Chovala chofewa chatsopano chopangidwa ndi chikopa cha chikopa cha holographic chowonekera cha vinilu chonyezimira

Chikopa chonyezimira
Ufa wonyezimira umakakamira pa chikopa cha PU kapena PVC kuti chikopacho chikhale chapadera chonyezimira. Izi pamodzi zimatchedwa "glitter leather" m'makampani a zikopa. Kukula kwa ntchito kukukulirakulira, ndipo kwakula kuchokera ku nsapato kupita ku ntchito zamanja, zowonjezera, zokongoletsa, ndi zina zambiri.

Njira Yopanga
Ufa wonyezimira umapangidwa ndi filimu ya poliyesitala (PET) yomwe imayikidwa koyamba kukhala yoyera ya silvery, kenako ndi utoto ndikudinda. Kumwamba kumapanga mawonekedwe owala komanso okopa maso. Maonekedwe ake ali ndi ngodya zinayi ndi ma hexagon, ndipo zofotokozera zimatsimikiziridwa ndi kutalika kwa mbali. , monga kutalika kwa mbali za ngodya zinayi nthawi zambiri ndi 0.1mm, 0.2mm ndi 0.3 mm, etc.
Chifukwa cha tinthu tating'ono ting'onoting'ono, ngati mumagwiritsa ntchito chikopa chopangidwa ndi polyurethane, ndizosavuta kukanda pepala lotulutsa mbali imodzi. Kumbali ina, chifukwa cha kuchepa kwa kuchuluka kwake, zimakhala zovuta kuti ufa wonyezimira utseke bwino mtundu wa maziko a polyurethane, zomwe zimapangitsa kuti pakhale mtundu wosiyana. Panthawiyi, opanga nthawi zambiri amagwiritsa ntchito kupopera mbewu mankhwalawa: choyamba ikani zomatira za polyurethane pa chikopa chonyowa cha polyurethane, kenako perekani ufa wonyezimira ndikuchiphwanya moyenerera kuti chikhale cholimba, kenako ndikuchiyika pa 140 ~ Dry. pa 160 ℃ ndi okhwima kwa maola 12 ~ 24. Zomatira zikatha kuchiritsidwa, yeretsani ufa wonyezimira wowonjezera ndi tsache la bristle. Chikopa chonyezimira chomwe chimapangidwa ndi njirayi chimakhala ndi mawonekedwe amphamvu amitundu itatu, mitundu yowala, ndipo chimawonetsa zowala mosiyanasiyana kuchokera kumakona osiyanasiyana, koma chimakhala ndi kukana kovala bwino.

Njira yopopera mbewu pa glue pamwamba
Pachikopa chonyezimira chopangidwa ndi njira yopopera mbewu mankhwalawa, gwiritsani ntchito tsache poyamba kusesa ufa wonyezimira wonyezimira wokhala ndi zomatira pang'ono, ndiyeno mugwiritseni ntchito mfuti yopopera kupopera makasulidwe otsika, olimba kwambiri, ndi gloss yayikulu pamwamba. Polyurethane mandala utomoni ndiye zouma pa 80 ~ 120 ℃, kuti PU utomoni amapanga wosanjikiza woonda zoteteza pamwamba pa glitter ufa, ndi bwino adhesion pakati pa glitter ufa, kwambiri kuwongolera Iwo ali mkulu abrasion kukana ndipo akhoza kusunga mawonekedwe ake apadera amitundumitundu. Pofuna kuchepetsa zotsatira za pores chifukwa cha zosungunulira kuyanika pa kuwonekera, njira kupopera mbewu mankhwalawa ndi kuyanika mu magawo akhoza anatengera kusintha poyera.
Kutulutsa njira yokutira mapepala
Njira yotulutsira mapepala otulutsa ndikuwonjezera utomoni wowuma wowonekera pamwamba pa chikopa chonyezimira, ndipo njira yake yopangira imanena za polyurethane youma. Gwiritsani ntchito chikopa chonyezimira chomwe chimapangidwa ndi njira yopopera mankhwala ngati maziko opangira laminate pamapepala otulutsa. Njira yeniyeniyi ndi iyi: pepala lotulutsa galasi - lopangidwa ndi utomoni woonekera wa polyurethane - 130 ~ 150 ℃ x 1.5 min kuyanika - yokutidwa ndi yokutidwa pawiri Zigawo: zomatira za polyurethane - Kuphika pang'ono pa 40 ~ 50 ℃ - Chikopa cha Composite glitter - Kukhwima ndi limbitsani kwa maola 12-24 - Alekanitse chikopa chonyezimira kuchokera papepala lotulutsa ndi mpukutu izo.
Pamwamba pa chikopa chonyezimira chonyezimira chimapanga mawonekedwe owoneka bwino, owoneka ngati galasi, omwe amathandizira kuti chikopacho chikhale chofanana ndi chikopa chochita kupanga cha polyurethane, chimathandizira kwambiri kukana kwake, ndikusunga kufewa kwake. Ndiwolimba kwambiri ndipo imakhala ndi kristalo pamwamba pake. Ikhoza kugwiritsidwa ntchito popanga nsapato zamasewera, matumba a lamba, ndi zina zomwe zimafuna kukana kuvala kwambiri.

njira yamagulu
Njira yophatikizira ndikuphatikiza filimu yowoneka bwino pamwamba pa chikopa chonyezimira. Ndondomekoyi ili motere: choyamba, gwiritsani ntchito tsache la tsitsi kuti musese ufa wonyezimira wonyezimira wosamata bwino pachikopa chonyezimira chopangidwa ndi njira yopopera mbewu mankhwalawa. Kuyeretsa, ndiye utsi mlingo woyenera kwambiri mandala otentha-Sungunulani zomatira polyurethane, ndi ntchito galasi gudumu kuphatikiza ndi TPU mandala filimu ndi makulidwe a 0.07 ~ 0.10mm pa 150 ~ 160 ℃ kupanga wosanjikiza pamwamba pa chikopa chonyezimira. chitetezo chosanjikiza kuti chiwonjezere kukana kwake.
Chinsinsi cha njira yophatikizika ndikusankha zomatira zotentha za polyurethane, filimu yowonekera ya TPU ndi zinthu zophatikizika. Kumbali imodzi, zomatira zotentha za polyurethane ziyenera kukhala zowonekera kwambiri komanso kukana chikasu. Kumbali ina, malo osungunuka ayenera kukhala pakati pa 150 ndi 160 ° C. Makulidwe ndi kuuma kwa filimu yowonekera ya TPU iyenera kukhala yocheperako. Kanema wowonekera wa TPU ndi wandiweyani kwambiri, zomwe zimakhudza kumva komanso kuwonekera. , woonda kwambiri amakhudza flatness pamwamba, makulidwe ambiri ndi 0.07 ~ 0.10 mm; pamene kuuma kuli kwakukulu, chikopa chophatikizika chimamva cholimba kwambiri, ndipo ngati chiri chochepa kwambiri, chidzakhala chovuta kugwira ntchito. Nthawi zambiri, kuuma kwa Shore A ndi 50 ~ 80; Magalasi pamwamba ayenera kugwiritsidwa ntchito pophatikizana Gudumu limaphatikizidwa ndi kuthamanga kwa 30kg kuti zitsimikizire kufulumira kwake.

Kuyerekeza kwanjira
Njira zitatu zomwe zili pamwambazi zili ndi ubwino ndi zovuta zake. Pamwamba pa chikopa chopopera chopopera chimasungabe mawonekedwe ake opindika komanso owoneka bwino, ndipo kukana kovala kumakhala bwino kwambiri, koma kukana kupindika sikumakhala bwino. Njira yophimba imapangitsa kuti pamwamba pakhale bwino komanso kusungabe kufewa kwake. Ili ndi kukana kwabwino kwambiri koma imakonda makwinya ikapindika. Njira yophatikizika imapangitsanso kuti pamwamba ikhale yosalala komanso imakhala ndi kukana kovala bwino komanso kukana kupindika. Komabe, chifukwa filimu yophatikizika imakhala ndi makulidwe ake, imamva movutikira. Kuphatikiza apo, filimu ya TPU ikadali yakhanda ku China, yotsika kwambiri komanso yosakhazikika. Zimadalira kwambiri zogulitsa kunja ndipo mtengo wake ndi wapamwamba.
Pomaliza
Chikopa cha Glitter PU chakula mwachangu m'zaka zaposachedwa. Panthawi yopangira, opanga akuyenera kukonzanso mosiyanasiyana malinga ndi momwe amagwiritsidwira ntchito ndi zofunikira zosiyanasiyana kuti apititse patsogolo zinthu kuti zikwaniritse zofunikira zamakasitomala kwambiri.
