Ubushyuhe bwo hejuru hamwe na ruswa irwanya ruswa, silika grafite ikomeye ni nziza cyane gushonga ibyuma

Ibisobanuro bigufi:

Ningbo VET Energy Technology Co., Ltd. ni uruganda rukora tekinoroji rwashinzwe mu Bushinwa.Turi abahanga babigize umwuga kandi batanga ibicuruzwa bya Graphite silicide.

Ibicuruzwa

Siliconized grafite ni ibintu byinshi birimo karibide ya silicon ifatanye hejuru yubutaka bwa grafite.Ifite ibiranga ubukana bwinshi, imbaraga za mashini nyinshi no kwambara birwanya karibide ya silicon, hamwe nuburyo bwo kwisiga hamwe no guhangana nubushyuhe bwa grafite.Nibikoresho byiza byo guteranya hamwe nibikoresho bya kashe ya mashini, bikwiranye no gufunga imashini za pompe zitandukanye zamazi, pompe yamavuta, pompe yimiti, hamwe na pompe zitandukanye zihuta kandi ziremereye cyane.Byongeye kandi, siliconize grafite ifite imbaraga zo kurwanya okiside, kurwanya ubushyuhe bwumuriro, ubukana buke, hamwe n’amashanyarazi amwe, kandi irashobora gukoreshwa nkibikoresho nkibikoresho byo gushonga ibyuma hamwe nigituba.

Igishushanyo cya Siliconize (1)

Ibigize siliconizeigishushanyo ni kimwe, ubuso burahuza imbere, kandi igipimo cyibigize karibide ya silicon na grafite birashobora guhinduka.Iyo ibintu byinshi biri muri karubide ya silicon, niko ubwinshi bwibintu bigenda byiyongera, niko imbaraga zo guhonyora, hamwe no kurwanya biriyongera.
