Fiberglass ndi pamwamba pa nsalu yake pogwiritsa ntchito PTFE, rabara ya silicone, vermiculite ndi njira zina zosinthira zinthu zitha kusintha ndikuwonjezera magwiridwe antchito a fiberglass ndi nsalu yake.

1. PTFE yokutidwa pamwamba pafiberglassndi nsalu zake

PTFE ili ndi kukhazikika kwa mankhwala, kusamatirira bwino, kukana kukalamba bwino, kukana dzimbiri, kudziyeretsa ndi zina zabwino kwambiri, koma pali zinthu zoyipa zamakina, kukana kuvala bwino, kutentha koipa komanso zolakwika zina, fiberglass ili ndi zinthu zabwino kwambiri zamakina komanso zakuthupi ndi zamakemikolo, fiberglass ndi pamwamba pake pa nsalu yokutidwa ndiPTFE, osati kungowonjezera zolakwika za PTFE ndikukonza, komanso kusewera zabwino za magwiridwe antchito a fiberglass, komanso nthawi yomweyo kuchepetsa fiberglass ndi nsalu zake. Magwiridwe antchito, pomwe amachepetsa kufooka kwa fiberglass, mapangidwe a mphamvu yayitali, kukana kukwawa bwino, fiberglass yosakalamba / zipangizo za PTFE. PTFE yokutidwa ndi fiberglass nthawi zambiri imagwiritsa ntchito njira zingapo zoyikiramo, pambuyo pochotsa nsalu ya fiberglass kutentha kudzera mu thanki yoyikiramo yokutidwa ndi PTFE, kenako kuumitsa, kuphika, kuwotcha ndi njira zina, madzi ochulukirapo ndi kusungunuka kwa emulsion, kusiya tinthu ta PTFE tomwe timamatira kwambiri ku nsalu ya fiberglass, zinthuzo zili ndi mawonekedwe a PTFE, komanso magwiridwe antchito abwino a fiberglass, omwe amagwiritsidwa ntchito kwambiri ngati nyumba. Zinthuzo zili ndi mawonekedwe a PTFE komanso magwiridwe antchito abwino a fiberglass, ndipo zimagwiritsidwa ntchito kwambiri ngati zida zomangira, zida zotenthetsera, zida zokangana, ndi zina zotero. Zimagwiritsidwa ntchito kwambiri pomanga, zamagetsi ndi zina.

2. Fiberglass ndi pamwamba pake yokutidwa ndi rabala ya silicone

Rabala ya silicone ili ndi kutchinjiriza kwabwino kwamagetsi, kukana kutentha kwambiri komanso kotsika, kukana kukalamba kwa mpweya, ndi zina zotero, mu fiberglass ndi pamwamba pake yokutidwa ndi rabala ya silicone, imatha kusintha magwiridwe antchito opindika afiberglassndi kukana kuvala. Fiberglass ndi nsalu zake ngati substrate, yokutidwa ndi rabara ya silicone kuti apange nsalu zophimbidwa ndi fiberglass, zokhala ndi mphamvu yolimba kwambiri, kukhazikika kwa mawonekedwe, kutchinjiriza bwino magetsi komanso kukana dzimbiri kwa mankhwala ndi makhalidwe ena abwino, nthawi zambiri ngati zinthu zotetezera magetsi, zimatha kupangidwa kukhala nsalu zotetezera kutentha, chivundikiro, ndi zina zotero; monga zinthu zotetezera kutentha zingagwiritsidwe ntchito ngati payipi, matanki mkati ndi kunja kwa wosanjikiza woteteza kutentha; komanso ngati filimu yomanga, zipangizo zopakira, monga zomangamanga, mphamvu ndi mafakitale ena. Ingagwiritsidwenso ntchito ngatifilimu yomangandi zinthu zopakira m'makampani omanga, mphamvu ndi mafakitale ena.

3. Kupaka vermiculite pamwamba pa fiberglass ndi nsalu zake

Vermiculite ndi mchere wa hydroaluminosilicate wokhala ndi magnesium womwe umatha kupirira kutentha kwambiri mpaka 1250°C. Pambuyo potenthedwa ndi kukulitsidwa, kuchuluka kwake kumawonjezeka ndipo kutentha kwake kumakhala kochepa, ndipo vermiculite yokulirapo imakhala ndi mphamvu zochepa, mphamvu zabwino zotetezera mankhwala, kutentha ndi phokoso, komanso kukana moto ndi chisanu. Ngakhale fiberglass ili ndi kukana kutentha bwino, koma kugwiritsa ntchito kutentha kwa nthawi yayitali sikuyenera kukhala kokwera kwambiri, pamene lawi lotseguka la moto limatha kulowa ngakhale muzinthu zake, vermiculite yokutidwa ndi fiberglass ndi pamwamba pa nsalu zawo, vermiculite imatha kukulitsa kukana moto kwa fiberglass, komanso imagwiranso ntchito pa zotsatira za kutetezedwa kutentha koletsa moto. Zogulitsa za fiberglass zophimbidwa ndi Vermiculite zimakhala ndi kukana kutentha kwambiri komanso kutetezedwa bwino kutentha komanso kukana moto, ndipo zimagwiritsidwa ntchito poteteza kuwotcherera, kuteteza moto,kukulunga mapaipindi zina zotero.
