Makina Owomba Mafilimu Omwe Amakhala Patali
Kutalika kwa makina owombera filimu kumatsimikiziridwa makamaka ndi kutalika kwa filimu ya filimuyi (chubu la filimu ya pulasitiki). Mitundu yodziwika bwino imachokera ku 2 mpaka 15 metres ndipo imagawidwa m'magulu atatu:
1. Mitundu ya ma labotale ang'onoang'ono: Nthawi zambiri amatalika mamita 2 mpaka 4, oyenera R&D kapena ang'onoang'ono-kupanga magulu ang'onoang'ono (monga Dongguan Topstar TST-200, mamita 3.2 muutali).
2. Mitundu yamafakitale-yapakati: 5 mpaka 10 m'litali, kuimira msika wamba (monga makina owuzira mafilimu a Dalian Rubber & Plastics SJ-65/30, mamita 8.5 muutali).
3. Large, high-speed production lines: Reifenhäuser three-layer co-extrusion lines, 12 to 15 meters in height, are used for wide-width film production (e.g., the German Reifenhäuser three-layer co-extrusion line, 13.6 meters in height).
*Magwero azidziwitso: Pulasitiki Machinery Design Handbook (kope la 2021) ndi luso lazopangapanga lomwe likupezeka poyera. *
Zinthu Zofunika Kwambiri Zokhudza Kutalika
1. Buluu Diameter ndi Blow-Up Ratio: Kukula kwa kuphulitsa-mmwamba chiŵerengero (bubble diameter/die diameter), kumapangitsa kuti gawo lozizirira likhale lalitali. Mwachitsanzo, kupanga mulch waulimi (kuphulika{4}}ku chiŵerengero cha 3:1) kumafuna zipangizo zazitali kuposa kupanga filimu yotsatsira (kuphulika{7}}chiŵerengero cha 1.5:1).
2. Mapangidwe a Dongosolo Lozizira:
- Mitundu yozizirira mphete yamphepo imakhala yotsika (monga 4-6 mita);
- Mitundu Yozizirira M'kati (IBC) imafunika danga lowonjezera la 2-3 mita.
3. Kukonzekera kwa Mzere: Kuwonjezera ma modules monga kusindikiza kwapakati ndi kudula kumawonjezera kutalika konse. Mwachitsanzo, Guangdong Jinming Precision Machinery MMI-2500 imabwera yokhazikika yokhala ndi kutalika kwa 7.2 metres, yomwe imakwera mpaka 9.1 metres ndikuwonjezera slitter.
Momwe Mungasankhire Zida Zamsinkhu Woyenera?
1. Malo Ogwirizana ndi Factory: Sungani osachepera 0.5 metres kuchokera pamwamba (monga makina 10-otalika mamita 10 amafunikira mtunda wowoneka bwino wa mita 10.5).
2. Ganizirani momwe filimu imagwiritsidwira ntchito:
- Kanema wolongedza (kukhuthala 0.02-0.1mm) nthawi zambiri amafuna makina a 6-8 mita.
- Kupanga kansalu koletsa madzi (kukhuthala 0.3-1mm) kumafuna makina otalikirapo kuposa mamita 10 kuti aziziziritsa mokwanira.
3. Maphunziro a Nkhani Zamakampani:
- Coca-Mzere wopangira mafilimu a Cola bottle label (kutalika kwa mita 7.8, Battenfeld-Gloucester, USA);
- Makina afilimu olekanitsa batire a Tesla (mamita 11.3 m'mwamba, Japan Steel Works JSW-1100).
