Filimu yapulasitiki ndi mtundu wazinthu zapulasitiki zomwe zimagwiritsidwa ntchito kwambiri pakuyika, ulimi, zomangamanga, ndi zina. Ndi yopepuka, yosinthasintha, yowonekera, yosamva madzi, acid-ndi alkali yosamva, ndipo imakhala ndi umboni wabwino wa chinyezi, fumbi, kusungirako mwatsopano, kuteteza kutentha, ndi ntchito zina. Pakali pano, mafilimu ambiri apulasitiki pamsika ndi makamaka polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), ndi zina zotero.

Filimu ya polythene ndi imodzi mwa mafilimu apulasitiki omwe amagwiritsidwa ntchito kwambiri pamsika masiku ano. Amadziwika ndi kusinthasintha kwabwino, kuwonekera kwambiri, komanso kukana kwa dzimbiri.

Malinga ndi makulidwe osiyanasiyana a polyethylene, filimu ya polyethylene imagawidwanso kukhala filimu ya polyethylene yotalika kwambiri (HDPE) ndi filimu ya polyethylene yotsika kwambiri (LDPE). Kanema wa HDPE ali ndi mphamvu zambiri komanso kuuma, ndipo ndi oyenera kuyika zida ndi filimu yopangira mulching yaulimi ndi magawo ena; Kanema wa LDPE ndi wosinthika komanso woyenera kulongedza zakudya ndi matumba a zinyalala ndi magawo ena.

Njira yopangira filimu ya polyethylene makamaka imaphatikizapo njira ya extrusion ndi njira yowombera filimu. Malinga ndi njira zosiyanasiyana zopangira mafilimu, amatha kugawidwa m'mitundu ingapo, monga filimu yowombedwa (IPE), filimu yotayidwa (CPE), ndi filimu yotsika thovu.

Mphamvu zolimba za filimu ya PE ndi kutseguka zili bwino kuposa filimu ya CPE, pogwiritsa ntchito kusindikiza kutsogolo, kungagwiritsidwe ntchito pamatumba a chakudya, matumba a zovala, ndi zina zotero; Kufanana kwa filimu ya CPE, gloss pamwamba, kuwonekera, ndi kusindikiza kutentha kuposa PE kuli bwino, kumatha kusindikizidwa kutsogolo ndi kumbuyo, koma mtengo wake ndi wokwera. Filimu ya CPE imagwiritsidwa ntchito makamaka ngati thumba lamagulu amkati, komanso zodzoladzola, sauces, ndi makeke a ma CD; filimu yotsika kwambiri ya thovu ndi yokongoletsera, yokhuthala, yosavuta kutambasula ndi kupunduka, pogwiritsa ntchito kusindikiza kutsogolo, zomwe zimagwiritsidwa ntchito pa zojambula za Chaka Chatsopano, zizindikiro ndi zikwama zam'manja. Kanema wa thovu lotsika ndi wabwino kukongoletsa, kapangidwe kake, sikophweka kutambasula ndi kupunduka, ndipo amasindikizidwa kutsogolo, ndikugwiritsidwa ntchito muzojambula za Chaka Chatsopano, zizindikiro, ndi zikwama zam'manja.

Kanema wa PE m'malo opangira ma CD ndi omwe amagwiritsidwa ntchito kwambiri ndipo amatha kugwiritsidwa ntchito popanga chakudya, kuyika zinthu zamagetsi zamagetsi, kuyika zofunikira tsiku ndi tsiku, kunyamula zovala, ndi zina zotero. Iwo ali ndi mfundo yofanana, ndiye kuti, filimu ya pulasitiki ndi yosindikizira mitundu, monga kusungirako chakudya komanso kwamagulu ambiri osanjikiza ndi ntchito zina.

Komabe, filimu ya PE imakonda kukhala ndi mawanga a kristalo, ndipo kutsekemera kwa ufa woyera nthawi zonse kwakhala vuto la clichéd, lomwe ndilofala kwambiri pakupanga mafilimu, komanso mutu waukulu kwambiri. Ambiri opanga mafilimu akhudzidwa ndi filimu yowonongeka yomwe imakhudza kusindikiza kotsatira, komanso ubwino wa mankhwala omaliza.

Ngakhale kuti mavuto a crystal point ndi ofala, si ophweka kuthetsa. Izi zili choncho makamaka chifukwa pali zinthu zambiri zomwe zingayambitse mavuto a crystal point. Ngati chifukwa cha kristalo pitting sichidziwika bwino, n'zovuta kuchitapo kanthu kuti akonze kapena kuthetsa. Choncho, choyamba tiyenera kumvetsa zomwe zimayambitsa kristalo pitting, amene amayamba ndi zinthu zisanu zotsatirazi:

• Zoyipa zakunja
• Popanda plasticization
• Crosslinking pambuyo ukalamba / makutidwe ndi okosijeni
• Carbonisation wa zinthu panthawi yokonza, zomwe zimapangitsa "carbon deposits in the mouth mold".
• Mvula yowonjezera, etc.

Ma slip agents a mafilimu a PE nthawi zambiri amakhala oleic acid amide kapena erucic acid amide, ndipo ntchito ya toning imafuna kuti iwonongeke pamwamba pa filimuyo, apo ayi sipadzakhala kutsetsereka. Wosalala wothandizila chifukwa anawonjezera, osati kumtengowo pa molekyulu Pe, filimu processing, ndi ndimeyi ya nthawi ndi kusintha kutentha, wothandizila yosalala adzakhala kuchokera filimu pamwamba wosanjikiza wa mkati nembanemba kwa kusamuka kunja ukutuluka. Kuyang'anitsitsa mosamala kudzapezeka kuti ndi gawo lochepa kwambiri la ufa kapena zinthu zonga sera, nthawi yayitali, kusuntha kwambiri. Pamene yosalala wothandizila mpweya ndi kwambiri, osati kumakhudza ntchito ya makina ma CD okha, komanso kumakhudza kuyenerera kusindikiza, mphamvu gulu, ndi kuipitsa katundu mmatumba.

Kusokoneza miyambo, kufufuza, ndi kupanga zatsopano, ndiMndandanda wa SILIKE SILIMER Wowonjezera Wopanda Kusamuka WosamukaPakuti Flexible Packaging amathetsa bwino vuto la precipitates woyera, Nthawi yomweyo, iziNon-precipitation slip agentitha kuthandizanso opanga mafilimu a PE pothana ndi zovuta za crystallization point panthawi yopanga.

Gulu lodzipatulira la SILIKE la R&D lathana bwino ndi zovuta izi ndi chitukuko chambirinon-Blooming Super-slip & anti-blocking Masterbatch Additives - gawo la mndandanda wa SILIMER, yomwe imathetsa bwino zofooka za ogwiritsira ntchito slip agent, Osasuntha m'magulu a mafilimu, kuonetsetsa kuti ntchito yokhazikika komanso yokhalitsa, yomwe imabweretsa zatsopano ku makampani a Plastic Film Flexible Packaging Industry. Kupambana kumeneku kumapereka maubwino monga kukopa pang'ono kusindikiza, kusindikiza kutentha, kutumiza, kapena chifunga, pamodzi ndi CoF yochepetsedwa, kutsekereza kwabwino, komanso kusalala kwa pamwamba, kuthetsa mvula yoyera ya ufa.

Mndandanda wa SILIMER Wopanda mpweya wabwino kwambiri & anti-blocking Masterbatch Additives mndandandaali ndi mapulogalamu ambiri ndipo angagwiritsidwe ntchito popanga mafilimu a BOPP / CPP / PE / TPU / EVA, ndi zina zotero.

Ubwino waMndandanda wa SILIKE SILIMER Wopanda kutentha kwambiri komanso anti-blocking Masterbatch Additives:

1.Deta yoyesa ikuwonetsa kuti zochepa zaSILIKE SILIMER 5064MB1,ndiSILIKE SILIMER 5065HBimatha kuchepetsa kugundana kwamphamvu komanso kukhala ndi kuterera kwanthawi yayitali komanso kokhazikika mosasamala za nyengo ndi kutentha;

2.Kuwonjezera kwaSILIKE SILIMER 5064MB1,ndiSILIKE SILIMER 5065HBpanthawi yokonza mafilimu apulasitiki sizimakhudza kuwonekera kwa filimuyo ndipo sizikhudza ndondomeko yosindikiza yotsatila;

3.KuwonjezeraSILIKE SILIMER 5064MB1,ndiSILIKE SILIMER 5065HBpang'ono pang'onopang'ono amathetsa vuto loti ma amide slip agents amatha kutsika mosavuta kapena ufa, amapangitsa kuti malondawo akhale abwino, ndikupulumutsa mtengo wokwanira.

Kodi mukufuna kusintha ma amide slip agents omwe ali m'manja mwanu? Kodi mukufuna m'malo mwa amide slip agent wanu wa Plastic Film, kapena mukufuna kugwiritsa ntchito njira yokhazikika komanso yodalirika yotetezera zachilengedwe pa Filimu ya Plastic, SILIKE amakulandirani kuti mutilankhule nthawi iliyonse, ndipo tikuyembekezera kupanga zambiri zotheka pamodzi ndi inu!
