E ʻike i kahi ʻano ʻē aʻe o ka mīkini hoʻoheheʻe polyurethane

I ka ʻimi ʻana i nā ʻano huila urethane like ʻole, pono mākou e haʻi i ko lākou mau ʻano kūikawā a me nā hiʻohiʻona noi. ʻO ka Polyurethane ma ke ʻano he mea hana kiʻekiʻe. Me kona mau waiwai kino a me nā kemika maikaʻi loa. Noho ia i kahi kūlana koʻikoʻi ma ke kahua o ka hana ʻana i nā huila.

ʻO ka mea mua. E nānā kākou i nā huila polyurethane (TPU). Loaʻa i kēia mau huila kahi ʻiwi polypropylene a nylon paha. Ma o ka ʻenehana hoʻoheheʻe injection lua, ua hoʻokumu ʻia ka ʻili huila polyurethane A ma ka ʻaoʻao o waho o ke kumu. ʻAʻole wale nā ​​​​huila TPU i nā waiwai o ka pale ʻana i ka papahele, ka omo ʻana i nā haʻalulu, ʻaʻole e hōʻailona a ʻaʻole e waihoʻoluʻu. Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka friction a me ka corrosion. Hiki ke ʻōwili maʻalahi ma nā ʻano ʻili like ʻole. Eia kekahi. Hiki ke hoʻololi ʻia kona kala e like me ke koi. Hoʻololi i nā pono o nā hanana like ʻole. Eia naʻe. He mea kūpono ke hoʻomaopopo ʻana i loko o kahi ʻano wela. E hoʻemi ʻia ka hiki ke ukana o ka huila TPU.

ʻO ka hana aʻe, ʻo ia ka ninini ʻana i kahi huila elastomer polyurethane (CPU). He hao a alumini paha ko kēia mau huila ma ke ʻano he kumu. Nā elastomers polyurethane thermosetting i hoʻoheheʻe ʻia e ka hopena kemika. Hoʻokumu i kahi ʻili huila ma hope o ka hoʻōla ʻana i nā mahana kiʻekiʻe. Loaʻa i nā huila CPU nā pono like o ka pale papahele, ʻaʻohe māka a me ka ʻole o ka staining. He kūpaʻa UV a kūpaʻa hoʻi i ka friction, e kūpono ana no nā noi e pono ai ke kiʻekiʻe o ka ʻoluʻolu hana. Eia naʻe. ʻAʻole ia e kū i ka wai wela, ka mahu wai, a pēlā aku ... No laila pono ke akahele i ka wā e hoʻohana ai iā ia i nā wahi kikoʻī.

E kamaʻilio kākou e pili ana i kahi huila polyurethane (CPU) ʻē aʻe. Hoʻokumu ʻia kēia mau huila ma luna o nā elastomers polyurethane thermoset i hoʻoheheʻe ʻia i ka hopena kemika. Loaʻa nā pono e like me nā mea o ka huila CPU i wehewehe ʻia ma luna, ʻo ia hoʻi e pale i ka papahele, e kūʻē i ka friction, a pēlā aku. He mea nui loa ia. He haʻahaʻa loa kona deformation mau loa, ʻo ke kū'ē ʻōwili haʻahaʻa. Hiki ke kū i nā ukana dynamic i nā wikiwiki kiʻekiʻe. Kūpono no ka hoʻohana ʻana i nā kūlana wikiwiki kiʻekiʻe.

ʻO ka mea hope loa. E nānā kākou i ka huila polyurethane foamed (PUE). Me kona ʻano microporous kū hoʻokahi, hōʻike kēia huila i nā waiwai e like me ka haʻahaʻa haʻahaʻa, ke kaumaha māmā a me ka maʻalahi o ka hoʻololi ʻana. Loaʻa iā ia nā ʻano waiwai maikaʻi loa e like me ke kaumaha kiʻekiʻe, ka elasticity kiʻekiʻe a me ke kū'ē pelu. ʻO kēia mau waiwai o nā huila PUE e hoʻolilo iā lākou i koho kūpono no nā mea casters. Inā he leo a me ka ikehu omo a i ʻole ka damping a me ka cushioning haʻalulu. Hiki iā lākou āpau ke hōʻike i ko lākou mau pono kūikawā.

Ma keʻano holoʻokoʻa. ʻO nā huila Polyurethane, me kā lākou hana koʻikoʻi a me nā ʻano like ʻole o ia mea, hoʻohana nui ʻia ia ma nā ʻano like ʻole. Mai nā huila TPU e pale ana i ka honua a hoʻopili i ka haʻalulu. a i ke kūpaʻa UV a me ka friction o ka huila CPU. eia hou aʻe i ka haʻahaʻa haʻahaʻa a me ke kaumaha māmā o ka huila PUE. pāʻani kēlā me kēia ʻano huila polyurethane i kahi kuleana koʻikoʻi ma kāna kahua ponoʻī. ke koho ʻana i ka huila urethane kūpono no kāu mau pono. ʻaʻole wale ia e hoʻonui i ka pono. hāʻawi pū ia i kahi ʻike ʻoluʻolu a palekana hoʻi.
