Izidingo zansuku zonke ezifana nokudla nezinto zasendlini zibalulekile ekuphileni kwansuku zonke kwabantu. Njengoba ukuphila kuqhubeka ngesivinini, ukudla okupakishiwe okuhlukahlukene kanye nezidingo zansuku zonke kuye kwagcwalisa izitolo ezinkulu nezitolo ezinkulu, okwenza kube lula ngabantu ukuba bazithenge, bazigcine futhi bazisebenzise lezi zinto. Izinto zokupakisha zidlala indima ebalulekile kulokhu kuba lula. Ngokuthuthuka okuqhubekayo kwemboni yokupakisha, imigqa yokukhiqiza ukupakisha okuzenzakalelayo iya ngokuya isetshenziswa ekukhiqizeni ukudla kanye nezidingo zansuku zonke. Njengoba isivinini kanye nokuzenzakalelayo kwemishini yokupakisha kuqhubeka nokwanda, izindaba zekhwalithi nazo sezigqamile. Izinkinga ezinjengokuphuka kwefilimu, ukushelela, ukuphazamiseka kolayini wokukhiqiza, nokuvuza kwamaphakheji ziya ziba njalo, okubangela ukulahlekelwa okukhulu kubakhiqizi bezinto zokupakisha eziguquguqukayo nezinkampani zokunyathelisa. Isizathu esiyinhloko sisekungakwazini ukulawula ukungqubuzana nokushisa izici zokuvalwa kwamafilimu okupakisha okuzenzakalelayo.
Njengamanje, amafilimu okupakisha okuzenzakalelayo emakethe anamaphutha amakhulu alandelayo:
- Isendlalelo sangaphandle sefilimu yokupakisha sine-coefficient ephansi yokungqubuzana (i-COF), kuyilapho ungqimba lwangaphakathi lune-COF ephezulu, okubangela ukushelela phakathi nefilimu esebenza kulayini wokupakisha.
- Ifilimu yokupakisha yenza kahle emazingeni okushisa aphansi kodwa ihlangabezana nezinkinga emazingeni okushisa aphezulu phakathi nenqubo yokupakisha okuzenzakalelayo.
- I-COF ephansi yesendlalelo sangaphakathi ivimbela ukuma okufanele kokuqukethwe ngaphakathi kwefilimu yokupakisha, okuholela ekuhlulekeni kokuvala lapho umugqa wokuvala ukushisa ucindezela okuqukethwe.
- Ifilimu yokupakisha yenza kahle ngesivinini esiphansi kodwa ihlangabezana nezinkinga zokuvaleka kahle kokushisa kanye nezinkinga zokuvuza njengoba isivinini somugqa wokupakisha sikhula.
Ingabe uyayiqondaI-COFyefilimu yokupakisha okuzenzakalelayo? Okuvamileama-anti-blocking kanye nama-slip agentsnezinselele
I-COF ikala izici zokushelela zezinto zokupakisha. Ubushelelezi befilimu kanye ne-COF efanele kubalulekile enqubweni yokupakishwa kwefilimu, ngemikhiqizo ehlukahlukene yokupakisha enezidingo ezihlukile ze-COF. Ezinqubweni zangempela zokupakisha, ukungqubuzana kungasebenza njengokubili amandla okushayela kanye nokumelana, okudinga ukulawulwa okusebenzayo kwe-COF ngaphakathi kwebanga elifanele. Ngokuvamile, amafilimu okupakisha okuzenzakalelayo adinga i-COF ephansi uma kuqhathaniswa nesendlalelo sangaphakathi kanye ne-COF emaphakathi yongqimba lwangaphandle. Uma ungqimba lwangaphakathi lwe-COF luphansi kakhulu, lungabangela ukungazinzi nokungahambi kahle ngesikhathi sokwakhiwa kwesikhwama. Ngokuphambene, uma ungqimba lwangaphandle lwe-COF luphakeme kakhulu, lungabangela ukumelana ngokweqile ngesikhathi sokupakishwa, okuholela ekushintshashintsheni kwezinto ezibonakalayo, kuyilapho i-COF ephansi kakhulu ingabangela ukushelela, kubangele ukulandelelwa nokusika amaphutha.
I-COF yamafilimu ayinhlanganisela ithonywa okuqukethwe kwe-anti-blocking kanye nama-ejenti ashelelayo kungqimba yangaphakathi, kanye nokuqina nokushelela kwefilimu. Njengamanje, ama-slip agent asetshenziswa ezendlaleloni zangaphakathi ngokuvamile ama-fatty acid amide compounds (njengama-amide ayinhloko, ama-amide esibili, nama-bisamide). Lezi zinto azincibiliki ngokuphelele kuma-polymers futhi zivame ukuthuthela endaweni yefilimu, kunciphisa ukungqubuzana kwendawo. Kodwa-ke, ukufuduka kwama-amide slip agents kumafilimu e-polymer kuthintwa yizici ezihlukahlukene, okuhlanganisa ukugxilwa kwe-ejenti eshelelayo, ukushuba kwefilimu, uhlobo lwe-resin, ukungezwani okuguqukayo, indawo yokugcina indawo, ukucubungula phansi komfula, izimo zokusetshenziswa, nezinye izithasiselo, okwenza kube nzima ukuqinisekisa ukuzinza. I-COF. Ngaphezu kwalokho, njengoba ama-polymers engeziwe ecutshungulwa emazingeni okushisa aphezulu, ukuzinza kwe-thermal oxidative yama-slip agents kuya ngokuya kubaluleke kakhulu. Ukuwohloka kwe-oxidative kungaholela ekulahlekelweni kokusebenza kwe-ejenti eshelelayo, ukushintsha kombala, kanye nephunga.
Ama-ejenti okushelela avame kakhulu asetshenziswa kuma-polyolefin ama-amide anamafutha e-long-chain, ukusuka ku-oleamide kuye ku-erucamide. Ukusebenza kwama-slip agents kungenxa yekhono lawo lokungena endaweni yefilimu ngemuva kokukhishwa. Ama-ejenti ama-slip ahlukene abonisa amanani ahlukene emvula engaphezulu kanye nokwehliswa kwe-COF. Njengoba ama-amide slip ejenti ama-ejenti ashelelayo anesisindo esiphansi se-molecular-weight, ukufuduka kwawo ngaphakathi kwefilimu kuthonywa izici ezihlukahlukene, okuholela ku-COF engazinzile. Ezinqubweni ze-lamination ezingenakuncibilika, ama-amide slip agents amaningi efilimini angabangela izinkinga zokusebenza kokuvala ukushisa, okuvame ukubizwa ngokuthi "ukuvimbela." Lo mshini uhlanganisa ukufuduka kwama-isocyanate monomers amahhala endaweni enamathelayo endaweni yefilimu, esabela nge-amide ukuze akhe i-urea. Ngenxa yezinga eliphezulu lokuncibilika kwe-urea, lokhu kubangela ukunciphisa ukusebenza kokuvalwa kokushisa kwefilimu elaminate.
Ni-ovel isiliphu esikhulu esingafuduki&Anti-blockingumenzeli
Ukubhekana nalezi zinkinga, i-SILIKE yethuliwe I-Super-slip engancibiliki kanye ne-Anti-blocking Masterbatch Additive– ingxenye yochungechunge lwe-SILIMER. Le mikhiqizo eguquliwe ye-polysiloxane iqukethe amaqembu asebenzayo ezinto eziphilayo. Ama-molecule awo ahlanganisa kokubili izingxenye zamaketanga e-polysiloxane namaketanga ekhabhoni amade anamaqembu asebenzayo. Amaketanga ekhabhoni amade amaqembu asebenzayo angakwazi ukuhlangana ngokomzimba noma ngokwekhemikhali ne-base resin, aqinise ama-molecule futhi afinyelele ukufuduka kalula ngaphandle kwemvula. Izingxenye zamaketango e-polysiloxane endaweni zinikeza umphumela wokushelela.
Ngokuqondile,I-SILIMER 5065HByakhelwe amafilimu e-CPP, futhiI-SILIMER 5064MB1ilungele amafilimu aphehlwa nge-PE nezikhwama zokupakisha eziyinhlanganisela. Izinzuzo zale mikhiqizo zihlanganisa:
- I-SILIMER 5065HBfuthiI-SILIMER 5064MB1nikeza okuhle kakhulu kokuvinjwa nokushelela, okuholela ku-COF ephansi.
- I-SILIMER 5065HBfuthiI-SILIMER 5064MB1hlinzeka ngokusebenza kokushelela okuzinzile nokuhlala unomphela ngokuhamba kwesikhathi nangaphansi kwezimo zezinga lokushisa eliphezulu, ngaphandle kokuthinta ukuphrinta, ukuvalwa kokushisa, ukudlulisa, noma inkungu.
- I-SILIMER 5065HBfuthiI-SILIMER 5064MB1ukuqeda imvula emhlophe, iqinisekisa ubuqotho kanye nobuhle bephakheji.
Uchungechunge lwe-ejenti yesiliphu ye-SILIKE's SILIMER non-Bloominghlinzeka ngesixazululo esihle kakhulu sokulawula i-COF yamafilimu okupakisha okuzenzakalelayo, kusukela ku-Cast Polypropylene Films, amafilimu aqhunyiswe nge-PE kuya kumafilimu ahlukahlukene asebenzayo ayinhlanganisela eminingi. Ngokubhekana nezinkinga zokufuduka kwama-ejenti ayisiliphu wendabuko kanye nokuthuthukisa kakhulu ukusebenza nokubukeka kwamafilimu okupakisha, i-SILIKE inikeza ukukhetha okuthembekile kubakhiqizi bezinto zokupakisha eziguquguqukayo nezinkampani zokunyathelisa.
