Ka hana ʻili a me ke kūpaʻa wai paʻakikī o AES70
ʻO ka waiʻona Aliphatic polyoxyethylene ether sodium sulfate (AES) he ʻano gel keʻokeʻo a melemele paha, maʻalahi ke hoʻoheheʻe ʻia i ka wai. Loaʻa iā ia nā waiwai decontamination, emulsification a me ka foaming maikaʻi loa. Maʻalahi ke biodegrade, ʻoi aku ka nui o ka biodegradation ma mua o 90%. Hoʻohana nui ʻia i ka shampoo, ka wai ʻauʻau, ka mea holoi kīʻaha, ke kopa composite a me nā mea hoʻonani holoi ʻē aʻe; Hoʻohana ʻia i ka ʻoihana lole wetting agent, cleaning agent, etc. Anionic surfactant.
E pili ana i ka hana ʻili a me ke kūpaʻa wai o ka waiʻona momona polyoxyethylene ether sodium sulfate (AES):
1. Hana ʻili o AES:
He ikaika ka mana hoʻomaʻū, emulsifying a me ka hoʻomaʻemaʻe o AES. Haʻahaʻa kona ʻilikai a liʻiliʻi kona ʻano koʻikoʻi.
Hōʻike ka ʻikepili ua hoʻopilikia ʻia ka ʻilikai a me ka ikaika pulu e ka lōʻihi o ke kaulahao kalapona o ka ethylene oxide i hoʻopaʻa ʻia. Hoʻonui ka ʻilikai a me ka ikaika o ka ethylene oxide me ka hoʻonui ʻana o ka helu mole i hoʻohui ʻia. Eia kekahi, i ka piʻi ʻana o ka nui o ka wai, emi ka ʻilikai, akā i ka wā e hiki ai i ke kāpili koʻikoʻi, ʻaʻole e emi hou ka ʻilikai ʻoiai e piʻi ana ka nui. Hoʻonui ka maʻalahi o ka pulu ʻana o ka ethylene oxide i ka wā e piʻi ai ka nui o nā mole i hoʻohui ʻia, a emi iho i ka wā e piʻi ai ka nui o nā mole i hoʻohui ʻia.
2. Ke kūpaʻa wai paʻakikī AES:
He kūpaʻa maikaʻi loa ko AES i ka wai paʻakikī, a maikaʻi loa kona kūlike me ka wai paʻakikī. He kiʻekiʻe loa ka helu kūpaʻa o nā iona calcium a me magnesium, a maikaʻi loa ka hoʻopuehu ʻana o ke kopa calcium.
Wahi a ka ʻikepili i hōʻike ʻia: ʻo ke kaulahao kalapona C12-14 waiʻona AES i loko o ka wai kai 6300ppm, ʻo kona hoʻopuehu ʻana o ka calcium (wai kai) he 8%. I loko o ka wai paʻakikī 330ppm, ʻo kona hoʻopuehu ʻana o ka calcium he 4%. ʻO ka helu kuhikuhi paʻa o ka ion calcium > 10000ppmCaCO3. He kiʻekiʻe loa ka helu kuhikuhi paʻa o ka ion calcium AES, no ka mea, he maikaʻi ka hoʻomanawanui o kona mau mole i nā ion calcium (magnesium), ʻo ia hoʻi, hiki iā ia ke hana i nā paʻakai calcium organik (magnesium) me nā ion calcium (magnesium), a ʻo nā paʻakai calcium (magnesium) a lākou e hana ai he maʻalahi ke hui pū me nā hui hydrophilic a pane e hana i nā hui paʻakai calcium (magnesium) i maʻalahi ke hoʻoheheʻe ʻia. No laila, maikaʻi loa ka solubility wai o AES, a hiki ke hoʻohana ʻia no ka holoi ʻana i ka mahana haʻahaʻa. Hōʻike nā hoʻokolohua he ʻoi aku ka maikaʻi o ka solubility wai o C1-14 waiʻona AES ma mua o ka waiʻona C14-1 a i ʻole 16-18 waiʻona AES. Hoʻonui ʻia ka solubility o AES i ka wai me ka hoʻonui ʻia o ka helu molar o ka ethylene oxide condensed.
