Yiziphi izici ze ibhodi le-epoxy resin?

Ibhodi le-epoxy resin libizwa nangokuthi ibhodi lokufakelwa, i-epoxy glass fiber board, ibhodi ye-3240 epoxy glass fiber. I-epoxy resin ibhekisela kumakhemikhali e-polymer ephilayo aqukethe amaqembu amabili noma ngaphezulu e-epoxy ku-molecule. Isisindo samangqamuzana esihlobene asiphezulu. Isakhiwo samangqamuzana e-epoxy resin sibonakala ngeqembu le-epoxy elisebenzayo kuchungechunge lwamangqamuzana. Iqembu le-epoxy lingatholakala ekugcineni, phakathi nendawo noma esakhiweni se-cyclic seketango lamangqamuzana. Ngenxa yokuthi ukwakheka kwamangqamuzana kuqukethe amaqembu e-epoxy asebenzayo, angabhekana nokusabela okuxhumanisa ngezinhlobo ezahlukene zama-ejenti okwelapha ukuze akhe ama-polymer angancibilikiyo futhi angenakunyakaziswa anesakhiwo senethiwekhi yezindlela ezintathu.

Ama-resin anhlobonhlobo, ama-ejenti elaphayo, kanye nezinhlelo zokulungisa zingacishe zivumelane nezidingo zezicelo ezahlukahlukene efomini, futhi ububanzi bungaba ukusuka ku-viscosity ephansi kakhulu ukuya kokuqinile kwendawo encibilika. Ama-ejenti okwelapha ahlukahlukene asetshenziselwa uhlangothi lokuphulukisa, futhi uhlelo lwe-epoxy resin lucishe lwelapheke ezingeni lokushisa elingu-0~180℃.

1, ukunamathela okuqinile

Ukuba khona kwe-polar hydroxyl kanye nebhondi ye-ether etholakala ochungechungeni lwemolekyuli ye-epoxy resin kuyenza ibe nokunamathela okuphezulu ezintweni ezahlukahlukene. Ukuncipha kwe-epoxy resin kuphansi lapho uphulukisa, futhi ukucindezeleka kwangaphakathi okukhiqizwa kuncane, okusiza futhi ukuthuthukisa amandla okunamathela.

2, ukufinyela okuqinile

“Ukusabela kwe-epoxy resin kanye ne-ejenti yokwelapha esetshenziswayo kwenziwa ngokusabela kokwengezwa okuqondile noma ukusabela kwe-polymerization yokuvula indandatho yamaqembu e-epoxy ku-molecule ye-resin, futhi awekho amanzi noma eminye imikhiqizo eguquguqukayo ekhishwayo. Uma kuqhathaniswa nezinhlayiya ze-polyester ezingasetshenzisiwe kanye nama-phenolic resins, abonisa ukuncipha okuphansi kakhulu (ngaphansi kuka-2%) ngesikhathi sokwelashwa.

3, izakhiwo mechanical

Uhlelo lwe-epoxy resin olulahliwe lunezici ezinhle kakhulu zemishini.

4, ukusebenza kukagesi

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

5, ukuzinza kwamakhemikhali

Ngokuvamile, isistimu ye-epoxy resin ephulukisiwe inokumelana okuhle kakhulu kwe-alkali, ukumelana ne-asidi nokumelana ne-solvent. Njengezinye izakhiwo zesistimu ye-epoxy eselashiwe, ukuzinza kwamakhemikhali nakho kuncike ku-resin ekhethiwe kanye ne-ejenti yokwelapha. Ukukhethwa okufanele kwe-epoxy resin kanye ne-ejenti yokwelapha kungayenza ibe nokuzinza okukhethekile kwamakhemikhali.

6, ukuzinza kwe-dimensional

Inhlanganisela yezinto eziningi ezingenhla yenza isistimu ye-epoxy resin ibe nokuzinza okuvelele nokuqina.

7, ukumelana nesikhunta

Isistimu ye-epoxy resin ephulukisiwe imelana nesikhunta esiningi futhi ingasetshenziswa ngaphansi kwezimo ezishisayo ezishisayo.
