Amafilimu e-LDPE ngokuvamile enziwa yizo zombili izinqubo zokubumba nokuphonsa. Ifilimu ye-Cast polyethylene inobukhulu obufanayo, kodwa ayivamile ukusetshenziswa ngenxa yentengo yayo ephezulu. Ifilimu ye-polyethylene eshaywayo yenziwa ngamapellets e-PE ebanga ngokushaywa ngemishini yokubumba, okuyiyona esetshenziswa kakhulu ngenxa yezindleko zayo eziphansi.

Ifilimu ye-polyethylene ye-low-density iyi-semi-transparent, ecwebezelayo, ukuthungwa okuthambile kwefilimu, enokuqina okuhle kwamakhemikhali, ukuvalwa kokushisa, ukumelana kwamanzi nokumelana nomswakama, ukumelana nokuqandisa, kungabiliswa. I-drawback yayo eyinhloko isithiyo esimpofu somoya-mpilo, esivame ukusetshenziswa ezintweni zokupakisha eziguquguqukayo eziyinhlanganisela, ungqimba lwangaphakathi lwefilimu, kodwa futhi okwamanje yilona olusetshenziswa kabanzi kakhulu, inani elikhulu kunawo wonke lefilimu yokupakisha yepulasitiki, ebalwa ngaphezu kuka-40% wefilimu. ukusetshenziswa kwefilimu yokupakisha yepulasitiki.

Njengoba i-molecule ye-polyethylene ingenawo amaqembu e-polar futhi inezinga eliphezulu le-crystallinity namandla aphansi akhululekile, ifilimu inezindawo zokunyathelisa ezimbi kanye nokunamathela okubi kumayinki nama-adhesives, ngakho-ke ukwelashwa kwendawo kuyadingeka ngaphambi kokunyathelisa nokukhipha i-laminating.

Okulandelayo ukwehluleka okuvamile kanye nezixazululo zefilimu evuthelwe yi-LDPE:

Ifilimu inamathela kakhulu, ayivuleki kahle

Ukuhlaziya imbangela:

1. I-resin eluhlaza ayilona uhlobo olulungile, hhayi i-resin yezinga lefilimu ephethiwe ye-LDPE, engenayo i-ejenti yokuvula noma i-ejenti yokuvula isezingeni eliphansi;

2. Izinga lokushisa le-resin encibilikisiwe liphezulu kakhulu, i-fluidity inkulu kakhulu;

3. Isilinganiso sokushaywa sikhulu kakhulu, okuholela ekuvulekeni kwefilimu okungekuhle;

4. Ijubane lokupholisa lihamba kancane, ifilimu ayipholile ngokwanele, futhi ukuhlangana okuhlangene kwenzeka ngaphansi kwesenzo sokucindezela kwe-traction roller;

5. Isivinini sokudonsa sishesha kakhulu.

Izixazululo

Ukungafihli kahle kwefilimu

Ukuhlaziya imbangela:

1. izinga lokushisa eliphansi le-extrusion, ipulasitiki ye-resin empofu, okuholela ekuhleleni obala kwefilimu ngemuva kokubunjwa kokushaywa;

2. Isilinganiso sokushaywa sincane kakhulu;

3. Umphumela wokupholisa ongemuhle, ngaleyo ndlela uthinte ukubonakala kwefilimu;

4. Umswakamo ku-resin impahla eluhlaza mkhulu kakhulu;

5. Ijubane lokudonsa lishesha kakhulu futhi ifilimu ayipholile ngokwanele.

Isixazululo

① Khulisa ngokufanelekile izinga lokushisa le-extrusion, ukuze inhlaka ibe ipulasitiki ngendlela efanayo;

② Khulisa ngokufanelekile isilinganiso sokushaywa;

③Khulisa ivolumu yomoya ukuze uthuthukise umphumela wokupholisa;

③ Khulisa ivolumu yomoya ukuze uthuthukise umphumela wokupholisa;

Imibimbi yefilimu

Ukuhlaziya imbangela

1. Ubukhulu befilimu obungalingani;

2. Umphumela wokupholisa onganele;

3. Isilinganiso sokuphefumula sikhulu kakhulu, okwenza ukuba i-bubble yefilimu ingazinzi, iguqukela emuva naphambili ukusuka kolunye uhlangothi kuya kolunye, ngakho-ke ifilimu ijwayele ukushwabana;

4. I-angle ye-herringbone clamp inkulu kakhulu, i-bubble yefilimu igxiliwe ebangeni elifushane, ngakho-ke ifilimu nayo ijwayele ukushwabana;

5. Ukucindezela ezinhlangothini zombili ze-roller traction ayihambisani, uhlangothi olulodwa luphakeme kanti olunye luphansi;

6. Izimbazo phakathi kwama-roller omhlahlandlela azihambisani, okuthinta ukuzinza nokuqina kwefilimu, ngaleyo ndlela ukushwabana kwenzeka.

Isixazululo

① Lungisa ukushuba kwefilimu ukuze uqinisekise ukushuba okufanayo;

② Thuthukisa umphumela wokupholisa ukuze uqinisekise ukuthi ifilimu ingapholiswa ngokugcwele;

④ Yehlisa i-engeli yokubamba ye-herringbone clamp ngokufanelekile;

⑤ Lungisa ingcindezi ye-traction roller ukuze uqinisekise ukuthi ifilimu ingaphansi kwamandla afanayo;

⑥ Hlola i-eksisi yeshafu ngayinye yomhlahlandlela bese ubenza baqondane.

Ukusebenza okungalungile kokuvalwa kokushisa kwefilimu

Ukuhlaziya imbangela

1. Umugqa wesithwathwa uphansi kakhulu, ama-molecule e-polymer athola umumo, ngaleyo ndlela enze ukusebenza kwefilimu kusondele kulokho kwefilimu eqondisiwe, okuholela ekusebenzeni okuphansi kokuvalwa kokushisa;

2. Isilinganiso sokuvuthela kanye nesilinganiso sokudonsa sikhulu kakhulu, futhi ifilimu ithola umumo owelulayo, ngaleyo ndlela kuthinte ukusebenza kokuvala ukushisa kwefilimu.

Isixazululo

① Lungisa usayizi wevolumu yomoya eringini yomoya ukuze wenze amazolo akhombe phezulu kancane, ngangokunokwenzeka, ngaphansi kwendawo yokuncibilika yokuvunguza nokudonsa kwepulasitiki, ukuze kwehliswe ama-molecule ngenxa yokuvunguza nokudonsa okubangelwa ukwelula orientation;

② Izilinganiso zokuvuthela nokudonsa kufanele zibe zincane ngokufanelekile. Uma isilinganiso sokufutha sisikhulu kakhulu futhi isivinini sokudonsa sishesha kakhulu, ifilimu yeluliwe ngendlela ephambanayo kanye nezikhombisi-ndlela ze-longitudinal, khona-ke ukusebenza kwefilimu kuvame ukunwebeka kabili, futhi izici zokuvala ukushisa kwefilimu zizoba zimbi.

Ifilimu inephunga

Ukuhlaziya imbangela

1. I-resin eluhlaza ngokwayo inephunga;

2. Izinga lokushisa le-extrusion le-resin encibilikisiwe liphezulu kakhulu, elibangela ukuba i-resin ibole, ngaleyo ndlela ikhiqize iphunga;

3. Ukupholisa okunganele kwebhamuza lefilimu, umoya oshisayo ngaphakathi kwebhamuza lefilimu awususiwe.

Isixazululo

① Faka esikhundleni inhlaka eluhlaza;

② Lungisa izinga lokushisa le-extrusion;

③Thuthukisa ukusebenza kahle kokupholisa kweringi yomoya opholisayo, ukuze ibhamuza lefilimu lipholiswe ngokwanele.

Imvula emhlophe phezu kwefilimu

Isizathu: Ngokuyinhloko izithasiselo ezitholakala ezintweni ezingavuthiwe, ama-resin esisindo samangqamuzana aphansi kanye nothuli, njll., ajiya emlonyeni wesikhunta ngesikhathi sokucutshungulwa, futhi ngemva kokuqongelela inani elithile liyasuswa ifilimu ngokuqhubekayo, ngaleyo ndlela kwakheka ama-White precipitates efilimu.

Isixazululo

①Ngemuva kwesikhathi esithile, khulisa isivinini sesikulufu, ukhuphule ingcindezi ye-ncibilika ye-extrusion, ususe imvula.

② Hlanza isikhunta emlonyeni njalo.

③ Khulisa izinga lokushisa lokuncibilika ngokufanele ukuze wenze ipulasitiki ngokugcwele;

④SebenzisaI-SILIEK PFAS-free PPA masterbatchingathuthukisa ngempumelelo i-resin processing fluidity, ithuthukise ukusebenza kokugcoba kwangaphakathi nangaphandle, ithuthukise ukuhlakazeka phakathi kwezingxenye, inciphise ukuhlangana, ithuthukise ukuqoqwa kokufa komlomo, futhi ngesikhathi esifanayo ingakhishwa ekhoneni elifile lemishini, ngaleyo ndlela ithuthukise. izinga eliphezulu lefilimu.I-SILIEK PFAS-free PPA masterbatchiyindlela ehlukile kunezithasiselo ze-polymer e-fluorinated PPA ukuhlangabezana nezidingo zomkhawulo wamanje we-fluorine.I-SILIEK PFAS-free PPA masterbatchithatha indawo ephelele yezithasiselo ze-fluorinated polymer PPA, ezihlangabezana nezidingo zomkhawulo wamanje we-fluorine.

⑤ Ukusetshenziswa kweUchungechunge lwe-SILIKE SILIMER lwe-ejenti yokuvula okushelelayo kwefilimu enganeli, ukuxazulula i-ejenti yendabuko ebushelelezi kulula ukuqeda inkinga yempushana.

Izixazululo zefilimu ze-LDPE zokuthuthukisa ikhwalithi yomkhiqizo

I-SILIMER Series I-Non-Precipitation Film Slip Masterbatchiwuhlobo lwe-copolysiloxane eguquliwe equkethe amaqembu asebenzayo ezinto eziphilayo athuthukiswe i-Silicone. Iketango elide lekhabhoni lihambisana ne-resin ukuze lidlale indima yokubambisa, futhi iketango le-silicon lihlukaniswa libe ngaphezulu kwefilimu ukuze lidlale indima yokushelela, engadlala indima yokushelela ngaphandle kwemvula ephelele.

Ukwengeza inani elincaneSILIKE SILIMER 5064MB1, I-SILIMER 5064MB2nolunye uchungechunge lwemikhiqizo lungathuthukisa kakhulu ikhwalithi yefilimu, ngokungafani ne-talc yefilimu yendabuko,I-SILIMER uchungechunge lwefilimu engaconsiI-talc ayidli, ayiwi ngaphandle kwempushana, i-coefficient of friction izinzile, i-talc yokushisa ephezulu ayinamatheli. Ngesikhathi esifanayo akuthinti ukucutshungulwa okulandelayo kwefilimu, akuphazamisi ukusebenza kokuvalwa kokushisa kwefilimu, akuphazamisi ukucaca kwefilimu, akuphazamisi ukuphrinta, i-laminating nokunye.
