covHollow iav microspheres muaj ntau yam siv, tab sis ib qho tseem ceeb tshaj plaws yog nyob rau hauv kev lag luam roj hmab los ua cov khoom xws li silicone roj hmab sealants. Qhov zoo tshaj plaws uas hollow iav microspheres muab yog nyob rau hauv cov nqe lus ntawm txo qhov hnyav uas tso cai rau kev yooj yim daim ntawv thov rau kev thauj mus los du. Peb cov iav microsphere muab cov rwb thaiv tsev txaus, ua haujlwm ntev, thiab ruaj khov uas tsis yog pab thauj mus los xwb tab sis lwm yam kev siv thiab.
Yuav siv li cas Nrog Roj Hmab?
Nyob rau hauv cov nqe lus ntawm kev tshawb fawb, nws yuav tsum to taub hais tias qhov luaj li cas ntawm ib tug particle, nws muaj peev xwm hais txog kev sib txuas lus, thiab lub load nws muaj nyob rau hauv kev txiav txim lub zog, kuj, thiab rigidity nyob rau hauv tej yam composites. Ntau qhov kev tshawb fawb tseem tuaj txog qhov xaus tias cov khoom hauv roj hmab tau txhim kho zoo thaum lub iav hollow iav microsphere tau muab tso rau hauv lawv. Cov kev tshawb fawb tseem qhia tau hais tias thaum ib yam dab tsi muaj viscosity uas tsis tshua muaj melting nyob rau hauv qhov zoo tshaj qhov uas yuav ua tau los ntawm kev siv hollow iav microspheres nyob rau hauv polyester thiab epoxy resins.
Hauv lwm txoj kev tshawb fawb, tus cwj pwm ntawmhollow iav microspheres tau kawm txog kev puas tsuaj thiab lub zog thaum muab tso rau hauv cov khoom sib xyaw xws li roj hmab. Lub hollow iav microspheres muaj zog ntau dua piv rau kev tsim cov khoom sib xyaw ntawm nws tus kheej. Tsis tas li ntawd, thaum muaj ntau hom kev sib xyaw tau npaj los ntawm hollow iav microspheres, qhov kev soj ntsuam tau ua kom lub zog ntawm cov khoom ua kom siab dua thaum lub hollow iav microsphere siab nyob rau hauv cov khoom siv thaum lub sij hawm koom ua ke. Tsis tas li ntawd, lub peev xwm rau kev nqus ntawm lub zog ntawm cov khoom tau nce mus txog 40% los ntawm kev siv hollow iav microsphere. Ib qho ntawm cov kev tshawb fawb tseem ceeb tshaj plaws yog hais txog qhov dielectric qhov ntawm lub hollow iav microspheres uas tau ntim nrog cov khoom sib hloov thiab hauv qhov no, nws tau pom tias qhov sib xws tau nce thiab poob qis hauv cov ntsiab lus ntawm dielectric thaum hollow iav microspheres tau ntxiv rau hauv. nce kom muaj nuj nqis. Tsis tas li ntawd nyob rau hauv cov ntsiab lus ntawm pob txha nyob rau hauv cov nqe lus ntawm hollow iav microsphere, nws tau muab sau tseg hais tias cov incorporation ntawm lub microspheres ua tau txhim khu lub flexural modulus thiab txo lub toughness thiab lub zog nyob rau hauv cov nqe lus ntawm tawg.
Lub hollow microsphere yog ib yam khoom tshwj xeeb heev uas kuj yog inorganic nyob rau hauv cov xwm thiab muaj ntau haiv neeg siv. Qhov txiaj ntsig zoo tshaj plaws ntawm lawv cov kab noj hniav hollow yog tias nws muab kev sib cais ntxiv nrog rau cov cua sov thiab muaj qhov ntom ntom ntom ntom. Yog li, nyob rau hauv cov nqe lus ntawm cov tswv yim siv nyob rau hauv kev lag luam roj hmab, ib qho tseem ceeb heev nam yog hais tias ntawm nws incorporated nyob rau hauv silicone roj hmab uas encompasses raws li ib tug muab tub lim tsis tsuas zoo spheres, tab sis kuj fractured sawv daws yuav nyob rau hauv cais ratios. Kev siv hauv kev lag luam roj hmab kuj qhia tau hais tias txawm tias thaum lub hollow iav microspheres tawg, nws theej nce cov khoom uas tau tham saum toj no.
