What color is lithium grease and the difference between lubricating oil butter and lithium grease?

Available in blue, taupe, and dark yellow.

The characteristics of lithium-based grease are as follows:

1) Lithium-based grease, especially the grease thickened with lithium 12-hydroxystearate, has only two phase change temperatures, the first phase change temperature (i.e., from pseudo-gel state to gel state) is generally above 170, and the second phase change temperature (i.e., from gel state to sol state) is generally above 200, therefore, when a suitable mineral oil is selected, it can be used for a long time at 120 or short-term use to 150.

2) Lithium-based greases, especially those thickened with lithium 12-hydroxystearate, can be seen by electron microscopy that their soap fibers form double-stranded, tangled twisted bands, so they have good mechanical stability.

3) The adsorption heat of alkanes by lithium 12-hydroxystearate and lithium stearate was determined by gas chromatography, and it was found that the binding strength of lithium 12-hydroxystearate and lithium stearate to the liquid phase on the surface of soap fibers and the binding strength to the liquid in the crystal lattice were larger, so the lithium-based grease had good colloidal stability.

4) The solubility of alkali metal in water is small, so lithium-based grease has good water resistance and can be used in wet and water-contact mechanical parts.

It is generally yellow, but some greases add color to increase recognizability, which has no effect on the performance of the grease.

Lithium esters are generally dark, such as brown, black, and dark yellow.

Because lithium has a black tint, lithium esters may exhibit different colors depending on the base oil and additives.

1. The uses of the three are different:

1. The use of lubricating oil: mainly plays the functions of lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering.

2. The use of butter: used as a food condiment, mainly used as a condiment, rich in nutrition but high in fat, so do not overeat.

3. The use of lithium grease: it is used for bearing lubrication of aircraft, automobiles, tanks, machine tools and various mechanical equipment.

The two and three have different overviews:

1. Overview of lubricating oil: lubricating oil and grease are one of the lubricants. And the so-called lubricant, simply put, is between two relative movements.

It has the function of reducing friction caused by contact between two objects.

2. Overview of butter: Butter is a kind of solid grease processed from cow brother milk, which is the product of filtering out part of the water from the thick object on the upper layer after stirring fresh milk.

3. Overview of lithium grease: Lithium grease is made from natural fatty acids (stearic acid.

or 12-hydroxystearic acid) lithium soap, made by thickening medium-viscosity mineral lubricants or synthetic lubricants, while synthetic lithium-based greases are made from synthetic fatty acid lithium soaps, thickening medium-viscosity mineral lubricants.

Third, the characteristics of the three are different:

1. Characteristics of lubricating oil: the color of the oil can often reflect its degree of refinement and stability. For base oils.

Generally, the higher the degree of refining, the oxides and sulfides of its hydrocarbons.

The cleaner it is removed, the lighter the color. However, even if the refining conditions are the same, the color and transparency of base oils produced by different oil sources and base genres** may be different.

2. Characteristics of butter: butter is divided into food butter and lubricating butter, lubricating butter, also known as grease, is a kind of lubricating oil. Here is a focus on food butter:

In Mongolian, it is called "Xiri Taosu", its taste is unique and pure, rich in nutrients, and it is a good product for herdsmen to entertain guests. Butter can be extracted from milk skins, white oil, or from the oily skins curdled from fresh milk.

3. Characteristics of lithium-based grease: lithium-based grease, especially the lubricating grease thickened with lithium soap of 12-hydroxystearate, becomes a multi-effect long-life general grease after adding antioxidants, antirust agents and extreme pressure agents, which can replace calcium-based anti-lubrication grease and sodium-based grease.

No. 3 is resistant to high temperatures. Because the No. 3 universal lithium grease dropping point is 193, the working taper is 240.

General purpose lithium grease is classified as 1 according to the consistency grade. It has good water resistance, mechanical stability, corrosion resistance and oxidation stability, and is suitable for the lubrication of rolling bearings and sliding bearings and other friction parts of various mechanical equipment within the working temperature of -20 120.

However, lithium grease does not belong to high-temperature grease, and the commonly used high-temperature grease models are: TKM1011 and NB 52 from Kluber, special high-temperature grease and high-temperature all-purpose grease from Hotolube, 2020 and 2025 from Great Wall, and KW220 from Jetlube.

According to the NLGI classification, the degree of penetration (needle penetration), grease ranges from 000 to 6, the higher the number, the harder the grease. 2 is commonly used lubrication, 3 is used for the lubrication of heavy load or vertical motor bearings.

Difference: Lubricating oil is generally a liquid, which is used for lubrication and cooling. It is light blue before it is worn, and it turns black after wear, that is, after use.

Butter is a solid and is mainly used for metal surface lubrication and waterproof and corrosion protection. It used to be yellow, but it turns black after use!

Lithium grease is gelatinous. It is a high-temperature oil with good water resistance, and can be easily used in wet and water-contact mechanical parts.

Lubricating oil is a liquid or semi-solid lubricant used in various types of automobiles and mechanical equipment to reduce friction and protect machinery and processed parts, mainly playing the functions of lubrication, cooling, rust prevention, cleaning, sealing and buffering.

Butter is a colloquial name for calcium-based greases. The origin of the common name is probably the earliest type of grease is calcium-based grease, which has a yellow appearance, like lard, and people vividly call it butter. Nowadays, grease has developed a variety of lubricating products.

In addition to calcium-based greases, lithium-based greases, complex lithium-based greases, and bearing greases and gear greases have been used in a variety of colors.

Lithium-based grease is made of hydroxyl fatty acids, lithium soap, thickened mineral oil, and added anti-oxidation, anti-rust, anti-corrosion and other extreme pressure anti-wear additives. Lithium-based grease has excellent water resistance, mechanical stability, extreme pressure and wear resistance, water resistance and pumpability, rust resistance and oxidation stability. Lithium-based greases also provide excellent lubrication performance under extremely harsh operating conditions.

(1) Grease, commonly known as butter, grease (butter) is a classification of lubricating oil, and lithium-based grease is a type of grease (butter).

2) Lithium grease is divided into fully synthetic base oil lithium grease and mineral base oil lithium grease according to the base oil, and the quality is far better than that of ordinary lithium grease.

The main use is different, the lubricating oil is generally liquid, the butter used for lubrication and cooling is solid, mainly used for metal surface lubrication and waterproof and anti-corrosion, lithium grease belongs to high-temperature oil.

The difference between the two is: lithium-based grease is gelatinous, belongs to high temperature resistance, has good water resistance, and has filial piety to burn the stuffy parts of the machine that are conducive to moisture and contact with water. Butter, on the other hand, is solid and is mainly used for metal surface lubrication and waterproof and corrosion protection.

Calcium-based grease is commonly known as butter.

This colloquial name is derived from probably the earliest type of grease called calcium-based grease.

Its appearance is yellow, similar to lard, so people have given it a butter name.

Today's greases have evolved and a wide variety of new lubricants have been introduced.

For a long time, there are not only calcium-based greases, lithium-based greases, and complex lithium-based greases, but also lubricants classified by application, such as bearing grease, gear grease, and so on.

Lithium-based grease is made of hydroxyl fatty acids, lithium soap, thickened mineral oil, and blended with a variety of anti-oxidation, anti-rust, anti-corrosion and other anti-wear additives.

It has good water resistance, extreme pressure and wear resistance, water resistance, anti-rust and oxidation stability.

Lithium-based greases deliver their superior lubrication capabilities even under extremely harsh conditions.
