Ma muli o ka maikaʻi o ka hoʻolālā ʻana o ka organikʻaila silicone, ua hoʻohana nui ʻia i ka hoʻopau ʻana i ka textile softening.ʻO kāna mau ʻano nui: ʻo ka ʻaila silicone hydroxyl mua a me ka ʻaila hydrogen silicone, ʻo ka ʻaila silicone amino lua o ka hanauna, a hiki i ke kolu o ka hanauna ʻaila silicone block.I ka hoʻomaikaʻi ʻana o ka noi o ka poʻe no ka paʻa, ua hoʻomaikaʻi ʻia ka ʻaila silicone organik i mau makahiki.
1.Hydroxyl silicone aila
ʻO ke kumu nui o ka ʻaila silicone hydroxyl he polymer linear me nā hui hydroxyl ma nā ʻaoʻao ʻelua a me ka silica silicon ma ke kaulahao nui.ʻO ke ʻano hana synthesis maʻamau i hana ʻia e ka hydrolyzing polycondensation o dimethyl dichlorosilane.Ma muli o kona ikaika haʻahaʻa haʻahaʻa, polarity nāwaliwali a me ka adsorption nāwaliwali ma ka ʻili o ka substrate, pono ka noi maʻamau o ka ʻaila silicone hydroxyl i kahi paona molekala kiʻekiʻe e loaʻa ka hopena noi maikaʻi.No laila, maʻamau ka ʻaila silicone hydroxyl i hoʻohana ʻia e like me ka hoʻopau ʻanamea palupaluhe polymer me ke kaumaha mole kiʻekiʻe.Aia kahi drawback e like me ka ʻaila silicone, ma muli o ka ikehu haʻahaʻa a me ka dispersibility wai maikaʻi loa, ʻoi aku ka nui o nā emulsifiers a me kahi mīkini ʻoki a me ka dispersing me ka dispersion kiʻekiʻe e pono ai e emulsify a hoʻopuehu iā ia i nā microemulsions maikaʻi.Akā naʻe, ʻaʻole maikaʻi kona kūpaʻa ʻelemakule.E mau ana ka emulsion stratification hanana ma hope o ka manawa lōʻihi.
2.Hydrogen silicone aila
ʻO ke kumu nui o ka ʻaila hydrogen silicone he polysiloxane me ka paʻa silicon-hydrogen i hoʻokaʻawale like ʻia ma ka ʻaoʻao o ke kaulahao oxygen silicon.ʻO nā ʻano hana synthesis maʻamau ka polycondensation hydrolytic o ka methyl hydrodichlorosilane a me ka polymerization wehe ʻana o nā kino apo hydrosiloxane.No ka mea ʻilihune ka paʻa o ka paʻa silicon-hydrogen, maʻalahi ka dehydrogenate a no laila maʻalahi ke adsorb me nā hui polar ma nā mea textile.No laila, ʻoi aku ka maikaʻi o ka waiwai adsorptive.Loaʻa iā ia ka hana hoʻohana maikaʻi ma nā fiber cellulose a me nā fiber protein, aʻo ka hopena maikaʻi ʻole i nā fiber kemika.E like me ka aila silicone hydroxyl, ʻaʻole maikaʻi kāna hana emulsifying a maikaʻi ʻole kona kūpaʻa.Inā kiʻekiʻe loa ka maʻiʻo hydrogen i ka wā e noi ai, maʻalahi ke alakaʻi ʻana i ke kiʻekiʻe o ka maʻi hydrogen striped, he mea pōʻino i ke kaiapuni kiʻekiʻe ke hoʻonohonoho.
3.ʻO ka ʻaila silicone amino
ʻO ke kumu nui oʻaila ʻaila amino silicone ii ka polysiloxane i loko o ka hui amino ma nā ʻaoʻao ma hope o ka polymerization ma ka hoʻohui ʻana i ka mea hoʻohui amino silane.Hoʻomaikaʻi maikaʻi ʻia ka palupalu a me ka wai o ka polysiloxane ma muli o ka adsorption maikaʻi a me ka hiki ke hoʻopaʻa ʻia o ka hui amino i ka lole a me ka polarity maikaʻi.ʻOi aku ka maikaʻi ma nā lole o ka cellulose fibers, loaʻa iā ia ka hopena noi maikaʻi loa.Ma ka hoʻoponopono ʻana i ka waiwai ammonia, hiki ke hoʻoponopono ʻia ke ʻano o ka hui hui amino silane a me ke kaumaha mole o ka ʻaila silikoni amino.Hiki iā ia ke hoʻomākaukau i nā hopena noi waiwai.Eia nō naʻe, no ka mea, ʻo kāna kaulahao nui he ʻano siloxane, no laila pono ʻoi aku ka mea emulsifying e hoʻokō i ka hopena emulsifying maikaʻi.I ka manawa like, no ka mea he kiʻekiʻe ka hana amino o ka ʻaila silicone amino a aia nō hoʻi ma ka iwi ʻaoʻao.No laila paʻakikī ke wehe ʻana mai ka lole ma hope o ka adsorption.He mea paʻakikī ia e wehe i ka lole lole a me ka hoʻopau ʻana i ka wā e pono ai e hoʻololi i ke kala, e hoʻopau i nā wrinkles a i ʻole nā kiko silicone.ʻO ke kūʻē ʻana i ka wai paʻakikī a i ʻole ka wai alkali o kāna emulsion ua nāwaliwali.
4.Paʻa i ka ʻaila silicone
ʻO ke ʻano nui o ka aila silicone block i loko o ke kaulahao nui o polysiloxane ua hoʻopili ʻia, hoʻopaʻa ʻia a polymerized me kekahi mau ʻāpana kaulahao polyether hydrophilic.Ma ke ala o ka pale ʻana, forging a polymerizing me ka amino chain segment, e hoʻomaikaʻi i ka hana hydrophilic a me ka emulsifying waiwai o siloxane.Ma ka hoʻoponopono ʻana i ka lakio, nā ʻano a me ke kaumaha molekala o ʻekolu mau kaulahao, hiki ke hoʻomākaukau i nā huahana hou aʻe.No kona ʻoi aku ka maikaʻi o ka hydrophilic permeability, ʻoi aku ka maikaʻi no ka hoʻopau ʻana i ka palupalu no nā fiber kemika, me ka hana ʻoi aku ka maikaʻi o ka hoʻololi ʻana i ke kala a me ka wehe ʻana.No ka mea, no ka ammonia ka hui amino, ka ammonia tertiary a me ka ammonia quaternary, ʻaʻole maʻalahi ka melemele.He mea hoʻoluliluli kaulana ia i ka noiʻi hoʻololi i kēia mau lā.
