Cov pob zeb basalt fiber siv cov qauv basalt fiber ntawm cov pob zeb, hauv kev sib tov pob zeb, thiab kev nchuav molding, tsis muaj kev cuam tshuam tsis zoo rau cov pob zeb, thiab tuaj yeem txhim kho kev sib koom ua ke thiab kev ruaj khov ntawm cov pob zeb; cov pob zeb sib xyaw nrog cov fiber basalt, txhim kho kev tiv thaiv kev cuam tshuam ntawm cov pob zeb, txo nws cov brittleness, tuaj yeem siv rau kev taug kev thiab cov phiaj xwm choj deck, tuaj yeem txhim kho cov khoom siv kho tshuab ntawm cov pob zeb; hauv cov pob zeb sib xyaw nrog cov fiber basalt, tuaj yeem txhim kho qhov tsis kam ntawm cov pob zeb, tiv taus kev khov thiab yaj voj voog thiab tiv taus shrinkage. Fiber hauv cov pob zeb tuaj yeem txhim kho qhov permeability ntawm cov pob zeb, tiv taus kev khov-thaw voj voog, thiab tiv taus shrinkage.

Basalt fiber yog cov fiber txuas ntxiv ua los ntawm cov pob zeb basalt ntuj ntshiab ua cov khoom siv raw, uas raug tsoo thiab ntxiv rau hauv lub qhov cub yaj, thiab tom qab ntawd yaj ntawm qhov kub siab ntawm 1450 ℃ ～ 1500 ℃, thiab tom qab ntawd rub ntawm qhov ceev ceev los ntawm platinum-rhodium alloy kos duab funnel phaj. Lub cheeb ntawm basalt fiber tsim los ntawm cov txheej txheem uas twb muaj lawm tuaj yeem yog txog li 6 ~ 13 μm, uas yog qhov zoo dua li cov plaub hau.

Cov pas nrig basalt fiber uas suav nrog lub cev pas nrig nuv ntses, lub cev pas nrig nuv ntses muaj tsawg kawg ib txheej ntawm cov txheej braided, ib qho ntawm cov txheej braided siv basalt fiber rau txoj kev tiaj tus lossis twill braided vim tias cov fiber basalt txuas ntxiv tsis yog tsuas yog muaj zog siab tab sis kuj muaj hluav taws xob rwb thaiv tsev, tiv taus corrosion, kub kub, thiab lwm yam kev ua tau zoo heev.

Hauv kev lag luam yas engineering uas tau hloov kho, cov khoom sib xyaw ua los ntawm cov fiber ntev yog cov khoom sib xyaw ua los ntawm cov fiber carbon ntev, cov fiber iav ntev, cov fiber aramid, lossis cov fiber basalt thiab cov polymer matrix los ntawm ntau txoj kev hloov kho tshwj xeeb. Qhov tshwj xeeb tshaj plaws ntawm cov khoom sib xyaw ua los ntawm cov fiber ntev yog tias lawv muaj kev ua tau zoo dua li cov khoom qub tsis muaj.

Basalt rebar yog ib yam khoom siv hloov pauv uas tau txais kev saib xyuas hauv kev lag luam kev tsim kho vim nws qhov ruaj khov thiab lub zog tshwj xeeb. Ua los ntawm basalt, qhov kev xaiv no rau cov hlau ib txwm muaj muab kev daws teeb meem zoo rau kev tsim kho cov qauv uas xav tau cov ntaub ntawv siv tau ntev thiab ruaj khov. Hauv cov blog no, peb yuav tshawb nrhiav qhov ruaj khov ntawm basalt rebar thiab teb cov lus nug hauv qab no: Lub neej ua haujlwm ntawm basalt rebar ntev npaum li cas?

Basalt fiber yog ib hom tshiab ntawm cov khoom siv fiber ntau uas tsis muaj zog thiab tsis ua rau ib puag ncig puas tsuaj, uas muaj silica, alumina, calcium oxide, magnesium oxide, hlau oxide thiab titanium dioxide thiab lwm yam oxides. Basalt fiber txuas ntxiv tsis yog tsuas yog muaj zog xwb, tab sis kuj muaj ntau yam khoom zoo heev xws li hluav taws xob rwb thaiv tsev, tiv taus corrosion, tiv taus kub thiab lwm yam.

Basalt fiber los ntawm cov txheej txheem warp knitting ua los ntawm mesh substrate, qhov kev kho saum npoo tuaj yeem ua los ntawm basalt fiber geogrid. Basalt geogrid feem ntau yog siv rau asphalt pavement reinforcement, reinforcing roadbed thiab mos av hauv paus.
