Los ntawm kev siv cov tshuab vapor deposition los siv cov txheej tuab zoo li silicon carbide (SiC) lossis tantalum carbide (TaC) mus rau graphite nto, oxygen tau thaiv zoo. Qhov no daws tau tag nrho graphite qhov tsis muaj zog ntawm qhov yooj yim oxidizing thiab hlawv ntawm qhov kub siab tshaj 400 degree.

Tseem ceeb Boosting Mechanical Strength thiab Hnav Resistance

Advanced reprocessing tsis tau tsuas yog ntxiv dag zog rau kev sib raug zoo ntawm cov graphite thiab lwm yam ntaub ntawv tab sis kuj ua rau cov khoom denser. Qhov no ua tau zoo txhim kho tag nrho hardness, compressive zog, thiab nto hnav tsis kam ntawm cov khoom hauv paus.

Sealing Pores thiab ua tiav huab cua zoo -Tightness

Advanced impregnation txheej txheem tob tob sau cov microscopic pores uas tsim thaum lub sij hawm graphite sintering. Qhov no tag nrho thaiv cov kua thiab cov pa tawm los ntawm kev hla, ua tau raws li cov huab cua nruj - nruj raws li qhov xav tau ntawm siab - cov khoom siv tshuaj lom neeg thiab cov khoom siv semiconductor.

Standard Graphite vs. Reprocessed Graphite

Thaum lub ntuj tsim los yog conventionally tsim graphite muaj lub hauv paus zoo, nws feem ntau poob qis thaum raug rau qhov chaw huab cua ntawm kev lag luam niaj hnub. Tom qab peb ua tiav peb cov thev naus laus zis "Purification, Impregnation, and Coating" reprocessing technologies, cov khoom siv graphite ua tiav qhov zoo tshaj plaws hauv kev ua tau zoo, muab kev ntseeg siab kawg rau koj qhov kev tsim khoom siab -.

Kev ntsuas kev ua haujlwm	Standard Untreated Graphite	Reprocessed Graphite	Core Processing Technology
Purity (Cov ntsiab lus impurity)	Cov ntsiab lus carbon feem ntau yog nyob ib ncig ntawm 98%. Cov khoom seem hlau zoo li hlau, sodium, thiab boron tuaj yeem ua rau cov khoom sib kis tau yooj yim.	Achieves ib tug heev purity ntawm99.999%los yog siab dua, nrog tag nrho cov impurities qis dua 5 ppm, ua tau raws li cov khoom siv hluav taws xob nruj me ntsis - qib yuav tsum tau ua.

FAQ

01.Dab tsi yog graphite reprocessing?

Graphite reprocessing yog hais txog kev ua haujlwm theem nrab ntawm kev tsim thawj graphite-xws li purification, impregnation, thiab txheej txheej. Nws kov yeej tej yam kev txwv lub cev los txhim kho purity, ceev, oxidation tsis kam, thiab txhua yam muaj zog rau huab muaj ib puag ncig.

02.Vim li cas tus qauv graphite yuav tsum tau ultra- kub purification?

Standard graphite feem ntau muaj cov kab hlau tsis huv, uas tuaj yeem ua rau tuag taus hauv kev tsim khoom. Los ntawm kev qhia purifying gases ntawm huab cua kub siab tshaj 2400 degree, cov impurities no yog kiag li vaporized thiab muab rho tawm, ua tau ib tug semiconductor - qib purity ntawm 99.999% los yog siab dua.
