Kutsvaga kukwirisa mutsara wako wekurongedza kana kuvandudza mashandiro emalaminated zvimiro? Iri gwara rinoshanda rinoongorora misimboti yakakosha, kusarudzwa kwezvinhu, nhanho dzekugadzirisa, uye nzira dzekugadzirisa matambudziko mu extrusion coating (inozivikanwawo selamination) - tekinoroji inoshandiswa zvakanyanya mumapaketi, ekurapa, emotokari, uye maindasitiri.
Chii chinonzi Lamination (Extrusion Coating) uye Inoshanda Sei?
Lamination, kana extrusion coating, inzira inosanganisira kupfekedza purasitiki yakanyungudutswa (kazhinji kacho polyethylene, PE) zvakafanana pamasubstrates senge bepa, machira, asiri-kurukwa, kana aluminium foil. Uchishandisa mudziyo weextrusion, purasitiki inonyungudutswa, yakaputirwa, uye yakatonhodzwa kuti iite chimiro chakaumbwa.
Musimboti wemusimboti ndeye kushandisa kunyungudutswa kwepurasitiki yakanyungudutswa pakupisa kwepamusoro kuti uwane kubatana kwakasimba neiyo substrate, nekudaro kuwedzera zvipingamupinyi zvivakwa, kupisa-kuvharwa, uye kusimba kune iyo base zvinhu.
Key Lamination Process Matanho
1. Raw Material Gadziriro: Sarudza mapeti epurasitiki akakodzera (eg, PE, PP, PLA) uye substrates (semuenzaniso, mhandara bepa, jira risiri rakarukwa).
2. Kunyunguduka kwePlastiki uye Extrusion: Plastiki pellets inodyiswa muextruder, iyo inonyungudutswa muine viscous fluid pakupisa kwakanyanya. Plastiki yakanyungudutswa inozoburitswa kuburikidza neT-die kuita yunifomu yefirimu-yakanyungudika.
3. Coating and Compounding: Iyo firimu yepurasitiki yakanyungudutswa yakanyatsonamirwa pamusoro peiyo pre-unwound substrate pasi pesimba rekumanikidza. Panzvimbo yekuputira, ipurasitiki yakanyungudutswa uye substrate yakanyatsobatanidzwa pamwe chete pasi pechiito chekumanikidza rollers.
4. Kutonhodza uye Kugadzika: Zvinhu zvakasanganiswa zvinokurumidza kupfuura kuburikidza nekutonhodza rollers, zvichibvumira purasitiki yakanyungudutswa kuti ikurumidze kutonhora uye kusimba, ichiita firimu rakasimba repurasitiki.
5. Winding: Iyo yakatonhodzwa uye yakagadzika laminated composite zvinhu inoiswa mumipumburu kuitira kunotevera kugadzirisa uye kushandiswa.
6. Zvingasarudzwa Matanho: Mune zvimwe zviitiko, kuti uvandudze kunamatira kwelaminated layer kana kuwedzera pamusoro pezvinhu, iyo substrate inogona kuitiswa corona kurapwa isati yapfekedzwa.
Substrate uye Plastic Sarudzo Yekutungamira yeExtrusion Coating kana Lamination
Izvo zvinhu zvinosanganisirwa mukuita lamination zvinonyanya zvinosanganisira substrates uye laminating zvinhu (mapurasitiki).
1. Substrates
| Substrate Type | Key Applications | Hunhu Hunokosha |
| Pepa / Pepabhodhi | Makapu, mbiya, kurongedza chikafu, mabhegi emapepa | Inokanganisa kunaka kwekubatanidza zvinoenderana nefiber chimiro uye kutsetseka kwepamusoro |
| Mucheka usina kurukwa | Zvipfeko zvekurapa, zvigadzirwa zvehutsanana, zvemukati zvemotokari | Porous uye yakapfava, inoda akagadzirirwa bonding parameters |
| Aluminium Foil | Chikafu, pharma kurongedza | Inopa zvakanakisa zvipingamupinyi zvivakwa; lamination inowedzera simba remagetsi |
| Mafirimu epurasitiki (semuenzaniso, BOPP, PET, CPP) | Multi-layer barriers mafirimu | Inoshandiswa kusanganisa akawanda epurasitiki akaturikidzana kuti awedzere kushanda |
2. Laminating Materials (Plastiki)
• Polyethylene (PE)
LDPE: Yakanakisa kuchinjika, yakaderera kunyungudika, yakanakira bepa lamination.
LLDPE: Yakanyanya kusimba simba uye puncture kuramba, kazhinji inosanganiswa neLDPE.
HDPE: Inopa kuomarara kwepamusoro uye kuvharidzira kuita, asi yakanyanya kuoma kugadzirisa.
• Polypropylene (PP)
Zvirinani kupisa kupisa uye kusimba pane PE. Yakanakira kutonhora kwepamusoro-tembiricha maapplication.
• Biodegradable Plastics
PLA: Yakajeka, biodegradable, asi inogumira mukupisa kupisa.
PBS/PBAT: Inoshanduka uye inogadziriswa; yakakodzera kune inogadziriswa yekurongedza mhinduro.
• Specialty Polymers
EVOH: Yakanakisa okisijeni chipingamupinyi, chinowanzo shandiswa seyepakati layer mukurongedza chikafu.
Ionomers: Kujeka kwepamusoro, kuramba kwemafuta, kuvharika kwakanyanya.
Matambudziko Akajairika uye Mhinduro muExtrusion Coating uye Lamination:A Inoshanda Troubleshooting Guide
1. Adhesion / Blocking Issues
Zvikonzero: Kusakwana kutonhora, kunyanya kupeta mhepo, kusakwana kana kusaenzana kupararira kweanti-blocking agent, tembiricha yepamusoro, uye hunyoro.
Solutions: Lower kutonhora roller tembiricha, kuwedzera kutonhora nguva; zvakakodzera kuderedza mhepo inoputika; kuwedzera kana kukwidziridza huwandu uye kupararira kweanopesana-kuvharira vamiririri (semuenzaniso, erucamide, oleamide, silica, SILlKE SILIMER series super slip uye anti-blocking masterbatch); kunatsa ambient tembiricha uye humidity munzvimbo yekugadzira.
Kuunza SILIKE SILIMER Series: Yepamusoro-Kuita Slip uye Anti-Kuvharira Masterbatch yeakasiyana ePlastiki Mafirimu uye Akagadziridzwa Polymers.
Key Benefits Slip uye anti-blocking agents ePolyethylene Films
•Yakavandudzwa slip uye firimu rekuvhura kuita
• Kugadzikana kwenguva refu pasi pemamiriro ekupisa kwepamusoro
• Hapana kunaya kana kuita upfu (“hapana kutumbuka” mhedzisiro)
• Hapana kukanganisa kudhinda, kuvhara kupisa, kana lamination
• Inovandudza kunyunguduka kuyerera uye kupararira kwemavara, mafirita, uye anoshanda ekuwedzera mukati meiyo resin system.
Mutengi Feedback - Extrusion Coating kana lamination Applications Solutions:
Vagadziri vemafirimu epurasitiki vanoshandisa lamination uye extrusion coating process vanotaura kuti SILIMER inotsvedza uye anti-blocking agents zvinogadzirisa zvinogadzirisa nyaya dzekunamatira miromo uye inovandudza zvakanyanya mashandiro ekugadzirisa muPE-based coatings.
2. Kusakwana Peel Simba (Delamination):
Zvinokonzera: Yakaderera substrate pamusoro pesimba, kusakwana kurapwa kwekorona, yakanyanya kuderera tembiricha yekuwedzeredza, kusakwana kwekumanikidza yekupfeka, uye kusawirirana pakati pepurasitiki ne substrate.
Mhinduro: Kuvandudza maitiro ekurapa kwekorona pane substrate; zvakakodzera kuwedzera extrusion tembiricha kuti uwedzere kunyorova kwekunyunguduka kune substrate; kuwedzera coating pressure; sarudza laminating Zvishandiso zvine kuenderana zviri nani neiyo substrate, kana kuwedzera coupling agents.
3. Kukanganisika kwePamusoro (semuenzaniso, makwapa, maziso ehove, kuumbwa kweganda reorenji):
Zvinokonzera: Kusachena, zvinhu zvisina kunyunguduka, mwando mupurasitiki mbishi zvinhu; kusachena kusina kunaka kwefa; kusagadzikana extrusion tembiricha kana kumanikidzwa; kutonhora zvisina kuenzana.
Solutions: Shandisa yakakwirira-mhando, yakaoma epurasitiki mbishi zvinhu; nguva dzose kuchenesa die uye extruder; optimize extrusion uye kutonhora paramita.
4. Hukobvu Husina Kuenzana:
Zvinokonzera: Kusaenzana kufa tembiricha, kurongeka kwakashata kwefa lip gap, yakapfekwa extruder screw, kusaenzana substrate ukobvu.
Solutions: Nyatsodzora kufa tembiricha; gadzirisa kufa lip gap; nguva dzose chengetedza extruder; chengetedza hutano hwe substrate.
5. Husina Kupisa-Kuvharika:
Zvikonzero: Kusakwana laminated layer gobvu, kupisa-kuvharisa tembiricha isina kufanira, kusarudzwa kwakashata kwelaminating zvinhu.
Solutions: Zvakakodzera kuwedzera laminated ukobvu; optimize tembiricha yekuvhara-kupisa, kudzvanywa, uye nguva; sarudza laminating zvinhu zviri nani kupisa-sealable zvivakwa (semuenzaniso, LDPE, LLDPE).
Unoda Rubatsiro Kukwirisa Yako Lamination Line kana Kusarudza Iko KurudyiKuwedzera kwePurasitiki mafirimu uye Flexible kurongedza?
Batanidza nechikwata chedu chehunyanzvi kana ongorora SILIKE's silicone-yakavakirwa yekuwedzera mhinduro dzakagadzirirwa ekurongedza ekushandura.
Yedu SILIMER Series inopa inogara inotsvedza uye anti-kuvharira kuita, inosimudzira chigadzirwa mhando, kuderedza kuremara kwepasi, uye kuwedzera lamination kushanda zvakanaka.
Taura zvakanaka kune nyaya dzakaita semvura yehupfu chena, kutama, uye zvimiro zvemufirimu zvisingaenderane.
Semugadziri anovimbika wezvekuwedzera kwemafirimu epurasitiki, SILIKE inopa huwandu hwakakwana hwekutsvedza kwepasirese uye anti-blocking mhinduro dzakagadzirirwa kuvandudza mashandiro uye kuita kwemafirimu ane polyolefin. Chigadzirwa chedu chepodfolio chinosanganisira anti-blocking additives, slip uye anti-block masterbatches, silicone-based slip agents, yakakwirira-tembiricha uye yakagadzikana, inogara kwenguva refu inotsvedza additives, multifunctional process aids, uye polyolefin film additives. Idzi mhinduro dzakanakira kuchinjika kurongedza maapplication, kubatsira vagadziri kuwana yakakwidziridzwa yemhando yepamusoro, kuderedzwa kuvharika kwemafirimu, uye nekuvandudza kugadzirwa kwakanaka.
Tibate paamy.wang@silike.cn kuti uwane iyo yakakwana yekuwedzera yemafirimu ako epurasitiki uye inochinjika yekugadzira yekurongedza zvinodiwa.
