Mukuyang'ana kukhathamiritsa mzere wanu woyikapo kapena kukonza magwiridwe antchito a mapangidwe a laminated? Buku lothandizali likuwunika mfundo zofunika, kusankha zinthu, masitepe okonza, ndi njira zothetsera mavuto mu zokutira zakunja (zomwe zimadziwikanso kuti lamination) - ukadaulo womwe umagwiritsidwa ntchito kwambiri pakuyika, zamankhwala, zamagalimoto, ndi mafakitale.

Kodi Lamination (Extrusion Coating) Ndi Chiyani Ndipo Imagwira Ntchito Motani?

Lamination, kapena extrusion zokutira, ndi njira yomwe imaphatikizapo kupaka pulasitiki wosungunuka (nthawi zambiri polyethylene, PE) mofanana pamagulu monga mapepala, nsalu, zosawomba, kapena zojambulazo za aluminiyamu. Pogwiritsa ntchito chipangizo cha extrusion, pulasitiki imasungunuka, yokutidwa, ndi kuzizira kuti ikhale yopangidwa ndi gulu.

Mfundo yaikulu ndikugwiritsa ntchito madzi a pulasitiki osungunuka pa kutentha kwakukulu kuti agwirizane kwambiri ndi gawo lapansi, potero kuwonjezera zotchinga, kutentha-kutsekedwa, ndi kulimba kwa zinthu zoyambira.

Key Lamination Njira Masitepe

1. Kukonzekera Kwazinthu Zopangira: Sankhani mapepala apulasitiki oyenera (mwachitsanzo, PE, PP, PLA) ndi magawo (mwachitsanzo, mapepala a virgin, nsalu zosalukidwa).

2. Kusungunuka kwa Pulasitiki ndi Kutulutsa: Mapulasitiki apulasitiki amadyetsedwa mu extruder, kumene amasungunuka mumadzimadzi a viscous pa kutentha kwakukulu. Pulasitiki yosungunukayo imatulutsidwa kudzera mu T-die kuti ipangike ngati filimu yosungunuka.

3. Kupaka ndi Kuphatikizira: Filimu yapulasitiki yosungunuka imakutidwa ndendende pamwamba pa gawo lapansi lomwe lisanavulazidwe pansi pazovuta. Pamalo opaka, pulasitiki yosungunuka ndi gawo lapansi zimamangirizidwa mwamphamvu pamodzi pansi pa zochita za odzigudubuza.

4. Kuziziritsa ndi Kukhazikitsa: Zomwe zimapangidwira zimadutsa mofulumira pazitsulo zoziziritsa kuzizira, zomwe zimalola kuti pulasitiki yosungunuka ikhale yozizira komanso yolimba, kupanga filimu yolimba ya pulasitiki.

5. Kumangirira: Zinthu zoziziritsidwa ndi zoyikidwa zopangidwa ndi laminated zimayikidwa mumipukutu kuti zisinthidwe ndikuzigwiritsa ntchito.

6. Njira Zosankhira: Nthawi zina, kuti muzitha kumamatira kwa wosanjikiza wa laminated kapena kukulitsa mawonekedwe apamwamba, gawo lapansi limatha kuthandizidwa ndi corona musanakutidwe.

Gawo Lapansi ndi Pulasitiki Kusankha Maupangiri a Extrusion Coating kapena Lamination

Zida zomwe zimakhudzidwa ndi njira yopangira lamination makamaka zimaphatikizapo magawo apansi ndi zipangizo zopangira laminating (pulasitiki).

1. Magawo

2. Zida Zoyatsira (Plastiki)

• Polyethylene (PE)

LDPE: Kusinthasintha kwabwino, malo osungunuka otsika, abwino pamapepala.

LLDPE: Kulimba kwamphamvu kwambiri komanso kukana nkhonya, nthawi zambiri kumasakanikirana ndi LDPE.

HDPE: Imakhala yolimba kwambiri komanso yotchinga, koma ndiyovuta kuyikonza.

• Polypropylene (PP)

Kukana kwabwino kwamafuta komanso kulimba kuposa PE. Ndibwino kugwiritsa ntchito zoletsa kutentha kwambiri.

• Mapulasitiki Osawonongeka

PLA: Yowonekera, yosasinthika, koma yochepa pakukana kutentha.

PBS/PBAT: Yosinthika komanso yosinthika; oyenera ma phukusi okhazikika mayankho.

• Ma polima apadera

EVOH: Chotchinga chabwino kwambiri cha okosijeni, chomwe nthawi zambiri chimagwiritsidwa ntchito ngati gawo lapakati pamapaketi azakudya.

Ionomers: Kumveka bwino, kukana mafuta, kutsekedwa bwino kwambiri.

Mavuto Wamba ndi Mayankho mu Extrusion Coating and Lamination:Buku Lothandizira Kuthetsa Mavuto

1. Kumamatira / Kutsekereza Nkhani

Zomwe zimayambitsa: Kuzizira kosakwanira, kugwedezeka kwa mafunde kwambiri, kusakwanira kapena kubalalitsidwa kosafanana kwa anti-blocking agent, kutentha kwakukulu kozungulira, ndi chinyezi.

Mayankho: M'munsi yozizira wodzigudubuza kutentha, kuwonjezera kuzirala nthawi; moyenera kuchepetsa kukangana kokhotakhota; onjezani kapena kukhathamiritsa kuchuluka ndi kubalalitsidwa kwa anti-blocking agents (mwachitsanzo, erucamide, oleamide, silika, SILlKE SILIMER super slip ndi anti-blocking masterbatch); kusintha kutentha ndi chinyezi m'malo opangira zinthu.

Kuyambitsa SILIKE SILIMER Series: High-Performance Slip and Anti-Blocking Masterbatch ya Makanema Osiyanasiyana a Pulasitiki ndi Ma Polymers Osinthidwa.

Ubwino Wofunika Kwambiri Slip ndi anti-blocking agents for Polyethylene Films

•Kupititsa patsogolo slip ndi kutsegula filimu

• Kukhazikika kwa nthawi yayitali pansi pa kutentha kwakukulu

• Palibe mvula kapena ufa ("palibe pachimake")

• Palibe vuto lililonse pakusindikiza, kusindikiza kutentha, kapena lamination

• Imapititsa patsogolo kusungunuka kwamadzi ndi kubalalika kwa ma pigment, zodzaza, ndi zowonjezera zomwe zimagwira ntchito mkati mwa utomoni.

Ndemanga ya Makasitomala - Kuphimba kwa Extrusion kapena Lamination Applications Solutions:
Opanga mafilimu apulasitiki omwe amagwiritsa ntchito ma lamination ndi ma extrusion zokutira amati SILIMER slip ndi anti-blocking agents amathetsa bwino nkhani zomata milomo yakufa ndikuwongolera kwambiri kukonza bwino kwa zokutira zochokera ku PE.

2. Kusakwanira kwa Peel Mphamvu (Delamination):

Zomwe zimayambitsa: Mphamvu yapansi panthaka yotsika, chithandizo chosakwanira cha corona, kutentha kwapang'onopang'ono kutulutsa, kusakwanira kwa zokutira, komanso kusagwirizana pakati pa pulasitiki ndi gawo lapansi.

Yankho: Sinthani mphamvu ya chithandizo cha corona pa gawo lapansi; moyenerera onjezerani kutentha kwa extrusion kuti muwonjezere kusungunuka kwa kusungunuka kwa gawo lapansi; kuwonjezera ❖ kuyanika kuthamanga; kusankha Laminating Zida zogwirizana bwino ndi gawo lapansi, kapena onjezani othandizira.

3. Zowonongeka Pamwamba (mwachitsanzo, madontho, maso a nsomba, mawonekedwe a peel lalanje):

Zomwe zimayambitsa: Zonyansa, zinthu zosasungunuka, chinyezi muzinthu zapulasitiki; kusowa kwaukhondo wakufa; kutentha kosakhazikika kwa extrusion kapena kuthamanga; kuzizira kosiyana.

Mayankho: Gwiritsani ntchito zida zapamwamba, zowuma zamapulasitiki; nthawi zonse kuyeretsa ufa ndi extruder; kukhathamiritsa extrusion ndi kuzirala magawo.

4. Kunenepa Kwambiri:

Zomwe zimayambitsa: Kutentha kosagwirizana ndi kufa, kusintha kosayenera kwa milomo yakufa, zomangira za extruder, makulidwe a gawo lapansi.

Njira zothetsera kutentha kwa kutentha; sinthani kusiyana kwa milomo yakufa; nthawi zonse kusunga extruder; kuonetsetsa kuti gawo lapansi labwino.

5. Kusatsekeka kwa Kutentha Kwambiri:

Zimayambitsa: osakwanira laminated wosanjikiza makulidwe, molakwika kutentha-kusindikiza kutentha, kusankha molakwika laminating zakuthupi.

Zothetsera: Moyenera kuonjezera makulidwe a laminated; kukhathamiritsa kutentha-kusindikiza kutentha, kuthamanga, ndi nthawi; kusankha zipangizo laminating ndi zinthu bwino kutentha-sealable (mwachitsanzo, LDPE, LLDPE).

Mufunika Thandizo Kukulitsa Mzere Wanu Wopangira Lamination kapena Kusankha ChabwinoZowonjezera mafilimu a Pulasitiki ndi zolembera zosinthika?
Lumikizanani ndi gulu lathu laukadaulo kapena onani zowonjezera za SILIKE zochokera ku silikoni zomwe zimapangidwira zosinthira ma CD.

Mndandanda wathu wa SILIMER umapereka magwiridwe antchito osatha komanso oletsa kutsekereza, kupititsa patsogolo mtundu wazinthu, kuchepetsa kuwonongeka kwapamtunda, komanso kukulitsa luso lapamwamba.

Sanzikanani ndi zinthu monga mvula ya ufa woyera, kusamuka, ndi kusagwirizana kwa mafilimu.

Monga opanga odalirika opanga zowonjezera mafilimu apulasitiki, SILIKE imapereka njira zambiri zotsitsimula zosagwetsa komanso zoletsa kutsekereza zomwe zimapangidwa kuti zithandizire kukonza ndi kuwongolera mafilimu opangidwa ndi polyolefin. Zogulitsa zathu zimaphatikizapo zowonjezera zoletsa kutsekereza, ma slip ndi anti-block masterbatches, ma silicone-based slip agents, kutentha kwambiri komanso kukhazikika, zowonjezera zokhala ndi nthawi yayitali, zothandizira njira zambiri, ndi zowonjezera mafilimu a polyolefin. Mayankho awa ndi abwino pamapaketi osinthika, kuthandiza opanga kuti akwaniritse mawonekedwe apamwamba, kuchepetsa kutsekereza kwamakanema, komanso kupanga bwino.
