Utomoni wa Thermoplastic Polyurethane (TPU) wa Mafoni Am'manja Osaonekera Kwambiri TPU Granules Wopanga Ufa wa TPU

TPU, mwachidule Thermoplastic Polyurethane, ndi thermoplastic elastomer yodabwitsa yokhala ndi zinthu zambiri zabwino komanso ntchito zosiyanasiyana.

TPU ndi block copolymer yomwe imapangidwa ndi momwe ma diisocyanates amachitira ndi ma polyol. Imapangidwa ndi magawo olimba ndi ofewa osinthasintha. Magawo olimba amapereka kulimba komanso magwiridwe antchito, pomwe magawo ofewa amapereka kusinthasintha ndi mawonekedwe a elastomeric.

Katundu

• Katundu wa Makina5: TPU ili ndi mphamvu zambiri, yokhala ndi mphamvu yokoka ya pafupifupi 30 - 65 MPa, ndipo imatha kupirira mapindikidwe akuluakulu, yokhala ndi kutalika kokulirapo mpaka 1000%. Ilinso ndi kukana kwabwino kwambiri kwa kukanda, yokhala ndi kukana kukalamba kopitilira kasanu kuposa mphira wachilengedwe, ndipo imakhala ndi kukana kwambiri kung'ambika komanso kukana kusinthasintha kwabwino, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsa ntchito yomwe imafuna mphamvu zambiri zamakanika.

• Kukana Mankhwala5: TPU imalimbana kwambiri ndi mafuta, mafuta, ndi zinthu zambiri zosungunulira. Imawonetsa kukhazikika bwino mu mafuta amafuta ndi mafuta amakina. Kuphatikiza apo, imalimbana bwino ndi mankhwala wamba, zomwe zimawonjezera moyo wautumiki wa zinthu m'malo omwe mankhwala amakhudzana nawo.

• Katundu wa Kutentha: TPU imatha kugwira ntchito bwino mkati mwa kutentha kuyambira - 40 °C mpaka 120 °C. Imasunga kusinthasintha kwabwino komanso mphamvu zamakanika kutentha kochepa ndipo siisintha kapena kusungunuka mosavuta kutentha kwambiri.

• Malo Ena4: TPU ikhoza kupangidwa kuti ikwaniritse mawonekedwe osiyanasiyana. Zipangizo zina za TPU ndizowonekera bwino, ndipo nthawi yomweyo, zimakhalabe ndi kukana kukanda. Mitundu ina ya TPU ilinso ndi mpweya wabwino, wokhala ndi mphamvu yotumizira nthunzi yomwe ingasinthidwe malinga ndi zofunikira. Kuphatikiza apo, TPU ili ndi kuyanjana kwabwino kwambiri, chifukwa si poizoni, siyambitsa ziwengo, komanso siyambitsa mkwiyo, zomwe zimapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito kuchipatala.
