What are the types of petroleum additives?

Petroleum additives are added to the base oil in a certain amount, for example, the anti-rust ability of mineral oil in the humidity tank is only about 4 hours, although the base oil and water are not mixed, but the addition of emulsifier to the oil can make the oil water into a stable emulsion, the additive is one of the important means to improve the quality of the oil and increase the variety of
oil.

Most of the petroleum additives are organic compounds, but there are also some inorganic products in aqueous liquid and emulsion products, and there is still a gap between the use, storage and performance requirements of the product, most of these properties can only be solved by petroleum additives, so petroleum additives occupy an important position in oil production and oil quality improvement, and have been trusted
by petroleum-related personnel in various countries.

Petroleum additives range is very wide, can be divided into: lubricating oil additives, fuel oil additives, composite additives and other product additives four categories, other additives include: paraffin additives, asphalt additives, waste oil and crude oil additives, but the main petroleum additives about 180 kinds, of which the main lubricating oil additives 10 kinds of about 120 kinds
.

The product symbol for petroleum additives consists of
three parts.

Part: The Hanyu Pinyin letter "t" is used to indicate the category
.

Two-part: Groups
are represented by a hundred or thousands of digits counting starting from the mantissa of Arabic numerals after t.

Three parts: the symbol is represented by 1 or 10 digits, counting
from the mantissa of the Arabic numerals after t.

1.
It should be proposed that the additive is not omnipotent, the additive is only one of the main factors to improve the quality of the oil, the contribution of the additive not only depends on its special composition, the base oil needs a certain refining depth or type, that is, solvent refining, hydrorefining, wax isomerization or synthetic oil, both of which are indispensable
.

2.
In addition to fuel or lubricant, detergent is a chemical substance that cleans engine parts and keeps engine parts clean, in the formulation of engine oil, cleaning agents are often used alkali metal soap to neutralize the acids produced by oxidation and combustion, for example, high-priced straight-chain alkylbenzene synthetic calcium sulfonate, long-chain alkylbenzene high-priced synthetic calcium sulfonate (TBN300), long-chain alkylbenzene high-priced synthetic calcium sulfonate TBN400), high-valence vulcanization
