Kupanga mafilimu opangidwa ndi polyethylene (PE) ndi njira yogwiritsidwa ntchito kwambiri popanga mafilimu apulasitiki omwe amagwiritsidwa ntchito popaka, ulimi, ndi zomangamanga. Njirayi imaphatikizapo kutulutsa PE yosungunuka kudzera mu die yozungulira, kuipitsa kukhala thovu, kenako kuziziritsa ndikuyikulunga kukhala filimu yathyathyathya. Kugwiritsa ntchito bwino ndikofunikira kwambiri popanga zinthu zotsika mtengo komanso zabwino kwambiri. Komabe, mavuto angapo angabuke panthawi yopanga, monga kukangana kwakukulu pakati pa zigawo za mafilimu ndi kutsekeka kwa filimu, zomwe zingachepetse kwambiri magwiridwe antchito ndikuwononga ubwino wa malonda.

Nkhaniyi ifufuza mbali zaukadaulo za filimu yopangidwa ndi PE, kuyang'ana kwambiri pachowonjezera chothandiza kwambiri chotsetsereka komanso choletsa kutsekekandi momwe zimathandizira kuthana ndi mavuto opanga kuti ziwonjezere magwiridwe antchito onse ndikuwonjezera magwiridwe antchito amafilimu.

Chidule chaukadaulo cha Kupanga Mafilimu a PE Blown ndi Zinthu Zothandiza

Chidule cha Njira Yotulutsira Mafilimu Ophulika

Njira yotulutsira filimu yophwanyidwa imayamba ndi kulowetsa ma pellets a PE resin mu extruder, komwe amasungunuka ndikusinthidwa kukhala homogenized kudzera mu kuphatikiza kwa kutentha ndi mphamvu zodula. Polima wosungunukayo amakakamizidwa kudzera mu die yozungulira, ndikupanga chubu chopitilira. Mpweya umalowetsedwa pakati pa chubu ichi, ndikuupangitsa kukhala thovu. Thovu ili limakokedwa mmwamba, nthawi yomweyo kutambasula filimuyo mbali zonse ziwiri za makina (MD) ndi mbali yopingasa (TD), njira yotchedwa biaxial orientation. Thovu likamakwera, limaziziritsidwa ndi mphete ya mpweya, zomwe zimapangitsa kuti polimayo ipangike ndi kuuma. Pomaliza, thovu lozizira limagwetsedwa ndi gulu la ma nip rollers ndikuzungulira pa roll. Magawo ofunikira omwe amakhudza njirayi ndi monga kutentha kosungunuka, die gap, blow-up ratio (BUR), frost line height (FLH), ndi cooling rate.

Zinthu Zofunika Kwambiri Zomwe Zimakhudza Kugwiritsa Ntchito Bwino Ntchito

Zinthu zingapo zimakhudza mwachindunji magwiridwe antchito a kupanga mafilimu opangidwa ndi PE:

• Kuchuluka kwa filimu: Kuchuluka kwa filimu kumapangidwa. Kuchuluka kwa filimu nthawi zambiri kumatanthauza kugwira ntchito bwino kwambiri.

• Ubwino wa Filimu: Izi zikuphatikizapo zinthu monga kufanana kwa makulidwe, mphamvu ya makina (mphamvu yogwira, kukana kung'ambika, kugwedezeka kwa dart), zinthu zowala (haze, gloss), ndi mawonekedwe a pamwamba (coefficient of friction). Ubwino woipa wa filimu umabweretsa kuchuluka kwa zinyalala ndi kuchepa kwa magwiridwe antchito.

• Nthawi Yopuma: Kuyima kosakonzekera chifukwa cha mavuto monga kusweka kwa filimu, kuuma kwa zinthu, kapena kulephera kwa zida. Kuchepetsa nthawi yopuma ndikofunikira kwambiri kuti zinthu ziyende bwino.

• Kugwiritsa Ntchito Mphamvu: Mphamvu zomwe zimafunika kuti polima asungunuke, agwiritse ntchito chotulutsira, ndi makina oziziritsira mphamvu. Kuchepetsa kugwiritsa ntchito mphamvu kumathandizira kuti zinthu zizigwira bwino ntchito komanso kumachepetsa ndalama zogwirira ntchito.

• Kugwiritsa Ntchito Zinthu Zopangira: Kugwiritsa ntchito bwino utomoni wa PE ndi zowonjezera, kuchepetsa zinyalala.

Mavuto Omwe Amakumana Ndi Mafilimu Omwe Amafalikira Kwambiri

Ngakhale kuti ukadaulo wapita patsogolo, kupanga mafilimu opangidwa ndi PE kumakumana ndi mavuto ambiri omwe angalepheretse kugwira ntchito bwino:

• Kutsekereza Filimu: Kumamatira kosafunikira pakati pa zigawo za filimu, kaya mu mpukutu kapena panthawi yokonza zinthu pambuyo pake. Izi zingayambitse mavuto pakumasuka, kuchuluka kwa zinyalala, komanso kuchedwa kupanga.

• Kukangana Kwambiri kwa Kukangana (COF): Kukangana kwakukulu pamwamba pa filimu kungayambitse mavuto panthawi yozungulira, kumasula, ndi kusintha zinthu, zomwe zimapangitsa kuti zikhale zolimba, zong'ambika, komanso kuchepetsa liwiro lokonza.

• Kumanga kwa Die: Kusonkhanitsa kwa polima kapena zowonjezera zomwe zawonongeka kuzungulira potulukira kwa die, zomwe zimapangitsa kuti pakhale mizere, ma gels, ndi zolakwika za filimu.

• Kusweka kwa chitsulo: Kusakhazikika kwa chitsulo pamwamba pa filimu chifukwa cha kupsinjika kwakukulu kwa chitsulocho, zomwe zimapangitsa kuti chiwoneke cholimba kapena chozungulira.

• Ma Gel ndi Ma Fisheyes: Tinthu ta polima tosabalalika kapena zinthu zodetsa zomwe zimaoneka ngati zolakwika zazing'ono, zowonekera bwino kapena zosawonekera bwino mu filimuyi.

Mavuto amenewa nthawi zambiri amafunika kuchepetsa ntchito yopanga zinthu, kuwonjezera zinyalala za zinthu, komanso kufunikira njira zambiri zogwirira ntchito, zomwe zimachepetsa kugwira ntchito bwino. Kugwiritsa ntchito bwino zinthu zowonjezera, makamaka zinthu zotchinga ndi zoletsa kutsekeka, kumathandiza kwambiri pochepetsa mavutowa ndikukonza bwino njira zopangira.

Njira Zogonjetsera Mavuto Pakupanga Mafilimu Apulasitiki

Kuyambitsa SILIMER Series Non-precipitating Super Slip & Anti-Blocking Additives: Yankho Limodzi la Mavuto Awiri

Pofuna kuthana ndi mavutowa, SILIKE yapanga SILIMER 5064 MB2 masterbatch, yomwe ndi njira yothandiza kwambiri yothanirana ndi mavutowa.chithandizo chogwira ntchito zosiyanasiyana chotsika mtengozomwe zimaphatikiza ntchito zotsetsereka ndi zoletsa kutsekeka mu njira imodzi. Popereka zinthu zonse ziwiri mu chinthu chimodzi, zimachotsa kufunika koyang'anira ndikupereka mankhwala owonjezera angapo.

Chowonjezera cha SILIKE Slip & Antiblock Chowonjezera Chimawonjezera Kuchita Bwino Kwanu Pakupanga Mafilimu Apulasitiki

Ubwino Waukulu wa Chowonjezera Chosasuntha/Choletsa Kutsekeka SILIMER 5064MB2 cha filimu ya PE yophulika

1. Kuwongolera ndi Kusintha Mafilimu Kwabwino

Mosiyana ndi mankhwala ochiritsira ochiritsira,SILIMER 5064 MB2 ndi masterbatc yosagwedera ndi mvulah yokhala ndi zowonjezera zoletsa kutsekeka. Imathandizira kusamalira filimu posindikiza, kuyika laminating, ndi kupanga matumba popanda kusuntha pamwamba kapena kusokoneza mtundu wa kusindikiza, kutseka kutentha, kusungunuka kwa zitsulo, kuwonekera bwino kwa kuwala, kapena magwiridwe antchito otchinga.

2. Kuwonjezeka kwa Kuchita Bwino ndi Kuthamanga kwa Ntchito

Amachepetsa coefficient of friction (COF), zomwe zimathandiza kuti mzere ukhale wothamanga kwambiri, kumasuka bwino, komanso kutulutsa ndi kusintha bwino. Kuchepetsa friction kumachepetsa kupsinjika kwa makina, kumawonjezera nthawi yogwira ntchito ya zida, kuchepetsa zosowa zosamalira, ndikuwonjezera mphamvu yogwira ntchito popanda nthawi yochepa yogwira ntchito komanso kuwononga ndalama zambiri.

3. Kupewa Kutsekereza

Zimaletsa zigawo za filimu kuti zisamamatire pamodzi, kuonetsetsa kuti zimasuka bwino komanso zikugwira ntchito bwino. Zimachepetsa kumamatira pakati pa zigawo, kuchepetsa kutsekeka, kung'ambika, kuchuluka kwa zinyalala, ndi kutaya zinthu.
4. Ubwino Wabwino wa Zinthu ndi Kukongola Kwake

Chowonjezera cha Silicone Slip SILIMER 5064 MB2 chimachotsa mpweya woipa komanso kuipitsidwa pamwamba, kupereka mafilimu osalala komanso ofanana komanso kusunga magwiridwe antchito nthawi zonse komanso umphumphu wa chinthucho.

Opanga mafilimu a PE, kodi mukuvutika ndi kukangana kwakukulu, kuletsa mafilimu, komanso nthawi yotsika mtengo yogwirira ntchito yanu yopanga? Konzani bwino ntchito zanu, chepetsani zotsalira, ndikuwonjezera magwiridwe antchito —SILIMER 5064 MB2ndiye yankho la zonse. Lumikizanani ndi SILIKE lero kuti mupemphe chitsanzo choyesera ndikudziwonera nokha kusiyana.

SILIKE imapereka njira zosiyanasiyana zothetsera mavuto. Kaya mukufuna zowonjezera pa mafilimu apulasitiki, zotchingira za mafilimu a polyethylene, kapena zotchingira zotentha zosasuntha, tili ndi zinthu zoyenera zosowa zanu.zowonjezera zotchinga zosasuntha komanso zoletsa blockZapangidwa mwapadera kuti ziwongolere magwiridwe antchito ndikukonza bwino njira yanu yopangira.
