Ifilimu yepulasitiki iyigugu lesibili emakethe yokugaywa kabusha.Ifilimu egaywe kabusha ingasetshenziswa kabanzi ekukhiqizeni imikhiqizo ehlukahlukene.
Kukhona okuhlukile kokuma, usayizi, okuqukethwe umswakama kanye nokuqukethwe ukungcola kwefilimu yepulasitiki engcolile, Emakethe yokugaywa kabusha, amafilimu epulasitiki angahlukaniswa ngokuyisisekelo ngamaqembu alandelayo:
1.Ifilimu yezolimo(okuhlanganisa ifilimu yaphansi, ifilimu ebamba ukushisa kanye nefilimu yenjoloba nokunye.)
2.Ifilimu yangemuva kwabathengi(okuhlanganisa nokuqoqa ifilimu kudoti)
3.Post Commercial film and post industrial film(ikakhulukazi njengezikhwama zepulasitiki nefilimu yokupakisha)
Embonini yokugaywa kabusha kwepulasitiki, inkampani ye-PURUI inganikeza uchungechunge lwemigqa yokuwasha ethuthukisiwe kanye ne-pelletizing ukuze kusetshenziswe kabusha kahle zonke izinhlobo zezinto zepulasitiki.
Umshini wokuwasha ifilimu yepulasitiki, lo mugqa wonke wokukhiqiza usetshenziselwa ukuchoboza, ukugeza, ukukhipha amanzi kanye nefilimu eyomile ye-PP/PE, isikhwama esilukiwe se-PP.Kuthatha izinzuzo zesakhiwo esilula, ukusebenza okulula, umthamo ophezulu, ukusetshenziswa kwamandla okuphansi, ukuphepha, ukwethembeka.njll.
Icubungula izinyathelo:
isihambisi sebhande→icrusher→isilayishi sesikulufu esivundlile→iwasha isikulufu esinesivinini esiphezulu→ithangi lewasha elintantayo→isilayidi sesikulufu→umshini wokukhipha amanzi wefilimu→isilayishi sefilimu→isilayishi sethangi→ithange lewasha elintantayo→isilayishi sesikulufu→isilayishi sesikulufu esivundlile→isikhamo sepulasitiki→isitoreji sesililo.
Mayelana ne-crusher:
Isinyathelo sokuqala sokugaywa kabusha kwefilimu sikhiqiza ukugeleza okuzinzile kwemfucuza engenayo nge-crusher.Ukugeza kuqala ukungcola bese kwenzeka, kuqala ngokuyaluza nokususwa kokungcola, bese kulandela emathangeni okucwila okuntantayo ukuze kukhishwe ukungcola okusinda kakhulu.Lokhu kusebenza kunciphisa ukuguga kwemishini engxenyeni esele yomugqa.
Ifilimu Ehlanzekile ithunyelwa ku-granulator emanzi elandelwa i-centrifuge yokukhishwa kwamanzi kanye ne-pulp.Kulandela ithangi elinyakazayo nokuhlukanisa, ukuze kuqhutshekwe nokungcola.izinyathelo ezengeziwe ze-centrifugation zilandela ukususa ukungcola okuhle namanzi.Ukomisa okushisayo okuklanywe ngokukhethekile ngomoya oshisayo kuvumela ukususa umswakama wokugcina ngokuphumelelayo.
Mayelana nokomisa: isikhamo sepulasitiki/umshini wokomisa ipulasitiki/umshini wokucindezela
Umswakama ophansi, umthamo ophezulu
Isomisi sepulasitiki siyingxenye ebalulekile yomugqa wokuwasha amafilimu epulasitiki.
Amafilimu awashiwe agcina ubumanzi obufika ku-30% ngokujwayelekile.Umswakama ophezulu uzoba nomthelela ekusebenzeni kahle nokukhiqizwa kwenqubo elandelayo ye-pelletizing.
Ukuba ne-plastic squeeze dryer kuyadingeka ukuze ukhiphe amanzi efilimu egeziwe, unciphise umthamo wezinto ezigaywe kabusha futhi uqhubeke ucwenga ingqikithi yama-pellets okugcina epulasitiki.
Umswakamo wokugcina ungaphansi kuka-3% ngemva kokufakwa.
