I-Pelletising, inkqubo ephambili ekuvelisweni kweemveliso zeplastiki, igxile ekusetyenzisweni kwakhona nasekuvelisweni kwee-pellets zeplastiki, ezizezona zinto zisetyenziswayo kwiintlobo ngeentlobo zezicelo ezifana nokuveliswa kweefilimu, ukubumba ngenaliti kunye nokukhupha ii-pellets. Kukho iindlela ezahlukeneyo zobuchwepheshe bokwenza ii-pelletising ezikhoyo, phakathi kwazo umgca wokuvelisa ii-pelletising zefilimu ezikwinqanaba eliphakathi ubonakala uxhotyiswe ngakumbi ngokusebenza kakuhle nangokusebenza kakuhle ukuvelisa ii-pellets ezikumgangatho ophezulu ngezinto ezilahliweyo zeplastiki.
Ukuguqula izinto eziluhlaza ezifana neeplastiki ezilahliweyo zibe ziipellet ezincinci, ezifanayo yinkqubo yokwenza iipellet, kwaye yonke inkqubo yokwenza iipellet ibandakanya, ukondla, ukunyibilikisa, ukukhupha, ukupholisa kunye nokusika ukuze kwenziwe iipellets ezinokuphathwa lula, zithuthwe kwaye zicutshungulwe kwizigaba ezilandelayo zemveliso.
Iitekhnoloji zokufaka iipelletIngahlulwa-hlulwa ngokubanzi ibe ziindidi ezimbini: i-single-stage pelletising kunye ne-two-stage pelletising. I-single-stage pelletising isebenzisa i-extruder enye ukunyibilikisa izinto nokwenza ii-pellets, ngelixa i-two-stage pelletising isebenzisa ii-extruder ezimbini, okuvumela ulawulo oluchanekileyo lwenkqubo yokunyibilikisa kunye nokupholisa, nto leyo ekhokelela kwi-pellets esemgangathweni ophezulu.
Ifilimu enamanqanaba amabiniumgca wokutsala iipelletYenzelwe ukucubungula iifilimu zeplastiki ezifana ne-polyethylene (PE) kunye ne-polypropylene (PP). Le teknoloji ifanelekile ngokukodwa ekusetyenzisweni kwakhona kweefilimu zeplastiki emva komthengi, ezihlala zinzima ukuzicubungula ngenxa yoxinano lwazo oluphantsi kunye nokuthambekela kokunamathelana.
Ukondla kunye nokulungisa izinto ngaphambi kokuba zisetyenziswe kubandakanya ukondla inkqubo kuqala ngeeplastiki ezisele, ezidla ngokukrazulwa zibe ziingceba ezincinci ukuze kube lula ukuziphatha nokuzilungisa. Ukulungisa izinto ngaphambi kokuba zisetyenziswe kungabandakanya ukomisa izinto ukuze kususwe umswakama, nto leyo ebalulekileyo ekunyibilikiseni nasekufakeni i-pellet.
Kwinqanaba lokuqala, ifilimu yeplastiki eqwengiweyo ifakwa kwi-extruder yokuqala, exhotyiswe ngesikrufu esinyibilikisa izinto ngokucheba nokufudumala ngoomatshini. Emva koko iplastiki enyibilikisiweyo inyanzeliswa ukuba idlule kwiscreen ukususa ukungcola nokuqinisekisa ukuba inyibilika ngokulinganayo.

Ukusuka kwi-extruder yokuqala, izinto ezinyibilikisiweyo zidlulela kwi-extruder yesibini, inqanaba elivumela ukuba kubekho i-homogenisation kunye ne-degassing engaphezulu, nto leyo ebalulekileyo ukususa naziphi na izinto ezishiyekileyo okanye ukufuma okunokuchaphazela umgangatho we-pellet yokugqibela. I-extruder yesibini idla ngokuqhutywa ngesantya esiphantsi, nto leyo enceda ukugcina iimpawu zeplastiki.
Emva kwesigaba sesibini sokukhupha, i-pelletiser isetyenziselwa ukusika iplastiki enyibilikisiweyo ibe zii-pellets, ezinokupholiswa phantsi kwamanzi okanye ngomoya, kuxhomekeke kwiimfuno ezithile zenkqubo yokuvelisa. Ii-pellets eziveliswayo ziyafana ngobukhulu kunye nemilo kwaye zifanelekile kwiintlobo ngeentlobo zezicelo.
Nje ukuba iipellets zibunjwe, kufuneka zipholiswe kwaye ziqine, emva koko zomiswe ukuze kususwe umswakama ogqithisileyo. Ukupholisa nokomisa ngokufanelekileyo kubalulekile ukuqinisekisa ukubaiipelletsbagcine ingqibelelo yabo kwaye bangagobi.
Okokugqibela, iipellets zipakishwa ukuze zigcinwe okanye zithuthwe, inkqubo eyenzelwe ukunciphisa ungcoliseko nokuqinisekisa ukuba iipellets zikwimeko entle ngaphambi kokuba zisetyenziswe.
Apha ngezantsi kukho imizekelo yezibonelelo zomgca we-pelletising onezigaba ezimbini kwiifilimu:
- Umgangatho ophezulu wepellet:Inkqubo enamanqanaba amabini ivumela ulawulo olungcono lwenkqubo yokunyibilikisa nokupholisa, nto leyo ekhokelela kwiipellets ezikumgangatho ophezulu ezineempawu zomzimba eziphuculweyo.
- Ukususwa kongcoliseko oluphezulu:Inkqubo yokukhupha enezigaba ezibini isusa ngokufanelekileyo ungcoliseko kunye nokubola, nto leyo ephumela kwiipellets ezicocekileyo nezihlala zihleli.
