ʻO ka sodium polyacrylate CAS 9003-04-7

ʻO ka sodium polyacrylate kahi pauka keʻokeʻo. ʻAʻala ʻole a ʻono ʻole. hygroscopic loa. He pūhui polymer me nā hui hydrophilic a me ka hydrophobic. Hiki ke hoʻoheheʻe ʻia i loko o ka wai e hana i kahi wai ʻalohi loa, ʻo ka viscosity o 0.5% solution e pili ana i Pa•s, viscous a ma muli o ka hoʻohū ʻana o ka wai (e like me CMC, sodium alginate) i hana ʻia, akā ma muli o ke ʻano ionic o nā hui anionic he nui i loko o ka mole e hoʻonui i ke kaulahao mole, hoʻonui ka hana a me ka viscosity solution. ʻO kona viscosity ma kahi o 15-20 mau manawa o ka CMC a me ka sodium alginate. ʻO ka hoʻomaʻamaʻa ʻana i ka wela, nā paʻakai kūʻokoʻa a me nā ʻakika organik he liʻiliʻi ka hopena i kona viscosity, ʻoiai e piʻi ana ka viscosity alkaline. Hiki ʻole ke hoʻoheheʻe ʻia e like me ka ethanol. ʻAʻole decompose ka wela ikaika a hiki i 300 degere. Hoʻololi liʻiliʻi ka viscosity lōʻihi, ʻaʻole maʻalahi i ka pala. Ma muli o ka electrolyte, hiki ke maʻalahi i ka waikawa a me nā ion metala, a hoʻemi ʻia ka viscosity.
