Otsika osalimba Polyethylene 2102TN00
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
LDPE ili ndi ntchito yabwino yopangira filimu ndipo imapanga zinthu zabwino zowoneka bwino, makina amakina ndi kusindikiza kutentha, kukana kuzizira, kutentha kochepa komanso kutentha kwakukulu.Kanema wokhuthala amatha kupirira njira yotsekereza yoviikidwa m'madzi otentha a 90 ℃.Amagwiritsidwa ntchito kwambiri m'makampani opanga ma CD.
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.

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.
