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. Toetra mekanika. Ny rafitra resin epoxy resahina dia manana toetra mekanika tena tsara.

2. Adhesion mahery. Ny vondrona hydroxyl polar sy ny fatoran’ny ether ao amin’ny rojom-bolo misy ny epoxy resins dia mahatonga azy io hifikitra amin’ny akora isan-karazany. Ny fihenan’ny resin epoxy dia ambany rehefa manasitrana, ary ny adin-tsaina anatiny ateraky ny kely dia kely, izay manampy amin’ny fanatsarana ny hery miraikitra.

3. Fanasitranana mora. Misafidiana karazana mpitsabo isan-karazany, ny rafitra epoxy resin dia mety ho sitrana amin’ny maripana 0 ~ 180.

4. Fomba isan-karazany. Ny resins isan-karazany, ny mpitsabo, ary ny rafitra mpanova dia saika afaka mifanaraka amin’ny takian’ny fampiharana isan-karazany amin’ny endrika, ary ny elanelam-potoana dia azo avy amin’ny viscosity ambany dia ambany ka hatramin’ny solids point de poissant avo.

5. Mihena kely. Ny fanehoan-kevitra eo amin’ny resin epoxy sy ny mpitsabo dia ampiasaina amin’ny alàlan’ny fanehoan-kevitra miampy mivantana na ny valin’ny polymerization an’ny vondrona epoxy ao amin’ny molekiola resin, ary tsy misy rano na vokatra hafa miovaova navoaka. Raha ampitahaina amin’ny resins polyester tsy miangona sy resins phenolic dia mampiseho fihenam-bidy ambany (latsaky ny 2%) izy ireo mandritra ny fanasitranana.
