Introduction to the application functional characteristics of epoxy glass fiber board

Epoxy glass fiber board, epoxy phenolic laminated glass cloth board, epoxy resin generally refers to organic polymer compounds containing two or more epoxy groups in the molecule, except for some, their relative molecular masses are not high. The molecular structure of epoxy resin is characterized by the active epoxy group in the molecular chain. The epoxy group can be located at the end, in the middle or in a cyclic structure of the molecular chain. Because the molecular structure contains active epoxy groups, they can undergo cross-linking reactions with various types of curing agents to form insoluble and infusible polymers with a three-way network structure.

Epoxy glass fiber board application characteristics and functions:

1. Iipropati zoomatshini. Inkqubo ye-epoxy resin ephilisiweyo ineempawu ezintle kakhulu zoomatshini.

2. Ukunamathela okunamandla. Amaqela e-polar hydroxyl kunye ne-ether bond kwi-molecular chain ye-epoxy resins yenza ukuba inamathele kakhulu kwizinto ezahlukeneyo. Ukuncipha kwe-epoxy resin kusezantsi xa unyanga, kwaye uxinzelelo lwangaphakathi oluvelisiweyo lincinci, olunceda ukuphucula amandla okubambelela.

3. Ukunyanga okufanelekileyo. Khetha iindidi zeearhente ezahlukeneyo zokuphilisa, inkqubo ye-epoxy resin inokuphiliswa kwinqanaba lobushushu le-0 ~ 180 ℃.

4. Iifom ezahlukeneyo. Ii-resins ezahlukeneyo, iiarhente zokunyanga, kunye neenkqubo zokuguqula zinokuphantse zilungelelane neemfuno zezicelo ezahlukeneyo kwifom, kwaye uluhlu lunokuvela kwi-viscosity esezantsi kakhulu ukuya kwindawo ephezulu yokunyibilika.

5. Ukuncipha okuphantsi. Impendulo phakathi kwe-epoxy resin kunye ne-arhente yokuphilisa esetyenziswayo yenziwa ngokudibanisa ngokuthe ngqo okanye ukuvulwa kwendandatho yokuphendula kwamaqela epoxy kwimolekyuli ye-resin, kwaye akukho manzi okanye ezinye iimveliso ezivelayo. Xa kuthelekiswa nentlaka ye-polyester engafakwanga kunye ne-phenolic resins, zibonisa ukuncipha okuphantsi kakhulu (ngaphantsi kwe-2%) ngexesha lokunyanga.
