E hoʻohana i kēia mau ala 7 e ʻike ai i ka TPE a me ka TPU!

Ke ʻōlelo ākea nei ʻo TPE i ka huaʻōlelo maʻamau no nā elastomers thermoplastic āpau.Hoʻokaʻawale ʻia e like me kēia:

Akā ʻo ka mea maʻamau i kapa ʻia ʻo TPE kahi hui o SEBS/SBS+PP+naphthenic oil+calcium carbonate+auxiliaries.Ua kapa ʻia ʻo ia ʻo ka palaka palupalu kūlohelohe i ka ʻoihana, akā i kekahi manawa ua kapa ʻia ʻo TPR (ua kapa ʻia ʻo ia ma Zhejiang a me Taiwan) ).ʻO TPU, i kapa ʻia he polyurethane, ʻelua ʻano: polyester type a polyether type.

ʻO TPE a me TPU nā mea thermoplastic me ka elasticity rubber.ʻO nā mea TPE a me TPU me ka paʻakikī like hiki ke paʻakikī ke hoʻokaʻawale ma waena o TPE a me TPU ma ka nānā wale ʻana iā lākou me ka maka ʻōlohelohe.Akā e hoʻomaka ana me nā kikoʻī, hiki iā mākou ke nānā i nā ʻokoʻa a me nā ʻokoʻa ma waena o TPE a me TPU mai nā ʻano he nui.

1. ʻOkoʻa

ʻOi aku ka maikaʻi o ka TPU ma mua o ka TPE, a ʻaʻole maʻalahi ke hoʻopili e like me ka TPE māmā.

2. Pauku

ʻOkoʻa ākea ka māhele o TPE, mai ka 0.89 a i ka 1.3, aʻo ka TPU mai ka 1.0 a i ka 1.4.ʻO ka ʻoiaʻiʻo, i ka wā o kā lākou hoʻohana ʻana, ʻike ʻia lākou ma ke ʻano o ka hui ʻana, no laila e loli nui ka gravity kikoʻī!

3.Oil kū'ē

He maikaʻi ko TPU kūʻē i ka aila, akā paʻakikī no ka TPE ke kūpaʻa ʻaila.

4.Ma hope o ke ahi

He ʻala ʻala māmā ko TPE i ka wā e ʻaʻa ana, a he liʻiliʻi a māmā ka uahi ʻā.He ʻala ʻala ka TPU, a he kani pahū liʻiliʻi ke ʻā.

5. Mechanical waiwai

ʻOi aku ka maikaʻi o ka elasticity a me ka elastic recovery o TPU (ka pale pale a me ka pale kolo) ma mua o TPE.

ʻO ke kumu nui, ʻo ka ʻōnaehana waiwai o TPU he ʻano like ʻole polymer a no ka ʻāpana resin polymer.ʻO ka TPE kahi mea hoʻoheheʻe ʻia me kahi hoʻolālā multi-phase i hōʻuluʻulu ʻia e ka hui pū ʻana.

ʻO ka hana TPE paʻakikī kiʻekiʻe e maʻalahi i ka deformation huahana, ʻoiai ʻo TPU e hōʻike ana i ka elasticity maikaʻi loa i nā pae paʻakikī a pau, a ʻaʻole maʻalahi ka hoʻololi ʻana o ka huahana.

6. Temperature kū'ē

ʻO ka TPE -60 degere Celsius ~ 105 degere Celsius, ʻo TPU -60 degere Celsius ~ 80 degere Celsius.

7. Keʻano a me ka manaʻo

No kekahi mau huahana overmolded, nā huahana i hana ʻia me ka TPU he manaʻo ʻino a me ke kūpaʻa kūʻē ikaika;ʻoiai nā huahana i hana ʻia me TPE he ʻano maʻalahi a palupalu a me ka hana friction nāwaliwali.

I ka hōʻuluʻulu ʻana, ʻo TPE a me TPU nā mea palupalu a loaʻa ka elasticity rubber maikaʻi.I ka hoʻohālikelike ʻana, ʻoi aku ka maikaʻi o TPE ma ke ʻano o ka hōʻoluʻolu tactile, ʻoiai ʻo TPU e hōʻike ana i ka elasticity maikaʻi loa a me ka ikaika.
