He aha ka mea uhi uhi PU?

Nā Kumu Polyurethane

Hāʻawi ʻoe PU mea uhi i nā huahana o kēlā me kēia lā. Loaʻa kēia mea mai kahi hopena kemika ma waena o ʻelua mau mea nui: nā diisocyanates a me nā polyols. Ke hui keia mau mea elua, hana lākou i polymer ikaika i kapa ʻia he polyurethane. Hoʻokumu kēia polymer i kahi papa maʻalahi akā paʻakikī e pale i nā ʻili mai ka pōʻino.

Manaʻo kōkua: Hiki iā ʻoe ke noʻonoʻo i ka polyurethane ma ke ʻano he kaulahao i hana ʻia me nā loulou hou. Hoʻohui kēlā me kēia loulou i ka ikaika a me ka maʻalahi i ka huahana hope.

Eia kahi wehewehe maʻalahi o ka hale ʻo ia ka mea e hana pono ai ka mea uhi PU:

Loaʻa iā ʻoe kahi mea kū i luna e ʻaʻahu a haehae. Hāʻawi ke ʻano crosslinked i ka polyurethane i ka mea uhi uhi PU i kona kūpaʻa kaulana a kūʻē i ka wela.

Nā hiʻohiʻona nui o ka PU

Ke koho ʻoe i ka mea uhi uhi PU, pōmaikaʻi ʻoe mai kahi ākea o ʻano pale. Hana kēia mea i mea pale e pale ai i ka ʻili mai ka wai, kemika, a me ka lā. Hoʻohālikelike ʻia me nā ʻāpana ʻē aʻe, Hāʻawi ʻo PU i ka ikaika mechanical kiʻekiʻe a ʻoi aku ka maikaʻi o ka pale ʻana i ka haki. Hiki iā ʻoe ke hauʻoli i ka hana maikaʻi ma nā wahi ʻino a pulu paha.

Eia ke ʻano o ka hoʻohālikelike ʻana o nā mea uhi uhi PU me nā mea uhi polymer ʻē aʻe:

ʻIke ʻoe i nā mea uhi uhi PU i hoʻohana ʻia i nā ʻoihana he nui no kēia mau hiʻohiʻona. ʻo kahi laʻana, loaʻa iā ʻoe ma nā ʻāpana kaʻa, ili hale, a ma na lako hale. ʻO ka versatility o PU ka mea hiki iā ʻoe ke hoʻohana iā ia no ka pale a me ka hoʻonaninani.

• Loaʻa iā ʻoe ka pōmaikaʻi mai nā manawa hoʻōla wikiwiki, e kōkua i ka wikiwiki o ka hana ʻana.
• Loaʻa iā ʻoe ka lōʻihi i hoʻonui ʻia, e hana ana i ka PU kūpono no nā hana koi.
• Hiki iā ʻoe ke koho mai nā formulations he nui, no laila hiki i nā mea hana ke hoʻokō i kāu mau pono kikoʻī.
• Kākoʻo ʻoe i ka hoʻomau, e like me ka hāʻawi ʻana o kekahi mau uhi PU i nā pono kaiapuni.

ʻO nā mea hoʻopili PU ke kū nei i waho no kona lōʻihi. Hiki iā ʻoe ke manaʻo i ka adhesion ikaika, ʻoiai ma hope o ka loaʻa ʻana o ka wai. ʻo kahi laʻana, Mālama ʻia nā uhi polyurethane ma mua o 3.5 ikaika pili MPa mahope 24 mahina i ka wai kai, ʻoiai e hāʻule ana nā uhi acrylic i lalo 2.0 MPa. ʻIke ʻoe i ka liʻiliʻi ma mua 5% poho kaumaha ma hope 1,000 mau hola o ka hoʻolaha kemika. Noho ʻia ka ʻālohilohi ma luna 80% mahope 2,000 hola o ka hoʻoilo, a ʻelua a ʻekolu manawa ʻoi aku ka nui o ke kūpaʻa ʻana ma mua o ka acrylic. Ma luna o ʻelima makahiki, hiki iā ʻoe ke hōʻemi i nā kumukūʻai mālama a hiki i 35% hoʻohālikelike i nā koho ʻē aʻe.

Ke makemake ʻoe i kahi hilinaʻi, mau loa, a hiki ke hoʻololi, Hāʻawi ka mea uhi PU iā ʻoe i ka hana āu e makemake ai. Hiki iā ʻoe ke hilinaʻi iā ia e pale a hoʻomaikaʻi i kahi ākea ākea.

Kaʻina Hoʻouhi Polyurethane

Na Mea Maka no ka PU

Hoʻomaka ʻoe me nā mea he nui mea nui i ka hana pu nā uhi. Hoʻokumu nā Polyols i ka kumu kemika nui o ka pu, a ʻo ka mea maʻamau ʻoe e hoʻopuka mai iā lākou mai nā meaʻai aila. Hiki iā ʻoe ke hoʻohana i nā mea hana hou e like me PET, PU, a me nā ʻōpala PC, nā mea hana i hoʻololi i polyols no nā huahana pu hou. ʻO nā polyols i hoʻokumu ʻia i ka bio mai ka ʻaila meaʻai, cashew nut shell liquid, kanu mauʻu, terpene, lignin, a me nā mea biodegradable e like me ka polylactic acid a me ka polycaprolactone. Kōkua kēia mau koho iā ʻoe e hana i nā uhi polyurethane e kākoʻo ana i ka hoʻomau a hoʻemi i ka hopena o ke kaiapuni.

• Polyols (hoʻokumu ʻia ka ʻaila)
• Mea hana hou (PET, PU, ʻO nā ʻōpala PC)
• ʻO nā polyols pili bio (ʻaila ʻaila, kanu mauʻu, lignin, nā kumu hoʻoheheʻe ʻia)

Pehea i hana ʻia ai ka uhi ʻana o PU

Hoʻopuka ʻoe i nā uhi pu ma o ka hopena kemika ma waena o nā polyols a me nā diisocyanates. Hoʻokumu kēia ʻano i nā loulou urethane, ka mea e hāʻawi i ka polyurethane i kona maʻalahi a me ke kūpaʻa. Hana ʻo Diisocyanates ma ke ʻano he crosslinking agents, hāʻawi i ka ikaika a me ke kūpaʻa i ka huahana pu hope loa.

ʻIke ʻoe i ke koho ʻana i nā mea hoʻomaka e pili ana i ka nā waiwai o nā uhi pu. ʻo kahi laʻana, ʻO ka hana hydroxyl kiʻekiʻe ma ka polyol e hoʻonui i ka paʻakikī o ka hale ma muli o ka hoʻopili ʻana. ʻO ka ratio o ka isocyanate me ka polyol hoʻololi i nā waiwai mechanical a me ka hana wai.

Ke hahai nei ʻoe i kekahi mau mea nui nā ʻanuʻu no ka hana ʻana i nā lole i uhi ʻia i ka polyurethane a me nā huahana pu ʻē aʻe:

1. E hoʻomākaukau i ka lole ma ka hoʻomaʻemaʻe a me ka hoʻopaʻa ʻana.
2. E hoʻopili i ka uhi pu me ka hoʻohana ʻana i nā ʻano hana e like me ka uhi ʻana i ka pahi, lāʻau maloʻo pā, a i ʻole extrusion hehee wela.
