Kev ua cov yas ua kom puv, yog ib qho txheej txheem tseem ceeb hauv kev tsim cov khoom yas, tsom mus rau kev siv dua tshiab thiab kev tsim cov yas ua kom puv, uas yog cov khoom siv raw rau ntau yam kev siv xws li kev tsim zaj duab xis, kev txhaj tshuaj molding thiab extrusion. Muaj ntau yam thev naus laus zis ua kom puv muaj, ntawm cov kab ntau lawm ua kom puv zaj duab xis bi-stage sawv tawm tias muaj kev ua haujlwm zoo dua thiab ua tau zoo dua los tsim cov yas ua kom puv zoo los ntawm cov khoom siv yas pov tseg.
Kev hloov cov khoom siv raw xws li cov yas pov tseg mus rau hauv cov pellets me me, sib xws yog cov txheej txheem ntawm pelletising, thiab tag nrho cov txheej txheem ntawm pelletising suav nrog, pub mov, yaj, extruding, txias thiab txiav los tsim cov pellets uas tuaj yeem yooj yim tuav, thauj thiab ua tiav hauv cov theem tom ntej ntawm kev tsim khoom.
Cov txheej txheem pelletizingmuaj peev xwm muab faib ua ob pawg: ib theem pelletising thiab ob theem pelletising. Ib theem pelletising siv ib lub extruder los yaj cov khoom thiab ua cov pellets, thaum ob theem pelletising siv ob lub extruders, uas tso cai rau kev tswj hwm qhov tseeb ntawm cov txheej txheem yaj thiab txias, ua rau cov pellets zoo dua.
Zaj yeeb yaj kiab ob theemkab pelletizingyog tsim los rau kev ua cov yas yas xws li polyethylene (PE) thiab polypropylene (PP). Cov thev naus laus zis no tsim nyog rau kev rov ua dua cov yas yas uas siv lawm, uas feem ntau nyuaj rau kev ua vim lawv qhov ceev tsawg thiab nyiam lo ua ke.
Kev pub thiab kev ua ua ntej suav nrog kev pub cov yas seem rau hauv lub tshuab ua ntej, uas feem ntau raug rhuav ua tej daim me me kom yooj yim rau kev tuav thiab ua. Kev kho ua ntej kuj tseem yuav suav nrog kev ziab cov khoom kom tshem tawm cov dej noo, uas yog qhov tseem ceeb rau kev yaj thiab ua kom cov khoom me me.
Thaum xub thawj, cov yas yas uas raug muab txiav ua tej daim me me lawm ces muab tso rau hauv lub tshuab extruder thawj zaug, uas muaj lub hau ntswj uas yaj cov khoom siv los ntawm kev txiav thiab cua sov. Cov yas uas yaj lawm ces raug thawb los ntawm lub ntxaij lim dej kom tshem tawm cov khoom tsis huv thiab xyuas kom meej tias yaj sib npaug.
Ntxig, thov xav txog peb lub tuam txhab cov khoom no,LQ250-300PE Zaj Duab Xis Ob Chav-Theem Pelletizing Kab
Los ntawm thawj lub extruder, cov khoom siv molten dhau mus rau hauv lub extruder thib ob, ib theem uas tso cai rau kev sib xyaw ua ke thiab degassing ntxiv, uas yog qhov tseem ceeb kom tshem tawm cov khoom seem lossis cov dej noo uas yuav cuam tshuam rau qhov zoo ntawm cov pellet kawg. Lub extruder thib ob feem ntau khiav ntawm qhov ceev qis dua, uas pab tswj cov khoom ntawm cov yas.
Tom qab theem ob ntawm kev rho tawm, lub tshuab pelletiser siv los txiav cov yas uas yaj ua pellets, uas tuaj yeem txias hauv qab dej lossis los ntawm huab cua, nyob ntawm qhov xav tau tshwj xeeb ntawm cov txheej txheem tsim khoom. Cov pellets tsim tawm yog sib xws hauv qhov loj me thiab cov duab thiab tsim nyog rau ntau yam kev siv.
Thaum cov pellets raug pwm lawm, lawv yuav tsum tau txias thiab khov, thiab tom qab ntawd ziab kom tshem tawm cov dej noo ntau dhau. Kev txias thiab ziab kom zoo yog qhov tseem ceeb kom ntseeg tau tiascov hmoov me metswj lawv txoj kev ncaj ncees thiab tsis txhob sib sau ua ke.
Thaum kawg, cov pellets raug ntim rau kev khaws cia lossis kev thauj mus los, ib qho txheej txheem tsim los txo qis kev ua qias tuaj 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 cov kab pelletising ob theem rau cov yeeb yaj kiab:
- Zoo dua pellet:cov txheej txheem ob theem tso cai rau kev tswj hwm zoo dua ntawm cov txheej txheem yaj thiab txias, ua rau cov pellets zoo dua nrog cov khoom zoo dua.
- Kev tshem tawm cov kuab paug ntau dua:Cov txheej txheem extrusion ob-theem tshem tawm cov pa phem thiab cov volatile, ua rau cov pellets huv dua thiab sib xws dua.
- Kev siv tau ntau yam:Cov thev naus laus zis no tuaj yeem ua tiav ntau yam yas zaj duab xis, ua rau nws tsim nyog rau ntau yam kev siv rov ua dua tshiab.
- Kev siv hluav taws xob zoo:Cov kab ke bipolar feem ntau yog tsim los siv hluav taws xob tsawg dua li cov kab ke ib theem, ua rau lawv yog qhov kev xaiv ruaj khov dua.
- Txo lub sijhawm tsis ua haujlwm:qhov kev tsim qauv zoo ntawm cov yeeb yaj kiab bi-stage pelletising kab txo qis lub sijhawm tsis ua haujlwm thaum lub sijhawm tsim khoom, ua rau muaj kev tsim khoom ntau ntxiv thiab kev tsim khoom.
Kev siv tshuab pelletising ua lub luag haujlwm tseem ceeb hauv kev rov ua dua tshiab thiab kev tsim cov khoom yas. Cov kab pelletising ob theem yog ib qho kev nce qib loj hauv daim teb no, txhim kho kev ua haujlwm zoo, zoo thiab kev hloov pauv tau yooj yim. Raws li qhov kev thov rau cov kev daws teeb meem yas ruaj khov txuas ntxiv mus, qhov tseem ceeb ntawm kev ua haujlwm zookev siv tshuab ua kom cov khoom me meyuav nce ntxiv txhua hnub. Los ntawm kev nqis peev rau hauv cov txheej txheem siab heev xws li cov kab ua los ntawm zaj duab xis ob theem pelletising, cov chaw tsim khoom tuaj yeem pab txhawb rau yav tom ntej uas ruaj khov dua thaum ua tau raws li qhov xav tau ntawm lawv cov neeg siv khoom, yog li ntawd yog tias koj xav tau cov kab ua los ntawm zaj duab xis ob theem pelletising, thov tsis txhob yig tiv tauj peb lub tuam txhab.
