Kev Piav Qhia Luv:

Sepiolite fiber yog ib qho mineral magnesium silicate ntuj uas muaj cov qauv saw hlau sib txawv. Cov qauv no tsim ntau lub qhov me me thiab cov channel sib txuas, uas ua rau sepiolite fiber zoo kawg nkaus lub cev thiab tshuaj lom neeg. Tsis zoo li ntau cov khoom siv hluavtaws, sepiolite fiber muaj nyob hauv av, feem ntau pom hauv cov av nplaum, thiab tsuas yog xav tau kev ntxuav thiab kev ua kom zoo kom qhib nws cov haujlwm ntau yam. Nws qhov tsos zoo li cov koob me me uas tuaj yeem tawg mus rau hauv cov fibers ib leeg hauv cov kuab tshuaj polar, tsim cov tes hauj lwm sib txuas uas txhim kho kev ua tau zoo ntawm ntau yam khoom.

Qhov zoo ntawm cov fiber sepiolite yog nws lub peev xwm adsorption zoo heev, los ntawm thaj chaw siab thiab cov pab pawg hydroxyl ntau ntawm cov fiber nto. Cov pab pawg hydroxyl no tuaj yeem tsim cov hydrogen bonds nrog cov tshuaj sib txawv, thaum ntau theem pore qauv - suav nrog cov channel me me sab hauv thiab cov qhov loj dua ntawm cov fiber - ua rau kev ntes cov khoom tsis huv. Hauv kev kho dej khib nyiab hauv kev lag luam, lub peev xwm adsorption no muaj txiaj ntsig tshwj xeeb. Sepiolite fiber tuaj yeem tsom mus rau cov hlau hnyav ions, cov xim organic, phenols thiab cov roj hauv cov dej khib nyiab, ntes lawv hauv nws cov qauv pore los ntawm kev nqus lub cev thiab tshuaj lom neeg.

Kev siv rau hauv kev kho dej khib nyiab hauv kev lag luam qhia tau tias muaj txiaj ntsig zoo ntawm cov sepiolite fiber. Thaum ntxiv rau hauv cov thoob dej tshuaj lossis siv ua cov lim dej hauv cov kem, nws txo cov pa phem. Cov sepiolite fiber hloov kho, kho nrog cov kua qaub kom nthuav qhov loj me thiab tshem tawm cov khoom tsis huv, qhia txog kev ua haujlwm adsorption zoo dua. Tom qab adsorption saturation, sepiolite fiber tuaj yeem rov ua dua los ntawm cov txheej txheem yooj yim xws li elution nrog cov tshuaj ntsev lossis cua sov, tso cai rau kev siv dua thiab txo cov khib nyiab. Qhov kev rov ua dua tshiab no ua rau nws yog qhov kev xaiv pheej yig rau kev kho dej khib nyiab mus sij hawm ntev, tshwj xeeb tshaj yog rau cov chaw tsim khoom me me thiab nruab nrab.

Kev lag luam khoom siv hauv tsev yog lwm qhov chaw tseem ceeb uas cov fiber sepiolite ua tau zoo tshaj plaws, feem ntau yog los ntawm kev txhim kho cov qauv thiab kev ua haujlwm zoo tshaj plaws. Thaum sib xyaw rau hauv cov cement mortar lossis gypsum cov khoom, cov fibers nyias nyias ntawm sepiolite tsim cov tes hauj lwm txhawb nqa peb sab hauv matrix. Cov tes hauj lwm no thaiv kev tsim thiab nthuav dav ntawm cov kab nrib pleb me me, txhim kho lub zog kho tshuab - suav nrog lub zog compressive thiab flexural - ntawm cov ntaub ntawv tsim kho. Rau cement mortar, ntxiv cov sepiolite fiber kom tsim nyog tuaj yeem ua rau lub zog flexural ntau dua nees nkaum tsib feem pua. Tsis tas li ntawd, sepiolite fiber tswj cov dej noo hauv cov ntaub ntawv tsim kho; nws nqus cov dej noo ntau dhau hauv cov chaw noo noo thiab tso nws tawm hauv cov xwm txheej qhuav, txo qhov kev hloov pauv los ntawm kev hloov pauv ntawm cov dej noo.

Hauv cov txheej txheej thiab cov ntaub ntawv rwb thaiv tsev, sepiolite fiber muab ntau yam txiaj ntsig. Hauv cov txheej txheem vaj tse raws li dej, nws cov qauv fiber tsim cov tes hauj lwm thixotropic uas tiv thaiv kev sagging thaum lub sijhawm thov thaum tswj kev du thaum txhuam. Cov qauv no kuj tiv thaiv kev sib sau ua ke ntawm cov xim thiab cov khoom sau, txuas ntxiv kev ruaj khov ntawm cov txheej txheej. Rau cov khoom siv rwb thaiv tsev, qhov xwm txheej ntawm sepiolite fiber txo cov thermal conductivity, txhim kho cov txiaj ntsig khaws cia kub, thaum nws cov pob txha fiber tiv thaiv cov hmoov ntawm cov txheej rwb thaiv tsev, sib npaug kev ua haujlwm rwb thaiv tsev thiab lub zog kho tshuab. Cov txheej txheem hluav taws kub kuj tau txais txiaj ntsig los ntawm sepiolite fiber qhov kub siab tiv thaiv, txuas ntxiv lub sijhawm tiv thaiv hluav taws ntawm cov txheej txheej.

Kev ntxuav huab cua yog lwm qhov chaw siv tseem ceeb rau sepiolite fiber. Nws lub peev xwm adsorption zoo ntes cov pa phem thiab cov khoom me me hauv huab cua. Thaum ua rau hauv cov ntxaij lim dej lossis ua ke nrog lwm cov ntaub ntawv hauv cov khoom ntxuav, nws tshem tawm cov organic sib xyaw thiab formaldehyde los ntawm huab cua sab hauv tsev. Sepiolite fiber kuj ua haujlwm ua tus cab kuj catalyst; thauj cov hlau oxides lossis photocatalysts rau ntawm nws qhov chaw ua rau catalytic hloov pauv ntawm cov tshuaj phem mus rau hauv cov tsis muaj kev phom sij. Qhov kev sib xyaw ua ke ntawm adsorption thiab catalysis ua rau sepiolite fiber raws li cov ntaub ntawv ntau dua hauv kev ntxuav huab cua, zam cov teeb meem kev ua qias tuaj thib ob uas cuam tshuam nrog qee cov adsorbents.

Kev ua tau ntau yam ntawm sepiolite fiber yog los ntawm kev sib koom ua ke ntawm nws cov qauv ntuj thiab cov khoom hloov kho tau. Nws qhov sib xws nrog lwm cov ntaub ntawv tso cai rau kev sib xyaw nrog cov resins, av nplaum thiab cov catalysts los tsim cov khoom lag luam rau cov kev xav tau tshwj xeeb. Txawm hais tias nyob rau hauv kev tiv thaiv ib puag ncig, kev tsim kho lossis kev kho cua, sepiolite fiber ua lub luag haujlwm ntawm kev ua haujlwm zoo dua, adsorbent lossis stabilizer. Raws li kev tshawb fawb ntawm kev hloov kho thev naus laus zis nce qib, cov ntawv thov ntawm sepiolite fiber txuas ntxiv nthuav dav, los ntawm cov ntaub ntawv kub kub mus rau cov khoom siv hluav taws xob tshiab. Cov fiber ntuj no, nrog nws cov txiaj ntsig kev ua tau zoo thiab kev phooj ywg ib puag ncig, tseem yog cov khoom muaj nqis thoob plaws ntau lub lag luam.
