Ulwakhiwo lwe-fatty amine polyglycerol ether surfactants lulandelayo: Iqela le-hydrophilic likwaqulunqwe ngamaqela e-hydroxyl kunye nee-ether bonds, kodwa ukwenzeka okutshintshanayo kwamaqela e-hydroxyl kunye nee-ether bonds kutshintsha imeko ye-polyoxyethylene ether nonionic surfactants, ezilawulwa zii-ether bonds. Emva kokunyibilika emanzini, ukongeza ekwenzeni ii-hydrogen bonds ezibuthathaka ngee-atom ze-oxygen kwii-ether bonds ezinee-hydrogen atom emanzini afana nala alandelayo, zinokusebenzisana namanzi ngamaqela e-hydroxyl. Ke ngoko, ii-fatty amine polyglycerol ether surfactants zinokufumana ukunyibilika kwamanzi okuhle ngenani elincinci lee-glycidol ezongeziweyo, ngoko ke i-hydrophilicity ye-fatty amine polyglycerol ether surfactants inamandla kakhulu kune-polyoxyethylene ether surfactants. Ukongeza, ii-fatty amine polyglycerol ether surfactants nazo zinesakhiwo se-organic amines, nto leyo eyenza ukuba zibe neempawu ezithile ze-nonionic kunye ne-cationic surfactants: xa inani lezongezo lincinci, zibonisa iimpawu ze-cationic surfactants, ezifana nokumelana ne-asidi kodwa kungekhona ukumelana ne-alkali, kunye neepropati ezithile ze-bacterial; xa inani lezongezo likhulu, ipropati ye-nonionic iyanda, ayisafiki kwizisombululo ze-alkaline, umsebenzi womphezulu awutshatyalaliswa, ipropati ye-nonionic iyanda, kwaye ipropati ye-cationic iyancipha, ngoko ke ukungahambelani ne-anionic surfactants kubuthathaka, kwaye ezi zimbini zinokuxutywa ukuze zisetyenziswe.
1. Isetyenziswa kushishino lokuhlamba impahla
Ii-surfactants ze-fatty amine polyglycerol ether zibonisa iimpawu ezahlukeneyo ezinamanani ahlukeneyo okongeza: xa inani lokongeza lincinci, zibonisa iimpawu zee-cationic surfactants, nto leyo enyusa ukunyibilika kwazo kumaqondo obushushu aphantsi kwaye izinike i-detergent elungileyo kuluhlu olubanzi lobushushu; xa inani lokongeza likhulu, i-non-ionic property iyanda, ngoko ke azisayi kuhla kwizisombululo ze-alkaline kwaye umsebenzi wazo womphezulu uhlala ungonakaliswanga. Ngenxa yokwanda kwe-non-ionic property kunye ne-cationic property enciphileyo, xa zidibene nee-anionic surfactants, zinokunciphisa kakhulu uxinzelelo lomphezulu kwaye ziphucule amandla e-emulsifying kunye nokumanzisa; njengee-polyoxyethylene chains, i-hydrophilicity yazo kunye ne-steric impact effect nazo zinempembelelo ecacileyo yokuthintela ukuna okanye ukuhlangana kweesepha. Ukongeza, i-fatty amine polyglycerol ether ineempawu ezithile zokuthambisa kunye ne-antistatic, ngoko ke xa isetyenziswa ekuhlambeni amalaphu, inokusombulula isiphene sokuziva kwesandla esibi emva kokuhlamba.
1. Isetyenziswa njengeemulsifiers zezinambuzane
Ukongeza ekubeni nefuthe elihle lokuxubha ii-surfactants ezingezizo i-ionic, ii-surfactants ze-fatty amine polyglycerol ether nazo zinefuthe elithile lokubulala iintsholongwane kunye nokubulala iintsholongwane kwii-surfactants ze-cationic, nto leyo ezenza zibe yi-surfactant exutyiweyo "enefuthe elininzi": azinakunyusa kuphela ukudumba kwazo kodwa zikwaphucula ukunyibilika kwazo kumaqondo obushushu aphantsi, ngaloo ndlela ziphucula kakhulu ukuguquguquka kwazo kumaqondo obushushu njenge-microemulsions yezinambuzane. Le surfactant exutyiweyo, i-fatty amine polyglycerol ether, isebenza kakuhle kakhulu ekwenzeni ii-microemulsions ze-O/W, nto leyo enokunciphisa umthamo wee-surfactants kwaye inciphise iindleko.
1. Ukulungiswa kwee-antistatic agents
I-fatty amine polyglycerol ether surfactant inokwenza ifilimu yamanzi eqhubekayo kumphezulu wefayibha ngokusebenzisa iibhondi zehydrogen phakathi kwamaqela e-hydrophilic, amaqela e-hydroxyl kunye neemolekyuli zamanzi, ngaloo ndlela inefuthe elihle lokufunxa umswakama kunye nefuthe lokuqhuba. Inganciphisa ukungqubana kwefayibha kunye nokuveliswa kwe-electrostatic ngokwenza ifilimu yeoyile ye-hydrophobic kumphezulu wefayibha, kwaye inokubonisa nefuthe elithambileyo neligudileyo. Ukongeza, inxalenye ye-hydrophobic ye-fatty amine polyglycerol ether surfactant ifana neyama-fatty amine polyoxyethylene ether, kwaye inxalenye ye-hydrophilic inamandla ngakumbi kuneyokuqala kuba yongezwa ne-glycidol endaweni ye-ethylene oxide, ngoko ke ukufunxa kwayo umswakama kunye nefuthe lokuqhuba kunamandla kuneyama-surfactants e-polyoxyethylene ether ngokubanzi. Ngaphezu koko, ubuthi kunye nokucaphuka kwe-fatty amine polyglycerol ether surfactant kuphantsi kakhulu kuneyama-cationic surfactants, ngoko ke kulindeleke ukuba ibe yiarhente ebalaseleyo yokulwa ne-static.
1. Ukulungiswa kweemveliso zokhathalelo lomntu ezithambileyo
Kwinkqubo yokulungiselela ii-surfactants ze-fatty amine polyglycerol ether ezivela kwi-glycidol, ekubeni ulwakhiwo lwe-fatty amine polyglycerol ether luqulathe ii-ether bonds ezitshintshanayo kunye namaqela e-hydroxyl endaweni yokuba zilawulwe zii-ether bonds, ukwakheka kwe-dioxane kunokuthintelwa. Ukhuseleko lwayo luphezulu kunolo lwee-surfactants ze-polyoxyethylene ether. Ngaphezu koko, kukho inani elikhulu lamaqela e-hydroxyl kwi-fatty amine polyglycerol ether surfactants, eyonyusa i-hydrophilicity, inciphise ukucaphuka, kwaye ibenze babe buthathaka emzimbeni womntu. Ke ngoko, ii-surfactants ze-fatty amine polyglycerol ether zisetyenziselwa ukulungiselela iimveliso zokhathalelo lomntu oluthambileyo, ngakumbi ezo zeentsana nabantwana abancinci.
1.Isicelo kunyango lomphezulu we-pigment
Izifundo zifumanise ukuba ii-surfactants ezingezizo i-ionic zohlobo lwe-fatty amine zinokufumana iziphumo ezilungileyo kunyango lomphezulu wee-pigment eziluhlaza ze-phthalocyanine. Isizathu sale mpembelelo ilungileyo kukuba ezi surfactants zinokufunxwa kumphezulu we-pigment eluhlaza ye-phthalocyanine ngokwenziwa kweebhondi ze-hydrogen phakathi kwe--H kwi--OH kunye ne--NH kunye ne-nitrogen kumphezulu we-pigment eluhlaza ye-phthalocyanine. Zenza ifilimu yokugquma efunxwayo ngee-chain zazo ze-hydrocarbon eziphilic, kwaye ifilimu yokugquma eyenziweyo inokuthintela ngempumelelo ukuhlanganiswa kwee-pigment particles ngexesha lenkqubo yokomisa, ngaloo ndlela ithintela ukukhula okuqhubekayo kwee-crystal grains kunye nokufumana ii-pigment particles ezineekristale ezintle. Kwi-organic media, ii-pigment eziphathweyo zinokufunxwa ngokukhawuleza ukuze zenze ifilimu enyibilikisiweyo ngenxa yokuhambelana okuhle phakathi kwee-hydrocarbon chain kunye ne-organic media, okwenza ii-pigment particles zibe lula ukuzisasaza. Kwangaxeshanye, inokuthintela ukungqubana xa ii-pigment particles zisondelana. Esi siphumo siyanda njengoko ubude be-hydrocarbon chain bukhula kwaye ifilimu enyibilikisiweyo ikhula, nto leyo eluncedo ekuphuculeni nasekusasazweni okuncinci kwee-pigment particles. Amaqela abo athanda amanzi enza ifilimu emanzi ngokusebenzisa amanzi, nto leyo enokuthintela ngempumelelo ukutyibilika phakathi kwamasuntswana e-pigment kwaye yenze kube lula ukuwasasaza. Ii-surfactants ze-ether ezinamafutha zinamandla okuthanda amanzi kwaye zinokwenza ifilimu ethanda amanzi amaninzi. Ke ngoko, ii-pigments eziphathwe nge-surfactants ze-ether ezinamafutha zisasazeka lula emanzini, kunye namasuntswana amancinci, nto leyo ebonisa ukuba zinethuba elihle lokusetyenziswa kunyango lomphezulu we-pthalocyanine green pigments.
