Mukufuna kukonza bwino mzere wanu wolongedza kapena kukonza magwiridwe antchito a nyumba zopangidwa ndi laminated? Buku lothandizali likufotokoza mfundo zofunika, kusankha zinthu, njira zogwirira ntchito, ndi njira zothetsera mavuto pakuphimba zinthu (komwe kumadziwikanso kuti lamination) — ukadaulo womwe umagwiritsidwa ntchito kwambiri m'magawo olongedza, azachipatala, magalimoto, ndi mafakitale.

Kodi Lamination (Extrusion Coating) ndi Chiyani Ndipo Imagwira Ntchito Bwanji?

Kupaka utoto, kapena kupopera utoto, ndi njira yomwe imaphatikizapo kupopera utoto wosungunuka wa pulasitiki (nthawi zambiri polyethylene, PE) mofanana pa zinthu monga pepala, nsalu, zinthu zosalukidwa, kapena zojambulazo za aluminiyamu. Pogwiritsa ntchito chipangizo chopopera utoto, pulasitikiyo imasungunuka, kuphimbidwa, ndikuziziritsidwa kuti ipange kapangidwe kophatikizana.

Mfundo yaikulu ndikugwiritsa ntchito kusinthasintha kwa pulasitiki yosungunuka kutentha kwambiri kuti igwirizane bwino ndi substrate, potero kuwonjezera zinthu zotchinga, kutseka kutentha, komanso kulimba kwa maziko.

Njira Zofunikira Zopangira Lamination

1. Kukonzekera Zinthu Zopangira: Sankhani ma pulasitiki oyenera (monga PE, PP, PLA) ndi zinthu zina (monga pepala losaphika, nsalu yosalukidwa).

2. Kusungunula ndi Kutulutsa Mapulasitiki: Ma pellets apulasitiki amalowetsedwa mu chotulutsira, komwe amasungunuka kukhala madzi okhuthala kutentha kwambiri. Kenako pulasitiki yosungunuka imatulutsidwa kudzera mu T-die kuti ipange kusungunuka kofanana ndi filimu.

3. Kuphimba ndi Kusakaniza: Filimu yosungunuka ya pulasitiki imakutidwa bwino pamwamba pa substrate yomwe isanatuluke pansi pa mphamvu yolamulira. Pamalo ophimba, pulasitiki yosungunuka ndi substrate zimagwirizanitsidwa mwamphamvu pogwiritsa ntchito makina opondereza.

4. Kuziziritsa ndi Kukhazikitsa: Zinthu zosakanikirana zimadutsa mwachangu m'ma rollers ozizira, zomwe zimathandiza kuti pulasitiki yosungunuka izizire mwachangu ndikulimba, ndikupanga filimu yapulasitiki yolimba.

5. Kupindika: Chopangidwa ndi zinthu zoziziritsidwa ndi zokhazikika zimakulungidwa m'ma roll kuti zigwiritsidwe ntchito pambuyo pake.

6. Njira Zosankha: Nthawi zina, kuti pakhale kulimba kwa laminated kapena kuwonjezera mawonekedwe a pamwamba, substrate ikhoza kuchiritsidwa ndi corona isanayambe kupakidwa.

Buku Lotsogolera Kusankha Substrate ndi Pulasitiki la Extrusion Coating kapena Lamination

Zipangizo zomwe zimagwiritsidwa ntchito popanga lamination zimaphatikizapo zinthu monga ma substrates ndi zinthu zopangira laminating (mapulasitiki).

1. Ma substrate

2. Zipangizo Zopaka Mafuta (Mapulasitiki)

• Polyethylene (PE)

LDPE: Yosinthasintha bwino, malo osungunuka pang'ono, yoyenera kupukuta mapepala.

LLDPE: Mphamvu yolimba kwambiri komanso kukana kubowola, nthawi zambiri imasakanizidwa ndi LDPE.

HDPE: Imapereka kulimba kwambiri komanso magwiridwe antchito otchinga, koma ndi yovuta kwambiri kuikonza.

• Polypropylene (PP)

Kukana kutentha ndi kulimba bwino kuposa PE. Ndikwabwino kugwiritsa ntchito poyeretsa thupi kutentha kwambiri.

• Mapulasitiki Otha Kuwonongeka

PLA: Yowonekera bwino, yowola, koma yolimba kwambiri pa kutentha.

PBS/PBAT: Yosinthika komanso yokonzedwa; yoyenera njira zosungiramo zinthu zokhazikika.

• Ma polima apadera

EVOH: Chotchinga chabwino kwambiri cha mpweya, chomwe nthawi zambiri chimagwiritsidwa ntchito ngati gawo lapakati mu phukusi la chakudya.

Ma Ionomers: Kuwala kwambiri, kukana mafuta, kutseka bwino kwambiri.

Mavuto ndi Mayankho Ofala mu Extrusion Coating ndi Lamination:Buku Lothandiza Lothetsera Mavuto

1. Nkhani Zokhudza Kumatira/Kuletsa

Zifukwa: Kuziziritsa kosakwanira, kugwedezeka kwambiri kwa mpweya, kufalikira kosakwanira kapena kosagwirizana kwa mankhwala oletsa kutsekeka, kutentha kwambiri, ndi chinyezi.

Mayankho: Kuchepetsa kutentha kwa roller yozizira, kuwonjezera nthawi yozizira; kuchepetsa kupsinjika koyenera; kuwonjezera kapena kukonza kuchuluka ndi kufalikira kwa zinthu zoletsa kutsekeka (monga erucamide, oleamide, silica, SILlKE SILIMER series super slip ndi anti-blocking masterbatch); kusintha kutentha ndi chinyezi m'malo opangira.

Tikuyambitsa SILIKE SILIMER Series: High-Performance Slip and Anti-Blocking Masterbatch ya Mafilimu Amitundu Yosiyanasiyana a Pulasitiki ndi Ma Polima Osinthidwa.

Ubwino Waukulu: Zotchingira ndi zoletsa kutsekeka kwa Mafilimu a Polyethylene

•Kutsegula bwino kwa filimu ndi kutsetsereka

• Kukhazikika kwa nthawi yayitali pansi pa kutentha kwambiri

• Palibe mvula kapena ufa (“palibe maluwa”)

• Palibe vuto lililonse pa kusindikiza, kutseka kutentha, kapena kuyika lamination

• Zimathandiza kuti madzi azisungunuka bwino komanso kuti utoto, zodzaza, ndi zowonjezera zomwe zimagwira ntchito bwino zifalikire bwino.

Ndemanga za Makasitomala - Mayankho a Extrusion Coating kapena Lamination Applications:
Opanga mafilimu apulasitiki omwe amagwiritsa ntchito njira zophikira zopaka utoto ndi zotulutsa utoto amanena kuti mankhwala otsekemera a SILIMER amathetsa mavuto omatira milomo ndipo amawongolera kwambiri magwiridwe antchito a zophikira zochokera ku PE.

2. Kusakwanira kwa Peel Strength (Delamination):

Zifukwa: Mphamvu yochepa pamwamba pa nthaka, kusakwanira kwa chithandizo cha korona, kutentha kochepa kwambiri kwa extrusion, kupanikizika kosakwanira kwa chophimba, komanso kusagwirizana pakati pa pulasitiki ndi nthaka.

Mayankho: Sinthani mphamvu ya mankhwala a korona pa substrate; onjezerani kutentha koyenera kuti muwonjezere chinyezi cha kusungunuka ku substrate; onjezerani mphamvu ya kupaka utoto; sankhani zinthu zomatira zomwe zimagwirizana bwino ndi substrate, kapena onjezerani zinthu zolumikizira.

3. Zolakwika pamwamba (monga madontho, maso a nsomba, kapangidwe ka khungu la lalanje):

Zifukwa: Zodetsa, zinthu zosasungunuka, chinyezi mu zipangizo zopangira pulasitiki; kusayera bwino kwa dizilo; kutentha kosakhazikika kwa extrusion kapena kupanikizika; kuzizira kosagwirizana.

Mayankho: Gwiritsani ntchito zipangizo zopangira pulasitiki zouma komanso zapamwamba; yeretsani nthawi zonse chotsukira ndi chotulutsira madzi; konzani njira zotulutsira madzi ndi zoziziritsira.

4. Kukhuthala Kosafanana:

Zifukwa: Kutentha kosagwirizana kwa die, kusintha kosayenera kwa die lip gap, screw extruder screw yosweka, makulidwe osafanana a substrate.

Mayankho: Yang'anirani kutentha kwa die molondola; sinthani kusiyana kwa milomo ya die; sungani nthawi zonse chotulutsira; onetsetsani kuti substrate ndi yabwino.

5. Kusatseka Kutentha:

Zifukwa: Kusakwanira makulidwe a laminated layer, kutentha kosayenera kotseka kutentha, kusankha kosayenera kwa laminating slayer.

Mayankho: Onjezani makulidwe oyenera a laminated; konzani kutentha kotseka kutentha, kupanikizika, ndi nthawi; sankhani zipangizo zotchingira kutentha zomwe zili ndi mphamvu zabwino zotseka kutentha (monga LDPE, LLDPE).

Mukufuna Thandizo Kukonza Mzere Wanu Wopaka Lamination Kapena Kusankha WoyeneraZowonjezera pa mafilimu apulasitiki ndi ma CD osinthasintha?
Lumikizanani ndi gulu lathu laukadaulo kapena fufuzani njira zowonjezera za SILIKE zopangidwa ndi silicone zomwe zapangidwira osinthira ma CD.

Mndandanda wathu wa SILIMER umapereka magwiridwe antchito okhazikika komanso oletsa kutsekeka, kukulitsa ubwino wa malonda, kuchepetsa zolakwika pamwamba, komanso kukulitsa magwiridwe antchito a lamination.

Lankhulani bwino ndi mavuto monga kutayika kwa ufa woyera, kusamuka kwa mpweya, ndi mawonekedwe osasinthasintha a filimu.

Monga wopanga wodalirika wa zowonjezera za pulasitiki, SILIKE imapereka njira zambiri zochepetsera kutsika ndi kutsekeka zomwe zimapangidwa kuti ziwongolere kukonza ndi magwiridwe antchito a mafilimu okhala ndi polyolefin. Mndandanda wathu wazinthu umaphatikizapo zowonjezera zochepetsera kutsekeka, ma masterbatches otsetsereka ndi oletsa kutsekeka, zinthu zochepetsera kutsekeka zochokera ku silicone, zowonjezera kutentha kwambiri komanso zokhazikika, zokhazikika, zothandizira njira zambiri, ndi zowonjezera za polyolefin. Mayankho awa ndi abwino kwambiri pamapaketi osinthika, kuthandiza opanga kupeza mawonekedwe abwino pamwamba, kuchepetsa kutsekeka kwa filimu, komanso kukonza bwino ntchito yopanga.

Lumikizanani nafe paamy.wang@silike.cn kuti mupeze chowonjezera choyenera kwambiri cha mafilimu anu apulasitiki komanso zosowa zanu zopangira ma CD osinthika.
