Nhanganyaya kune iyo application inoshanda maitiro epoxy girazi fiber board

Epoxy girazi faibha bhodhi, epoxy phenolic laminated girazi jira bhodhi, epoxy resin kazhinji inoreva organic polymer makomisheni ane maviri kana anopfuura mapoka epoxy mumorekuru, kunze kwevamwe, iwo mamorekuru mamorekuru haana kukwirira. Iyo molecular structure ye epoxy resin inoratidzirwa neboka rinoshanda epoxy muketani ye molecular. Iro 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.

Epoxy girazi fiber bhodhi application maitiro uye mabasa:

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

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. 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.

5. 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.
