphite ore kwi-Aba Prefecture yi-5% ~ 10%, kunye nezikali ezininzi zegraphite <0.15mm.
IPhondo laseShanxi

IPhondo laseShanxi lifumene imithombo ye-8 yemithombo ye-crystalline echongiweyo yeeminerali ze-crystalline graphite, ezisasazwa kakhulu kwindawo yaseDatong.Umyinge womgangatho wekhabhoni esisigxina kwidiphozithi ubukhulu becala uphakathi kwe-3% kunye ne-4%, kwaye uninzi lwezikali zegraphite zi>0.15 mm.Uvavanyo lwentsimbi ekrwada lubonisa ukuba isivuno esikhulu esihambelanayo simalunga nama-38%, njengomgodi wegraphite kwilali yaseQili, kwiSithili saseXinrong, eDatong.
IPhondo laseShandong

Imithombo ye-crystalline graphite kwiPhondo laseShandong isasazwa ikakhulu eLaixi, ePingdu naseLaiyang.Ibakala eliqhelekileyo lekhabhoni esisigxina kwi-villa esezantsi-ntshona yeLai malunga ne-5.18%, kwaye ububanzi bamaphepha amaninzi egraphite buphakathi kwe-0.1 kunye ne-0.4 mm.Umyinge womgangatho wekhabhoni esisigxina kwimigodi yegraphite yaseLiugezhuang kwiSixeko sasePingdu imalunga ne-3.34%, kwaye i-diameter yesikali ubukhulu becala <0.5mm.I-Pingdu Yanxin Graphite Mine ine-avareji yebakala lekhabhoni esisigxina ye-3.5%, kwaye isikali somlinganiselo ngu> 0.30mm, ibalwa kwi-8% ukuya kwi-12%.Ngamafutshane, umgangatho ophakathi wekhabhoni esisigxina kwimigodi yegraphite eShandong uphakathi kwe-3% kunye ne-5%, kwaye umlinganiselo wezikali>0.15 mm yi-40% ukuya kuma-60%.
ubume benkqubo

Iidiphozithi zegraphite zaseTshayina zinamabakala amahle emizi-mveliso, alungele ukumbiwa kwemigodi, kwaye ibakala legraphite yecrystalline alikho ngaphantsi kwe-3%.Kule minyaka ili-10 idlulileyo, imveliso ye-graphite yase-China iphakathi kwama-60,000 kunye nama-800,000 eetoni, apho imveliso ye-crystalline graphite yenza malunga nama-80%.

Kukho ngaphezu kwewaka lamashishini okulungisa igraphite eTshayina, kwaye iimveliso ziimveliso zezimbiwa zegraphite ezinje ngegraphite ephakathi nephezulu, igraphite yococeko oluphezulu kunye nomgubo ocolekileyo wegraphite, kunye negraphite eyandisiweyo kunye necarbon materials.Ubume beshishini bulawulwa ngurhulumente ikakhulu, esasazwa kakhulu eShandong, eMongolia yangaphakathi, eHubei, eHeilongjiang, eZhejiang nakwezinye iindawo.Ishishini likarhulumente lemigodi yegraphite linesiseko esiluqilima kunye neenzuzo ezibalulekileyo kubuchwepheshe kunye nemithombo.

Igraphite isetyenziswa ngokubanzi kwintsimbi, isinyithi, isiseko, izixhobo zoomatshini, ishishini lemichiza kunye namanye amasimi ngenxa yeempawu zayo ezintle.Ngenkqubela phambili yenzululwazi kunye nobuchwepheshe, amandla okusetyenziswa kwezinto ezintsha zegraphite kumashishini obuchwepheshe obuphezulu njengamandla amatsha, ishishini lenyukliya, ulwazi lwe-elektroniki, i-aerospace kunye nokhuselo luyaphononongwa ngokuthe ngcembe, kwaye kuthathwa njengomthombo weqhinga oyimfuneko uphuhliso lwamashishini asakhasayo.Okwangoku, iimveliso zegraphite zaseTshayina zisetyenziswa kakhulu kwizinto eziphikisayo, ukuphoswa, izitywina, iigraphite ezikhethekileyo kunye namanye amasimi, phakathi kwazo izinto eziphikisayo kunye nokuphosa zisetyenziswa kakhulu.

 

Ngophuhliso oluqhubekayo lweshishini elitsha lamandla, imfuno yegraphite kwixesha elizayo iya kuqhubeka ikhula.
