Kev siv cov hollow iav microspheres hauv txheej txheej

Hollow iav microspheresyog siv los ua ib qho hollow, hnav thiab siab zog multifunctional muab tub lim nyob rau hauv ib tug ntau yam ntawm haumxeeb txheej. Qhov sib ntxiv ntawm hollow iav microspheres hauv cov txheej txheej tuaj yeem ua tau raws li qhov xav tau ntawm kev ua haujlwm tshwj xeeb, ua kom cov txheej txheem siv rau ntau yam kev tiv thaiv hnyav thiab tshwj xeeb acoustic thiab thermal rwb thaiv tsev.
Lub luag haujlwm ntawm hollow iav microspheres hauv txheej txheej:
Xim zoo:
Hollow iav microspheres yog dawb huv thiab muaj tej yam matting, whitening thiab masking los thaum siv nyob rau hauv coatings.
Tsawg ceev:
Hollow iav microspheres muaj qhov ntom ntom ntom ntom, uas tuaj yeem txo qhov hnyav ntawm cov txheej hauv txheej, yog li txo cov nqi thauj khoom thiab cov khoom siv.
Zoo thermal rwb thaiv tsev:
Sab hauv ntawmhollow iav microspheresyog inert gas, thiab muaj qhov ntom ntom thiab thermal conductivity sib txawv ntawm ob yam khoom sib txawv, uas ua rau lawv muaj kev rwb thaiv tsev kub, suab rwb thaiv tsev thiab thermal conductivity tsawg. Hollow iav microspheres muaj cov cua kub tsis tshua muaj cua sov hloov coefficient, tsim cov txheej txheem thermal thaiv txheej hauv txheej txheej, uas tuaj yeem tiv thaiv kev hloov pauv ntawm cov cua sov mus rau hauv lub tsev, yog ib qho kev siv thermal barrier muab tub lim rau hauv cov txheej txheem, thiab tuaj yeem siv los sau ntau yam cua sov-insulating thiab thermal-retaining coatings. Hollow iav microspheres kuj tseem siv tau los tiv thaiv cov zaj duab xis txheej los ntawm thermal shocks tshwm sim los ntawm kev hloov pauv ntawm qhov kub thiab txias.
Zoo flowability thiab seem stability:
Hollow iav microspheres yog cov pob me me uas tau yooj yim tawg thiab muaj dej ntws zoo thiab qib hauv cov txheej txheej. Ntxiv mus, lub puag ncig spheres yog isotropic, uas tuaj yeem zam kev shrinkage thiab warping ntawm txheej.
Txhim kho cov xim zaj duab xis kev ua tau zoo
Tus qauv ntawmhollow iav microspheresnyob rau hauv cov duab kheej kheej tuaj yeem cuam tshuam qhov cuam tshuam thiab kev ntxhov siab, yog li cov txheej txheem muaj qee yam kev cuam tshuam rau sab nraud, thiab tib lub sijhawm, nws tuaj yeem txo qhov kev ntxhov siab ntawm cov txheej vim thermal expansion thiab contraction.
Ntau dua resin hloov tus nqi, tus nqi qis dua
Hollow iav microspheres muaj qhov tshwj xeeb ntawm thaj chaw thiab cov roj tsawg nqus, uas muaj qhov zoo dispersibility thiab sau rau hauv txheej. Cov roj tsawg nqus tau zoo tuaj yeem ua rau kom ntau npaum li cas ntawm cov fillers, txo qhov ntau npaum li cas ntawm cov resin, thiab paub txog kev ua haujlwm zoo heev yam tsis tau nce lossis txo tus nqi ntawm ib chav tsev ntim ntawm txheej txheej.
Piv txwv ntawm kev siv ntawm hollow iav microspheres nyob rau hauv lub tshav pob ntawm coatings:
Heavy anti-corrosion txheej:
Hollow iav microspheres tuaj yeem siv rau hauv epoxy zinc nplua nuj txheej thiab ua lub luag haujlwm tseem ceeb hauv txheej txheej. Lub ntim nyhuv ntawm hollow iav microspheres pab txhim kho cov dispersion ntawm zinc hmoov. Lawv cov qauv kheej kheej tsis tsuas yog txhim kho cov kua dej ntawm cov xim, tab sis kuj tiv thaiv cov yeeb yaj kiab los ntawm shrinking lossis warping vim kev ntxhov siab tsis sib xws thiab txhim kho kev cuam tshuam. Hollow iav microspheres hauv cov xim zaj duab xis kuj tseem tuaj yeem tiv thaiv cov khoom siv corrosion, xws li chlorides, oxides, thiab lwm yam, yog li tiv thaiv cov khoom corrosive los ntawm kev sib cuag nrog lub substrate, kom lub substrate tau ruaj khov mus ntev tiv thaiv.
Thermal rwb thaiv tsev xim:
Hollow iav microspheres muaj cov thermal conductivity tsawg, nyob rau hauv cov xim thermal rwb thaiv tsev kev ua tau zoo muaj ib tug dav daim ntawv thov kev cia siab. Piv txwv li, thaum siv sab nrauv reflective thermal rwb thaiv tsev txheej, lawv tuaj yeem cuam tshuam lub hnub ci thiab muaj qhov cuam tshuam zoo thermal rwb thaiv tsev. Qhov qis thermal conductivity ntawm hollow iav microspheres tuaj yeem siv los npaj cov txheej txheem kub resistant.
Anti-stone coatings (automobile primer):
Hollow iav microspherestuaj yeem siv rau hauv PVC los tiv thaiv pob zeb cuam tshuam coatings, nws cov qauv hollow, nyob rau hauv qhov cuam tshuam yuav nqus, zom qhov cuam tshuam lub zog, txhim kho qhov cuam tshuam ntawm cov khoom, tib lub sijhawm, hollow iav microspheres muaj qhov ntom ntom, rau kev txo nqi thiab lub tsheb sib zog kuj ua lub luag haujlwm tseem ceeb.
Raws li hom tshiab ntawm cov khoom siv muab tub lim, hollow iav microspheres muaj cov yam ntxwv tshwj xeeb uas ua rau lawv siv dav hauv ntau qhov chaw. Los ntawm kev ntxiv hollow iav microspheres, kev ua haujlwm ntawm cov txheej txheem tuaj yeem txhim kho thiab ua haujlwm ntawm cov txheej txheem tuaj yeem txuas ntxiv. Qhov kev ua tau zoo ntawm hollow iav microspheres ua rau lawv muaj kev cia siab rau daim ntawv thov dav.
