ʻAkika Sulfoisophthalic Monosodium Paʻakai CAS 6362-79-4
ʻO ka paʻakai monosodium waikawa 5-Sulfoisophthalic (CAS 6362-79-4, inoa Pelekania: 5-sulfoisophthalic acid monosodium (paʻakai) he mea hana waena synthetic organik koʻikoʻi, no nā derivatives acid dicarboxylic aromatic i hoʻololi ʻia i sulfonated. Hoʻokumu ʻia kona ʻano molekala ma ka waikawa isophthalic ma ke ʻano he hui makua, me kahi hui waikawa sulfonic (-SO₃H) i hoʻokomo ʻia ma ke kūlana 5 o ke apo benzene a hana i ka paʻakai me ka sodium.
Mai ka manaʻo o nā waiwai kino a me nā kemika, ʻike pinepine ʻia ka paʻakai monosodium waikawa 5-Sulfoisophthalic ma ke ʻano he pauka keʻokeʻo, me kahi kiko heheʻe o 373 ℃. Ma 20 ℃, ʻo kona density he 1.87, a he solubility maikaʻi kona wai (380g/L). Ma 20 ℃, ʻo kona coefficient acidity (pKa) he 4.1, a ma 23 ℃, ʻo kona LogP he -1.7. Ma ke ʻano holoʻokoʻa. He paʻa ke ʻano o ka sodium m-5-sulfonate a maʻalahi hoʻi e hoʻoheheʻe ʻia i ka wai, e kūpono ai no nā hiʻohiʻona noi ʻōnaehana wai.

1. Kahua o nā mea polymer
Hoʻohana ʻia ka paʻakai monosodium 5-Sulfoisophthalic acid ma ke ʻano he monomer copolymer no ka hana ʻana o ka "polyester i hoʻololi ʻia": copolymerized me ka terephthalic acid a me ka ethylene glycol, a ua hoʻokomo ʻia nā hui sodium sulfonate e hoʻomaikaʻi i ka hydrophilicity a me ka dyeability o ka polyester, kahi i hoʻohana ʻia e hana i nā olonā polyester maʻalahi ke dye a me nā uhi polyester wai.
Ka hoʻomākaukau ʻana o ka "resin hoʻololi ion": Hiki ke hoʻohana ʻia nā hui Carboxyl a me nā hui sodium sulfonate e like me nā hui hoʻololi ion no ka hana ʻana i nā resins adsorption ion palupalu i ka wai a me nā metala kaumaha.
2. Kahua paʻi a me ka hoʻoluʻu lole
Ma ke ʻano he "mea hoʻohālikelike": I ka hoʻoluʻu ʻana o nā olonā synthetic e like me ka polyester a me ka nylon, ʻo ka hoʻohui ʻana i ka sodium isophthalic acid 5-sulfonate hiki ke hoʻoponopono i ka nui o ka lawe ʻana o ka dye, pale i ka hoʻoluʻu ʻokoʻa, a hoʻomaikaʻi i ke ʻano like a me ka paʻa o ke kala o ka hoʻoluʻu lole.
3. Ke kahua o nā uhi a me nā mea hoʻopili.
No nā "uhi wai": Ma ke ʻano he mea hoʻohui hana, hoʻomaikaʻi ka paʻakai monosodium 5-Sulfoisophthalic acid i ka hoʻopuehu ʻana a me ke kūpaʻa wai o ka uhi ʻana, hoʻemi i ka delamination o ka uhi ʻana, a hoʻoikaika i ka pipili ma waena o ka uhi ʻana a me ka substrate.
"Pili wai" i hoʻololi ʻia: Hoʻohui ʻia me ka acrylate, hoʻonui ka paʻakai monosodium 5-Sulfoisophthalic acid i ke kūpaʻa ʻana i ka wā a me ka maʻalahi o ka mea hoʻopili, kūpono no nā mea hoʻopili e like me ka lāʻau a me ka palakiko.
