Tam sim no qhov xwm txheej thiab kev loj hlob Trend ntawm daim ntawv-raws li cov ntaub ntawv sib txhuam
1 Daim ntawv-raws li luminescent khoom cua sov
Daim ntawv kuj tseem siv tau los ua kom pom lub teeb thiab ua kom sov, xws li ntawv fluorescent thiab electro-optical paper. Yog tias ib hom ntawv luminous nrog kev ua tau zoo tuaj yeem tsim tau, nws tuaj yeem hloov tau lub teeb hluav taws xob kom ua kom ci ntsa iab, txuag tau ntau yam khoom siv hluav taws xob, thiab pab txhawb tib neeg lub neej txhua hnub.
2. Cov ntaub ntawv sib txhuam cov khoom siv
Cov ntaub ntawv-raws li kev sib txhuam tau tshwm sim hauv xyoo 1950s. Nws yog ib qho ntxeem tau thiab elastic heev tshiab kev sib txhuam khoom. Nws cov khoom muaj xws li fibers, binders, kev sib txhuam kev ua tau zoo modifiers, muab tub lim, thiab lwm yam. Nws cov txheej txheem ntau lawm feem ntau siv cov ntawv zoo sib xws Nws yog tsim los ntawm cov cuab yeej siv tes ua, yog li nws yog hu ua "paper base". Daim ntawv-raws li cov ntaub ntawv sib txhuam feem ntau ua haujlwm hauv cov roj nruab nrab. Raws li hom tshiab ntawm cov khoom sib txhuam, piv nrog rau lwm cov ntaub ntawv kev sib txhuam ib txwm, cov ntaub ntawv sib txhuam cov ntaub ntawv muaj qhov sib piv me me ntawm cov khoom sib txhuam zoo li qub thiab tsis muaj zog, kev ua haujlwm qeeb, tsis tshua muaj suab nrov thiab cov nqi tiv thaiv ib puag ncig tsawg heev. Piv nrog rau cov hmoov hlau metallurgy tooj liab-raws li cov ntaub ntawv sib txhuam, uas muaj qhov sib piv loj ntawm qhov sib txhuam zoo li qub thiab dynamic kev sib txhuam coefficients thiab nrov vibrations, cov ntaub ntawv kev sib txhuam yog nrov nrog cov tuam ntxhab, yog li lawv tau siv dav. Cov ntaub ntawv sib txhuam cov ntaub ntawv yog siv los ua cov ntaub ntub dej thiab cov brakes hauv ntau lub tsheb thiab engineering machinery, tshuab cuab yeej, nkoj, mining machinery thiab lwm yam lag luam, feem ntau yog cov ntaub ntawv sib txhuam rau ntub clutches, thiab muaj ntau daim ntawv thov kev cia siab nyob rau hauv ntau yam. yam.
3. Txoj kev loj hlob ntawm cov ntaub ntawv-raws li kev sib txhuam
Nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis, cov ntaub ntawv ua haujlwm raws li cov ntaub ntawv tau dhau los ua qhov tseem ceeb ntawm cov khoom siv tshiab, uas yog qhov tseem ceeb rau lub teb chaws kev lag luam, kev loj hlob ntawm kev vam meej thiab kev tsim kho hauv lub teb chaws. Nws suav nrog bioengineering thev naus laus zis, txoj hauv kev txhim kho lub zog, nanotechnology, kev tiv thaiv ib puag ncig, thev naus laus zis thev naus laus zis, thev naus laus zis thev naus laus zis, thev naus laus zis thev naus laus zis marine engineering thiab lwm yam niaj hnub high-tech thiab lwm yam kev lag luam. Kev txhim kho thev naus laus zis ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa txoj kev loj hlob ntawm lub sijhawm.
