Hauv kev lag luam ceramic, EipponCell HPMC YB 6000 yog ua haujlwm nyob rau hauv kev tsim cov khoom siv hluav taws xob siv hluav taws xob ntxiv roj lim cov ntaub ntawv uas muaj qhov kub thiab txias.Qhov tshwj xeeb HPMC cov khoom no pab kom ua tiav qhov sib npaug ntawm lub zog thiab qhov porosity, thaum kawg txhim kho lub zog ntawm cov khoom siv lim thaum tswj xyuas kev pom zoo.
High-temperature lim cov ntaub ntawv ua haujlwm tseem ceeb rau kev siv roj pom zoo thiab tshem tawm plua plav hauv qhov chaw kub kub.Ob qhov high-density thiab low-density ceramics tuaj yeem siv los ua lim xov xwm.High-density ceramics feem ntau yog tsim los ntawm silicon carbide, alumina, los yog cordierite cov ntaub ntawv, thaum tsawg-density ceramics feem ntau muaj cov aluminosilicate fibers.Tsawg-density ceramic lim cov ntaub ntawv muaj cov yam ntxwv zoo xws li cov porosity siab, tsis pom kev ua haujlwm, thiab zoo tawg toughness.Txawm li cas los xij, vim yog cov qauv xoob ntawm cov fibers, lawv cov khoom siv dag zog yog qhov tsawg, ua rau muaj kev pheej hmoo ntawm lim cartridge puas.
Ntawm qhov tod tes, high-density ceramics nthuav tawm cov tshuab ua haujlwm siab, tab sis kuj raug kev txom nyem los ntawm kev pom kev ua haujlwm siab.Muaj ib qho kev txwv tsis pub muaj kev sib raug zoo ntawm porosity thiab lub zog hauv cov ntaub ntawv zoo li no.Tsis tas li ntawd, high-density ceramics muaj qhov sib nqus loj dua, uas ua rau nce ntau lawm, kev teeb tsa, thiab kev thauj mus los cuam tshuam nrog cov ntaub ntawv lim.
