Pelletising, njira yofunika kwambiri popanga zinthu zapulasitiki, imayang'ana pakubwezeretsanso ndi kupanga ma pellets apulasitiki, omwe ndi zida zopangira ntchito zosiyanasiyana monga kupanga filimu, kuumba jekeseni ndi kutulutsa. Pali njira zambiri zamakono zopangira ma pellets zomwe zilipo, zomwe mafilimu opanga mafilimu a bi-stage pelletising amawoneka kuti ali ndi zida zowonjezera komanso zogwira mtima kuti apange mapepala apamwamba kwambiri kuchokera ku zinyalala zapulasitiki.
Kutembenuza zipangizo monga mapulasitiki otayira kukhala ang'onoang'ono, ma pellets a yunifolomu ndi njira yowonongeka, ndipo njira yonse ya pellettising imaphatikizapo, kudyetsa, kusungunula, kutulutsa, kuzizira ndi kudula kuti apange mapepala omwe amatha kugwidwa mosavuta, kunyamulidwa ndi kukonzedwa m'magawo otsatirawa. za kupanga.
Tekinoloje ya Pelletizingakhoza kugawidwa mozama m'magulu awiri: pelletising ya gawo limodzi ndi magawo awiri. Pelletising imodzi yokha imagwiritsa ntchito extruder imodzi kuti isungunuke zinthu ndikupanga mapepala, pamene ma pellettising awiri amagwiritsira ntchito ma extruder awiri, kulola kuwongolera bwino kwambiri kwa kusungunuka ndi kuzizira, zomwe zimapangitsa mapepala apamwamba kwambiri.
Kanemayo magawo awirimzere wa pelletizingadapangidwa kuti azikonza mafilimu apulasitiki monga polyethylene (PE) ndi polypropylene (PP). Ukadaulowu ndiwoyenera kubwezanso mafilimu apulasitiki omwe angogula, omwe nthawi zambiri amakhala ovuta kuwakonza chifukwa chakuchepa kwawo komanso chizolowezi chomamatirana.
Kudyetsa ndi kukonzekera kusanachitike kumaphatikizapo kudyetsa kachipangizo ndi filimu ya pulasitiki, yomwe nthawi zambiri imang'ambika m'zidutswa zing'onozing'ono kuti zithandize kusamalira ndi kukonza. Kuchiza koyambirira kungaphatikizeponso kuyanika zinthuzo kuti zichotse chinyezi, zomwe ndizofunikira kuti zisungunuke bwino komanso kuti zisungunuke.
Mu gawo loyamba, filimu ya pulasitiki yophwanyika imadyetsedwa mu extruder yoyamba, yomwe imakhala ndi zomangira zomwe zimasungunula zinthuzo ndi kumeta ndi kutenthetsa. Pulasitiki yosungunukayo imakakamizika kudutsa pazenera kuti ichotse zonyansa ndikuwonetsetsa kusungunuka kofanana.

Kuchokera ku extruder yoyamba, zinthu zosungunula zimadutsa mu extruder yachiwiri, siteji yomwe imalola kuwonjezereka kwa homogenisation ndi degassing, zomwe ndizofunikira kuchotsa zotsalira zotsalira kapena chinyezi zomwe zingakhudze ubwino wa pellet yomaliza. Extruder yachiwiri nthawi zambiri imathamanga pa liwiro lotsika, lomwe limathandiza kusunga katundu wa pulasitiki.
Pambuyo pa gawo lachiwiri la extrusion, pelletiser imagwiritsidwa ntchito podula pulasitiki yosungunuka kukhala ma pellets, omwe amatha kukhazikika pansi pa madzi kapena mpweya, malingana ndi zofunikira zenizeni za kupanga. Ma pellets opangidwa ndi ofanana kukula kwake ndi mawonekedwe ake ndipo ndi oyenera ntchito zosiyanasiyana.
Ma pellets akapangidwa, amafunika kuzizira ndi kulimba, kenako zowuma kuti achotse chinyezi chochulukirapo. Kuziziritsa koyenera ndi kuyanika ndikofunikira kuti zitsimikizire kutimapepalasungani kukhulupirika kwawo ndipo musafooke.
Pomaliza, ma pellets amapakidwa kuti asungidwe kapena kunyamula, njira yochepetsera kuipitsidwa ndikuwonetsetsa kuti ma pellets ali mumkhalidwe wabwino kwambiri musanagwiritse ntchito.
M'munsimu muli zitsanzo za ubwino wa mzere wapawiri-gawo lopangira mafilimu:
- Mtundu wapamwamba wa pellet:ndondomeko ya magawo awiri imalola kulamulira bwino kwa kusungunuka ndi kuzizira, zomwe zimapangitsa ma pellets apamwamba omwe ali ndi thupi labwino.
- Kuchotsa zonyansa kwambiri:Njira ziwiri zowonjezera zowonjezera zimachotsa bwino zowonongeka ndi zowonongeka, zomwe zimapangitsa kuti pellets ikhale yoyera, yosasinthasintha.
- Kusinthasintha:Ukadaulo umatha kukonza makanema ambiri apulasitiki, ndikupangitsa kuti akhale oyenera kugwiritsa ntchito mitundu yosiyanasiyana yobwezeretsanso.
- Kuchita bwino kwamagetsi:Machitidwe a bipolar amapangidwa kuti azidya mphamvu zochepa kusiyana ndi machitidwe amodzi, kuwapangitsa kukhala okhazikika.
- Kuchepetsa nthawi yopuma:kamangidwe koyenera ka filimuyo bi-stage pelletising line amachepetsa kutsika panthawi yopanga, zomwe zimapangitsa kuti pakhale zokolola zambiri komanso zokolola.
Ukadaulo wa pelletising umagwira ntchito yofunika kwambiri pakubwezeretsanso ndi kupanga zinthu zapulasitiki. Mafilimu amizere iwiri ya pellettising imayimira kupita patsogolo kwakukulu mu ntchitoyi, kupititsa patsogolo bwino, khalidwe komanso kusinthasintha. Pamene kufunikira kwa mayankho okhazikika apulasitiki kukukulirakulira, kufunika kogwira ntchitoteknoloji ya pelletizingzidzawonjezeka tsiku ndi tsiku. Poikapo ndalama mu machitidwe apamwamba monga filimu ya magawo awiri a pelletising mizere, opanga amatha kuthandizira tsogolo lokhazikika pamene akukumana ndi zosowa za makasitomala awo, kotero ngati mukufuna filimuyi mizere iwiri ya pelletising, chonde musazengereze kulumikizana ndi athu. kampani.
