Ii-surfactants ezine-foam ephantsi ziquka iikhompawundi ezininzi ezingezizo i-ionic kunye ne-amphoteric ezinezakhono zokusebenza ezibanzi kunye namathuba okusetyenziswa. Kubalulekile ukuqaphela ukuba ezi surfactants azizo ii-agents ezingena-foam. Kunoko, ukongeza kwezinye iipropati, zibonelela ngendlela yokulawula ubungakanani be-foam eveliswayo kwizicelo ezithile. Ii-surfactants ezine-foam ephantsi nazo zahlukile kwii-defoamers okanye ii-antifoamers, ezizizongezo ezenzelwe ngokukodwa ukunciphisa okanye ukuphelisa i-foam. Ii-surfactants zinikezela ngeminye imisebenzi emininzi ebalulekileyo kwimilo, kubandakanya ukucoca, ukumanzisa, ukuxuba, ukusasaza, nokunye.
Ii-Amphoteric Surfactants
Ii-surfactants ze-amphoteric ezineeprofayili ze-foam eziphantsi kakhulu zisetyenziswa njengee-surfactants ezinyibilikayo emanzini kwiifomyula ezininzi zokucoca. Ezi zithako zibonelela ngeempawu zokudibanisa, ukuzinza, ukucoca, kunye nokumanzisa. Ii-surfactants ezintsha ze-amphoteric ezinemisebenzi emininzi zibonisa iimpawu eziphantsi kakhulu ze-foam ngelixa zibonelela ngokusebenza kokucoca, iiprofayili ezibalaseleyo zokusingqongileyo nokhuseleko, kunye nokuhambelana nezinye ii-surfactants ezingezizo ze-ionic, ze-cationic, kunye neze-anionic.
Ii-Alkoxylates ezingezizo ii-ionic
Iialkoxylates ezine-foam ephantsi ezinomxholo we-ethylene oxide (EO) kunye ne-propylene oxide (PO) zinokubonelela ngokusebenza okuphezulu kokucoca kunye nokutshiza kwiindlela ezininzi zokucoca ezishushu kakhulu nezisebenzisa oomatshini. Imizekelo ibandakanya izixhobo zokuhlamba izitya ngokuzenzekelayo, izicoci zobisi nokutya, izicelo zokucubungula i-pulp kunye nephepha, iikhemikhali zelaphu, nokunye. Ukongeza, iialkoxylates ezisekwe kutywala zineempawu eziphantsi kakhulu zokukhupha igwebu kwaye zinokudityaniswa nezinye izinto ezine-foam ephantsi (umz., iipolymers ezinyibilikayo emanzini) ukwenza izicoci ezikhuselekileyo nezingabizi kakhulu.
IiCopolymers zeBhloko ze-EO/PO
Ii-EO/PO block copolymers zaziwa ngeempawu zazo ezintle zokumanzisa nokusasaza. Iindidi ze-low-foam kolu didi zinokusebenza njengeemulsifiers ezisebenzayo kwiindlela ezahlukeneyo zokucoca kwimizi-mveliso nakwiziko.
Ii-Amine Oxides ezineFoam ephantsi
Ii-amine oxides ezinemilinganiselo ephantsi kakhulu ye-foam nazo ziyaqatshelwa ngokusebenza kwazo kokucoca kwiisepha kunye nee-degreasers. Xa zidityaniswe nee-hydrogels ze-amphoteric ezine-foam ephantsi, ii-amine oxides zinokusebenza njengomqolo we-surfactant kwiifomyula ezininzi zokucoca umphezulu oqinileyo one-foam ephantsi kunye nokusetyenziswa kokucoca isinyithi.
Ii-Ethoxylates zoTywala eziLungileyo
Ii-ethoxylates ezithile ze-linear alcohol zibonisa amanqanaba aphakathi ukuya kwaphantsi e-foam kwaye zingasetyenziswa kwiindawo ezahlukeneyo zokucoca umphezulu oqinileyo. Ezi surfactants zibonelela ngeempawu ezintle zokucoca kunye nokumanzisa ngelixa zigcina iiprofayili ezilungileyo zokusingqongileyo, impilo, kunye nokhuseleko. Ngokukodwa, ii-ethoxylates ze-alcohol ze-HLB eziphantsi zikhupha i-foam ephantsi ukuya kophakathi kwaye zinokudityaniswa nee-methoxylates ze-HLB eziphantsi ukulawula i-foam kunye nokuphucula ukunyibilika kweoyile kwiifomyula ezininzi zokucoca kwimizi-mveliso.
Ii-Ethoxylates ze-Amine ezinamafutha
Ezinye ii-ethoxylates ze-fatty amine zineempawu eziphantsi zokukhupha amagwebu kwaye zingasetyenziswa kwizicelo zezolimo kunye nokucoca okujiyileyo okanye kwiifomyula ezisekwe kwi-wax ukubonelela ngeempawu zokuxuba, ukumanzisa, kunye nokusasaza.
