Hauv kev siv tshuab granulation thiab cov cuab yeej siv, ntxaib - ntsia hlau underwater granulators sib txawv ntawm ntau yam granulation txoj kev vim lawv cov txheej txheem sib xyaw ua ke thiab cov txheej txheem txheej txheem.Cov kev sib txawv no tsis yog tsuas yog cuam tshuam rau hauv lawv cov qauv kev ua haujlwm thiab txheej txheem txheej txheem, tab sis kuj muaj cov ntaub ntawv siv tau, particle zoo, ib puag ncig tsim khoom, thiab yoog raws cov txheej txheem hauv kev txiav txim siab lawv txoj haujlwm.
Piv rau cov khoom siv hauv qab dej granulation配套 nrog ib zaug - ntsia hlau extrusion, qhov txawv tshaj plaws ntawm ntxaib - ntsia hlau underwater granulators nyob rau hauv lawv cov plasticizing thiab sib tov mechanisms. Lub meshing los yog tsis yog -meshing suab ntawm cov ntxaib ntsia hlau muab kev ua haujlwm shearing muaj zog thiab ntau yam sib txawv, ua tau zoo tuav siab -viscosity, siab puv, lossis ntau- cov khoom sib xyaw, thaum cov ntsia hlau ib leeg muaj qhov txwv tsis pub hloov kho kom muaj zog shearing thiab complex formulations. Qhov no txhais tau hais tias thaum cuam tshuam nrog engineering yas hloov kho, siab - kev sib xyaw xim ntawm cov masterbatches, lossis cov xwm txheej uas muaj cov khoom tsis huv hauv cov khoom siv rov ua dua, ntxaib - cov ntsia hlau underwater granulators feem ntau yuav ua tiav cov txiaj ntsig granulation nrog cov muaj pes tsawg leeg thiab ruaj khov.
Piv rau strand pelletizing, qhov sib txawv tseem ceeb ntawm ntxaib - ntsia hlau underwater pelletizers nyob rau hauv qhov txuas ntxiv ntawm cov txheej txheem txias thiab pelletizing thiab airtightness ntawm ib puag ncig. Strand pelletizing yuav tsum tau molten cov khoom yuav tsum tau extruded rau hauv ib daim hlab los ntawm ib tug tuag, txias nyob rau hauv cov huab cua, thiab ces txiav mus rau ib tug ntev ntev ntawm ib tug pelletizer. Txoj kev no muaj kev cuam tshuam rau kev hloov pauv ntawm qhov kub thiab txias thiab raug kev txom nyem los ntawm cov teeb meem xws li cov khoom siv oxidation, nto nplaum, thiab plua plav tawm. Hauv qab dej pelletizing, ntawm qhov tod tes, qhia cov dej ntws mus rau hauv cov pellets ntawm qhov hluav taws xob tuag, tso cai rau kom txias txias thiab ua kom zoo. Qhov no tiv thaiv kev kis kab mob thiab kev hloov pauv zoo los ntawm kev sib cuag ntawm huab cua, ua rau cov txheej txheem ntau lawm thiab huv si thiab ntau yam zoo li cov pellets.
Piv nrog rau cov khoom siv pelletizing qhuav, ntxaib - ntsia hlau underwater pelletizers kuj txawv nyob rau hauv lawv qhov kev cia siab rau qhov nruab nrab cua txias thiab kev tswj ntawm qhov chaw pellet. Qhuav pelletizing feem ntau ua tiav hauv huab cua los yog nyob rau hauv kev tiv thaiv roj inert, nrog rau qhov txias txias txwv los ntawm huab cua hloov hluav taws xob. Qhov no tuaj yeem ua rau saum npoo micro- tawg yooj yim hauv crystallizing yooj yim lossis siab - melting - cov ntaub ntawv taw tes. Underwater pelletizing siv dej lub siab tshwj xeeb kub muaj peev xwm thiab convective tshav kub hloov efficiency kom sai solidify lub pellet nto, ua rau cov uniform nyob rau hauv kev nyuaj siab tis thiab ruaj khov pellet zoo li. Qhov no ua rau nws tshwj xeeb tshaj yog haum rau cov khoom uas muaj kev xav tau siab rau cov tsos thiab kev ua haujlwm theem nrab flowability.
Tsis tas li ntawd, nyob rau hauv cov nqe lus ntawm cov txheej txheem kev koom ua ke, ntxaib - ntsia hlau underwater pelletizers integrate plasticizing, extrusion, pelletizing, thiab ua ntej txias rau hauv ib chav tsev, nyob ib tug kuj concentrated qhov chaw thiab ua kom yooj yim rau tag nrho cov automated tswj. Hauv qhov sib piv, qee cov kauj ruam-los ntawm- cov kauj ruam pelletizing yuav tsum tau ntxiv cov khoom siv thauj khoom thiab cua txias ntawm extrusion thiab pelletizing, ua rau cov txheej txheem nce ntxiv thiab cov ntsiab lus tsis ua haujlwm thiab kev cuam tshuam ntawm phau ntawv.
Zuag qhia tag nrho, qhov zoo sib xws ntawm ntxaib - ntsia hlau underwater pelletizers hauv plasticizing muaj peev xwm, kev ua kom txias, ua haujlwm tsis tu ncua, thiab kev yoog raws ua rau lawv zoo heev hauv kev tuav cov txheej txheem nyuaj thiab ua tau zoo - cov pellets zoo. Lawv tau dhau los ua ib qho kev xaiv tseem ceeb hauv qib siab -kawg hloov kho plastics, masterbatch, thiab engineering plastics pelletizing teb. Lawv cov yam ntxwv thev naus laus zis, uas sib txawv ntawm lawv los ntawm lwm txoj kev pelletizing, kuj tseem ua rau kev hloov pauv ntawm cov txheej txheem polymer mus rau txoj hauv kev zoo dua thiab ua tau zoo.
