LDPE Granules Omwe Amagwiritsidwa Ntchito Mu Shed Film,
LDPE yopanga mafilimu okhetsedwa, LDPE yogwiritsidwa ntchito pokhetsa filimu,
Polyethylene yotsika kwambiri (LDPE) ndi utomoni wopangidwa pogwiritsa ntchito njira yoponderezedwa kwambiri kudzera mu polymerization yaulere ya ethylene ndipo imatchedwanso "polyethylene yapamwamba".Low kuthamanga polyethylene fungo, zoipa, sanali poizoni woyera particles kapena ufa.Malo osungunuka ndi 131 ℃.Kachulukidwe 0.910-0.925 g/cm³.Malo ochepetsera 120-125 ℃.Embrittlement kutentha -70 ℃.Zolemba malire ntchito kutentha 100 ℃.Ndi kukana kwambiri kutentha, kukana kuzizira, kukana kuvala ndi katundu wa dielectric, kukhazikika kwamankhwala.Pafupifupi insoluble aliyense organic zosungunulira firiji.Ingathe kupirira dzimbiri zosiyanasiyana asidi ndi zamchere ndi zosiyanasiyana mchere.Polyethylene yotsika kwambiri imagwiritsidwa ntchito kwambiri m'mafakitale opanga mankhwala ndi mankhwala kuti apange zinthu zopanda kanthu, monga migolo, mabotolo ndi matanki osungira.Makampani opanga zakudya amachigwiritsa ntchito kupanga zotengera.Makampani opanga makina amagwiritsidwa ntchito popanga zophimba, zogwirira, mawilo am'manja ndi zida zina zamakina, ndipo makampani opanga mapepala amagwiritsidwa ntchito kupanga mapepala opangira.

Mbali

Kugwiritsa ntchito

LDPE(2102TN000) ndi yabwino kwambiri extrusion filimu chuma, makamaka oyenera kupanga katundu ma CD filimu, anakhetsa filimu, kutentha shrinkable ma CD filimu ndi zina zotero.

Parameters

Phukusi, Kusungirako ndi Mayendedwe

Utotowo umayikidwa m'matumba opangidwa ndi filimu ya polypropylene.Kulemera konse ndi 25Kg / thumba.Utoto uyenera kusungidwa m'nyumba yosungiramo madzi, youma komanso kutali ndi moto ndi dzuwa.Asamawunjikane panja.Poyendetsa, mankhwalawa sayenera kukumana ndi dzuwa lamphamvu kapena mvula ndipo asatengedwe pamodzi ndi mchenga, nthaka, zitsulo, malasha kapena galasi.Kuyendera limodzi ndi zinthu zapoizoni, zowononga komanso zoyaka moto ndizoletsedwa.

1. LDPE imagwiritsidwa ntchito makamaka popanga mafilimu.Amagwiritsidwa ntchito kwambiri popanga
- filimu yaulimi (mulching filimu ndi filimu yokhetsedwa),
- filimu yolongedza (yogwiritsidwa ntchito ponyamula maswiti, masamba ndi zakudya zozizira),
- filimu yowomberedwa yoyikapo zamadzimadzi (zogwiritsidwa ntchito pakuyika mkaka, msuzi wa soya, madzi, nyemba zamkaka ndi mkaka wa soya),
- matumba onyamula katundu wolemetsa,
- filimu yochepetsera thupi,
- elastic filimu,
- filimu yowonongeka,
- filimu yogwiritsira ntchito,
- filimu yodzaza ndi mafakitale ndi matumba azakudya.
