Ukungafihlisi okuphezulu kunceda ekuchongeni iimpahla;ubude bobude obuphezulu bunceda ukolula kwangaphambili kunye nokugcina ukusetyenziswa kwezinto;ukusebenza kakuhle kwe-puncture kunye namandla okukrazula okunqamlezayo kuvumela ifilimu ukuba idibane neekona ezibukhali okanye Umphetho awuphuli;inqanaba lesivuno esikhulu lenza iimpahla ezipakishiweyo ziqine ngakumbi.
Ifilimu eveliswe yindlela yokuphosa inokucaca okuphezulu.Ngokunyuka kwenani le-athomu ze-C ze-comonomer yezinto eziphathekayo, ubude betsheyini yesebe buyanda, i-crystallinity iyancipha, kunye nefuthe "lomoya okanye i-kinking" yesiphumo se-copolymer esonyuka, ngoko ke ukunyuka kuyanda, kunye namandla okubhoboza kunye amandla eenyembezi nawo ayanda.Kwaye i-MPE i-polymer e-stereoregular kakhulu kunye nokusabalalisa ubunzima be-molecular, obunokulawula ngokuchanekileyo iimpawu ezibonakalayo zepolymer, ngoko ukusebenza kwayo kuphuculwe ngakumbi;kwaye ngenxa yokuba i-MPE inokusabalalisa ubunzima bemolekyuli kunye noluhlu olumxinwa lokucubungula, kunzima ukulawula iimeko zokucwangcisa.Yongeza i-5% ye-LDPE ukunciphisa i-viscosity enyibilikayo kunye nokwandisa i-flatness yefilimu.
Ixabiso le-MPE nalo liphezulu.Ukuze kuncitshiswe iindleko, i-MPE idla ngokusetyenziswa ngokudibanisa ne-C4-LLDPE, kodwa ayizizo zonke i-C4-LLDPE ezinokudityaniswa nayo, ngoko ke kufuneka kubekho ukhetho.Ukusetyenziswa kweefilim zokolulwa komatshini ubukhulu becala zisebenzisa izixhobo ze-C6 kunye ne-C8, ekulula ukusetyenzwa kwaye zinokuhlangabezana neemfuno ezahlukeneyo zokupakisha.Ukupakishwa kwencwadana, izinto zeC4 zisetyenziswa kakhulu ngenxa yomlinganiselo ophantsi wokwelula.
Ukuxinana kwezinto kuchaphazela nokusebenza kwefilimu.Njengoko ingxinano isanda, iqondo lokuqhelaniswa liyanda, ukuba tyaba kulungile, ukomelela kobude kuyenyuka, kwaye amandla esivuno ayanda, kodwa amandla okukrazula anqamlezayo, amandla okugqobhoza kunye nokuhanjiswa kokukhanya konke kuyancipha.Ngoko ke, ukusebenza ngokubanzi kwayo yonke imiba ihlala ikwi-non-sticky Yongeza ubungakanani obufanelekileyo be-medium density linear polyethylene (LMDPE) kumaleko.Ukongeza i-LMDPE kunokunciphisa i-coefficient of friction ye-non-sticky layer kwaye ugweme ukunamathela kwi-pallet epakishwe kwi-pallet.
Impembelelo yobushushu bomqulu wokupholisa.Njengoko iqondo lokushisa lomqulu wokupholisa likhula, amandla okuvelisa ayanda, kodwa ezinye iimpawu ziyancipha.Ngoko ke, ubushushu bomqulu wokupholisa I ngokuqhelekileyo bulawulwa kuma-20°C ukuya kuma-30°C.Ukunyanzeliswa komgca wokuphosa kuchaphazela i-flatness kunye ne-winding tightness yefilimu.Ukuba i-PIB okanye i-masterbatch yayo isetyenziswe njengoluhlu olunamathele, iphinda ichaphazele ukufuduka kwe-PIB kwaye inciphisa i-viscosity yokugqibela yefilimu.Uxinzelelo alukho ngaphezu kwe-10kg.Uxinzelelo oluninzi luya kuhlala kuluhlu lwefilimu, oluya kunciphisa ubude kunye nezinye iipropathi kwaye zibangele ukuphuka kwefilimu ngokulula.Ifomu yesicelo sefilimu eyolulayo
Ifilimu eyoluliweyo inoluhlu olubanzi lwezicelo, ezisetyenziswa ikakhulu ngokubambisana neepaliti, ukupakisha iimpahla ezihlakazekileyo ngobuninzi, endaweni yezikhongozeli ezincinci.Ngenxa yokuba inokunciphisa iindleko zokuthuthwa kwempahla eninzi kunye nokupakishwa ngaphezu kwe-30%, isetyenziswa ngokubanzi kwipakethe epheleleyo yeemveliso ezahlukeneyo ezifana ne-hardware, iiminerali, iikhemikhali, amayeza, ukutya, oomatshini, njl.;kwintsimi yokugcina indawo yokugcina impahla, iphinda isetyenziswe ngakumbi ngaphandle.Iipalethi zefilimu ezolula zipakishwe ukuze zigcinwe macala-ntathu kunye nokuthutha ukugcina indawo kunye nomsebenzi.
