With rusted bolts or nuts thatsometimes it is simply impossible to unscrew without breaking at the same time, all motorists must have come across, who prefer to repair and maintain their cars on their own. And if earlier craftsmen used folk remedies to solve this problem, wetting them with brake fluid, kerosene or turpentine, now penetrating lubricant has come to their aid.
The reasons for the popularity of penetrating lubricants
Having first appeared on the market, this tool is veryquickly gained recognition, not only from motorists, but simply in everyday life. Why this happened is due to several reasons, first of all, of course, ease of use. After all, the penetrating lubricant itself is placed in the spray can, and it is convenient to use it, processing the desired part, without soiling hands. For hard-to-reach places, a special tube is provided, which is put on the spray nozzle. With its help, hidden elements of components and mechanisms, such as door locks, are processed.
Another reason is its versatility: forcing out moisture, softening and removing rust, creating an anticorrosive protective film on the surface to be treated.
Lubricant penetrating WD-40
Perhaps the most famous representative of suchSprays is a universal grease penetrating WD-40 or "wedoshka", as it was called by the people. It was developed more than half a century ago in the United States, but continues to be at the peak of popularity, albeit more likely due to successful marketing than its characteristics. So what is the legendary "vesdeshka"?
Composition WD-40
Officially, the composition of the liquid manufacturercontinues to keep a secret, although in fact this secret has long been revealed: a mixture of white spirit (petroleum solvent) and paraffin distillate. And from the moment of creation and up to today, this lubricant has not undergone almost any changes, except for the addition of flavors to its composition, and from time to time changing packaging.
For the sake of justice, it should be noted thatWD-40 penetrating grease is primarily a water displacer, as evidenced by its name: WD - Water Displacement. But the manufacturer attributes to it also anti-corrosion and protective properties. Nevertheless, you should not flatter yourself on this score.
Disadvantages and advantages of "vesshki"
The main problem of "vedeshki" isthat the oil distillates in its composition do form a protective film on the treated surface, but it is so thin that it evaporates very quickly. In this regard, corrosion protection is obtained short-term, and the lubricating properties of the WD-40, which is positioned by the sellers, as a penetrating lubricant, are virtually absent.
In addition, practical experience of using“Waddies” revealed another unpleasant moment: after removing moisture, it contributes to its rapid adsorption from the surrounding air, which again leads to the formation and development of corrosion. And also you should not forget that while the treatment is going on, the remnants of the grease that was in it were washed out. Therefore, after using this fluid, the mechanism must be oiled.
Но, так или иначе, «вэдэшка» действительно хорошо penetrates even into complex mechanisms, while freeing the corroded parts. In addition, WD-40 perfectly cleans a wide variety of contaminants, including black traces from shoes and a hard-to-remove marker, as well as grease, glue residue and bituminous spots.
Possible alternative to WD-40
Of course, "vedeshka", despite its shortcomings, can help out in a difficult situation, but it is not the only penetrating lubricant offered on the market.
"Unisma-1" - a product developeddomestic chemists in the Soviet period, as opposed to WD-40. Moreover, in some properties it is not only not inferior to the famous competitor, but also surpasses it. However, the shortcomings inherent in American lubrication, inherited and "Unisma-1." Therefore, it is difficult to call both liquids multifunctional, and their use basically comes down to facilitating the dismantling of parts damaged by rust.
But Molykote Multigliss - universal greasepenetrating, we can say, fully meets this definition. In it, the manufacturer tried to get rid of the drawbacks of the above-described lubricants.
Помимо высокой проникающей способности и быстрого Rust softening, this liquid displaces moisture and at the same time does not allow it to adsorb on the surface. And due to the fact that inhibitors were added to its composition, Molykote Multigliss continues to protect the part from corrosion after application.
The lubricating film formed on the surface effectively reduces the wear that occurs during friction, while it is quite durable and retains the inherent properties for a long time.
Thus, the manufacturer's company, Dow Corning, really managed to create a multifunctional product.
Another tool, which is also considered to be quite effective, and, importantly, relatively inexpensive, is called UNI-M Spray from the company EFELE.
Особенностью этого продукта является то, что penetrating into the node, it does not flow out from there, forming not just a film, but a whole lubricating layer capable of withstanding various loads and preventing the formation of corrosion.
Strengthening the anti-wear properties of UNI-M Spray ensures that antifriction fillers are added to its composition. And inhibitors protect against rust.
What to choose?
Definitely an answer to this question is difficult.In addition, the penetrating fluids discussed above are just a small example of what can be bought in a store today. In fact, their choice is huge. One thing is clear that there are substitutes for such a popular WD-40, which work much better than this liquid.
In the end, if you want to unscrew onlyrust bolt, you can do without special mixtures, and try to do it with the help of folk remedies: acetic essence or coca-cola, which is composed of phosphoric acid. And one and the other copes with corrosion. By the way, it is the orthophosphoric acid manufacturers use in the manufacture of many rust converters, which are used to process car bodies.
In general, before you go to the store for "liquidthe key ”, as they are called penetrating lubricants in the people, should be determined whether it is really needed to do the work that is planned to be done or you can do with what you have at hand.
