# Isivimbeli selangabii-thermoplastic polyurethane(TPU) ye-UL94 V-0 grade iyi-elastomer esebenza kahle kakhulu eyenzelwe ngokukhethekile ukuvikela izintambo kanye nokubopha. Ihlanganisa ukuphepha komlilo okumangalisayo, ukuqina kwemishini, kanye nokumelana nemvelo, okwenza kube kuhle kakhulu ezintanjeni zamandla, zokuxhumana, zezimoto, kanye nezezimboni.
### Ukusebenza Okungalawuli Ilangabi Eliyisihluthulelo – **I-UL94 V-0Isilinganiso**: Ifinyelela esigabeni se-V-0 ngobukhulu obungu-1.5mm, iqinisekisa **ukuzicisha ngaphakathi kwemizuzwana emi-5** futhi akukho ukuconsa kwezinhlayiya ezivuthayo ezivuthisa izinto ezivuthayo. – **Ukuhambisana neMigomo Yekhebula**: Kudlula **IEC 60332-1-2** (ukusha okukodwa okuqondile) kanye ne-**UL 1581 VW-1** (ukuhlolwa komlilo wentambo eqondile), okuhlangabezana nezidingo zokuphepha komlilo emhlabeni wonke wezintambo. – **Umusi Ongena-Halogen kanye Nomusi Ophansi**: Ukwakheka okunobungani nemvelo (akukho ma-halogen) kukhipha **intuthu ephansi kanye nobuthi obuphansi** ngesikhathi sokusha, okubaluleke kakhulu ezindaweni zomphakathi, izikhungo zedatha, kanye nezinhlelo zokusebenza ze-EV.
### Izinzuzo Zezinto Eziyinhloko 1. **Izakhiwo Eziphezulu Zemishini** – Amandla aphezulu okudonseka (≥15–30 MPa) kanye nokumelana nokudabuka (≥40 N), ukumelana nokuklwebheka, ukushayisana, kanye nokucindezeleka kwemishini ngesikhathi sokufakwa nokusetshenziswa. – Ukuguquguquka okuhle kakhulu (ukunwebeka ngesikhathi sokuphumula: 450%–550%) ebangeni lokushisa elibanzi (-50°C kuya ku-125°C), kugcina ukunwebeka emakhazeni noma ekushiseni okukhulu. 2. **Ukumelana Okuhle Kwemvelo** – **I-Hydrolysis kanye Nokumelana Namakhemikhali**: Imelana namahora ayi-1,000–2,000 e-hydrolysis (85°C/85% RH) futhi imelana namafutha, ama-acid, ama-alkali, kanye nemisebe ye-UV, yandisa impilo yesevisi yekhebula. – **Ukumelana Nesikhunta Nokukhunta**: Ihambisana nezindinganiso zempi (GJB 150.10), ifanele izindawo ezinomswakama nezinolaka. 3. **Ukucubungula Nokusetshenziswa Okuguquguqukayo** – Kufanelekela **ukukhipha kanye nokubumba umjovo**, okuvumela ukukhiqizwa okuphumelelayo kwamajakethi ekhebula kanye nezendlalelo zokufaka umswakama. – Ubulukhuni obungenziwa ngokwezifiso (Shore A 70–95) nemibala, okusekela imiklamo ehlukahlukene yekhebula kanye nezidingo zokumaka.
### Izicelo Ezijwayelekile – **Amakhebula Okushaja E-EV**: Ukumelana nogesi ophezulu, ukuphepha komlilo, kanye nokuqina kwezinhlelo zokushaja izimoto zikagesi. – **Amakhebula Okuxhumana Nedatha**: Anentuthu ephansi, angenawo i-halogen, kanye nokushisa okuphezulu kukagesi kwezikhungo zedatha kanye namanethiwekhi ezokuxhumana. – **Amakhebula Ezimoto**: Amelana namafutha, ukushisa, kanye nokudlidliza kokuxhuma kwenjini kanye nokuxhumana ngaphakathi kwemoto. – **Amakhebula Ezimboni Nawasolwandle**: Amelana namakhemikhali aqinile, i-UV, kanye namazinga okushisa aphezulu emishinini yezimboni kanye nemishini yasolwandle.
### Ukuthobela Imithetho kanye Nezitifiketi – **UL94 V-0** (1.5mm), **RoHS**, **REACH**, **IEC 60332**, **UL 1581**. – Ayinayo i-halogen, intuthu ephansi, kanye nobuthi obuphansi, okuhambisana nemithethonqubo yezemvelo kanye nokuphepha yomhlaba wonke. Le TPU evimbela ilangabi ye-V-0 ilinganisa **ukuphepha komlilo, ukuqina, kanye nokusimama**, isebenza njengesixazululo esithembekile sezintambo ezisebenza kahle kakhulu ezinhlelweni ezibalulekile zokuphepha.
