PC ipurasitiki yeinjiniya ine mashandiro akanaka kwazvo muzvinhu zvese. Ine mabhenefiti makuru mukudzivirira kukanganiswa, kudzivirira kupisa, kugadzikana kwechimiro uye kunonoka kwemurazvo. Saka, inoshandiswa zvakanyanya mumidziyo yemagetsi, mota, midziyo yemitambo nedzimwe nzvimbo. Zvisinei, PC molecular chains ine huwandu hwakawanda hwe benzene rings, izvo zvinoita kuti zviomere kuti ma molecular chains afambe, zvichikonzera kunyunguduka kukuru kwePC. Munguva yekugadzirisa, PC molecular chains inonamirwa. Mushure mekugadzirisa, mamwe ma molecular chains asina kubviswa zvachose muchigadzirwa anowanzo dzokera kumamiriro awo echisikigo, izvo zvinozokonzera kushushikana kwakawanda muzvigadzirwa zvakaumbwa nejekiseni rePC, zvichikonzera kutsemuka panguva yekushandiswa kana kuchengetwa kwechigadzirwa; panguva imwe chete, PC inyaya inonzwa kushoma. Kukanganisa uku kunoderedza kuwedzera kweMapurogiramu emakombiyuta.

Kuti PC ikwanise kugadzikana uye kupwanyika kwesimba rePC uye kugadzirisa mashandiro ayo, mishonga yekusimbisa inowanzo shandiswa kusimbisa PC. Parizvino, zvinhu zvinoshandiswa pakugadzirisa PC zvinosanganisa mishonga yekusimbisa (acrylate toughening agents) (ACR), methyl methacrylate-butadiene-styrene toughening agents (MBS) uye mishonga yekusimbisa inoumbwa nemethyl methacrylate se shell uye acrylate nesilicone se core. Mishonga iyi yekusimbisa inoenderana zvakanaka nePC, saka mishonga yekusimbisa inogona kuparadzirwa zvakaenzana muPC.

Pepa iri rakasarudza mhando shanu dzakasiyana dzezvinhu zvinosimbisa simba (M-722, M-732, M-577, MR-502 naS2001), uye rakaongorora mhedzisiro yezvinobatsira simba pahutano hwePC thermal oxidation aging properties, 70 ℃ water boiling aging properties, uye wet heat (85 ℃/85%) aging properties kuburikidza nekuchinja kwePC melt flow rate, heat deformation tembiricha uye mechanical properties.

Midziyo mikuru:

UP-6195: bvunzo yekuchembera kwekupisa kwakanyorova (kunyorova kwekupisa kwakanyanya uye kwakadereraimba yekuyedza kupisa);

UP-6196: bvunzo yekuchengetedza tembiricha yepamusoro (ovheni chaiyo);

UP-6118: bvunzo yekuvhunduka kwekupisa (kuvhunduka kwechando nekupisaimba yekuyedza);

UP-6195F: Kutenderera kwekupisa kwakanyanya uye kwakaderera kweTC (kamuri yekuyedza kushanduka kwekushisa nekukurumidza);

UP-6195C: bvunzo yekudedera tembiricha nehunyoro (makamuri matatu ekuyedza akakwana);

UP-6110: bvunzo yekushushikana kwakanyanya (kumanikidzwa kwakanyanyaimba yekuyedza yekukwegura);

UP-6200: bvunzo yekukwegura kweUV yezvinhu (kamuri yekuyedza kukwegura kweultraviolet);

UP-6197: bvunzo yekuora kwemushonga wemunyu (mushonga wemunyu).

Bvunzo yekushanda uye hunhu hwechimiro:

● Edza mwero wekuyerera kwehuwandu hwekunyunguduka kwezvinhu zvichienderana neISO 1133 standard, mamiriro ekuedzwa ndeye 300 ℃/1.2 kg;

● Edza simba rekudhonza uye kureba kwechinhu chacho pakaputsika zvichienderana neISO 527-1 standard, chiyero chekuyedza i50 mm/min;

● Edzai simba rekuchinjika uye modulus yekuchinjika kwezvinhu zvinoenderana neISO 178 standard, chiyero chekuyedza i2 mm/min;

● Edza simba rechinhu chacho rakachekwa zvichienderana neISO180 standard, shandisa muchina wekugadzira sample yenotch kugadzira notch yakaita se "V", kudzika kwenotch kuri 2 mm, uye sampuro yacho inochengetwa pa -30 ℃ kwemaawa mana bvunzo yenotch isati yaitwa;

● Edza tembiricha yekuchinja kwekupisa kwezvinhu zvinoenderana neISO 75-1 standard, mwero wekupisa uri 120 ℃/min;

●Bvunzo reYellowness index (IYI):Kureba kwedivi rekuumba jekiseni kwakakura kupfuura 2 cm, ukobvu i2 mm. Purati yemavara ine sikweya inoongororwa kuti iokisijeni ichengetwe, uye ruvara rwepurati yemavara isati yachengetwa uye mushure mekuchengetwa runoedzwa ne spectrophotometer. Chishandiso ichi chinofanira kuenzaniswa chisati chaedzwa. Purati yega yega yemavara inoyerwa katatu uye indekisi yeyero yepurati yemavara inonyorwa;

●Kuongorora kweSEM:Chidimbu chemuenzaniso chakaumbwa nejekiseni chinochekwa-chekwa, goridhe rinopfapfaidzwa pamusoro paro, uye chimiro charo pamusoro chinoonekwa pasi pemagetsi akati.
