PC yog ib hom yas engineering uas muaj kev ua tau zoo heev hauv txhua yam. Nws muaj qhov zoo heev hauv kev tiv thaiv kev cuam tshuam, tiv thaiv cua sov, kev ruaj khov ntawm pwm thiab nplaim taws. Yog li ntawd, nws tau siv dav hauv cov khoom siv hluav taws xob, tsheb, cov khoom siv kis las thiab lwm yam teb. Txawm li cas los xij, PC molecular chains muaj ntau lub nplhaib benzene, uas ua rau nws nyuaj rau cov saw hlau molecular txav mus los, ua rau muaj qhov viscosity yaj ntawm PC. Thaum lub sijhawm ua tiav, PC molecular chains raug taw qhia. Tom qab ua tiav, qee cov saw hlau molecular uas tsis tau deoriented tag nrho hauv cov khoom feem ntau rov qab mus rau lawv lub xeev ntuj, uas yuav ua rau muaj kev ntxhov siab ntau hauv PC txhaj tshuaj molded cov khoom, ua rau muaj kev tawg thaum lub sijhawm siv khoom lossis khaws cia; tib lub sijhawm, PC yog cov khoom siv rhiab heev. Cov kev tsis txaus no txwv tsis pub nthuav dav ntxiv ntawmCov ntawv thov PC.

Yuav kom txhim kho qhov rhiab heev ntawm qhov notch thiab kev ntxhov siab ntawm PC thiab txhim kho nws cov kev ua haujlwm, cov neeg sawv cev toughening feem ntau yog siv los ua kom PC tawv. Tam sim no, cov khoom siv feem ntau siv rau kev hloov kho PC toughening hauv khw muaj xws li acrylate toughening agents (ACR), methyl methacrylate-butadiene-styrene toughening agents (MBS) thiab cov neeg sawv cev toughening uas muaj methyl methacrylate ua plhaub thiab acrylate thiab silicone ua lub hauv paus. Cov neeg sawv cev toughening no muaj kev sib raug zoo nrog PC, yog li cov neeg sawv cev toughening tuaj yeem sib npaug hauv PC.

Daim ntawv no tau xaiv 5 hom sib txawv ntawm cov neeg sawv cev tawv (M-722, M-732, M-577, MR-502 thiab S2001), thiab soj ntsuam cov teebmeem ntawm cov neeg sawv cev tawv rau PC thermal oxidation laus zog, 70 ℃ dej npau laus zog, thiab ntub cua sov (85 ℃/85%) laus zog los ntawm kev hloov pauv ntawm PC yaj ntws tus nqi, kub deformation thiab cov khoom siv kho tshuab.

Cov khoom siv tseem ceeb:

UP-6195: kev sim laus thaum tshav kub ntub (qhov kub thiab txias siab thiab qis ntub)chav kuaj cua sov);

UP-6196: kev sim cia khoom kub siab (qhov cub precision);

UP-6118: kev sim kub poob siab (txias thiab kub poob siabchav kuaj);

UP-6195F: TC lub voj voog kub siab thiab qis (chav kuaj kub hloov pauv sai);

UP-6195C: kev ntsuas kub thiab av noo (peb chav ntsuas dav dav);

UP-6110: kev sim siab ceev ceev (kev siab ceev ceev)chav kuaj laus);

UP-6200: khoom siv UV laus xeem (ultraviolet laus xeem chamber);

UP-6197: kev sim tshuaj ntsev tsuag (chav kuaj ntsev tsuag).

Kev xeem kev ua tau zoo thiab kev piav qhia txog cov qauv:

● Sim qhov ceev ntawm cov khoom yaj raws li tus qauv ISO 1133, qhov xwm txheej sim yog 300 ℃ / 1. 2 kg;

● Sim lub zog tensile thiab elongation thaum tawg ntawm cov khoom raws li tus qauv ISO 527-1, qhov kev sim ceev yog 50 hli/feeb;

● Sim lub zog flexural thiab flexural modulus ntawm cov khoom raws li tus qauv ISO 178, qhov kev xeem yog 2 hli / feeb;

● Sim lub zog cuam tshuam ntawm cov khoom siv raws li tus qauv ISO180, siv lub tshuab ua qauv piv txwv los npaj lub qhov "V" zoo li lub qhov, qhov tob ntawm lub qhov yog 2 hli, thiab cov qauv khaws cia ntawm -30 ℃ rau 4 teev ua ntej qhov kev sim cuam tshuam kub qis;

● Sim qhov kub ntawm cov khoom raws li tus qauv ISO 75-1, qhov kub thiab txias yog 120 ℃/min;

●Kev ntsuas qhov daj (IYI):Kev txhaj tshuaj molding sab ntev dua 2 cm, tuab yog 2 hli Lub phaj xim plaub fab raug rau kev kuaj xyuas kev laus ntawm cov pa oxygen thermal, thiab xim ntawm daim phaj xim ua ntej thiab tom qab kev laus raug kuaj nrog lub spectrophotometer. Cov cuab yeej yuav tsum tau calibrated ua ntej kuaj. Txhua daim phaj xim raug ntsuas 3 zaug thiab cov ntsuas daj ntawm daim phaj xim raug kaw;

●Kev tshuaj xyuas SEM:Cov qauv txhaj tshuaj pwm raug txiav ua tej daim me me, kub raug txau rau ntawm nws qhov chaw, thiab nws cov qauv saum npoo tau pom nyob rau hauv qee qhov hluav taws xob.
