Polycarbonate yog dab tsi?
Polycarbonate (PC) yog cov khoom siv polymer dav siv hauv kev lag luam tshuaj lom neeg thiab yog ib qho khoom siv uas nyiam tshaj plaws hauv ntau lub cev thiab tshuaj siv tshuaj lom neeg. Hauv tsab xov xwm no, peb yuav txheeb xyuas kom meej cov muaj pes tsawg leeg thiab cov khoom ntawm polycarbonate thiab nws cov kev siv ntau yam.
1. Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov qauv ntawm Polycarbonate
Polycarbonate yog chav kawm ntawm Bisphenol A (BPA) thiab carbonate pawg los ntawm cov kev coj ua txawv txav ntawm Polycondensies tsim los ntawm cov xas linear. Nws cov molecular charmoons muaj ntau ntawm cov pab pawg carbonate (-o-co-o), tus qauv no muab cov khoom siv polycarbon ua tsis tau zoo, transparency thiab kev cuam tshuam tsis kam. Lub tshuaj lom neeg muaj peev xwm ntawm polycarbonate ua rau nws tswj hwm nws cov khoom tsis hloov pauv hauv ib puag ncig heev, ua rau nws muaj cov khoom siv ruaj khov.
2. Cov yam ntxwv tseem ceeb ntawm Polycarbonate
Polycarbonate cov ntaub ntawv yog paub rau nws cov khoom siv lub cev zoo dua. Nws muaj cov kev cuam tshuam ntau heev, 250 lub sij hawm uas ntawm cov iav zoo tib yam, uas yuav tsum muaj lub zog siab thiab cuam tshuam tsis kam. Polycarbonate muaj cov kub ua hluav taws xob tau zoo heev, seem nyob ntawm -40 ° C rau 120 ° C, uas tso cai rau nws ua tau zoo nyob rau hauv qhov chaw kub-ib puag ncig. Polycarbonate kuj tseem muaj cov zoo hloov kho kho qhov muag, kis ntau dua 90 feem pua ​​ntawm kev tsim kho lub teeb thiab pob tshab.
3. Daim ntawv thov cheeb tsam ntawm Polycarbonate
Vim yog cov khoom tshwj xeeb ntawm cov ntaub ntawv Polycarbonate, nws tau siv dav hauv ntau yam kev lag luam. Hauv kev tsim kho kev tsim kho, Polycarbonate siv tau siv cov vaj huam sib luag cov vov tsev, cov ntaub ntawv vov tsev thiab cov khoom siv acoustic. Nws cov kev cuam tshuam zoo heev thiab pob tshab ua nws tsis tseem ceeb hauv cov chaw no. Hauv cov khoom hluav taws xob thiab hluav taws xob, polycarbonate siv los ua cov khoom siv hluav taws xob, cov khoom siv hauv tsev thiab roj teeb Rwb thaiv tsev thiab cov hluav taws xob rwb thaiv tsev. Polycarbonate tseem dav nyob hauv kev lag luam hauv tsheb, feem ntau yog rau cov teeb meem, ntsuas panels thiab lub qhov rais. Tseem ceeb tshaj, Polycarbonate tseem dav nyob hauv cov khoom siv kho mob, xws li cov cuab yeej siv dag zog, thiab kev thov khi ua tsaug thiab biocompatibility ntawm polycarbonate cov ntaub ntawv.
4. Ib puag ncig tus phooj ywg thiab rov ua dua Polycarbonate
Txawm hais tias Polycarbonate yog cov khoom siv ruaj khov thiab ntau yam, Bisphenol A (BPA) koom nrog qee qhov kev sib cav ib puag ncig. Raws li thev naus laus zis kev nce qib, ntau dua thiab ntau dua ib puag ncig cov khoom lag luam Polycarbonate tau tsim uas txo qhov cuam tshuam ntawm ib puag ncig. Kev ua dua tshiab ntawm Polycarbonate kuj tseem muaj kev mloog zoo, thiab los ntawm kev tsim cov txheej txheem, khib nyiab polycaration, hloov zuj zus los hloov cov khoom lag luam tshiab kom txo cov pov tseg.
Tag
Polycarbonate yog dab tsi? Nws yog cov khoom siv polymer nrog ntau yam khoom siv zoo dua, thiab yog siv dav dav, kho tsheb, kub tsis kam, pob tshab thiab tshuaj lom neeg ruaj khov. Nrog rau kev tiv thaiv ntxiv ntawm kev tiv thaiv ib puag ncig, kev rov ua dua tshiab ntawm Polycarbonate tau nce zuj zus. Polycarbonate yog cov khoom siv uas yog ob qho tib si kev ua tau zoo thiab muaj peev xwm ua kom muaj kev txhim kho kom ruaj khov.
