Hōʻike ʻia ke ʻano o ka hoʻomohala ʻana o nā mea hoʻopili synthetic i ka honua e ka mālama ʻana i ke kaiapuni a me ka hana kiʻekiʻe, me ka piʻi ʻana o nā hoʻoponopono palekana kūlohelohe, hoʻomohala ikaika nā ʻāina i kūkulu ʻia i ka wai. Ma muli o ka hoʻokō piha piha ʻana o ka wai polyurethane adhesives, ʻokoʻa ia i nā ʻano adhesives waterborne a pau, a ua loaʻa ka nānā nui ʻana ma ka home a ma waho i nā makahiki i hala iho nei, ʻoi aku ka hoʻomohala ʻana a me ka noiʻi ʻana o nā mea hoʻopili polyurethane wai kiʻekiʻe i lilo i wela. kumuhana.
ʻO ka wai polyurethane resin (PUD) he emulsion like ʻole i hana ʻia e ka hoʻopuehu ʻana i ka polyurethane i loko o ka wai, nona nā mea maikaʻi o ka haʻahaʻa VOC, haʻahaʻa haʻahaʻa, non-combustible, maikaʻi nā waiwai mechanical, hana maʻalahi a me ka hana ʻana. Hiki ke hoʻohana nui ʻia ka PUD i nā adhesives, synthetic leather, coatings, inks a me nā ʻoihana ʻē aʻe.
ʻO ka wai polyurethane resin e like me ka hoʻohana paʻa ʻana, me ka maʻalahi o ka hoʻoulu ʻana, ke kūpaʻa wela maikaʻi loa a me nā ʻano ʻē aʻe, hiki ke hoʻohana ʻia no nā ʻano like ʻole o ka substrate hoʻopaʻa ʻana, hoʻohana nui ʻia i ke kālu kāmaʻa, ke kāpili kūloko automotive, ka plastic vacuum, adhesive woodworking a me nā māla ʻē aʻe, U1115H, U1115, U1115L he ekolu anionic waterborne polyurethane dispersions, nona ka U1115H. kūpono loa no nā hi'ohi'ona noi'i kū'ē wela ki'eki'e, kūpono loa ka U1115L no nā hi'ohi'ona me nā koi viscosity ki'eki'e.
ʻO ka polyurethane wai ka nui o nā waiwai kino ma hope o ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, me ke kū anuanu maikaʻi, ka pale ʻana i ka solvent, ka hoʻokumu ʻana i ke kiʻiʻoniʻoni, ke kūpaʻa tortuous, ka pale maloʻo a me ka pulu maloʻo, adhesion a me nā pono ʻē aʻe, hiki ke hoʻohana ʻia e like me ka uhi ʻana o nā substrates like ʻole, hoʻohana nui ʻia. i loko o ka ʻili hoʻopau hope, ka uhi lole, ka ʻili synthetic a me nā māla ʻē aʻe.
I ka pōkole, ma muli o ka nui o nā pono o ka wai polyurethane adhesives, ua ʻoi aku ka nui o kā lākou hoʻohana ʻana, a ʻoi aku ka nui o nā ʻano. Wahi a ka wānana a nā poʻe loea e pili ana, ʻo ka noi no nā adhesives synthetic ma Kina he mākeke ākea, a ua lanakila nā polyurethane adhesives wai i ka mākeke me kā lākou hana ʻoi aku ka maikaʻi a me ka mālama ʻana i ka ikehu a me ka mālama ʻana i ka ikehu, a ʻo kā lākou hana a me ka hoʻohana ʻana e hoʻonui wikiwiki a hoʻolaha. . ʻOiaʻiʻo, pono e hoʻoponopono hohonu ʻia kona mau hemahema. China e kālele ana ma luna o ka hooulu ana o waterborne polyurethane adhesives, a e hoʻolauna kī lako ma muli o ka 'ike loea hoʻomohala 'ana i ka "'ōmaʻomaʻo" hoʻoheheʻe-ma muli, 'ole melemele-ʻano, kiʻekiʻe-wela a me ka kiʻekiʻe-hana PU adhesives; E hoʻomohala i ka puʻupuʻu hoʻoheheʻe wela PU reactive, kiʻekiʻe-hana PU structural adhesive a me ka wai haʻahaʻa polymer polyisocyanate adhesive, i hiki i ka pae holoʻokoʻa o PU adhesive ma Kina ke hiki i ka pae kiʻekiʻe o ka honua.
