Zipangizo zolimbikitsira muzinthu zogundana makamaka zimapatsa zinthu zogundana mphamvu zamakina, zomwe zimawalola kupirira mphamvu yolemetsa yomwe imayendetsedwa ndi makina opangira makina popanga zinthu zogundana komanso mphamvu yamphamvu, kumeta ubweya, komanso kupsinjika komwe kumapangidwa ndi braking panthawi yogwiritsa ntchito. , kupewa kusweka ndi kuwonongeka.
Zomwe zimafunikira pazida zolimbana ndi zida zolimbitsa zikuphatikizapo: kulimbikitsa kwambiri; kukana kutentha kwabwino; koyefit koyenera kokhazikika komanso kokhazikika; kuuma kwapakati; ndi bwino ntchito operability. Mchere womwe umagwiritsidwa ntchito ngati zida zolimbikitsira nthawi zambiri amakhala ulusi wamafuta, makamaka ulusi wamchere, ulusi wa asbestos, ulusi wa basalt, ndi zina zambiri.
Hebang Fiber ndi wopanga yemwe amagwira ntchito kwambiri popanga ulusi wamchere wopanda asibesitosi ndi ulusi wa basalt. Ulusiwo umasungunuka ndi kupota pa kutentha kwakukulu kwa 1450 ° C ndipo zimakhala ndi kutentha kwabwino. Kutalika kwa m'mimba mwake ndi kwakukulu kuposa nthawi 30 ndipo kumalimbitsa bwino kwambiri.
