Isikhwama Sokudla Kwezilwane Ezifuywayo

Njengamanje, izikhwama zokufaka ukudla eziqandisiwe emakethe zingahlukaniswa ikakhulukazi izikhwama zokupakisha ezinongqimba olulodwa, izikhwama zokupakisha eziyinhlanganisela, kanye nezikhwama zokupakisha ezinezingqimba eziningi. Ipulasitiki ethambile eyinhlanganisela isetshenziswa kakhulu ezikhwameni zokufaka ukudla eziqandisiwe, futhi lolu hlobo lwezikhwama zokufaka ukudla eziqandisiwe luphinde lube nezinhlanganisela eziningi ekwakhiweni kwezinto ezibonakalayo.

Ngokusho kokuqukethwe, kunezinhlobo eziningana ezingasetshenziselwa ukupakisha ukudla okufriziwe. Eyodwa, PET/PE. Lesi sakhiwo sempahla sivame kakhulu ekufakweni kwemikhiqizo yokudla eqandiswe ngokushesha. Inokumelana okuhle nomswakama, ukumelana nokubanda, nokusebenza kokuvala izinga lokushisa eliphansi lokushisa, futhi izindleko zokukhiqiza ziphansi kakhulu.

Okwesibili, i-BOPP/PE ne-BOPP/CPP. Izikhwama eziqandisiwe zokupakisha ukudla zalezi zakhiwo ezimbili zinokumelana nomswakama okuhle kakhulu kanye nokumelana nokubanda, amandla okubamba ukushisa okuqinile okubamba ukushisa okuphansi, kanye nomnotho omuhle. Kuhle ukusho ukuthi impahla ye-BOPP/PE izizwa ingcono kune-PET/PE, elungele ukumakethwa komkhiqizo.

Okwesithathu, i-PET/VMPET/CPE, BOPP/VMPET/CPE. Uma kuqhathaniswa nezikhwama zokupakisha ezinesendlalelo esisodwa kanye nesendlalelo esikabili, isakhiwo esinezingqimba ezintathu siqine kakhulu futhi sizinzile, futhi sinomsebenzi ophezulu wokuvinjelwa. Ngaphezu kwalokho, ukuba khona kwesendlalelo se-aluminium nakho kunenzuzo evelele ekusebenzeni kokuphrinta. Kodwa-ke, uma kuqhathaniswa nezinto ezingenhla, izinga lokushisa eliphansi lokushisa okushisayo Ukusebenza okungalungile kokuvala uphawu kanye nezindleko eziphezulu Okwesine, i-PA/PE, i-PET/PA/LLDPE, i-PET/PA/AL/PE, i-PA/PE. Isakhiwo salezi zinhlobo ezine zezinto ezisetshenziswayo simelana kakhulu neqhwa kanye nomthelela, futhi ungqimba lwe-PA luqinisekisa ukumelana nokubhoboza okuhle. Ububi ukuthi izindleko zokukhiqiza ziphezulu, futhi ngokuvamile zisetshenziselwa ukupakishwa kwe-angular noma okusindayo komkhiqizo wokudla.
