Ifilimu yePlastiki iwuhlobo lomkhiqizo wepulasitiki osetshenziswa kabanzi ekufakweni, ezolimo, ezokwakha, nakweminye imikhakha. Ayisindi, iyaguquguquka, isobala, ayizwani namanzi, ayizwani ne-asidi ne-alkali, futhi inobufakazi obuhle bomswakama, ivikela uthuli, igcina ubusha, ifaka ukushisa, neminye imisebenzi. Njengamanje, amafilimu epulasitiki ajwayelekile emakethe ikakhulukazi i-polyethylene (PE), i-polypropylene (PP), i-polyvinyl chloride (PVC), njalonjalo.

Ifilimu ye-Polythene ingenye yamafilimu epulasitiki asetshenziswa kakhulu emakethe namuhla. Ibonakala ngokuguquguquka okuhle, ukucaca okuphezulu, nokumelana nokugqwala okuphezulu.

Ngokuhambisana nokuminyana okuhlukene kwe-polyethylene, ifilimu ye-polyethylene iphinde ihlukaniswe ibe yifilimu ye-polyethylene ephezulu (HDPE) kanye nefilimu ye-polyethylene ephansi (LDPE). Ifilimu ye-HDPE inamandla amakhulu nobulukhuni, futhi ifanele izinto zokupakisha kanye nefilimu yokumboza ngezolimo kanye neminye imikhakha; Ifilimu ye-LDPE iyavumelana nezimo futhi ilungele ukupakishwa kokudla kanye nezikhwama zikadoti nezinye izinkambu.

Inqubo yokukhiqiza ifilimu ye-polyethylene ikakhulukazi ihlanganisa indlela ye-extrusion kanye nendlela yefilimu eshaywayo. Ngokuya ngamasu ahlukene okucubungula ifilimu, ingahlukaniswa ngezinhlobo ezimbalwa, njengefilimu eshaywayo (i-IPE), ifilimu yabalingisi (CPE), nefilimu enegwebu eliphansi.

Amandla aqinile wefilimu ye-PE nokuvuleka kungcono kunefilimu ye-CPE, esebenzisa ukuphrinta kwangaphambili, ingasetshenziselwa izikhwama zokudla, izikhwama zezingubo, njll; Ukufana kwefilimu ye-CPE, isicwebezelisi esicwebezelayo, ukukhanya, nokubekwa uphawu kokushisa kune-PE kungcono, kungaphrintwa ngaphambili nangemuva, kodwa izindleko zokukhiqiza ziphezulu. Ifilimu ye-CPE isetshenziswa kakhulu njengesikhwama esiyinhlanganisela sesendlalelo sangaphakathi, kanye nezimonyo, amasoso, namakhekhe okupakisha; ifilimu enegwebu eliphansi ihlobisa, iwugqinsi, akulula ukwelula nokukhubazeka, isebenzisa ukunyathelisa kwangaphambili, okusetshenziselwa imidwebo kaNcibijane, izimpawu zokuthengisa nezikhwama zezandla. Ifilimu enegwebu eliphansi ilungele ukuhlobisa, ukuthungwa okuminyene, akulula ukwelula nokonakala, futhi iphrintiwe ohlangothini olungaphambili, futhi isetshenziswa emidwebeni kaNcibijane, izimpawu zokuthengisa, nezikhwama zezandla.

Ifilimu ye-PE emkhakheni wokupakisha iyona esetshenziswa kakhulu futhi ingasetshenziselwa ukupakisha ukudla, ukupakishwa komkhiqizo kagesi, ukupakishwa kwezidingo zansuku zonke, ukupakisha izingubo, njalonjalo. Banephuzu elivamile, okungukuthi, ifilimu yepulasitiki iwukunyathelisa umbala, njengokupakisha ukudla kodwa futhi ihlanganisa izingqimba eziningi kanye neminye imisebenzi yenqubo.

Kodwa-ke, ifilimu ye-PE ijwayele izindawo ze-crystal, futhi i-white powder precipitates ibilokhu iyinkinga ye-clichéd, evame kakhulu ekukhiqizweni kwefilimu, kodwa futhi ikhanda elibuhlungu kakhulu. Abakhiqizi abaningi bamafilimu baye bathinteka ngenxa yemvula yefilimu ethinta ukuphrinta okulandelayo, kanye nekhwalithi yomkhiqizo wokugcina.

Nakuba izinkinga ze-crystal point zivamile, akulula ukuzixazulula. Lokhu kungenxa yokuthi kunezici eziningi ezingabangela izinkinga ze-crystal point. Uma imbangela ye-crystal pitting ingacacile, kunzima ukuthatha izinyathelo zokuyithuthukisa noma ukuyixazulula. Ngakho-ke, okokuqala kudingeka siqonde izimbangela crystal pitting, okubangelwa izimo ezinhlanu ezilandelayo:

• Ukungcola kwangaphandle
• I-plasticization engalungile
• Ukuxhumanisa ngemva kokuguga/i-oxidation
• I-Carbonisation yezinto ngesikhathi sokucutshungulwa, okuholela “ekugcineni kwekhabhoni esikhunjeni somlomo”.
• Imvula eyengeziwe, njll.

Ama-slip agents amafilimu e-PE ngokuvamile ayi-oleic acid amide noma i-erucic acid amide, futhi umsebenzi we-toning udinga ukuthi anciphe phezu kwefilimu, ngaphandle kwalokho ngeke kube khona ukushelela. I-ejenti ebushelelezi ngoba yengeziwe, ayixhunyelelwanga ku-molecule ye-PE, ukucubungula ifilimu, ngokuhamba kwesikhathi nezinga lokushisa, i-ejenti ebushelelezi izosuka kungqimba lwefilimu yolwelwesi lwangaphakathi iye ekufudukeni kwangaphandle. Ukuqaphela ngokucophelela kuzotholakala kuwungqimba oluncane kakhulu lwempushana noma impahla efana ne-wax, isikhathi eside, ukufuduka okwengeziwe. Uma imvula ye-ejenti ebushelelezi ibucayi kakhulu, ayithinti kuphela umsebenzi wemishini yokupakisha ezenzakalelayo, kodwa futhi ithinta ukufaneleka kokuphrinta, amandla ayinhlanganisela, kanye nokungcoliswa kwempahla epakishiwe.

Ukuguqula isiko, ukucwaninga, nokusungula izinto ezintshaUchungechunge lwe-SILIKE SILIMER Isithasiselo Sesilayidi Esingapheli EsingafudukiI-Flexible Packaging ixazulula ngokuphelele inkinga ye-precipitates emhlophe, Ngesikhathi esifanayo, lokhuI-ejenti yokushelela ekungeyona imvulaingasiza futhi abakhiqizi befilimu ye-PE ekuxazululeni izinkinga ze-crystallization point ngesikhathi sokukhiqiza.

Ithimba elizinikele le-R&D lika-SILIKE libhekane ngempumelelo nalezi zinkinga ngokwakhiwa kwesisekeloI-non-Blooming Super-slip & anti-blocking Masterbatch Additives – ingxenye yochungechunge lwe-SILIMER, okuxazulula ngempumelelo ukushiyeka kwe-ejenti yendabuko yokushelela, Engafuduki kuzo zonke izendlalelo zefilimu, iqinisekisa ukusebenza kokushelela okuzinzile nokuhlala isikhathi eside, okuletha ubuhlakani obusha embonini ye-Plastic Film Flexible Packaging Industry. Lokhu kuphumelela kunikeza izinzuzo ezinjengokuthonya okuncane ekuphrinteni, ukuvala ukushisa, ukudlulisa, noma inkungu, kanye ne-CoF encishisiwe, ukuvimbela okuhle, nokushelela okuthuthukisiwe kwendawo, okuqeda imvula emhlophe.

I-SILIMER uchungechunge lwe-Super-slip engancibiliki futhi olwa nokuvinjwa kwe-Masterbatch Additivesinezinhlobonhlobo zezinhlelo zokusebenza futhi ingasetshenziswa ekukhiqizweni kwamafilimu e-BOPP/CPP/PE/TPU/EVA, njll.

Izinzuzo zeUchungechunge lwe-SILIKE SILIMER Izithasiselo ze-Masterbatch ezingancibiliki futhi ezingavimbeli:

1.Idatha yokuhlola ibonisa ukuthi amanani amancane weSILIKE SILIMER 5064MB1, futhiSILIKE SILIMER 5065HBinganciphisa ngempumelelo i-coefficient of friction futhi ibe nokushelela okuhlala isikhathi eside nokuzinzile kungakhathaliseki isimo sezulu kanye nezinga lokushisa;

2.Ukwengezwa kweSILIKE SILIMER 5064MB1, futhiSILIKE SILIMER 5065HBngesikhathi sokulungiswa kwamafilimu epulasitiki akuthinti ukucaca kwefilimu futhi ayithinti inqubo yokuphrinta elandelayo;

3.UkwengezaSILIKE SILIMER 5064MB1, futhiSILIKE SILIMER 5065HBngamanani amancane ixazulula inkinga ukuthi ama-amide slip agents ajwayelekile atholakala kalula noma abe yimpushana, athuthukisa ikhwalithi yomkhiqizo, futhi onge izindleko eziphelele.

Ingabe uyafuna ukufaka esikhundleni sama-amide slip agents asezandleni zakho? Uyafuna ukufaka i-ejenti yakho ye-amide slip yefilimu yePlastiki, noma ufuna ukusebenzisa i-ejenti yesiliphu esizinzile futhi esebenza ngempumelelo yokuvikela imvelo ye-Plastic Film, i-SILIKE iyakwamukela ukuthi usithinte noma kunini, futhi sibheke ngabomvu ukudala okwengeziwe amathuba kanye nawe!
