Hmoov graphite yog kub hauv kev lag luam, thiab nws ua lub luag haujlwm loj hauv ntau qhov chaw. Ua ntej, nws feem ntau hais tias hmoov graphite yog qhov kev daws teeb meem zoo tshaj plaws los tiv thaiv kev xeb ntawm cov khoom siv, thiab ntau tus neeg siv khoom tsis paub qhov laj thawj. Niaj hnub no, tus editor ntawm Furuite Graphite yuav piav qhia meej vim li cas koj hais li no:
Qhov ua tau zoo heev ntawm cov hmoov graphite ua rau nws yog qhov kev daws teeb meem zoo tshaj plaws los tiv thaiv kev xeb ntawm cov khoom siv.
1. Tiv taus qee qhov kub siab. Qhov kub ntawm kev siv hmoov graphite nyob ntawm hom khoom siv impregnation, xws li phenolic resin impregnated graphite tuaj yeem tiv taus 170-200 ℃, thiab yog tias ntxiv cov silicone resin impregnated graphite kom raug, nws tuaj yeem tiv taus 350 ℃. Thaum phosphoric acid tso rau ntawm carbon thiab graphite, qhov kev tiv thaiv oxidation ntawm carbon thiab graphite tuaj yeem txhim kho, thiab qhov kub ua haujlwm tiag tiag tuaj yeem nce ntxiv.
2. Kev ua kom sov zoo heev. Hmoov graphite kuj muaj kev ua kom sov zoo, uas siab dua li ntawm cov hlau ntawm cov khoom tsis yog hlau, qeb duas thawj zaug ntawm cov khoom tsis yog hlau. Kev ua kom sov yog ob npaug ntawm cov hlau carbon thiab xya npaug ntawm cov hlau tsis xeb. Yog li ntawd, nws tsim nyog rau cov khoom siv hloov pauv cua sov.
3. Kev tiv thaiv xeb zoo heev. Txhua yam carbon thiab graphite muaj kev tiv thaiv xeb zoo heev rau txhua qhov concentration ntawm hydrochloric acid, phosphoric acid thiab hydrofluoric acid, suav nrog cov xov xwm uas muaj fluorine. Qhov kub ntawm daim ntawv thov yog 350 ℃ -400 ℃, uas yog, qhov kub uas carbon thiab graphite pib oxidize.
4. Qhov saum npoo tsis yooj yim rau kev teeb tsa. Qhov "kev sib raug zoo" ntawm cov hmoov graphite thiab feem ntau cov xov xwm yog me me heev, yog li cov av tsis yooj yim lo rau ntawm qhov chaw. Tshwj xeeb tshaj yog rau cov khoom siv condensation thiab cov khoom siv crystallization.
Cov lus piav qhia saum toj no tuaj yeem ua rau koj nkag siab tob dua txog graphite hmoov. Qingdao Furuite Graphite tshwj xeeb hauv kev ua thiab tsim cov hmoov graphite, flake graphite thiab lwm yam khoom. Koj tuaj yeem tuaj xyuas thiab coj peb lub Hoobkas.
