Introduction to the characteristics of epoxy glass fiber board epoxy resin adhesive
Xususiyatlari bilan tanishtirish epoksi shisha tolali taxta epoxy resin adhesive
1. Qulay ishlov berish. Turli xil qattiqlashtiruvchi vositalarni tanlang, epoksi qatronlar tizimini deyarli 0 ~ 180 ℃ harorat oralig’ida davolash mumkin.
2. Mexanik xususiyatlar. Davolangan epoksi qatronlar tizimi mukammal mexanik xususiyatlarga ega.
3. Kuchli yopishish. Epoksi qatronlar molekulyar zanjiridagi qutbli gidroksil guruhlari va efir aloqalari uni turli moddalarga juda yopishqoq qiladi. Qattiqlashganda epoksi qatronining qisqarishi past bo’ladi va ichki stress kichik bo’ladi, bu ham yopishish kuchini yaxshilashga yordam beradi.
4. Low shrinkage. 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 emitted. Compared with unsaturated polyester resins and phenolic resins, they show very low shrinkage during curing.
5. Har xil shakllar. Har xil qatronlar, qotishtiruvchi moddalar va modifikator tizimlari qolipdagi turli xil ilovalarning talablariga deyarli moslasha oladi va diapazon juda past yopishqoqlikdan yuqori erish nuqtasiga qadar bo’lishi mumkin.
