Kodi zigawo zikuluzikulu za ndodo zamagalasi ndi ndodo zamagalasi zopangira ng’anjo zotenthetsera ndi ziti?

Galasi fiber ndodo ndi galasi fiber ndodo (omwe kale ankatchedwa ulusi wa magalasi) opangira ng’anjo yotenthetsera ndi zinthu zopanda zitsulo zomwe zimagwira ntchito bwino kwambiri. Lili ndi mitundu yambiri. Ubwino wake ndi kutchinjiriza kwabwino, kukana kutentha, kukana kwa dzimbiri komanso mphamvu yayikulu yamakina. Komabe, kuipa kwake ndi brittleness komanso kusamva bwino kukana. Zimapangidwa ndi pyrophyllite, mchenga wa quartz, miyala yamchere, dolomite, boron calcite ndi brucite monga zipangizo zomwe zimasungunuka, kukoka, kuvulaza ndi kuluka kutentha kwambiri. M’mimba mwake monofilament ndi ma microns angapo mpaka ma microns makumi awiri, omwe ndi ofanana ndi 1/20-1/5 ya tsitsi. Mtolo uliwonse wa fiber precursors imakhala ndi mazana kapena mazana. Zikwi za monofilaments. Ndodo za fiberglass ndi ndodo za fiberglass zopangira ng’anjo zoyatsira moto nthawi zambiri zimagwiritsidwa ntchito ngati zida zolimbikitsira m’magawo azachuma monga zida zophatikizika, zotchingira magetsi ndi zida zoyatsira, ndi magawo ozungulira.

Zigawo zazikulu za ndodo zopangira magalasi ndi ndodo zamagalasi zopangira ng’anjo zotenthetsera ndi silika, alumina, calcium oxide, boron oxide, magnesium oxide ndi sodium oxide. Malinga ndi zamchere zili mu galasi, zikhoza kugawidwa mu mchere wopanda galasi CHIKWANGWANI (0% -2% sodium okusayidi, wa aluminoborosilicate galasi), sing’anga alkali galasi CHIKWANGWANI (8% -12% sodium okusayidi, wa boron- okhala ndi galasi kapena borosilicate-free glass) galasi la sodium) ndi galasi lapamwamba la alkali. Ulusi wagalasi (sodium oxide, wopitilira 13%, galasi la sodium silicate).
