Ukupakisha okuguquguqukayo kuyindlela yokupakisha eyenziwe ngezinto eziguquguqukayo ezihlanganisa izinzuzo zepulasitiki, ifilimu, iphepha ne-aluminium foil, enezici ezifana nesisindo esincane nokuphatheka, ukumelana okuhle namandla angaphandle, nokusimama. Ezinye zezinto ezisetshenziswa emaphaketheni aguquguqukayo ikakhulukazi ifilimu yepulasitiki, ucwecwe lwe-aluminium, izinto ezisekelwe ku-bio, izinto ezimboziwe, ukupakisha okubolayo nokunye.

Izinhlelo zokusebenza zomkhiqizo wokupakisha eziguquguqukayo zihlanganisa: izikhwama, ifilimu egoqayo, izikhwama zegrosa, ukugoqa okushwabeneyo, ifilimu enwetshiwe kanye nokupakishwa kwamanzi asebhodleleni. Izici eziyingqayizivele zale mikhiqizo ngokwamandla emishini, ukusebenza kahle kwezithiyo (isb., ukuvikela ukudla ekungcoleni), ukubekezelela ukuphrinta, ukumelana nokushisa, ukubukeka okubonakalayo (isb., ukucwebezela okuphezulu nokucaca), ukuphinda kusetshenziswe kabusha, kanye nokusebenza kahle kwezindleko yikho okwenza bagqame.

Phakathi kwazo, amafilimu epulasitiki asetshenziswa emaphaketheni aguquguqukayo ezinhlobonhlobo zezinto zokwakha, kufaka phakathi lokhu okulandelayo:

I-Polyethylene (PE): kufaka phakathi i-polyethylene ephansi (i-LDPE) kanye ne-linear low-density polyethylene (LLDPE), evame ukusetshenziswa kungqimba lwangaphakathi lwezinto zokupakisha zokudla, ezinezakhiwo ezinhle zokuvala ukushisa nokuguquguquka.

I-Polypropylene (PP): evame ukusetshenziswa ekwenzeni ifilimu, enokumelana nokushisa okuhle kakhulu nokumelana namakhemikhali, okuvame ukusetshenziswa ezintweni eziyisisekelo.

I-polyester (PET): evame ukusetshenziswa njengongqimba lwangaphandle noma oluphakathi lokupakisha ngenxa yezakhiwo zayo ezinhle zokusebenza nokungafihli lutho, okuhlinzeka ngamandla nobuhle.

Inayiloni (PA): inikeza izakhiwo ezinhle zokuvimbela futhi ivame ukusetshenziselwa ukupakisha okudinga ukusebenza kwesithiyo esiphezulu.

I-Ethylene vinyl acetate copolymer (EVA): Inikeza ukuguquguquka okuhle nokunamathela futhi kuvame ukusetshenziswa njengesendlalelo sokuvala ukushisa.

I-Polyvinylidine dichloride (PVDC): inezindawo zokuvimbela umoya ophezulu kakhulu kanye nomswakama, ezivame ukusetshenziswa emaphaketheni ezidinga ubusha besikhathi eside.

I-Ethylene Vinyl Alcohol Copolymer (EVOH): inikeza izakhiwo ezinhle kakhulu zokuvimbela umoya-mpilo njengesendlalelo sokuvimbela.

I-Polyvinyl chloride (PVC): isetshenziswa kwezinye izinhlelo zokusebenza, kodwa ukusetshenziswa kwayo kunqunyelwe ngenxa yokukhathazeka kwemvelo nempilo.

Izinto ezisekelwe ku-bio: njenge-polylactic acid (PLA), njengenye impahla evumelana nemvelo enokonakala okuhle kwe-biodegradability.

Izinto ze-Biodegradable: ziyathuthukiswa ukuze kuncishiswe umthelela wemvelo wokupakisha.

Amafilimu ayinhlanganisela anezingqimba eziningi: Izinhlanganisela zezingqimba eziningi ze-PA, EVOH, PVDC ezinezinhlaka ezifana ne-PE, EVA, PP, njll.

Lezi zinto zingasetshenziswa ngazodwana noma zihlanganiswe ukuze zenze amafilimu ayinhlanganisela ukuze ahlangabezane nezidingo ezahlukene zokupakisha ezifana nezakhiwo zokuvimbela, ukuvaleka kokushisa, amandla emishini kanye nobuhle. Emaphaketheni aguquguqukayo, lezi zinto zivame ukuhlanganiswa ngezinqubo ze-lamination noma co-extrusion ukuze zenze izinto zokupakisha ezinemisebenzi ethile.

Ungayixazulula kanjani inkinga ye-PE, PP, PET, PA nezinye izinto ekucubungulweni kwenqubo ye-extrusion ethambekele ekubeni namaphutha?

Izinto ezibalwe ngenhla, njenge-PE, PP, PET, PA, njll., zijwayele ukwakheka komlomo, amazinga okukhipha kancane kancane, ukugqabuka okuncibilika, kanye nezindawo ezingaphandle ezinokukhubazeka ngesikhathi sokucubungula nokukhishwa. Imvamisa, abakhiqizi abakhulu bazongeza izinsiza zokucubungula ze-polymer PPA e-fluorinated ukuthuthukisa ukusebenza kokucubungula. Kodwa-ke, eminyakeni yamuva, ngokuqwashisa okukhulayo kokuvikelwa kwemvelo kanye ne-Fluoride Restriction Order ehlongozwayo, ukuthola ezinye izindlela zokusebenzisa izinsiza zokucubungula i-polymer PPA ye-fluorine sekuwumsebenzi ophuthumayo.

Emhlabeni jikelele, i-PFAS isetshenziswa kabanzi emikhiqizweni eminingi yezimboni nabathengi, kodwa ingozi engaba khona emvelweni nempilo yabantu idale ukukhathazeka okusabalele. Nge-European Chemicals Agency (ECHA) yenza esidlangalaleni umkhawulo we-PFAS osalungiswa.

Ngo-2023, ithimba le-R&D le-SILIKE lisabele enkambisweni yezikhathi futhi latshala amandla amaningi ekusebenziseni izindlela zakamuva zobuchwepheshe kanye nokucabanga okusha ukuthuthukisa ngempumelelo.I-PFAS-free polymer processing aids (PPAs), okwenza umnikelo omuhle ekuvikelweni kwemvelo kanye nentuthuko esimeme. Lo mkhiqizo uqinisekisa ukusebenza kokucutshungulwa kwempahla kanye nekhwalithi ngenkathi ugwema ubungozi bemvelo nempilo obungalethwa amakhompiyutha e-PFAS endabuko.

I-SILIKE SILIMER PFAS-free PPA masterbatch iyi-PFAS-free polymer processing aid (PPA)yethulwa nguSilicone. Isengezo siyi-polysiloxane eguquliwe, esizakala ngomphumela omuhle kakhulu wokuqala wokugcoba we-polysiloxanes kanye nomthelela we-polar wamaqembu aguquliwe ukuze afuduke futhi enze izinto zokusebenza ngesikhathi sokucubungula.

SILIKE SILIMER PFAS-free PPA masterbatchkungaba indawo ephelele yezinsiza zokucubungula ze-PPA ezisekelwe ku-fluorine, ukwengeza inani elincane kungathuthukisa ngempumelelo uketshezi lwe-resin, ukucutshungulwa, kanye nezici ze-lubricity nezici zangaphezulu ze-extrusion yepulasitiki, isuse ukugqabuka kokuncibilika, ithuthukise ukumelana nokugqokwa, inciphise i-coefficient of friction. , ngcono ukukhiqizwa kanye nekhwalithi yomkhiqizo, kodwa futhi ihambisana nemvelo futhi iphephile.

SILIKE SILIMER PFAS-free PPA masterbatchinezinhlobonhlobo zezicelo, hhayi kuphela kumafilimu epulasitiki, kodwa futhi nezintambo nezintambo, amashubhu, ama-masterbatches ombala, imboni ye-petrochemical nokunye.

Uma usembonini yokupakisha eguquguqukayo futhi ufuna ukuthuthukisa ukuncintisana kwemikhiqizo yakho, ungasebenzisaIzithasiselo ze-PPA zamahhala zika-SILIKE ze-PFAS.
