Applicable to Greases: The grease is a kind of solid or viscid lubricant which is made from lubrication oil added thickener and petroleum additives. The organic bentonite HT-A301 is a kind of popular thickening agent which is convenient and simple. The polar activator can be: Propylene carbonate, Ethanol/water(95/5), Acetone/water(95/5). Higher polarity, less amount.
Reference process:
1.Add half amount of base oil into the reactor,then heat up to 60-70 dgree celsius. 2.Add organic bentonite(10-15% of the total formulation) and mix 5-10 minutes. 3. Add polar activator(30-40% of bentonite amount) and other additives. Mix 25-30 minutes. 4.Add the balance base oil into the reactor and keep reavting 30 minutes. 5.Pump it and cross through three-roller mill or homogenizer. 6.Deaeration,filtration and package.
Remarkable: increase the dispersing speed and extend the dispersing time can improve the efficiency of HT-A301.
