Izinto Zokuhlola Ezivamile kanye Nezindinganiso Zepharamitha zeIfilimu Yokuvikela Upende we-TPU (PPF)Imikhiqizo, kanye Nendlela Yokuqinisekisa Ukuthi Lezi Zinto Ziyadlula Ngesikhathi Sokukhiqiza
Isingeniso
Ifilimu Yokuvikela Upende we-TPU (i-PPF) iyifilimu esobala esebenza kahle esetshenziswa ezindaweni zopende zezimoto ukuvikela ezitsheni zamatshe, imihuzuko, imvula ene-asidi, imisebe ye-UV, kanye neminye imonakalo. Isethi eqinile yezindinganiso zokuhlola ikhwalithi kanye nohlelo lokulawula inqubo yokukhiqiza oluhambisanayo kubalulekile ukuqinisekisa ukusebenza kwayo okumangalisayo kanye namakhono okuvikela ahlala isikhathi eside.
1. Izinto Zokuhlola Ezivamile kanye Nezidingo Ezijwayelekile Zepharamitha
Ithebula elingezansi lifingqa izinto zokuhlola eziyinhloko kanye nezindinganiso ezijwayelekile zamapharamitha ezisezingeni eliphezuluI-PPFimikhiqizo kufanele ihlangane.

Ukuhunyushwa Kwepharamitha Eyinhloko:
- Umswakama ≤ 1.5%: Kuqinisekisa ukuthi ifilimu ayithinti ukucaca kokuqala kanye nomphumela wokubonakala kopende ngemva kokusetshenziswa.
- Inkomba Yokuphuzi ≤ 1.5: Iqinisekisa ukuthi ifilimu ngokwayo ayiphuzi futhi inekhono elihle kakhulu lokulwa nokuphuzi ngaphansi kokuvezwa yi-UV isikhathi eside.
- Inani Lokugcwala ≥ 90%: Lona umugqa obomvu wokuphepha, ovimbela ifilimu ezintweni ezishintshashintshayo ziye efasiteleni langaphambili ngaphansi kwamazinga okushisa aphezulu, okungathinta ukuphepha kokushayela.
- Ukusebenza Kokuziphilisa: Iphuzu eliyinhloko lokuthengisaImikhiqizo ye-PPF, incike embotsheni yayo ekhethekile.
2. Indlela Yokuqinisekisa Izinto Zokuhlola Ziyaphumelela Ngesikhathi Sokukhiqiza
Ikhwalithi yomkhiqizo yakhelwe enqubweni yokukhiqiza, hhayi nje ekuhlolweni ekugcineni. Ukulawula isigaba ngasinye sokukhiqiza kubalulekile ukuqinisekisa ukuthi izinto ezivivinywe ngenhla ziyaphumelela.
1. Ukulawulwa Kwezinto Ezingavuthiwe (Ukulawulwa Komthombo)
- Ukukhethwa kwe-TPU Pellet:
- Kumelwe usebenzise i-Aliphatic TPU, enezici ezinhle kakhulu zokumelana ne-UV kanye nokulwa nokuphuzi. Lesi yisisekelo sokuphumelela ukuhlolwa kwe-Yellowness Index kanye ne-Weathering Resistance.
- Khetha amamaki e-TPU anokuqukethwe okuphansi okuguquguqukayo kanye nesisindo sama-molecular aphezulu. Lokhu kuyisihluthulelo sokuphumelela ekuhlolweni kwe-Fogging Value kanye ne-VOC.
- Abahlinzeki kumele banikeze i-CoA (Isitifiketi Sokuhlaziya) yeqoqo ngalinye, kanye nokuhlolwa okuvamile okugunyaziwe okuvela eceleni.
- Izinto Zokumboza Nezokunamathela:
- Amafomula okumboza okuziphilisa kanye nokumboza okulwa namabala kumele ahlolwe ngokuqinile ukuguga nokusebenza.
- Ama-Adhesives Azwela Ukucindezela (i-PSA) kumele abe ne-tick ephezulu yokuqala, amandla aphezulu okugcina, ukumelana nokuguga, kanye nokususwa okuhlanzekile ukuqinisekisa ukususwa okuphelele ngemva kokusetshenziswa isikhathi eside.
2. Ukulawulwa Kwenqubo Yokukhiqiza (Ukuzinza Kwenqubo)
- Inqubo Yokuphonsa/Ukushaya Amafilimu Ngokusebenzisa I-Co-extrusion:
- Lawula ngokuqinile izinga lokushisa lokucubungula, isivinini sesikulufu, kanye nesilinganiso sokupholisa. Amazinga okushisa aphezulu kakhulu angabangela ukuwohloka kwe-TPU, okuholela ekuphuzeni nasekushintsheni kokuguquguquka (okuthinta i-YI kanye ne-Fogging Value); amazinga okushisa angalingani abangela ukwehluka kobukhulu befilimu kanye nezakhiwo zokukhanya.
- Indawo yokukhiqiza kumele ibe yindawo yokuhlanza ehlanzekile kakhulu. Noma yiluphi uthuli lungabangela ukukhubazeka kobuso, okuthinta ukubukeka kanye nokunamathela kwengubo.
- Inqubo Yokumboza:
- Lawula ngokunembile ukucindezeleka kwe-coater, isivinini, kanye nokushisa kwe-oven ukuqinisekisa ukumbozwa okufanayo kanye nokumbozwa okuphelele. Ukumbozwa okungaphelele kuholela ekusebenzeni okunciphile kokumbozwa kanye nokungaguquguquki okusele.
- Inqubo Yokwelapha:
- Ifilimu eqediwe idinga ukuqiniswa isikhathi esithile endaweni yokushisa nomswakama engaguquki. Lokhu kuvumela amaketanga ama-molecule kanye nokucindezeleka kwangaphakathi ukuthi kuphumule ngokugcwele, kuzinzise ukusebenza kwe-glue.
3. Ukuhlolwa Kwekhwalithi Ku-inthanethi Nakungaxhunyiwe Ku-inthanethi (Ukuqapha Kwangempela)
- Ukuhlolwa Kwe-inthanethi:
- Sebenzisa amageyiji okujiya aku-inthanethi ukuqapha ukufana kobukhulu befilimu ngesikhathi sangempela.
- Sebenzisa izinhlelo zokuthola amaphutha eziku-inthanethi (amakhamera e-CCD) ukuze uthwebule amaphutha angaphezulu njengamajeli, imihuzuko, namabhamuza ngesikhathi sangempela.
- Ukuhlolwa Okungaxhunyiwe ku-inthanethi:
- Ukuhlolwa Okugcwele Kwelabhorethri: Thatha isampula yeqoqo ngalinye lokukhiqiza bese wenza ukuhlolwa okuphelele ngokwezinto ezingenhla, ukhiqize umbiko ophelele wokuhlolwa kweqoqo.
- Ukuhlolwa Kwesihloko Sokuqala Nokuhlolwa Kokugada: Umqulu wokuqala owenziwe ekuqaleni kokushintshana ngakunye kumele uhlolwe izinto ezibalulekile (isb., ukujiya, ukubukeka, izakhiwo eziyisisekelo zokukhanya) ngaphambi kokuba kuqhubeke ukukhiqizwa ngobuningi. Abahloli bekhwalithi kumele benze ukuhlolwa kokuqapha okuvamile ngokuthatha amasampula ngesikhathi sokukhiqiza.
4. Imvelo kanye Nokugcina Izimpahla
- Zonke izinto zokusetshenziswa kanye nemikhiqizo eqediwe kufanele igcinwe endaweni yokugcina izinga lokushisa elilinganayo kanye nomswakama ukuze kugwenywe ukumuncwa komswakama (i-TPU i-hygroscopic) kanye namazinga okushisa aphezulu.
- Ama-roll efilimu aqediwe kufanele afakwe nge-vacuum kusetshenziswa izikhwama ze-aluminium foil noma ifilimu elwa nama-static ukuvimbela ukungcola kanye nokushiswa kwe-oxidation.
Isiphetho
Inkampani Yezinto Ezintsha Yantai Linghuayenza ukusebenza okuphezulu, okuthembekile kakhuluIfilimu yokuvikela upende ye-TPU, kuwumphumela wokuhlanganiswa kwezinto zokusetshenziswa ezithuthukisiwe, izinqubo zokukhiqiza ngokunemba, kanye nokulawulwa kwekhwalithi okuqinile.
- Izindinganiso Zepharamitha ziyi-"ikhadi lombiko" lomkhiqizo, elichaza isikhundla sawo emakethe kanye nenani lamakhasimende.
- Ukulawulwa Kwenqubo Yokukhiqiza “indlela” kanye “nomzila wokuphila” oqinisekisa ukuthi leli “khadi lombiko” lihlala lihle kakhulu.
Ngokusungula uhlelo lokuqinisekisa ikhwalithi olusebenza ngokugcwele kusukela “ekuthathweni kwezinto zokusetshenziswa” kuya “ekuthunyelweni komkhiqizo okuqediwe,” okusekelwa imishini yokuhlola ethuthukisiwe kanye nobuchwepheshe, i-Yantai Linghua New Material Company ingakhiqiza imikhiqizo ye-PPF ehlangabezana noma edlula ngisho nokulindelwe emakethe, eme inganqotshwa emncintiswaneni wemakethe onamandla.
