Imiterere n'imikoreshereze y'ingenzi ya carbide ya silikoni ikoze mu buryo bwa reaction-sintered

Imiterere ya karubide ya silikoni ikoreshwa mu gukora ibintu bitandukanye n'ikoreshwa ry'ingenzi? Karubide ya silikoni ishobora kandi kwitwa karubide cyangwa umucanga udashya, ni ikintu kidakoreshwa mu bimera, kigabanyijemo karubide ya silikoni y'icyatsi kibisi na karubide y'umukara ya silikoni ebyiri. Ese uzi imiterere n'ikoreshwa ry'ingenzi rya karubide ya silikoni? Uyu munsi, turabagezaho imiterere n'ikoreshwa ry'ingenzi rya karubide ya silikoni.

Karubide ya silikoni ikora neza ni ugukoresha umucanga wa quartz, coke ya peteroli ikozwe muri calcium (cyangwa coking y'amakara), slag y'ibiti (umusaruro wa karubide ya silikoni y'icyatsi ugomba kongeramo umunyu w'ibiribwa) n'ibindi bikoresho fatizo, binyuze mu itanura rishyushya rikoresha amashanyarazi rishyushya ubushyuhe bwinshi.

Imiterere ya karubide ya silikoni ikoze mu buryo bwa reaction-sintered:

1. Uburyo bwo gutwara ubushyuhe n'uburyo bwo kwaguka k'ubushyuhe bwa silicon carbide. Nk'ubwoko bw'ibikoresho birwanya ubushyuhe, amatafari ya karuboni afite ubushobozi bwo kurwanya impanuka. Ibi bigaragarira cyane mu buryo bwayo bukomeye bwo gutwara ubushyuhe (uburyo bwo kohereza ubushyuhe) n'uburyo bwo kwaguka k'ubushyuhe buri hasi cyane.

2, uburyo silicon carbide ikora. Silicon carbide ni ibikoresho bya semiconductor, uburyo ikora butandukana bitewe n'ubwoko n'ingano y'imyanda yinjijwe muri crystallization, kandi ubushobozi bwo kuyirwanya buri hagati ya 10-2-1012Ω·cm. Muri byo, aluminiyumu, azote na boron bigira ingaruka zikomeye ku buryo silicon carbide ikora, kandi uburyo silicon carbide ikora burushaho kwiyongera cyane.

3. Ubudahangarwa bwa karubide ya silikoni. Ubudahangarwa bwa karubide ya silikoni burahinduka bitewe n'impinduka z'ubushyuhe, ariko mu rugero runaka rw'ubushyuhe kandi imiterere y'ubushyuhe bwa resistor y'icyuma irahinduka. Isano iri hagati y'ubudahangarwa n'ubushyuhe bwa karubide ya silikoni iragoye cyane. Ubudahangarwa bwa karubide ya silikoni ikoreshwa mu gukora ibintu buriyongera bitewe n'ubushyuhe buzamuka kugeza ku gaciro runaka, kandi ubwiyongere bw'ubushyuhe buragabanuka iyo ubushyuhe bwongeye kuzamuka.

Ikoreshwa rya karubide ya silikoni:

1, ibikoresho bidashira – bikoreshwa cyane cyane mu gukora inziga y'umucanga, inziga yo gusya, inziga y'amabuye, inziga yo gusya, ifu yo gusya n'ibicuruzwa bya fotovoltaic mu tunyangingo twa fotovoltaic, utunyangingo twa fotovoltaic n'ibice byayo gusya, gusya no gusiga irangi ku buso.

2, ibikoresho birwanya ubushyuhe bwinshi – bishobora gukoreshwa nk'ibikoresho bigabanya ubushyuhe n'ubukonje mu nganda, mu gukora ibikoresho bihoraho byakozwe mu itanura rishyushye cyane, ibice bihamye, nibindi.

3, ibumba rikora neza - ntabwo rishobora kugabanya ingano y'itanura gusa, ahubwo rinanongera ubwiza bw'ibicuruzwa by'inganda, rigabanye igihe cyo gukora, ni ibikoresho byiza bitaziguye byo gutwika ibumba rya ceramic, ibumba ritagira ubushyuhe bwinshi rihoraho, rigaragaza porcelain ikozwe mu buryo bwa sintered.

4, ibyuma bidasanzwe - ibigo by'ibyuma n'ibyuma, inganda zikora ibikoresho by'ibyuma, bifite akamaro runaka.

5, ikindi – gikoreshwa mu gukora irangi ry’imirasire ya infrared cyangwa icyuma cyumisha imirasire ya infrared ya silikoni.

Karubide ya silikoni kubera imiterere yayo yoroshye ya organic chemical, ingano yo kohereza ubushyuhe bwinshi, ingano ntoya yo kwaguka, ingano nziza yo kwaguka, uretse ibikoresho birwanya kwangirika, hari izindi ngaruka z'ingenzi, nko: hamwe n'uburyo bushya bwo gukoresha kole y'ifu ya silikoni mu gice cy'umubiri cya centrifugal impeller cyangwa cylinder, ishobora kunoza ingano yo kwangirika no kongera ubuzima bw'imikorere inshuro 1 kugeza kuri 2; Ikoreshwa mu gukora ibikoresho birwanya kwangirika ku rwego rwo hejuru, ingano nto, uburemere bworoheje n'imbaraga nyinshi, kurinda ibidukikije no kuzigama ingufu biragaragara. Karubide ya silikoni yo mu rwego rwo hasi (ifite hafi 85% SiC) ni igikoresho cyiza cyo gusukura, gishobora gukoreshwa mu kwihutisha umuvuduko wo gukora icyuma, kandi gifasha mu guhindura imiterere no kunoza ubwiza bw'icyuma. Byongeye kandi, karubide ya silikoni ikoreshwa kandi mu gukora ibikoresho byinshi bishyushya amashanyarazi bya silikoni molybdenum.
