Ka hoʻomohala ʻana i ka ʻenehana hana o ka ʻili synthetic ecological e pili ana i ka polyurethane wai paʻa kiʻekiʻe.

ʻO ka ʻili synthetic polyurethane kahi mea hou i hoʻomohala ʻia i nā makahiki i hala iho nei.Hana ʻia ia ma ke kumu o ka uhi ʻana i ka polyurethane slurry me ka wehe ʻana o ka cell cell ma ka haʻahaʻa haʻahaʻa o nā lole lole a me nā lole i ulana ʻole ʻia.Eia nō naʻe, ʻo ka hapa nui o nā polyurethanes i hoʻohana ʻia he solvent, a ʻo ka pōʻino i ke kaiapuni a me ke kino kanaka i hoʻokumu ʻia e ke koena DMF a me ka volatilization VOC i ke kaʻina hana ua lilo ia i bottleneck ʻenehana e kāohi ana i ka hoʻomohala ʻana o ka ʻoihana.I kēia manawa, ʻo ka polyurethane i hoʻokumu ʻia i ka wai he mea kūpono loa ia no ka polyurethane e hoʻoheheʻe ʻia, akā ʻo kona mau hemahema he haʻahaʻa haʻahaʻa paʻa, maikaʻi ʻole nā ​​waiwai kino, maʻalahi ka hoʻopili ʻana i ka ʻili o ka uhi ʻana, ke kūpaʻa hydrolysis maikaʻi ʻole, ka volatilization lohi i ke kaʻina hana uhi, a me ka hana haʻahaʻa. pono.
Ma muli o ka manaʻo o ka "'ōmaʻomaʻo a me ke kaiapuni palekana" a me ka hoʻomaikaʻi ʻana i ka waiwai hoʻohui o nā huahana, ua hoʻomohala ka papahana i kahi ʻōnaehana ʻenehana hou no ka hana ʻana i ka polyurethane paʻa kiʻekiʻe a me ka wai a me ka ʻili synthetic ecological e hiki ke pani i ka polyurethane solvent.ʻO ka polyurethane wai paʻa kiʻekiʻe i hoʻolālā ʻia a hoʻomohala hiki ke hōʻemi i ke koena DMF a me ka volatilization VOC mai ke kumu hoʻomohala ʻoiai e hoʻomaikaʻi ana i ka hana o ka uhi.I ka manawa like, no ka mea he nui ka nui o nā hui hydrophilic a me nā microporous i loko o ka kiʻiʻoniʻoni, ʻo ka uhi ʻana he ea maikaʻi a me ka moisture permeability, a he huahana hana maoli.Eia kekahi, ua hoʻololi ʻia ka polyurethane me nā mea nano e hoʻomohala i nā huahana ʻili synthetic polyurethane kiʻekiʻe a me nā hana nui i kūpono i ka noi mākeke, i mea e hoʻomaikaʻi ai i ka waiwai hoʻohui o nā huahana a hoʻoikaika i ka hoʻokūkū mākeke.
Nā mea noiʻi nui:
(1) ʻenehana hoʻomākaukau o ka polyurethane wai paʻa kiʻekiʻe.E like me ke kŘkohu makemakika o ka mānoanoa nui o nā mea spherical, ua ho'omākaukau 'ia kahi polyurethane wai pa'a ki'eki'e me ka hā'awi 'ana i ka nui.Hiki ke hoʻomaikaʻi i ka ʻike paʻa o ka lotion me ka hoʻonui ʻole ʻana i ka viscosity kiʻekiʻe.Hoʻoholo ʻia ka pilikia o ka viscosity kiʻekiʻe a me ka paʻa haʻahaʻa i ka hana ʻana o ka polyurethane waterborne kiʻekiʻe.ʻO ka maʻiʻo paʻa he> 50%, ʻo ka huina pili o ke kiʻiʻoniʻoni he 101.1 °, a hoʻomaikaʻi ʻia ke kūpaʻa wai a me ka hydrolysis.
(2) ʻO ka ʻenehana hana ʻana o ka wai polyurethane foamed bass.Ma muli o ka polyurethane wai paʻa kiʻekiʻe, ua koho ʻia ka hui pū ʻana o nā ʻano hana huʻi kino a me nā kemika e hana i ka bass polyurethane kumu wai me ka cell adjustable.ʻO ka huahana he plump, mānoanoa a palupalu, me ka maikaʻi o ka moisture absorption a me ka permeability, ka loaʻa ʻana o zero VOC a me DMF emissions i ke kaʻina hana, e hōʻemi ana i ka paʻakikī o ka hoʻopau ʻana i ka mālama ʻana a me ka mālama ʻana i ke kumukūʻai o ka hoʻihoʻi ʻana i ka solvent a me ka mālama ʻana i ka pae hope.
(3) ʻenehana hoʻomākaukau o ka polyurethane wai.Ua hoʻomākaukau ʻia ka polyurethane waterborne multifunctional me ka super hydrophobicity, ke kūpaʻa a me nā waiwai anti-static ma o ka hoʻohana ʻana i ka mīkini pane kaomi o "mercapto monoene", nanotechnology a me ka ʻenehana mālama māmā.Hiki ke hoʻohana ʻia i ka ʻili synthetic, ka uhi textile, ka hoʻokaʻawale ʻana i ka aila-wai, ka pale electromagnetic a me nā māla ʻē aʻe.
