Mawu Oyamba
Kupanga mafilimu opangidwa ndi polyethylene (PE) ndi njira yomwe imagwiritsidwa ntchito kwambiri popanga mafilimu apulasitiki omwe amagwiritsidwa ntchito popaka, ulimi, ndi zomangamanga. Njirayi imaphatikizapo kutulutsa PE yosungunula kudzera mukufa kozungulira, ndikuyiyika mu thovu, ndiyeno kuziziritsa ndikumangirira mufilimu yathyathyathya. Kuchita bwino ndikofunikira pakupanga zotsika mtengo komanso zomaliza zapamwamba. Komabe, zovuta zingapo zimatha kubuka panthawi yopanga, monga kukangana kwakukulu pakati pa zigawo zamafilimu ndi kutsekereza mafilimu, zomwe zingachepetse kwambiri magwiridwe antchito komanso kusokoneza mtundu wazinthu.

Nkhaniyi ifotokoza zaukadaulo wa filimu yowombedwa ndi PE, ikuyang'ana kwambiri aslip yothandiza kwambiri komanso anti-blocking additivendi momwe zimathandizire kuthana ndi zovuta zopanga kuti ziwonjezeke bwino komanso kupititsa patsogolo filimuyo.

PE Blown Film Production Technical Overview and Efficiency Factors

Chidule cha Njira ya Blown Film Extrusion

The kuwombedwa filimu extrusion ndondomeko imayamba ndi kudyetsa PE utomoni pellets mu extruder, kumene amasungunuka ndi homogenized kudzera osakaniza kutentha ndi kukameta ubweya mphamvu. Polima wosungunuka ndiye amakakamizika kupyolera mu kufa kozungulira, kupanga chubu chopitirira. Mpweya umalowetsedwa mkatikati mwa chubuchi, ndikuufukiza kukhala thovu. Kuwiraku kumakokedwa m'mwamba, nthawi imodzi kutambasula filimuyo kumbali zonse za makina (MD) ndi njira yodutsa (TD), njira yotchedwa biaxial orientation. Pamene thovulo likukwera, limazizidwa ndi mphete ya mpweya, zomwe zimapangitsa kuti polima ikhale yonyezimira komanso yolimba. Pomaliza, kuwira utakhazikika ndi kukomoka ndi gulu la nip odzigudubuza ndi bala pa mpukutu. Zofunikira zomwe zimathandizira njirayi ndi monga kutentha kwa kusungunuka, kusiyana kwa kufa, chiŵerengero cha kuphulika (BUR), kutalika kwa mzere wa frost (FLH), ndi kuzizira.

Mfundo Zofunikira Zomwe Zimakhudza Kuchita Mwachangu

Pali zinthu zingapo zomwe zimakhudza mwachindunji kupanga kwamakanema a PE:

• Kayendetsedwe kake: Mlingo wa momwe filimu imapangidwira. Kupititsa patsogolo nthawi zambiri kumatanthauza kuchita bwino kwambiri.

• Ubwino wa Kanema: Izi zikuphatikiza zinthu monga makulidwe a makulidwe, mphamvu zamakina (mphamvu zolimba, kukana misozi, kugunda kwa dart), mawonekedwe a kuwala (chifunga, gloss), ndi mawonekedwe amtunda (coefficient of friction). Kutsika kwabwino kwa filimu kumabweretsa kuchulukirachulukira kwa zinyalala komanso kuchepa kwa magwiridwe antchito.

• Nthawi yopuma: Kuyimitsidwa kosakonzekera chifukwa cha zovuta monga kusweka kwa filimu, kumangidwa kwakufa, kapena kuwonongeka kwa zipangizo. Kuchepetsa nthawi yocheperako ndikofunikira kuti zitheke.

• Kugwiritsa Ntchito Mphamvu: Mphamvu zomwe zimafunika kusungunula polima, kugwiritsa ntchito chotulutsa, ndi makina oziziritsira mphamvu. Kuchepetsa kugwiritsa ntchito mphamvu kumapangitsa kuti ntchito zonse ziziyenda bwino komanso zimachepetsa ndalama zogwirira ntchito.

• Kugwiritsa Ntchito Zowonongeka: Kugwiritsa ntchito bwino kwa PE resin ndi zowonjezera, kuchepetsa zinyalala.

Mavuto Odziwika Pakupanga Mafilimu a PE Blown

Ngakhale kupita patsogolo kwaukadaulo, kupanga mafilimu a PE kumakumana ndi zovuta zingapo zomwe zingalepheretse kuchita bwino:

• Kutsekereza Mafilimu: Kumamatira kosayenera pakati pa zigawo za filimu, kaya mu mpukutu kapena panthawi yokonzekera. Izi zitha kubweretsa zovuta pakumasula, kuchulukirachulukira, komanso kuchedwa kupanga.

• High Coefficient of Friction (COF): Kukangana kwakukulu pamtunda wa filimu kungayambitse mavuto panthawi yokhotakhota, kumasula, ndi kutembenuza ntchito, zomwe zimatsogolera kumamatira, kung'ambika, ndi kuchepetsa kuthamanga.

• Die Build-up: Kuchuluka kwa ma polima owonongeka kapena zowonjezera kuzungulira kufa, zomwe zimatsogolera ku mikwingwirima, ma gels, ndi zolakwika zamakanema.

• Sungunulani Fracture: Zosasintha pa filimuyi chifukwa cha kupsinjika kwakukulu kwa kukameta ubweya mu kufa, zomwe zimapangitsa kuti pakhale mawonekedwe okhwima kapena a wavy.

• Gels ndi Nsomba: Tinthu tating'onoting'ono ta polima kapena zonyansa zomwe zimawoneka ngati zazing'ono, zowonekera kapena zowoneka bwino mufilimuyi.

Mavutowa nthawi zambiri amayenera kuchedwetsa njira yopangira zinthu, kuchulukitsa kuwonongeka kwa zinthu, komanso kumafuna kulowererapo kwa ogwira ntchito, zomwe zimachepetsa mphamvu zonse. Kugwiritsa ntchito mwanzeru zowonjezera, makamaka ma slip ndi anti-blocking agents, kumagwira ntchito yofunika kwambiri pochepetsa zovutazi ndikuwongolera njira zopangira.

Njira Zothetsera Mavuto Pakupanga Mafilimu Apulasitiki

Kuyambitsa SILIMER Series Non-precipitating Super Slip & Anti-blocking Additives: Njira imodzi Yamavuto Awiri

Pofuna kuthana ndi zovutazi, SILIKE yapanga SILIMER 5064 MB2 masterbatch, aThandizo lotsika mtengo lazinthu zambirizomwe zimaphatikiza magwiridwe antchito a slip ndi anti-blocking munjira imodzi. Popereka zonse ziwiri mu chinthu chimodzi, zimachotsa kufunikira kosamalira ndikuwonjezera zowonjezera zingapo.

SILIKE Slip & Antiblock Additive Limbikitsani Bwino Lanu Lopanga Mafilimu Apulasitiki

Ubwino Wachikulu Wopanda Kusamuka / Anti-Blocking Additive SILIMER 5064MB2 pafilimu ya PE

1. Kuwongolera Mafilimu Owongolera ndi Kusinthika

Mosiyana ndi ma slip agents wamba,SILIMER 5064 MB2 ndi masterbatc yopanda mvulah yokhala ndi zowonjezera zoletsa kutsekereza. Imawongolera kasamalidwe ka filimu posindikiza, kupukuta, ndi kupanga matumba popanda kusamukira pamwamba kapena kukhudza khalidwe la kusindikiza, kusindikiza kutentha, zitsulo, kumveka bwino, kapena ntchito zotchinga.

2. Kuchulukitsa Kupanga Mwachangu ndi Kuthamanga

Imachepetsa kugundana kwapakati (COF), kupangitsa kuti mizere ichuluke kwambiri, kumasuka bwino, komanso kutulutsa bwino ndi kutembenuza. Kukangana kocheperako kumachepetsa kupsinjika kwa makina, kumakulitsa moyo wa zida, kumadula zosoweka, ndikuwonjezera kutulutsa ndi kutsika pang'ono komanso kuwononga.

3. Kuletsa Kuletsa

Imalepheretsa zigawo za filimu kuti zisamamatirane, kuwonetsetsa kumasuka komanso kukonza. Amachepetsa kumamatira pakati pa zigawo, kuchepetsa kutsekereza, kung'ambika, mitengo yazinyalala, ndi zinyalala zakuthupi.
4. Ubwino Wowonjezera Wazinthu ndi Zokongola

Silicone Slip Additive SILIMER 5064 MB2 Imachotsa mpweya wa ufa ndi kuipitsidwa pamwamba, kutulutsa mafilimu osalala, ofananirako kwinaku akusunga magwiridwe antchito komanso kukhulupirika kwazinthu.

Opanga mafilimu a PE, kodi mukulimbana ndi kukangana kwakukulu, kutsekereza mafilimu, komanso nthawi yotsika mtengo pakupanga kwanu? Yang'anirani ntchito zanu, chepetsani zopanda pake, ndikuwonjezera mphamvu -SILIMER 5064 MB2ndiye yankho la zonse mu chimodzi. Lumikizanani ndi SILIKE lero kuti mufunse zitsanzo zoyeserera ndikuwona kusiyana kwake.

SILIKE imapereka mayankho osiyanasiyana. Kaya mukufuna zowonjezera zamafilimu apulasitiki, masilipi opangira makanema a polyethylene, kapena othandizira osasuntha osasuntha, tili ndi zinthu zoyenera pazosowa zanu. Zathuslip osasuntha ndi zowonjezera zotsutsana ndi blockadapangidwa mwapadera kuti apititse patsogolo magwiridwe antchito ndikuwongolera njira yanu yopangira.
