Iimpawu zokusetyenziswa kweemveliso zebhodi ye-epoxy resin
Iimpawu zokusetyenziswa kwe ibhodi epoxy resin iimveliso
1. Iifom ezahlukeneyo, iintlaka ezahlukeneyo, ii-agent zokunyanga, kunye neenkqubo zokulungisa zingaphantse zilungele iimfuno zezicelo ezahlukeneyo, ukusuka kwi-viscosity ephantsi kakhulu ukuya kwizinto eziqinileyo eziphezulu zokunyibilika.
2. Ukunyanga okufanelekileyo: Khetha iindidi ezahlukeneyo zokunyanga, kunye nenkqubo ye-epoxy resin inokunyangwa kwiqondo lokushisa elingu-0~180℃.
3. Ukubambelela okuqinileyo: Ubukho bepolar hydroxyl kunye ne-ether bond ehambelana ne-molecular chain ye-epoxy resin yenza ukuba ibe nokubambelela okuphezulu kwizinto ezahlukeneyo. I-shrinkage ye-epoxy resin iphantsi xa iphilisa, kwaye uxinzelelo lwangaphakathi olwenziwe luncinci, olunceda ekuphuculeni amandla okubambelela.
4. Ukuncipha okuphantsi. Ukusabela phakathi kwe-epoxy resin kunye ne-ejenti yokuphilisa iqhutywa ngokuphendula ngokuthe ngqo kokudibanisa okanye ukuvuleka kwe-ring-open polymerization reaction yeqela le-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. Iimpawu zeMechanical: Inkqubo ye-epoxy resin ephilisiwe ineempawu ezibalaseleyo zoomatshini.
