Ziziphi iimpawu zesicelo se-epoxy glass fiber pipe?

1. Iifom ezahlukeneyo. Ii-resins ezahlukeneyo, iiarhente zokunyanga, kunye neenkqubo zokuguqula zinokuphantse zilungelelane neemfuno zezicelo ezahlukeneyo kwifom, kwaye uluhlu lunokuvela kwi-viscosity esezantsi kakhulu ukuya kwindawo ephezulu yokunyibilika.

2. Ukunyanga okufanelekileyo. Khetha iindidi zeearhente ezahlukeneyo zokuphilisa, inkqubo ye-epoxy resin inokuphiliswa kwinqanaba lobushushu le-0 ~ 180 ℃.

3. Ukubambelela okuqinileyo. Ubukho bepolar hydroxyl kunye ne-ether bond [1] ngokwendalo kwitsheyini yemolekyuli ye-epoxy resin iyenza ibenoncanyelo oluphezulu kwizinto ezahlukeneyo. I-shrinkage ye-epoxy resin iphantsi xa iphilisa, kwaye uxinzelelo lwangaphakathi olwenziwe luncinci, olukwanceda ekuphuculeni amandla okubambelela.

4. Ukuncipha okuphantsi. Ukusabela phakathi kwe-epoxy resin kunye ne-agent ephilisayo esetyenzisiweyo iqhutywa ngokuphendula ngokuthe ngqo kokudibanisa okanye ukuvuleka kwe-ring-open polymerization reaction yamaqela epoxy kwi-molecule ye-resin, kwaye akukho manzi okanye ezinye iimveliso eziguqukayo ezikhutshwayo. Xa kuthelekiswa neentyantyambo ze-polyester ezingaxutywanga kunye ne-phenolic resins, zibonisa i-shrinkage ephantsi kakhulu (ngaphantsi kwe-2%) ngexesha lokunyanga.

5. Iipropati zoomatshini. Inkqubo ye-epoxy resin ephilisiweyo ineempawu ezintle kakhulu zoomatshini.
