Quaternized hydroxyethyl cellulose

ʻO ka Quaternized hydroxyethyl cellulose (QHEC) he mana hoʻololi o ka hydroxyethyl cellulose (HEC) i hoʻopili ʻia me kahi pūhui ammonium quaternary.Hoʻololi kēia hoʻololi i nā waiwai o HEC a loaʻa i kahi polymer cationic i loaʻa i ka nui o nā noi, me nā huahana mālama pilikino, textiles, a me nā uhi pepa.

ʻO ka quaternization o HEC e pili ana i ka hoʻohui ʻana o kahi pūhui ammonium quaternary i ka mole HEC, kahi e hoʻokomo ai i kahi uku kūpono i loko o ka polymer.ʻO ka pūhui ammonium quaternary i hoʻohana pinepine ʻia no kēia kumu ʻo 3-chloro-2-hydroxypropyl trimethylammonium chloride (CHPTAC).Hoʻopili kēia pūʻulu me nā pūʻulu hydroxyl ma ka mole HEC, ka hopena i kahi molela QHEC i hoʻopiʻi maikaʻi ʻia.

ʻO kekahi o nā noi mua o HEC i nā huahana mālama pilikino, e like me nā shampoos, conditioners, a me nā huahana styling lauoho.Hāʻawi ʻo HEC i ka hoʻomaʻamaʻa maikaʻi ʻana a me ka detangling waiwai i ka lauoho, e maʻalahi ai ka hui ʻana a me ke ʻano.Hoʻohana ʻia ʻo HEC ma ke ʻano he mānoanoa a me ka rheology modifier i kēia mau huahana, e hāʻawi ana i kahi ʻano nani a hoʻonui i ka hana holoʻokoʻa.

I nā noi textile, hoʻohana ʻia ʻo HEC ma ke ʻano he mea nui no ka pulupulu a me nā fiber maoli.Hiki i ka HEC ke hoʻomaikaʻi i ka ʻoʻoleʻa a me ka pale ʻana o nā lole, e ʻoi aku ka lōʻihi a me ka maʻalahi o ka mālama ʻana i ka wā o ka hana ʻana.Hiki nō hoʻi iā HEC ke hoʻomaikaʻi i ka hoʻopili ʻana o nā kala a me nā mea hoʻopau ʻē aʻe i ka lole, e hopena i nā kala ʻoi aku ka maikaʻi o ka holoi ʻana.

Hoʻohana pū ʻia ʻo HEC i nā uhi pepa e hoʻomaikaʻi i ke kūpaʻa wai a me ka paʻi ʻana o ka pepa.Hiki i ka HEC ke hoʻomaikaʻi i ka hoʻopili ʻana i ka uhi a hoʻemi i ke komo ʻana o ka wai a me ka ʻīnika i loko o nā pepa pepa, e hopena i nā paʻi ʻoi aʻe.Hiki i ka HEC ke hāʻawi i ka ʻoluʻolu maikaʻi o ka ʻili a me ka nani i ka pepa, e hoʻonui ai i kona helehelena a me nā mea hoʻonaninani.

ʻO kekahi o nā pōmaikaʻi koʻikoʻi o HEC ʻo kona ʻano cationic, kahi e hana maikaʻi loa ai i nā formulations i loaʻa nā surfactants anionic.Hoʻohana maʻamau ʻia nā surfactants anionic i nā huahana mālama pilikino, akā hiki iā lākou ke launa pū me nā mānoanoa non-ionic, e like me HEC, a hoʻemi i ko lākou pono.Hiki i ka HEC, ke cationic, ke hana i nā pilina electrostatic ikaika me nā surfactants anionic, e hoʻomaikaʻi i ka mānoanoa a me ka paʻa.

ʻO kekahi pōmaikaʻi ʻē aʻe o ka HEC ʻo ia ka hoʻohālikelike ʻana me nā ʻano mea ʻē aʻe.Hiki ke hoʻohana ʻia ka HEC me nā mea cationic, anionic, a me ka non-ionic me ka ʻole o ka hoʻopili ʻana i kāna hana.ʻO kēia ka mea i hoʻohana ʻia i loko o nā ʻano hana like ʻole a me nā noi.

Loaʻa ka HEC i nā māka like ʻole a me nā viscosities, e pili ana i ka noi kikoʻī a me nā koi hoʻolālā.Hāʻawi ʻia ia ma ke ʻano he pauka i hiki ke hoʻopuehu maʻalahi i ka wai a i ʻole nā ​​​​mea hoʻoheheʻe ʻē aʻe.Hiki ke hāʻawi ʻia ʻo QHEC ma ke ʻano he huahana pre-neutralized a i ʻole ka hoʻoneʻe ʻana iā ia iho, kahi e hoʻopau ai i ka pono o nā ʻanuʻu neutralization hou i ka wā o ke kaʻina hana.

I ka hōʻuluʻulu ʻana, ʻo ka quaternized hydroxyethyl cellulose he mana hoʻololi o ka hydroxyethyl cellulose i hoʻopili ʻia me kahi pūhui ammonium quaternary.He polymer cationic ka HEC i loaʻa i nā ʻano hana like ʻole, me nā huahana mālama pilikino, textiles, a me nā uhi pepa.Hāʻawi ʻo HEC i nā mea hoʻonaninani maikaʻi a me nā waiwai mānoanoa, hoʻonui i ka hana o nā surfactants anionic, a kūpono me kahi ākea o nā mea ʻē aʻe.ʻO ka versatility a me ka hana o HEC e lilo ia i mea waiwai nui i nā ʻano hana like ʻole a me nā noi.
