Gel is also known as jelly gum. The colloidal particles or polymers in the sol or solution are connected to each other under certain conditions to form a spatial network structure, and the structural voids are filled with the liquid as a dispersion medium (in the dry gel can also be a gas, the dry gel is also called aerogel), such a special dispersion system is called a gel. It has no fluidity and often contains a large amount of liquid inside.
For example, the water content of blood gel and agar can reach more than 99%. It can be divided into elastic gel and brittle gel. The volume of the elastomeric gel shrinks significantly when it loses its dispersion medium, and when it is reabsorbed into the dispersion medium, it expands again, e.g. gelatin.
When the brittle gel loses or reabsorbs the dispersion medium, the shape and volume do not change, such as silica gel. The process of forming a gel from a solution or sol is known as gelling.
Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction and protect machinery and processed parts, mainly playing the role of lubrication, cooling, rust prevention, cleaning, sealing and buffering. The concept of lubricant additives is the addition of one or several compounds to a lubricant in order to give the lubricant some new properties or to improve some of the properties already in the lubricant. Additives are mainly divided into antioxidants, anti-wear agents, friction modifiers (also known as oily agents), extreme pressure additives, detergents, dispersants, foam inhibitors, anti-corrosion and rust inhibitors, flow point improvers, viscosity index enhancers and other types.
The additives sold in the market are generally a combination of the above single additives, the difference is that the composition of a single additive is different and the proportion of several single additives within the compound additive is different. Just like Wilf's energy-saving engine oil, a variety of imported additives are added to make the lubricating oil achieve the effect of environmental protection and energy saving.
Although both can be called liquids, the biggest difference is that one is liquid and the other is non-liquid.

Both water-soluble and oil-based lubricants are common lubricants. Their role is to reduce friction and wear while the machine is running. However, there is a big difference between them.
First of all, the basis of water-soluble lubricants is water, unlike oil-based lubricants, which are made from petroleum. This means that they are very different in terms of handling. Because water-soluble lubricants can be easily cleaned by water, they are more environmentally friendly than oil-based lubricants.
In addition to this, water-soluble lubricants also have a better cooling effect. Since their main ingredient is envy water, they dissipate heat more quickly when they are used inside the machine. This helps maintain the temperature of the machine and does not overheat the machine while it is running, compared to oil-based lubricants.
However, water-soluble lubricants may have certain disadvantages over oil-based lubricants in some aspects. The first is their cost. Since they require more processing and materials, the manufacturing process is more complex, resulting in their ** being also higher.
Secondly, they may also be slightly less lubricating than oil-based oils when the machine is running.
From this, it can be concluded that water-soluble lubricants and oil-based lubricants have their own advantages and disadvantages. If you're more concerned about environmental protection and cooling, then a water-soluble lubricant is the best choice.
If you're concerned about cost-effectiveness and lubrication performance, then an oil-based lubricant may be a better choice. When using lubricants, you should first understand your needs and then choose the most suitable lubricant. <>
It's organic, of course.
Do you also do **, is there? The situation on my side is similar, I think the main thing is that the manufacturer's advertising is not enough, ***, but others don't believe it, there is no brand power, you have gained so much reputation, but it is not known, I think it is not enough to rely on **publicity, to TV**, interviews, to do.

Fully synthetic motor oil is best. Good synthetic motor oil is as clear as tap water. Of course. Thicker than tap water.
The quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature AC3 (sub-eutectic steel) or AC1 (super-eutectic steel), kept warm for a period of time to make it fully or partially austenitized, and then cooled to below ms (or isothermal near ms) at a cooling rate greater than the critical cooling rate for martensite (or bainite) transformation. Solution treatment of materials such as aluminum alloys, copper alloys, titanium alloys, tempered glass, etc., or heat treatment processes with a rapid cooling process are usually referred to as quenching. >>>More
