YIHOO PC (Polycarbonate) cov tshuaj ntxiv
Polycarbonate (PC) yog cov polymer uas muaj cov pab pawg carbonate hauv cov saw hlau. Raws li cov qauv ntawm pawg ester, nws tuaj yeem faib ua aliphatic, ntxhiab, aliphatic - ntxhiab thiab lwm yam. Cov khoom siv kho tshuab qis ntawm aliphatic thiab aliphatic ntxhiab polycarbonate txwv lawv daim ntawv thov hauv engineering yas. Tsuas yog cov tshuaj tsw qab polycarbonate tau tsim ua khoom lag luam. Vim yog qhov tshwj xeeb ntawm cov qauv polycarbonate, PC tau dhau los ua cov plastics engineering uas muaj kev loj hlob sai tshaj plaws ntawm tsib lub tshuab yas.
PC tsis tiv taus lub teeb ci ultraviolet, muaj zog alkali, thiab khawb. Nws hloov daj nrog lub sij hawm ntev raug rau ultraviolet. Yog li ntawd, qhov xav tau rau kev hloov pauv ntxiv yog qhov tseem ceeb.
