Makhalidwe a ntchito ya epoxy glass fiber chubu

Epoxy fiberglass chitoliro ndi chinthu chofala pazida zamagetsi m’nthawi yathu ino. Chifukwa cha mawonekedwe akeake, imatha kugwiritsidwa ntchito ngati gawo la zida zoteteza. Ndipo ngakhale m’malo achinyezi, itha kugwiritsidwanso ntchito ndi mafuta a transformer. Kenako, tikuwonetsani momwe mungagwiritsire ntchito epoxy glass fiber chubu mwatsatanetsatane.

Kugwiritsa ntchito mawonekedwe a epoxy glass fiber chubu

1. Mitundu yosiyanasiyana. Ma resins osiyanasiyana, machiritso, ndi makina osinthira amatha kugwiritsidwa ntchito pazofunikira zamitundu yosiyanasiyana yogwiritsira ntchito, ndipo masikelo ake amatha kukhala otsika kwambiri mpaka zolimba zosungunuka kwambiri.

2. Kuchiritsa bwino. Sankhani mitundu yosiyanasiyana yochiritsa, makina a epoxy resin amatha kuchiritsidwa pa kutentha kwa 0 ~ 180 ℃.

3. Kumamatira mwamphamvu. Kukhalapo kwa polar hydroxyl ndi ether bond [1] komwe kumakhala mu utomoni 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 utomoni wa epoxy ndi mankhwala ochiritsira omwe amagwiritsidwa ntchito amachitidwa ndi kuwonjezereka kwachindunji kapena kutsegula kwa ma polymerization kwamagulu a epoxy mu molekyulu ya utomoni, ndipo palibe madzi kapena zinthu zina zosakhazikika zomwe zimatulutsidwa. Poyerekeza ndi unsaturated polyester resins ndi phenolic resins, amawonetsa kufupikitsa kochepa kwambiri (osakwana 2%) pochiritsa.

5. Mawotchi katundu. Makina ochiritsidwa a epoxy resin ali ndi mawonekedwe abwino kwambiri.
