Ndeapi maitiro e epoxy resin board?

Epoxy resin board inonziwo insulation board, epoxy glass fiber board, 3240 epoxy glass fiber board. Epoxy resin inoreva organic polymer makomisheni ane maviri kana anopfuura mapoka epoxy mumorekuru. Hukama hwema molecular moles hauna kukwirira. Iyo molecular structure ye epoxy resin inoratidzirwa neboka rinoshanda epoxy muketani ye molecular. Iyo epoxy boka rinogona kuwanikwa kumagumo, pakati kana mune cyclic chimiro cheiyo molecular chain. Nekuti iyo molecular chimiro ine anoshanda epoxy mapoka, anogona kuita muchinjiko-inobatanidza maitiro nemhando dzakasiyana dzeanorapa maajenti kuti aumbe asinganyunguke uye asingafusike mapolymer ane nzira nhatu network.

Marezeni akasiyana, anorapa maajenti, uye anogadzirisa masisitimu anogona kupotsa anoenderana nezvinodiwa zveakasiyana mashandisirwo pafomu, uye huwandu hunogona kubva kubva zvakanyanya kuderera viscosity kusvika kune yakakwira melting point solids. Akasiyana siyana ekurapa anoshandiswa kudivi rekurapa, uye iyo epoxy resin system inogona kupotsa kurapwa mutembiricha ye0 ~ 180 ℃.

1, kunamatira kwakasimba

Kuvepo kwepolar hydroxyl uye ether bond inogara mune molecular cheni ye epoxy resin inoita kuti ive nekunamatira kwakanyanya kune zvakasiyana zvinhu. Iyo shrinkage ye epoxy resin yakaderera kana ichirapa, uye kushushikana kwemukati kunogadzirwa kudiki, izvo zvinobatsirawo kuvandudza kusimba kwekunamatira.

2, chibvumirano chakasimba

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

3, michina zvinhu

Iyo yakaporeswa epoxy resin system ine yakanakisa mechaniki zvivakwa.

4, kushanda kwemagetsi

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

5, kugadzikana kwemakemikari

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 zviri pamusoro zvinoita kuti epoxy resin system ive nekudzikama kwechimiro uye kusimba.

7, inopikisa mold

Iyo yakarapwa epoxy resin system inoshingirira kune akawanda mold uye inogona kushandiswa pasi pekupisa kwemamiriro ekunze.
