Ukubuyisela ioyile enzima kangaka, izisombululo zamanzi ze-surfactants ngamanye amaxesha zifakwa emngxunyeni ongaphantsi. Le nkqubo iguqula i-viscosity ephezulu...Funda ngokugqithisileyo -
Ubudlelwane phakathi koBume kunye nokuSasazeka kweeSurfactants
Iinkqubo zokusasazwa kwamanzi zezona zisetyenziswa kakhulu, kwaye zihlala zisetyenziselwa ukuhlalutya ubudlelwane phakathi kwesakhiwo se-surfactant kunye nokusasazeka. Njengee-particles eziqinileyo ze-hydrophobic, zinokufunxa amaqela e-hydrophobic e-surfactants. Kwimeko ye-anionic surfactants,...Funda ngokugqithisileyo -
Imisebenzi emihlanu emikhulu ye-Surfactants
1. Isiphumo Sokuxutywa Ubudlelwane obupheleleyo bamaqela athanda amanzi kunye nathanda i-lipophilic kwiimolekyuli ze-surfactant kwioyile okanye emanzini. Ngokusekelwe kumava, uluhlu lwexabiso le-Hydrophilic-Lipophilic Balance (HLB) le-surfactants lunqunyelwe kwi-0–40, ngelixa elo le-non-ionic surfactants liwela ngaphakathi kwe-0...Funda ngokugqithisileyo -
Unolwazi olungakanani malunga nemiphumo yokumanzisa kunye nokunyibilikisa kwezinto ezisetyenziswa kwi-surfactants
Isiphumo sokumanzisa, imfuneko: HLB: 7-9 Ukumanzisa kuchazwa njengesiganeko apho igesi efunxwe kumphezulu oqinileyo isuswa lulwelo. Izinto ezinokuphucula lo mthamo wokufuduka zibizwa ngokuba zii-agents zokumanzisa. Ukumanzisa ngokuqhelekileyo kwahlulwe ngeentlobo ezintathu: ukumanzisa...Funda ngokugqithisileyo -
