Basalt fiber tab tom hloov kho dua tshiab ntawm kev lag luam hluav taws kub

Basalttau faib dav dav thiab pheej yig hauv kuv lub tebchaws. Nws cov nqi tsim khoom fiber tsawg, thiab nws muaj cov txiaj ntsig zoo dua piv rau cov tshuaj fiber, carbon fiber, thiab Iav Fibers. Nws muaj peev xwm ua lag luam zoo heev thiab yog ib hom khoom siv thev naus laus zis siab tshiab, muaj nqis ntxiv rau lub caij nyoog tshiab.

Nyob rau hauv xyoo tas los no, cov ntaub ntawv ntsuab uas tiv taus hluav taws thiab cua sov tau maj mam tau txais kev saib xyuas. Cov fiber basalt, ua ib yam khoom siv uas zoo rau ib puag ncig, tau dhau los ua cov khoom siv zoo tshaj plaws rau kev tiv thaiv hluav taws thiab rwb thaiv cua sov, muaj cov yam ntxwv xws li lub teeb yuag, tiv taus hluav taws, rwb thaiv cua sov, thiab kev zoo nkauj. Basalt cov khoom siv fiber ntau uas tiv taus hluav taws thiab cua sov, muaj cov khoom sivbasalt fiber ntaub txheej, ib txheej roj hmab uas tiv taus kub heev, ib txheej polyester fiber film, ib txheej txhuas uas muaj pa dej tso rau, thiab ib txheej nplaum uas yooj yim hlawv thiab txheej ntaub Basof sib xyaw, qhia tau tias nws tiv taus hluav taws zoo heev thiab ua haujlwm tau zoo thaum kub heev. Hauv qhov chaw kub heev, nws tuaj yeem nqus tau qee qhov kub, ua rau nws rwb thaiv tsev kub zoo dua, thaum tseem tsis kub hnyiab, muab kev tiv thaiv zoo dua. Nws siv rau hauv kev tiv thaiv hluav taws, petrochemical, tub rog, thiab cov teb hlau.

Raws li Xibfwb Qi Fengjie ntawm College of Polymer Materials ntawm Northeastern University, daim ntaub tiv taus hluav taws ua los ntawm basalt fiber Nws ua rau nws tiv taus kub thiab rwb thaiv tsev tau zoo heev, nws tiv taus kub txog li 650 ℃ thiab nws cov pa oxygen index siab dua 68, zoo dua li cov organic fiber xws li aramid. Qhov no ua rau nws tsim nyog rau kev tsim cov ntaub thaiv hluav taws hauv kev lag luam. Basalt fiber fireproof ntaub yuav tsis ua kom tawg lossis tawg hauv qab nplaim taws 100 ℃, tswj nws qhov tiv taus hluav taws tau ntau tshaj ib teev. Nws kuj tseem muab kev tiv thaiv hauv qhov chaw noo noo, pa taws, pa luam yeeb, thiab cov tshuaj lom neeg uas yooj yim hlawv. Tsis tas li ntawd, kev sib xyaw cov fiber basalt nrog lwm cov fibers tuaj yeem tsim cov ntaub hluav taws kub dua, muab cov txiaj ntsig zoo rau cov khoom siv tub rog tshwj xeeb.

Tam sim no, nyob rau hauv kev ua lag luam thoob ntiaj teb, DuPont's Kevar, Nomex, thiab Tefon fibers yog cov khoom siv raw khoom nyiam rau cov ntaub fireproof. Txawm hais tias peb cov ntaub ntawv no muaj kev tiv taus kub thiab tshuaj lom neeg, lawv dhau los ua carbonization thiab decomposition ntawm qhov kub siab tshaj 370 ℃. Basalt fiber fireproof ntaub yog woven los ntawm tas mus li cov xov paj basalt ntawm 7um ~ 9umn los ntawm GBF Lub Tuam Txhab. Nws dhau los ntawm kev kho mob kub siab, tsis muaj tshuaj lom, tiv thaiv kev yaj thiab ntws, thermal shrinkage, thiab cov pa phem. Nws tuaj yeem ua haujlwm ua lwm txoj hauv kev zoo rau cov ntaub fiber tiv taus hluav taws xws li Kevlar, Nomex, thiab Teflon.

Kev tsim khoom ntawm basalt fiber nyuaj vim muaj kev cov nyom ntawm kev tsim cov xov paj thiab kev tswj cov txheej txheem, uas tau txwv txoj kev loj hlob ntawm cov ntaub ntawv siv cov fiber basalt. Tam sim no, tsuas yog ob peb lub tebchaws thoob ntiaj teb, suav nrog Russia, Ukraine, thiab kuv lub tebchaws, muaj cov thev naus laus zis no, nrog rau cov khoom tsim tawm thoob ntiaj teb tsawg dua 3,500 tons. Los ntawm kev tshawb nrhiav thiab kev xyaum ua haujlwm nyuaj, cov tuam txhab Suav tau kov yeej cov teeb meem kev siv tshuab hauv kev tsim cov fiber basalt thiab tau ua tiav kev tsim khoom loj, tsim kom muaj qee qhov kev lag luam.
