Peb paub tias peb tsuas vam meej yog tias peb tuaj yeem lav peb cov nqi sib tw ua ke thiab zoo tib lub sijhawm rau Cov Neeg Muag Khoom Sab Saum Toj Grey Black Silicon Carbide Sic Carborundum Tuam Tshoj High Purity, Peb txais tos cov neeg siv khoom tshiab thiab yav dhau los los ntawm txhua qhov chaw ntawm lub neej los tham nrog peb rau kev sib raug zoo yav tom ntej thiab tau txais kev ua tiav sib koom ua ke!
Peb paub tias peb tsuas vam meej yog tias peb tuaj yeem lav peb qhov kev sib tw ua ke ntawm tus nqi thiab qhov zoo tib lub sijhawm rauTuam Tshoj Txheej Khoom Siv, Titanium DioxidePeb lub tuam txhab ua raws li lub siab ntawm "kev tsim kho tshiab, kev sib haum xeeb, kev ua haujlwm ua pab pawg thiab kev sib koom, kev taug kev, kev vam meej". Muab sijhawm rau peb thiab peb yuav ua pov thawj peb lub peev xwm. Nrog koj txoj kev pab zoo, peb ntseeg tias peb tuaj yeem tsim lub neej yav tom ntej ci ntsa iab nrog koj ua ke.
Cov khoom sib xyaw ua los ntawm cov pa roj carbon / carbon(txij no mus hu ua "C / C lossis CFC”) yog ib hom khoom sib xyaw ua ke uas yog ua los ntawm carbon thiab txhawb nqa los ntawm carbon fiber thiab nws cov khoom (carbon fiber preform). Nws muaj ob qho tib si inertia ntawm carbon thiab lub zog siab ntawm carbon fiber. Nws muaj cov khoom siv kho tshuab zoo, tiv taus cua sov, tiv taus corrosion, txhuam damping thiab thermal thiab hluav taws xob conductivity yam ntxwv.
CVD-SiCtxheej muaj cov yam ntxwv ntawm cov qauv sib xws, cov khoom siv compact, kub tsis kam, oxidation tsis kam, siab purity, acid & alkali tsis kam thiab organic reagent, nrog cov khoom ruaj khov thiab tshuaj lom neeg.
Piv nrog cov ntaub ntawv graphite uas muaj cov khoom purity siab, graphite pib oxidize ntawm 400C, uas yuav ua rau poob cov hmoov vim yog oxidation, ua rau muaj kuab paug rau ib puag ncig rau cov khoom siv peripheral thiab cov chaw nqus tsev, thiab ua rau cov khoom tsis huv ntawm ib puag ncig uas muaj cov khoom purity siab nce ntxiv.
Txawm li cas los xij, SiC txheej tuaj yeem tswj tau lub cev thiab tshuaj lom neeg ruaj khov ntawm 1600 degrees, Nws yog dav siv hauv kev lag luam niaj hnub, tshwj xeeb tshaj yog hauv kev lag luam semiconductor.
Peb lub tuam txhab muab cov kev pabcuam txheej txheem SiC los ntawm CVD txoj kev rau ntawm qhov chaw ntawm graphite, ceramics thiab lwm yam khoom siv, yog li cov pa roj tshwj xeeb uas muaj cov pa roj carbon thiab silicon teb rau qhov kub siab kom tau txais cov khoom siv SiC ntshiab siab, cov khoom siv tso rau ntawm qhov chaw ntawm cov khoom siv coated, tsim cov txheej tiv thaiv SIC. Cov SIC tsim tau sib txuas ruaj khov rau lub hauv paus graphite, muab cov khoom tshwj xeeb rau lub hauv paus graphite, yog li ua rau qhov chaw ntawm graphite compact, tsis muaj porosity, tiv taus kub siab, tiv taus corrosion thiab tiv taus oxidation.
Cov yam ntxwv tseem ceeb:
1. Kev tiv thaiv oxidation kub siab:
qhov kev tiv thaiv oxidation tseem zoo heev thaum qhov kub siab txog 1600 C.
2. Kev huv siab: ua los ntawm cov tshuaj lom neeg ua pa hauv qab qhov kub siab chlorination.
3. Kev tiv thaiv kev yaig: kev nyuaj siab, qhov chaw me me, cov khoom me me.
4. Kev tiv thaiv corrosion: acid, alkali, ntsev thiab cov organic reagents.
