Polyethylene (PE), uas yog ib qho ntawm lub ntiaj teb loj tshaj plaws - tsim thiab siv cov thermoplastic resins feem ntau, nyob hauv txoj haujlwm tseem ceeb hauv kev ntim khoom, cov khoom siv hauv tsev, kev ua liaj ua teb, cov khoom siv niaj hnub, thiab cov khoom lag luam. Txawm li cas los xij, PE ntshiab muaj qee qhov kev txwv ntawm lub zog, tiv thaiv tshav kub, tiv thaiv huab cua, thiab kev ua haujlwm, ua rau nws nyuaj ua kom tau raws li cov kev xav tau ntawm kev tsim khoom niaj hnub rau lub teeb yuag, siab -kev ua tau zoo, ntau yam, thiab cov ntaub ntawv zoo ib puag ncig. Nrog rau kev txhim kho cov kev lag luam hauv qab thiab kev sib txawv ntawm cov neeg siv khoom xav tau, PE hloov kho thev naus laus zis tau tsim kho sai, dhau los ua txoj hauv kev tseem ceeb los txhim kho nws cov nqi ntxiv thiab nthuav dav nws daim ntawv thov ciam teb. Tawm tsam qhov keeb kwm yav dhau los no, PE tau hloov kho peb -screw granulator, raws li cov khoom siv tseem ceeb rau kev ua tau zoo thiab kev hloov kho zoo ib yam, yog qhov tseem ceeb ntawm kev lag luam thiab qhov tseem ceeb ntawm cov tswv yim.
Los ntawm kev xav txog keeb kwm yav dhau los ntawm kev lag luam, kev lag luam yas thoob ntiaj teb yog nyob rau theem tseem ceeb ntawm kev hloov pauv, hloov los ntawm kev nthuav dav mus rau kev txhim kho kom zoo, thiab los ntawm - cov khoom siv rau cov khoom siv tshwj xeeb thiab ua haujlwm. Ntawm qhov tod tes, kev lag luam ntim cov kev thov rau kev thaiv, cua sov- tiv taus, thiab biodegradable zog yog tsav cov kev hloov pauv ntawm PE nrog bio- cov khoom siv thiab nano- additives. Ntawm qhov tod tes, lub tsheb, khoom siv hauv tsev, thiab kev tsim kho kev lag luam tau teeb tsa cov qauv siab dua rau lub teeb yuag, siab -lub zog, cuam tshuam- tiv taus, thiab nplaim taws-cov khoom siv hluav taws xob, ua rau cov qauv hloov pauv mus rau qib siab - muab tub lim, ntau- cov khoom siv, thiab cov tshuab ua haujlwm nyuaj. Cov qauv no ua rau muaj kev sib tw rau ib txwm ib txwm -ntsia hlau lossis ntxaib- cov khoom siv ntsia hlau granulation nyob rau hauv cov nqe lus ntawm dispersion uniformity, thermal tswj precision, thiab txheej txheem kam rau ua. Peb-screw granulators, nrog rau lawv qhov zoo ntawm ntau- ntsia hlau synergy thiab adjustable flow field, tuaj yeem daws qhov kev sib tw ntawm siab -viscosity, siab{18}}filler, thiab qis-cov khoom sib xws, thiab yog li maj mam tau txais kev lees paub thiab kev txhawb nqa.
Qhov tseem ceeb ntawm PE hloov peb -screw granulator feem ntau nyob hauv nws cov kev ua tau zoo dua qub. Nws qhov tshwj xeeb peb - ntsia hlau meshing thiab ntws channel layout nthuav tawm cov shearing thiab sib tov ntau yam ntawm cov ntaub ntawv nyob rau hauv lub chim, zoo tshem tawm cov tuag zones, txo qhov kev pheej hmoo ntawm thermal degradation, thiab ho txhim kho qhov dispersion thiab interfacial bonding ntawm fillers, additives, thiab PE matrix, yog li ua kom muaj kev ruaj ntseg thiab ruaj khov. Thib ob, cov cuab yeej no khav theeb zoo hauv cov txheej txheem hloov kho. Los ntawm kev sib xyaw ua ke ntawm cov ntsia hlau sib txuas thiab hloov pauv hloov pauv, nws tuaj yeem hloov kho cov qib PE nrog cov ntsuas sib txawv, qhov ntom ntom, thiab cov qauv tsim, ua kom luv cov khoom lag luam tshiab thiab kev hloov pauv ntau lawm, thiab txhim kho kev lag luam kev lag luam yooj yooj yim thiab kev lag luam kev sib tw.
Nyob rau theem kev lag luam, daim ntawv thov dav dav ntawm PE tau hloov kho peb -screw granulator pab tsav kev txhim kho cov ntaub ntawv hloov kho mus rau qhov siab- kawg thiab cov ntawv thov ua haujlwm, ua tau raws li cov kev xav tau ntawm cov kev lag luam tawm tswv yim xws li ntim ntsuab, lub zog tshiab, thiab lub zog- cov vaj tsev muaj txiaj ntsig, thiab ua kom cov khoom sib koom ua ke ntawm cov khoom lag luam nce qib, thiab cov khoom siv sib xyaw ua ke. Nyob rau tib lub sijhawm, nws cov kev sib xyaw ua tau zoo thiab kev tswj xyuas qhov kub thiab txias tuaj yeem txo cov khoom siv hluav taws xob thiab cov khoom siv raw khoom poob rau qee qhov, ua raws li txoj cai kev txuag hluav taws xob, txo qis emissions, thiab kev txhim kho kom ruaj khov, thiab txhim kho kev siv cov peev txheej efficiency thiab ib puag ncig tus phooj ywg ntawm tag nrho cov kev lag luam plastics.
Hauv cov ntsiab lus, PE hloov kho peb -screw granulator tsis yog tsuas yog ib qho tseem ceeb rau kev paub txog cov txheej txheem hloov kho PE tab sis kuj yog qhov tseem ceeb txuas txuas cov khoom siv tshiab thiab xaus- siv daim ntawv thov. Nws txoj kev loj hlob thiab kev muaj npe nrov muaj qhov tseem ceeb tshaj plaws rau kev txhim kho cov kev sib tw tseem ceeb ntawm kuv lub teb chaws kev hloov kho plastics kev lag luam, txhawb cov khoom lag luam optimization, thiab kev hloov pauv ntsuab.
