Hollowiav hlawss yog ib qho hollow, lub teeb yuag thiab lub zog muaj zog multifunctional muab tub lim uas tau siv dav hauv ntau hom txheej txheej. Ntxiv hollow iav hlaws rau txheej txheej tuaj yeem ua tau raws li cov kev xav tau tshwj xeeb, tso cai rau cov coatings siv rau hauv ntau yam hnyav-tiv thaiv corrosion thiab tshwj xeeb suab rwb thaiv tsev thiab tshav kub rwb thaiv tsev teb.
Lub luag haujlwm ntawm hollow iav hlaws hauv txheej txheej:
Cov xim zoo: hollow iav hlaws yog dawb huv, thiab lawv muaj qee yam matting, whitening thiab npog cov teebmeem thaum siv cov coatings.
Txo qhov ntom ntom: hollow iav hlaws muaj qhov ntom ntom, uas tuaj yeem txo qhov hnyav ntawm cov txheej hauv txheej, yog li txo cov load thiab txo cov nqi khoom.
Zoo thermal rwb thaiv tsev: Sab hauv ntawm lub hollow iav hlaws dai yog inert gas, thiab ob yam khoom sib txawv muaj qhov sib txawv ntawm qhov ntom ntom thiab thermal conductivity, uas ua rau lawv muaj cov yam ntxwv ntawm cov rwb thaiv tsev kub, suab rwb thaiv tsev thiab thermal conductivity tsawg. Hollow iav microspheres muaj qis cua kub hloov pauv coefficient thiab tsim cov txheej txheem thermal thaiv txheej hauv txheej, uas tuaj yeem ncua kev hloov pauv ntawm cov cua sov mus rau lub tsev. Nws yog ib qho kev siv thermal barrier muab tub lim hauv cov txheej txheem thiab tuaj yeem siv los sau ntau yam thermal rwb thaiv tsev txheej. Lub thermal rwb thaiv tsev ntawm hollow iav microspheres kuj tseem siv tau los tiv thaiv cov txheej txheem los ntawm thermal shock tshwm sim los ntawm kev sib hloov ntawm cov cua kub ceev thiab ceev txias txias.
Zoo fluidity thiab zoo seem stability: hollow iav hlaws dai yog me me spheres uas yooj yim rau disperse thiab muaj zoo txaus thiab leveling zog nyob rau hauv coatings. Ntxiv mus, cov khoom kheej kheej yog isotropic, uas tuaj yeem zam kev shrinkage thiab warping ntawm txheej.
Txhim kho qhov kev ua tau zoo ntawm cov xim zaj duab xis Cov qauv kheej kheej ntawm lub hollow iav hlaws tuaj yeem cuam tshuam qhov cuam tshuam ntawm kev quab yuam thiab kev ntxhov siab, yog li cov txheej txheem muaj qee yam tsis zoo rau kev cuam tshuam sab nraud, thiab tib lub sijhawm tuaj yeem txo qhov kev ntxhov siab tawg los ntawm thermal expansion. thiab contraction ntawm txheej.
Ntau dua resin hloov pauv tus nqi, tus nqi qis dua hollow iav hlaws muaj qhov tshwj xeeb ntawm thaj chaw siab thiab qis roj nqus tus nqi, thiab muaj qhov zoo dispersibility thiab sau cov khoom hauv txheej. Tsawg roj nqus tus nqi tuaj yeem ua rau kom cov khoom ntim tau zoo, txo cov nqi ntawm cov resin, thiab ua tiav cov filling tsis tau nce lossis txo cov nqi ntim ntawm cov txheej.
