Sezvinhu zvakasanganiswa,resin yepolyester isina kugutarave richishandiswa zvakanaka mukugadzira machira, mapurasitiki akasimbiswa nefiber yegirazi, matombo ekugadzira, mabasa emaoko, nedzimwe nzvimbo. Zvisinei, ruvara rweyero rwemaresini asina kuguta rwagara rwuri dambudziko kune vagadziri. Sekureva kwenyanzvi, zvikonzero zvinowanzoita kuti maresini asina kuguta ave yero zvinosanganisira zvinotevera:

1. Munguva yekugadzira resin isina kuguta, nekuda kwekukwegura kwekupisa kunokonzerwa nekupisa kwakanyanya, tembiricha yekupisa yeresin isina kuguta inosvika 180 ~ 220 ° kana kupfuura, pakupisa uku resin iri nyore kutsvukira nekuda kwekukwegura kwekupisa, zvichikanganisa chitarisiko chezvigadzirwa zveresin.

2. Kutsvuka kweyero kunokonzerwa nekuratidzwa kweresin kumwaranzi ye ultraviolet kunonyanya kukonzerwa nekuvapo kwemaringi ebenzene muresin (kusanganisira aromatic dibasic acids/anhydride uye maringi ebenzene anounzwa ne styrene), izvo zvinogona kunge zvichikonzerwa nekupiswa kwemakemikari anonhuhwirira pakupisa kwakanyanya. Kuora, kunowanzo shanduka nemagetsi, zvichiita kuti resin ive yeyero.

3. Mukugadzirwa kweresin, zvinhu zvakagadziriswa zvinosangana neokisijeni nekuda kwekusashanda zvakanaka kwesefa kwemudziyo. Cheni yemolecular yepolyester isingasanganisike ine kwete mapoka eester chete, mapoka emeridian, uye mapoka eantelope, asiwo mabhondi maviri uye mhete dzinonhuhwirira. Inoparadzwa nekupisa kweoxidative, uye kushanda kuri pachena ndekwekuti ruvara rweresin runoshanduka kuita yero.

4. Simba rezvinhu zvinowedzerwa zvakaita se antioxidants, polymerization inhibitors, curing agents, nezvimwewo. Amine antioxidants inoshandurwa nyore nyore kuita nitrooxide free radicals kuti ipe ruvara rwechigadzirwa. Zvinoshandiswa zvakanyanya mu polymerization inhibitors, zvakaita se hydroquinone, zvinonzi Oxidation mu quinones kana paine quinones, idzo dzine ruvara, nokudaro zvichikanganisa ruvara rwe resin. Vamwe vagadziri ve curing agents vachiri kushandisa acyl peroxide-tertiary amine systems uye ketone peroxide metal sipo systems. Resin ine ruvara, iri nyore kushandisa ruvara.

Ehe, kune zvimwe zvikonzero zvinoita kuti resin iite yero. Kazhinji, okisijeni inopisa uye mwaranzi ye ultraviolet ndizvo zvikonzero zvikuru zvinoita kuti iite yero. Dibasic acid yakaguta (kana acid anhydride) inoshandiswa panzvimbo pearomatic dibasic acid (kana acid anhydride), kunyange zvazvo ichigona kushandiswa kusvika pamwero wakati, ruvara rweresin runogona kuitwa kuti ruve rwakareruka, asi tichifunga nezvezvinhu zvakasiyana-siyana zvakaita sekushanda kweresin uye mutengo wayo, nzira iyi haina kunaka.

Sekureva kwenyanzvi, pamusoro pekuzadza gasi risina simba mukugadzirwa nekuchengetwa kwemhepo kudzivirira kusangana neokisijeni zvakanyanya sezvinobvira, nzira inoshanda ndeyekuwedzera ma antioxidants nema ultraviolet absorbers, izvo zvinogona kudzivirira kutsvuka kwepolyester yakanonoka. Mhinduro dzinokurudzirwa nenyanzvi dzekudzivirira kutsvuka kwemafuta emaresini asina kuguta ndeidzi:

Maantioxidant asina maamine anosarudzwa, uye maantioxidant ekutanga neanobatsira anoshandiswa pamwe chete. Maantioxidant ekutanga anowanzo vharirwa maphenols, anogona kubata peroxide free radicals; maantioxidant anobatsira maphosphites, ayo Paunenge uchiora hydroperoxide, inogonawo kuchenesa maion esimbi kudzivirira resin kubva mukuora kweoxidative. Kana uchida kuwedzera kuvandudza kuramba kweyero uye kuramba kwemamiriro ekunze, zvinokurudzirwa kuwedzera UV absorber. Kuwedzera UV absorber kunogona kudzivirira zvinobudirira chiitiko chekuyero kwezvinhu zvepolymer pasi pesimba remwaranzi ye ultraviolet, uye kupa dziviriro yakanaka kune chigadzirwa, zvichidzivirira zvinobudirira Kuderedzwa kwe gloss, kugadzirwa kwe cracks, bubbles, uye delamination zvinogona kuvandudza zvakanyanya kuramba kwemamiriro ekunze kwechigadzirwa, uye zvine simba rakanaka re synergistic kana zvikashandiswa pamwe chete nema antioxidants. Ehe, kushandiswa kwe antioxidants uye UV absorbers hakugone kugadzirisa dambudziko rekuyero, asi mukati meimwe nzira, inogona kudzivirira zvinobudirira oxidative yellowing yezvigadzirwa zve polyester zvisina kuguta, kuchengetedza watercolor yechigadzirwa ichi pachena, uye kuvandudza mhando yechigadzirwa.

Yedumaresini epolyester asina kugutaanowanikwa mumhando dzakasiyana-siyana, pamwe chete nemaresini asiri eyero, seizvi:

Isu tinogadzirawofiberglass kutungamira zvakananga,mameti efiberglass, mesh yefiberglass, uyefiberglass yakarukwa inofamba-famba.
