Thermoplastic polyurethane (TPU) haingove nerubber zvimiro zvecross-linked polyurethane, senge simba rakanyanya, high wear resistance, asi ine thermoplastic properties ye linear polymer materials, kuitira kuti application yayo iwedzere kumunda wepurasitiki.Kunyanya mumakumi emakore achangopfuura, TPU yave imwe yeanokurumidza kugadzira polymer zvinhu.
TPU ine yakanakisa tension, kusimba, kusimba, uye kuchembera kuramba hunhu, zvichiita kuti ive yakakura uye ine hushamwari zvinhu.Iine simba rakakwirira, kusimba kwakanaka, kupfeka kusagadzikana, kutonhora kwekudzivirira, mafuta ekudzivirira, kudzivirira mvura, kuchembera, uye kusagadzikana kwemamiriro ekunze, izvo zvisingaenzaniswi nezvimwe zvinhu zvepurasitiki.Panguva imwecheteyo, ine yakakwirira kusapinda kwemvura uye kunyorova kwemvura, kuramba kwemhepo, kutonhora kwekudzivirira, antibacterial properties, mold resistance, uye mabasa akawanda akanaka, akadai sekuchengetedza kudziya, UV kuramba, uye kusunungurwa kwesimba.
TPU ine huwandu hwakawanda hwekushanda tembiricha.Zvigadzirwa zvakawanda zvinogona kushandiswa kwenguva yakareba mumhando ye -40-80 ℃, uye tembiricha yenguva pfupi yekushandisa inogona kusvika 120 ℃.Iwo akapfava zvikamu muchikamu chechimiro cheTPU macromolecules anoona yavo yakaderera-tembiricha kuita.Polyester mhando TPU ine yakaderera yakaderera-tembiricha kuita uye kuchinjika kupfuura polyether mhando TPU.Iyo yakaderera-tembiricha kuita kweTPU inotarirwa neyekutanga girazi shanduko tembiricha yechikamu chakapfava uye kunyorova kwekushisa kwechikamu chakapfava.Girazi rekushandura renji rinoenderana nezviri mukati mechikamu chakaoma uye chiyero chekuparadzaniswa kwechikamu pakati pezvinyoro uye zvakaoma zvikamu.Sezvo zvinyorwa zvezvikamu zvakaoma zvinowedzera uye chiyero chekuparadzaniswa kwechikamu chinoderera, girasi rekushandura girasi rezvikamu zvakapfava rinowedzerawo zvichienderana, izvo zvinotungamirira kukushaya kuderera kwekushisa.Kana polyether ine kusawirirana kwakashata nechikamu chakaoma ichishandiswa sechikamu chakapfava, iyo yakaderera-yekushisa kushanduka kweTPU inogona kuvandudzwa.Kana huremu hwemamorekuru hwechikamu chakapfava huchiwedzera kana TPU yakavharwa, dhigirii rekusawirirana pakati pezvikamu zvakapfava uye zvakaoma zvichawedzerawo.Pakupisa kwepamusoro, kushanda kwayo kunonyanya kuchengetedzwa nezvikamu zvakaoma zveketani, uye iyo yakakwirira kuoma kwechigadzirwa, iyo yakakwirira yekushanda kwayo.Mukuwedzera, iyo yepamusoro-tembiricha yekuita haisi kungoenderana nehuwandu hwemaketani ekuwedzera, asi zvakare inokonzerwa nemhando yeketani extender.Semuenzaniso, tembiricha yekushandisa yeTPU inowanikwa nekushandisa (hydroxyethoxy) benzene secheni extender yakakwira kupfuura yeTPU inowanikwa nekushandisa butanediol kana hexanediol sengetani extender.Iyo mhando ye diisocyanate inokanganisawo kudziya kwepamusoro-tembiricha yeTPU, uye akasiyana diisocyanates uye macheni ekuwedzera sezvikamu zvakaoma zvinoratidzira nzvimbo dzakasiyana dzekunyungudika.
Parizvino, chiyero chekushandisa cheTPU firimu chiri kuramba chichiwedzera uye nekuwedzera, uye chiri kuwedzera zvishoma nezvishoma kubva pachinyakare shangu, machira, zvipfeko kuenda kune aerospace, mauto, zvemagetsi uye mamwe minda.Panguva imwecheteyo, TPU firimu chinhu chitsva cheindasitiri chinogona kuramba chichigadziriswa.Iyo inogona kuwedzera nzvimbo yayo yekushandisa kuburikidza neyakaomeswa gadziriso yemidziyo, gadziriso fomula, kugadzirwa kwemaitiro uye dzimwe nzira, nekudaro ichipa TPU firimu imwe nzvimbo yekushandisa.Mune ramangwana, tekinoroji tekinoroji level ichavandudzwa, Iko kushandiswa kweTPU kuchaenda mberi.
Ndeapi mashandisirwo azvino eTPU zvinhu mukambani yedu?
Sezvo motokari dzichiita basa rinowedzera rinokosha muupenyu hwedu, kudiwa kwekuchengetedzwa kwemotokari pakati pevaridzi vemotokari kuri kuwedzerawo.Iyo TPU zvinhu zvekudzivirira pendi firimu ndiyo mhinduro yakakwana yekugadzirisa ichi chinodikanwa.
Imwe yehunhu hweTPU pendi yekudzivirira firimu ndeyekupokana kwayo kubvarura, iyo inogona kunyatso pikisa kukanganiswa kwezvinhu zvakapinza senge matombo nejecha mumugwagwa, uye kudzivirira muviri kubva kune zvikwambo uye mazino.Hapasisina chikonzero chekunetseka nezve kukuvara kunogona kuitika panguva yekutyaira, uye iwe unogona kutarisa zvakanyanya mumugwagwa uye ruzivo rwekutyaira paunenge uchityaira.
Mukuwedzera, TPU pendi yekudzivirira firimu ine yakanakisa yemamiriro ekunze kuramba.Ingave chiedza chezuva chakasimba, acid rain corrosion, kana zvinosvibisa, iri firimu rekudzivirira rependi rinogona kudzivirira zvakavimbika pendi yemota kuti isakuvare, ichichengeta mota nguva dzose iine chitarisiko chakajeka.
Chinotonyanya kushamisa ndechekuti yedu TPU zvinhu zvekudzivirira pendi firimu zvakare ine yekuzviporesa basa.Mushure mekukwenywa zvishoma, zvinhu zvayo zvinokwanisa kuzvigadzirisa munzvimbo inodziya, zvichibvumira muviri kupora sepakutanga uye kuwedzera hupenyu hwesevhisi yefirimu rekudzivirira repende.
Iyi TPU zvinhu zvekudzivirira pendi firimu haingopi kuchengetedzwa kwakazara, asi zvakare inoisa simbiso huru pakuchengetedzwa kwezvakatipoteredza.Iyo pendi yekudzivirira firimu yakagadzirwa nezvinhu zvakatipoteredza haizokonzeri chero mutoro pane zvakatipoteredza, izvo zvinoenderana nekutsvaga kwekufamba kwegirinhi nevanhu vemazuva ano.
Kuvhurwa kweTPU zvinhu zvekudzivirira pendi firimu kunoratidza shanduko mumunda wekuchengetedza mota, ichipa yakawedzera uye yakavimbika mhinduro dzekudzivirira kune varidzi vemotokari.Gamuchira kudzivirirwa kwegirinhi, rega mota dzedu nenyika zvifeme pamwechete.
Ndokumbirawo utarise kodhi yeQR iri pamusoro kuti ubate nesu zvakananga.
