• Cov khoom siv hluav taws xob:Siv rau kab hlau rauv taws thiab qhov cub vim nws muaj peev xwm tiv taus qhov kub thiab txias heev yam tsis yaj.
• Cov Khoom Siv Sib Xyaws:Ua kom cov polymers thiab cov hlau muaj zog, tsim cov khoom sib dua tab sis muaj zog heev rau kev lag luam aerospace thiab automotive.

Cov Kev Xav Tseem Ceeb Thaum Yuav KhoomNtuj Flake Graphite

Thaum xaiv tus neeg muag khoom, xav txog cov yam tseem ceeb no kom ntseeg tau tias koj tau txais cov khoom siv zoo tshaj plaws rau koj cov kev xav tau:

• Kev huv thiab cov ntsiab lus carbon:Xyuas kom tseeb tias cov graphite huv si raws li koj cov kev cai tshwj xeeb. Cov pa roj carbon ntau dua feem ntau yog qhov tsim nyog rau cov ntawv thov ua haujlwm siab.
• Qhov Loj ntawm Cov Nplaum:Qhov loj ntawm cov graphite flakes cuam tshuam rau kev ua haujlwm hauv ntau daim ntawv thov. Cov flakes loj dua feem ntau yog siv rau cov khoom siv refractories thiab foils, thaum cov flakes me dua yog siv rau hauv roj teeb thiab coatings.
• Lub Koob Npe ntawm Tus Neeg Muab Khoom:Koom tes nrog ib tus neeg muag khoom uas muaj npe nrov uas muab cov khoom zoo tas li, kev nrhiav khoom pom tseeb, thiab kev txhawb nqa kev siv tshuab txhim khu kev qha.

Kev Txheeb Xyuas

Cov khoom siv graphite ntujyog lub hauv paus tseem ceeb ntawm kev tsim kho tshiab hauv kev lag luam niaj hnub no. Nws cov hluav taws xob zoo heev, lubricity zoo dua, thiab lub zog muaj zog ua rau nws yog ib qho tseem ceeb hauv txhua yam los ntawm cov roj teeb uas muab zog rau peb lub ntiaj teb mus rau cov ntaub ntawv siab heev uas tsim peb lub neej yav tom ntej. Los ntawm kev nkag siab thiab siv cov khoom tshwj xeeb ntawm cov mineral no, cov lag luam tuaj yeem tau txais txiaj ntsig zoo hauv kev sib tw, tsav kev ua tau zoo thiab kev ua haujlwm zoo thoob plaws lawv cov khoom.

Cov Lus Nug Feem Ntau (FAQ)

Qhov txawv tseem ceeb ntawm graphite flake ntuj thiab graphite tsim yog dab tsi?

Cov graphite flake ntuj yog khawb los ntawm lub ntiaj teb thiab muaj cov qauv crystalline tshwj xeeb, thaum cov graphite tsim los ntawm petroleum coke lossis thee tar pitch los ntawm cov txheej txheem graphitization kub siab. Cov graphite flake ntuj feem ntau pheej yig dua thiab muaj cov khoom tshwj xeeb uas tsis pom muaj nyob rau hauv nws cov khoom sib xyaw.
