Fiberglass ndi nsalu yake pamwamba pa zokutira PTFE, mphira silikoni, vermiculite ndi mankhwala ena kusinthidwa akhoza kusintha ndi kupititsa patsogolo ntchito ya fiberglass ndi nsalu yake.

1. PTFE TACHIMATA padzikogalasi la fiberglassndi nsalu zake

PTFE ali mkulu mankhwala bata, wapadera sanali adhesion, kwambiri ukalamba kukana, dzimbiri kukana, kudziyeretsa kudziyeretsa ndi makhalidwe ena abwino, koma pali osauka makina katundu, osauka avale kukana, osauka matenthedwe madutsidwe ndi zolakwika zina, fiberglass ali kwambiri makina katundu ndi thupi ndi mankhwala katundu, fiberglass ndi nsalu pamwamba yokutidwa ndiPTFE, osati kuti apange zolakwika za PTFE ndi kusintha, komanso kusewera ubwino wa fiberglass ntchito, ndipo nthawi yomweyo kuchepetsa fiberglass ndi nsalu zake. Magwiridwe, pamene kuchepetsa brittleness wa fiberglass, mapangidwe mkulu mphamvu, zabwino abrasion kukana, ukalamba zosagwira fiberglass / PTFE zipangizo. Fiberglass TACHIMATA PTFE zambiri ntchito angapo impregnation ndondomeko, pambuyo kutentha mankhwala a fiberglass nsalu kudzera mu impregnation thanki TACHIMATA ndi PTFE kubalalitsidwa, ndiyeno kuyanika, kuphika, sintering ndi mankhwala ena, ndi owonjezera madzi ndi zosungunulira evaporation wa emulsion, kusiya PTFE utomoni particles mwamphamvu amatsatira. ku nsalu ya fiberglass, zinthuzo zili ndi mawonekedwe onse a PTFE, komanso magwiridwe antchito abwino kwambiri a fiberglass, omwe amagwiritsidwa ntchito ngati kumanga Zinthuzo zili ndi makhalidwe onse a PTFE ndi ntchito yabwino kwambiri ya fiberglass, ndipo amagwiritsidwa ntchito ngati zipangizo zomangira, zipangizo zotetezera, zipangizo zowonongeka, ndi zina. Zimagwiritsidwa ntchito pomanga, zamagetsi ndi zina.

2. Fiberglass ndi nsalu yake pamwamba yokutidwa ndi mphira silikoni

Labala ya silicone imakhala ndi kutchinjiriza kwamagetsi, kukana kutentha kwambiri komanso kutsika, kukana kwa oxygen kukalamba, etc., mu fiberglass ndi nsalu yake pamwamba yokutidwa ndi mphira wa silikoni, imatha kupititsa patsogolo magwiridwe antchito agalasi la fiberglassndi kuvala kukana. Fiberglass ndi nsalu zake ngati gawo lapansi, zokutidwa ndi mphira wa silikoni kuti apange nsalu zokutira za fiberglass, zokhala ndi mphamvu zolimba kwambiri, kukhazikika kwamkati, kutchinjiriza kwamagetsi komanso kukana kwa dzimbiri ndi zinthu zina zabwino kwambiri, nthawi zambiri ngati zida zotchingira magetsi, zitha kupangidwa kukhala nsalu yotchinga, casing, etc.; monga anticorrosive material angagwiritsidwe ntchito ngati payipi, akasinja mkati ndi kunja kwa wosanjikiza anticorrosive; komanso ngati filimu yomanga, zonyamula katundu, monga pomanga, mphamvu ndi mafakitale ena. Itha kugwiritsidwanso ntchito ngatifilimu yomangandi zonyamula katundu mu zomangamanga, mphamvu ndi mafakitale ena.

3. Kuphimba vermiculite pamwamba pa fiberglass ndi nsalu zake

Vermiculite ndi mchere wokhala ndi magnesium wokhala ndi hydroaluminosilicate womwe umatha kupirira kutentha kwambiri mpaka 1250 ° C. Pambuyo pa kutenthedwa ndi kukulitsidwa, kuchuluka kwake kumawonjezeka ndipo kutentha kwake kumakhala kochepa, ndipo vermiculite yowonjezera imakhala yochepa kwambiri, imakhala yabwino yotetezera mankhwala, kutentha ndi kutsekemera kwa mawu, ndi kukana moto ndi chisanu. Ngakhale fiberglass ali wabwino kutentha kukana, koma ntchito yaitali kutentha sayenera kukhala mkulu, pamene lotseguka moto lawi akhoza ngakhale kudutsa mankhwala ake, vermiculite TACHIMATA mu fiberglass ndi nsalu pamwamba awo, vermiculite akhoza kusintha moto kukana wa. magalasi a fiberglass, komanso amathandizira pakuchepetsa kutentha koletsa moto. Zopangidwa ndi magalasi a fiberglass okhala ndi vermiculite zimakhala ndi kukana kutentha kwambiri komanso kutsekemera kwabwino kwa kutentha komanso zinthu zoletsa moto, ndipo zimagwiritsidwa ntchito poteteza kuwotcherera, kuteteza moto,kukulunga chitolirondi zina zotero.
