Kuthiwani imikhiqizo yebhodi le-epoxy resin

I-resin, harderer, modifier systems ziyatholakala ukuze zivumelane cishe nazo zonke izidingo zefomu lesicelo, kusukela kuma-viscosity aphansi kakhulu kuya kokuqinile kwendawo yokuncibilika. Ama-ejenti ahlukahlukene okwelapha asetshenziselwa ukwelapha, futhi uhlelo lwe-epoxy resin lungelapheka cishe ebangeni lokushisa lika-0 kuya ku-180 °C.

1. Ukunamathela okuqinile

Ukuba khona kwe-polar hydroxyl kanye nebhondi ye-ether etholakala ochungechungeni lwemolekyuli ye-epoxy resin kuyenza ibe nokunamathela okuphezulu ezintweni ezahlukahlukene. Ama-epoxy resins ane-shrinkage ephansi ngesikhathi sokwelapha kanye nengcindezi ephansi yangaphakathi, okubuye kube nomthelela ekuthuthukisweni kwamandla okunamathela.

2. Ukufinyeza okuqinile

Ukusabela phakathi kwe-epoxy resin kanye ne-ejenti yokwelapha esetshenziswayo kwenziwa ngokusabela kokwengezwa okuqondile noma ukusabela kwe-polymerization yokuvula indandatho yeqembu le-epoxy ku-molecule ye-resin, futhi awekho amanzi noma eminye imikhiqizo eguqukayo ekhishwayo. Zibonisa ukuncipha okuphansi kakhulu (ngaphansi kuka-2%) ngesikhathi sokuphulukiswa uma kuqhathaniswa nezinhlayiya ze-polyester ezingasetshenzisiwe kanye nama-phenolic resins.

3. Umsebenzi wemishini

Uhlelo lwe-epoxy resin olulahliwe lunezici ezinhle kakhulu zemishini.

4. Umsebenzi kagesi

Uhlelo oluphulukisiwe lwe-epoxy resin luyinto enhle kakhulu yokuvikela enezici eziphezulu ze-dielectric, ukumelana nokuvuza kwendawo kanye nokumelana kwe-arc.

5. Ukuzinza kwamakhemikhali

Ngokuvamile, isistimu ye-epoxy resin ephulukisiwe inokumelana okuhle kakhulu kwe-alkali, ukumelana ne-asidi nokumelana ne-solvent. Njengeminye imisebenzi yezinhlelo ze-epoxy eselashiwe, ukuzinza kwamakhemikhali kuncike ku-resin ekhethiwe kanye ne-ejenti elaphayo. Ukukhethwa okufanele kwe-epoxy resin kanye ne-ejenti yokwelapha kungayenza ibe nomsebenzi okhethekile wokuzinza kwamakhemikhali.

6. Ukuzinza kwesikali

Inhlanganisela yezici eziningi ezingenhla inika amasistimu e-epoxy resin ukuzinza okuhle kakhulu nokuqina.

7. Ukumelana nesikhunta

Amasistimu e-epoxy aphulukisiwe amelana nesikhunta esiningi futhi angasetshenziswa ezimeni ezishisayo ezishisayo.
