Kev xaiv thiab ua cov khoom siv basalt fiber ntau
Hauv cov txheej txheem ntev ntawm lub ntiaj teb, basalt, ua ib qho khoom siv tseem ceeb ntawm ntuj tsim, nws lub hauv paus chiv keeb thiab kev faib tawm dav dav ua rau nws yog cov khoom siv raw zoo tshaj plaws rau kev tsim cov khoom siv ua haujlwm siab. Basalt Fibers. Hauv tsab ntawv no, peb yuav tham txog cov yam ntxwv, cov qauv xaiv thiab cov txheej txheem kho ntawm basalt.
Cov khoom ntawm basalt
Basaltyog tsim los ntawm kev txias thiab khov sai ntawm magma los ntawm kev tawg roob hluav taws, thiab nws cov khoom tseem ceeb suav nrog silica (SiO₂), txhuas oxide (Al₂O₃), hlau oxide (Fe₂O₃), calcium oxide (CaO) thiab magnesium oxide (MgO). Feem ntau dub lossis grey tsaus nti hauv qhov tsos, nws muaj lub cev zoo heev thiab Tshuaj lom neeg cov khoom thiab tau faib dav thoob plaws ntiaj teb, suav nrog Hawaii, Iceland, thiab ntau thaj chaw ntawm Suav teb.
Cov txheej txheem rau kev xaiv cov khoom siv raw
Kev tsim cov fibers basalt zoo nyob ntawm cov khoom siv raw uas ua tau raws li cov kev cai tshwj xeeb:
Cov tshuaj lom neeg muaj pes tsawg leeg:
Silicon Dioxide: cov ntsiab lus yuav tsum nyob nruab nrab ntawm 45% -55% kom ntseeg tau tias muaj viscosity thiab fluidity thaum lub sijhawm yaj.
Aluminium oxide: feem ntau ntawm 12% -16% los txhim kho kev tiv taus kub siab.
Calcium oxide thiab magnesium oxide: 8% -12% calcium oxide thiab 6% -10% magnesium oxide yog siv los tswj cov khoom yaj.
Hlau oxide: tsis pub ntau tshaj 10%, qhov nruab nrab tuaj yeem siv ua flux.
Cov khoom siv lub cev:
Cov qauv sib xws thiab ntom ntom: txo cov qhov thiab cov kab nrib pleb sab hauv thiab ua kom muaj kev sib xyaw thiab qhov kub thaum lub sijhawm yaj.
Nruab nrab hardness: yooj yim kom ua tiav rau hauv qhov loj me me, zam qhov teeb meem ntawm qhov nyuaj lossis mos muag ntau dhau.
Qhov ntau ntawm cov ntsiab lus yaj: Qhov chaw yaj uas tsim nyog yuav tsum nyob nruab nrab ntawm 1450 ℃ -1550 ℃ kom ntseeg tau tias yaj tag nrho.
Cov kev cai ntawm kev huv huv:Basalt purity siab yog lub hauv paus rau kev tsim cov fibers zoo, uas xav tau kev tshem tawm cov khoom tsis zoo xws li sulfur thiab phosphorus.
Cov txheej txheem kho cov khoom siv raw
Yuav kom ntseeg tau tias qhov zoo ntawm cov fibers basalt, ntau cov txheej txheem kho mob yog qhov tseem ceeb:
Kev kho ua ntej ntawm cov khoom siv raw: kev txheeb xyuas thiab tshem tawm cov khoom tsis huv kom ntseeg tau tias cov khoom siv raw purity.
Kev sib tsoo thiab milling: crushing loj basalt rau hauv cov khoom me me rau kev ua tiav tom ntej.
Kev sib xyaw thiab kev sib xyaw: siv cov roj siab siab sib tov kom ntseeg tau tias cov hmoov sib xyaw ua ke tag nrho.
Kev Sib Koom Ua Ke: Txhim kho qhov sib xws ntawm cov khoom siv raw los ntawm kev sib xyaw ua ke kom ntseeg tau tias muaj cov tshuaj lom neeg ruaj khov thiab cov yam ntxwv yaj.
Kev yaj kub siab: Kub siab yaj thiab do hauv lub cub tawg kom ua tiav qib siab ntawm homogenization.
Xaus lus
BasaltRaws li ib qho khoom siv ntuj tsim uas muaj txiaj ntsig zoo, nws yog ib qho khoom siv tseem ceeb rau kev tsim cov khoom siv ua tau zoo cov fiber basaltLos ntawm kev xaiv cov khoom siv raw thiab cov txheej txheem kho mob nruj, nws tuaj yeem ua kom muaj cov fibers basalt zoo, uas siv dav hauv ntau qhov chaw, xws li aerospace, kev tsim kho, thiab tsheb. Nrog rau kev txhim kho thev naus laus zis tas mus li, basalt thiab nws cov ntaub ntawv fiber yuav ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw thiab txhawb kev nce qib thiab kev txhim kho ntawm lub zej zog. Yog li ntawd, kev txhim kho thiab kev siv cov khoom muaj nqis ntuj no yuav coj tus nqi ntau dua rau tib neeg.
