Kodi mukudziwa zingapo za epoxy galasi CHIKWANGWANI chitoliro?

The epoxy glass fiber chubu imapangidwa ndi nsalu yamagetsi yamagetsi yopanda alkali yopanda galasi yomwe imayikidwa ndi epoxy resin, yophikidwa, ndi kukonzedwa ndi kukanikiza kotentha mu nkhungu. Gawo la mtanda ndi ndodo yozungulira. Ndodo ya nsalu yamagalasi imakhala ndi zida zapamwamba zamakina. Pamwamba pa epoxy galasi fiber chubu ayenera kukhala yosalala popanda thovu lililonse, madontho mafuta ndi zosafunika. Mtundu wosagwirizana, kusisita pang’ono, ndi zina zotero zonse zili mkati mwazololedwa. Mapaipi a epoxy fiberglass amagwiritsidwa ntchito popanga zida zamagetsi, zinthu zonyowa komanso mafuta osinthira.

Makhalidwe a mapaipi a epoxy glass fiber ndi otakata, ndipo kuchuluka kwa ntchito ndikokulirapo, ndipo mawonekedwe ake ndi osiyanasiyana. Utomoni, wothandizira machiritso, ndi makina osinthira amatha kutengera zofunikira zamitundu yosiyanasiyana pamawonekedwe, ndipo mitunduyo imatha kukhala kuchokera ku viscosity yotsika kwambiri mpaka zolimba zosungunuka kwambiri. Kachiwiri, kuchiritsa ndikothandiza kwambiri. Sankhani mitundu yosiyanasiyana yochiritsa, ndipo epoxy resin system imatha kuchiritsidwa pa kutentha kwa 0-180 ° C.

Chinthu chimodzi chimene ndiyenera kunena ndi chakuti ili ndi zomatira zolimba. Pali magulu a polar hydroxyl ndi ma ether chain mu unyolo wa epoxy resin, womwe umapangitsa kuti ikhale yomatira kwambiri kuzinthu zosiyanasiyana. Kuchepa kwa utomoni wa epoxy kumakhala kochepa pochiritsa, ndipo kupsinjika kwamkati komwe kumapangidwa kumakhala kochepa, komwe kumathandizanso kukulitsa mphamvu zomata. Imakhalanso ndi kuchepa kochepa. Zomwe zimachitika pakati pa epoxy resin ndi mankhwala ochiritsira zimachitika ndikuwonjezera mwachindunji kapena kutsegula kwa ma polymerization kwamagulu a epoxy mu molekyulu ya utomoni, ndipo palibe madzi kapena zinthu zina zosakhazikika zomwe zimatulutsidwa. Malinga ndi deta yoyenera, poyerekeza ndi unsaturated poliyesitala utomoni ndi phenolic utomoni, shrinkage pa ndondomeko kuchiritsa ndi otsika kwambiri, pafupifupi 2%. .
