Chithunzi cha LDPE 202TN00
high pressure polyethylene, ldpe popanga mafilimu, Low Density Polyethylene,

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 zabwino kwambiri extrusion filimu zakuthupi, makamaka oyenera kupanga lolemera ma CD filimu, anakhetsa filimu, kutentha shrinkable ma CD filimu ndi zina zotero.Application kuchuluka kwa otsika osalimba polyethylene: oyenera zokometsera, mikate, shuga, candied zipatso , mabisiketi, ufa wa mkaka, tiyi, floss ya nsomba ndi zoikamo zina.Kupaka kwa mapiritsi, ufa ndi mankhwala ena, kulongedza kwa malaya, zovala, zinthu za thonje zoluka ndi mankhwala a fiber ndi zinthu zina za ulusi.Kuchapa ufa, zotsukira, zodzoladzola ndi zinthu zina tsiku lililonse mankhwala ma CD.Chifukwa cha kusauka kwamakina amtundu umodzi wosanjikiza filimu ya PE, nthawi zambiri amagwiritsidwa ntchito ngati gawo lamkati la matumba ophatikizika, ndiko kuti, gawo lapansi losindikiza kutentha kwa filimu yamitundu yambiri.

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.
