Cov Cenospheres yog ib yam khoom uas tau rho tawm los ntawm cov tshauv yaNws muaj ntau yam khoom xws li qhov loj me me, thaj chaw loj, thiab kev rwb thaiv hluav taws xob zoo heev. Nws siv dav hauv ntau qhov chaw. Cov txiaj ntsig ntawm kev siv hauv kev lag luam txheej yog dab tsi?
A- Cov txiaj ntsig ntawm cenospheres hauv kev lag luam txheej
1. Tus nqi ntawm cov resin yog me me. Vim yog qhov chaw me me ntawm lub voos xwmfab hauv txhua yam duab, cov hlaws dai xav tau cov resin tsawg dua. Kev ntim khoom me me kuj tau txhim kho. Qhov faib tawm dav dav ntawm cov cenospheres ua rau cov microspheres me me sau cov voids ntawm cov microspheres loj.
2. Txhim kho kev ua kua. Tsis zoo li cov khoom me me uas tsis sib xws, cov cenospheres dov tau yooj yim ntawm ib leeg, txhim kho kev ua kua. Qhov no ua rau cov viscosity qis dua thiab cov yam ntxwv ntws zoo dua rau cov kab ke siv cenospheres. Tsis tas li ntawd, kev txau tau zoo dua.
3. Kev ua kom muaj zog thiab muaj zog. Cov Cenospheres yog cov microspheres muaj zog, tawv uas ua kom lub zog, txhuam tsis kam thiab kev puas tsuaj ntawm cov txheej txheem.
4. Cov nyhuv rwb thaiv tsev zoo. Vim yog cov qauv hollow spherical ntawm cenospheres, nws muaj cov nyhuv rwb thaiv tsev zoo heev thaum sau cov txheej txheem.
5. Muaj peev xwm tswj tau qhov ci ntsa iab. Ua ib qho khoom sau, cenospheres tuaj yeem txo qhov ci ntsa iab, thiab txawm tias thaum muaj qhov xav tau ntxiv ntau, lawv tuaj yeem tshem tawm qhov nce ntxiv ntawm viscosity uas cov neeg sawv cev matting feem ntau ua rau, thiab lawv kuj pheej yig.
6. Cov khoom xyaw tshwj xeeb uas tsis muaj zog. Cov cenospheres yog tsim los ntawm cov khoom xyaw uas tsis muaj zog, ua rau muaj kev ruaj khov zoo heev, tiv taus huab cua, tiv taus xeb thiab tiv taus tshuaj lom neeg.
7. Ua kom npog ntau dua. Cov cenospheres yog cov pob zeb khoob uas qeeb thiab tawg lub teeb thiab tsis pom kev, uas ua rau lub zog zais ntawm cov xim ua rau ntau dua.
8. Kev tawg ua tej daim me me. Cov cenospheres tawg ua tej daim me me zoo li cov khoom siv hauv cov pob zeb. Vim lawv cov phab ntsa tuab thiab lub zog compressive siab, cov cenospheres tuaj yeem tiv taus kev ua cov khoom sib tov, cov extruders thiab cov tshuab molding.
9. Tsis muaj kuab paug crystalline silicon. Tsis zoo li lwm cov khoom sau, cov ntsiab lus ntawm crystalline silicon hauv cenospheres qis dua qib tsis txaus ntshai. Cenospheres tsis suav tias yog txaus ntshai thiab tsis xav tau cov cim ceeb toom tshwj xeeb.
Qhov thib ob, cov khoom siv tseem ceeb uas siv los ntawm cenospheres
B. Txheej txheej rwb thaiv tsev kub
Vim tias qhov kub thiab txias ntawm cenospheres siab txog li 1500 degrees thiab qhov thermal conductivity me me, nws tuaj yeem ntxiv rau txheej ua cov khoom siv rwb thaiv tsev thermal, uas tuaj yeem ua rau cov nyhuv rwb thaiv tsev thermal ntawm txheej. Siv cenospheres ua cov khoom siv tseem ceeb, cov ntsiab lus qis-khoom kub siab-resistant thermal rwb thaiv tsev tshuaj tsuag txheej tau npaj, uas muaj cov yam ntxwv ntawm lub teeb thiab tswj tau shrinkage tom qab hlawv. Qee tus kws tshawb fawb pom tias kev ntxiv cenospheres rau txheej tau txhim kho cov nyhuv rwb thaiv tsev thermal ntawm txheej. Thaum cov koob tshuaj yog 9%, cov nyhuv rwb thaiv tsev thermal yog qhov zoo tagnrho.
2. Hluav taws kub retardant tiv taus hluav taws txheej
Cov cenospheres muaj qhov kub siab refractory thiab muaj cov yam ntxwv ntawm tsis kub hnyiab, tsis deformation thiab tsis muaj pa luam yeeb nyob rau hauv qhov kub siab. Lawv yog cov khoom siv inorganic tsis yog hlau uas tiv taus hluav taws thiab hluav taws kub thiab yog cov khoom zoo rau kev tsim cov txheej txheem hluav taws kub thiab hluav taws kub. Ntxiv li 60 feem ntawm cov xim sib xyaw nrog ntau dua 10 hom khoom siv raw, cov khoom muaj kev sib txuas zoo heev, cov nyhuv hluav taws kub zoo thiab cov nyhuv txo suab nrov zoo kawg nkaus, thiab muaj kev tiv taus kub thiab qis zoo kawg nkaus.
3. Cov txheej txheem tiv thaiv xeb rau kev lag luam
Cov cenospheres kuj tau ua tiav cov txiaj ntsig zoo hauv kev tiv thaiv xeb thiab tiv thaiv xeb. Nws tuaj yeem ntxiv 6 ~ 10 cov ntsiab lus ntawm cenospheres los npaj cov qauv hlau tsis nthuav dav tiv thaiv xeb txheej, uas feem ntau yog siv rau kev tiv thaiv xeb ntawm cov qauv hlau hauv kev tsim kho ntawm qhov project. Cov txheej txheem muaj kev tiv thaiv corrosion zoo thiab kub siab tiv taus, thiab siv rau hauv cov khoom siv tshuaj lom neeg. Tsis yooj yim poob tawm, lub neej ua haujlwm ntev.
4. Txheej tiv dej tsis nkag
Tus nqi nqus dej ntawm cenospheres qis, kwv yees li 5%, thiab cov dej ntws zoo li cov dej lwg ntawm cenospheres, qhia tias cenospheres muaj kev ua tau zoo tiv thaiv dej thiab tuaj yeem siv ua cov khoom sau rau cov txheej tiv thaiv dej. Cov txheej tiv thaiv dej polymer cement yog tsim los ntawm kev siv cov hlaws dai ntab thiab montmorillonite, ntxiv cenospheres, txhim kho qhov fluidity ntawm cov cement slurry thiab txo cov nqi tsim khoom. 15% cenospheres raug ntxiv rau hauv kev tsim khoom, thiab cov khoom muaj kev ua tau zoo tiv thaiv dej.
5. Lwm cov txheej txheem
Siv cov cenospheres ua cov khoom sau, ntxiv rau cov txheej saum toj no, cov hmoov qhuav uas muaj cov thermal conductivity qis, reflectivity siab, hnav tsis kam siab, nplaim taws tsis kam thiab huab cua tsis kam kuj tseem tuaj yeem tsim tau. Nws muaj kev tiv thaiv corrosion thiab acid thiab alkali tsis kam. Thaum cov txheej nyias heev, nws yog flammable thiab muaj kev ua tau zoo tiv thaiv xob laim.
