Yuav kom txhawb nqa kev tswj hwm tag nrho ntawm cov yas ua qias tuaj thiab ua kom nrawm dua kev txhim kho ntawm "hloov yas nrog xyoob", Lub Chaw Haujlwm Saib Xyuas Kev Txhim Kho thiab Kev Hloov Kho Hauv Tebchaws thiab lwm lub chaw haujlwm tau tshaj tawm "Txoj Kev Npaj Ua Haujlwm Peb-Xyoo rau Kev Ua Kom nrawm dua kev txhim kho ntawm "Hloov Yas nrog Xyoob". Thaum Lub Kaum Ib Hlis 7, Lub Chaw Haujlwm Dav Dav ntawm Pawg Sab Laj Hauv Xeev tau tshaj tawm "Xyoob rau Yas", thov kom pib tsim kom muaj "Xyoob rau Yas" kev lag luam los ntawm xyoo 2025 los txhim kho qhov zoo, hom khoom, qhov ntsuas kev lag luam, thiab cov txiaj ntsig dav dav ntawm cov khoom "Xyoob rau Yas". Cov khoom tsim tawm ntawm "Plastics", uas yog lub hom phiaj ntawm kev nqis tes ua, tau nce ntxiv ntau heev, thiab feem ntawm kev ua lag luam ntawm cov khoom tseem ceeb tau nce ntxiv ntau heev.
Kev sib xyaw cov khoom siv los ua kom siv tau zoo tshaj plaws
Xyoob tau tshwm sim hauv ntiaj teb kwv yees li 30 lab xyoo dhau los thiab yog ib qho ntawm cov nroj tsuag loj hlob sai tshaj plaws hauv ntiaj teb. Xyoob muaj ntau cov xyoob fiber, thiab cov ntaub ntawv thiab cov khoom siv ua tiav rau hauv nws muaj cov khoom siv kho tshuab muaj zog heev. Yog tias ua tiav rau hauv cov khoom siv ua haujlwm, nws cov teb siv tuaj yeem nthuav dav heev. Piv nrog cov yas ib txwm muaj thiab lwm yam ntaub ntawv, cov ntaub ntawv bio-raws li xws li xyoob thiab ntoo muaj cov txiaj ntsig zoo dua rau kev tiv thaiv ib puag ncig thiab tuaj yeem hloov cov ntaub ntawv ib txwm muaj xws li yas, hlau, thiab cement rau qhov loj tshaj plaws. Tam sim no lawv tau dhau los ua cov lag luam tshiab uas ua rau kev txhim kho kev lag luam thiab kev tsim kho tshiab. Tau kawg, nws nyuaj rau kom siv xyoob ntau tshaj plaws los ntawm cov kev siv ib zaug xwb. Composites daws qhov teeb meem no. Cov thev naus laus zis xyoob winding tsim los ntawm kuv lub teb chaws sib xyaw cov xyoob hloov kho nrog cov resin, ua kom siv tag nrho cov tawv ntawm xyoob fiber thiab lub zog siab axial ntawm xyoob kom tau txais cov ntaub ntawv sib xyaw annular tsis muaj qhov tsis zoo. Qhov zoo tshaj plaws ntawm cov thev naus laus zis no yog tias nws tuaj yeem ua ke xyoob nrog lwm yam ntaub ntawv, yog li cov ntaub ntawv tshiab tsis tsuas yog muaj qhov tawv, lub zog thiab kev tiv thaiv ib puag ncig ntawm xyoob, tab sis kuj suav nrog lub zog siab, kev tiv thaiv corrosion thiab lwm yam zoo ntawm lwm yam ntaub ntawv.
