Mefuta e Tloaelehileng ea Bophahamo ba Mechini e Fenyang lifilimi
Bophahamo ba mochini o fokang filimi bo khethoa haholo ke bolelele ba bubble ea filimi (tube ea filimi ea polasetiki e tšetsoeng moea). Mefuta e tloaelehileng e bolelele ba limithara tse 2 ho isa ho tse 15 'me e arotsoe ka mefuta e meraro:
1. Mefuta e menyenyane ea laboratori: Ka tloaelo bolelele ba limithara tse 2 ho isa ho tse 4, e loketse R&D kapa-tlhahiso e nyane ea batch (mohlala, Dongguan Topstar TST-200, 3.2 metres ka bolelele).
2. Mefuta ea liindasteri e mahareng-ea boholo bo mahareng: bolelele ba limithara tse 5 ho isa ho tse 10, e emelang 'maraka oa mantlha (mohlala, mochini o fokang lifilimi oa Dalian Rubber & Plastics SJ-65/30, bolelele ba limithara tse 8.5).

Lintlha Tse Ka Sehloohong Tse Amang Bophahamo
1. Bubble Diameter le Blow-Up Ratio: Ha sekhahla se otlang-up se seholo (bubble diameter/die diameter), se tla ba bolelele ba karolo ea ho pholisa. Mohlala, ho hlahisa mulch ea temo ({4}}up ratio 3:1) ho hloka lisebelisoa tse telele ho feta ho hlahisa filimi ea lijo-thollo (blow{7}}up ratio 1.5:1).
2. Moralo oa Sistimi ea Pholiso:
- Mefuta e pholileng ea selikalikoe sa moea e na le bophahamo bo tlase (mohlala, limithara tse 4-6);
- Mefuta ea Mohatsela oa ka Hare (IBC) e hloka sebaka se eketsehileng sa limithara tse 2-3.
3. Tlhophiso ea Line: Ho eketsa li-modules tse kang khatiso ea inline le slitting ho eketsa bolelele ba kakaretso. Mohlala, Guangdong Jinming Precision Machinery MMI-2500 e tla e tloaelehileng ka bolelele ba limithara tse 7.2, e nyolohelang ho limithara tse 9.1 ka ho eketsoa ha slitter.
Joang ho Khetha The Right Height Thepa?
1. Sebaka sa Fektheri se Tšepahalang: Beha bonyane limithara tse 0.5 tsa sebaka se phahameng (mohlala, mochini o bophahamo ba limithara tse 10-o hloka bophahamo bo hlakileng ba limithara tse 10.5).
2. Nahana ka tšebeliso ea filimi:
- Filimi ea ho paka (botenya ba 0.02-0.1mm) hangata e hloka mochini oa limithara tse 6-8.
- Ho haha lera le thibelang metsi (botenya ba 0.3-1mm) ho hloka mochine o molelele ho feta limithara tse 10 ho netefatsa hore ho na le pholile e lekaneng.
3. Lithuto tsa Litaba tsa Indasteri ea Litšupiso:
- Coca{1}}Mohala oa tlhahiso ea lifilimi tsa Cola bottle label (limithara tse 7.8 holimo, Battenfeld-Gloucester, USA);
- Mochini oa filimi oa ho arola betiri oa Tesla (11.3 metres hodimo, Japan Steel Works JSW-1100).
