(Cov khoom SSICTsim los ntawmWintrustek)
Tej zaum qhov tseem ceeb tshaj plaws nyob rau hauv kev tsim cov ceramics yog sintering. Thaum lub sij hawm theem no, cov khoom siv raw mus dhau ib tus naj npawb ntawm cov tshuaj thiab lub cev hloov pauv raws li qhov kub-lub cev raug rho tawm haujlwm ntawm cov khoom siv melting ntawm cov hmoov av ceramic. Txawm hais tias muaj ntau yam kev sib txawv sintering, lawv txhua tus yeej siv tau cov yam ntxwv tib yam los tsim cov txiaj ntsig zoo nrog cov neeg xav tau thiab cov khoom siv uas xav tau.
Txoj kev sib sau thiab cov ntaub ntawv raw rau hauv kev sib xyaw ua ke, ze-net duab yog thawj kauj ruam hauv kev tsim cov khoom sib xyaw. Nias, casting, txhaj tshuaj moulding, lossis muab cov khoom noj khoom haus uas muaj cov hmoov nplej los ntawm ntsuab-machining-feem ntau yog qhov ua tiav. Txawm li cas los xij, tsuas yog sintering-uas tuaj yeem ua nrog lossis tsis tau thov nias-tuaj yeem ua tiav cov ceramic ntsuab-lub cev me me porous. Cov khoom siv ceramic tsim los ntawm kev luam tawm sintering muaj lub cev tsis tshua muaj zog vim tias qhov ceev tau tsa siab tshaj 95% ntawm theoretical density thaum kev tsim khoom.
Scilless sintering tsim nyog yuav luag ntomSilicon Carbide Khoomnrog cov neeg kho tshuab zoo dua qub. Cov txheej txheem no muaj cov txiaj ntsig ntawm kev tsim kho cov qauv ntawm cov khoom los tsim cov khoom nrog ntau yam duab, thiab kev siv cov khoom muaj txiaj ntsig zoo tuaj yeem ua rau muaj lub zog tshwj xeeb thiab lub zog. Raws li lub npe qhia, cov ntaub ntawv no tuaj yeem tsim tawm yam uas tsis muaj kev xav tau sab nraud siab.Alumina (al203)thiabBoron Carbide (B4C)yog cov piv txwv ntawm cov sintering additives uas muaj peev xwm tau siv thaum nias kom fuse sic hmoov rau hauv cov khoom sib luag nrog cov khoom sib luag zoo.
TussejCov ntaub ntawv tuaj yeem tsim los ntawm kev siv lub ntsej muag, uas tau hloov ultra-nplua, high-purity sic hmoov rau hauv cov khoom ceramics. Muaj ob txoj hauv kev rau ua qhov no:Khoom-Cheeb Tsam SinteringthiabUa kua-Phase Sintering:
Khoom-Phaj Sintering:Txoj kev no siv cov tshuaj kub tseem ua rau muaj cov yam ntxwv muaj peev xwm thiab cov yam ntxwv ntawm lub cev, tshwj xeeb yog lub zog thaum muaj ntau yam kev siv.
Kua-Pease Sintering:Hom kev sintering no cuam tshuam nrog kev sib ntxiv ntawm Sintering AIDS hauv cov nyiaj me me, thiab theem cuam tshuam interranular yuav khaws cov oxides tseem ceeb tom qab sintering. Raws li qhov tshwm sim, ua kua-theem sintered sintered sic muaj lub zog siab thiab nyiam tawg kom tawg raws cov ciaj ciam av. Cov theem ua kua uas cov khoom thaum lub sijhawm soined zoo ua rau cov sintering kub hauv kev sib piv rau cov khoom-theem Sintering.
Cov lus Cermics uas yog cov khoom siv hluav taws xob ua haujlwm-theem seetered nthuav tawm cov acids muaj zog thiab cov hauv paus zoo li cov neeg kho tshuab txhim kho ntawm cov khoom siv kub siab.
Khoom:
Txhua yam suav, zoo duaTussejCov ntaub ntawv nrog ntau dua kev coj dawb huv thiab tuab yog tsim los ntawm kev ntsuas cov duab ntawm silicon carmide. Qhov no qhia tau hais tias nws tuaj yeem siv rau cov ntawv thov uas xav tau cov khoom siv hluav taws xob kom zoo xws li tsim cov khoom siv hluav taws xob kub.
Wintrustek kuj tsim tawm ntauCov khoom SSICnyiamSsic bushing, SSIC NCEJ, SSIC NOzzle......, peb txhawb kev kho rau cov duab sib txawv.
