Kuthini nge iimveliso zebhodi epoxy resin

I-resin, ukuqina, iinkqubo zokulungisa ziyafumaneka ukuze zilungele zonke iimfuno zefomu yesicelo, ukusuka kwii-viscosities eziphantsi kakhulu ukuya kwindawo ephezulu yokunyibilika. Iintlobo ezahlukeneyo zokunyanga zisetyenziselwa ukunyanga, kwaye inkqubo ye-epoxy resin inokunyangwa phantse kuluhlu lobushushu obuphakathi kwe-0 ukuya kwi-180 °C.

1. Ukubambelela okuqinileyo

Ubukho bepolar hydroxyl kunye neebhondi ze-ether ezikwitsheyini yemolekyuli ye-epoxy resin iyenza ibe nokuncamathela okuphezulu kwizinto ezahlukeneyo. I-epoxy resins ine-shrinkage ephantsi ngexesha lokunyanga kunye noxinzelelo oluphantsi lwangaphakathi, olukwanegalelo ekuphuculeni amandla okubambelela.

2. Ukunciphisa olomeleleyo

Ukusabela phakathi kwe-epoxy resin kunye ne-agent ephilisayo esetyenzisiweyo iqhutyelwa ngokuphendula ngokuthe ngqo kokudibanisa okanye ukuphendulwa kwe-polymerization yokuvula i-ring-ring yeqela le-epoxy kwi-molecule ye-resin, kwaye akukho manzi okanye ezinye iimveliso eziguqukayo ezikhutshwayo. Babonisa i-shrinkage ephantsi kakhulu (ngaphantsi kwe-2%) ngexesha lokunyanga xa kuthelekiswa ne-unsaturated polyester resins kunye ne-phenolic resins.

3. Umsebenzi womatshini

Inkqubo ye-epoxy resin ephilileyo ineempawu ezibalaseleyo zoomatshini.

4. Umsebenzi wombane

Inkqubo ye-epoxy resin enyangisiweyo yinto egqwesileyo yokugquma eneempawu eziphezulu ze-dielectric, ukumelana nokuvuza komphezulu kunye nokumelana ne-arc.

5. Ukuzinza kweMichiza

Ngokubanzi, inkqubo ye-epoxy resin enyangisiweyo inokumelana okugqwesileyo kwe-alkali, ukuxhathisa kweasidi kunye nokumelana ne-solvent. Njengeminye imisebenzi yeenkqubo ze-epoxy eziphilisiweyo, ukuzinza kweekhemikhali kuxhomekeke kwi-resin ekhethiweyo kunye ne-arhente yokunyanga. Ukukhethwa ngokufanelekileyo kwe-epoxy resin kunye ne-ejenti yokunyanga ingenza ukuba ibe nomsebenzi okhethekileyo wokuzinza kweekhemikhali.

6. Uzinzo lwesikali

Indibaniselwano yezi mpawu zingentla inika iinkqubo ze-epoxy resin ezibalaseleyo uzinzo kunye nokuqina.

7. Ukumelana nokungunda

Iinkqubo ze-epoxy ezinyangisiweyo ziyaxhathisa kuninzi lokungunda kwaye zinokusetyenziswa kwiimeko ezinzima zetropiki.
