Basalt fiber raw khoom xaiv thiab ua

Nyob rau hauv lub evolutionary txheej txheem ntev ntawm lub ntiaj teb, basalt, raws li ib tug tseem ceeb natural resources, nws cim genesis thiab dav faib ua rau nws ib tug zoo tagnrho raw khoom rau kev tsim high-kev ua tau zoo. Basalt Fiber ntaus. Hauv daim ntawv no, peb yuav tham txog cov yam ntxwv, kev xaiv thiab txheej txheem kev kho mob ntawm basalt.

Properties ntawm basalt

Basaltyog tsim los ntawm kev ua kom txias sai thiab khov ntawm magma los ntawm volcanic eruptions, thiab nws cov khoom tseem ceeb muaj xws li silica (SiO₂), aluminium oxide (Al₂O₃), hlau oxide (Fe₂O₃), calcium oxide (CaO) thiab magnesium oxide (MgO). Feem ntau dub lossis tsaus grey hauv qhov tsos, nws muaj lub cev zoo heev thiab Tshuaj cov khoom thiab tau nthuav dav thoob plaws ntiaj teb, suav nrog Hawaii, Iceland, thiab ntau thaj chaw ntawm Tuam Tshoj.

Cov txheej txheem rau kev xaiv cov khoom siv raw

Kev tsim cov khoom zoo basalt fibers nyob ntawm cov khoom siv raw uas ua tau raws li cov kev cai tshwj xeeb:

Tshuaj muaj pes tsawg leeg:

Silicon Dioxide: Cov ntsiab lus yuav tsum nyob nruab nrab ntawm 45% -55% kom paub meej viscosity thiab fluidity thaum lub sij hawm melting txheej txheem.

Aluminium oxide: Feem ntau ntawm 12% -16% txhawm rau txhim kho qhov kub thiab txias.

Calcium oxide thiab magnesium oxide: 8% -12% calcium oxide thiab 6% -10% magnesium oxide yog siv los tswj cov khoom yaj.

Hlau oxide: tsis ntau tshaj 10%, tus nqi nruab nrab tuaj yeem siv ua flux.

Lub cev muaj zog:

Uniform thiab ntom qauv: txo qhov hauv qhov thiab cov kab nrib pleb thiab ua kom zoo ib yam muaj pes tsawg leeg thiab kub thaum lub sij hawm melting.

Nruab nrab hardness: yooj yim rau kev ua tiav rau hauv qhov loj me me, tsis txhob muaj teeb meem ntawm kev nyuaj siab lossis softness.

Melting point ntau yam: Qhov tsim nyog melting point yuav tsum nyob nruab nrab ntawm 1450 ℃ - 1550 ℃ kom ntseeg tau tias tag nrho melting.

Purity xav tau:High purity basalt yog lub hauv paus rau kev tsim cov fibers zoo, uas yuav tsum tau tshem tawm cov teeb meem impurities xws li sulfur thiab phosphorus.

Cov txheej txheem kho cov khoom nyoos

Txhawm rau kom ntseeg tau qhov zoo ntawm basalt fibers, cov txheej txheem kev kho mob yog qhov tseem ceeb:

Raw khoom pretreatment: sorting thiab tshem tawm impurities los xyuas kom meej lub purity ntawm raw cov ntaub ntawv.

Crushing thiab milling: crushing loj basalt rau hauv me me hais rau tom ntej ua.

Mixing thiab blending: siv high-pressure gas suspension mixing los xyuas kom meej tias cov hmoov yog tag nrho intermingled.

Homogenization: Txhim kho qhov sib xws ntawm raw cov ntaub ntawv los ntawm homogenization kom ruaj khov tshuaj muaj pes tsawg leeg thiab cov yam ntxwv melting.

Kub-kub melting: Kub-kub melting thiab stirring nyob rau hauv lub cub tawg kom ua tau ib tug high degree ntawm homogenization.

Xaus

Basalt, raws li ib tug nplua nuj natural resources, yog ib qho tseem ceeb raw khoom rau kev tsim khoom ntawm high-kev ua tau zoo basalt fibers. Los ntawm nruj raw khoom xaiv thiab txheej txheem kev kho mob, nws tuaj yeem ua kom muaj cov khoom zoo basalt fibers, uas tau siv dav hauv ntau lub teb, xws li aerospace, kev tsim kho, thiab tsheb. Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, basalt thiab nws cov ntaub ntawv fiber ntau yuav ua lub luag haujlwm tseem ceeb hauv ntau thaj chaw thiab txhawb kev nce qib thiab kev loj hlob ntawm tib neeg. Yog li ntawd, kev tsim kho thiab kev siv cov khoom muaj nqis ntuj no yuav ua rau muaj txiaj ntsig ntau dua rau noob neej.
