What are the advantages and disadvantages of 3240 epoxy resin board

3240 epoxy resin board advantages

1. Mhando dzakasiyana. Mhando dzakasiyana dzeinsheni, dzinorapa vamiririri, uye modifier masisitimu anogona kunge anoenderana nezvinodiwa zvekushandisa kwakasiyana pafomu, uye huwandu hunogona kunge huchibva kune yakaderera viscosity kusvika kumusoro kwakanyunguduka nzvimbo dzakasimba.

2. 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.

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

4. Kuderera kwakaderera. Mhedzisiro pakati peepoxy resin uye mumiririri wekurapa anoshandiswa anoitwa nekunangana kwekuwedzera reaction kana mhete-inovhura polymerization maitiro epoxy mapoka muresin molecule, uye hapana mvura kana zvimwe zvinoputika by-zvigadzirwa zvinoburitswa. Zvichienzaniswa neunsaturated polyester resins uye phenolic resins, dzinoratidza kuderera kwakanyanya (pasi pe2%) panguva yekurapa.

5. Kuita kwemagetsi. Iyo yakaporeswa epoxy resin system inoyevedza insulating zvinhu neakakwira dielectric zvivakwa, pamusoro leakage kuramba, uye arc kuramba.

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

Disadvantages of epoxy resin board
