Uburyo bwo gukora carbide ya silikoni ikora neza

Karubide ya silikoni ikoze mu buryo bwa reaction-sintered ni igikoresho cy'ingenzi gishyuha cyane, gifite imbaraga nyinshi, ubukana bwinshi, kidapfa kwangirika cyane, kidapfa kwangirika cyane kandi kidapfa kwangirika cyane hamwe n'indi miterere myiza, gikoreshwa cyane mu mashini, mu kirere, mu nganda za shimi, mu ngufu n'ahandi.

 

1. Gutegura ibikoresho fatizo

Gutegura ibikoresho fatizo bya silikoni bihindura umwuka ni ifu ya karuboni na silikoni, aho karuboni ishobora gukoreshwamo ibintu bitandukanye birimo karuboni, nka coal coaster, grafiti, amakara, nibindi., ifu ya silikoni ikunze gutoranywa ifite ingano y'uduce twa silikoni ifite ubuziranenge bwa 1-5μm. Ubwa mbere, ifu ya karuboni na silikoni bivangwa mu rugero runaka, bongeramo ingano ikwiye y'ibifunga n'ibijyana n'amazi, hanyuma bakavanga neza. Hanyuma uruvange rushyirwa mu cyuma gisya umupira kugira ngo ukomeze kuvanga no gusya kugeza igihe ingano y'uduce iri munsi ya 1μm.

2. Uburyo bwo kubumba

Uburyo bwo gushushanya ni imwe mu ntambwe z'ingenzi mu gukora karubide ya silikoni. Uburyo bukunze gukoreshwa mu gushushanya ni ugukanda, gukata no gukata. Gukaranga bivuze ko uruvange rushyirwa mu ibumba rugakoranwa n'igitutu cya mekanike. Gukata bivuze kuvanga uruvange n'amazi cyangwa organic solvent, ukarushyira mu ibumba ukoresheje syringe mu buryo bwo gukata, hanyuma ugashyiraho umusaruro urangiye nyuma yo guhagarara. Gukata umuvuduko uhoraho bivuga uruvange mu ibumba, munsi y'uburinzi bw'ibumba cyangwa ikirere cyo gukata umuvuduko uhoraho, akenshi ku gitutu cya 20-30MPa.

3. Uburyo bwo gukaraba

Gutunganya ibintu bishya ni intambwe y'ingenzi mu gukora carbide ya silikoni ivanze n'ingufu. Ubushyuhe bwo gutwika, igihe cyo gutwika, ikirere cyo gutwika n'ibindi bintu bigira ingaruka ku mikorere ya carbide ya silikoni ivanze n'ingufu. Muri rusange, ubushyuhe bwo gutwika bwa carbide ya silikoni ivanze n'ingufu bushobora kuba hagati ya 2000-2400℃, igihe cyo gutwika muri rusange ni amasaha 1-3, kandi ikirere cyo gutwika muri rusange kiba kidakora, nka argon, azote, n'ibindi. Mu gihe cyo gutwika, uruvange ruzahura n'ingaruka za shimi kugira ngo rukore kristu za silikoni. Muri icyo gihe, karuboni izahura kandi n'imyuka iri mu kirere kugira ngo ikore imyuka nka CO2 na CO2, ibi bigira ingaruka ku bucucike n'imiterere ya silikoni. Kubwibyo, kubungabunga ikirere gikwiye cyo gutwika n'igihe cyo gutwika ni ingenzi cyane mu gukora carbide ya silikoni ivanze n'ingufu.

4. Uburyo bwo kuvurwa nyuma yo kuvurwa

Karubide ya silikoni ikoze mu buryo bwa reaction-sintered ikenera inzira yo gusukura nyuma yo kuyitunganya. Inzira zisanzwe zo gusukura nyuma yo kuyitunganya ni ugutunganya, gusya, gusiga, gusiga n'ibindi. Izi nzira zigamije kunoza ubwiza n'ubuziranenge bwa karubide ya silikoni ikoze mu buryo bwa reaction-sintered. Muri zo, inzira yo gusya no gusiga ni uburyo busanzwe bwo kuyitunganya, bushobora kunoza kurangiza no kugorora ubuso bwa karubide ya silikoni. Uburyo bwo gusiga oxidation bushobora gukora urwego rwa oxidation kugira ngo bwongere ubushobozi bwo kudasiga oxidation no kudahinduka kwa shimi bya karubide ya silikoni ikoze mu buryo bwa reaction-sintered.

Muri make, gukora karubide ya silikoni ikora ibintu bishya ni inzira igoye, ikeneye ubuhanga mu ikoranabuhanga n'imikorere itandukanye, harimo gutegura ibikoresho fatizo, gutunganya, gutunganya ibintu bishya n'imikorere nyuma yo kuvurwa. Ni mu gusobanukirwa neza ubu buryo n'imikorere, ibikoresho bya silikoni bifite ireme ryo hejuru bishobora gukorwa kugira ngo bihuze n'ibikenewe mu nzego zitandukanye zikoreshwa.
