Advantages of epoxy resin board
Bentahe ng epoxy resin board
1. Malakas na pagdirikit
Ang likas na polar hydroxyl group at ether bond sa molecular chain ng epoxy resin ay ginagawa itong lubos na nakadikit sa iba’t ibang mga substance. Ang pag-urong ng epoxy resin ay mababa kapag nagpapagaling, at ang panloob na stress na nabuo ay maliit, na tumutulong din upang mapabuti ang lakas ng pagdirikit.
2. Strong shrinkage
Ang reaksyon sa pagitan ng epoxy resin at ng curing agent na ginamit ay isinasagawa sa pamamagitan ng direktang karagdagan reaksyon o ring-opening polymerization reaction ng mga epoxy group sa resin molecule, at walang tubig o iba pang pabagu-bago ng produkto na inilalabas. Kung ikukumpara sa mga unsaturated polyester resins at phenolic resins, nagpapakita sila ng napakababang pag-urong (mas mababa sa 2%) sa panahon ng paggamot.
3. Electrical performance
The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance, and arc resistance.
4. Mga katangiang mekanikal
Ang cured epoxy resin system ay may mahusay na mekanikal na katangian.
5. Katatagan ng kemikal
Generally, the cured epoxy resin system has excellent alkali resistance, acid resistance and solvent resistance. Like other properties of the cured epoxy system, the chemical stability also depends on the selected resin and curing agent. Appropriate selection of epoxy resin and curing agent can make it have special chemical stability.
6. Dimensional stability
The combination of many of the above properties gives the epoxy resin system outstanding dimensional stability and durability.
7. mold resistance
The cured epoxy resin system is resistant to most molds and can be used in harsh tropical conditions.
