Sharaxaada Alaabta

Nadiifinta sare ee garaafka garaafka waa badeecada garaafka dhamaadka dhamaadka ah ee laga soo xulay macdanta garaafiga flake ee dabiiciga ah si qoto dheerna loo sifeeyay oo la farsameeyay. Waa walxo bir ah oo aan shaqaynayn{2}

Tilmaamaha Muhiimka ah

1. Ultra{1}Nadiif sare

(1) Tani waa astaanta ugu muhiimsan. Waxa ku jira kaarboonka go'an ee garaafka sare -nadiifinta flake graphite badiyaa wuu ka weyn yahay ama la mid yahay 99.9%,{4}}dhamaadka alaabadu waxay gaadhi karaan wax ka wayn ama la mid ah 99.95%, Ka wayn ama la mid ah 99.99%, ama xataa ka sareeya.

(2) Ultra{1}}Waxyaabaha dambaska hooseeya: oo u dhiganta nadiifinta sare waa wax aad u hooseeya oo wasakhaysan, badiyaa in ka yar ama la mid ah 0.1%, sare{3}}waxa ku jira dambaska darajada<0.01%.

(3) Noocyo wasakhnimo oo yar oo gaar ah: walxaha wasakhda haraaga ah ee ugu muhiimsan waxaa ku jiri kara cadadka Fe, S, Si, Al, Ca, iwm, kuwaas oo u baahan in si adag loo xakameeyo si loo buuxiyo shuruudaha codsiyada dhamaadka-

2. Miisaanka gaarka ah - sida qaab-dhismeedka crystal

(1) Waxay haysaa qaab dhismeedka lakabka qumman ee qumman ee garaafiga cabbirka dabiiciga ah, kaas oo u eg xaashi ama miisaan yar. Qaab dhismeedkani wuxuu go'aamiyaa sifooyinka jidheed ee aadka u fiican.

(2) The advantage of large flakes: The value of large flakes is often in retaining a larger sheet diameter size (usually>150 mesh / 100µm, ama xataa ka weyn sida +80 mesh, +50 mesh). Jeexjeexyada waaweyni waxay leeyihiin faa'iidooyin badan oo ku saabsan dhismaha shabakada korantada, saliidaynta iyo diyaarinta graphene ee ballaarinta.

(3) Kala-soocidda: Marka loo eego cabbirka chip-ka (sida caadiga ah waxaa lagu qiyaasaa mesh ama mm), waxaa loo qaybin karaa miisaan ballaaran, cabbir dhexdhexaad ah, miisaan wanaagsan iyo garaafka nadiifka sare si loo buuxiyo shuruudaha codsiga kala duwan.

3. Sifooyin jidheed iyo kiimiko oo aad u wanaagsan

(1) Koronto oo aad u wanaagsan: Korontada korantada ee naxaastu waxay qiyaastii 4 jeer ka badan tahay naxaasta, korantada sare waxay ka dhigaysaa mid aad ugu habboon beero u baahan buuxinyaal.

(2) Daawaynta kulaylka heer sare ah: heerkulka kulaylka ee lakabka ayaa ah mid aad u fiican, waana wax wanaagsan oo kuleyl ah.

(3) Saliid sare (iskuxiran iskuxiran oo hooseeya): qaab dhismeedkiisa lakabka ah wuxuu ka dhigayaa lakabka garaafyada si sahlan loo simbiriirixo, taasoo bixisa sifeyn hufan.

(5) Iska caabbinta daxalka: waxay leedahay xasilooni kiimikaad aad u wanaagsan inta badan asiidhyada, alkalisyada iyo dareerayaasha organic.

(6) Caagagga / dahaarka: jilicsanaanta jilicsan, fududahay in la isku daro walxaha kale, waxaa lagu farsameyn karaa lakabyo, dufan, filim iyo qaabab kale.

(7) Isku xidhka ballaadhinta kulaylka hooseeya: qallafsanaanta yar ee heerkulka sare iyo xasilloonida cabbirka wanaagsan.

(8) Antioxidation: in kasta oo ka hooseeya nadiifnimada sare ee garaafka macmalka ah, laakiin xasilloonida wanaagsan ee heerkulka yaraa iyo aan{1}}osaydhiyeyaalayn bey'ad dhexdhexaad ah.

Shuruudaha kala soocidda

By purity: C> 99.9% (3N), C> 99.95% (3N5), C> 99.99% (4N), C> 99.995% (4N5), C>99.999% (5N) iyo wixii la mid ah.
Dhexroor ahaan (baaritaan): loo sameeyay si waafaqsan heerarka kala duwan ama shuruudaha, sida +50 mesh, +80 mesh, +100 mesh, +150 mesh, -325 mesh, iwm.
Sida laga soo xigtay index codsiga kama dambaysta ah, tusaale ahaan, waxaa si gaar ah loo isticmaalo graphite daahirnimo sare for maaddooyinka lithium anode iyo garaafka daahirsanaanta sare ee reactors nuclear.
