Cov iav microspheres hollow muaj ntau yam kev 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 kev txo qhov hnyav uas tso cai rau kev siv yooj yim rau kev thauj mus los du. Peb lub iav microsphere muab kev rwb thaiv tsev txaus, durability, thiab ruaj khov uas tsis yog tsuas yog pab kev thauj mus los tab sis lwm yam kev siv thiab.
Yuav siv nrog roj hmab li cas?
Hais txog kev tshawb fawb, yuav tsum nkag siab tias qhov loj ntawm ib qho khoom me me, nws lub peev xwm hais txog kev sib txuas, thiab lub nra hnyav uas nws muaj hauv kev txiav txim siab lub zog, kev tiv taus, thiab kev nruj hauv qee cov khoom sib xyaw. Ntau qhov kev tshawb fawb kuj tau xaus lus tias cov khoom hauv roj hmab tau txhim kho ntau thaum cov iav microsphere hollow tau koom nrog hauv lawv. Kev tshawb fawb kuj qhia tias thaum qee yam muaj viscosity uas yog qis yaj hauv xwm dua li qhov ntawd tuaj yeem ua los ntawm kev siv cov iav microspheres hollow hauv polyester thiab epoxy resins.
Hauv lwm txoj kev tshawb nrhiav, tus cwj pwm ntawm cov iav hollow microspheres tau kawm txog kev tawg thiab lub zog thaum muab tso rau hauv cov khoom sib xyaw xws li roj hmab. Cov iav microspheres hollow muaj zog ntau dua piv rau kev tsim cov khoom sib xyaw ywj pheej. Ntxiv mus, thaum ntau yam khoom sib xyaw tau npaj los ntawm cov iav microspheres hollow, qhov kev soj ntsuam tau ua rau pom tias qhov ruaj khov ntawm cov khoom siv ua siab dua thaum cov iav microsphere hollow muaj qhov ceev ceev hauv cov khoom siv thaum lub sijhawm sib xyaw. Tsis tas li ntawd, lub peev xwm rau kev nqus lub zog ntawm cov khoom siv nce mus txog li 40% los ntawm kev siv cov iav microsphere hollow. Ib qho ntawm cov kev tshawb fawb tseem ceeb tshaj plaws yog hais txog qhov xwm txheej dielectric ntawm cov iav microspheres hollow uas tau sau nrog cov khoom sib xyaw hloov pauv thiab hauv qhov no, nws tau sau tseg tias qhov sib xws nce thiab kev poob qis hauv cov nqe lus ntawm dielectric thaum cov iav microspheres hollow tau ntxiv rau hauv qhov ntau ntxiv. Ntxiv mus, hauv cov ntsiab lus ntawm kev tawg hauv cov iav microsphere hollow, nws tau sau tseg tias kev koom ua ke ntawm cov microspheres tau txhim kho cov flexural modulus thiab txo qhov tawv thiab lub zog hauv cov nqe lus ntawm kev tawg.
Lub microsphere hollow yog ib yam khoom tshwj xeeb heev uas kuj tsis muaj organic thiab muaj ntau yam kev siv. Qhov txiaj ntsig tshwj xeeb tshaj plaws ntawm lawv lub qhov hollow yog tias nws muab kev sib cais ntxiv nrog rau kev kub thiab muaj qhov ceev ceev heev. Yog li, hais txog kev siv ua haujlwm hauv kev lag luam roj hmab, ib qho tseem ceeb heev yog tias nws koom nrog hauv cov roj hmab silicone uas suav nrog ua ib qho khoom ntim tsis yog tsuas yog cov pob zeb uas tsis muaj qhov tsis zoo, tab sis kuj tseem tawg hauv cov sib cais. Kev siv hauv kev lag luam roj hmab kuj qhia tau tias txawm tias thaum cov iav microspheres hollow tawg, nws ua rau cov khoom no ntau ntxiv uas tau tham saum toj no.
