Ibyiza nuburyo bukoreshwa bwa reaction-yacuzwe na silicon karbide

Imyitwarire-ya silicon karbide yibintu nibikoreshwa nyamukuru? Carbide ya silicon irashobora kandi kwitwa carborundum cyangwa umucanga utagira umuriro, ni uruganda rudasanzwe, rugabanijwemo karbide yicyatsi kibisi na karubone yumukara wa kabiri. Waba uzi imiterere nuburyo bukoreshwa bwa silicon karbide? Uyu munsi, tuzamenyekanisha imiterere nuburyo bukoreshwa bwa karubide ya silicon.

Carbide ikora neza ya silicon ni ugukoresha umucanga wa quartz, kokiya ya peteroli ibarwa (cyangwa amakara yamakara), ibiti byimbaho ​​(umusaruro wa karbide yicyatsi kibisi ugomba kongeramo umunyu wibiryo) nibindi bikoresho fatizo, ukoresheje itanura rishyushya amashanyarazi bikomeza gushonga ubushyuhe bwinshi.

Ibyiza bya reaction ya-silicon karbide:

1. Ubushyuhe bwumuriro hamwe na coefficente yo kwagura ubushyuhe bwa karubide ya silicon. Nkubwoko bwibikoresho byangiritse, amatafari ya karubone afite imbaraga zo guhangana no guhungabana. Ibi bigaragarira cyane cyane mumashanyarazi akomeye (coefficente de transfert) hamwe na coefficient nkeya yo kwagura ubushyuhe.

2, ubwikorezi bwa silicon karbide. Carbide ya silicon ni ibikoresho bya semiconductor, uburyo bwayo buratandukana nubwoko nubwinshi bwumwanda winjiye muri kristu, kandi kurwanya biri hagati ya cm 10-2-1012Ω · cm. Muri byo, aluminium, azote na boron bigira uruhare runini ku mikorere ya karubide ya silicon, kandi na karubide ya silicon hamwe na aluminiyumu yiyongera cyane.

3. Kurwanya karubide ya silicon. Kurwanya karibide ya silicon ihinduka hamwe nubushyuhe bwubushyuhe, ariko mubipimo byubushyuhe runaka hamwe nubushyuhe buranga ibyuma birwanya ibyuma birahindurwa. Isano iri hagati yo guhangana nubushyuhe bwa karubide ya silicon iraruhije. Ubworoherane bwa reaction ya-silicon karbide yiyongera hamwe nubushyuhe buzamuka bugera ku gaciro runaka, kandi ubushyuhe bugabanuka iyo ubushyuhe bwongeye kuzamuka.

Gukoresha karibide ya silicon:

1, ibikoresho birwanya kwambara - cyane cyane bikoreshwa mugukora uruziga rwumucanga, gusya sandpaper, whetstone, gusya uruziga, gusya paste nibicuruzwa bifotora mumashanyarazi ya selile, selile yifoto hamwe nibice byo gusya, gusya no gusya.

2, ibikoresho byohejuru-byohejuru - birashobora gukoreshwa nkinganda ya metallurgical deoxidizer hamwe nibikoresho birwanya ruswa, kugirango ikore itanura ryubushyuhe bwo hejuru itanura ibice, ibice byagenwe, nibindi.

3, ububumbyi bukora - ntibushobora kugabanya ubwinshi bw itanura, ariko kandi binazamura ubwiza bwibicuruzwa bitanura mu nganda, kugabanya igihe cyizunguruka, nigikoresho cyiza kitaziguye cyo gucumura ceramic glaze, guhorana ubushyuhe bukabije butari oxyde ceramique, byerekana feri ya feri.

4, ibyuma bidasanzwe - inganda zicyuma nicyuma, inganda zikora inganda, zifite gahunda runaka.

5, ibindi - bikoreshwa mugukora imirasire yimirasire ya kure cyangwa silicon karbide isahani yumuriro wa kure.

Carbide ya silicon kubera imiterere ya chimique yoroshye, coefficente yohereza ubushyuhe bwinshi, coefficente yo kwagura umurongo muto, kwihanganira kwambara neza, usibye kwambara ibikoresho birwanya, hari nibindi bintu byingenzi bikoreshwa, nka: hamwe nuburyo bushya bwo gufata ifu ya karubide ya silicon karike centrifugal impeller cyangwa silindiri yumubiri, irashobora kunoza imyambarire no kongera ubuzima bwa serivisi inshuro 1 kugeza kuri 2; Byakoreshejwe mugukora ibikoresho byo murwego rwohejuru, guhangana nubushyuhe bwo hejuru, ubunini buto, uburemere bworoshye nimbaraga nyinshi, kurengera ibidukikije ningaruka zo kuzigama ingufu biragaragara. Carbide yo mu rwego rwo hasi (irimo 85% SiC) nigikoresho cyiza cyo kwangiza, gishobora gukoreshwa mu kwihutisha igipimo cy’ibyuma, kandi kikaba gifasha gukoresha ibihimbano no kuzamura ubwiza bwibyuma. Mubyongeyeho, karbide ya silicon nayo ikoreshwa mugukora ibikoresho byinshi byo gushyushya amashanyarazi silicon molybdenum inkoni.
