Cov khoom siv PC yog dab tsi?
Cov khoom siv PC, lossis Polycarbonate, yog cov khoom siv polymer uas tau ntxim nyiam rau nws lub cev zoo heev thiab ntau yam kev siv. Hauv tsab xov xwm no, peb yuav ua tib zoo saib cov yam ntxwv ntawm cov khoom siv PC, lawv cov ntawv thov tseem ceeb thiab lawv qhov tseem ceeb hauv kev lag luam tshuaj.
Basic Properties ntawm cov ntaub ntawv PC
Polycarbonate (PC) paub txog nws lub zog zoo heev thiab kev cuam tshuam tsis zoo. Piv nrog rau ntau lwm yam yas, PC muaj qhov siab heev ntawm cov pob tshab thiab cov khoom siv kho qhov muag zoo, uas ua rau nws zoo tagnrho rau cov khoom xws li cov khoom siv kho qhov muag, pob tshab ntim thiab cov lus qhia. pc kuj muaj cov cua kub zoo thiab feem ntau tuaj yeem ruaj khov yam tsis muaj deformation ntawm qhov kub txog li 120 ° C. Cov khoom siv kuj muaj cov khoom siv hluav taws xob zoo. Cov khoom siv kuj muaj cov khoom siv hluav taws xob zoo, uas yog vim li cas nws kuj tau siv dav hauv kev lag luam hluav taws xob thiab hluav taws xob.
Cov cheeb tsam ntawm daim ntawv thov rau cov ntaub ntawv PC
Vim nws lub cev thiab tshuaj lom neeg zoo heev, PC tau siv ntau yam kev siv. Hauv cov neeg siv khoom siv hluav taws xob, PC yog siv los ua lub tsev txawb xov tooj, cov rooj zaum laptop, thiab lwm yam, vim tias nws yog ob qho tib si hnyav thiab muaj zog. Hauv kev tsim kho thiab kev lag luam tsheb, PC yog siv los ua lub teeb, lub tshuab cua, lub teeb pom kev zoo, thiab lwm yam khoom siv vim nws lub zog siab thiab tsis kam tiv thaiv UV rays thiab huab cua hnyav, thiab nws muaj cov ntawv thov tseem ceeb hauv cov khoom siv kho mob thiab ntim khoom noj, qhov twg nws biocompatibility thiab durability ua rau nws yog ib yam khoom uas ua tau raws li cov kev cai nruj heev.
Cov qauv tshuaj thiab ua cov khoom siv PC
Chemically, PC khoom yog synthesized los ntawm ib tug polycondensation cov tshuaj tiv thaiv ntawm bisphenol A thiab carbonate. Lub molecular saw qauv ntawm cov polymer no muab nws zoo heev txhua yam khoom thiab thermal stability. Raws li kev siv thev naus laus zis, cov khoom siv PC tuaj yeem ua los ntawm ntau txoj hauv kev xws li kev txhaj tshuaj molding, extrusion thiab tshuab moulding. Cov txheej txheem no tso cai rau cov khoom siv PC hloov mus rau qhov kev xav tau ntawm cov khoom sib txawv, thaum ua kom ntseeg tau tias lub cev ntawm cov khoom tsis raug puas tsuaj.
Environmental thiab sustainability ntawm cov ntaub ntawv PC
Txawm hais tias muaj ntau qhov zoo ntawm cov ntaub ntawv PC, kev txhawj xeeb ib puag ncig tau raug tsa. Cov khoom siv PC tsoos feem ntau yog tsim los ntawm cov khoom siv petrochemical, uas ua rau muaj kev sib tw. Nyob rau hauv xyoo tas los no, kev lag luam tshuaj lom neeg tau nquag tsim bio-based polycarbonates los txo lawv cov kev cuam tshuam ib puag ncig. Cov khoom siv PC tshiab no tsis yog tsuas yog txo cov pa roj carbon emissions, tab sis kuj tseem txhim kho cov khoom siv rov ua dua tshiab thaum tswj hwm nws cov khoom qub qub.
Cov ntsiab lus
Cov khoom siv PC yog dab tsi? Hauv luv luv, cov khoom siv PC yog cov khoom siv polycarbonate polymer uas ua haujlwm tseem ceeb hauv ntau qhov kev lag luam vim nws lub cev zoo heev thiab ntau yam ntawm daim ntawv thov kev cia siab. Txawm hais tias nyob rau hauv cov neeg siv khoom siv hluav taws xob, kev tsim kho, kev lag luam tsheb lossis cov khoom siv kho mob, daim ntawv thov ntawm cov khoom siv PC tau pom tias nws cov nqi hloov tsis tau. Nrog rau kev paub txog ib puag ncig thiab kev txhim kho thev naus laus zis, PC cov ntaub ntawv tseem tab tom txav mus rau qhov kev coj ua zoo dua qub thiab ib puag ncig tus phooj ywg thiab tseem yuav ua lub luag haujlwm tseem ceeb hauv kev lag luam tshuaj lom neeg yav tom ntej.
