Sezvinyorwa zvechinyorwa,isina kusimbiswa polyester resinYashandiswa chaizvo mumakonzo, girazi fiber yakasimbiswa mapurasitiki, dombo rekunyepedzera, rombo rakanaka, uye mamwe minda. Nekudaro, iyo ruvara rwellowing yemazwi asina kugadzikana agara ari dambudziko kune vagadziri. Sekureva kwenyanzvi, izvo zvakajairika zvinokonzeresa yero yetsvina isina kusimbiswa nzvimbo inosanganisira zvinotevera:
1. Munguva yekukudzwa kweSynthesis yekukonzeresa, nekuda kweiyo yekukwira kwero yero, tembiricha yakanyanya Kuwedzera kuchembera, kunokanganisa kutaridzika kwezvinhu zvigadzirwa.
2.. makomisheni ekupisa kwakanyanya. Kushatisa, kunowanzoita shanduko yemagetsi, kugadzira yero.
3. Mukuita kwekugadzira kugadzirwa, zvigadzirwa zvemidziyo zvinowanikwa neokisijeni nekuda kwekuita kwevarombo kuita chishandiso. Kaini yeMolecular yePolyspezed Polyester haina chete mapoka ester chete, mapoka emeridian, uye mapoka antentope, asiwo zvisungo zviviri uye zvindori zvinetso. Iyo inova neyakaora oxidative degradation, uye iko kuoneka kwekuita ndiko kuti ruvara rwechiratidzo runotendeuka yero.
4. Iyo pesvedzero yekuzvidzwa senge antioxidants, polmerization inhibitors, kurapa mumiriri, etc. Amine antioxidants inotsaurwa nyore nyore muNitroxide yemahara radicals kuti uvhorwe chigadzirwa. Kazhinji inoshandiswa polymerization inhibitors, yakadai se hydroquinone, ndeyako oxidation mu quinones pamberi pemapfungwaoni, iyo yavachaita ruvara, nekudaro ichikanganisa ruvara rwe resin. Vamwe vagadziri vekurapa vamiririri vachiri kushandisa acyl peeroxide-tertiary amine masystem uye ketone peroxide simbi sofa sights. Mavara, nyore-kune-ruvara resin.
Ehe, pane zvimwe zvikonzero zvinoita kuti resin itendeuke. Kazhinji kutaura, ori-okisijeni okisijeni uye ultraviolet rays ndizvo zvikonzero zvikuru zveyero. Yakakwana dibasic acid (kana acid anthydride) inoshandiswa pachinzvimbo chekushandiswa kwesic ( Mutengo, iyi nzira haina kunaka.
Sekureva kwenyanzvi, kuwedzera pakuzadza Inert Gasi mukugadzira uye yekuchengetedza maitiro kuti uwedzere kunakisa uye ultravioled anodzivirira iyo yebhuruu polyester. Nyanzvi-Yakakurudzirwa Inti-yellowing mhinduro yeiyo isina kusimbiswa resins ndeye:
Antioxidants iyo isina maAmines anosarudzwa, uye yekutanga uye yebetsero yeAntioxidants inoshandiswa musanganiswa. Iyo yekutanga antioxicidenlant inowanzo dzivisa zvimiti, iyo inogona kutora peroxide yemahara radicals; Iyo Auxialary Abixidants idzo phosphite, iyo ichiri kushatisa hydropophereroxide, inogona zvakare kutadza simbi ioni kudzivirira iyo resin kubva kune oxidative discoloration. Kana iwe uchida kuenderera mberi nekuwedzera kudzikisira kweyero uye kupokana kwemamiriro ekunze, zvinokurudzirwa kuwedzera uv nyaradzo. Kuwedzera UV Bvisa zvinobatsira zvinobudirira phenomenon yePolenommy zvinhu pasi pechigadzirwa cheLollmer yechigadzirwa, uye ine yakanaka synergistic maitiro kana ichishandiswa pamwe chete neAndiyoxidants. Ehezve, kushandiswa kweAntioxidants uye UV AVEROBERS hazvigone kugadzirisa dambudziko reWilleing zvigadzirwa zvePolyter. giredhi.
Eduisina kusimbiswa polyester inotisa nzvimboinowanikwa mumhando dzakasiyana siyana, pamwe neye-yellowing resins, seinotevera:
Isu tinogadzira zvakarefiberglass zvakananga kudzima,fiberglass mats, fiberglass mesh, uyefiberglass yakarukwa.
