Zvakanakira nezvakaipa zve ETPU Materials

Posted by: PECOAT | musi waNyamavhuvhu 16, 2023

ETPU (thermoplastic polyurethane elastomer) ndeye thermoplastic elastomer zvinhu zvinoumbwa nepolyether polyols uye polyisocyanates. Hezvino zvakanakira nekuipira ETPU zvinhu:

Advantages:

1. Kuramba kwakasimba kupfeka: ETPU ine kuomarara kwepamusoro uye kusimba kupfuura zvechinyakare rabha nepurasitiki, saka ine yakasimba kupfeka kuramba uye kusimba.
2. Oiri nemvura kuramba: ETPU ine mafuta akanaka uye inodzivirira mvura, uye inogona kushandiswa kwenguva yakareba munzvimbo dzakanyorova kana dzine mafuta pasina kukuvara nyore.
3. Good processability: ETPU zvinhu zvinogona kugadziriswa kuita akasiyana maumbirwo ezvigadzirwa kuburikidza nekuumbwa kwejekiseni, extrusion, calendering uye dzimwe nzira dzekugadzirisa, dzinogona kusangana nezvinodiwa zvekushandisa kwakasiyana.
4. Yakanaka elasticity: ETPU ine elasticity yakanaka uye kusimba, iyo inogona kunyatso kudzikisa kukanganisa uye kuzununguka, uye kudzivirira zvinhu kubva mukukuvara.
5. Hushamwari kwezvakatipoteredza: ETPU zvinhu zvinogona kushandiswazve uye zvakatipoteredza.

payakaipira:

1. Mutengo wepamusoro: Kuenzaniswa nerabha yechinyakare uye zvepurasitiki zvinhu, ETPU inodhura.
2. Kusagadzikana kwekushisa kwepamusoro: ETPU ine hutsika husina kunaka hwekushisa uye haigoni kumira kushandiswa kwenguva refu pakupisa kwepamusoro.
3. Isingadzivirirwe nemwaranzi yeultraviolet: Mushure mekuratidzwa kuchiedza chezuva kwenguva yakati, ETPU richava rakaoma, brittle, uye kunyange kurasikirwa kwayo elasticity.

Mukupfupisa, ETPU zvinhu zvine mabhenefiti akawanda, kunyanya mumashandisirwo anoda kusimba kwepamusoro, kupfeka kuramba, uye elasticity. Nekudaro, pane zvakare zvimwe zvipingamupinyi zvekuziva, senge mutengo wepamusoro, kushomeka kwekushisa kwekushisa kwepamusoro, uye kusamira zvakanaka kune ultraviolet mwaranzi.
