Kugwiritsa ntchito ma surfactants a fatty amine polyglycerol ether

Kapangidwe ka ether ya fatty amine polyglycerolchopangira madziakuwonetsedwa pachithunzi chili pansipa. Magulu ake okonda madzi amapangidwanso ndi magulu a hydroxyl ndi ma bond a ether. Komabe, kusinthana kwa magulu a hydroxyl ndi ma bond a ether kumasintha kapangidwe ka ether bond-dominated ka ma surfactants a polyoxyethylene ether-type nonionic. Pambuyo posungunuka m'madzi, kupatula kupanga ma bond ofooka a hydrogen pakati pa ma atomu a okosijeni pa ma bond a ether ndi ma atomu a hydrogen m'madzi ngati awa, amathanso kuyanjana ndi madzi kudzera m'magulu a hydroxyl. Chifukwa chake, ma surfactants a fatty amine polyglycerol ether amatha kusungunuka bwino m'madzi ndi nambala yaying'ono yowonjezera ya glycidol, zomwe zikutanthauza kuti ma surfactants a fatty amine polyglycerol ether ali ndi hydrophilicity yolimba kwambiri kuposa ma surfactants a polyoxyethylene ether. Kuphatikiza apo, ma surfactants a fatty amine polyglycerol ether ali ndi kapangidwe ka ma amine achilengedwe, zomwe zimawapatsa mawonekedwe ochepa a ma surfactants a nonionic ndi cationic. Pamene nambala yowonjezera ili yochepa, imasonyeza makhalidwe a ma surfactants a cationic, monga kukana asidi koma kukana kwa alkali kochepa komanso ntchito zina zowononga mabakiteriya. Pamene chiwerengero cha zowonjezera chikukwera, khalidwe lawo losakhala la ionic limawonjezeka; silidzagwera mu mayankho a alkaline ndipo ntchito yawo pamwamba imakhalabe yofanana. Pamene makhalidwe a nonionic akuwonjezeka ndipo makhalidwe a cationic akuchepa, kusagwirizana kwawo ndi ma surfactants a anionic kumachepa, zomwe zimathandiza kuti mitundu iwiriyi igwiritsidwe ntchito pamodzi.

Kwakutsuka zovala m'mafakitale

Mafuta a polyglycerol ether surfactants amakhala ndi makhalidwe osiyanasiyana kutengera manambala osiyanasiyana a adduct. Nambala yochepa ya adduct imapatsa surfactant mawonekedwe a cationic surfactants, imawonjezera kusungunuka kwake kutentha kochepa, komanso imapereka detergent yabwino kwambiri pa kutentha kwakukulu. Pamene chiwerengero cha adduct chikukwera, khalidwe la nonionic limawonjezeka, kotero surfactant sidzagwa mu alkaline solutions ndipo ntchito yake pamwamba imakhalabe yofanana. Pamene makhalidwe a nonionic akulimba ndipo makhalidwe a cationic akufooka, kusakaniza ndi anionic surfactants kungachepetse kwambiri kupsinjika kwa pamwamba ndikuwonjezera emulsifying ndi wetting performance. Mofanana ndi unyolo wa polyoxyethylene, hydrophilicity yake ndi steric inhibition effect zimatha kuletsa kwambiri mvula kapena kusonkhana kwa sopo. Kuphatikiza apo, fatty amine polyglycerol ether ili ndi makhalidwe ena ofewa komanso antistatic, omwe amatha kuthetsa vuto la kusamva bwino kwa manja mukatsuka zinthu za ulusi.

Yogwiritsidwa ntchito pamankhwala ophera tizilombo

Popeza ma surfactants a fatty amine polyglycerol ether ali ndi mphamvu yabwino kwambiri yopangira ma surfactants omwe si a ionic komanso mphamvu zina zophera mabakiteriya komanso zophera mabakiteriya a ma surfactants a cationic, amagwira ntchito ngati "multi-functional" mixed surfactant. Sangowonjezera kukhuthala kwa madzi komanso amawonjezera kusungunuka kutentha pang'ono, zomwe zimapangitsa kuti kutentha kwa ma microemulsions ophera tizilombo omwe amapangidwa nawo kusinthasintha. Surfactant yosakanikirana iyi imagwira ntchito bwino kwambiri popanga ma microemulsions a O/W, zomwe zimathandiza kuchepetsa mlingo wa surfactant ndikuchepetsa ndalama.

Kukonzekera kwaZinthu Zoletsa Kusakhazikika

Ma surfactants a fatty amine polyglycerol ether amatha kupanga filimu yamadzi yopitilira pamwamba pa ulusi kudzera mu ma bond a hydrogen pakati pa magulu okonda madzi, magulu a hydroxyl ndi mamolekyu amadzi, motero amapereka kuyamwa kwa chinyezi komanso kuyendetsa bwino magetsi. Pakadali pano, amatha kupanga filimu yamafuta okonda madzi pamalo a ulusi kuti achepetse kukangana kwa ulusi ndikuchepetsa kupanga magetsi osasinthasintha, komanso kupatsa kufewa ndi kusalala. Kuphatikiza apo, gawo la hydrophobic la ma surfactants a fatty amine polyglycerol ether limafanana ndi la ma ethers a fatty amine polyoxyethylene. Komabe, glycidol m'malo mwa ethylene oxide imawonjezeredwa ku gawo la hydrophilic, zomwe zimapangitsa kuti hydrophilicity ikhale yamphamvu. Chifukwa chake, kuyamwa kwawo chinyezi ndi magwiridwe antchito awo kumaposa ma surfactants a polyoxyethylene ether. Kuphatikiza apo, ma surfactants a fatty amine polyglycerol ether ndi ochepa poizoni komanso okwiyitsa kuposa ma surfactants a cationic, zomwe zimapangitsa kuti akhale odalirika ngati othandizira amphamvu kwambiri.

Kukonzekera kwaZogulitsa Zosamalira Munthu Wochepa

Pakupanga ma fatty amine polyglycerol ether surfactants pogwiritsa ntchito glycidol, kapangidwe ka mamolekyulu kamakhala ndi ma ether bond osinthika ndi magulu a hydroxyl m'malo mokhala ndi ma ether bond ambiri. Izi zimapewa kupangika kwa dioxane ndipo zimapangitsa kuti pakhale chitetezo chapamwamba poyerekeza ndi ma polyoxyethylene ether surfactants. Kuphatikiza apo, magulu ambiri a hydroxyl mu ma fatty amine polyglycerol ether surfactants amathandizira hydrophilicity ndikuchepetsa kukwiya, zomwe zimapangitsa kuti khungu la munthu likhale lofewa kwambiri. Chifukwa chake, ma fatty amine polyglycerol ether surfactants amagwiritsidwa ntchito popanga zinthu zosamalira thupi, makamaka zinthu zosamalira ana.

Kugwiritsa Ntchito Kusintha kwa Pigment

Xu Yanli'Kafukufuku wasonyeza kuti ma surfactants osakhala a ionic ochokera ku mafuta a amine amapeza zotsatira zabwino pochiza pamwamba pa utoto wobiriwira wa phthalocyanine. Kuchita bwino kumeneku kumachokera ku njira iyi: ma surfactants otere amatha kumizidwa pamalo a utoto kudzera mu mgwirizano wa hydrogen womwe umapangidwa pakati pa maatomu a hydrogen m'magulu a -OH ndi -NH ndi maatomu a nayitrogeni pamalo a utoto wobiriwira wa phthalocyanine. Maunyolo awo a lipophilic hydrocarbon amapanga filimu yophimba yomatira. Chophimba chopangidwacho chimaletsa kusonkhana kwa tinthu ta pigment panthawi youma ndikuletsa kukula kwa kristalo, ndikupanga tinthu ta pigment tomwe timakhala ta crystalline. Pamene utoto wokonzedwawo uyikidwa mu organic media, maunyolo a hydrocarbon amakhala ndi mgwirizano wabwino ndi organic media ndipo amasungunuka mwachangu kuti apange filimu yosungunula, zomwe zimathandiza kufalikira kwa utoto. Pakadali pano, filimuyo imalepheretsa kusuntha kwa utoto pamene tinthu ta pigment tiyandikirana. Izi zimakula ndi maunyolo ataliatali a hydrocarbon ndi mafilimu okhuthala osungunula, zomwe zimapangitsa kuti tinthu ta pigment tisinthe komanso kufalikira kwa tinthu tating'onoting'ono. Magulu a hydrophilic amasungunuka kuti apange mafilimu osungunula, omwe amaletsa kusuntha pakati pa tinthu ta pigment ndikuthandizira kufalikira. Ma fatty amine polyglycerol ether surfactants ali ndi hydrophilicity yabwino kwambiri ndipo amatha kupanga mafilimu okhuthala a hydration. Chifukwa chake, utoto wothiridwa ndi fatty amine polyglycerol ether surfactants umafalikira mosavuta m'madzi okhala ndi tinthu tating'onoting'ono, zomwe zikusonyeza kuti zitha kugwiritsidwa ntchito bwino pochiza pamwamba pa utoto wobiriwira wa phthalocyanine.
