Pelletising, txheej txheem tseem ceeb hauv kev tsim cov khoom yas, tsom rau kev rov ua dua thiab tsim cov yas pellets, uas yog cov khoom siv raw rau ntau yam kev siv xws li kev tsim cov yeeb yaj kiab, txhaj tshuaj molding thiab extrusion. Muaj ntau cov pelletising technologies muaj, uas cov zaj duab xis bi-theem pelletising ntau lawm kab sawv tawm raws li tau ntau nruab nrog cov efficiency thiab zoo los tsim cov pellets zoo los ntawm cov ntaub ntawv pov tseg yas.
Hloov cov ntaub ntawv raw xws li cov yas pov tseg rau hauv me me, cov pellets tsis zoo yog cov txheej txheem ntawm pelletising, thiab tag nrho cov txheej txheem ntawm pelletising suav nrog, pub, melting, extruding, txias thiab txiav los tsim cov pellets uas tau yooj yim tuav, thauj thiab ua tiav hauv cov theem tom ntej. ntawm kev tsim khoom.
Pelletising technologiestuaj yeem muab faib ua ob pawg: ib-theem pelletising thiab ob-theem pelletising. Ib-theem pelletising siv ib qho extruder yaj cov khoom thiab ua cov pellets, whereas ob-theem pelletising siv ob extruders, tso cai rau kom meej meej tswj ntawm melting thiab txias txheej txheem, ua rau cov pellets zoo dua.
Zaj duab xis ob-theempelletizing kabyog tsim los ua cov yeeb yaj kiab yas xws li polyethylene (PE) thiab polypropylene (PP). Cov thev naus laus zis yog qhov tshwj xeeb rau kev rov ua dua tshiab ntawm cov neeg siv khoom yas, uas feem ntau nyuaj rau cov txheej txheem vim lawv qhov ntom nti thiab nyiam ua ke.
Kev pub noj thiab ua ntej yuav tsum ua ntej pub rau lub cev nrog cov yas zaj duab xis seem, uas feem ntau torn rau hauv me me los pab tuav thiab ua. Kev kho ua ntej kuj tseem suav nrog kev ziab cov khoom kom tshem tawm cov dej noo, uas yog qhov tseem ceeb rau kev ua kom zoo tshaj plaws thiab pelletizing.
Nyob rau hauv thawj theem, shredded yas zaj duab xis yog pub rau hauv thawj extruder, uas yog nruab nrog ib tug ntsia hlau uas melts cov khoom los ntawm mechanical shearing thiab cua sov. Tom qab ntawd cov yas melted yog yuam los ntawm ib qho screen kom tshem tawm impurities thiab xyuas kom meej ib yam li melting.
Ntxig, thov xav txog peb lub tuam txhab cov khoom no,LQ250-300PE Zaj duab xis Ob-theem Pelletizing Kab
Los ntawm thawj extruder, cov khoom molten dhau mus rau hauv lub extruder thib ob, ib theem uas tso cai rau ntxiv homogenisation thiab degassing, uas yog ib qho tseem ceeb kom tshem tawm cov volatiles residual los yog noo noo uas yuav cuam tshuam qhov zoo ntawm cov pellet zaum kawg. Qhov thib ob extruder feem ntau yog khiav ntawm qhov qis dua, uas pab tswj cov khoom ntawm cov yas.
Tom qab theem ob ntawm extrusion, pelletizer yog siv los txiav cov yas molten rau hauv pellets, uas tuaj yeem ua kom txias hauv qab dej lossis los ntawm huab cua, nyob ntawm qhov tshwj xeeb ntawm cov txheej txheem tsim khoom. Cov pellets ua tau zoo sib xws hauv qhov loj thiab cov duab thiab tsim nyog rau ntau yam kev siv.
Thaum cov pellets yog molded, lawv yuav tsum tau txias thiab solidified, thiab ces qhuav kom tshem tawm cov dej ntau dhau. Kev ua kom txias thiab ziab kom zoo yog qhov tseem ceeb los xyuas kom meej tias covpelletstswj lawv txoj kev ncaj ncees thiab tsis txhob clump.
Thaum kawg, cov pellets tau ntim rau kev khaws cia lossis thauj, txheej txheem tsim los txo cov kab mob thiab xyuas kom meej tias cov pellets nyob rau hauv qhov zoo tshaj plaws ua ntej siv.
Hauv qab no yog qee qhov piv txwv ntawm qhov zoo ntawm ob-theem pelletising kab rau cov yeeb yaj kiab:
- Ntau dua pellet zoo:txheej txheem ob-theem tso cai rau kev tswj kom zoo dua ntawm cov txheej txheem melting thiab txias, ua rau cov pellets zoo dua nrog kev txhim kho lub cev.
- Kev tshem tawm cov kab mob ntau dua:Cov txheej txheem ob-theem extrusion zoo tshem tawm cov kab mob thiab cov volatiles, uas ua rau kom huv, zoo ib yam pellets.
- Versatility:Lub tshuab tuaj yeem ua tiav ntau yam ntawm cov yeeb yaj kiab yas, ua rau nws tsim nyog rau ntau yam kev siv rov ua dua tshiab.
- Zog efficiency:Cov tshuab bipolar feem ntau yog tsim los siv lub zog tsawg dua li ib-theem systems, ua rau lawv muaj kev xaiv zoo dua.
- Txo downtime:qhov tsim tau zoo ntawm cov yeeb yaj kiab bi-theem pelletising kab txo qis qis qis thaum lub sijhawm tsim khoom, ua rau muaj kev tsim tawm thiab tsim khoom.
Pelletising technology plays lub luag haujlwm tseem ceeb hauv kev rov ua dua thiab tsim cov khoom yas. Zaj duab xis ob-theem pelletising kab sawv cev rau kev nce qib loj hauv daim teb no, txhim kho kev ua tau zoo, zoo thiab ntau yam. Raws li qhov kev thov rau cov kev daws teeb meem yas txuas ntxiv mus ntxiv, qhov tseem ceeb ntawm kev siv tau zoopelletizing tshuabyuav nce txhua hnub. Los ntawm kev nqis peev hauv cov txheej txheem siab heev xws li zaj duab xis ob-theem pelletising kab, cov tuam txhab tuaj yeem pab txhawb rau yav tom ntej zoo dua thaum ua tau raws li cov kev xav tau ntawm lawv cov neeg siv khoom, yog li yog tias koj txaus siab rau zaj duab xis ob-theem pelletising kab, thov tsis txhob yig tiv tauj peb. tuam txhab.
