Polyether mtundu TPU-M mndandanda/ Polycarbonate granules/Pulasitiki zopangira/Tpu pulasitiki zopangira mtengo
pa TPU
Thermoplastic polyurethane elastomer (TPU) ndi mtundu wa elastomer yomwe imatha kupangidwa ndi pulasitiki potenthedwa ndikusungunuka ndi zosungunulira. Ili ndi zinthu zabwino kwambiri zophatikizira monga mphamvu yayikulu, kulimba kwambiri, kukana kuvala komanso kukana mafuta. Ili ndi ntchito yabwino yopangira ndipo imagwiritsidwa ntchito kwambiri poteteza dziko, zamankhwala, Chakudya ndi mafakitale ena. Thermoplastic Polyurethane ili ndi mitundu iwiri: polyester mtundu ndi polyether mtundu, woyera mwachisawawa ozungulira kapena columnar particles, ndi kachulukidwe ndi 1.10 ~ 1.25g/cm3. Kachulukidwe wachibale wa mtundu wa polyether ndi wocheperako kuposa mtundu wa polyester. Kutentha kwa galasi la polyether ndi 100.6 ~ 106.1 ℃, ndi kutentha kwa galasi la polyester ndi 108.9 ~ 122.8 ℃. Kutentha kwa brittleness kwa mtundu wa polyether ndi mtundu wa poliyesitala ndikotsika kuposa -62 ℃, ndipo kukana kwa kutentha kwa mtundu wa polyether ndikobwino kuposa mtundu wa poliyesitala. Zodziwika bwino za polyurethane thermoplastic elastomers ndizovala bwino kwambiri, kukana kwa ozoni, kulimba kwambiri, kulimba kwambiri, kukhazikika bwino, kutsika kwa kutentha, kukana bwino kwamafuta, kukana kwamankhwala ndi kukana chilengedwe. Kukhazikika kwa hydrolytic kwa mtundu wa ester ndikokwera kwambiri kuposa mtundu wa polyester.
Kugwiritsa ntchito
Animal Ear Tag, Zida Zamasewera, Hose yamoto, Machubu, Flexitank, Waya&Chingwe, zokutira Nsalu, Filimu&Sheet, ndi zina zambiri.

Miyezo yomwe ili pamwambayi ikuwonetsedwa ngati milingo yeniyeni ndipo sayenera kugwiritsidwa ntchito ngati mafotokozedwe.
Phukusi
25KG / thumba, 1000KG / mphasa kapena 1500KG / mphasa, kukonzedwa mphasa pulasitiki
Kugwira ndi Kusunga
1. Pewani kupuma utsi ndi nthunzi zomwe zimagwiritsidwa ntchito chifukwa cha kutentha
2. Zida zogwirira ntchito zamakina zimatha kuyambitsa fumbi. Pewani kupuma fumbi.
3. Gwiritsani ntchito njira zoyenera zoyankhira pogwira mankhwalawa kuti musawononge magetsi
4. Ma pellets pansi amatha kuterera ndikupangitsa kugwa
Malangizo posungira: Kuti katundu asungidwe bwino, sungani pamalo ozizira komanso owuma. Sungani mu chidebe chotsekedwa mwamphamvu.
