Hollow microspheres cenospheres rau high-temperature sealants thiab adhesives
Cenospheres tuaj yeem ua si ntau lub luag haujlwm hauv qhov kub thiab txias sealants thiab adhesives. Cenospheres yog lub teeb yuag, hollow spheres muaj feem ntau ntawm silica thiab alumina, uas feem ntau tau txais los ntawm cov khoom siv hluav taws xob hauv cov hluav taws xob hluav taws xob. Thaum muab tso rau hauv sealants thiab adhesives,cenospheres tuaj yeem muab ntau yam txiaj ntsig,tshwj xeeb tshaj yog nyob rau hauv high-temperature applications . Nov yog qee lub luag haujlwm lawv ua:
Thermal rwb thaiv tsev : Cenospheres muaj cov khoom zoo heev insulating vim lawv cov qauv hollow. Thaum ntxiv rau sealants thiab adhesives, lawv tsim ib qho barrier uas txo cov cua sov hloov, yog li pab tiv thaiv substrate los yog sib koom ua ke los ntawm kub kub. Cov cuab yeej rwb thaiv tsev no yog qhov tshwj xeeb tshaj yog siv rau hauv cov ntawv thov uas cov cua sov dissipation yuav tsum tau txo qis.
Txo qhov ceev : Cenospheres yog lub teeb yuag, uas txhais tau tias lawv tuaj yeem txo qhov ceev tag nrho ntawm cov xov xwm thiab cov nplaum uas ua rau lawv cov qauv. Cov yam ntxwv ntawm lub teeb yuag no yog qhov xav tau hauv cov ntawv thov uas qhov hnyav ntawm cov khoom yuav tsum tau txo qis, xws li hauv aerospace lossis kev siv tsheb.
Txhim kho rheology : Qhov sib ntxiv ntawm cenospheres tuaj yeem txhim kho cov khoom rheological ntawm high-temperature sealants thiab adhesives. Lawv ua raws li cov tshuaj thixotropic, uas txhais tau hais tias lawv tuaj yeem pab tswj cov dej ntws thiab viscosity ntawm cov khoom. Cov cuab yeej no tso cai rau lub sealant los yog nplaum tau yooj yim thov, sib kis, thiab ua raws li qhov chaw thaum tuav nws cov duab thiab ruaj khov.
Txhim kho cov khoom siv kho tshuab : Cenospheres tuaj yeem txhim kho lub zog txhua yam thiab cuam tshuam tsis kam ntawm sealants thiab adhesives. Thaum sib xyaw ua ke, lawv tuaj yeem txhawb nqa cov khoom, txhim kho nws cov kev tiv thaiv kev ntxhov siab thiab deformation. Cov cuab yeej txhawb nqa no tshwj xeeb yog qhov muaj txiaj ntsig tshwj xeeb hauv cov ntawv thov kub kub uas cov khoom yuav raug thermal cycling lossis mechanical stresses.
Tshuaj tiv thaiv : Cenospheres muaj cov tshuaj tiv thaiv zoo, ua rau lawv tsim nyog rau cov ntawv thov uas lub sealant lossis nplaum yuav tsum tiv taus ntau yam tshuaj, acids, lossis alkalis. Lawv tuaj yeem pab txhim kho tag nrho cov tshuaj tiv thaiv ntawm cov khoom, txhim kho nws cov kav ntev thiab lub neej ntev.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias lub luag haujlwm tshwj xeeb thiab cov txiaj ntsig ntawm cenospheres nyob rau hauv high-temperature sealants thiab adhesives yuav txawv nyob ntawm seb cov formulation, daim ntawv thov, thiab lwm yam additives siv ua ke nrog lawv.
