PC yog hom yas engineering nrog kev ua tau zoo hauv txhua yam. Nws muaj cov txiaj ntsig zoo hauv kev cuam tshuam, kub tsis kam, molding dimensional stability thiab nplaim retardancy. Yog li ntawd, nws yog dav siv nyob rau hauv cov khoom siv hluav taws xob, tsheb, cov khoom ua si thiab lwm yam. Txawm li cas los xij, PC molecular chains muaj ntau cov benzene rings, uas ua rau nws nyuaj rau cov saw hlau molecular txav, uas ua rau muaj cov viscosity loj ntawm PC. Thaum lub sijhawm ua cov txheej txheem, PC molecular chains yog taw qhia. Tom qab ua tiav, qee qhov ntawm cov saw hlau molecular uas tsis yog deoriented tag nrho hauv cov khoom yuav rov qab mus rau lawv lub xeev ntuj, uas yuav ua rau muaj kev ntxhov siab ntau ntxiv hauv PC txhaj tshuaj molded cov khoom, uas ua rau tawg thaum siv khoom lossis cia khoom; Tib lub sijhawm, PC yog cov khoom siv tsis zoo. Cov shortcomings txwv qhov nthuav ntxiv ntawmKev siv PC.

Txhawm rau txhim kho qhov rhiab heev thiab kev ntxhov siab tawg ntawm PC thiab txhim kho nws cov kev ua tau zoo, cov neeg ua haujlwm toughening feem ntau yog siv los ua kom tawv PC. Tam sim no, cov additives feem ntau siv rau PC toughening hloov kho nyob rau hauv kev ua lag luam muaj xws li acrylate toughening agents (ACR), methyl methacrylate-butadiene-styrene toughening agents (MBS) thiab toughening agents muaj li ntawm methyl methacrylate li plhaub thiab acrylate thiab silicone li core. Cov neeg ua haujlwm toughening no muaj kev sib raug zoo nrog PC, yog li cov neeg ua haujlwm toughening tuaj yeem sib npaug sib npaug hauv PC.

Daim ntawv no tau xaiv 5 lub npe sib txawv ntawm cov tshuaj toughening (M-722, M-732, M-577, MR-502 thiab S2001), thiab soj ntsuam cov teebmeem ntawm toughening agents ntawm PC thermal oxidation aging zog, 70 ℃ dej boiling laus zog, thiab ntub dej kub (85 ℃ / 85%) aging zog los ntawm kev hloov hauv PC yaj ntws tus nqi, kub deformation kub thiab txhua yam khoom.

Main equipments:

UP-6195: ntub dej kub aging test (siab thiab qis kub ntubcua sov chav kuaj);

UP-6196: ntsuas kub cia (qhov cub qhov tseeb);

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

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

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

UP-6110: Kev ntsuas siab ceev ceev (siab ceev ceevaging test chamber);

UP-6200: cov khoom siv UV aging test (ultraviolet aging test chamber);

UP-6197: ntsev tsuag tshuaj tiv thaiv corrosion (salt spray test chamber).

Kev ntsuam xyuas kev ua tau zoo thiab cov yam ntxwv ntawm cov qauv:

● Kuaj cov yaj huab hwm coj tus nqi ntawm cov khoom raws li ISO 1133 tus qauv, qhov kev sim ntsuas yog 300 ℃ / 1. 2 kg;

● Ntsuas lub zog tensile thiab elongation ntawm kev tawg ntawm cov khoom raws li ISO 527-1 tus qauv, qhov ntsuas tus nqi yog 50 mm / min;

● Ntsuam xyuas lub zog flexural thiab flexural modulus ntawm cov khoom raws li ISO 178 tus qauv, qhov ntsuas tus nqi yog 2 hli / min;

● Ntsuam xyuas qhov cuam tshuam ntawm lub zog ntawm cov khoom raws li ISO180 tus qauv, siv cov qauv coj los ua lub tshuab los npaj "V"-zoo li tus ntiv taw, qhov tob tob yog 2 hli, thiab cov qauv khaws cia ntawm -30 ℃ rau 4 h ua ntej qhov ntsuas kub ntawm qhov ntsuas kub tsawg;

● Ntsuas qhov kub ntawm qhov deformation ntawm cov khoom raws li ISO 75-1 tus qauv, tus nqi cua sov yog 120 ℃ / min;

●Yellowness index (IYI) test:Kev txhaj tshuaj molding sab ntev yog ntau dua 2 cm, thickness yog 2 hli Lub square xim phaj yog raug rau thermal oxygen aging test, thiab cov xim ntawm cov xim phaj ua ntej thiab tom qab kev laus yog kuaj nrog ib tug spectrophotometer. Lub ntsuas yuav tsum tau calibrated ua ntej kuaj. Txhua lub phaj xim yog ntsuas 3 zaug thiab qhov ntsuas daj ntawm cov xim phaj raug kaw;

●SEM Analysis:Kev txhaj tshuaj molded qauv sawb yog hlais, kub yog txau rau ntawm nws qhov chaw, thiab nws qhov chaw morphology tau pom nyob rau hauv qee qhov hluav taws xob.
