PE kutentha shrinkable filimu kudziwa

Gulu la LDPE kutentha shrinkable film

Mafilimu otenthetsera kutentha kwa LDPE amagawidwa m'magulu awiri: ophatikizika komanso osalumikizana.Nthawi zambiri, opanga amagwiritsa ntchito zida zopangira ndi MFR ya 0.3-1.5g/10min popanga mafilimu osagwirizana ndi kutentha kwa LDPE.Kutsika kwa melt index, m'pamenenso shrinkage ikufanana kwambiri.Ndipo kukula kwamphamvu kwamphamvu, ndikoyeneranso kuyikapo.Opanga ena amagwiritsa ntchito ma radiation popanga kuti apititse patsogolo zinthu zosiyanasiyana zamakanema omwe amatha kutentha.
PE kutentha shrinkable filimu akhoza kukwaniritsa zofunika ma CD zinthu zambiri, ndipo ndi ambiri ntchito kutentha shrinkable filimu.MI yogwiritsidwa ntchito ndi tinthu ta LDPE ndi 0.3-1.5g / min.Kupaka filimu yolemera kapena filimu yochepetsetsa yokhala ndi zofunikira zazikulu zamphamvu, gwiritsani ntchito tinthu tating'ono ta LDPE tochepa MI, kutentha kwa LDPE ndi 130-180 ℃, kusanayambe kuzizira ndi mpweya wozizira pansi pa 25 ℃, ndiyeno mufufuze pafupi ndi mzere wa chisanu, kamodzi Longitudinal ndi yopingasa kutambasula, okwana kutambasula chiŵerengero akhoza kufika 15-35, ndiyeno filimu kuzimitsidwa pa 10-25 ° C kuti mphepo kapena kufota filimuyo.Chiwopsezo chambiri ndi 30% -50%.
Zina ndi:
1. Kanema wocheperako wa LDPE wocheperako ndi wofewa, amakhala ndi kukana kwabwino, ndipo ali ndi mphamvu yong'ambika;
2. Good otsika kutentha kukana;
3. Zosavuta kukonza ndi kupanga, zosavuta kutentha thumba losindikiza;
4. Palibe kuchepa komwe kumachitika panthawi yosungira.Kupukutira kwa galasi, zoumba, chakudya, zomangira, mankhwala, pallets, etc. Makulidwe a ma CD kuwala ndi 0.02-0.06mm, ndi makulidwe a katundu pallet lalikulu ndi lalikulu ndi 0.075-0.25mm.

Katundu wa LDPE shrink filimu:
1. Wowonda filimu makulidwe ndi 0.02-0.05mm, sing'anga mtundu ndi 0.05-0.10mm, ndi mtundu wandiweyani ndi 0.10-0.15mm;
2. Mphamvu yamakomedwe ndi 28-38MPa yamtundu woonda, 20-30MPa yamtundu wapakati, ndi 20-28MPa yamtundu wandiweyani;
3. Kutsika kwamtundu wochepa thupi ndi 55% -65%, mtundu wapakati ndi 45% -60%, mtundu wakuda ndi 30% -50%;shrinkage kutentha mafuta kusamba ndi 110-120 ℃, mpweya otentha ndi 170-180 ℃;
4. Nthawi yocheperako ndi 5-10s yamtundu woonda ndi 20-30s yamtundu wokhuthala.
Makulidwe ochepa a filimu yochepetsera pakuyika zosakwana 400kg ndi 120μm, 800kg imafunikira makulidwe a 150μm, ndipo katundu wa 1200kg amafunikira filimu yocheperako ya LDPE yokhala ndi makulidwe a 200μm.
