Izindaba

Izinto ezidingekayo nsuku zonke njengokudla nezinto zasekhaya zibalulekile empilweni yabantu yansuku zonke. Njengoba ijubane lempilo liqhubeka nokusheshisa, ukudla okuhlukahlukene okupakishiwe kanye nezinto ezidingekayo zansuku zonke kuye kwagcwalisa izitolo ezinkulu kanye nezitolo ezinkulu, okwenza kube lula ngabantu ukuthenga, ukugcina, nokusebenzisa lezi zinto. Izinto zokupakisha zidlala indima ebalulekile kulokhu kulula. Ngokuthuthuka okuqhubekayo kwemboni yokupakisha, imigqa yokukhiqiza ukupakisha okuzenzakalelayo isetshenziswa kakhulu ekukhiqizeni ukudla nezidingo zansuku zonke. Njengoba ijubane kanye nokuzenzakalela kwemishini yokupakisha kuqhubeka nokukhula, izinkinga zekhwalithi nazo ziye zabonakala. Izinkinga ezifana nokuphuka kwefilimu, ukushelela, ukuphazamiseka kwemigqa yokukhiqiza, kanye nokuvuza kwamaphakheji kuya ngokuya kwenzeka, okubangela ukulahlekelwa okukhulu kubakhiqizi abaningi bezinto zokupakisha eziguquguqukayo kanye nezinkampani zokunyathelisa. Isizathu esiyinhloko sisekungakwazi ukulawula ukungqubuzana kanye nezakhiwo zokuvala ukushisa zamafilimu okupakisha okuzenzakalelayo.

Njengamanje, amafilimu okupakisha okuzenzakalelayo emakethe anezinkinga ezilandelayo eziyinhloko:

1. Ingqimba yangaphandle yefilimu yokupakisha ine-coefficient ephansi yokungqubuzana (i-COF), kuyilapho ingqimba yangaphakathi ine-COF ephezulu, okubangela ukushelela ngesikhathi ifilimu isebenza emgqeni wokupakisha.
2. Ifilimu yokufaka isebenza kahle emazingeni okushisa aphansi kodwa ihlangabezana nezinkinga emazingeni okushisa aphezulu ngesikhathi senqubo yokufaka ezenzakalelayo.
3. I-COF ephansi yesendlalelo sangaphakathi ivimbela ukufakwa okufanele kokuqukethwe ngaphakathi kwefilimu yokupakisha, okuholela ekungasebenzi kahle kokuvala lapho umugqa wokuvala ukushisa ucindezela okuqukethwe.
4. Ifilimu yokufaka isebenza kahle ngesivinini esiphansi kodwa ihlangabezana nezinkinga zokuvala ukushisa kanye nokuvuza okubi njengoba isivinini somugqa wokupakisha sanda.

Uyakuqonda yiniI-COFyefilimu yokupakisha ezenzakalelayoOkuvamileama-anti-blocking kanye nama-slip agentskanye nezinselele

I-COF ilinganisa izici zokushelela zezinto zokupakisha. Ukushelela kobuso befilimu kanye ne-COF efanele kubalulekile enqubweni yokupakisha ifilimu, ngemikhiqizo ehlukene yezinto zokupakisha enezidingo ze-COF ezihlukene. Ezinqubweni zangempela zokupakisha, ukungqubuzana kungasebenza njengamandla okushayela kanye nokumelana, okudinga ukulawulwa okusebenzayo kwe-COF ngaphakathi kobubanzi obufanele. Ngokuvamile, amafilimu okupakisha okuzenzakalelayo adinga i-COF ephansi kakhulu yesendlalelo sangaphakathi kanye ne-COF emaphakathi yesendlalelo sangaphandle. Uma isendlalelo sangaphakathi se-COF siphansi kakhulu, singase sibangele ukungazinzi kanye nokungahambi kahle ngesikhathi sokwakheka kwesikhwama. Ngokuphambene nalokho, uma isendlalelo sangaphandle se-COF siphezulu kakhulu, singase sibangele ukumelana okukhulu ngesikhathi sokupakisha, okuholela ekuguqukeni kwezinto, kuyilapho i-COF ephansi kakhulu ingaholela ekusheleleni, okubangela ukulandelela nokusika ukungalungi.

I-COF yamafilimu ahlanganisiwe ithonywa okuqukethwe ama-anti-blocking kanye nama-slip agents engqimbeni yangaphakathi, kanye nokuqina kanye nokushelela kwefilimu. Njengamanje, ama-slip agents asetshenziswa ezingqimbeni zangaphakathi ngokuvamile angama-fatty acid amide compounds (njenge-primary amides, i-secondary amides, kanye ne-bisamides). Lezi zinto azincibiliki ngokuphelele kuma-polymers futhi zivame ukuthuthela ebusweni befilimu, okunciphisa ukungqubuzana kobuso. Kodwa-ke, ukufuduka kwama-amide slip agents kumafilimu e-polymer kuthinteka yizici ezahlukahlukene, okuhlanganisa ukuhlushwa kwe-slip agent, ukujiya kwefilimu, uhlobo lwe-resin, ukungezwani kokujikeleza, indawo yokugcina, ukucubungula phansi, izimo zokusetshenziswa, nezinye izithasiselo, okwenza kube nzima ukuqinisekisa i-COF ezinzile. Ngaphezu kwalokho, njengoba ama-polymer amaningi ecutshungulwa emazingeni okushisa aphezulu, ukuzinza kwe-oxidative kwe-thermal kwama-slip agents kuba kubaluleke kakhulu. Ukuwohloka kwe-oxidative kungaholela ekulahlekelweni kokusebenza kwe-slip agent, ukushintsha kombala, kanye nephunga.

Ama-slip agent avame kakhulu asetshenziswa kuma-polyolefin yi-long-chain fatty acid amides, kusukela ku-oleamide kuya ku-erucamide. Ukusebenza kahle kwama-slip agent kungenxa yekhono lawo lokufika ebusweni befilimu ngemva kokukhipha. Ama-slip agent ahlukene abonisa amazinga ahlukene okuna kwezulu kanye nokunciphisa i-COF. Njengoba ama-amide slip agents eyizithutha ezifudukayo ezinesisindo esiphansi sama-molecule, ukufuduka kwawo ngaphakathi kwefilimu kuthonywa yizici ezahlukahlukene, okuholela ku-COF engazinzile. Ezinqubweni ze-lamination ezingenasombululo, ama-amide slip agents amaningi efilimu angabangela izinkinga zokusebenza kokuvala ukushisa, okuvame ukubizwa ngokuthi "ukuvimba." Indlela ihilela ukufuduka kwama-monomers e-isocyanate yamahhala ku-adhesive kuya ebusweni befilimu, asabela ne-amide ukuze akhe i-urea. Ngenxa yezinga eliphezulu lokuncibilika kwe-urea, lokhu kuphumela ekusebenzeni okuncishisiwe kokuvala ukushisa kwefilimu elaminethiwe.

Ni-ovel ukushelela okukhulu okungafuduki&Ukulwa nokuvinjelwai-ejenti

Ukuze kuxazululwe lezi zinkinga, i-SILIKE yethule uhlelo lwe- I-Super-slip engangenisi amanzi kanye ne-Anti-blocking Masterbatch Additive– ingxenye yochungechunge lwe-SILIMER. Le mikhiqizo ye-polysiloxane eguquliwe iqukethe amaqembu asebenzayo e-organic. Ama-molecule awo afaka phakathi izingxenye ze-polysiloxane chain kanye nezintambo ze-carbon ezinde ezinamaqembu asebenzayo. Izintambo ze-carbon ezinde zamaqembu asebenzayo asebenzayo zingahlangana ngokomzimba noma ngamakhemikhali ne-base resin, ziqinise ama-molecule futhi zenze ukufuduka kalula ngaphandle kwemvula. Izingxenye zezintambo ze-polysiloxane ebusweni zinikeza umphumela wokushelela.

Ngokuqondile,I-SILIMER 5065HByenzelwe amafilimu e-CPP, futhiI-SILIMER 5064MB1ifanele amafilimu afakwe i-PE kanye nezikhwama zokupakisha ezihlanganisiwe. Izinzuzo zale mikhiqizo zifaka:

• I-SILIMER 5065HBfuthiI-SILIMER 5064MB1inikeza ukuvikela okuhle kakhulu ekuvimbeni nasekubusheleleni, okuholela ekutheni i-COF ibe phansi.
• I-SILIMER 5065HBfuthiI-SILIMER 5064MB1ihlinzeka ngokusebenza okuzinzile nokuhlala njalo kokushelela ngokuhamba kwesikhathi nangaphansi kwezimo zokushisa okuphezulu, ngaphandle kokuthinta ukuphrinta, ukuvala ukushisa, ukudlulisa, noma umswakama.
• I-SILIMER 5065HBfuthiI-SILIMER 5064MB1qeda ukuna kwempuphu emhlophe, ukuqinisekisa ubuqotho kanye nobuhle bephakheji.

Uchungechunge lwe-SILIKE's SILIMER non-Blooming slip agentihlinzeka ngesisombululo esihle kakhulu sokulawula i-COF yamafilimu okupakisha okuzenzakalelayo, kusukela ku-Cast Polypropylene Films, amafilimu e-PE-blown kuya kumafilimu ahlukahlukene asebenzayo ahlanganisiwe. Ngokubhekana nezinkinga zokufuduka kwama-slip agents endabuko kanye nokuthuthukisa kakhulu ukusebenza kanye nokubukeka kwamafilimu okupakisha, i-SILIKE inikeza ukukhetha okuthembekile kwabakhiqizi bezinto zokupakisha eziguquguqukayo kanye nezinkampani zokunyathelisa.
