【Hana】2,4,7,9-Tetramethyl-5-decyne-4,7-diol ʻO ka huahana surfactant kahi mea hoʻohui nui me ka pulu, de-foaming a me ka hoʻopuehu ʻana. ʻO ka huahana he symmetrical non-ionic surfactant. ʻO kāna ʻano kemika gemini kūʻokoʻa e hiki ai i ka huahana ke hōʻemi i ka haʻalulu o ka ʻili, hoʻomalu i ka ʻūhā, a hoʻemi i ka ʻike wai. Hiki ke hoʻohana ʻia i loko o nā ʻoihana he nui: e like me ka uhi ʻana i ka ʻoihana wai, ka pena lāʻau wai, ka pena plastik wai, ka inika wai, OPV, ka hoʻopili ʻana i ka puʻuwai, ka puaʻa a me ka hana dye, ʻoihana hana metala, flux , pesticides, etc.
Holo wikiwiki ia, hoʻemi i ka neʻe ʻana o ka ʻili a me ke kuʻekuʻe o ka ʻili, defoams a keʻakeʻa i ka huʻuha, haʻahaʻa ka ʻike wai, hiki ke pulu i nā ʻano substrates, ʻaʻole i hana i nā micelles, maikaʻi ke kūpaʻa wela, a maikaʻi ke kūpaʻa acid-base. ʻOi aku ka kiʻekiʻe o nā ʻōnaehana wai hoʻomaʻemaʻe ma mua o nā ʻōnaehana solvent a pono e hoʻohui i nā surfactant e hoʻomaikaʻi i ka pulu. Eia nō naʻe, ʻo nā mea pulu maʻamau e hana i ka huʻa a me ka hoʻopaʻa ʻana i ka huʻa. Inā hoʻohui ʻia nā defoamers, e ʻike hou ʻia nā pilikia pulu ʻino e like me nā pinholes.
Hiki iā ia ke pale i kēia mau pilikia. ʻOi aku ka maikaʻi o ka hana ma mua o nā surfactants kuʻuna, a hiki iā ia ke hāʻawi i ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka hoʻopau ʻana i ka pua ma lalo o nā kūlana ikaika.
Ma muli o kona ʻano molekala kū hoʻokahi, ʻo ka defoaming i nā surfactants moʻo huahana he mea hoʻoheheʻe ʻole ionic maikaʻi.
ʻAʻohe wahi ao o ka surfactant a hiki ke loaʻa nā waiwai defoaming lōʻihi ma kahi ākea ākea. ʻIke wai He nui nā surfactants e hoʻopilikia i ka ʻike wai ma ka ʻili i uhi ʻia ma hope o ka maloʻo ʻana.
ʻO nā surfactants hydrophilic kiʻekiʻe e like me anionic (dioctyl sulfosuccinate sodium salt) a i ʻole polyethoxylated surfactants e hiki ke hoʻoheheʻe hou ʻia i loko o ka wai, e hoʻopilikia ai i ka ʻili o ka uhi maloʻo, e like me ka paʻa, ka lauoho keʻokeʻo, ka fogging, a me ka pale ʻana i ka wai.
Manaʻo ʻia e hoʻohui i ka emulsion a i ʻole resin a me nā surfactants ʻē aʻe ma mua, a laila e hoʻohui i ka 2,4,7,9-Tetramethyl-5-decyne-4,7-diol series surfactants. ʻO kēia ka mea e hōʻoia ai i ka hoʻopuehu nui ʻana i loko o ka ʻōnaehana, e koi ana i ka hoʻopuehu piha no 15 -30 minuke. Hiki i kekahi mau surfactant series 2,4,7,9-Tetramethyl-5-decyne-4,7-diol ke crystallize i ka wā o ka lawe ʻana a i ʻole ka mālama ʻana i nā haʻahaʻa haʻahaʻa loa; Hiki ke hoʻihoʻi maikaʻi ka hoʻomehana ʻana i ka wā liʻiliʻi.
Manaʻo ʻia ka pae hoʻohui hoʻohana:
Ka uhi wai: 0.1%—3.0%
ʻO nā mea hoʻopili pili wai: 0.1%—1.0%
ʻO ka hopena punawai: 0.1%—1.0%
Inika mokulele: 0.1%—1.0%
ʻO ka ʻikepili ma luna nei ka nui empirical, a ʻo ka dosage maikaʻi loa e hoʻoholo ʻia e nā ʻano hoʻokolohua
Pono:
E laha koke, e hoemi ana i ka ikaika a me ka static o ka ili, defoaming, a me ka antifoaming, haʻahaʻa wai, hoʻomaʻemaʻe i nā substrate me ka hana ʻole ʻana i nā micelles.
pulu:
ʻO nā ʻōnaehana wai i ʻoi aku ka kiʻekiʻe o ka ʻili ma mua o nā ʻōnaehana solvent, a pono e hoʻohui i kahi surfactant e hoʻomaikaʻi i ka wettability. Hiki i nā huahana series ke lanakila i kēia mau pilikia, hāʻawi i ka hana ʻoi aku ka maikaʻi i ka hāʻawi ʻana i ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka defoaming ʻoiai ma lalo o nā kūlana ikaika.
Hoʻoheheʻe ʻia:
ʻO nā surfactants moʻo, me kā lākou ʻano molekala kū hoʻokahi, hana ma ke ʻano he symmetric non-ionic defoaming agents maikaʻi loa. Hōʻike lākou i nā waiwai defoaming hoʻomau ma luna o kahi ākea ākea me ka ʻole o ke ao.
ʻIke wai:
ʻO ka nui o nā surfactants ke kumu o ka naʻau o ka wai ma ka ʻili o ka uhi maloʻo. ʻO nā surfactants hydrophilic kiʻekiʻe e like me anionic (dioctyl sulfosuccinate) a i ʻole polyethoxylate surfactants hiki ke hoʻololi maʻalahi i ka wai, e hoʻopōʻino ai i ka ʻili o nā uhi maloʻo e like me ka paʻa a me ke keʻokeʻo, ka atomization, a me ka pale ʻana i ka wai.
