TPU ipfupi pazita rayo rechiRungu (Thermoplastic polyurethanes), uye zita rayo rechiChinese rinonzi Thermoplastic polyurethane elastomer rubber.Iyo imhando yepolymer komputa, TPU zvinhu zvinoratidzwa nekupfeka kuramba, kunaka elasticity, yakakwirira mechanical simba, yakanaka kugadzirisa kuita, yakakwirira tembiricha kuramba, kunaka mvura kuramba.Polyurethane zvinhu, inozivikanwawo se polyurethane, zvakare imhando nyowani yepolymer compound material, inowanzoshandiswa muindasitiri yekugadzira, inozivikanwawo se "purasitiki yechishanu", Kupfupisa kwezita reChirungu PUR.Parizvino, zvinyorwa zvinoshandiswa zvakanyanya, kunyanya vagadziri vetambo.Wenchang inogadzira akawanda TPU tambo, isu tichasuma mashandisirwo eTPU polyurethane tambo muindasitiri.
Kutanga, kupisa kwakanyanya
High kupfeka-resistant TPU yakakwirira tembiricha kuramba uye oxidation kuramba: zvakajairika epurasitiki mbishi zvinhu zviri nyore oxidized munzvimbo iri pamusoro 70 ℃ kwenguva yakareba, TPU ine yakanaka oxidation kuramba;Kazhinji kutaura, TPU tembiricha kuramba inogona kusvika 120 ℃.PUR super kupfeka kuramba: inodarika mamirioni makumi maviri nguva yeyakanyanya kuchinjika tambo, inodarika mamirioni makumi mashanu nguva dzepamusoro flexible tambo ichashandisa PUR, nekuti ine zvirinani kukotama kuramba, kupfeka kuramba.
Chechipiri, yakaderera tembiricha kuramba
Kudzikira tembiricha kuramba kweTPU uye PUR ndiyo yekutanga sarudzo yezvinhu zvakakurumbira mumunda wendege.Iyo ine tarisiro yakakura yekushandisa mundima yeaerospace, nekuti TPU nePUR robhoti tambo ine yakanakisa kutonhora kupikisa uye kugadzikana kwekutapurirana pakudziya kwakadzika kuri nani pane zvimwe zvinhu.
Chechitatu, mafuta kuramba uye nyore kupisa chisimbiso
TPU uye PUR isina kunhuhwirira isina muchetura, isina kunhuwa, isiri-chepfu zvinhu, iyi TPU uye PUR inogona kuve yakakurumbira pamusika, nekuti iyo inodzivirira mafuta, inopfeka inodzivirira, yakanyanya kupisa tembiricha, yakanaka yakaderera tembiricha. kuramba, kusimba kwakanaka, uye hakuna chepfu uye hakuna kunhuhwirira kwakasarudzika mukugadzirwa kwemaindasitiri uye zvinangwa zvekugadzira zvakakura kwazvo, saka kazhinji sarudza indasitiri yetambo iindasitiri yekugadzira muchina, Inoshandiswa zvakanyanya mumaoko erobhoti uye mamwe majoini anofambiswa, tambo iyi ine mashandiro anodiwa. .
