Ibyiza bya grafite

Ibyiza bya grafite

1. Imiti ihamye
Graphite ni ibikoresho bya shimi bihamye, kandi imiti ihamye ntabwo iri munsi yicyuma cyagaciro. Gukemura kwayo muri feza yashongeshejwe ni 0.001% - 0.002%.Igishushanyontigishobora gukemuka mumashanyarazi cyangwa organic organique. Ntabwo ishobora kwangirika no gushonga muri acide nyinshi, shingiro n'umunyu.
2. Ubushyuhe bwo hejuru bwo guhangana na grafite
Binyuze mu bushakashatsi, ubushyuhe bwa serivisi ya rusange ya karubone irashobora kugera kuri 350 ℃; Ibyuma bya grafite nabyo ni 350 ℃; Icyiciro cya electrochemic grafite icyiciro gishobora kugera kuri 450-500 ℃ (munsi yumutwaro woroheje), imiterere yumubiri nubukanishi ntigihinduka, kandi ubushyuhe bwa serivisi burashobora kugera kuri 1000 ℃ munsi yumuyaga cyangwa ikirere kirinda.
3. Imikorere myiza yo kwisiga
Igishushanyoifite imikorere myiza yo kwisiga kubwimpamvu ebyiri. Imwe mu mpamvu zibitera nuko atome ya karubone iri muri latite ya grafite itunganijwe kuri buri ndege muburyo busanzwe bwa mpande esheshatu. Intera iri hagati ya atome irihafi, ni 0.142 nm, mugihe intera iri hagati yindege ari 0.335 nm, kandi iratandukana hagati yicyerekezo kimwe. Indege ya gatatu isubiramo umwanya windege yambere, indege ya kane isubiramo umwanya windege ya kabiri, nibindi. Muri buri ndege, imbaraga zihuza hagati ya atome ya karubone zirakomeye cyane, mugihe intera iri hagati yindege ari nini, kandi imbaraga za van der Waals hagati yazo ni ntege nke cyane, kuburyo byoroshye kugenda no kunyerera hagati yabyo, niyo mpamvu yibanze. kuki ibikoresho bya grafite bifite amavuta yo kwisiga.
Impamvu ya kabiri ni uko ibikoresho bya grafite bifatanye cyane nibikoresho byinshi byicyuma, bityo grafite ya exfoliated irashobora kwizirika byoroshye hejuru yicyuma mugihe cyo gusya hamwe nicyuma, bigakora urwego rwafirime.
4. Ibindi bintu biranga grafite
Ugereranije nibindi bikoresho,ibishushanyo mboneraufite kandi ubushyuhe bwinshi bwo hejuru, coefficient nkeya yo kwaguka kumurongo, gukonjesha byihuse no kurwanya ubushyuhe nibindi.
