Ntau Cenospheres, Ntau Daim Ntawv Thov

Txawm hais tias koj yuav tsis paub nws, lub ntiaj teb niaj hnub no muaj ntau yam laj thawj los ua tsaug rau cov cenospheres.

Muaj tsawg tus neeg paub txog lawv lub neej, txawm tias muaj tsawg tus neeg paub tias lawv los qhov twg los. Txawm hais tias saib Wikipedia sai sai, qhov chaw ntawm txhua qhov chaw, yuav qhia rau cov neeg tsis paub tias, "Lub cenosphere yog lub pob zeb tsis hnyav, inert, hollow ua los ntawm silica thiab alumina thiab puv nrog cua lossis inert roj, feem ntau tsim los ua cov khoom lag luam ntawm kev hlawv thee ntawm cov chaw tsim hluav taws xob thermal. Cov xim ntawm cenosphere sib txawv ntawm grey mus rau yuav luag dawb thiab lawv qhov ceev yog li 0.4–0.8 g / cm3 (0.014–0.029 lb / cu hauv), uas ua rau lawv zoo heev. "

Txawm li cas los xij, qhov ntawd tsis piav qhia txog qhov zoo nkauj tiag tiag ntawm cov pob me me no, tab sis muaj zog, ntawm cov tshauv ya. Rau lawv lub zog tiag tiag yog nyob rau hauv ntau yam ntawm lawv siv. Raws li phau ntawv xov xwm kev lag luam Fabkis, Industrie & Technologies, hais tias, "Vim lawv qhov ceev qis, me me, lub voj voog, lub zog kho tshuab, kub yaj siab, tshuaj inertia, cov khoom rwb thaiv tsev thiab porosity qis, microspheres [tseem hu ua cenospheres] pom ntau yam kev siv hauv kev lag luam. Tshwj xeeb, [lawv zoo tagnrho] rau cov ntaub ntawv txhawb nqa lossis muab cov khoom tiv taus corrosion, lossis thermal thiab suab rwb thaiv tsev rau cov txheej lossis xim. Lawv tuaj yeem piav qhia tias yog cov khoom siv ntau yam thiab sib xyaw zoo hauv cov resins thiab binders xws li thermoplastics thiab thermosetting. "

Cenospheres hauv Cov Xim thiab Cov Tshuaj Pleev Xim

Muaj ntau yam kev siv rau cenospheres hauv kev lag luam pleev xim thiab kev lag luam txheej, vim yog cov yam ntxwv ntxiv uas lawv muab. Piv txwv li, cenospheres feem ntau siv rau hauv cov txheej txheej los tswj cov hluav taws xob infrared, muab cov txheej txheej ntawd kom zoo dua li cov uas tsuas yog sim txwv cov thermal conductivity.

Lub caij no, cov kws tshaj lij txheej ntawm Petra Buildcare Products, piav qhia txog cenospheres, "... txhim kho qhov zoo ntawm cov xim los ntawm kev txhim kho qhov ntim thiab qhov ceev ntawm cov khoom. Tom qab thov rau ntawm phab ntsa, cov hlaws dai ceramic feem ntau yuav ntsws ua rau muaj zaj duab xis nruj ntawm phab ntsa."

Cenospheres hauv Syntactic Foams

Cov cenospheres feem ntau siv los ua 'syntactic foams'. Cov no yog cov khoom khov tshwj xeeb uas siv cenospheres ua ib qho khoom sau los muab ntau yam zoo, los ntawm tus nqi qis dua, mus rau lub zog ntxiv, kev tiv thaiv suab nrov, kev ntab thiab kev tiv thaiv thermal.

Cov kws tshaj lij ntawm Engineered Syntactic Systems piav qhia txog syntactic ua npuas ncauj raws li hauv qab no;

"Qhov 'syntactic' feem yog hais txog cov qauv uas tau muab los ntawm cov pob zeb hollow. Lo lus 'ua npuas' cuam tshuam txog qhov xwm txheej ntawm cov khoom siv. Ua tsaug rau nws cov khoom tshwj xeeb ntawm lub zog siab ntawm qhov ceev qis, ua npuas syntactic tau siv dav hauv cov ntawv thov buoyancy hauv qab dej hiav txwv. Cov ntaub ntawv syntactic tiv taus cov nyhuv ua ke ntawm hydrostatic siab thiab kev raug mob ntev uas ua rau lawv zoo tagnrho rau cov haujlwm oceaneering xws li cable thiab hardball floats thiab kev txhawb nqa cov cuab yeej siv. Lawv kuj muab lub zog thiab kev ua kom zoo ntawm cov qauv ntawm qhov hnyav qis dua ib ntim dua li feem ntau cov ntaub ntawv ib txwm muaj uas ua rau lawv yog qhov kev xaiv zoo hauv ntau daim ntawv thov kev tiv thaiv thiab kev tsim kho vaj tse. "

Cenospheres hauv Petroleum Drilling

Yog xav paub txog qhov tseem ceeb ntawm cov cenospheres uas tsis paub, koj tsis tas yuav nrhiav ntxiv lawm tias lawv lub luag haujlwm tseem ceeb hauv kev lag luam roj av. Thaum txhua tus paub txog qhov tseem ceeb ntawm roj hauv lub ntiaj teb niaj hnub no, nws yog qhov tseeb me ntsis uas paub tias cenospheres, raws li phau ntawv xov xwm kev lag luam Fabkis, Industrie & Technologies, hais tias, "... tau siv rau ntau xyoo hauv kev khawb roj los txo qhov ceev ntawm cov roj av cement tsis muaj kev nce cov dej hauv cov roj."

Cenospheres hauv Plastics thiab Polymers

Cenospheres kuj muaj kev siv rau hauv kev tsim cov yas thiab polymers, vim lawv cov duab rov ua dua lossis lub zog pab kom tsis txhob muaj kev ntswj hauv cov thermoplastics thiab thermosetting plastics.

Lawv kuj tseem siv rau hauv cov khoom sib xyaw niaj hnub hauv kev lag luam tsheb. Piv txwv li, xyoo 2016 Chevrolet Corvette muaj "cov khoom sib xyaw ua ke uas cov iav microspheres hloov cov calcium carbonate filler thiab txiav 20 phaus [9kg] tawm ntawm lub tsheb kis las Stingray Coupe qauv hnyav." Tus Lwm Thawj Coj ntawm lub chaw tsim khoom, Continental Structural Plastics Inc., Probir Guha, piav qhia txog qhov laj thawj rau kev suav nrog cov cenospheres hauv cov khoom sib xyaw, hauv kev hais tias, "cov mis SMC ib txwm muaj rau hom kev siv tsheb no muaj 20% los ntawm qhov ntim ntawm cov iav fiber reinforcement, 35% resin thiab 45% filler, feem ntau yog calcium carbonate," ntxiv tias, "SMC tshiab no [cov khoom sib xyaw ua ke] yog tus nqi sib tw nrog txhuas."

Cenospheres hauv Concrete

Tau ntau xyoo, cenospheres tau ua ib qho khoom siv ntxiv rau cov pob zeb ua vaj tse, muab lub zog ntxiv, thiab lossis kev rwb thaiv suab, thaum tseem txo qhov ceev. Jeff Girard, Thawj Tswj Hwm ntawm Lub Koom Haum Concrete Countertop, piav qhia txog cov txiaj ntsig no, hais tias, "Hauv kev xav, cenospheres tuaj yeem hloov qee cov xuab zeb hnyav ib txwm siv hauv cov pob zeb ua vaj tse. Cenospheres muaj qhov ceev uas tsawg dua dej (nruab nrab 0.7 vs. Dej 1.0); cov xuab zeb quartz feem ntau muaj qhov ceev ntawm kwv yees li 2.65. Qhov no txhais tau tias 1 phaus ntawm cenospheres siv tib qhov ntim tag nrho li kwv yees li 3.8 lbs. ntawm xuab zeb."

Industrie & Technologies, kuj piav qhia txog kev siv cov cenospheres ua ib txoj hauv kev los txo cov suab nrov, hais tias, "[Cenospheres siv] hauv cov ntaub ntawv tsim kho kom lub pob zeb sib zog, thaum tswj lub zog compressive ntawm 30 MPa ntawm qhov ceev ntawm 1.6 T / m3, txhim kho lawv qhov nruj thiab txo lawv cov suab kis. Piv txwv li, St. Petersburg Scientific thiab Technical Center of Applied Nanotechnologies (STCAN) koom nrog kev tsim cov choj nrog cov concretes zoo li no hauv Russia, [rau txoj kev ntsiag to dua]. Cenospheres kuj tseem siv los txhim kho cov cua sov thiab suab rwb thaiv tsev zoo ntawm plasters, mortars thiab plasters, siv rau phab ntsa, pem teb thiab qab nthab. Kev ntxiv ntawm 40% ntim cenospheres ib nrab ntawm cov coefficient kis suab nrov.

Cenospheres hauv Pharmaceuticals

Cov cenospheres tau siv rau hauv kev lag luam tshuaj tau ntau xyoo, vim tias cov pob me me tuaj yeem ua haujlwm zoo li lub cuab yeej thauj khoom thaum coated nrog tshuaj. Tsis tas li ntawd, raws li phau ntawv xov xwm kev lag luam Fabkis, Industrie & Technologies, sau tseg, "Cenospheres them nrog silver oxide, piv txwv li, yuav raug koom ua ke rau hauv cov ntaub qhwv kom ua kom cov qhov txhab kho sai dua."

Cenospheres hauv Kev Lag Luam Siab Tshaj Plaws

Muaj ntau txoj kev tshawb fawb tab tom ua los nrhiav kev siv tshiab rau cov khoom lag luam no. Piv txwv li, cov tshuaj tshiab rau cov txheej txheem oxidation methane tab tom raug tsim los ntawm kev siv cov cenospheres sib nqus.

Cov Cenospheres kuj tseem siv rau hauv kev tsim cov hlau matrix composites (MMC), ntau yam khoom siv uas sim ua ke qhov kev nqus hluav taws xob siab, kev tiv thaiv kev cuam tshuam, thiab qhov ceev qis ntawm cov pob zeb nrog cov yam ntxwv ntawm lwm yam khoom. Lwm tus, xws li Paul Biju-Duval ntawm Georgia Institute of Technology nyob hauv Atlanta, tau ua haujlwm hnyav hauv kev tsim cov khoom siv hauv tsev tsis muaj cement. Nws txoj haujlwm txuas ntxiv mus, ntxiv rau qhov sib xyaw cenosphere, cov khoom xws li xyoob thiab cov yeeb nkab hlau ua ib txoj hauv kev los nrhiav lwm txoj hauv kev, pheej yig dua, muaj zog dua, thiab zoo dua rau ib puag ncig.

Lub caij no, Lub Tsev Kawm Ntawv ntawm Chemistry thiab Chemical Technology ntawm Lavxias Academy of Sciences hauv Krasnoyarsk, tab tom kawm txog txoj hauv kev uas cenospheres tuaj yeem siv rau hauv kev hloov pauv catalytic. Thaum BAE systems tab tom sim siv cenospheres hauv xim ua ib txoj hauv kev los txhawb kev tsis pom kev hauv infrared spectrum, yog li ua rau cov tub rog muaj 'invisibility cloaks'.

Nrog rau ntau yam kev siv, thiab ntau yam kev siv tau ntau dua, nws tsis yog qhov xav tsis thoob tias vim li cas kev txaus siab rau cenospheres thiaj li loj hlob. Tsuav yog cov neeg tsim khoom tab tom nrhiav cov khoom siv sib dua, cov txheej txheem xa tshuaj zoo dua, cov txheej txheem zoo dua, cov khoom siv hloov cement, thiab cov khoom sib xyaw ua ke, ces yuav muaj kev xav tau cenospheres. Ntxiv rau qhov kev tshawb fawb ntxiv rau kev siv tshiab rau cov spheres no, ces tsuas yog lub sijhawm yuav qhia qhov twg yav tom ntej ntawm cenospheres nyob.
