Iimveliso
Twain 85
Iipropati zeMichiza
Le mveliso i-amber oily viscous liquid kunye noxinano lwe-1.00 ~ 1.05, i-viscosity ye-0.20 ~ 0.40Pa · s (25℃), i-flash point ye-321℃, kunye nexabiso le-HLB le-11.0.Ichithwa kwi-rapeseed oil, i-lysofibroin, i-methanol, i-ethanol kunye nezinye i-alcohol ephantsi kwekhabhoni, i-solvent enuka kamnandi, i-ethyl acetate, i-oyile ye-mineral, i-petroleum ether, i-acetone, i-dioxane, i-carbon tetrachloride, i-ethylene glycol, i-propylene glycol, njl. .
Sebenzisa
Le mveliso isetyenziswa ngokubanzi ekusetyenzisweni kweoli kunye nokuthutha, amayeza, izithambiso, i-pigments yepeyinti, iingubo, ukutya, i-pesticides, imveliso ye-detergent kunye ne-metal surface corrosion inhibitor kunye nemveliso ye-agent yokucoca, njenge-emulsifier, i-softener, i-agent yokugqiba, i-viscosity reducer, njl. njenge-emulsifier, i-stabilizer, i-arhente yokumanzisa, i-diffuser, i-penetrant njalo njalo

Isalathiso sobugcisa
Ngokuhambelana ne-GB25554-2010 umgangatho wexabiso le-asidi yento esemgangathweni (KOH)/(mg/g) ≤2.0 ixabiso le-saponification (KOH)/(mg/g) 45-55 ixabiso le-hydroxyl (KOH)/(mg/g) 6chemicalbook5-80 ukufuma, w/%≤3.0 intsalela evuthayo, w/%≤0.25 Arsenic (As)/(mg/kg) ≤3 ilothe (Pb)/(mg/kg) ≤ 2-oxyethylene (C2H4O), w/%65.0 ~ 69.5
Indlela yokuvelisa
I-1mol Span-80 yayishushu kwaye yafakwa kwi-kettle yokusabela, yongeza i-catalyzed sodium hydroxide isisombululo se-aqueous phantsi kokuvuselela, ukuvuselela, ukucoca kunye nokuphelelwa amandla kwamanzi.Emva kokutshintsha umoya kwiketile ngenitrogen, i-22mol ethylene oxide yaqala ukuhamba xa iqondo lobushushu lenyuka laya kutsho kwi-140℃, kwaye ubushushu obungasemva beChemicalbook bugcinwe kwi-180 ~ 190℃.Emva kokuba i-ethylene oxide igqithisiwe, i-vacuum iye yamiswa.Emva kokupholisa, i-liquid ye-material iqhutyelwa kwi-kettle ye-neutralization kwaye ingathathi hlangothi nge-acetic acid de ixabiso le-asidi limalunga ne-2, kwaye liguqulwe ngexabiso elifanelekileyo le-hydrogen peroxide.Ekugqibeleni, izinto eziphathekayo ziphelelwe ngamanzi kuze kube yilapho umthamo wamanzi u-3%, kwaye umkhiqizo ogqityiweyo unokufumaneka ngokupakisha ukupholisa ukukhutshwa.
