PFAS-Free Polymer Processing Aids (PPA) ya PE Film Extrusion

Kubwezeretsa Fluoropolymer pa Kukonza Filimu Yokhazikika, Yothamanga Kwambiri

Ndi mavuto ati omwe amalepheretsa kutulutsa filimu ya PE masiku ano?

Kutulutsa filimu ya polyethylene (PE) pogwiritsa ntchito LLDPE, HDPE, ndi mLLDPE nthawi zambiri kumachepetsedwa ndi kusweka kwa kusungunuka, kupangika kwa sharkskin, ndi kutuluka kwa die kosakhazikika pansi pa mikhalidwe yothamanga kwambiri.

Zolakwika izi zimachitika chifukwa cha kusakhazikika kwa kukangana pakati pa polima ndi pamwamba pa chitsulo, makamaka pamene pali kupsinjika kwakukulu kwa shear.

Ma PPA okhala ndi fluoropolymer akhala akugwiritsidwa ntchito kale kuti akhazikitse magwiridwe antchito, koma kuwonjezeka kwa kukakamizidwa kwa malamulo a PFAS kukufulumizitsa kusintha kwa njira zina zopanda fluorine.

Chifukwa chiyani kusungunuka kwa melting kumachitika mu PE film extrusion?

Kusweka kwa kusungunuka kumachitika pamene kuyenda kwa polima kusungunuka kumasintha kuchoka pa kusweka kokhazikika kupita ku kusakhazikika kwa ndodo pambuyo popitirira kupsinjika kwakukulu kwa kusweka pamalo otulukira.

Izi zimasokoneza kupitirira kwa gawo losungunuka pamwamba pa die, zomwe zimapangitsa kuti khungu la shark likhale lofooka komanso mawonekedwe osafanana a filimu.

Chiwopsezochi chimawonjezeka ndi liwiro lalikulu la mzere, mipata yopapatiza ya die, ma resins olemera kwambiri a molekyulu, ndi ma polyethylene okhala ndi metallocene.

Chifukwa chiyani ma PPA a fluoropolymer akusinthidwa?

Ma PPA a Fluoropolymer amagwira ntchito posamukira pamwamba pa die ndikupanga mafuta ochepa omwe amachepetsa kukangana ndikukhazikitsa kuyenda kwa madzi osungunuka.

Komabe, kupirira kwawo kwa chilengedwe monga zinthu zokhudzana ndi PFAS kukuyendetsa malamulo oletsa ku EU, North America, ndi madera ena.

Zotsatira zake, opanga mafilimu akusunthira ku machitidwe osagwiritsa ntchito fluorinated processing omwe amasunga:

• Kukhazikika kwa liwiro la mzere wapamwamba

• Chifunga chochepa komanso chowala kwambiri

• Ukhondo wa nthawi yayitali

• Kutsatira malamulo

Kodi ma PPA opanda PFAS amachotsa bwanji kusungunuka kwa madzi?

Ma PPA opanda PFAS amachepetsa kusweka kwa kusungunuka mwa kusintha mphamvu za pakati pa kusungunuka kwa polima ndi kufa m'malo modalira kuchepetsa mphamvu za pamwamba pa fluorinated.

Amapanga gawo lolamulira la mafuta odzola pogwiritsa ntchito njira yolumikizirana ndi mawonekedwe achitsulo ndi matrix a polima, zomwe zimapangitsa kuti zinthu zikhazikike bwino panthawi yotulutsa.

Njira imeneyi imaletsa kusakhazikika kwa ndodo ndi kutsetsereka, imachepetsa kusinthasintha kwa kupsinjika kwa shear, komanso imapangitsa kuti pamwamba pakhale kufanana kwa mphamvu zambiri.

Ukadaulo wa PPA wopanda SILIMER PFAS wa PE Film Extrusion

Momwe ma PPA opanda SILIMER PFAS amagwirira ntchito mu PE extrusion

Ma PPA opanda PFAS a SILIKE SILIMER amapangidwira makina otulutsa polyolefin omwe amafunikira kukhazikika mwachangu komanso kupanga mafilimu opanda chilema.

Kuchita kwawo kumadalira kapangidwe ka mamolekyulu a magawo ambiri:

• Zigawo za polar

Gwirizanani ndi malo achitsulo (skuruu, mbiya, die) ndikupanga gawo lokhazikika la mafuta olumikizirana lomwe limachepetsa kusungunuka ndikuletsa kusonkhana kwa die.

• Msana wa Polysiloxane

Amapereka kukangana kochepa kwambiri komanso kukhazikika kwa kutentha kwambiri, zomwe zimapangitsa kuti kayendedwe ka kusungunuka kakhale bwino pakagwiritsidwa ntchito mphamvu.

• Unyolo wa hydrocarbon wosagwiritsa ntchito polar

Onetsetsani kuti zikugwirizana ndi ma PE/PP matrices ndipo zimalola kufalikira kofanana komanso kusamuka kolamulidwa panthawi yotulutsa.

Kapangidwe kameneka kamathandiza kupangidwa kwa gawo lodzola losinthasintha, lodzikonzanso lokha lomwe limalowa m'malo mwa njira zosinthira pamwamba zochokera ku fluoropolymer.

Kodi ma PPA opanda SILIMER PFAS amapereka maubwino otani pakuchita bwino?

Monga zowonjezera zachikhalidwe zogwiritsa ntchito Fluoropolymer, zikagwiritsidwa ntchito mu LLDPE, HDPE, kapena mLLDPE extrusion systems, ma SILIKE SILIMER PFAS-free PPAS monga Fluoropolymer PPA Alternative, amapereka:

♦ Kuchotsa kusweka kwa ming'alu ndi zolakwika za khungu la shaki

♦ Kuchepa kwa ma die buildings komanso kukhazikika kwa magwiridwe antchito

♦ Kuchepetsa kuthamanga kwa mpweya wotuluka m'thupi komanso kugwiritsa ntchito bwino mphamvu

♦ Kugwira ntchito bwino kwa kuwala kuphatikizapo kuwala kwa chifunga ndi kuwala kowala

♦ Kutulutsa kokhazikika mu njira zowulutsa, zowonetsera, komanso zamitundu yambiri

Kodi ma PPA opanda PFAS amagwirizana bwanji ndi machitidwe omwe alipo a extrusion?

Ma PPA opanda SILIMER PFASZapangidwa ngati njira zothetsera mavuto zomwe zilipo kale pamizere yopangira polyolefin.

Zinthu mongaPPA SILIMER 9100 yopanda fluorinendiPPAS-Free PPA Masterbatch SILIMER 9301Zitha kulowetsedwa mwachindunji mu makina ophatikiza kapena a masterbatch popanda kusintha zida.

Zimagwirizana ndi:

Kodi ma PPA opanda PFAS amathandizira bwanji kutsatira malamulo?

Ma PPA opanda PFAS (monga, zinthu za mndandanda wa SILIMER ndiZothandizira polima zopanda PFAS, zomwe zinafufuzidwa ndi kupangidwa ndi Chengdu Silike. IziZothandizira kukonza zinthu zopanda fluoropolymerKuchotsa zinthu zosungunuka zomwe zimakhalabe ndi fluorine ndikuthandizira kusintha kwa malamulo apadziko lonse lapansi kupita ku machitidwe otetezeka opangira ma polima.

Iwo amagwirizana ndi:

→ Malamulo a EU Okhudza Kuyika ndi Kuyika Zinyalala (PPWR)

→ Malamulo atsopano a PFAS ku North America

→ Chuma chozungulira ndi njira zokhazikika zosungiramo zinthu

Ndi mapulogalamu ati omwe ali oyenera kugwiritsa ntchito ma PPA opanda SILIKE SILIMER PFAS?

Ma PPA opanda SILIKE SILIMER PFAS ndi oyenera mitundu yosiyanasiyana ya makina opangira polyolefin, kuphatikizapo:

♦ Kutulutsa filimu yopsereza

♦ Kupanga mafilimu a ochita sewero

♦ Makanema opaka okhala ndi zigawo zambiri

♦ Kukonzanso polyolefin

♦ Makina a PE a metallocene othamanga kwambiri

♦ Ulusi, monofilament, chingwe, ndi chitoliro chotulutsira

♦ Masterbatch ndi machitidwe ophatikiza

Chidule chaukadaulo

Ma PPA opanda PFAS, monga mndandanda wa SILIKE SILIMER, amaphatikizapo zowonjezera zopanda fluorine,ma masterbatches opanda fluorine,Ma PPA opanda fluorine,Zowonjezera zopanda PTFE, ndi zothandizira kukonza ma extrusion zopanda PFAS. Mafuta odzola a polima awa adapangidwa kuti alowe m'malo mwa kusintha kwa pamwamba pa fluoropolymer ndi njira yolumikizirana pakati pa ma molecular interfacial.
