Cov choj hla dej hiav txwv, cov chaw nres nkoj dej tob, cov chaw ua cua ntsawj ntawm ntug dej hiav txwv ... Txawm hais tias cov "loj heev" uas tau tsim hauv dej hiav txwv zoo nkauj heev rau saib, lawv nyiaj dhau "kev tsim txom hnyav" txhua hnub ntawm kev yaig dej hiav txwv, kev xeb ntsev thiab alkali, thiab kev hloov pauv ntub-qhuav. Hauv ib puag ncig zoo li no, kev ua kom cov qauv pob zeb khov kho tseem zoo li qub - tsis muaj kev tawg, tawg, lossis kev puas tsuaj ua ntej lub sijhawm - tau ntev los ua qhov kev sib tw rau lub zej zog engineering thoob ntiaj teb.

Tau ntev lawm, cov hlau fibers feem ntau tau muab tso rau hauv cov pob zeb kom txhim kho kev tawv thiab tiv thaiv kev tawg. Txawm li cas los xij, cov hlau fibers feem ntau tsis haum rau cov xwm txheej hnyav ntawm cov ntsev tsuag thiab dej hiav txwv; thaum cov chloride ions nkag mus rau hauv cov kab nrib pleb hauv cov pob zeb, cov hlau fibers xeb thiab nthuav dav hauv qhov ntim, ua rau cov pob zeb tawg los ntawm sab hauv mus rau sab nraud thiab ua kom cov qauv tawg sai dua.
Tsis ntev los no, kev tshawb fawb tshiab txog cov khoom siv uas tsom mus rau kev ruaj khov rau kev tsim kho hauv dej hiav txwv tau muab ib qho kev daws teeb meem zoo heev: cov fibers basalt—uas tsim los ntawm kev rub cov xov los ntawm cov pob zeb volcanic ntuj—siv tau los ua cov pob zeb hauv dej hiav txwv hauv ib txheej "armor" uas tsis muaj xeb. Qhov no ua tiav los ntawm ntau qhov kev hloov pauv uas muaj kev sib xyaw ua ke ntawm "cov fibers loj rau kev sib txuas ntawm cov qauv" thiab "cov fibers me me rau kev kaw qhov hws."

Hauv kev lag luam ntawm cov ntaub ntawv txhawb nqa pob zeb, ib qho thev naus laus zis tshiab ua rau muaj kev hloov pauv loj hauv kev lag luam. Ib lub tuam txhab tsim khoom siv tshiab tsis ntev los no tau tshaj tawm tias nws cov khoom lag luam tshwj xeeb - ib qho fiber basalt zoo li pob khawm nrog lub cheeb ntawm 0.7 millimeters thiab ntev ntawm 12/35/50 millimeters - tau ua tiav kev tsim khoom lag luam. Nws yuav siv rau cov qauv pob zeb ua haujlwm siab, daws tau qhov teeb meem ntev ntev.

Cov fiber basalt, uas yog "cov fiber ntsuab ua tau zoo" uas tau los ntawm cov pob zeb basalt ntuj, muaj cov txiaj ntsig zoo xws li kev tiv taus kub siab, kev tiv taus tshuaj lom neeg, cov khoom siv kho tshuab zoo heev, thiab kev puas tsuaj rau ib puag ncig, ua rau muaj ntau yam khoom muaj nqis hauv kev lag luam textile. Ntawm cov no, cov xov paj tsis sib xyaw thiab cov ntaub tsis yog woven yog ob qho ntawm cov neeg sawv cev 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 nqa sib txawv hauv cov chaw 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.

Cov ntaub basalt fiber zoo tsim tshwj xeeb rau kev tsim cov epoxy resin laminates board. Nws siv cov fiber basalt txuas ntxiv mus los ntawm kev sib xyaw tshwj xeeb thiab cov txheej txheem kho kom zoo kom ua tiav qhov zoo tshaj plaws ntub thiab lo rau epoxy resin system, cov ntaub ntawv sib xyaw kawg nrog cov khoom siv kho tshuab zoo heev, tiv taus kub thiab tiv taus corrosion.

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.

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.

Tuam Tshoj Beihai Fiberglass zoo siab tshaj tawm tias nws koom nrog 7th International Composites Industry Exhibition (Eurasian Composites Show) ntawm Istanbul Expo Center, Turkey, txij lub Kaum Ib Hlis 26-28, 2025. Peb caw txhua tus neeg tuaj koom tuaj xyuas peb lub rooj muag khoom thiab tshawb nrhiav lub peev xwm loj ntawm peb cov ntaub ntawv fiberglass composite phenolic siab heev.

Cov fiber basalt, nrog rau cov basalt ntuj ua nws cov khoom siv raw, yog tsim los ua ib lub pob filament inorganic zoo tom qab kub siab yaj, kos duab, thiab kho cua sov. Cov fiber basalt muaj kev tiv thaiv kub siab, tiv thaiv oxidation, tiv thaiv hluav taws xob, rwb thaiv tsev thermal thiab acoustic, thiab kev ua haujlwm zoo heev. Vim tias nws cov txheej txheem tsim khoom yog huv thiab tsis muaj kuab paug, nws yog hu ua "cov khoom siv kev lag luam ntsuab xyoo pua 21st." Tom qab ntawd nws tau ua tiav ntxiv rau hauv cov khoom sib xyaw nrog daim ntawv ntawm rebar.

Kev faib cov fiber tsis sib npaug thaum lub sijhawm sib tov tuaj yeem ua rau lub zog ntawm cov mortar hauv zos, cuam tshuam rau nws qhov kev tiv thaiv tawg. Txhawm rau txhim kho kev faib cov fiber, cov khoom siv sib tov zoo yuav tsum tau siv thiab Lub sijhawm sib tov thiab qhov ceev yuav tsum tau kho kom haum kom ntseeg tau tias cov fiber sib npaug thoob plaws hauv cov mortar. Lub sijhawm sib tov kom raug pab kom ntseeg tau tias cov fibers tau sib xyaw ua ke nrog cov khoom siv cement; ob qho tib si ntev lossis luv luv lub sijhawm sib tov yuav cuam tshuam rau kev sib kis ntawm cov fiber thiab kev ua tau zoo ntawm cov mortar. Feem ntau nws raug pom zoo kom tswj lub sijhawm sib tov rau 3-5 feeb, zam kev sib xyaw ntau dhau, uas tuaj yeem ua rau cov fiber tawg thiab cuam tshuam tsis zoo rau qhov cuam tshuam ntawm kev txhawb nqa.
