Ikoreshwa ryingenzi rya reaction ya-silicon karbide nibiranga impeta

Nitride ya Silicon (SiC) ni umucanga wa quartz, ibarwa ya peteroli ya kokiya (cyangwa amakara yamakara), ibiti byimbaho ​​(umusaruro wa nitride wicyatsi kibisi ugomba kongeramo umunyu) nibindi bikoresho fatizo, binyuze mumatara ashyushya amashanyarazi bikomeza ubushyuhe bwo hejuru. Impeta ya nitride ya silicon nigicuruzwa cya silicon nitride ikozwe mubintu bya karubide ya silicon. Nibihe bintu byingenzi byokoresha reaction ya-silicon karbide nibiranga kashe?

Ikoreshwa ryingenzi rya reaction sintering silicon karbide:

. Inzira yo gukosora itanura, selile ya electrolytike ya aluminium, itanura ry'umuringa ushonga, ifu ya zinc ifuru arc, umuyoboro urinda thermocouple, nibindi.

2. Gukoresha inganda zibyuma zikoresha etrike ya nitride ya silicon. Kurwanya ubushyuhe, kurwanya abrasion. Kubera ubushyuhe bwiza bwumuriro, bikoreshwa mugutondekanya itanura rinini kandi rinini rikozwe mu byuma kugirango bongere ubuzima bwa serivisi.

3. Inganda zikora inganda za metallurgjiya zikoresha ingufu za nitride ya silicon ni iya kabiri gusa mu byuma bya zahabu, birwanya kwambara gukomeye, ni ukurwanya kwambara gukomeye, kwangirika kwinshi kw’umuyoboro, imashini itwara abantu, icyumba cya pompe, imashini zizunguruka, gucukura amabuye y'agaciro meza, kwambara neza. Ubuzima bwa serivisi ya plastike ni inshuro 5 kugeza kuri 20, kandi nikimwe mubikoresho byiza bibera mumikino yimikino yindege.

4. Ibiranga ubushyuhe bukabije hamwe nubushyuhe bukabije bwumuriro, kubyara no gukora itanura ryicyuma ntigishobora kugabanya gusa itanura, ahubwo rishobora no kuzamura ububiko bwububiko nubwiza bwibicuruzwa by itanura, kandi bikagabanya igihe cyo gukora, aribwo buryo butaziguye ibikoresho byo kurasa pigment ceramic.

5. Gushyira mu bikorwa kurengera ibidukikije no kuzigama ingufu bifite ubushyuhe bwiza bwo guhangana n’ubushyuhe, hamwe n’ubushyuhe bwo kuzigama ubushyuhe bizigama 20%, gukoresha lisansi 20%, gukoresha lisansi 35%, kandi umusaruro wiyongereyeho 20-30%. By'umwihariko, kwihanganira kwambara umuyoboro w'amazi usohoka ukoreshwa mu ruganda rutunganya ubucukuzi bw'amabuye y'agaciro wikubye inshuro 6 kugeza kuri 7 z'ibyuma bisanzwe.

Ibicuruzwa-byahinduwe na silicon karbide kashe yerekana impeta:

1, kurwanya ubushyuhe

Kubera ibiranga ibikoresho bya nitride ya silicon, kashe ya nitride ya silicon ifite ubushyuhe bwinshi, kandi inzira zitandukanye zifite ubwoko butandukanye bwo kurwanya ubushyuhe. Ikirangantego cya silicon nitride kashe irashobora gukoreshwa kuva kuri dogere 1300, kandi kashe ya nitride ya silicon idafite ingufu irashobora kugera kuri dogere 1600.

2. Kurwanya ruswa

Impeta ya silicon nitride irashobora gukoreshwa uhereye kuri acide ikomeye na alkali, kandi ingaruka zo gufunga ntabwo byoroshye kugabanya.

3, kwambara

Ikirangantego cya silicon karbide kashe yerekana impeta ukurikije inzira runaka yikarita, kugirango gahunda isobanutse neza kandi yoroshye, iherekejwe no kwambara ibikoresho bya karubide ya silikoni, impeta ya nitride ya silikoni irashobora gukoreshwa kugirango ikoreshwe. Gukomeza ubushyuhe bwo hejuru ntibishobora kugabanya ibyangiritse.

4. Guhindagurika

Imyitozo ngororamubiri ya silicon karbide ibikoresho fatizo mugihe cyose hari tekinoroji yo gutunganya, irashobora guhindurwa muburyo butandukanye bwo gusama ubwoya, gutunganya kabiri, kugirango abakiriya bashaka ibicuruzwa.
