Dab tsi yog cov khoom siv rau?
Cov khoom siv PC, lossis polycarbonate, yog cov khoom siv polymer uas tau nyiam cov khoom rau nws cov khoom siv lub cev zoo nkauj thiab ntau cov kev siv. Hauv tsab xov xwm no, peb yuav ua tib zoo saib ntawm cov khoom tseem ceeb ntawm cov ntaub ntawv PC, lawv cov ntawv thov tseem ceeb thiab lawv qhov tseem ceeb hauv kev lag luam tshuaj.
Cov Khoom Yooj Yim Ntawm Cov Ntaub Ntawv Pc
Polycarbonate (PC) paub txog nws lub zog zoo thiab cuam tshuam tsis kam. Piv rau ntau lwm cov plastics, PC muaj cov khoom siv kho tshiab zoo nkauj thiab cov khoom siv kho tau zoo xws li cov khoom siv kho qhov muag, pob tshab ntim thiab cov lus qhia. PC kuj muaj cov cua sov ua kom zoo thiab feem ntau yog muaj peev xwm nyob ruaj khov tsis muaj deformation ntawm qhov kub txog li 120 ° C. Cov khoom siv kuj muaj hluav taws xob rwb thaiv tsev hluav taws xob. Cov khoom siv kuj muaj hluav taws xob insulation zog, uas yog vim li cas nws tseem muaj hluav taws xob thiab kev lag luam hluav taws xob.
Thaj chaw ntawm daim ntawv thov rau cov ntaub ntawv PC
Vim nws cov khoom siv lub cev thiab tshuaj lom neeg zoo, pc siv tau ntau yam ntawm cov ntawv thov. Nyob rau hauv cov neeg siv khoom siv khoom siv hluav taws xob, PC tau siv los ua cov neeg hauv xov tooj ntawm tes, laptop neeg, thiab lwm yam. Hauv kev tsim kho tsheb, PC siv tau los ua lub teeb, thiab muaj huab cua ua haujlwm thiab muaj cov cuab yeej tseem ceeb rau cov khoom noj thiab cov khoom noj khoom haus ntim khoom, qhov twg nws Biocompatibility thiab retability ua nws cov khoom uas ua tau raws li kev ua kom nruj kev nyab xeeb.
Cov qauv tshuaj thiab kev ua cov ntaub ntawv PC
Chemically, cov khoom siv pc yog synthesized los ntawm kev coj ua ntawm polycondens ntawm bisphenol a thiab carbonate. Cov molecular saw qauv ntawm cov polymer no muab nws cov khoom siv kho tshuab thiab hluav taws xob ruaj khov. Hais txog thev naus laus zis, cov khoom siv PC tuaj yeem yog cov pwm los ntawm ntau cov hau kev xws li kev txhaj tshuaj molding, extrusion thiab tshuab moulding. Cov txheej txheem no tso cai rau cov khoom siv rau cov qauv tsim nyog ntawm cov qauv kev xav tau ntawm cov khoom sib txawv, thaum ua kom cov khoom siv lub cev ntawm cov khoom tsis raug puas.
Ib puag ncig thiab kev ua kom zoo ntawm cov ntaub ntawv PC
Dua li ntawm cov zoo ntawm cov ntaub ntawv PC, kev txhawj xeeb ib puag ncig tau raug tsa. Cov ntaub ntawv siv PC tsoos pvc feem ntau yog tsim los ntawm cov roj av raw, uas ua rau muaj kev sib tw muaj kev sib tw. Nyob rau hauv xyoo tas los, kev lag luam tshuaj tau nquag tsim kev txhim kho xyoob ntoo polycarbonates los txo lawv cov kev cuam tshuam ib puag ncig. Cov cuab yeej siv PC tshiab tsis tsuas yog txo cov pa roj carbon monissions, tab sis kuj ua rau rov ua dua tshiab ntawm cov khoom siv thaum lub cev qub lub cev.
Lub ntsiab
Dab tsi yog cov khoom siv rau? Hauv ntej, cov khoom siv rau PC yog cov khoom siv polymerbon uas nyob hauv ntau txoj haujlwm tseem ceeb hauv ntau yam lag luam vim tias nws cov ntaub ntawv zoo tshaj plaws thiab cov khoom siv ntau yam. Txawm hais tias nyob hauv cov khoom siv hluav taws xob, kev tsim kho, kev lag luam tsheb lossis cov khoom siv kho mob, daim ntawv thov ntawm PC cov khoom tau ua kom pom nws tus nqi. Nrog rau kev nce qib kev paub thiab thev naus laus zis, cov ntaub ntawv PC kuj tau txav mus rau hauv txoj haujlwm tseem ceeb dua hauv kev lag luam hauv lub neej tom ntej.
