Kusiyana kwakukulu ndi: Filimu yoyambira ndi chinthu chimodzi "chomalizidwa pang'ono", pomwe filimu yomalizidwa ndi chinthu chokhala ndi zigawo zambiri chomwe chimagwirizanitsa ntchito zingapo. Mwachidule, filimu yoyambira ndi chigoba, ndipo filimu yomalizidwa ndi msilikali wokonzeka kuchitapo kanthu.
Gome ili m'munsimu likufotokoza momveka bwino kusiyana kwake:
| Mbali | Filimu Yoyambira ya TPU PPF | Filimu Yomalizidwa ya TPU PPF |
|---|---|---|
| Tanthauzo | Zinthu zomalizidwa pang'ono, chigoba chapakati cha filimu yomalizidwa chokha. | Chomaliza chakonzeka kuyikidwa mwachindunji pa utoto wa galimoto. |
| Udindo Waukulu | Amapereka chitetezo champhamvu chakuthupi (kukana kukhudzidwa, mphamvu yokoka). | Amapereka chitetezo chokwanira chomwe chimaphimba kulimba, mawonekedwe, komanso kukonza kosavuta. |
| Kapangidwe ka Thupi | Chigawo chimodzi - zinthu za TPU zokha. | Chophatikiza cha zigawo zambiri - nthawi zambiri chimakhala ndi topcoat, TPU base film, ndi glue layer. |
| Ntchito Zofunika Kwambiri | - Chitetezo chachikulu: kukana kugunda, kukana chip. - Kusinthasintha & kutambasula: zosavuta kutsatira ma curve a galimoto panthawi yoyikira. | - Kudzichiritsa: mikwingwirima yopyapyala imatha ndi kutentha. - Kukana kwachikasu: mafilimu apamwamba kwambiri amagwiritsa ntchito TPU ya aliphatic. - Kukana banga ndi kuyeretsa kosavuta: topcoat yoopsa ndi madzi/yoopsa ndi oleophobic. - Kumatirira mwamphamvu: guluu wodzipereka umathandiza kuti ugwirizane bwino popanda kuwononga utoto woyambirira. |
Kusiyana kwakukulu kwapakati
1. Filimu yoyambira: chinthu chimodzi, "chigoba"
Filimu yoyambira ndi filimu ya TPU (thermoplastic polyurethane). Ndi maziko a kapangidwe ka filimu yomalizidwa, zomwe zimatsimikizira zinthu zoyambira monga kukana miyala. Ubwino wake umadalira kwambiri mtundu wa ma TPU. Pali mitundu iwiri ikuluikulu pamsika:
| Katundu | Aliphatic TPU | TPU Yonunkhira |
|---|---|---|
| Kapangidwe ka maselo | Palibe mphete za benzene, kapangidwe kokhazikika. | Ili ndi mphete za benzene, zomwe zimakhudzidwa ndi UV. |
| Kukana kwachikasu | Zabwino kwambiri - zimatha kukhala zaka 5-10 kapena kuposerapo. | Zoipa - zimatha kukhala zachikasu mkati mwa miyezi 6-12. |
| Kulimba/Mphamvu | Zabwino, kupereka chitetezo champhamvu. | Mphamvu yapakati, yotsika pang'ono. |
| Malo omwe msika uli | Yokwera mtengo kwambiri, yomwe imagwiritsidwa ntchito mu PPF yapamwamba. | Yapakati mpaka yotsika, nthawi zambiri imagwiritsidwa ntchito m'mafilimu otsika mtengo. |
2. Filimu yomalizidwa: multi-layer composite, "chogulitsa chathunthu"
Filimu yomalizidwa ndi chinthu chomaliza chokonzeka kuyikidwa pa utoto wa galimoto. Kagwiridwe kake ka ntchito kamapitirira filimu imodzi yokha. Filimu yomalizidwa bwino kwambiri ndi kapangidwe kolondola ka zigawo zambiri komwe gawo lililonse limakhala ndi ntchito yakeyake:
- Chovala chapamwamba: Chovala chapamwamba chogwira ntchito - Ichi ndi "khungu" lomwe limakhudzana mwachindunji ndi dziko lakunja, zomwe zimapangitsa kuti ogwiritsa ntchito aziona bwino kwambiri.
- Kudzichiritsa: Mamolekyu ophimbawo "amakumbukira" ndikubwezeretsa mawonekedwe awo oyambirira akatenthedwa, ndikudzaza mikwingwirima yaying'ono.
- Kukana banga ndi kuyeretsa kosavuta: Nanotechnology imapanga mphamvu zodana ndi madzi ndi oleophobic, kukana ndowe za mbalame, mvula ya asidi, ndi zinthu zina zowononga.
- Kuwala kowala: Kumawonjezera kuwala kwa utoto kuti uwoneke bwino.
- Gawo lapakati:Filimu yoyambira ya TPU- Ichi ndi "chigoba" cha filimu yomalizidwa, ndendende filimu yoyambira yomwe yafotokozedwa pamwambapa. Imeneyi ndi njira yodziwira mphamvu yaikulu yotetezera thupi.
- Gawo la pansi: Gawo lomatira - Uwu ndi "mlatho" wolumikiza filimuyo ndi utoto wa galimoto.
- Kuyika koyambira kochepa: Kumalola kuyikanso mosavuta panthawi yoyika.
- Mphamvu yogwira kwambiri: Kugwira kumawonjezeka pakapita nthawi komanso kutentha, zomwe zimapangitsa kuti chigwirizanocho chikhale cholimba kwa nthawi yayitali.
- Kuchotsa koyera: Magulu abwino kwambiri amapangidwa mwapadera kuti asasiye zotsalira pa utoto filimu ikachotsedwa, kuteteza mawonekedwe oyambirira a fakitale.
