Cov khoom

Nrog volcanic pob zeb basalt raws li lub ntsiab raw khoom, tom qab melted ntawm 1450 ℃ ~ 1500 ℃ thiab los ntawm platinum-rhodium alloy Kos duab los ntawm ib tug bushing ua nyob rau hauv high-ceev nws los ua tus nruam fiber ntau.

Basalt Fiber Reinforced Polymer Rebar (BFRP Rebar) yog ib hom tshiab ntawm cov khoom siv rebar ua los ntawm basalt fibers thiab resin matrix (xws li, epoxy resin) los ntawm cov txheej txheem pultrusion. Nws qhia tau hais tias tshwj xeeb zoo nyob rau hauv tej engineering teb raws li ib tug lwm txoj rau ib txwm steel rebar.

Basalt fiber yog ib yam khoom tsim los ntawm cov fibers zoo heev ntawm basalt, uas yog tsim los ntawm cov zaub mov plagioclase, pyroxene, thiab olivine. Nws zoo ib yam li cov pa roj carbon fiber ntau thiab fiberglass, muaj lub cev zoo dua qub dua li fiberglass, tab sis pheej yig dua li carbon fiber ntau. Nws yog siv los ua cov khoom siv hluav taws xob hluav taws xob hauv kev lag luam aerospace thiab automotive industries thiab tseem tuaj yeem siv los ua cov khoom sib xyaw los tsim cov khoom xws li lub koob yees duab tripods.

Chopped lev yog ib hom ntawv uas ua los ntawm basalt fiber uas yog txiav randomly thiab tusyees thiab ces khi ua ke nrog nplaum. Raws li cov ntaub ntawv sib txawv ntawm cov nplaum, nws tuaj yeem muab faib ua hmoov tws strand lev thiab emulsion tws strand lev.
Chopped strand lev cov khoom lag luam muaj cov yam ntxwv ntawm kev nkag mus nrawm nrawm, zoo pwm npog, kev tsim kho yooj yim, siab ntub dej tuav tus nqi, zoo lub teeb kis ntawm laminated board, tus nqi qis thiab lwm yam. Nws yog haum rau tes nteg.

Basalt Fiber Needled Mat yog ua los ntawm 100% basalt iav fibers nrog kub tsis kam mus txog 982 ° C (1800 ° F) thiab ua haujlwm kub ntawm 760 ° C (1400 ° F). Nws yog mechanically bonded los ntawm rab koob-punching txheej txheem siv cov tws fiber ntau ntev yam tsis muaj cov nplaum ntxiv. Ntau qhov me me yog tsim nyob rau hauv fiber ntau mats, muab cov khoom tsis tshua muaj siab thermal rwb thaiv tsev. Nyob rau tib lub sijhawm, basalt fibers tiv taus qhov kub thiab txias thiab muaj hluav taws xob zoo rwb thaiv tsev, nrog rau cov thermal rwb thaiv tsev zoo heev thiab zoo heev nqus suab hauv ntau daim ntawv thov.

Basalt fiber ntau tws strands yog ib hom luv-txiav cov khoom siv los ntawm basalt fibers, dav siv nyob rau hauv cov ntaub ntawv sib xyaw, qhob reinforcement, cov ntaub ntawv sib txhuam, thiab lwm yam.

Basalt fiber grid daim ntaub yog cov khoom siv txhawb zog ua los ntawm basalt fibers, dav siv hauv kev tsim kho, txoj kev, thiab choj engineering

Basalt fiber yarn, ua los ntawm cov pob zeb basalt, nws yog ib pawg ntawm cov kab sib txuas lossis ib txoj hlua ntawm cov hlua sib txuas uas tsis muaj kev sib tw, nws muaj peev xwm tiv taus qhov kub thiab txias txog li 1800F / 982C, Basalt fiber ntau yog los txhawb cov polymers (FRPs) thiab cov khoom sib xyaw ua ke, sib xyaw nrog vinyl resaturated thiab eps. phenolic resin, Nws muaj cov tshuaj zoo sib xws li iav fiber ntau tab sis muaj cov yam ntxwv zoo zog, siab modulus, muaj zog muaj zog, thiab kuj muaj zog tiv taus alkaline, acidic thiab ntsev tawm tsam ua rau nws yog ib tus neeg sib tw zoo rau cov pob zeb, choj thiab ntug dej hiav txwv.

Basalt twisted yarn yog cov xov paj uas ua los ntawm kev sib tw thiab ob npaug ntawm ib lossis ntau dua basalt fiber monofilament, txoj kab uas hla ntawm monofilament feem ntau yog ≤ 16 um. Twisted yarn tuaj yeem ua los ntawm ob, peb, plaub, lossis ntau dua plies, lossis siv tau ua ib leeg yam tsis muaj kev sib tw. Ib leeg thiab yarns yog siv los xaiv raws li lub hom phiaj. Basalt twisted yarn feem ntau tuaj yeem muab faib ua cov xov paj thiab lwm cov xov paj. Weaving yarn feem ntau yog ua los ntawm cov xov paj raj thiab lub raj mis zoo li lub raj xov paj.
