Daim Ntawv Thov thiab Kev Txhim Kho ntawm Basalt Untwisted Yarn thiab Basalt Nonwoven Fabric

Cov fiber basalt, ib qho "ntsuab high-performance fiber" uas tau los ntawm cov pob zeb basalt ntuj, muaj cov txiaj ntsig zoo xws li kev tiv taus kub siab, Tshuaj lom neeg kev tiv thaiv corrosion, cov khoom siv kho tshuab zoo heev, thiab kev puas tsuaj ib puag ncig, ua rau muaj kev txhim kho ntawm ntau yam khoom muaj nqis hauv kev lag luam textile. Ntawm cov no,cov xov paj tsis sib xws thiab cov ntaub tsis-woven yog ob tug neeg sawv cev uas siv dav tshaj plaws thiab muaj txiaj ntsig zoo tshaj plaws. Kev vam khom rau cov txheej txheem textile sib txawv thiab cov yam ntxwv ntawm cov qauv, lawv ua tiav kev txhawb zog sib txawv hauv cov cheeb tsam xws li kev txhawb nqa cov khoom siv sib xyaw ua ke zoo, kev tiv thaiv kev lag luam, thiab kev lim dej ib puag ncig.

Txawm hais tias cov xov paj tsis sib xws thiab cov ntaub tsis-woven txawv ntau heev hauv lawv cov txheej txheem thiab cov qauv, ob qho tib si siv cov txiaj ntsig ntuj ntawm basalt fiberkom ua tiav qhov tseem ceeb uas tsis muaj qhov hloov pauv tau hauv lawv cov teb. Los ntawm qhov kev xav tseem ceeb, ib qhoxov paj ntaub tsom mus rau kev txhawb nqa cov pob txha ntawm cov khoom sib xyaw thiab cov khoom siv ua haujlwm siab, thaum cov ntaub tsis yog woven tsom mus rau kev ua haujlwm thiab kev hloov pauv ntau qhov xwm txheej. Kev teeb tsa, cov xov paj tsis sib ntswg yog woven los ntawm cov filaments ntev, ua rau muaj cov qauv ntom thiab cov khoom siv kho tshuab anisotropic (nyob ntawm qhov weave), thaum cov ntaub tsis yog woven yog ua los ntawm cov txheej txheem luv luv lossis cov txheej txheem ntev nonwoven, ua rau muaj porosity siab thiab tso cai rau cov qauv isotropic lossis kev taw qhia txhawb nqa kom tsim raws li qhov yuav tsum tau ua. Hais txog cov txiaj ntsig tseem ceeb, cov xov paj tsis sib ntswg yog tus cwj pwm los ntawm kev khaws cia siab ntawm cov khoom siv kho tshuab thiab cov dej noo zoo, thaum cov ntaub tsis yog woven zoo tshaj plaws hauv nws cov qauv yooj ywm thiab ntau yam haujlwm xws li kev lim dej thiab kev nqus suab.

Ob leeg puav leej muaj qhov zoo sib txawv. Hais txog cov yam ntxwv ntawm ib puag ncig, ob qho khoom siv cov pob zeb basalt ntuj ua cov khoom siv raw thiab tuaj yeem lwj lossis hlawv yam tsis muaj cov pa roj phem tom qab pov tseg, ua raws li lub tswv yim ntawm kev txhim kho ntsuab. Hais txog kev ua tau zoo, ob qho tib si tau txais cov yam ntxwv tseem ceeb ntawm basalt fiber: tiv taus kub thiab qis, tiv taus corrosion, thiab ruaj khov kho tshuab. Hais txog kev hloov pauv tus nqi, lawv qhov sib piv tus nqi-kev ua tau zoo poob ntawm carbon fiber thiab iav fiber, muab qhov zoo dua tus nqi dua carbon fiber thiab kev ua tau zoo dua piv rau iav fiber, ua rau lawv hloov pauv tau dav rau ntau yam kev xav tau ntawm daim ntawv thov.

Yav tom ntej, nrog kev tshawb pom tshiab hauv kev siv tshuab ua kom cov fiber basalt pheej yig, kev siv tshuab sib xyaw ua ke ntawm ntau cov fiber (xws li cov xov paj basalt-carbon fiber sib xyaw), thiab cov txheej txheem txheej txheem ua haujlwm, ob hom khoom yuav hloov kho mus rau "tus nqi ntxiv siab" thiab "kev hloov kho tob rau ntau yam xwm txheej": Cov xov paj tsis sib txuas yuav nthuav dav mus rau thaj chaw xws li kev txhawb nqa cov khoom siv thauj khoom tseem ceeb hauv aerospace thiab cov khoom siv hluav taws xob zoo tshaj plaws; Cov ntaub tsis-woven yuav ua tiav "kev teb ntse" kev ua haujlwm hloov kho (xws li daim ntaub lim dej kub thiab daim ntaub tiv thaiv tus kheej), ntxiv rau cov xwm txheej meej xws li kev lim dej kho mob siab thiab cov roj teeb tshiab.

Raws li "tus neeg nqa khoom kawg" ntawm basalt fiber kev lag luam, kev siv thev naus laus zis ntawm cov xov paj tsis sib xws thiab cov ntaub tsis yog woven yuav txuas ntxiv tsav kev hloov pauv ntawm cov fiber basalt los ntawm "cov khoom siv pabcuam kev lag luam" mus rau "cov khoom siv ua haujlwm siab", muab kev txhawb nqa cov khoom siv tseem ceeb rau kev tsim khoom ntsuab, cov khoom siv siab thiab lwm yam teb.
