Ke kūʻai aku nei i ka ʻono polyether polyurethane acrylate no ka lāʻau, ka pepa a me nā uhi ʻili

ZCʻO 6203 kahi polyether type polyurethane acrylate.Hoʻopau ʻia ka polyether polyol ma ke ʻano he polyether.He oligomer ia me ka paʻa eter (- ror -) ma ke kaulahao nui a ʻoi aku ma mua o ʻelua mau pūʻulu hydroxyl (- OH) i ka hui hope a i ʻole hui ʻaoʻao.Hoʻomākaukau ʻia ia e ka polymerization o ka mea hoʻomaka (hui pū me ka pūʻulu hydrogen ikaika) me ka ethylene oxide (EO), propylene oxide (PO), epoxy butane (Bo) i mua o ka catalyst.ʻO ka puka nui loa o ka polyether he glycerol (glycerol) ma ke ʻano he mea hoʻomaka a me ka epoxide.Hoʻopuka ʻia nā polyol polyether maʻamau ma o ka hoʻololi ʻana i ke ʻano hānai (hui ʻia a ʻokoʻa paha), ka lākiō a me ke kauoha hānai ʻana o Po a me EO.

ʻO kāna helu ʻenehana: viscosity ʻo 40000-70000pa S / 25℃, waiwai waika < 0.5 (NCO%), hana 3 (waiwai theoretical), wai aniani ʻole a melemele paha ke nānā aku;Loaʻa i kēia huahana nā mea maikaʻi o ka paʻakikī maikaʻi, ka ikaika kiʻiʻoniʻoni kiʻekiʻe, ka hana hoʻokō kiʻekiʻe, paʻa paʻa a pēlā aku.Hoʻohana nui ʻia ia i ka ʻīnika hoʻomaʻamaʻa māmā, nā lako lāʻau, ka uhi ʻana i ka papahele, ka uhi ʻana i ka pepa, ka uhi ʻana i ka plastic, ka hoʻoheheʻe ʻana, ka ʻili metala a me nā māla ʻē aʻe.

Aia i loko o ke kaulahao nui o zc6203 ka pilina eter (- ror -), a ʻo ka hui hope a i ʻole ka ʻaoʻao ʻaoʻao aia nā oligomers me nā hui hydroxyl ʻoi aku ma mua o 2 (- OH).Hoʻokumu ʻia ia e ke apo polymerization wehe o nā polyols haʻahaʻa molekala kaumaha, polyamines a i ʻole nā ​​pūhui i loaʻa ka hydrogen ikaika me nā olefins oxidized ma lalo o ka hana a nā catalysts.He propylene oxide (propylene oxide) a me ka ethylene oxide (ethylene oxide) ka nui o nā olefins, a ʻo ia ka propylene oxide ka mea nui loa.ʻO ke kaumaha mole o ka polyether me ka hydroxyl-propylene glycol a me ka tetrahydroxy-propylene glycol i ka hoʻohana maʻamau ʻo 4000-400.ʻO nā resins polyether i hoʻohana ʻia e like me nā adhesives e hoʻoneʻe i ke koena o nā catalysts alkaline i ka wā polymerization, no ka mea hiki iā lākou ke catalyze i ka dimerization o isocyanates a hoʻopilikia i ka maikaʻi o nā adhesives.
