Tataiso ea ho qetela ea ho Otlolla Filimi: Mefuta, Likopo, le Malebela a Khetho (Ntlafatso ea 2025)

1. Ho Utloisisa Filimi ea Otlolla: Maikutlo a Motheo le Tlhahlobo ea Maraka

Filimi e otlolohileng (eo hape e tsejoang e le ho phuthela ka mokhoa o otlolohileng) ke filimi ea polasetiki e otlolohileng e sebelisetsoang ho kopanya le ho tsitsisa meroalo ea pallet nakong ea polokelo le lipalangoang. Hangata e entsoe ka thepa ea polyethylene (PE) joalo ka LLDPE (Linear Low-Density Polyethylene) 'me e entsoe ka mekhoa ea ho lahla kapa ho foka. Mmaraka oa lefats'e oa lifilimi tsa polyethylene o ne o le boleng ba $ 82.6 bilione ka 2020 mme ho lebelletsoe hore o tla fihla ho $128.2 bilione ka 2030, ka kakaretso ea chelete e kenang ea polyethylene. lifilimi marakeng. Asia-Pacific e laola 'maraka ka hoo e ka bang halofo ea karolo ea lefats'e mme ho nahanoa hore e tla ngolisa sekhahla se phahameng ka ho fetisisa sa kholo.

2. Mefuta ea Lifilimi tse Otlollang: Lisebelisoa le Papiso ea Tlhahiso

2.1 Filimi ea ho otlolla letsoho
E etselitsoe tšebeliso ea matsoho, lifilimi tse otlollang matsoho hangata li tloha ho li-micron tse 15-30 ka botenya. Li na le matla a tlase a otlollang (150% -250%) empa thepa e phahameng ea ho khomarela bakeng sa ts'ebeliso e bonolo ea matsoho. Tsena li loketse lintho tse nang le sebopeho se sa tloaelehang le ts'ebetso ea molumo o tlase.

2.2 Filimi ea ho otlolla mochini
Lifilimi tse otlollang mochini li etselitsoe tšebeliso ea lisebelisoa tse ikemetseng. Ka tloaelo li tloha ho 30-80 microns ka botenya bakeng sa meroalo e boima. Lifilimi tsa mochini li ka aroloa hape ka lifilimi tse otlollang matla (ho hanyetsa ka matla) le lifilimi tsa pele ho ho otlolla (300%+ matla a ho otlolla).

2.3 Lifilimi tse khethehileng tsa ho otlolla

Lifilimi tse hanyetsanang le UV: E na le li-additives ho thibela ho senyeha ha khanya ea letsatsi, tse loketseng polokelo ea kantle.

Lifilimi tse kentsoeng moea: E fana ka li-micro-perforations ho lumella mongobo hore o phonyohe, o loketseng lihlahisoa tse ncha.

Lifilimi tsa Mebala: E sebelisoa bakeng sa ho kenya likhoutu, ho kenya letšoao kapa tšireletso e bobebe.

3. Lintlha tsa Bohlokoa tsa Theknoloji: Ho utloisisa Parameters ea Ts'ebetso

Ho utloisisa lintlha tsa tekheniki ho netefatsa khetho e nepahetseng ea lifilimi:

Botenya: E lekantsoe ka li-microns (μm) kapa mils, e khetholla matla a motheo le ho hanyetsa ho phunya. Mefuta e tloaelehileng: 15-80μm.

Sekhahla sa ho otlolla: Peresente ea filimi e ka otlolloa pele ho kopo (150% -500%). Litefiso tse phahameng li bolela ho koaheloa ho eketsehileng ha roll ka 'ngoe.

Matla a tšepe: Matla a hlokahalang ho senya filimi, e lekantsoeng ka MPa kapa psi. Bohlokoa bakeng sa meroalo e boima.

Khomarela/ Ho khomarela: Bokhoni ba filimi ea ho itšoarella ntle le likhomaretsi. E bohlokoa bakeng sa botsitso ba mojaro.

Puncture Resistance: Bokhoni ba ho hanela ho taboha ho tloha likhutlong tse bohale kapa mecheng.

Load Retention: Bokhoni ba filimi ea ho boloka tsitsipano le ho boloka mojaro ka nako.

4. Maemo a Kopo: Moo le Mokhoa oa ho Sebelisa Lifilimi tse Fapaneng tsa Ho otlolla

4.1 Thepa le Bobolokelo
Lifilimi tse otlollang li netefatsa botsitso ba mojaro oa yuniti nakong ea lipalangoang le polokelo. Lifilimi tsa maemo a tloaelehileng (20-25μm) li sebetsa bakeng sa thepa e ngata ea mabokose, athe meroalo e boima (lisebelisoa tsa kaho, lino) e hloka limaraka tsa pele (30-50μm+) tse nang le khanyetso e phahameng ea ho phunya.

4.2 Indasteri ea Lijo le Lino
Lifilimi tse sireletsehileng tsa lijo li sireletsa lintho tse senyehang nakong ea kabo. Lifilimi tse kentsoeng moea li lumella moea bakeng sa lihlahisoa tse ncha, athe lifilimi tse hlakileng haholo li nolofalletsa ho tseba lintho tse ka hare.

4.3 Tlhahiso le Indasteri
Lifilimi tse otlolohileng tse boima (ho fihla ho 80μm) likarolo tsa tšepe tse sireletsehileng, thepa ea mohaho le thepa e kotsi. Lifilimi tse hanyetsanang le UV li sireletsa thepa e bolokiloeng ka ntle ho senyeha ha boemo ba leholimo.

5. Tataiso ea Khetho: Ho Khetha Filimi e nepahetseng ea ho otlolla bakeng sa litlhoko tsa hau

Sebelisa matrix a liqeto bakeng sa khetho e nepahetseng ea lifilimi:

1.Mojaro Litšobotsi:

Meroalo e bobebe (<500kg): lifilimi tsa letsoho tsa 17-20μm kapa lifilimi tsa mochini oa 20-23μm.

Meroalo e mahareng (500-1000kg): lifilimi tsa letsoho tsa 20-25μm kapa lifilimi tsa mochini oa 23-30μm.

Meroalo e boima (> 1000kg): lifilimi tsa letsoho tsa 25-30μm kapa lifilimi tsa mochini tsa 30-50μm +.

2.Maemo a Lipalangoang:

Ho tsamaisoa ha lehae: Lifilimi tse tloaelehileng.

Litsela tse telele / tse mpe: Lifilimi tse sebetsang hantle tse nang le meroalo e ntle haholo.

Polokelo ea kantle: Lifilimi tse hanyetsanang le UV

3.Mehopolo ea Thepa:

Ho phuthela ka letsoho: Lifilimi tse tloaelehileng tsa letsoho.

Mechini ea semi-automatic: Lifilimi tse tloaelehileng tsa mochini.

Li-automation tsa lebelo le phahameng: Lifilimi tse otlollang pele.

Foromo ea Palo ea Litšenyehelo:
Litšenyehelo ka Mojaro = (Theko ea Moqolo oa Lifilimi ÷ Bolelele Kakaretso) × (Filimi e Sebelisitsoe Mojaro ka mong)

6. Lisebelisoa tsa Kopo: Manual vs. Automated Solutions

Tšebeliso ea Manual:

Lisebelisoa tsa mantlha tsa lifilimi li fana ka ts'ebetso ea ergonomic le taolo ea tsitsipano.

Mokhoa o nepahetseng: boloka tsitsipano e tsitsitseng, ho fetana ho feta 50%, boloka qetello hantle.

Liphoso tse tloaelehileng: ho otlolla ho fetelletseng, ho fetella ho sa lekaneng, ho koaheloa ka holimo/tlase ho sa lokelang.

Mechini ea Semi-Automatic:

Li-wrappers tse fetohang li potoloha mojaro ha u ntse u sebelisa filimi.

Melemo ea bohlokoa: tsitsipano e tsitsitseng, ho fokotseha ha mosebetsi, tlhahiso e phahameng.

E loketse ts'ebetso ea li-volume tse mahareng (meroalo e 20-40 ka hora).

Ka ho Feletseng Automatic Systems:

Li-wrappers tsa liroboto bakeng sa litsi tsa kabo ea boleng bo holimo.

Fumana meroalo e 40-60+ ka hora ka ho kenya letsoho ho fokolang ha opereishene.

Hangata e kopantsoe le litsamaiso tsa conveyor bakeng sa ts'ebetso e se nang moeli.

7. Maemo a Indasteri le Tlhahlobo ea Boleng

TheASTM D8314-20standard e fana ka litataiso bakeng sa tlhahlobo ea ts'ebetso ea lifilimi tse otlolohileng tse sebelisitsoeng le ho phuthela. Liteko tsa bohlokoa li kenyelletsa:

Otlolla Tshebetso: E lekanya boitšoaro ba filimi tlas'a tsitsipano nakong ea kopo.

Load Retention: E lekola hore na filimi e boloka matla hantle hakae ha nako e ntse e ea.

Puncture Resistance: E etsa qeto ea ho hanyetsa ho taboha ho tloha likarolong tse bohale.

Cling Properties: E lekola litšobotsi tsa filimi ea ho itšoarella.

Lifilimi tsa boleng bo holimo le tsona li tlameha ho latela maemo a naha a bohlokoa joalo ka BB/T 0024-2018 ea China bakeng sa filimi e otlolohileng, e hlalosang litlhoko tsa thepa ea mochini le ho hanyetsa ho phunya.

8. Maikutlo a Tikoloho: Moshoelella le ho Recycle

Maikutlo a tikoloho a fetola indasteri ea lifilimi:

Lifilimi tsa Litaba tse Recycled: E na le lisebelisoa tsa morao-rao tsa indasteri kapa tsa morao-rao tsa bareki (ho fihla ho 50% lihlahisoa tsa pele).

Phokotso ea Mohloli: Lifilimi tse tšesaane, tse matla (nanotechnology e nolofalletsang lifilimi tsa 15μm tse nang le ts'ebetso ea 30μm) li fokotsa tšebeliso ea polasetiki ka 30-50%.

Mathata a ho Recycle: Lisebelisoa tse tsoakiloeng le tšilafalo li thatafatsa mekhoa ea ho tsosolosa.

Lisebelisoa Tse Ling: Bio-based PE le lifilimi tse ka 'nang tsa e-ba manyolo ka litlama tse ntseng li ntlafatsoa.

9. Mekhoa ea Kamoso: Litlhahiso le Litsela tsa Mmaraka (2025-2030)

Mmaraka oa lefats'e oa lifilimi tsa polyethylene o tla fihla ho $ 128.2 bilione ka 2030, o ngolisa CAGR ea 4.5% ho tloha 2021 ho isa 2030. Mekhoa ea bohlokoa e kenyelletsa:

Lifilimi tse bohlale: Li-sensor tse kopantsoeng bakeng sa ho latela botšepehi ba mojaro, mocheso le litšisinyeho.

Nanotechnology: Lifilimi tse tšesaane, tse matla ka boenjiniere ba limolek'hule.

Boitlamo ba ho kopanya: Lifilimi tse etselitsoeng ka ho khetheha libaka tsa polokelo tse ikemetseng.

Moruo o chitja: Litsamaiso tse ntlafetseng tsa ho sebelisoa hape le tse koetsoeng.

Karolo e otlolohileng ea lifilimi, e neng e ikarabella hoo e ka bang karolo ea boraro ho tse 'nè ea lekeno la 'maraka oa lifilimi tsa polyethylene ka 2020, e lebelletsoe ho hola ho CAGR e potlakileng ea 4.6% ho fihlela ka 2030.
