Imikhiqizo
Isiqephu 85
Chemical Properties
Lo mkhiqizo uwuketshezi lwe-amber oily viscous olunokuminyana okuhlobene okungu-1.00 ~ 1.05, i-viscosity engu-0.20 ~ 0.40Pa·s (25℃), iphoyinti elikhanyayo elingu-321℃, kanye nenani le-HLB elingu-11.0.Incibilika kuwoyela we-rapeseed, i-lysofibroin, i-methanol, i-ethanol namanye ama-alcohol aphansi ekhabhoni, i-aromatic solvent, i-ethyl acetate, iningi lamafutha amaminerali, i-petroleum ether, i-acetone, i-dioxane, i-carbon tetrachloride, i-ethylene glycol, i-propylene glycol, njll., ihlakazeke emanzini, njll. .
Sebenzisa
Lo mkhiqizo usetshenziswa kakhulu ekuxhashazweni kukawoyela nokuthuthwa, imithi, izimonyo, izibala zikapende, izindwangu, ukudla, izibulala-zinambuzane, ukukhiqizwa kwezihlanzi kanye ne-metal surface corrosion inhibitor kanye nokukhiqizwa kwe-ejenti yokuhlanza, njenge-emulsifier, isithambile, i-ejenti yokuqedela, i-viscosity reducer, njll. njenge-emulsifier, i-stabilizer, i-ejenti yokumanzisa, i-diffuser, i-penetrant nokunye

Inkomba yobuchwepheshe
Ngokuhambisana ne-GB25554-2010 inkomba ye-asidi yento ejwayelekile (KOH)/(mg/g) ≤2.0 inani le-saponification (KOH)/(mg/g) 45-55 inani le-hydroxyl (KOH)/(mg/g) 6chemicalbook5-80 umswakama, w/%≤3.0 insalela evuthayo, w/%≤0.25 Arsenic (As)/(mg/kg) ≤3 lead (Pb)/(mg/kg) ≤ 2-oxyethylene (C2H4O), w/%65.0 ~ 69.5
Indlela Yokukhiqiza
I-1mol Span-80 yashiswa ngaphambili futhi yafakwa kugedlela lokusabela, yengeza isixazululo se-catalyzed sodium hydroxide aqueous ngaphansi kokunyakazisa, ukugqugquzela, ukuhlanza kanye nokuphelelwa amandla kwamanzi.Ngemva kokufaka umoya eketelani nge-nitrogen, i-22mol ethylene oxide yaqala ukugeleza lapho izinga lokushisa lenyuka laya ku-140 ℃, futhi izinga lokushisa eliphambene le-Chemicalbook lagcinwa liku-180 ~ 190℃.Ngemva kokukhishwa kwe-ethylene oxide, i-vacuum yamiswa.Ngemva kokupholisa, uketshezi olubalulekile lushayelwa eketelani lokungathathi hlangothi bese luncishiswa nge-acetic kuze kube yilapho inani le-asidi selicishe libe ngu-2, bese likhishwa umbala ngenani elifanele le-hydrogen peroxide.Okokugcina, impahla iphelelwa amanzi kuze kube yilapho okuqukethwe kwamanzi kungu-3%, futhi umkhiqizo oqediwe ungatholakala ngokupholisa ukupakisha kokukhipha.
