Nā pōmaikaʻi a me nā mea maikaʻi ʻole o ETPU nā pono

ETPU (polyurethane thermoplastic elastomer) he mea wela wela i haku ʻia me nā polyether polyols a me nā polyisocyanates. Eia nā pono a me nā pōʻino o ETPU nā meahana:

pono:

1. ʻO ke kūpaʻa ʻaʻahu ikaika: ETPU ʻoi aku ka ʻoi aʻe o ka paʻakikī a me ka ikaika ma mua o ka lāʻau kuʻuna a me ka plastic, no laila ke kūpaʻa ikaika a paʻa.
2. ʻAla a me ka wai kūpaʻa: ETPU maikaʻi ka ʻaila a me ka wai, a hiki ke hoʻohana ʻia no ka manawa lōʻihi ma nā wahi haʻahaʻa a ʻaila ʻole me ka maʻalahi o ka pōʻino.
3. Hiki maikaʻi ke kaʻina hana: ETPU hiki ke hana ʻia nā mea i nā ʻano like ʻole o nā huahana ma o ka hoʻoheheʻe ʻana, extrusion, calendering a me nā ʻano hana ʻē aʻe, hiki ke hoʻokō i nā pono o nā noi like ʻole.
4. Elasticity maikaʻi: ETPU he elasticity maikaʻi a me ke kūpaʻa, hiki ke hōʻemi pono i ka hopena a me ka haʻalulu, a pale i nā mea mai ka pōʻino.
5. Pili kaiapuni: ETPU mea hiki ke hana hou ia a pili kaiapuni.

keakea:

1. ʻO ke kumu kūʻai kiʻekiʻe: Ke hoʻohālikelike ʻia me ka lāʻau kuʻuna a me nā mea plastic, ETPU ʻoi aku ka pipiʻi.
2. Poor kiʻekiʻe wela kū'ē: ETPU ʻaʻole hiki ke kū i ka hoʻohana lōʻihi i nā wela kiʻekiʻe.
3. ʻAʻole kūʻē i nā kukuna ultraviolet: Ma hope o ka ʻike ʻana i ka lā no kekahi manawa, ETPU e lilo i mea paʻakikī, palupalu, a nalowale kona elasticity.

I ka hōʻuluʻuluʻana, ETPU He nui nā mea maikaʻi, ʻoi aku ka nui o nā noi e koi ai i ka ikaika kiʻekiʻe, ke kūpaʻa ʻaʻahu, a me ka elasticity. Eia nō naʻe, aia kekahi mau hemahema e ʻike ʻia, e like me ke kumukūʻai kiʻekiʻe, ke kū ʻole i ka wela kiʻekiʻe, a me ke kū ʻole ʻana i nā kukuna ultraviolet.
