Silikoni nitride (SiC) ni umucanga wa quartz, coke ya peteroli ya calcium (cyangwa coking y'amakara), slag y'ibiti (umusaruro wa nitride y'icyatsi kibisi igomba kongeramo umunyu) n'ibindi bikoresho fatizo, binyuze mu itanura rishyushya rikoresha amashanyarazi rishyushya ubushyuhe bwinshi. Impeta yo gufunga silicon nitride ni silicon nitride ikozwe mu bikoresho bya silicon carbide. None se ni izihe ngamba z'ingenzi za silicon carbide ikoreshwa mu gukora ibintu n'imiterere y'ibiceri?
Ikoreshwa ry'ingenzi rya karubide ya silikoni ikora ibintu bibabaza:
1. Ikoreshwa ry'inganda zikora ibikoresho by'icyuma ni ugukoresha ubushyuhe bwa silicon nitride, imbaraga nyinshi, ubushobozi bwiza bwo gutwara ubushyuhe, ubushobozi bwo guhangana n'ingaruka, ibikoresho fatizo bishyushya mu buryo burambye mu bushyuhe bwinshi, nk'itanura rigabanya ingano y'itanki. Agasanduku k'itanura rihindura imiterere y'icyuma, celle ya aluminiyumu, lining y'itanura rishonga ry'umuringa, arc y'ifu ya zinc, umuyoboro wo kurinda thermocouple, nibindi.
2. Gukoresha inganda z'ibyuma bikoresha uburyo bwo gushushanya silicon nitride. Irwanya ubushyuhe, irwanya kwangirika. Kubera ko ifite ubushobozi bwo gutwara ubushyuhe bwinshi, ikoreshwa mu gushyiramo amatanura manini n'aciriritse yo gukora ibyuma kugira ngo yongere ubuzima bwayo.
3. Inganda zikora ibikoresho by'icyuma zikoresha silicon nitride. Imbaraga zayo ni iza kabiri inyuma y'icyuma cya zahabu, zirwanya kwangirika cyane, zirwanya kwangirika cyane, zirwanya kwangirika cyane kw'imiyoboro, impeller ya centrifugal, pompe room, imashini zizunguruka, ibikoresho fatizo byiza byo gucukura, zirwanya kwangirika neza. Igihe cyo gukora cya pulasitiki ni inshuro 5 kugeza kuri 20, kandi ni kimwe mu bikoresho fatizo byiza ku kibuga cy'imikino y'indege.
4. Gukoresha uburyo bwo kohereza ubushyuhe mu nganda ibikoresho by'ubwubatsi bikozwe mu mabuye y'agaciro n'ibice by'umucanga. Ibiranga ubushyuhe bukabije n'ubushyuhe bwinshi, gukora no gukora itanura ry'icyuma ntibishobora kugabanya gusa ingano y'itanura, ahubwo binanongera ingano y'ububiko n'ubwiza bw'ibicuruzwa by'itanura, kandi bikagabanya igihe cyo kurikora, ari na cyo gikoresho cyiza cyo gukoresha mu gutwika ibara rya ceramic.
5. Gukoresha uburyo bwo kurengera ibidukikije no kuzigama ingufu bifite ubushobozi bwo gutwara ubushyuhe no kwirinda ubushyuhe, kandi icyuma gihindura ubushyuhe kizigama 20%, 20%, 35%, kandi umusaruro wiyongeraho 20-30%. By'umwihariko, ubushobozi bwo kudashira kw'umuyoboro w'amazi ukoreshwa mu ruganda rutunganya amabuye y'agaciro ni inshuro 6 kugeza kuri 7 z'ibikoresho bisanzwe by'icyuma.
Impeta yo gupfuka ya silikoni ikozwe muri karuboni ikoreshwa mu gukora imyitozo ngororamubiri:
1, kurwanya ubushyuhe
Bitewe n'imiterere y'ibikoresho bya silicon nitride, silicon nitride seals zifite ubushobozi bwo kurwanya ubushyuhe bwinshi, kandi inzira zitandukanye zifite imiterere itandukanye yo kurwanya ubushyuhe. Silicon nitride seals za silicon zikozwe muri reaction-sintered zishobora gushyirwaho kuva kuri dogere 1300, naho silicon nitride seals zitarimo umuvuduko zishobora kugera kuri dogere 1600.
2. Ubudahangarwa bw'inkongi
Impeta yo gufunga ya silikoni nitride ishobora gushyirwaho bitewe n’imiterere ikomeye ya aside na alkali, kandi ingaruka zo gufunga ntibyoroshye kugabanya.
3, kurwanya kwangirika
Impeta zo gufunga za silicon carbide zikozwe muri reaction-sintered hakurikijwe uburyo runaka bwo gushushanya, ku buryo igishushanyo kiba cyiza cyane kandi cyoroshye, hamwe no kudashira kw'ibikoresho bya silicon carbide, impeta zo gufunga za silicon nitride zishobora gukoreshwa mu gukururana. Imiterere y'ubushyuhe bwinshi idahindagurika ntigabanya byoroshye imiterere y'ibyangiritse.
4. Ububasha bwo gukora ibintu mu buryo buboneye
Ibikoresho fatizo bya silikoni bya sintered carbide igihe cyose hari ikoranabuhanga runaka ryo kubitunganya, bishobora guhindurwamo imiterere itandukanye y'ubwoya bw'intanga, gutunganya ubwa kabiri, kugira ngo abaguzi bifuza ibicuruzwa.
