Izindaba

I-PC uhlobo lwepulasitiki yobunjiniyela olusebenza kahle kakhulu kuzo zonke izici. Inezinzuzo ezinkulu ekumelaneni nokushayisana, ukumelana nokushisa, ukuzinza kobukhulu bokubumba kanye nokuvinjelwa komlilo. Ngakho-ke, isetshenziswa kabanzi ezintweni zikagesi, ezimotweni, emishinini yezemidlalo nakwezinye izinkambu. Kodwa-ke, amaketanga e-PC aqukethe inani elikhulu lamasongo e-benzene, okwenza kube nzima ukuthi amaketanga e-molecule ahambe, okuholela ekuncibilikeni okukhulu kwe-PC. Ngesikhathi senqubo yokucubungula, amaketanga e-PC aqondiswe. Ngemva kokucubungula, amanye amaketanga e-molecule angakashintshi ngokuphelele emkhiqizweni avame ukubuyela esimweni sawo semvelo, okuzobangela inani elikhulu lokucindezeleka okusele emikhiqizweni ebunjiwe ejoyintiwe yi-PC, okuholela ekuqhekekeni ngesikhathi sokusetshenziswa noma ukugcinwa komkhiqizo; ngesikhathi esifanayo, i-PC iyinto ezwela kakhulu. Lokhu kusilela kunciphisa ukwanda okuqhubekayo kweIzinhlelo zokusebenza ze-PC.

Ukuze kuthuthukiswe ukuzwela kwe-notch kanye nokuqhekeka kokucindezeleka kwe-PC futhi kuthuthukiswe ukusebenza kwayo kokucubungula, ama-toughening agents avame ukusetshenziselwa ukuqinisa i-PC. Njengamanje, izithasiselo ezivame ukusetshenziswa ekuguqulweni kokuqina kwe-PC emakethe zifaka ama-acrylate toughening agents (ACR), ama-methyl methacrylate-butadiene-styrene toughening agents (MBS) kanye nama-toughening agents akhiwe yi-methyl methacrylate njengegobolondo kanye ne-acrylate kanye ne-silicone njengengqikithi. Lawa ma-toughening agents anokuhambisana okuhle ne-PC, ngakho-ke ama-toughening agents angasakazwa ngokulinganayo kwi-PC.

Leli phepha likhethe izinhlobo ezi-5 ezahlukene zama-toughening agents (M-722, M-732, M-577, MR-502 kanye ne-S2001), futhi lahlola imiphumela yama-toughening agents kwizakhiwo zokuguga ze-PC thermal oxidation, izakhiwo zokuguga ezibilayo ezingama-70 ℃, kanye nezakhiwo zokuguga zokushisa okumanzi (85 ℃/85%) ngokushintsha kwesilinganiso sokugeleza kokuncibilika kwe-PC, izinga lokushisa lokuguquguquka kokushisa kanye nezakhiwo zemishini.

Imishini eyinhloko:

UP-6195: isivivinyo sokuguga kokushisa okumanzi (okumanzi okushisa okuphezulu nokuphansiigumbi lokuhlola ukushisa);

UP-6196: ukuhlolwa kokugcina ukushisa okuphezulu (ihhavini elinembile);

UP-6118: ukuhlolwa kokushaqeka kwezinga lokushisa (ukushaqeka okubandayo nokushisaigumbi lokuhlola);

UP-6195F: Umjikelezo wokushisa ophezulu nophansi we-TC (igumbi lokuhlola lokushintsha kokushisa okusheshayo);

UP-6195C: ukuhlolwa kokudlidliza kokushisa nomswakama (amakamelo amathathu okuhlola aphelele);

UP-6110: ukuhlolwa kokucindezeleka okusheshisiwe okuphezulu (ukusheshiswa kokucindezeleka okuphezuluigumbi lokuhlola ukuguga);

UP-6200: ukuhlolwa kokuguga kwe-UV okubonakalayo (igumbi lokuhlola ukuguga kwe-ultraviolet);

UP-6197: ukuhlolwa kokugqwala kwesifutho sikasawoti (igumbi lokuhlola isifutho sikasawoti).

Ukuhlolwa kokusebenza kanye nokucaciswa kwesakhiwo:

● Hlola izinga lokugeleza kwesisindo sokuncibilika kwezinto ngokwezinga le-ISO 1133, isimo sokuhlola singama-300 ℃/1.2 kg;

● Hlola amandla okuthamba kanye nokwelulwa lapho impahla iphuka ngokwezinga le-ISO 527-1, izinga lokuhlola lingu-50 mm/min;

● Hlola amandla okugoba kanye ne-flexural modulus yezinto ezibonakalayo ngokwezinga le-ISO 178, izinga lokuhlola lingu-2 mm/min;

● Hlola amandla omthelela onamachashazi wezinto ezibonakalayo ngokwezinga le-ISO180, sebenzisa umshini wokwenza isampula yamachashazi ukuze ulungiselele ichashazi elinomumo "we-V", ukujula kwechashazi kungu-2 mm, futhi isampula igcinwa ku--30 ℃ amahora ama-4 ngaphambi kokuhlolwa komthelela ophansi;

● Hlola izinga lokushisa lokuguquguquka kokushisa kwezinto ngokwezinga le-ISO 75-1, izinga lokushisa lingu-120 ℃/min;

●Ukuhlolwa kwenkomba ye-Yellowness (IYI):Ubude bohlangothi lokubumba ngomjovo bukhulu kuno-2 cm, ubukhulu bungu-2 mm. Ipuleti lombala oyisikwele lihlolwa ukuguga kwe-oxygen okushisa, futhi umbala wepuleti lombala ngaphambi nangemva kokuguga uhlolwa nge-spectrophotometer. Ithuluzi lidinga ukulinganiswa ngaphambi kokuhlolwa. Ipuleti ngalinye lombala lilinganiswa izikhathi ezintathu futhi inkomba ephuzi yepuleti lombala iqoshwe phansi;

●Ukuhlaziywa kwe-SEM:Umugqa wesampula obunjiwe ngomjovo uyasikwa, igolide lifuthwa ebusweni balo, futhi ukuma kwalo ebusweni kubonwa ngaphansi kwe-voltage ethile.
