Filimu yapulasitiki ndi yamtengo wapatali gwero lachiwiri pamsika wobwezeretsanso.Mafilimu obwezerezedwanso amatha kugwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana.
Pali zosiyana ndi mawonekedwe, kukula, chinyezi ndi zonyansa za filimu yapulasitiki yonyansa, Mumsika wobwezeretsanso, mafilimu apulasitiki akhoza kugawidwa m'magulu otsatirawa:
1.Filimu yaulimi (kuphatikiza filimu yapansi, filimu yowonjezera kutentha ndi filimu ya rabara ndi zina zotero)
2.Post-consumer film(kuphatikiza kutolera filimu ku zinyalala)
3.Post Commercial film and post industry film (makamaka ngati matumba apulasitiki ndi filimu yolongedza)
Mu makampani yobwezeretsanso pulasitiki, PURUI kampani angapereke mndandanda wa bwino anayamba kutsuka ndi mizere pelletizing kwa yobwezeretsanso bwino mitundu yonse ya zinthu mapulasitiki.
Makina ochapira filimu apulasitiki, mzere wonsewu umagwiritsidwa ntchito kuphwanya, kutsuka, kuthira madzi ndi filimu yowuma ya PP/PE, thumba loluka la PP.Zimatengera ubwino wa dongosolo losavuta, ntchito yosavuta, mphamvu zambiri, kugwiritsa ntchito mphamvu zochepa, chitetezo, kudalirika.Ndi zina zotero.
Pokonza masitepe:
lamba wonyamulira → chophwanyira → chopingasa wononga wononga → chowotcha wononga → thanki yoyandama → chopatulira → makina othira madzi → chopatulira filimu → tanki yoyandama → chopatulira → chopingasa wononga wononga → chofinyira pulasitiki → chosungiramo silo.
Za crusher:
Gawo loyamba pakubwezeretsanso filimu ndikupanga kuyenda kosasunthika kwa zinyalala zomwe zikubwera kudzera mu chopuntha.Kutsukidwa kochotsa kuipitsidwa kumayambika, koyambilira ndi chipwirikiti ndi kuipitsidwa, kenaka m’matangi oyandama kuti achotse zolemera kwambiri.Opaleshoniyi imachepetsa kuvala kwa makina mu gawo lotsala la mzere.
Precleaned Film imatumizidwa ku granulator yonyowa yotsatiridwa ndi centrifuge yochotsa madzi ndi zamkati.Tanki yosonkhezera ndi yolekanitsa imatsatira, kuti muwonongedwenso.masitepe owonjezera a centrifugation amatsata kuchotsa zoyipitsidwa bwino ndi madzi.Kuyanika kwapadera kopangidwa mwapadera ndi mpweya wotentha kumalola kuchotsa chinyezi chomaliza.
Za kuyanika: pulasitiki squeezer / pulasitiki drier / squeezer makina
Low chinyezi, mkulu mphamvu
Chowumitsira pulasitiki ndi gawo lofunika kwambiri la mzere wochapira mafilimu apulasitiki.
Mafilimu ochapitsidwa amasunga mpaka 30% kunyowa nthawi zonse.Kunyezimira kwakukulu kudzakhudza kugwira ntchito bwino ndi kupanga njira yotsatirayi ya pelletizing.
Kukhala ndi chowumitsira pulasitiki ndikofunikira kuti muchotse madzi m'thupi la filimu yotsuka, kuchepetsa kuchuluka kwa zinthu zobwezerezedwanso ndikuyeretsanso ma pellets apulasitiki omaliza.
Final chinyezi zosakwana 3% pambuyo porocessed.
