Kugwiritsa ntchito mica chubu
Ntchito makhalidwe a mica chubu
1. Mitundu yosiyanasiyana: Ma resin osiyanasiyana, machiritso, ndi makina osinthira amatha kugwiritsidwa ntchito pazofunikira zamitundu yosiyanasiyana, ndipo masikelo ake amatha kukhala otsika kwambiri mpaka olimba kwambiri.
2. Kuchiritsa bwino: Sankhani mitundu yosiyanasiyana yochiritsa, dongosolo la epoxy resin litha kuchiritsidwa mkati mwa kutentha kwa 0 ~ 180 ℃.
3. Kumamatira mwamphamvu: Kukhalapo kwa polar hydroxyl ndi ether bond mu unyolo wa molekyulu wa epoxy resin kumapangitsa kuti ikhale yomatira kwambiri kuzinthu zosiyanasiyana. Kufupikitsa kwa epoxy resin kumakhala kochepa pochiritsa, ndipo kupsinjika kwamkati komwe kumapangidwa kumakhala kochepa, komwe kumathandizanso kupititsa patsogolo mphamvu yomatira.
4. Kufupikitsa kochepa: Zomwe zimachitika pakati pa epoxy resin ndi mankhwala ochiritsira zimachitika kudzera muzochita zowonjezera kapena kutsegula polima zamagulu a epoxy mu molekyulu ya resin, ndipo palibe madzi kapena zinthu zina zosakhazikika zomwe zimatulutsidwa. Poyerekeza ndi unsaturated polyester resins ndi phenolic resins, amawonetsa kufupikitsa kochepa kwambiri (osakwana 2%) panthawi yochiritsa.
5. Makina amakina: Dongosolo lochiritsidwa la epoxy resin lili ndi makina abwino kwambiri.
