Khoom Taw Qhia
Polyoxyl 35 castor roj tseem hu ua PEG-35 Castor Roj, yog ib tug nonionic surfactant uas tshwm raws li daj ntseg daj, viscous kua nyob rau hauv chav tsev kub. Nws solidifies rau hauv ib qho muab tshuaj txhuam ntawm qhov kub thiab txias. Cov khoom no yog soluble hauv dej thiab soluble hauv cov rog, ntxhia roj, waxes, fatty acids, thiab ntau yam organic solvents. Nyob rau hauv ib tug 1% aqueous tov, nws pH ranges ntawm 6 mus rau 8. Nws yog resistant rau acids, dej nyuaj, thiab inorganic ntsev. Nws yog alkali-resistant ntawm qhov kub thiab txias, tab sis muaj zog alkalis tuaj yeem ua rau nws hydrolyze. Nws feem ntau yog siv los ua ib qho emulsifier hauv tshuaj tua kab thiab ua ib qho dispersant hauv luam ntawv pastes. Nws tseem tuaj yeem siv los tsim cov roj antistatic spinning roj rau acrylic thiab vinylon fibers. Polyoxyl castor roj yog tau los ntawm condensation ntawm castor roj nrog ethylene oxide.
