Sintered hlau lim yog qhov kev xaiv zoo tshaj plaws rau cov txheej txheem pom cov ntawv thov uas xav tau lub zog siab thiab zoo heev tiv thaiv corrosion thiab kub. Cov ntxaij lim dej no yog tsim los ntawm cov hmoov hlau tsis muaj qhov sib ntxiv ntawm cov binders. Lawv yog tsim los ntawm isostatic nias thiab high-temperature nqus sintering. Qhov loj thiab kev faib tawm ntawm qhov pores tuaj yeem tswj tau los ntawm kev xaiv cov hmoov hlau.
Isostatic nias yog dab tsi?
Isostatic nias yog txheej txheem tsim khoom siv los tsim cov ntaub ntawv rau hauv cov duab uas xav tau los ntawm kev siv lub zog sib npaug ntawm txhua qhov kev qhia. Cov txheej txheem yuav muab cov hmoov los yog ib feem ua ntej rau hauv cov pwm uas raug kev kub siab los ntawm cov kua dej, feem ntau yog dej los yog roj. Lub siab yog siv uniformly nyob rau hauv tag nrho cov kev taw qhia, uas ua rau ib feem nrog uniform ceev thiab mechanical zog.
Pwm yog dab tsi?
Pwm yog hais txog cov txheej txheem tsim khoom uas cov khoom siv, xws li yas, roj hmab, lossis hlau, yog zoo li tus neeg xav tau los ntawm kev nias los yog nchuav rau hauv pwm. Cov pwm feem ntau yog ua los ntawm cov khoom siv tawv, ruaj khov, xws li hlau lossis txhuas, thiab tsim kom muaj cov duab zoo ib yam li cov khoom tiav.
Dab tsi yog sintering?
Sintering yog txheej txheem ntawm compacting thiab tsim cov khoom siv hluav taws xob thiab siab yam tsis muaj melting nws mus rau qhov chaw liquefaction. Cov txheej txheem feem ntau yog siv los tsim cov khoom siv los ntawm cov hmoov los yog lwm cov ntaub ntawv ntawm cov khoom me me, xws li hmoov hlau, ceramics, lossis polymers.
Nyob rau hauv sintering, cov khoom yog thawj zaug compressed rau hauv ib tug tshwj xeeb zoo los yog daim ntawv uas siv ib tug tuag los yog pwm. Cov khoom siv compacted ces rhuab mus rau qhov kub uas qis dua nws qhov melting point, ua rau cov khoom sib txuas ua ke los ntawm cov txheej txheem hu ua diffusion. Thaum tshav kub kub thiab siab siv thaum lub sij hawm sintering ua rau cov khoom sib txuas ua ke thiab tsim cov khoom ntom ntom.
