TPU ipfupiso yezita rayo rechirungu (Thermoplastic polyurethanes), uye zita rayo rechiChinese ndiThermoplastic polyurethane elastomer rabha. Imhando yepolymer compound, TPU inoratidzwa nekusapfeka zvakanaka, kutwasuka kwakanaka, simba remuchina rakawanda, mashandiro akanaka ekugadzirisa, kutwasuka kupisa kwakanyanya, kutwasuka kwemvura zvakanaka. Polyurethane material, inozivikanwawo sepolyurethane, imhando itsva yezvinhu zvepolymer compound, inowanzoshandiswa muindasitiri yekugadzira, inozivikanwawo se "yechishanu purasitiki", chidimbu chezita rechirungu ndiPUR. Parizvino, zvinhu izvi zvinoshandiswa zvakanyanya, kunyanya vagadziri vetambo. Wenchang inogadzira tambo dzakawanda dzeTPU, tichaisa mashandisirwo eTPU polyurethane cable muindasitiri.
Chekutanga, tembiricha yakakwira
Kudzivirira kupisa kwakanyanya uye kuoxidation kweTPU: zvinhu zvepurasitiki zviri nyore kuoxidation munzvimbo iri pamusoro pe70℃ kwenguva yakareba, TPU ine kudzivirira kwakanaka kweoxidation; Kazhinji, kudzivirira kupisa kweTPU kunogona kusvika 120℃. Kudzivirira kupisa kwakanyanya kwePUR: tambo inochinjika zvakanyanya kanopfuura mamiriyoni makumi maviri, tambo inochinjika zvakanyanya kanopfuura mamiriyoni makumi mashanu ichashandisa PUR, nekuti ine kuchinjika kuri nani, kunodzivirira kupfeka zviri nani.
Chechipiri, kudzivirira kupisa kwakaderera
Kudzivirira kupisa kwakaderera kweTPU nePUR ndiyo sarudzo yekutanga yezvinhu zvakakurumbira mumunda wendege. Ine mukana wakakura wekushandiswa mumunda wendege, nekuti tambo yemarobhoti eTPU nePUR ine kudzikama kwakanyanya uye kugadzikana kwekutumira pakupisa kwakaderera kuri nani pane zvimwe zvinhu.
Chechitatu, kuramba mafuta uye kuvhara kupisa kuri nyore
TPU nePUR zvisina hwema hazvikuvadzi kupisa, hazvina hwema, hazvina chepfu, izvi TPU uye PUR zvinogona kufarirwa pamusika, nekuti zvinhu zvacho hazvikuvadzi mafuta, hazvikuvadzi kupfeka, hazvikuvadzi kupisa kwakanyanya, hazvina chepfu uye hazvina hwema hwakasiyana mukugadzirwa kwemaindasitiri nekugadzira zvinhu zvakakura kwazvo, saka kazhinji sarudza indasitiri yetambo iindasitiri yekugadzira michina, Inoshandiswa zvakanyanya mumaoko erobhoti nedzimwe nzvimbo dzinofambiswa, tambo iyi ine mashandiro anodiwa.
