Is there a regulation on the order in which additives are added?

The order in which additives are added has a considerable impact on the quality of oil, and in the long-term exchange of lubricating oil production technology, there are some regulations that have reached consensus in principle:

(1) If there is a requirement for antifoaming of the oil, the anti-foaming agent should be added first to make it fully diffuse, and then other additives
should be added.

(2) For oil products with anticoagulant requirements, after adding antifoaming agents, anticoagulants should be added first; For oils with tackiness requirements, tackifiers
can be added subsequently.

(3) Then add other functional additives
.

(4) For those who have solid additives, the dissolution temperature should be determined according to the dissolution status of the solid additives to make them dissolved
.

(5) For additives with reaction requirements, immediately add the additives to be reacted after the addition of the first few additives, so that other additives
are added after the reaction is fully completed.

(6) For additives that do not need to react, but are to react together, if two additives with acidic and alkaline properties cannot be added at the same time, one should be added to the oil for dispersion, and then the other
is added.
