Kodi High Density Polyethylene ndi chiyani

High kachulukidwe polyethylene (HDPE), ufa woyera kapena granular mankhwala. Zopanda poizoni, zopanda kukoma, zonyezimira za 80% mpaka 90%, zofewa za 125 mpaka 135 ° C, zimagwiritsa ntchito kutentha mpaka 100 ° C; kuuma, kulimba mphamvu ndi ductility ndi bwino kuposa otsika kachulukidwe polyethylene; kuvala kukana, magetsi Kuteteza bwino, kulimba ndi kuzizira; zabwino mankhwala bata, insoluble mu zosungunulira aliyense organic firiji, dzimbiri kukana asidi, zamchere ndi mchere osiyanasiyana; woonda filimu permeability kuti madzi nthunzi ndi mpweya, mayamwidwe madzi Low; kukana kukalamba kosauka, kukana kupsinjika kwa chilengedwe sikofanana ndi polyethylene yotsika kwambiri, makamaka matenthedwe oxidation amachepetsa magwiridwe antchito ake, chifukwa chake ma antioxidants ndi ma ultraviolet absorbers ayenera kuwonjezeredwa ku utomoni kuti apititse patsogolo kusowa uku. Filimu ya polyethylene yapamwamba imakhala ndi kutentha kochepa kosokoneza kutentha pansi pa kupsinjika maganizo, choncho tcherani khutu pamene mukuyigwiritsa ntchito.

[Dzina la Chingerezi] High Density Polyethylene
[Chidule cha Chingerezi] HDPE
[Dzina lodziwika] Ethylene yotsika kwambiri
[Kupanga monomer] Ethylene

[Makhalidwe oyambira] HDPE ndi chinthu choyera ngati sera chokhala ndi mphamvu yokoka yopepuka kuposa madzi, yokhala ndi mphamvu yokoka ya 0.941 ~ 0.960. Ndi yofewa komanso yolimba, koma yolimba pang'ono kuposa LDPE, komanso yotambasuka pang'ono, yopanda poizoni komanso yopanda kukoma.

[Makhalidwe oyaka] Imatha kuyaka ndipo imatha kupitiriza kuyaka ikasiya moto. Kumtunda kwa lawi ndi chikasu ndipo kumapeto kwa buluu. Ikayaka, idzasungunuka, padzakhala madzi akudontha, ndipo palibe utsi wakuda udzatuluka. Nthawi yomweyo, imatulutsa fungo la parafini.

[Ubwino Waikulu] Kukana kwa Acid ndi alkali, kukana kwa zosungunulira za organic, kutchinjiriza kwamagetsi kwabwino kwambiri, ndipo kumatha kukhalabe kulimba kwina pa kutentha kochepa. Kulimba kwapamtunda, kulimba kwamphamvu, kulimba ndi mphamvu zina zamakina ndizokwera kuposa LDPE, pafupi ndi PP, zolimba kuposa PP, koma kumaliza kwake sikuli bwino ngati PP.

[Zoyipa zazikulu] Zowonongeka zamakina, kusapumira bwino, kupunduka kosavuta, kukalamba kosavuta, kosavuta kukhala brittle, kufooka pang'ono kuposa PP, kupsinjika kosavuta kusweka, kulimba kwapansi, kosavuta kukanda. Zovuta kusindikiza, pamene kusindikiza, pamwamba kumaliseche mankhwala chofunika, palibe electroplating, ndipo pamwamba kuzimiririka.

[Mapulogalamu] Amagwiritsidwa ntchito popanga mafilimu opangira ma extrusion, zingwe, matumba oluka, maukonde asodzi, mapaipi amadzi; jekeseni akamaumba otsika kalasi zofunika tsiku ndi zipolopolo, sanali katundu, mabokosi pulasitiki, mabokosi zolowa; extrusion kuwomba akamaumba muli, mankhwala dzenje, mabotolo.
