Cov ntaub basalt fiber nonwoven yog cov ntaub ntawv ua los ntawm kev tso cov fiber 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 lub ntsiab lus tseem ceeb yog nws "kev tswj hwm cov qauv" thiab "kev ua haujlwm ntau yam." Los ntawm kev kho qhov ntev ntawm cov fiber, txoj kev tso web, thiab cov txheej txheem txhawb nqa, nws cov khoom siv lub cev thiab tshuaj lom neeg tuaj yeem hloov kho kom haum rau ntau qhov xwm txheej sib txawv.

Basalt fiber untwisted Cloth yog ib daim ntaub nyias nyias uas ua los ntawm cov basalt fiber filaments (untwisted lossis weakly twisted) siv cov qauv weave yooj yim xws li tiaj tus thiab twill. Nws lub ntsiab lus tseem ceeb yog nyob rau hauv kev ua kom zoo tshaj plaws ntawm cov khoom siv kho tshuab thiab kev ua haujlwm ntawm basalt fibers los ntawm kev tsim qauv ntawm "low twist + high continuity," ua rau nws yog ib qho zoo tagnrho reinforcing substrate hauv thaj teb ntawm cov ntaub ntawv sib xyaw.

Cov khoom siv fiber basalt muaj kev siv zoo heev. Yog li, basalt fiber tsim tawm li cas? Nws yog cov fiber txuas ntxiv ua los ntawm kev rub cov pob zeb basalt sai sai tom qab yaj ntawm 1450 ° C txog 1500 ° C los ntawm platinum-rhodium alloy spinneret. Basalt fiber yog xim av lossis kub. Basalt fiber yog ib hom tshiab ntawm cov khoom siv inorganic, tus phooj ywg ib puag ncig, ntsuab, ua haujlwm siab fiber. Nws yog cov khoom siv tshiab rau xyoo pua 21st uas yog ntsuab, tus phooj ywg ib puag ncig, thiab tsis ua rau muaj kuab paug, thiab nws yog ib qho ntawm plaub lub fibers ua haujlwm siab loj hauv Suav teb. Basalt fiber qhia txog cov khoom zoo heev hauv kev muaj zog, tiv taus qhov kub siab thiab qis, tiv taus corrosion, rwb thaiv tsev thermal, rwb thaiv tsev suab, hluav taws kub retardancy, nrog rau tshuaj lom neeg thiab hluav taws xob rwb thaiv tsev.

Daim ntawv tshawb fawb hu ua "Hierarchical basalt metayarn rau ergonomic tiv thaiv qhov chaw textiles" tau luam tawm hauv phau ntawv xov xwm Matter los ntawm pab pawg ntawm Xibfwb Xia Zhigang thiab Academician Xu Weilin los ntawm National Key Laboratory of New Textile Materials and Advanced Processing ntawm Wuhan Textile University, koom tes nrog Xibfwb Tao Guangming.

Cov fiber basalt tsis yog tsuas yog muaj lub zog siab, kev ruaj khov thermal zoo, kev tiv thaiv kev puas tsuaj rau cov neeg sib tw, kev hnav tsawg, thiab kev sib txhuam ruaj khov, tab sis kuj los ntawm tus nqi tsim nyog. Kev siv cov fiber basalt hauv cov ntaub ntawv txhim kho kev sib txhuam yog qhov zoo rau ob qho tib si ua kom lub neej ntawm cov ntaub ntawv sib txhuam hauv tsheb thiab txhim kho lawv qhov kub ua haujlwm. Nws kuj tseem tuaj yeem daws ntau yam teeb meem uas twb muaj lawm ntawm cov ntaub ntawv sib txhuam tam sim no, uas pab daws qhov teeb meem thermal fading hauv cov nres tsheb ib txwm muaj, yog li txo qhov tshwm sim ntawm kev sib tsoo tsheb.

Cov Khoom Siv Basalt Fiber Reinforced Plastics (BFRP) tab tom tshwm sim los ua lwm txoj hauv kev zoo rau cov khoom siv ib txwm muaj, muab kev sib xyaw ua ke ntawm kev ruaj khov, kev ua haujlwm siab, thiab kev siv nyiaj tsim nyog. Los ntawm pob zeb volcanic, cov fibers basalt muaj cov khoom siv kho tshuab zoo heev, kev ruaj khov tshuaj lom neeg zoo heev, thiab kev phooj ywg ib puag ncig. Cov yam ntxwv no tso BFRP ua qhov kev hloov pauv rau cov lag luam tseem ceeb, tshwj xeeb tshaj yog cov uas muab qhov tseem ceeb rau cov qauv sib dua, kev ruaj khov, thiab kev tiv taus rau ib puag ncig hnyav.

Qhov chaw ua yeeb yam ntawm Eurasian Composites Qhia nyob rau hauv Istanbul, Qaib ntxhw, tau hloov ntawm Hall 6, Booth B540 mus rau Hall 5, Booth B540.

Acid-base etched basalt fiber yog cov khoom siv basalt fiber tshwj xeeb uas muaj cov khoom siv lub cev thiab tshuaj lom neeg tshwj xeeb.

Cov fiber basalt yog cov khoom siv fiber inorganic ua los ntawm cov pob zeb basalt ntuj, uas yaj ntawm qhov kub siab thiab tom qab ntawd rub mus rau hauv cov fibers. Nws yog cov khoom siv fibers ua tau zoo, zoo ib yam li cov iav fiber thiab carbon fiber, tab sis txawv ntawm cov khoom siv raw, cov txheej txheem tsim khoom, thiab qee yam kev ua tau zoo. Cov hauv qab no tshuaj xyuas cov thev naus laus zis basalt fiber hla ntau qhov ntev.

Nyob rau hauv xyoo tas los no, Kev tsim kho txoj kev loj hauv Suav teb tau tsim kho sai heev, thiab cov thev naus laus zis ntawm cov qauv pob zeb tau ua tiav kev vam meej tseem ceeb, sib sau ua ke ntau yam siab heev thiab levkev ua tiav ntawm cov txuj ci kev txawj ntse. Kev tsim qauv pob zeb tau siv dav hauv kev tsim kho vaj tse, qhia txog nws qhov tseem ceeb. Txawm li cas los xij, nrog rau cov kev ua tiav no, qhov teeb meem ntawm kev tawg pob zeb tau dhau los ua qhov tseem ceeb. Qhov muaj cov kab nrib pleb ua rau kev ua haujlwm ntawm pob zeb puas tsuaj, tshwj xeeb tshaj yog txo nws lub zog tensile, uas yog thawj qhov rqhov ua rau muaj kev tawg yooj yim uas pom los ntawm cov pob zeb ua vaj tse. Cov fiber basalt luv luv, ua ib yam khoom siv fiber tshiab, tau dhau los ua cov khoom siv txhim kho pob zeb zoo heev vim nws cov khoom siv kho tshuab tshwj xeeb, kev ruaj khov zoo, thiab kev siv nyiaj tsim nyog. Tsab xov xwm no yuav tsom mus rau cov yam ntxwv ntawm cov fiber basalt luv luv thiab tshawb nrhiav nws cov kev siv hauv kev txhawb nqa thiab ua kom muaj zog.
