Cov yam ntxwv ntawm cov phaj kev sib txhuam yog txiav txim siab los ntawm lub cev muaj zog ntawm cov khoom sib txhuam
Cov yam ntxwv ntawm cov phaj kev sib txhuam yog qhov pib txiav txim siab los ntawm lub cev lub cev ntawm cov khoom sib txhuam, thiab kev siv cov fillers hauv cov khoom sib txhuam yog ib qho laj thawj. Cov fillers sib txawv tuaj yeem siv tau kom tau txais cov khoom sib txawv.
Muaj ntau lub cev thiab txhua yam khoom ntawm kev sib txhuam cov khoom, xws li deg hardness, sib tsoo plua plav adhesion, ntom, suab nrov, dual hnav, compressibility, nthuav, sab hauv shear, kev co kuj, huab cua tsis kam, roj nqus, nqus dej, cuam tshuam lub zog, Elasticity Modulus, compressive zog, porosity, flexural zog thiab siab tshaj plaws strain, thiab lwm yam. Ntxiv nrog rau cov kev cai tseem ceeb rau cov khoom, qhov cuam tshuam rau kev ua tau zoo ntawm lwm yam yuav tsum tau xav txog nyob rau hauv lub formulation tsim ntawm cov khoom sib txhuam.
Piv txwv li, ib qho kev sib txhuam cov khoom uas yuav tsum tau tshwj xeeb zoo thermal conductivity yuav tsum tau siv ib tug muab tub lim nrog zoo thermal conductivity. Txhua yam khoom siv nrog cov thermal conductivity zoo tseem yog cov khoom siv hlau, thiab cov ntaub ntawv no muaj cov thermal conductivity zoo. Yog li ntawd, siv cov khoom siv hlau ua cov khoom ntim hauv cov ntaub ntawv sib txhuam tuaj yeem txhim kho cov thermal conductivity ntawm cov khoom; tsim ib qho chaw Rau kev sib txhuam cov khoom siv nrog qis hardness yuav tsum, ib tug muab tub lim nrog qis hardness xws li vermiculite yuav siv tau los ua kev sib txhuam cov khoom siv nrog deg hardness ua tau raws li qhov yuav tsum tau tsim. Yog tias cov khoom siv kev sib txhuam nrog qhov ntom ntom yog tsim, ces xaiv ib hom muab tub lim nrog qhov ntom ntom, thiaj li ua tiav lub hom phiaj ntawm qhov ntom ntom ntawm cov khoom sib txhuam.
Txawm li cas los xij, thaum tsim cov kev ua tau zoo ntawm ntau yam khoom siv nrog cov kev cai tshwj xeeb, peb yuav tsum kawm thiab ua tib zoo saib xyuas cov kev ua tau zoo ntawm cov khoom. Cov piv txwv no qhia tau hais tias cov qauv tsim yuav tsum raug xaiv kom raug thiab tsim nyog raws li cov kev cai sib txawv ntawm cov khoom siv sib txhuam thiab ntau yam kev ua tau zoo ntawm cov fillers. Tau kawg, kev xaiv cov fillers tsis yog ib yam nkaus xwb, thiab feem ntau nws yog ib qho tsim nyog los xaiv ntau hom fillers kom tau txais cov txiaj ntsig zoo tshaj plaws. Txhawm rau ua kom tau raws li qhov xav tau ntawm lub cev thiab kev ua haujlwm ntawm cov khoom siv kev sib txhuam, tsis yog tsuas yog siv ntau yam khoom tsim nyog, tab sis kuj tsim nyog cov txheej txheem, cov cuab yeej tsim nyog thiab kev ua haujlwm tsim nyog kuj tseem yog qhov tseem ceeb.
