Epoxy resin board use characteristics

1. Siffofin daban-daban

Daban-daban resins, masu warkarwa, da tsarin gyarawa na iya kusan daidaitawa da buƙatun aikace-aikace daban-daban akan sigar, kuma kewayon na iya zama daga ƙarancin ɗanko zuwa babban madaidaicin narkewa.

2. Ƙarfin mannewa

Ƙungiyoyin hydroxyl na polar da ke da alaƙa da ether bond a cikin sarkar kwayoyin halitta na resin epoxy suna sa shi manne sosai ga abubuwa daban-daban. Rashin raguwar resin epoxy yana da ƙananan lokacin da ake warkewa, kuma damuwa na ciki da aka haifar yana da ƙananan, wanda kuma yana taimakawa wajen inganta ƙarfin mannewa.

3. Magance mai dacewa

Zaɓi nau’ikan magunguna daban-daban, tsarin resin epoxy kusan ana iya warkewa a cikin kewayon zafin jiki na 0 ~ 180 ℃.

4. Ƙananan raguwa

The reaction between the epoxy resin and the curing agent used is carried out by direct addition reaction or ring-opening polymerization reaction of epoxy groups in the resin molecule, and no water or other volatile by-products are released. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage (less than 2%) during curing.
