Ziziphi iimpawu zokusetyenziswa kombhobho we-epoxy?
Iyokuqala ukubambelela ngamandla. Umbhobho we-epoxy unokubambelela kakuhle kwizinto ezahlukeneyo. Oku kungenxa yokuba i-epoxy resin esetyenziswe kumbhobho we-epoxy inokunciphisa okuphantsi kunye noxinzelelo lwangaphakathi ngexesha lenkqubo yokunyanga, ekwancedisa amandla ayo okunamathela ngokubanzi.
Okwesibini kukwahluka. Iintlobo ngeentlobo zentlaka ze-epoxy, ii-agent zokunyanga kunye neenkqubo zokuguqula zinokuhlangabezana neemfuno zeendlela ezahlukeneyo zokusebenzisa, kwaye uluhlu lokucwangcisa lunokuqala ukusuka kwi-viscosity ephantsi kakhulu ukuya kwizinto eziqinileyo ezinyibilikayo.
Okwesithathu, iimpawu ezintle zoomatshini. I-epoxy resin ephilileyo ineempawu ezintle kakhulu zoomatshini.
Ukucuthwa komjikelo wesine nako kuphantsi kakhulu. Ukusabela phakathi kwe-epoxy resin kunye ne-ejenti yokunyanga iqhutyelwa ngokuphendula ngokuthe ngqo kokongeza okanye ukuvuleka kwe-polymerization yamaqela e-epoxy kwi-molecule ye-resin. Akukho manzi okanye ezinye iimveliso eziguqukayo ezikhutshwayo. Xa kuthelekiswa ne-polyester resin engaxutywanga kunye ne-phenolic resin, inezinga eliphantsi lokunciphisa ngexesha lokunyanga.
Eyesihlanu kukulula. Ngokukhetha ii-agent ezahlukeneyo zokunyanga, inkqubo ye-epoxy resin yombhobho we-epoxy inokunyangwa kwi-0 ~ 180 ° C.
