Ko izvi epoxy resin board zvigadzirwa

Resin, hardener, modifier masisitimu anowanikwa kuti aenderane nechero fomu rekunyorera rinodiwa, kubva kune yakaderera viscosities kusvika kune yakakwira melting point solids. Akasiyana siyana ekurapa anoshandiswa kurapa, uye epoxy resin system inogona kurapwa ingangoita tembiricha ye0 kusvika 180 ° C.

1. Kubatisisa kwakasimba

Kuvepo kwepolar hydroxyl uye ether bonds inherent in molecular chain of epoxy resin inoita kuti ive nekunamatira kwakanyanya kune zvakasiyana zvinhu. Epoxy resins ine yakaderera shrinkage panguva yekurapa uye kuderera kwemukati kushushikana, izvo zvinobatsirawo kuvandudza simba rekunamatira.

2. Kupfupisa kwakasimba

Kuita pakati peepoxy resin uye mushonga wekurapa unoshandiswa unoitwa kuburikidza nekuita kwekuwedzera kwakananga kana ring-inovhura polymerization reaction yeboka reepoxy muresin molecule, uye hapana mvura kana zvimwe zvinoputika by-zvigadzirwa zvinoburitswa. Vanoratidza kuderera kwakanyanya (pasi pe2%) panguva yekurapa zvichienzaniswa neunsaturated polyester resins uye phenolic resins.

3. Mechanical basa

Iyo yakaporeswa epoxy resin system ine yakanakisa mechaniki zvivakwa.

4. Basa remagetsi

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

5. Chemical kugadzikana

Kazhinji, iyo yakaporeswa epoxy resin system ine yakanakisa alkali kuramba, acid inodzivirira uye solvent kuramba. Kufanana nemamwe mabasa eakarapwa epoxy masisitimu, kugadzikana kwemakemikari kunoenderana neakasarudzwa resin uye mumiririri wekurapa. Sarudzo yakakodzera epoxy resin uye mumiririri wekurapa anogona kuita kuti ive yakakosha kugadzikana kwemakemikari basa.

6. Chikero kugadzikana

Iko kusanganiswa kwezvizhinji zvezviri pamusoro apa kunopa epoxy resin masisitimu yakanakisa dimensional kugadzikana uye kusimba.

7. Mold resistance

Yakarapirwa epoxy masisitimu inoshingirira kune akawanda mold uye inogona kushandiswa munzvimbo dzakaoma dzinopisa.
