Iyiphi ifilimu engcono kakhulu yemithi ezwela kakhulu umswakama?

Ayikho impendulo yendawo yonke. I-High-PVDC, PC Izakhiwo ze-aluminium ezisuselwe ku-TFE noma ezipholile zingase zihlolwe uma kudingeka ukudluliswa komhwamuko ophansi kakhulu. Isinqumo sokugcina kufanele sisekelwe ekuzinzeni kwezidakamizwa kanye nedatha yokuqinisekisa ukupakishwa.

Isiphi isakhiwo esifanele imikhiqizo engezwani komoyampilo?

Izakhiwo ezinezendlalelo eziningi eziqukethe i-EVOH zingaba amakhandidethi aqinile lapho ukuvikelwa komoyampilo kuyisidingo esiyinhloko. I-PVDC nezinye izakhiwo ezinezithiyo eziphezulu nazo zingacatshangelwa kuye ngomswakama, ukwakheka kanye nezidingo zokulawula.

Ingabe ukupakishwa kwe-EVOH kwezemithi kungagaywa kabusha?

Ukuphinda kusetshenziswe kabusha kuncike esakhiweni sezendlalelo eziningi esiphelele, amaphesenti e-EVOH, amanye ama-polymer, okokusebenza kwesivalo kanye nomfudlana wendawo wokugaya kabusha. Ukuba khona kwe-EVOH kukodwa akufakazeli ukuthi iphakheji lekhemisi eliqediwe lingaphinda lisetshenziswe.

Ingabe kufanele ifilimu yamabhamuza eyenziwe ngokwenza imithi ihlolwe ngaphambi kwe-oda lokuthengisa?

Yebo. Abathengi kufanele bahlole ukwakheka, ukubekwa uphawu, ukuphrinta lapho kufanele khona, ukuzinza kohlangothi, ubuqotho bephakethe eliqediwe kanye nokusebenza kwesithiyo okudingekayo empahleni yokupakisha ehlosiwe ngaphambi kweziqu zentengiso.

Khetha Isakhiwo Sokupakisha Kumfuneko Yezidakamizwa, Hhayi Igama LePolymer

PVC , i-PVDC, i-EVOH ne-LDPE akufanele ibhekwe nje njengamafilimu amane aqhudelanayo ekhemisi. I-polymer ngayinye yenza umsebenzi ohlukile, futhi ukupakishwa kwe-multilayer kusebenza ngokuhlanganisa leyo misebenzi ibe isakhiwo esifaniswe nomkhiqizo wemithi.

PVC inikeza ukuqina kanye ne-thermoforming. I-PVDC ithuthukisa umswakama kanye nokuvimbela umoya-mpilo. I-EVOH inikeza ukuvikelwa komoyampilo okuqinile negesi kodwa ngokuvamile idinga izendlalelo ezizungezile ezivikela umswakama. I-LDPE ihlinzeka ngokuvala futhi inikele ngokuvikela umswakama ngaphakathi komklamo wezendlalelo eziningi.

Ukuze uthole iphrojekthi entsha yokupakisha yemithi, nikeza i-Wallis ngesakhiwo sakho samanje, i-OTR ne-WVTR eqondiwe, ukushuba kwefilimu, i-cavity geometry, ulwazi lomshini wamabhamuza, imininingwane eyisivalo, isimo sezulu okuyiwa kuso kanye nenani elidingekayo ukuze impahla efanele ihlolwe ukuze kutholwe isampula yokufaneleka.
