1. Pib
Polycarbonate (abbriatiat Nws yog cov pob tshab tsis muaj xim lossis daj me ntsis tawv tawv tawv. Nws qhov hloov tau yog thib ob rau PMMA thiab PS. Nws qhov kev hloov pauv hluav taws xob tuaj yeem ncav cuag 89%. Nws tsis muaj ntxhiab, tsis muaj tshuaj lom, thiab muaj cov xim zoo. Nws tuaj yeem ua rau hauv ntau cov khoom muaj xim.

Cov cawv ntawm cov pab pawg ntawm lub ntsiab saw ntawm pc
1. Phenylene pab pawg: ib pawg loj heev uas txwv txoj kev sib hloov sab hauv ntawm cov molecular seeb ntu;
2. Cov pab pawg Eserer: ib pawg qib polar uas muab ib pawg loj sib xyaw ua ke los khi cov hlua roj molecular rau txhua lwm yam thiab tsis muaj zog ntawm cov kab molecular;
Phenykas thiab ester pawg txiav txim siab tias lub PC yog molecule loj uas muaj zog rigidity. Yog li ntawd, lub iav hloov cua kub thiab yaj kub ntawm cov polymer yog qhov siab tsis yooj yim, muaj zog ua haujlwm tsis yooj yim, thiab zoo daws cov dej tsis kam thiab dej tsis kam.
Kev sib faib
Raws li cov pab pawg sib txawv, Polycarbonate tuaj yeem faib ua ntau hom, xws li aliphaatic, alcicyclic, muaj ntxhiab thiab aliphatic-aromatic. Yog tsis muaj lwm yam kev teev tseg, Polycarbonate feem ntau yog hais txog Bisphenol lub polycarbonate thiab nws hloov kho ntau yam.
Raws li kev siv, Polycarbonate tuaj yeem faib ua cov PC, UV-resistant thiab huab cua-qib PC, thiab PC siv tshuaj-tsis haum tshuaj.
