ʻO nā mea hoʻoheheʻe amphoteric moʻo Betaine he mau mea hoʻoheheʻe amphoteric i loaʻa nā ʻātoma N alkaline ikaika.He mau paʻakai kūʻokoʻa maoli lākou me ka laulā isoelectric ākea.Hōʻike lākou i nā hiʻohiʻona dipole ma kahi ākea.Nui nā hōʻike e loaʻa ana nā surfactant betaine ma ke ʻano o ka paʻakai kūloko.No laila, ua kapa ʻia ia i kekahi manawa he quaternary ammonium internal paʻakai surfactant.E like me nā mea lawe kikowaena hoʻopiʻi maikaʻi ʻole, hiki ke hoʻokaʻawale ʻia nā betaine surfactants i hōʻike ʻia i ka noiʻi o kēia manawa i carboxyl betaine, sulfonic betaine, phosphoric betaine, etc.

ʻO nā mea hoʻoheheʻe amphoteric betaine series he mau paʻakai kūʻokoʻa me ka laulā isoelectric ākea.Hōʻike lākou i nā hiʻohiʻona dipole i kahi ākea pH ākea.Ma muli o ka noho ʻana o ka quaternary ammonium nitrogen i loko o nā molekala, ʻo ka hapa nui o nā surfactant betaine he paʻa kemika maikaʻi i ka media acidic a me ka alkaline.ʻOiai ʻaʻole i loaʻa i ka mole i nā pūʻulu hana e like me ka paʻa eter a me ka paʻa ester, ʻoi aku ka maikaʻi o ke kūpaʻa oxidation.

He mea maʻalahi ka hoʻoheheʻe ʻana i nā surfactants amphoteric betaine series i ka wai, i loko o nā ʻakika a me nā kumu paʻa, a me nā hoʻonā paʻa o nā paʻakai inorganic.ʻAʻole maʻalahi lākou e hana me nā metala honua alkaline a me nā ion metala ʻē aʻe.He maʻalahi ka hoʻoheheʻe ʻana i ka betaine kaulahao lōʻihi i loko o ka wai wai a ʻaʻole pili i ka pH.Hoʻopili nui ʻia ka solubility o ka betaine e ka nui o nā mana kalapona.Hiki ke hiki i ka 35% ka nui o ka lauramide propyl betaine sx-lab30 i hoʻoheheʻe ʻia i loko o ka wai, akā haʻahaʻa loa ka solubility o nā homologues me nā kaulahao kalapona lōʻihi.

Hōʻike ʻia ke kūpaʻa wai paʻa o nā surfactants i ko lākou ʻae ʻana i nā ion paʻakikī calcium a me ka magnesium a me ko lākou mana hoʻopuehu i ke kopa calcium.He nui nā betaine amphoteric surfactants e hōʻike ana i ke kūpaʻa maikaʻi loa i nā ion calcium a me ka magnesium.Paʻa ka paʻa o ka ion calcium o ka hapa nui o nā surfactants sulfobetaine amphoteric, ʻoiai ʻoi aku ka haʻahaʻa o ka waiwai kūpaʻa calcium o nā pūhui amine lua e pili ana.

He waiwai nui nā mea hoʻohāhā betaine series amphoteric surfactants.Ma hope o ka hui pū ʻana me nā surfactants anionic, pili ikaika nā molekala.Hoʻonui nui ʻia ka hopena o ka hoʻoulu ʻana a me ka hoʻopili ʻana.Eia kekahi, ʻaʻole pili ʻia nā waiwai o ka beet beet surfactants e ka paʻakikī o ka wai a me ka PH o ka waena.Hoʻohana ʻia lākou e like me nā mea hoʻoulu a i ʻole foamers, a hiki ke hoʻohana ʻia i kahi ākea o PH.
