Cov Ntaub Basalt Fiber Tsis Woven: Ib qho Multi-Scenario "Kev Tiv Thaiv Kev Ua Haujlwm" thiab "Kev Dais Teeb Meem Zoo Rau Ib Puag Ncig"

Basalt fiber tsis woven ntaubyog ib daim ntawv khoom ua los ntawm kev tso cov fibers basalt lossis cov filaments txuas ntxiv mus rau hauv lub web thiab tom qab ntawd txhawb nqa nws los ntawm cov txheej txheem tsis yog woven xws li koob punching, hydroentangling, thiab meltblowing (uas xav tau ntxiv me ntsis ntawm cov fibers kub-yaj). Nws cov txiaj ntsig tseem ceeb nyob rau hauv nws "kev tswj hwm cov qauv" thiab "kev ua haujlwm versatility." Los ntawm kev kho qhov ntev ntawm cov fiber, txoj kev tso web, thiab cov txheej txheem txhawb nqa, nws lub cev thiab Tshuaj lom neeg cov khoom tuaj yeem hloov kho kom haum rau ntau yam xwm txheej. Cov ntaub basalt fiber nonwoven yog ib lo lus dav dav. Piv txwv li, peb lub tuam txhabCov Ntaub Soj Ntsuam Basalt Fiber Surfacing thiab Basalt Fiber Needled Mat ob qho tib si poob rau hauv pawg no.

1. Cov Yam Ntxwv Tseem Ceeb: Cov Txiaj Ntsig Tseem Ceeb ntawm Cov Qauv Yooj Yim thiab Cov Haujlwm Sib Txawv

Cov Qauv thiab Qhov Thickness Kho Tau: Txij li daim ntaub lim nyias (0.1 hli) mus rau cov paj rwb tuab uas nqus suab (50 hli), tus lej thiab qhov ceev ntawm cov txheej web tuaj yeem tswj tau meej; kev faib cov fiber ntau ua rau cov khoom siv "isotropic," thaum kev tso web uas taw qhia tuaj yeem txhim kho cov khoom siv kho tshuab hauv cov lus qhia tshwj xeeb. Kev ua haujlwm lim zoo heev: Lub fiber txoj kab uas hla yog qhov zoo (txog li 5 ~ 10μm) thiab qhov porosity siab (txog li 70% ~ 90%), nrog rau kev ua haujlwm khaws cov hmoov av thiab cov khoom me me ntawm ntau dua 99% (PM2.5 kev ua haujlwm lim ≥95%), thiab tsis tshua muaj cua tsis kam.

Kev tiv thaiv ib puag ncig thiab kev nyab xeeb: Cov khoom siv raw yog basalt ntuj, tsis muaj kev tso tawm cov tshuaj lom xws li formaldehyde thiab benzene; nws tuaj yeem raug rhuav tshem lossis hlawv tom qab pov tseg (kev hlawv tsis tso cov pa phem, thiab cov seem yog inorganic oxides), ua tau raws li qhov yuav tsum tau ua ntawm "kev tsim khoom ntsuab".

Kev koom ua ke ntau yam: Los ntawm cov txheej txheem sib xyaw (xws li sib xyaw nrog carbon fiber thiab Iav Fiber) lossis kev kho mob txheej (xws li cov txheej tiv thaiv dej thiab cov txheej tiv thaiv kab mob), nws tuaj yeem ua tiav kev sib koom ua ke ntau yam xws li "lim + rwb thaiv tshav kub" thiab "kev tiv thaiv + ua pa tau".

2. Tus nqi siv tseem ceeb: Txij li kev lim dej hauv kev lag luam mus rau kev tiv thaiv pej xeem

(1) Kev lim dej hauv kev lag luam: Lub "core medium" rau kev ua kom huv si zoo

Cov ntaub basalt fiber nonwoven tau dhau los ua cov khoom siv zoo tshaj plaws rau kev lim dej hauv qab qhov xwm txheej ua haujlwm hnyav vim nws tiv taus qhov kub thiab txias siab thiab tshuaj lom neeg xeb. Hauv kev lim roj flue kub siab, cov khoom siv lim dej baghouse siv hauv kev lag luam xws li hlau, cement, thiab kev hlawv pov tseg tuaj yeem lim cov hmoov av thiab cov khoom me me (xws li cov dioxin carriers) hauv cov roj flue rau lub sijhawm ntev ntawm qhov kub ntawm 200-400 ℃, nrog lub neej ua haujlwm ntev dua 3-5 npaug dua li cov khoom siv lim polyester ib txwm muaj. Hauv kev lim kua, ua daim ntaub lim dej meej hauv kev lag luam tshuaj lom neeg thiab electroplating, nws tuaj yeem lim cov khoom tsis huv hauv cov kua qaub thiab alkaline yam tsis muaj tshuaj lom neeg cuam tshuam nrog cov khoom nruab nrab, ua tiav qhov tseeb ntawm 1-5μm.

(2) Kev Tiv Thaiv thiab Kev Tiv Thaiv Ib puag ncig: Ib "Kev Lav Xias Ob Zaug" ntawm Kev Nyab Xeeb thiab Kev Ntsuab

Hauv kev siv cov khoom siv tiv thaiv tus kheej, nws yog siv los tsim cov ntaub npog plua plav, cov ntaub npog vuam, thiab cov txheej rwb thaiv tsev kub rau cov khaub ncaws tua hluav taws, ua ke ua pa tau zoo thiab tiv thaiv - piv rau cov ntaub tsis yog ntaub uas yaj, nws muaj zog tiv taus kub, ua rau nws tsim nyog rau kev ua haujlwm kub siab xws li vuam thiab tua hluav taws, thiab nws tsis muaj kev pheej hmoo ntawm kev sib sau ua ke ntawm hluav taws xob zoo li qub, ua rau nws tsim nyog rau cov chaw kub hnyiab thiab tawg. Hauv kev tiv thaiv ib puag ncig thiab kev kho dua tshiab ntawm ecological, ua lub geomembrane liner rau kev kho av thiab cov nroj tsuag loj hlob rau kev tiv thaiv ecological ntug dej, nws cov kua qaub thiab alkali tsis kam thiab cov khoom tiv thaiv biodegradation ua kom muaj kev ruaj khov ntev thaum tso cai rau dej thiab cov as-ham kom nkag mus, yog li pab txhawb rau kev kho dua tshiab ntawm ib puag ncig.

(3) Cov ntaub ntawv siv tau rau kev tsim kho: "Kev ua kom zoo dua qhov xwm txheej" rau kev nplij siab thiab kev txuag hluav taws xob

Hais txog cov ntaub ntawv uas nqus suab thiab txo suab nrov, cov ntaub tuab uas tsis yog woven uas siv koob punched yog siv los ua txheej uas nqus suab nrov rau kev tsim cov phab ntsa sab hauv, cov qhov chaw nqa khoom, thiab cov qhov av tsheb ciav hlau. Los ntawm kev cuam tshuam thiab kev cuam tshuam ntawm cov suab nrov los ntawm cov qhov fiber, nws tuaj yeem txo suab nrov los ntawm 15 ~ 25dB. Nws kuj tiv taus qhov kub siab thiab tsis kub hnyiab (oxygen index ≥40%, uas yog cov khoom siv uas tsis kub hnyiab). Hais txog cov ntaub ntawv rwb thaiv tsev thermal, nws yog siv rau kev tsim cov txheej rwb thaiv tsev phab ntsa sab nraud thiab cov tes tsho rwb thaiv tsev rau cov khoom siv hauv kev lag luam. Nws muaj cov thermal conductivity qis (≤0.038W / (m·K)) thiab tsis nqus dej noo lossis muaj kev pheej hmoo ntawm kev loj hlob ntawm pwm, uas zoo dua li cov ntaub ntawv rwb thaiv tsev pob zeb ib txwm muaj.
