Ukupakisha okuguquguqukayo kuyindlela yokupakisha eyenziwe ngezinto eziguquguqukayo ezihlanganisa izinzuzo zepulasitiki, ifilimu, iphepha kanye ne-aluminium foil, enezici ezifana nokukhanya okulula nokuphathekayo, ukumelana okuhle namandla angaphandle, kanye nokusimama. Ezinye zezinto ezisetshenziswa ekupakisheni okuguquguqukayo ikakhulukazi ifilimu yepulasitiki, i-aluminium foil, izinto ezisekelwe ku-bio, izinto ezimboziwe, ukupakisha okubolayo nokunye.

Izicelo zomkhiqizo wokupakisha eziguquguqukayo zifaka: izikhwama, ifilimu yokugoqa, izikhwama zokudla, i-shrink wrap, ifilimu yokunwebeka kanye nokupakisha amanzi asemabhodleleni. Izakhiwo ezihlukile zale mikhiqizo maqondana namandla omshini, ukusebenza kahle kwezithiyo (isb., ukuvikelwa kokudla ekungcoleni), ukubekezelela ukuphrinta, ukumelana nokushisa, ukubukeka okubonakalayo (isb., ukukhanya okuphezulu nokucacile), ukuphinde kusetshenziswe, kanye nokusebenza kahle kwezindleko yikona okuyenza ivelele.

Phakathi kwazo, amafilimu epulasitiki asetshenziswa ekupakisheni okuguquguqukayo ezintweni ezahlukahlukene kakhulu, okuhlanganisa okulandelayo:

I-Polyethylene (PE): kufaka phakathi i-polyethylene ephansi (LDPE) kanye ne-polyethylene ephansi (LLDPE) eqondile, evame ukusetshenziswa engxenyeni yangaphakathi yezinto zokupakisha ukudla, enezakhiwo ezinhle zokuvala ukushisa kanye nokuguquguquka.

I-Polypropylene (PP): ivame ukusetshenziswa ekwenziweni kwefilimu, inokumelana okuhle kakhulu nokushisa kanye nokumelana namakhemikhali, ivame ukusetshenziswa ezintweni eziyisisekelo.

I-Polyester (i-PET): ivame ukusetshenziswa njengengqimba yangaphandle noma ephakathi yokupakisha ngenxa yezakhiwo zayo ezinhle zomshini kanye nokucaca, okunikeza amandla kanye nobuhle.

Inayiloni (PA): inikeza izakhiwo ezinhle zokuvimba futhi ivame ukusetshenziselwa ukupakisha okudinga ukusebenza okuphezulu kokuvimba.

I-ethylene vinyl acetate copolymer (i-EVA): Inikeza ukuguquguquka okuhle nokunamathela futhi ivame ukusetshenziswa njengesendlalelo sokuvala ukushisa.

I-Polyvinylidene dichloride (PVDC): inezakhiwo zokuvimba umoya nomswakama eziphezulu kakhulu, ezivame ukusetshenziswa ekupakisheni okudinga ukusha kwesikhathi eside.

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

I-Polyvinyl chloride (i-PVC): isetshenziswa kwezinye izinhlelo zokusebenza, kodwa ukusetshenziswa kwayo kunqunyelwe ngenxa yezinkinga zemvelo nezempilo.

Izinto ezisekelwe ku-bio: njenge-polylactic acid (PLA), njengenye into enobungani nemvelo futhi enokubola okuhle.

Izinto ezibolayo: ziyathuthukiswa ukuze kuncishiswe umthelela wokupakisha emvelweni.

Amafilimu ahlanganisiwe ahlanganisiwe anezingqimba eziningi: Inhlanganisela ye-PA, EVOH, PVDC enezingqimba eziningi nama-resin afana ne-PE, i-EVA, i-PP, njll. ukuhlinzeka ngezakhiwo ezivimbe kakhulu.

Lezi zinto zingasetshenziswa ngazinye noma zihlanganiswe ukwakha amafilimu ahlanganisiwe ukuze kuhlangatshezwane nezidingo ezahlukene zokupakisha njengezakhiwo zokuvimbela, ukuvalwa kokushisa, amandla omshini kanye nobuhle. Ekupakisheni okuguquguqukayo, lezi zinto zivame ukuhlanganiswa ngezinqubo zokubopha noma zokuhlanganisa ukuze kwakhiwe izinto zokupakisha ezinemisebenzi ethile.

Indlela yokuxazulula inkinga ye-PE, i-PP, i-PET, i-PA nezinye izinto ekucutshungulweni kwenqubo yokukhipha izinto ezithambekele ekuphazamisekeni?

Izinto ezingenhla, njenge-PE, i-PP, i-PET, i-PA, njll., zivame ukwakheka komlomo omile, amazinga okukhipha ahamba kancane, ukuqhekeka kokuncibilika, kanye nezindawo ezikhishwe ezinawo amaphutha ngesikhathi sokucubungula nokukhipha. Ngokuvamile, abakhiqizi abakhulu bazofaka izinsiza zokucubungula i-polymer PPA ene-fluorinated ukuze bathuthukise ukusebenza kokucubungula. Kodwa-ke, eminyakeni yamuva nje, ngokuqwashisa okwandayo ngokuvikelwa kwemvelo kanye ne-Fluoride Restriction Order ehlongozwayo, ukuthola ezinye izindlela zokusebenzisa izinsiza zokucubungula i-polymer PPA ene-fluorinated sekuyinselele enkulu.

Emhlabeni jikelele, i-PFAS isetshenziswa kabanzi emikhiqizweni eminingi yezimboni kanye neyabathengi, kodwa ingozi yayo engaba khona emvelweni nasempilweni yabantu ibangele ukukhathazeka okukhulu. Njengoba i-European Chemicals Agency (ECHA) imemezela umphakathi umkhawulo we-PFAS.

Ngo-2023, ithimba le-R&D le-SILIKE liphendule ekuthambekeni kwezikhathi futhi latshala amandla amaningi ekusebenziseni izindlela zobuchwepheshe zakamuva kanye nokucabanga okusha ukuze lithuthuke ngempumelelo.Izinsiza zokucubungula i-polymer ezingenayo i-PFAS (ama-PPA), okwenza umnikelo omuhle ekuvikelweni kwemvelo kanye nentuthuko esimeme. Lo mkhiqizo uqinisekisa ukusebenza kahle kokucubungula izinto kanye nekhwalithi ngenkathi ugwema izingozi zemvelo nezempilo ezingalethwa yizakhi zendabuko ze-PFAS.

I-SILIKE SILIMER PPA-free PPAS masterbatch iyi-PFAS-free polymer processing aid (PPA)kwethulwa yiSilicone. Isithasiselo siyi-polysiloxane eguquliwe ngokwemvelo, esebenzisa umphumela omuhle kakhulu wokuthambisa wokuqala wama-polysiloxane kanye nomphumela we-polar wamaqembu aguquliwe ukuze athuthe futhi asebenze emishinini yokucubungula ngesikhathi sokucubungula.

SILIKE SILIMER PFAS-free PPA masterbatchkungaba yindawo efanele yokufaka izinsiza zokucubungula ze-PPA ezisekelwe ku-fluorine, ukwengeza inani elincane kungathuthukisa ngempumelelo ukugeleza kwe-resin, ukucutshungulwa, kanye nokuthamba kanye nezici zobuso be-extrusion yepulasitiki, kuqede ukuqhekeka kokuncibilika, kuthuthukise ukumelana nokuguguleka, kunciphise i-coefficient yokungqubuzana, kuthuthukise ukukhiqizwa kanye nekhwalithi yomkhiqizo, kodwa futhi kunobungani nemvelo futhi kuphephile.

SILIKE SILIMER PFAS-free PPA masterbatchinezinhlelo zokusebenza eziningi ezahlukene, hhayi nje kuphela zamafilimu epulasitiki, kodwa futhi nezintambo nezintambo, amashubhu, ama-masterbatches ombala, imboni ye-petrochemical njalo njalo.

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