I-PC luhlobo lweplastiki yobunjineli enomsebenzi ogqwesileyo kuzo zonke iinkalo. Inezibonelelo ezinkulu ekuchaseni impembelelo, ukumelana nobushushu, ukuzinza kobukhulu bokubumba kunye nokungalali. Ke ngoko, isetyenziswa kakhulu kwizixhobo ze-elektroniki, iimoto, izixhobo zemidlalo nakwezinye iindawo. Nangona kunjalo, ii-PC molecular chains ziqulathe inani elikhulu lee-benzene rings, nto leyo eyenza kube nzima ukuba ii-molecular chains zihambe, nto leyo ebangela ukuba i-PC ibe ne-melt viscosity enkulu. Ngexesha lenkqubo yokucubungula, ii-PC molecular chains ziyajongwa. Emva kokucubungula, ezinye zee-molecular chains ezingasuswanga ngokupheleleyo kwimveliso zihlala zibuyela kwimeko yazo yendalo, nto leyo eya kubangela uxinzelelo olukhulu olushiyekileyo kwiimveliso ezibunjiweyo ze-PC injection, nto leyo eya kubangela ukuqhekeka ngexesha lokusetyenziswa okanye ukugcinwa kwemveliso; kwangaxeshanye, i-PC yinto ebuthathaka. Ezi ntsilelo zithintela ukwanda okungakumbiUsetyenziso lwePC.

Ukuze kuphuculwe uvakalelo lwe-notch kunye nokuqhekeka koxinzelelo lwe-PC kunye nokuphucula ukusebenza kwayo kokucubungula, ii-toughening agents zihlala zisetyenziselwa ukuqinisa i-PC. Okwangoku, izongezo ezisetyenziswa rhoqo ekuguquleni i-PC toughening agents kwimarike ziquka ii-acrylate toughening agents (ACR), i-methyl methacrylate-butadiene-styrene toughening agents (MBS) kunye nee-toughening agents ezenziwe yi-methyl methacrylate njengeqokobhe kunye ne-acrylate kunye ne-silicone njengesiseko. Ezi arhente zokuqinisa zihambelana kakuhle ne-PC, ngoko ke ii-agent zokuqinisa zinokusasazwa ngokulinganayo kwi-PC.

Eli phepha likhethe iintlobo ezi-5 ezahlukeneyo zee-toughening agents (M-722, M-732, M-577, MR-502 kunye ne-S2001), laza lavavanya imiphumo yee-toughening agents kwiipropati zokuguga ze-PC thermal oxidation, iipropati zokuguga ezibilayo ezingama-70 ℃, kunye neepropati zokuguga ezimanzi (85 ℃/85%) ngokutshintsha izinga lokuhamba kwe-PC melt, ubushushu bokuguquguquka kobushushu kunye neepropati zoomatshini.

Izixhobo eziphambili:

UP-6195: uvavanyo lokwaluphala kobushushu obumanzi (ubushushu obuphezulu nobuphantsi bumanziigumbi lovavanyo lobushushu);

UP-6196: uvavanyo lokugcina ubushushu obuphezulu (i-oven echanekileyo);

UP-6118: uvavanyo lomothuko wobushushu (umothuko obandayo noshushuigumbi lovavanyo);

UP-6195F: Umjikelo wobushushu obuphezulu nobuphantsi be-TC (igumbi lovavanyo lokutshintsha kobushushu ngokukhawuleza);

UP-6195C: uvavanyo lokungcangcazela kobushushu kunye nokufuma (amagumbi amathathu ovavanyo apheleleyo);

UP-6110: uvavanyo loxinzelelo olukhawulezileyo oluphezulu (uxinzelelo oluphezulu lukhawulezileyoigumbi lokuvavanya ukuguga);

UP-6200: uvavanyo lokuguga lwe-UV (igumbi lokuvavanya ukuguga nge-ultraviolet);

UP-6197: uvavanyo lokugqwala kwesitshizi setyuwa (igumbi lovavanyo lwesitshizi setyuwa).

Uvavanyo lokusebenza kunye nokuchazwa kwesakhiwo:

● Vavanya izinga lokuhamba kobunzima bokunyibilika kwezinto ngokwemigangatho ye-ISO 1133, imeko yovavanyo yi-300 ℃/1.2 kg;

● Vavanya amandla okutsalwa kunye nokwandiswa xa izinto ziqhekeka ngokwemigangatho ye-ISO 527-1, izinga lovavanyo yi-50 mm/min;

● Vavanya amandla e-flexural kunye ne-flexural modulus yezinto ezisetyenziswayo ngokwemigangatho ye-ISO 178, izinga lovavanyo yi-2 mm/min;

● Vavanya amandla empembelelo eqingqiweyo yezinto ezisetyenzisiweyo ngokwemigangatho ye-ISO180, sebenzisa umatshini wokwenza isampuli ye-notch ukulungiselela i-notch efana ne-"V", ubunzulu be-notch yi-2 mm, kwaye isampuli igcinwa kwi--30 ℃ kangangeeyure ezi-4 ngaphambi kovavanyo lwempembelelo yobushushu obuphantsi;

● Vavanya ubushushu bokuguqulwa kobushushu bezinto ngokwemigangatho ye-ISO 75-1, izinga lokufudumeza liyi-120 ℃/min;

●Uvavanyo lwe-Yellowness index (IYI):Ubude becala lokubumba ngenaliti bukhulu kune-2 cm, ubukhulu buyi-2 mm. Ipleyiti yombala osikwere ivavanywa ngokuguga kweoksijini eshushu, kwaye umbala wepleyiti yombala ngaphambi nasemva kokuguga uvavanywa nge-spectrophotometer. Isixhobo kufuneka silinganiswe ngaphambi kokuvavanywa. Ipleyiti nganye yombala ilinganiswa kathathu kwaye isalathisi esityheli sepleyiti yombala siyarekhodwa;

●Uhlalutyo lwe-SEM:Umcu wesampulu otyhidiweyo ngenaliti uyasikwa, igolide itshizwa kumphezulu wayo, kwaye imo yomphezulu wayo ibonwa phantsi kombane othile.
