Fly tshauv thiab Cenospheres

ya tshauv, ib qho khoom siv los ntawm cov thee hluav taws xob hluav taws xob hluav taws xob hluav taws xob, yog cov khoom siv pozzolanic lees paub tias yog cov khoom muaj txiaj ntsig uas tuaj yeem muab ntxiv rau cov ntaub ntawv tsim kho los tsim cov cementitious compounds thaum sib cuag nrog dej.Cenospheres , hollow, spherically zoo li tus hais uas feem ntau qhib-pore hom nyob rau hauv cov xwm, yog ib qho tseem ceeb tshaj plaws nqi-ntxiv cov ntaub ntawv los yog subproducts uas sib tov nrog ya tshauv. Qhov no yog vim muaj cov yam ntxwv tshwj xeeb ntawm cenospheres, xws li lub teeb yuag, zoo flowability, tshuaj inertness, zoo rwb thaiv tsev, siab compressive zog, thiab thermal conductivity tsawg, uas ua rau lawv tau dav siv nyob rau hauv ntau daim ntawv thov kev lag luam. Cenospheres tau dhau los ua cov khoom xav tau los ua cov khoom siv los yog cov khoom ntxiv hauv ntau daim ntawv thov tshwj xeeb, xws li hauv cov cement yuag, polymeric composites, automotive nres rotors, thiab sib txawv npog, mullite-coated diesel cav Cheebtsam, thiab electromagnetic shielding thiab zog nqus daim ntaub ntawv. . Cov ntawv thov rau cenospheres raws li cov khoom siv tsim kho tau pom, xws li hauv lub teeb yuag thermal rwb thaiv tsev sib xyaw, lub teeb yuag suab-absorbing cov khoom siv nrog cenosphere-reinforced cement thiab asphalt pob zeb, thiab cov pob zeb sib sib zog nqus. Nws tau raug tshaj tawm tsis ntev los no tias cenospheres tau siv los ua cov khoom siv ntxiv lossis muab tso rau hauv cov khoom siv polymer rau kev tsim cov kab hluav taws xob sib xyaw thiab cov tsheb ciav hlau sib xyaw. Nrog lawv cov kheej kheej thiab hollow morphologies, cenospheres yog qhov tshwj xeeb tshaj yog cog lus, nrog siab tiv thaiv kom tawg tawm.
Qhov ceev ntawm cenospheres txawv ntawm 0.2 g / cc txog 2.6 g / cc. Qhov muaj xws li tsawg-density (Cov txheej txheem uas twb muaj lawm ntawm kev sib cais cenosphere tau muab faib ua ob pawg: kev sib cais ntub dej thiab kev sib cais qhuav. Cov txheej txheem ntub dej sib cais yog nyob ntawm qhov sib txawv ntawm qhov sib txawv ntawm qhov ntom ntawm cov khoom thiab cov kua nruab nrab: nrog rau cov txheej txheem no, cenospheres tuaj yeem rov qab los ntawm ya tshauv los ntawm lub ntiajteb txawj nqus kev sib cais-lub dab dej-float txoj kev sib cais ntawm kev sib cais ntub dej yog ua raws li lub ntuj buoyancy ntawm cenospheres nyob rau hauv nruab nrab, qhov concentration ntawm cov khoom noj, qhov saum npoo topology, thiab porosity ntawm. particles, thiab refinement cycles Txawm li cas los, lub efficiency yog txwv los ntawm lub zog ntawm cov tuab tuab ntawm ya tshauv, uas tiv thaiv particles lighter tshaj dej los ntawm escaping lub agglomeration, yog li ntawd hindering qhov nce ntawm lub lighter hais rau saum npoo Kev sib cais ntub dej yog qhov muaj peev xwm ntawm tau txais cov qes, tsis muaj txiaj ntsig, muaj kev txhawj xeeb ntawm cov av thiab dej loj rau cov khoom loj. Lwm qhov teeb meem yog qhov teeb meem ntawm kev tawg ntawm cov khoom phom sij rau hauv cov dej. Ib qho teeb meem ntxiv yog qhov xav tau rau kev ziab ntxiv ua ntej siv ntxiv. Nyob rau hauv cov nqe lus ntawm cov khoom zoo (tshwj xeeb tshaj yog rau chav kawm C ya tshauv nrog cov ntsiab lus calcium siab), muaju yog tsim nyob rau hauv particle deg thiab tom qab ntawd ua hardened nyob rau hauv qhuav theem, thiaj li txwv lawv siv rau kev siv ntxiv. Kev sib cais qhuav yog lwm txoj hauv kev los daws cov teeb meem ntawm kev sib cais ntub dej. Nrog rau txoj kev no, cov tshuaj muaj pes tsawg leeg tseem tsis hloov pauv. Tsis tas li ntawd, tsis muaj qhov xav tau ziab kom qhuav, yog li zam qhov teeb meem ntawm kev siv hluav taws xob: txawm li cas los xij, txoj kev no yuav tsum tau siv thev naus laus zis uas cuam tshuam nrog pneumatic sib cais, xws li huab cua classifier, txhawm rau faib cov khoom kom zoo. Kev faib tawm huab cua yog ib qho kev ua haujlwm uas cais cov khoom sib cais raws li lawv qhov sib txawv ntawm qhov loj, geometrical duab, thiab qhov ntom ntom hauv cov huab cua.
