Kuoma kweTPU (thermoplastic polyurethane elastomer)ndechimwe chezvinhu zvayo zvakakosha zvemuviri, izvo zvinotarisa kugona kwechinyorwa kuramba deformation, makorokoza, uye mavanga.Hurema hunowanzoyerwa pachishandiswa shore hardness tester, iyo yakakamurwa kuita mhando mbiri dzakasiyana: Shore A neShore D, inoshandiswa kuyera.TPU zvinhupamwe nekuoma kwakasiyana siyana.
Zvinoenderana nemhedzisiro yekutsvaga, hurema hweTPU hunogona kubva kuShore 60A kuenda kuShore 80D, iyo inobvumira TPU kupfuudza kuomarara kwerabha nepurasitiki uye kuchengetedza yakakwira elasticity mukati mekuoma kwese kwese.Kugadziriswa kwekuoma kunogona kuwanikwa nekushandura chikamu chezvikamu zvinyoro uye zvakaoma muTPU molecular chain.Shanduko yekuomarara inogona kukanganisa zvimwe zvinhu zveTPU, zvakaita sekuwedzera kuomarara kweTPU zvichitungamira mukuwedzera kwekusimba modulus uye kubvarura simba, kuwedzera kwekuoma uye kudzvinyirira kushushikana, kudzikira mukurebesa, kuwedzera density uye ine simba chizvarwa chekupisa. , uye kuwedzera kwekudzivirira kwezvakatipoteredza.
Mukushandisa zvinoshanda, iyokuoma kusarudzwa kweTPUzvinozotemwa zvichibva pane chaiyo application zvinodiwa.Semuenzaniso, TPU yakapfava (yakayerwa neShore A hardness tester) inokodzera zvigadzirwa zvinoda kubata kwakapfava uye kureba kwakakwirira, nepo TPU yakaoma (yakayerwa neShore D kuomarara tester) inokodzera zvigadzirwa zvinoda yakakwirira-yekutakura mutoro uye yakanaka. kupfeka kuramba.
Uye zvakare, vagadziri vakasiyana vanogona kuve neyakaomarara miyero uye maratidziro echigadzirwa, ayo anowanzo kutsanangurwa mune zvigadzirwa zvehunyanzvi zvinyorwa.Kuti uwane ruzivo, ndapota tarisa kune yepamutemo webhusaiti yeIyo kambani Yantai Linghua New Materials Co., Ltd.
Pakusarudza TPU zvinhu, kuwedzera kuomarara, zvimwe zvinhu zvemuviri, nzira dzekugadzirisa, kuchinjika kwezvakatipoteredza, uye mutengo zvinhu zvinofanirwa kutariswa kuti ive nechokwadi chekuti zvinhu zvakasarudzwa zvinogona kusangana nezvinodiwa zvekushanda kwezvimwe zvikumbiro.
