PC ke mofuta oa polasetiki ea boenjiniere e nang le ts'ebetso e ntle haholo likarolong tsohle. E na le melemo e meholo ea ho hanyetsa tšusumetso, ho hanyetsa mocheso, ho theha botsitso ba sebopeho le ho lieha ha lelakabe. Ka hona, e sebelisoa haholo lisebelisoa tsa elektroniki, likoloi, lisebelisoa tsa lipapali le masimong a mang. Leha ho le joalo, liketane tsa limolek'hule tsa PC li na le palo e kholo ea mehele ea benzene, e etsang hore ho be thata hore liketane tsa limolek'hule li tsamaee, e leng se etsang hore ho be le viscosity e kholo ea ho qhibiliha ha PC. Nakong ea ts'ebetso, liketane tsa limolek'hule tsa PC li sekametse. Ka mor'a ho sebetsa, tse ling tsa liketane tsa limolek'hule tse sa hloekang ka ho feletseng sehlahisoa li atisa ho khutlela boemong ba tsona ba tlhaho, e leng se tla etsa hore ho be le khatello e ngata ea masala ka lihlahisoa tse entsoeng ka ente ea PC, tse hlahisang mapetsong nakong ea tšebeliso ea lihlahisoa kapa polokelo; ka nako e ts'oanang, PC ke thepa e sa utloeng bohloko. Mefokolo ena e fokotsa katoloso e eketsehileng eaLisebelisoa tsa PC.

Bakeng sa ho ntlafatsa kutloisiso ea "notch" le khatello ea maikutlo ea PC le ho ntlafatsa ts'ebetso ea eona ea ts'ebetso, hangata li-agents tse thata li sebelisoa ho thatafatsa PC. Hajoale, litlatsetso tse sebelisoang hangata bakeng sa phetoho e thata ea PC 'marakeng li kenyelletsa li-acrylate toughening agents (ACR), methyl methacrylate-butadiene-styrene toughening agents (MBS) le li-toughening agents tse entsoeng ka methyl methacrylate joalo ka khetla le acrylate le silicone e le mantlha. Lisebelisoa tsena tse thata li na le kamano e ntle le PC, kahoo li-agents tse thata li ka qhalakanngoa ka ho lekana ho PC.

Pampiri ena e khethile mefuta e 5 e fapaneng ea li-agent tse toughening (M-722, M-732, M-577, MR-502 le S2001), 'me ea lekola litlamorao tsa lisebelisoa tse thatafatsang thepa ea botsofali ea PC, 70 ℃ metsi a belang botsofali, le mocheso o mongobo (85 ℃/85%) thepa ea botsofali ka liphetoho tsa PC qhibiliha lebelo la phallo, mocheso deformation mocheso le thepa mechine.

Lisebelisoa tsa mantlha:

UP-6195: teko ea botsofali ea mocheso o metsi (mocheso o phahameng le o tlase o kolobilekamore ea teko ea mocheso);

UP-6196: teko ea polokelo ea mocheso o phahameng (ovine e nepahetseng);

UP-6118: Teko ea ho tšoha ha mocheso (mohatsela o batang le o chesangkamore ea teko);

UP-6195F: Potoloho ea TC e phahameng le e tlase ea mocheso (kamore ea teko ea ho fetola mocheso ka potlako);

UP-6195C: Teko ea ho sisinyeha ha mocheso le mongobo (likamore tse tharo tsa tlhahlobo tse felletseng);

UP-6110: teko e potlakileng ea khatello ea maikutlo (khatello e phahameng e potlakilekamore ea teko ea botsofali);

UP-6200: tlhahlobo ea botsofali ea UV (kamore ea tlhahlobo ea botsofali ea ultraviolet);

UP-6197: teko ea ho bola ea letsoai (kamore ea teko ea setlolo sa letsoai).

Teko ea ts'ebetso le sebopeho sa sebopeho:

● Lekola sekhahla sa ho phalla ha boima ba thepa ho latela maemo a ISO 1133, boemo ba teko ke 300 ℃/1. 2 lik'hilograma;

● Lekola matla a tsitsipano le bolelele nakong ea khefu ea thepa ho latela maemo a ISO 527-1, tekanyo ea teko ke 50 mm / min;

● Leka matla a flexural le modulus ea flexural ea thepa ho latela maemo a ISO 178, tekanyo ea teko ke 2 mm / min;

● Lekola matla a matla a thepa ho latela maemo a ISO180, sebelisa mochini o etsang sampole ea notch ho lokisa notch e bopehileng joaloka "V", botebo ba notch ke 2 mm, 'me sampole e bolokoa ho -30 ℃ bakeng sa 4 h pele. teko ea tšusumetso ea mocheso o tlase;

● Leka mocheso oa mocheso oa mocheso oa thepa ho latela maemo a ISO 75-1, tekanyo ea mocheso ke 120 ℃ / min;

●Teko ea index ea bosehla (IYI):bolelele ba lehlakoreng la ente bo boholo ho feta 2 cm, botenya ke 2 mm Letlapa la 'mala oa lisekoere le behiloe tekong ea botsofali ea oksijene,' me 'mala oa poleiti ea mebala pele le ka mor'a botsofali o lekoa ka spectrophotometer. Sesebelisoa se hloka ho lekanyetsoa pele se etsoa tlhahlobo. Letlapa le leng le le leng la 'mala le lekantsoe ka makhetlo a 3 mme index e mosehla ea poleiti ea mebala e tlalehiloe;

●Tlhahlobo ea SEM:Sekhechana sa sampole se entsoeng ka ente sea seloa, khauta e fafatsoa holim'a eona, 'me morphology ea eona e bonoa tlas'a motlakase o itseng.
