Kuita kwe epoxy resin kugadzirisa

1. Zvimiro zvakasiyana-siyana. Marezeni akasiyana, anorapa maajenti, uye magadzirirwo masisitimu anogona kupotsa anoenderana nezvinodiwa zveakasiyana mashandisirwo pafomu, uye huwandu hunogona kubva kubva zvakanyanya kuderera viscosity kusvika kune yakakwira melting point solids.

2.Kurapa kuri nyore. Sarudza akasiyana akasiyana ekurapa vamiririri, iyo epoxy nebwe system inogona kupora mune yekushisa renji ye0 ~ 180 ℃.

3. Kubatisisa kwakasimba. Iwo epakutanga polar hydroxyl mapoka uye ether zvisungo mumoleketani cheni ye epoxy resins inoita kuti inyatsoomerera kune akasiyana zvinhu. Iyo shrinkage ye epoxy resin yakaderera pakurapa, uye kunetsekana kwemukati kunogadzirwa idiki, iyo inobatsirawo kugadzirisa simba rekunamatira.

4. Yakaderera shrinkage. Mhinduro pakati pe epoxy resin uye iyo inorapa mumiririri inoshandiswa inoitwa nekuwedzera kuwedzera kuita kana kuvhurira-kuvhura polymerization maitiro emapoka epoxy mune resini morekuru, uye hapana mvura kana zvimwe zvisina kugadzikana nezvigadzirwa zvinoburitswa. Zvichienzaniswa neasaturated polyester resin uye phenolic resins, ivo vanoratidza yakaderera kwazvo shrinkage (isingasviki 2%) panguva yekurapa.

5. Zvokuimba. Iyo yakaporeswa epoxy resin system ine yakanakisa michina zvivakwa.
