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, botsitso ba boholo ba ho bopa le ho lieha ha lelakabe. Ka hona, e sebelisoa haholo lisebelisoa tsa elektroniki, likoloi, lisebelisoa tsa lipapali le masimo a mang. Leha ho le joalo, liketane tsa limolek'hule tsa PC li na le palo e kholo ea masale a benzene, e leng se etsang hore ho be thata hore liketane tsa limolek'hule li tsamaee, e leng se fellang ka viscosity e kholo ea ho qhibiliha ha PC. Nakong ea ts'ebetso ea ts'ebetso, liketane tsa limolek'hule tsa PC li sekametse. Kamora ts'ebetso, liketane tse ling tsa limolek'hule tse sa tlohang ka botlalo sehlahisoa li atisa ho khutlela boemong ba tsona ba tlhaho, e leng se tla baka khatello e kholo ea masala lihlahisoa tse entsoeng ka ente ea PC, e leng se fellang ka mapetso nakong ea ts'ebeliso kapa polokelo ea sehlahisoa; ka nako e ts'oanang, PC ke thepa e sa tsotelleng lintlha. Mefokolo ena e fokotsa katoloso e eketsehileng eaLisebelisoa tsa PC.

E le ho ntlafatsa kutloisiso ea ho sekama ha PC le ho petsoha ha khatello le ho ntlafatsa ts'ebetso ea eona ea ts'ebetso, hangata li-toughening agents li sebelisoa ho tiisa PC. Hona joale, li-additi tse sebelisoang hangata bakeng sa phetoho ea ho tiisa PC 'marakeng li kenyelletsa li-toughening agents tsa acrylate (ACR), li-toughening agents tsa methyl methacrylate-butadiene-styrene (MBS) le li-toughening agents tse entsoeng ka methyl methacrylate e le khetla le acrylate le silicone e le motheo. Li-toughening agents tsena li tsamaisana hantle le PC, kahoo li-toughening agents li ka qhalanngoa ka ho lekana ho PC.

Pampiri ena e khethile mefuta e 5 e fapaneng ea li-toughening agents (M-722, M-732, M-577, MR-502 le S2001), 'me ea hlahloba liphello tsa li-toughening agents holim'a thepa ea botsofali ba PC thermal oxidation, thepa ea botsofali ba 70 ℃ e belang metsi, le thepa ea botsofali ea mocheso o metsi (85 ℃/85%) ka liphetoho tsa sekhahla sa phallo ea PC e qhibilihang, mocheso oa phetoho ea mocheso le thepa ea mechine.

Lisebelisoa tse ka sehloohong:

UP-6195: teko ea ho tsofala ha mocheso ka metsi (e mongobo mochesong o phahameng le o tlasekamore ea teko ea mocheso);

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

UP-6118: teko ea ho tšoha ha mocheso (ho tšoha ho batang le ho chesang)kamore ea liteko);

UP-6195F: Potoloho ea mocheso o phahameng le o tlase oa TC (kamore ea teko ea phetoho e potlakileng ea mocheso);

UP-6195C: teko ea ho thothomela ha mocheso le mongobo (likamore tse tharo tse felletseng tsa liteko);

UP-6110: teko ea khatello e potlakileng haholo (khatello e phahameng e potlakisitsoe)kamore ea teko ea botsofali);

UP-6200: teko ea botsofali ba UV ea thepa (kamore ea teko ea botsofali ea ultraviolet);

UP-6197: teko ea ho bola ha spray ea letsoai (kamore ea teko ea spray ea letsoai).

Teko ea ts'ebetso le tlhaloso ea sebopeho:

● Leka sekhahla sa phallo ea boima ba ho qhibiliha ha thepa ho latela maemo a ISO 1133, boemo ba teko ke 300 ℃/1. 2 kg;

● Leka matla a ho thapolla le ho lelefatsa ha thepa e robeha ho latela maemo a ISO 527-1, sekgahla sa teko ke 50 mm/min;

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

● Leka matla a ho tshwarwa ha thepa ho ya ka maemo a ISO180, sebedisa mochini o etsang sampole ya ho tshwarwa ho lokisa ho tshwarwa ha sebopeho sa "V", botebo ba ho tshwarwa ha thepa ke 2 mm, mme sampole e bolokwa ho -30 ℃ dihora tse 4 pele ho teko ya ho tshwarwa ha mocheso o tlase;

● Leka mocheso oa ho feto-fetoha ha mocheso oa thepa ho latela maemo a ISO 75-1, sekhahla sa ho futhumatsa ke 120 ℃/min;

●Teko ea index ea bosehla (IYI):Bolelele ba lehlakore la ho bopa ka ente bo feta 2 cm, botenya ke 2 mm Poleiti ea 'mala o sekoere e etsoa teko ea botsofali ba oksijene ea mocheso, 'me 'mala oa poleiti ea 'mala pele le ka mor'a botsofali o lekoa ka spectrophotometer. Sesebelisoa se hloka ho lekanngoa pele se lekoa. Poleiti e 'ngoe le e 'ngoe ea 'mala e lekanngoa ka makhetlo a 3 'me index e mosehla ea poleiti ea 'mala e tlalehiloe;

●Tlhahlobo ea SEM:Sekotwana sa sampole se entsweng ka ente se sehiloe, kgauta e fafatswa hodima bokahodimo ba sona, mme sebopeho sa bokahodimo ba sona se bonwa tlasa motlakase o itseng.
