Umahluko ophambili ngulo: Ifilimu esisiseko yinto enye "engagqitywanga ngokupheleleyo", ngelixa ifilimu egqityiweyo iyinto edityanisiweyo enamaleko amaninzi edibanisa imisebenzi emininzi. Ngamafutshane, ifilimu esisiseko yi-skeleton, kwaye ifilimu egqityiweyo yimfazwe exhotyiswe ngokupheleleyo elungele ukusebenza.
Itheyibhile engezantsi icacisa ngokucacileyo umahluko:
| Umbono | Ifilimu esisiseko yeTPU PPF | Ifilimu egqityiweyo yeTPU PPF |
|---|---|---|
| Inkcazo | Izinto ezigqityiweyo kancinci, kuphela umqolo oyintloko wefilimu egqityiweyo. | Imveliso yokugqibela ilungele ukufakwa ngqo kwipeyinti yemoto. |
| Indima Engundoqo | Ibonelela ngokhuseleko oluphambili lomzimba (ukuxhathisa impembelelo, amandla okuxinana). | Ibonelela ngokhuseleko olupheleleyo olugubungela ukuqina komzimba, inkangeleko, kunye nokugcinwa lula. |
| Ulwakhiwo Lomzimba | Umaleko omnye – izinto zeTPU kuphela. | I-composite eneeleya ezininzi – idla ngokuba ne-topcoat, i-TPU base film, kunye ne-adhesive layer. |
| Imisebenzi ephambili | - Ukhuseleko olusisiseko: ukuxhathisa impembelelo, ukuxhathisa iitshiphusi. - Ukuguquguquka kunye nokwelula: kulula ukuhambelana neegophe zemoto ngexesha lokufakwa. | - Ukuziphilisa: imikrwelo emincinci iyanyamalala xa kushushu. - Ukumelana nokuba tyheli: iifilimu ezikumgangatho ophezulu zisebenzisa i-aliphatic TPU. - Ukumelana namabala kunye nokucoca okulula: i-top coat ephobisayo/ephobisayo. - Ukunamathela okuqinileyo: umaleko wokuncamathelisa ozinikeleyo uqinisekisa ukubopha okuqinileyo ngaphandle kokonakalisa ipeyinti yokuqala. |
Umahluko ongundoqo oneenkcukacha
1. Ifilimu esisiseko: into enye, "i-skeleton"
Ifilimu esisiseko yifilimu yeTPU ecocekileyo (thermoplastic polyurethane). Yisiseko solwakhiwo lwefilimu egqityiweyo, emisela iipropati zomzimba ezisisiseko ezifana nokuxhathisa iitships zamatye. Umgangatho wayo uxhomekeke kakhulu kuhlobo lwee-TPU pellets. Kukho iintlobo ezimbini eziphambili ezithengiswayo:
| Ipropati | I-TPU ye-Aliphatic | I-TPU enevumba elimnandi |
|---|---|---|
| Ulwakhiwo lwemolekyuli | Akukho rings ze-benzene, isakhiwo esizinzileyo. | Iqulethe izangqa ze-benzene, ezisengozini yokuhlaselwa yi-UV. |
| Ukumelana nokuba tyheli | Igqibelele kakhulu – ingahlala iminyaka emi-5–10 nangaphezulu. | Imbi – isenokuba tyheli ngokubonakalayo kwiinyanga ezi-6-12. |
| Ukuqina/Amandla | Kungcono, kubonelela ngokhuseleko oluqinileyo. | Amandla aphakathi, aphantsi kakhulu. |
| Indawo yemarike | Ikumgangatho ophezulu, isetyenziswa kwi-PPF yeprimiyamu. | Isetyenziswa phakathi ukuya kwesezantsi, idla ngokusetyenziswa kwiifilimu ezingabizi kakhulu. |
2. Ifilimu egqityiweyo: i-multi-layer composite, "imveliso epheleleyo"
Ifilimu egqityiweyo yimveliso yokugqibela elungele ukufakwa kwipeyinti yemoto. Ukusebenza kwayo kudlula kakhulu ifilimu esisiseko esinye. Ifilimu egqityiweyo yomgangatho ophezulu sisakhiwo esichanekileyo esineengqimba ezininzi apho umaleko ngamnye unendima ethile:
- Umaleko ophezulu: Uboya obusebenzayo – Olu “lusu” oludibana ngqo nehlabathi langaphandle, olubonelela ngeenzuzo ezibonakalayo zomsebenzisi.
- Ukuziphilisa: Iimolekyuli zokugquma “ziyakhumbula” kwaye zibuyisele imo yazo yokuqala xa zishushu, zizalise imikrwelo emincinci.
- Ukumelana namabala kunye nokucocwa okulula: I-Nanotechnology idala iipropati zokungathandi amanzi kunye nokungathandi i-oleophobic, ixhathisa ukungcoliswa kweentaka, imvula ene-asidi, kunye nezinye izinto ezirhabaxa.
- Ukuphucula ukukhanya: Kuyandisa ukukhanya kwepeyinti ukuze ibonakale ngcono.
- Umaleko ophakathi:Ifilimu esisiseko yeTPU– Le yi "skeleton" yefilimu egqityiweyo, kanye ifilimu esisiseko echazwe apha ngasentla. Imisela amandla okukhusela angundoqo omzimba.
- Umaleko ongezantsi: Umaleko oncamathelayo – Le “yibhulorho” edibanisa ifilimu nepeyinti yemoto.
- I-tack yokuqala ephantsi: Ivumela ukutshintshwa okulula ngexesha lokufakwa.
- Amandla aphezulu okubamba: Ukuncamathela kuyanda ngokuhamba kwexesha kunye nobushushu, okuqinisekisa ukubopha okuhlala ixesha elide.
- Ukususwa okucocekileyo: Izincamathelisi ezisemgangathweni ophezulu zenzelwe ngokukodwa ukuba zingashiyi ntsalela kwipeyinti xa ifilimu isusiwe, nto leyo ekhusela ukugqitywa kwefektri yokuqala.
