Cov yam ntxwv ntawm Polycarbonate

Polycarbonate, ntawm qhov tod tes, yog pob tshab, amorphous thermoplastic. Nws yog qhov paub zoo rau nws qhov tshwj xeeb cuam tshuam tsis kam, dhau ntawm PMMA thiab txawm tias qee cov hlau. Polycarbonate kuj tseem muaj zog heev, nrog lub peev xwm tiv taus qhov kub thiab txias yam tsis muaj deformation tseem ceeb. Tsis tas li ntawd, nws muaj cov khoom siv hluav taws xob zoo heev, ua rau nws tsim nyog rau kev siv hluav taws xob thiab hluav taws xob.

Kev siv ntawm polycarbonate

Polycarbonate cov yam ntxwv tshwj xeeb ua rau nws siv dav hauv ntau lub lag luam, suav nrog:

1. Khoom siv kev nyab xeeb: Polycarbonate qhov tshwj xeeb cuam tshuam ua rau nws cov khoom xaiv rau cov khoom siv kev nyab xeeb xws li iav mos txwv, cov ntaub thaiv kev kub ntxhov, thiab cov kaus mom hlau. Nws lub teeb hnyav ntxiv ntxiv rau kev ua haujlwm ntawm cov ntawv thov no.

2. Tsev cog khoom: Polycarbonate muaj peev xwm xa tawm lub teeb thaum muab rwb thaiv tsev ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim tsev cog khoom. Nws tso cai rau lub hnub ci nkag mus rau hauv thiab ntxiab cua sov, tsim kom muaj qhov chaw zoo rau cov nroj tsuag loj hlob.

3. Hluav taws xob Cheebtsam: Vim nws cov khoom siv hluav taws xob zoo heev, polycarbonate tau siv dav hauv kev tsim cov khoom siv hluav taws xob, hloov hluav taws xob, thiab cov hluav taws xob hluav taws xob.

4. Automotive Cheebtsam: Polycarbonate's cuam tshuam tsis kam thiab ua haujlwm ntev ua rau nws yog cov khoom tsim nyog rau kev siv tsheb xws li cua tshuab, hnub ci, thiab cov khoom siv sab nrauv.

5. Khoom siv kho mob: Polycarbonate yog siv rau hauv kev tsim khoom siv kho mob, xws li incubators, sterilization trays, thiab ntshav oxygenators. Nws biocompatibility thiab muaj peev xwm tiv taus autoclave sterilization ua rau nws haum rau cov hom phiaj no.

Qhov zoo ntawm PMMA **
