Vim li cas CARBON cov ntaub ntawv yuav tsum tau impregnated, thiab dab tsi yog lub hom phiaj ntawm IMPREGNATION?

Cov khoom siv carbon yog cov khoom ntxeem tau. Tag nrho cov porosity ntawm cov khoom carbon yog 16% ~ 25%, thiab cov khoom ntawm graphite yog 25% ~ 32%. Lub hav zoov ntawm ntau qhov pores yuav ua rau muaj kev cuam tshuam tsis zoo rau lub cev thiab tshuaj lom neeg thiab kev ua haujlwm ntawm cov ntaub ntawv carbon. Piv txwv li, nrog qhov nce ntawm porosity, qhov ntom ntom ntawm cov khoom siv carbon tsawg zuj zus, qhov kev tiv thaiv nce ntxiv, lub zog ntawm lub zog txo qis, cov tshuaj lom neeg thiab corrosion kuj deteriorates, thiab permeability rau gases thiab kua nce. Yog li ntawd, rau qee qhov kev ua haujlwm siab ntawm cov khoom siv carbon thiab cov ntaub ntawv carbon, impregnation compaction yuav tsum tau ua.

Cov hom phiaj hauv qab no tuaj yeem ua tiav los ntawm kev kho impregnation thiab compaction:
(1) txo qhov porosity ntawm cov khoom;
(2) Txhim kho qhov ntom ntom ntawm cov khoom thiab txhim kho lub zog ntawm cov khoom:
(3) Txhim kho cov hluav taws xob thiab thermal conductivity ntawm cov khoom;
(4) Txo cov permeability ntawm cov khoom;
(5) Txhim kho oxidation kuj thiab corrosion kuj ntawm cov khoom;
(6) Kev siv cov roj nplaum impregnation tuaj yeem txhim kho qhov hnav tsis kam ntawm cov khoom.
Qhov tsis zoo ntawm impregnation thiab densification ntawm cov khoom carbon yog tias cov coefficient ntawm thermal expansion nce me ntsis.
