Elastomers a me kā lākou noi.

ʻO nā polyurethane elastomers e pili ana i ka hui o nā plastics, ka mea i haku ʻia ma muli o ka polymerization, a me nā kaula nui o lākou nā pūʻulu urethane. Ua kapa ʻia ʻo PUR a ʻo PU paha, he nui ko lākou waiwai i hoʻopaʻa ʻia. ʻO kā lākou pono a me ke kumukūʻai kūpono loa e hana i ka elastomers i hoʻohana pinepine ʻia i nā hana lehulehu.

Nā huahana Elastomer:
ʻO nā kumuwaiʻa PUR nā mea like-rubber. Mai ka huʻu ʻokoʻa lākou, ʻokoʻa pū kekahi i loko o ia mea ua ʻoi aku ka maikaʻi o ka kino a me ka ʻikaʻona ma mua o ka hana. Eia kekahi, hiki ke hoʻohālikelike i nā waiwai o polyurethane elastomers i kahi ākea ākea. Ma ka hoʻomaʻamaʻa, ʻo kēia ka mea o PU he kumu maʻamau

Loaʻa i kona mau pōmaikaʻi nui kahi hoʻokūkū kiʻekiʻe, ke hoʻokō nei i kona mahalo i kona kū ʻana i ke kiʻekiʻe.

ka hana a nā mea kemikela e like me ka ʻenehana, nā mākeke, nā aila, nā paʻakai, ka waikahele a me ke kō, ka paakai ngima a i ʻole ka wai paʻakai; i nā mea ʻē aʻe, hiki i nā huahana PU ke hana i loko o kahi kahua nona pH ma waena o 5 a 12.
nā umu a me nā kūlana ʻē aʻe i ka wā.
abrasion,
ka pālahalaha ʻana, ka ʻīwī a me nā puʻupuʻu - nā huahana i hana ʻia me ka plastik PUR i kūleʻa i ka mahana mai nā -40 ° C a i 80 ° C,
elemakule.
He aha nā hiʻohiʻona e kū ai ka polyurethane elastomers? He pono maoli e haʻi ʻia i ʻaneʻi: aia kekahi:

pakiko-kinai pū
papa,
ole-omaka,
ʻeono mau māmā ma mua o ke kila.
Eia kekahi, ʻo nā huahana i hanaʻia i nā huahana PUR maikaʻi loa i nā waiwai kahalulu haʻalulu maikaʻi a hiki ke hoʻohana i nā kūlana maloʻo a maloʻo hoʻi. ʻO ka mea hope loa, ʻike ʻia lākou i kahi ākea a me ka palahalaha a me ka laulā o ka paakiki, ʻaʻole ia e pale i ka nui o ka elongation.

He aha ka hoʻohana o plastics PUR?
Hoʻohana pinepine ʻia ka Polyurethane elastomers, ma waena o kekahi i ka mīkini, nā hana ʻenehana a me nā palapala. A me he mea laikini like ʻole, me nā waiwai i ʻoi aku ka maikaʻi o nā mea ʻoi aʻe, he mea maikaʻi loa ia no ka hoʻopili ʻana i nā huahana like:

gaskets,
membranes,
nā huakaʻi paʻi ʻana
piula kolo,
wili hale ʻaihana
scrapers
pahi kaua, pahu paʻa a me nā ʻili no nā ʻano o nā mīkini ʻenehana,
nā mea hele, nā pale anti-vibration a me nā mea hoʻonaninani ʻē aʻe,
kaʻaahi hoʻokaumaha kaʻa.
E like me kāu e ʻike ai, nui ka hana o polyurethane elastomers i ka ʻoihana, he ākea ka nui o kā lākou hoʻohana.
