Cov khoom zoo ntawm Basalt Fibers

(1) Cov khoom siv txaus
Basalt fiber yog ua los ntawm basalt ore melted thiab kos, thiab cov reserves ntawm basalt ore nyob rau hauv lub ntiaj teb thiab lub hli yog lub hom phiaj heev, thiab tus nqi ntawm raw cov ntaub ntawv kuj yog tsawg.

(2) Environmentally-friendly cov ntaub ntawv
Basalt ore yog cov khoom siv ntuj tsim, thiab tsis muaj boron lossis lwm yam alkali hlau oxides tawm thaum nws cov txheej txheem tsim khoom, yog li tsis muaj nag lossis daus ntawm cov khoom tsis zoo hauv nws cov pa taws thiab plua plav, thiab nws yuav tsis ua kom muaj kuab paug rau huab cua. Ntxiv mus, cov khoom lag luam muaj lub neej ua haujlwm ntev, yog li nws yog hom tshiab ntawm cov khoom siv tiv thaiv ib puag ncig ntsuab nrog tus nqi qis, kev ua haujlwm siab thiab kev huv zoo tagnrho.

(3) Zoo heev kub tsis kam thiab thermal shock stability
Kev siv kub ntawm basalt fiber feem ntau yog -260-880 degree, uas yog siab dua li ntawm aramid fiber, alkali-dawb E iav fiber, asbestos, pob zeb ntaub plaub, stainless hlau, ze rau silicon fiber, aluminium silicate fiber thiab ceramic. fiber ntau, thiab thermal shock stability yog qhov zoo, uas tseem tsis hloov pauv ntawm 500 degree qhov kub thiab txias, thiab qhov hnyav qub tsuas yog poob 3% ntawm 900 degree.

(4) Zoo tshuaj stability
Cov kua qaub tsis kam thiab alkali tsis kam ntawm basalt fibers zoo dua li ntawm aluminosilicate fibers. Nws cov kav ntev, huab cua tsis kam, ultraviolet hluav taws xob tiv thaiv, dej tsis kam, oxidation tsis kam thiab lwm yam khoom zoo sib xws rau ntuj basalt hau.

(5) Siab elastic modulus thiab tensile lub zog
Lub elastic modulus ntawm basalt fiber ntau yog 9100 kg/mm?--11000 kg/mm?, uas yog siab dua li ntawm alkali-dawb iav fiber, asbestos, aramid fiber, polypropylene fiber thiab silicon fiber. Lub zog tensile ntawm basalt fiber ntau yog 3800-4800 MPa, uas yog siab dua li cov cab loj carbon fiber, aramid, PBI fiber, steel fiber, boron fiber thiab alumina fiber, thiab yog piv rau S iav fiber.

(6) Lub suab nqus coefficient yog siab
Lub suab nqus coefficient ntawm basalt fiber ntau yog 0.9-0.99, uas yog siab dua li ntawm alkali-dawb iav fiber ntau thiab silicon fiber ntau. Kev xa tawm nthwv dej zoo heev thiab qee qhov nthwv dej nqus, zoo heev lub suab nqus thiab suab rwb thaiv tsev kev ua tau zoo, kev ua haujlwm zoo stealth, tuaj yeem ua rau hauv cov ntaub ntawv stealth.

(7) Zoo hluav taws xob rwb thaiv tsev thiab dielectric zog
Qhov tshwj xeeb ntim tsis kam ntawm basalt fiber ntau yog 1 × 10 ^ 12Ω·m, uas yog siab dua li ntawm alkali-dawb iav fiber ntau thiab silicon fiber, thiab lub ntim resistivity yog ib qho kev txiav txim siab ntau dua li cov hluav taws xob insulating E iav fiber ntau. , thiab dielectric poob tangent yog 50% siab dua.

(8) Ntuj silicate compatibility
Nws muaj zoo dispersion nrog cov cement thiab pob zeb, muaj zog adhesion, zoo ib yam thermal expansion thiab contraction coefficient, thiab huab cua tsis zoo.

(9) Tsawg noo noo nqus
Kev nqus dej ntawm basalt fibers tsawg dua 0.1%, uas yog qis dua li ntawm aramid fibers, pob zeb ntaub plaub thiab asbestos.
