Giredhi kupatsanura tsananguro ye epoxy nebwe kuputira bhodhi
Epoxy resins kazhinji inoreva kune organic organic polymer makomputa ane maviri kana anopfuura epoxy mapoka mumorekuru. Kunze kweavo vashoma, avo akaenzana mamorekuru masamu haana kukwirira. Iyo mamorekuru mamiriro epoxy resin inoratidzirwa neiyo inoshanda epoxy boka muketani yemakemikari. Epoxy boka rinogona kuwanikwa pamagumo, pakati kana mune cyclic chimiro checheni yemolekyuli. Nekuti iyo mamorekuru chimiro chine anoshanda epoxy mapoka, ivo vanogona kupinda muchinjika-kubatanidza maitiro nemhando dzakasiyana dzekuporesa vamiririri kuti vagadzire asingasviki uye asingachinjiki ma polymers ane matatu-nzira network dhizaini.
Kushanda hunhu epoxy nebwe kuputira bhodhi
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.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.
6. Kuita kwemagetsi. Iyo yakaporeswa epoxy resin system inoyevedza insulating zvinhu neakakwira dielectric zvivakwa, pamusoro leakage kuramba, uye arc kuramba.
7. Kugadzikana kwemakemikari. Kazhinji, iyo yakaporeswa epoxy nebwe system ine yakanakisa alkali kuramba, acid nemishonga uye solvent kuramba. Kunge zvimwe zvimiro zveiyo yakaporeswa epoxy system, iko kugadzikana kwemakemikari kunoenderana nesarudzo yakasarudzwa uye inorapa mumiririri. Sarudzo yakakodzera ye epoxy resin uye inorapa mumiririri inogona kuita kuti ive neakasarudzika makemikari kugadzikana.
8. Chimiro chakadzikama. Iko kusanganiswa kwezvakawanda zvezvinhu zviri pamusoro apa kunopa iyo epoxy resin system yakatanhamara kuenzana kugadzikana uye kusimba.
9. Resistant kuumbwa. Iyo yakaporeswa epoxy resin system inopesana neakawanda mafuru uye inogona kushandiswa munzvimbo dzakashata dzinopisa.
Nyora kupatsanura
Zvinoenderana neyakaumbwa mamorekuru, epoxy resini inogona kuve yakakamurwa kuita zvikamu zvishanu:
1. Glycidyl ether epoxy nebwe
2. Glycidyl ester epoxy nebwe
3. Glycidylamine epoxy nebwe
4. Linear aliphatic epoxy resin
5. Alicyclic epoxy nebwe
