Solvent-Based TPU zomatira kukhuthala kwabwino
pa TPU
TPU (thermoplastic polyurethanes) imatsekereza kusiyana pakati pa mphira ndi mapulasitiki. Kusiyanasiyana kwake kumapangitsa kuti TPU igwiritsidwe ntchito ngati rabala yolimba komanso yofewa ya engineering thermoplastic.TPU yakhala ikugwiritsidwa ntchito kwambiri komanso kutchuka muzinthu masauzande ambiri, chifukwa cha kulimba, kufewa komanso kusiyanasiyana pakati pa zabwino zina. Komanso, iwo n'zosavuta pokonza.
Monga zida zamakono zamakono komanso zachilengedwe, TPU ili ndi zinthu zambiri zabwino kwambiri monga kuuma kwakukulu, mphamvu zamakina, kukana kuzizira kwambiri, kukonza bwino, kuwonongeka kwa chilengedwe, kukana mafuta, kukana madzi ndi kukana nkhungu.
Kugwiritsa ntchito
Mapulogalamu: Zomatira zosungunulira, Mafilimu Omatira Otentha Osungunuka, Zomatira pa nsapato.

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.
Zolemba
1. Zida zowonongeka za TPU sizingagwiritsidwe ntchito pokonza zinthu.
2. Musanayambe kuumba, m'pofunika kuti muwume mokwanira, makamaka panthawi yopangira extrusion, kuwombera kuwombera, ndi filimu yowomba filimu, ndi zofunikira zolimba za chinyezi, makamaka mu nyengo yachinyontho ndi malo otentha kwambiri.
3. Pakupanga, mawonekedwe, chiŵerengero cha kuponderezana, kuya kwa groove, ndi chiŵerengero cha L / D cha screw chiyenera kuganiziridwa potengera makhalidwe a zinthuzo. Zomangira jekeseni zimagwiritsidwa ntchito popanga jekeseni, ndipo zomangira za extrusion zimagwiritsidwa ntchito potulutsa.
4. Kutengera kusungunuka kwa zinthuzo, lingalirani kapangidwe ka nkhungu, kukula kwa cholowera cha glue, kukula kwa nozzle, kapangidwe ka njira yotuluka, ndi malo a doko lotulutsa mpweya.
