Recycling thiab Regeneration
Cov txheej txheem rov ua dua thiab rov tsim dua tshiab ntawm cov hnab woven tau tsim cov txheej txheem ua tiav. Ua ntej, lawv yuav tsum tau muab cais los ntawm cov xim, raws li tus nqi ntawm cov ntaub ntawv nce tom qab kev faib tawm.
Tom ntej no los cov dej-raws li crushing thiab yaug kom tshem tawm cov stains thiab impurities. Tom qab ntawd, cov dej ntau dhau raug tshem tawm los ntawm lub centrifuge, thiab thaum kawg, cov khoom yog qhuav thiab ntim. Thaum lub sij hawm ua, lub tov khoom yog siv los muab cov ntaub ntawv sib npaug, thiab cov xim thiab cov khoom ntxiv yog ntxiv raws li xav tau.
Cov kauj ruam tseem ceeb kawg yog granulation, qhov twg cov khoom siv raw tau hloov mus rau hauv cov yas pellets los ntawm lub tshuab yas siab.
Cov pellets siv dua tshiab no muaj kev siv sib txawv nyob ntawm lawv qhov zoo. Siab - cov pellets zoo tuaj yeem siv rau kev rov ua dua, thaum nruab nrab - cov khoom zoo yog tsim rau kev txhaj tshuaj molding. Lub hauv paus tseem ceeb ntawm tag nrho cov txheej txheem rov ua dua yog ua kom cov khoom huv si, vim tias huv txaus siab - zaj duab xis siab tuaj yeem rov ua dua ncaj qha yam tsis tau ntxiv cov khoom tshiab.
Green Technology
Hauv kev siv thev naus laus zis thev naus laus zis, sib nrug los ntawm cov txheej txheem siv lub cev rov ua dua tshiab, cov thev naus laus zis tshiab tau tshwm sim tas li. Ib daim ntawv pov thawj thev naus laus zis los ntawm 2024 tau qhia txog ib txoj hauv kev los hloov cov ntaub ntawv sib txawv ntawm cov hnab ntim khoom siv rau hauv siab - cov khoom muaj nqis.
Raws li cov txheej txheem no, cov hnab yas khib nyiab ua los ntawm polyethylene thiab polypropylene tuaj yeem hloov mus rau hauv cov tshuaj tsw qab, thaum cov khoom ua los ntawm polystyrene tuaj yeem hloov mus rau hauv cov khoom resins thiab cov nplaum.
Ib txoj kev tshawb fawb hauv 2024 tau hais txog cov teeb meem kev lag luam hauv kev tsim cov hnab PP rov ua dua tshiab. Los ntawm kev ntxiv me me ntawm cov tshuaj tiv thaiv antioxidants rau cov khoom siv rov ua dua polypropylene degraded, nws muaj peev xwm tshem tawm cov dawb radicals uas tsim los ntawm cov peroxides seem, uas ua rau cov hnab woven nrog kev ruaj ntseg zoo heev thiab tiv thaiv kev laus -.
