Hom Reaction Bonded Silicone Carbide (RBSiC / SiSiC)

Hom Kev Tiv ThaivBonded Silicone Carbide (RBSiC / SiSiC)

Tam sim no, muaj ntau qhov chaw tsim khoom los muab cov khoom lag luam Reaction Bonded SIC rau cov kev lag luam sib txawv. Shandong Zhongpeng Tshwj Xeeb Ceramics Co., Ltd yuav tsum yog ib qho ntawm cov khoom lag luam zoo tshaj plaws nrog ntau hom Reaction Bonded SIC cov khoom, xws li Nozzle thiab lwm yam hauv cov hluav taws xob fais fab, ceramics, kiln, hlau thiab hlau, mine, thee, alumina, roj av, tshuaj lom neeg. , ntub dej desulphurization, machinery manufacturing, thiab lwm yam tshwj xeeb industries nyob rau hauv lub ntiaj teb no.

Lub Reaction Bonded SIC tuaj yeem muab faib uacov tshuaj tiv thaiv-bonded silicon carbidethiabcov tshuaj tiv thaiv-ua silicon carbide, raws li seb qhov pib dawb paug muaj silicon carbide hais.

Reaction-bonded silicon carbide

Reaction-bonded silicon carbide hais txog cov txheej txheem los tsim cov silicon carbide composite. Nws yog nyob rau hauv qhov teeb meem uas pib dawb paug muaj silicon carbide hmoov. Hauv cov txheej txheem tshuaj tiv thaiv, cov pa roj carbon thiab silicon hnov ​​​​mob los tsim cov theem tshiab silicon carbide thiab ua ke nrog thawj silicon carbide. Cov txheej txheem kev npaj yog raws li hauv qab no, uas yog ib qho kev siv feem ntau:

Sib tov silicon carbide hmoov, carbon hmoov thiab organic binder;

Sib tov qhuav thiab debonded;

Thaum kawg, tau txais cov tshuaj tiv thaiv-bonded silicon carbide los ntawm silicon infiltration.

Cov tshuaj tiv thaiv-bonded silicon carbide uas ua los ntawm txoj kev no feem ntau muaj coarse silicon carbide crystal nplej thiab cov ntsiab lus siab ntawm silicon dawb. Txawm li cas los xij, txoj kev no muaj cov txheej txheem yooj yim thiab tus nqi qis. Tam sim no,

Cov tshuaj tiv thaiv-ua silicon carbide

Qhov pib dawb paug ntawm cov tshuaj tiv thaiv-tsim silicon carbide tsuas muaj carbide. Qhov pib dawb paug ntawm cov pa roj carbon monoxide yog reacted nrog silicon lossis silicon alloy los npaj silicon carbide cov khoom sib xyaw. Cov txheej txheem no yog thawj zaug tsim los ntawm Hucke. Txoj kev Hucke kuj muaj nws qhov tsis zoo. Nws txoj kev npaj yog qhov nyuaj dua. Tus nqi ntawm txoj kev no yog siab dua. Nyob rau tib lub sijhawm, ntau cov pa roj hloov pauv thaum lub sijhawm thermal tawg. Qhov no yuav ua rau kom yooj yim tawg ntawm Tuam Tshoj. Yog li ntawd, txoj kev no yog qhov nyuaj dua los tsim cov khoom loj.

Tsis tas li ntawd, roj av coke yog siv los ua raw khoom los npaj tag nrho cov pa roj carbon slabs, thiab ces silicon carbide yog tsim. Txawm li cas los xij, cov khoom ntawm cov ntaub ntawv uas tau npaj muaj kuj tsawg. Nws lub zog yog feem ntau qis dua 400mpa. Lub uniformity ntawm cov tau txais silicon carbide tsis zoo. Vim tias tus nqi qis ntawm roj av coke, tus nqi ntawm txoj kev no yog qhov tsawg.

Sua ummary

Piv nrog rau lwm txoj kev npaj ntawm silicon carbide ceramics, cov tshuaj tiv thaiv kev sib raug zoo muaj nws qhov tshwj xeeb zoo. Tam sim no, kev tshawb fawb hauv cheeb tsam no feem ntau tsom rau kev kawm txog cov txheej txheem sintering thiab cov yam ntxwv ntawm cov qauv thiab cov khoom ntawm cov khoom. Txawm li cas los xij, kev tshawb fawb txog kev ua tsis tiav yog qhov tsawg. Txawm hais tias muaj ntau cov kev tshawb fawb txog cov tshuaj tiv thaiv mechanism ntawm lawv, muaj ob peb txoj kev tshawb fawb ntawm permeability kinetics, cov tshuaj tiv thaiv mechanism thiab cov muaj pes tsawg leeg ntawm cov khoom theem ntawm cov txheej txheem alloying. Muaj ob peb txoj kev tshawb fawb txog kev npaj cov ntaub ntawv nrog cov khoom tswj tau thiab cov qauv los ntawm kev sib xyaw ntawm silicon infiltration thiab lwm yam ntaub ntawv. Cov yam no tseem yuav tsum tau kawm.
