Cov txiaj ntsig ntawm cov iav hollow microsphere hauv kev kho tsheb yog dab tsi?,
cov khoom siv ua kom txias hauv tsheb, cov iav hollow microspheres,
Cov iav me me uas khoob yog cov iav me me uas muaj qhov ceev tsawg, lub teeb yuag thiab lub zog siab. Vim yog cov yam ntxwv khoob, piv rau cov hlaws iav ib txwm, nws muaj cov yam ntxwv ntawm qhov hnyav tsawg, qhov ceev tsawg thiab kev ua haujlwm zoo ntawm kev rwb thaiv tsev. Cov txheej txheem no tau ntxiv ncaj qha rau hauv lub kaw lus txheej, yog li cov zaj duab xis txheej uas tsim los ntawm kev kho ntawm cov txheej muaj cov yam ntxwv rwb thaiv tsev thermal. Ntxiv rau nws qhov kev nqus roj tsawg thiab qhov ceev tsawg, ntxiv 5% (wt) tuaj yeem ua rau cov khoom tiav nce ntxiv los ntawm 25% txog 35%, yog li tsis ua rau nce lossis txo tus nqi ntim ntawm cov txheej.
Cov iav microspheres hollow yog cov hollow spheres kaw, uas tau ntxiv rau hauv lub txheej los tsim ntau lub microscopic ywj pheej thermal insulation cavities, yog li ntawd zoo heev txhim kho lub rwb thaiv tsev ntawm lub txheej zaj duab xis tiv thaiv cua sov thiab suab thiab ua lub luag haujlwm zoo hauv kev rwb thaiv tsev cua sov thiab txo suab nrov. Ua kom lub txheej txheej ntau dua dej tsis kam, tiv thaiv fouling thiab tiv thaiv xeb. Lub chemically inert nto ntawm cov microbeads yog resistant rau tshuaj corrosion. Thaum lub zaj duab xis yog tsim, cov khoom ntawm lub cov iav me me tau teeb tsa ze ze kom tsim tau qhov porosity qis, yog li ntawd qhov saum npoo ntawm txheej tsim cov zaj duab xis tiv thaiv uas muaj cov nyhuv thaiv cov dej noo thiab cov ions corrosive, uas ua lub luag haujlwm zoo hauv kev tiv thaiv.

Cov qauv kheej kheej ntawm cov hlaws iav khoob ua rau nws muaj cov nyhuv zoo rau kev cuam tshuam thiab kev ntxhov siab. Ntxiv nws rau hauv txheej txheej tuaj yeem txhim kho qhov kev tiv thaiv ntawm cov zaj duab xis txheej thiab tseem tuaj yeem txo qhov thermal nthuav dav thiab kev cog lus ntawm cov txheej. ntawm kev ntxhov siab tawg.

Zoo dua qhov ua kom dawb thiab ntxoov ntxoo. Cov hmoov dawb muaj qhov ua kom dawb zoo dua li cov xim ib txwm muaj, txo cov nqi ntawm lwm cov khoom kim heev thiab cov xim (piv nrog titanium dioxide, tus nqi ntim ntawm cov microbeads tsuas yog li 1/5) Ua kom zoo dua qhov lo rau ntawm qhov tsom ntawm txheej. Cov yam ntxwv nqus roj tsawg ntawm cov iav microbeads tso cai rau ntau cov resin koom nrog hauv kev tsim zaj duab xis, yog li ua rau qhov lo rau ntawm txheej ntau dua 3 txog 4 zaug.

Ntxiv 5% ntawm cov microbeads tuaj yeem ua rau qhov ceev ntawm txheej txheej los ntawm 1.30 mus rau qis dua 1.0, yog li txo qhov hnyav ntawm txheej txheej thiab zam qhov tshwm sim ntawm phab ntsa txheej tev tawm.

Cov microbeads muaj qhov cuam tshuam zoo rau cov duab ultraviolet, tiv thaiv cov txheej txheem los ntawm kev daj thiab kev laus.

Lub ntsiab lus melting siab ntawm cov microbeads txhim kho qhov kub thiab txias ntawm lub txheej thiab ua lub luag haujlwm zoo heev hauv kev tiv thaiv hluav taws. Cov khoom me me ntawm cov microbeads ua lub luag haujlwm ntawm cov bearings, thiab lub zog sib txhuam me me, uas tuaj yeem txhim kho kev ua haujlwm ntawm cov txheej thiab ua rau kev tsim kho yooj yim dua.

Cov lus qhia rau kev siv: Tus nqi ntxiv dav dav yog 10% ntawm tag nrho qhov hnyav. Cov microbeads yog kho qhov chaw thiab muaj qhov ceev qis, uas ua rau lub txheej yooj yim nce hauv viscosity thiab ntab thaum lub sijhawm khaws cia. Peb pom zoo kom nce qhov pib viscosity ntawm lub txheej (los ntawm kev nce qhov ntxiv ntawm cov thickener tswj cov viscosity saum 140KU), hauv qhov no, qhov tshwm sim ntab yuav tsis tshwm sim vim tias viscosity qis dhau, thiab cov khoom me me ntawm txhua yam khoom hauv lub kaw lus raug txo qis hauv kev ua haujlwm vim yog viscosity siab, uas yog qhov zoo rau kev tswj cov viscosity. Kev ruaj khov. Peb pom zoo kom siv txoj kev ntxiv hauv qab no: vim tias cov microbeads muaj cov phab ntsa me me thiab tsis tshua muaj shear tsis kam, txhawm rau siv tag nrho cov yam ntxwv hollow ntawm cov microbeads, nws raug pom zoo kom siv txoj kev ntxiv kawg, uas yog, muab cov microbeads tso rau ntawm qhov kawg ntawm qhov ntxiv yog dispersed los ntawm kev sib xyaw cov khoom siv nrog qhov ceev qis thiab qis shear zog ntau li ntau tau. Vim tias cov duab kheej kheej ntawm cov microbeads muaj cov kua dej zoo thiab kev sib txhuam ntawm lawv tsis loj, nws yooj yim rau disperse. Nws tuaj yeem ntub tag nrho hauv lub sijhawm luv luv, tsuas yog ncua lub sijhawm do kom ua tiav kev sib kis sib xws.

Cov microbeads tsis muaj tshuaj lom thiab tsis muaj kuab lom. Txawm li cas los xij, vim nws lub cev hnyav heev, yuav tsum tau saib xyuas tshwj xeeb thaum ntxiv nws. Peb pom zoo kom muaj ib txoj kev ntxiv ib kauj ruam zuj zus, uas yog, qhov ntau ntawm txhua qhov ntxiv yog 1/2 ntawm cov microbeads seem, thiab maj mam ntxiv, uas tuaj yeem tiv thaiv cov microbeads kom tsis txhob ntab mus rau hauv huab cua thiab ua rau qhov kev sib kis tiav dua. Cov iav hollow microspheres (HGMs) yog cov khoom siv sib dua, siv tau ntau yam uas pom cov ntawv thov hauv ntau yam lag luam, suav nrog kev tsim khoom tsheb. Hauv cov ntsiab lus ntawm kev kho tsheb tshiab, uas yuav hais txog kev txhim kho qhov zoo nkauj thiab kev ua haujlwm ntawm cov tsheb, HGMs muaj ntau qhov zoo:
Sib dua: Cov HGMs sib dua heev, uas pab txo qhov hnyav tag nrho ntawm cov khoom siv hauv tsheb. Cov tsheb sib dua feem ntau siv roj tsawg dua thiab muaj cov pa phem tsawg dua, ua rau muaj kev ruaj khov ntawm ib puag ncig thiab txuag nqi rau cov tswv.

Kev Rwb Thaiv Kub Zoo Dua: Cov iav me me uas muaj qhov khoob muaj cov cua sov tsawg. Thaum siv rau hauv cov khoom siv hauv tsheb, lawv tuaj yeem muab cov cua sov rwb thaiv, pab ua kom sab hauv ntawm lub tsheb txias dua thaum huab cua kub thiab txo qhov hnyav ntawm cov tshuab cua txias.

Kev Rwb Thaiv Suab Zoo Dua: Cov HGMs tuaj yeem siv rau hauv cov ntaub ntawv los txhim kho kev rwb thaiv suab. Qhov no ua rau sab hauv tsev ntsiag to dua, txo cov suab nrov ntawm txoj kev thiab muab kev tsav tsheb xis dua.

Kev Ruaj Ntseg ntawm Qhov Loj: HGMs tuaj yeem txhim kho qhov ruaj ntseg ntawm cov khoom siv. Hauv cov ntsiab lus ntawm cov khoom siv hauv tsheb, qhov no txhais tau tias cov khoom siv yuav tsis yooj yim khoov lossis hloov pauv cov duab hauv qab qhov kub thiab txias sib txawv, ua rau cov khoom siv tau ntev dua thiab ruaj khov dua.

Qhov Chaw Zoo Dua: Thaum siv rau hauv cov xim thiab cov tshuaj pleev xim, HGMs tuaj yeem pab ua kom qhov chaw du thiab tiaj tus. Qhov no tseem ceeb heev rau cov ntawv thov tsheb, qhov twg qhov pom ntawm lub tsheb yog qhov tseem ceeb rau cov neeg siv khoom.

Kev Txhim Kho Lub Zog Sib Txuas: HGMs tuaj yeem txhim kho lub zog sib txuas ntawm cov nplaum thiab cov txheej txheej. Hauv kev kho tsheb, cov khoom no muaj txiaj ntsig zoo rau kev ua kom cov khoom tshiab lossis cov txheej txheej lo rau ruaj khov rau cov khoom siv tsheb uas twb muaj lawm, txhim kho kev ruaj khov tag nrho.

Kev Siv Nyiaj Tau Zoo: Txawm hais tias tus nqi pib ntawm kev siv HGMs rau hauv cov khoom siv yuav siab dua, cov txiaj ntsig ntawm kev siv cov khoom siv tsawg dua, kev siv roj zoo dua, thiab cov khoom siv ntev dua tuaj yeem ua rau txuag tau nyiaj mus ntev.

Kev Kho Kom Haum: Cov HGMs tuaj yeem tsim kom muaj cov yam ntxwv tshwj xeeb, xws li qhov loj me, qhov ceev, thiab qhov tuab ntawm lub plhaub. Qhov no tso cai rau cov chaw tsim khoom kho cov microspheres raws li qhov xav tau ntawm cov kev siv tsheb tshwj xeeb, kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws.

Ib puag ncig zoo: Cov iav microspheres hollow feem ntau yog ua los ntawm cov iav rov ua dua tshiab thiab zoo rau ib puag ncig. Kev siv cov ntaub ntawv zoo rau ib puag ncig ua raws li kev tsom mus rau kev ruaj khov hauv kev lag luam tsheb.

Hauv kev xaus, cov iav hollow microspheres muaj ntau yam zoo hauv kev kho tsheb, suav nrog kev tsim kho lub teeb yuag, kev rwb thaiv tsev thermal thiab acoustic zoo dua, kev ua tiav ntawm qhov chaw, thiab kev siv nyiaj tsawg, ua rau lawv muaj txiaj ntsig zoo rau kev txhim kho kev ua tau zoo thiab kev zoo nkauj ntawm cov tsheb.

Peb muaj ntau yam Hollow Glass Microspheres, yog tias koj muaj lus nug ntxiv, thov tsis txhob yig tiv tauj peb. Peb tus neeg sawv cev muag khoom thiab cov engineers yuav muab kev txhawb nqa zoo tshaj plaws rau koj!
