ʻAʻahu ua TPU

Loaʻa i ka TPU ka ikaika tensile kiʻekiʻe maikaʻi loa, ka ikaika tensile kiʻekiʻe, ka paʻakikī a me nā waiwai anti-kahiko, a he mea palekana kaiapuni makua. ʻO ia hoʻi, ʻo ka ʻaʻahu ua TPU kahi ʻano ʻaʻahu ua i makemake ʻia e ka lehulehu i kēia mau lā. Ke kūpaʻa anu kupaianaha: He haʻahaʻa ka mahana hoʻololi aniani o ka TPU, e mālama ana i ka elasticity maikaʻi, ka maʻalahi a me nā waiwai kino ʻē aʻe ma -35 degere Celsius.

Hoʻolauna

ʻO TPU kahi pōkole o Thermoplastic Urethane, i kapa ʻia ʻo thermoplastic polyurethane elastomer ma ka ʻōlelo Kina. ʻO TPU kahi mea polymer i hana ʻia mai nā molekala diisocyanate e like me diphenylmethane diisocyanate (MDI) a i ʻole toluene diisocyanate (TDI) a me ka polyol molekala nui a me ka polyol molekala haʻahaʻa (chain extender), i polymerized pū ʻia i loko o kahi hopena.

He ikaika kiʻekiʻe ko TPU, ikaika kiʻekiʻe, paʻakikī a me ke kūpaʻa ʻelemakule, a he mea palekana kaiapuni makua. ʻO ia hoʻi, ʻo ka ʻaʻahu ua TPU kahi ʻano ʻaʻahu ua i makemake nui ʻia e ka lehulehu i kēia lā.

Nā kumu no ke koho ʻana i ka mea TPU

ʻO ka ʻaʻahu ua TPU kahi ʻano hou o ka ʻaʻahu ua palekana i ke kaiapuni, a ʻo ke kumu hoʻohālike pono e pili ana i ke kahua loea o nā huahana ʻaʻahu ua. ʻO ka mea mua, hana ʻia ka mea o ka ʻaʻahu ua me ka mea hiki ke palaho loa, i mea e pale aku ai i ka haumia i ke kaiapuni ma hope o ka hoʻolei ʻia ʻana. Ke hiki ʻole ke hoʻohana ʻia ka ʻaʻahu ua a pono e hoʻolei ʻia, hiki ke kanu ʻia i loko o ka lepo. Ma hope o kekahi manawa, e palaho loa ka mea o ka ʻaʻahu ua, a hiki i nā hua ke ulu a ulu i loko o ka lepo e hana i nā mea kanu, ʻaʻole wale ia e hoʻoponopono i ka pilikia palekana o ke kaiapuni o ka ʻaʻahu ua, akā he hopena nō hoʻi ia o ke kanu ʻana i nā lāʻau a me ka ʻōmaʻomaʻo.
