zvakanakira epoxy resin board

1. Kubatisisa kwakasimba

Iwo echisikigo polar hydroxyl mapoka uye ether zvisungo mune molecular cheni ye epoxy resins inoita kuti inamire zvakanyanya kune zvakasiyana zvinhu. Iyo shrinkage ye epoxy resin yakaderera kana ichirapa, uye kushushikana kwemukati kunogadzirwa kudiki, izvo zvinobatsirawo kuvandudza kusimba kwekunamatira.

2. Kuderera kwakasimba

Kuita pakati peepoxy resin uye mumiririri wekurapa anoshandiswa anoitwa nekunangana kwekuwedzera reaction kana ring-kuvhura polymerization reaction yemapoka epoxy mumorekuru resin, uye hapana mvura kana zvimwe zvinoputika by-zvigadzirwa zvinoburitswa. Kuenzaniswa neunsaturated polyester resins uye phenolic resins, dzinoratidza kuderera kwakanyanya (pasi pe2%) panguva yekurapa.

3. Kuita kwemagetsi

Iyo yakaporeswa epoxy resin system ndeye yakanakisa insulating zvinhu ine yakakwira dielectric zvivakwa, pamusoro pekudonha kwekudzivirira, uye arc kuramba.

4. Mechanical properties

Iyo yakaporeswa epoxy resin system ine yakanakisa mechaniki zvivakwa.

5. Chemical kugadzikana

Kazhinji, iyo yakaporeswa epoxy resin system ine yakanakisa alkali kuramba, acid inodzivirira uye solvent kuramba. Kufanana nezvimwe zvimiro zveyakarapwa epoxy system, iyo kemikari kugadzikana kunoenderanawo neakasarudzwa resin uye mumiririri wekurapa. Kusarudzwa kwakakodzera kwe epoxy resin uye mumiririri wekurapa anogona kuita kuti ive yakakosha kugadzikana kwemakemikari.

6. Dimensional kugadzikana

Iko kusanganiswa kwezvizhinji zvezvivakwa pamusoro apa kunopa epoxy resin system yakasarudzika kugadzikana uye kusimba.

7. mold resistance

Iyo yakaporeswa epoxy resin system inoshingirira kune akawanda mold uye inogona kushandiswa munzvimbo dzinopisa dzinopisa.
