Tape ya PET vs. Tape ya Washi: Kuphunzira Kwambiri Sayansi Yazinthu, Ukadaulo Wopanga, ndi Malo Ogulitsira
Monga wopanga yemwe ali ndi zaka zambiri zaukadaulo mukupanga tepi ya washi, taona chikhalidwe cha zamanja chikusintha kuchoka pa chikhalidwe chapadera kupita ku chikhalidwe cha ogula ambiri. Mu msika wa matepi omatira omwe akuchulukirachulukira masiku ano, matepi a PET atuluka mwachangu ngati mpikisano wamphamvu, ndikupanga kusiyana kosiyana ndi matepi achikhalidwe a washi kudzera muukadaulo waluso. Nkhaniyi ikupereka kusanthula mwadongosolo kwa kusiyana kwawo kwakukulu pamtundu wazinthu, njira zopangira, ndi zochitika zogwiritsira ntchito, ndikupereka chidziwitso chogwira ntchito kwa akatswiri pantchito.
1. Genetics ya Zinthu Zofunika Kudziwa Makhalidwe a Zamalonda
Tepi ya Washi imachokera ku mgwirizano wabwino pakati pa "mapepala" ndi "ntchito yomatira." Daian Printing yaku Taiwan idayambitsa mndandanda wa 501 Kikusui pogwiritsa ntchito pepala la washi lalitali lokhala ndi ulusi wokonzedwa ndi ukadaulo wodziyimira pawokha, zomwe zidapangitsa kuti 30% ikhale yayitali. Ikaphatikizidwa ndi guluu wa acrylic wochokera m'madzi, izi zimapanga mawonekedwe apadera a "kulimba koyambirira, mphamvu yokhazikika yogwirira, komanso kuchotsa zotsalira". Muzopaka utoto wamagalimoto, tepiyo imasunga zomatira kwa maola awiri pa 110°C popanda kusiya zotsalira, zomwe zimapangitsa kuti ikhale muyezo wamakampani pantchito zophimba nkhope.
Tepi ya PET, yomangidwa pa filimu ya polyester, imasonyeza makhalidwe enieni "opangidwa ndi pulasitiki". Mtundu wa 3M wa JM605P2 uli ndi PET yopyapyala kwambiri ya 0.012mm yokhala ndi guluu wosinthidwa wa acrylic mbali zonse ziwiri, zomwe zimapangitsa kuti "kulimba kwambiri, kukana kutentha kwambiri, komanso kuletsa kuwala kwambiri". Mayeso a labotale amatsimikizira kuti imamatirira maola 24 pa 120°C popanda kulephera, ndipo mtundu wakuda umafikira 99.9% yoletsa kuwala - yofunika kwambiri pakupanga module ya LED backlight.
2. Njira Yopangira Imasintha Kapangidwe ka Zinthu
Mu ukadaulo wosindikiza, tepi ya washi yapanga njira zamakono zopangira zinthu zosiyanasiyana:
• Zophimba zapadera: Mndandanda wa "Starry Night" wa ZHIYU Studio umagwiritsa ntchito utoto wa Daian wopangidwa ndi UV gloss, womwe umafikira makulidwe a inki ya 35μm kudzera mu kusindikiza kwa mitundu isanu ndi umodzi. Izi zimapangitsa kuti 3D nebula iwonekere pansi pa kuwala kolunjika. Njirayi imafuna kukhwima kwa pamwamba pa substrate pansi pa Ra0.8μm kuti igwirizane bwino ndi inki komanso kukhazikika kwa miyeso.
• Zowonjezera zogwira ntchito: Ma tepi ena a washi apamwamba kwambiri amaphatikiza zodzaza za calcium carbonate kuti awonjezere kutseguka ndi 40% pomwe akusunga kusinthasintha, zomwe zimathandiza kuti chophimba cha single-layer chigwiritsidwe ntchito popaka thupi la magalimoto.
Tepi ya PET imayang'ana kwambiri pa uinjiniya wolondola:
• Kukonza pamwamba: TESA 4982 imagwiritsa ntchito matte finishing yokhala ndi micro-scale surface roughness (Ra1.2-1.5μm), zomwe zimapangitsa kuti kuwala kufalikire ndi 40% kuti kuchotse kuwala m'malo okhala ndi kuwala kozungulira kwambiri. Izi zikugwirizana ndi miyezo ya ISO 13655 yowunikira pazenera la mafoni.
• Kuwongolera miyeso: JM1030B yoyenerera Foxconn imasunga kulekerera kwa makulidwe a substrate mkati mwa ±0.001mm, zomwe zimathandiza kuti 0.02mm idulidwe bwino pogwiritsa ntchito FPC reinforcement applications.
3. Kugwiritsa Ntchito Zochitika Zoyendetsa Msika Kusiyanitsa
Tepi ya Washi imayang'anira magawo atatu a chikhalidwe ndi luso:
• Zokongoletsa zolemba: Matepi a ku Taiwan (kalabu) ali ndi mawonekedwe otalikirapo (90-200cm/roll) okhala ndi mitu yotsatizana. Mndandanda wa "Sakura Feather" wa KIKEN umaphatikiza inki yoyera, utoto wonyezimira, ndi kupondaponda kotentha m'mapangidwe 12 otsatizana, kuthandizira zojambula zotsatizana zotsatizana.
• Kukulunga Mphatso: Kampani ya MT ku Japan yapanga mitundu ya 48mm m'lifupi pogwiritsa ntchito njira ya washi yotha kusinthasintha popanga uta wa 3D. Mphamvu ya 0.8N/25mm yoboola ya guluu imatsimikizira kuti ikhazikika bwino panthawi yopaka yokha.
• Kuphimba nkhope m'mafakitale: Mndandanda wa Daian 701 umakonza mphamvu yomasula pansi pa 0.8N/25mm kuti igwirizane ndi zida zophimba nkhope zothamanga kwambiri popanga zinthu zamagetsi.
Tepi ya PETimachita bwino kwambiri pa ntchito zamafakitale:
• Kukhazikitsa magetsi: 3M 9795B imakwaniritsa kufalikira kwa kuwala kwa 92% ndi <1.5% ya utsi pogwiritsa ntchito PET yowoneka bwino, ikukwaniritsa zofunikira zolumikizira zowonetsera zamagalimoto.
• Njira zotenthetsera kwambiri: SIDITEC DST-20 imasunga umphumphu wa kapangidwe kake pa 200°C kwa mphindi 30, zomwe zimaletsa kupangika kwa carbon mu batri yatsopano yamagetsi.
• Ma Microelectronics: Ma tepi a PET okhala ndi makulidwe a 0.003mm amathandizira kugwirira ntchito kwa semiconductor wafer, komwe kukhazikika kwa mawonekedwe kumakhudza mwachindunji kuchuluka kwa zokolola.
Pamene makampani opanga matepi omatira akusintha kuchoka pa “mpikisano wazinthu” kupita ku “mayankho azinthu,” kumvetsetsa chifukwa chaukadaulo chomwe chili kumbuyo kwa zinthu zakuthupi kumakhala kwanzeru kwambiri kuposa kungoyerekeza zinthu zokha.kupanga tepi ya washiTikayang'ana malo osungiramo zinthu, tikukhazikitsa njira yatsopano ya "Material Database + Process Lab" kuti tifufuze ntchito zogwiritsira ntchito washi komanso kusunga luso lachikhalidwe. Njira ziwirizi zosungira cholowa ndi kusokoneza ukadaulo zitha kukhala njira yabwino kwambiri yosinthira mafakitale.
