With rusty bolts or nuts thatsometimes it's just impossible to unscrew, without breaking it, surely there were all motorists who prefer to carry out repairs and maintenance of their cars on their own. And if earlier craftsmen used folk remedies, moistening them with brake fluid, kerosene or turpentine to solve this problem, now they have come to the aid of a penetrating lubricant.
First appeared on the market, this tool is veryquickly gained recognition, not only among motorists, but also simply in everyday life. Why this happened is due to several reasons, above all, of course, convenience of use. After all, the penetrating lubricant itself is placed in a spray can, and it is convenient to use it, treating the desired part, while not smearing the hands. For hard-to-reach places, a tube is specially provided, which is put on the nozzle of the can. With its help, hidden elements of units and mechanisms, for example door locks, are processed.
Another reason is its multifunctionality: displacement of moisture, softening and removal of rust, creation of an anticorrosive protective film on the treated surface.
Perhaps the most famous representative of suchsprays is a universal lubricant penetrating the WD-40 or "Vedeshka", as it was nicknamed by the people. It was developed more than half a century ago in the US, but it continues to be at the peak of popularity, however, rather due to successful marketing, rather than its characteristics. So what is the legendary "Vedeshka"?
Officially the composition of the liquid manufacturercontinues to keep a secret, although in fact this mystery has long been uncovered: a mixture of white spirit (petroleum solvent) and paraffinic distillate. And from the moment of creation and up to this day, this lubricant has not undergone any changes, except for the addition of flavorings to it, and from time to time changing packaging.
For the sake of justice, it should be noted thatpenetrating lubricant "VD-40", first of all, is a water displacer, as evidenced by its name: WD - Water Displacement. But the manufacturer attributes to it still anticorrosive and protective properties. Nevertheless, there is no need to deceive ourselves on this score.
The main problem of "vedeshki"that the oil distillates that make up it really form a protective film on the surface to be treated, but it is so thin that it evaporates very quickly. In this regard, the protection against corrosion is short-lived, and the lubricating properties of the WD-40, which are positioned by the sellers as a penetrating lubricant, are virtually nonexistent.
In addition, practical experience of using"Vedeshki" 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 do not forget that while processing is in progress, the remains of the lubricant that was in it are washed out. Therefore, after using this liquid, the mechanism must be lubricated with oil.
But, one way or another, the "vedeshka" is really goodpenetrates even into complex mechanisms, while freeing up the rusted parts. In addition, the WD-40 perfectly cleanses a wide variety of dirt, including black marks from shoes and a hard-to-remove marker, as well as grease, glue residues and bituminous stains.
Of course, Vedeshka, despite its shortcomings, is able to help out in a difficult situation, but this is not the only penetrating lubricant offered on the market.
"Unisma-1" is a product developed bydomestic chemists back in the Soviet period as opposed to WD-40. And on some properties, it not only is not inferior to the famous competitor, but also surpasses it. However, the disadvantages inherent in American lubrication, inherited and Unisma-1. Therefore, both liquids can hardly be called multifunctional, and their application basically reduces to facilitating the dismantling of parts damaged by rust.
But Molykote Multigliss is a universal lubricantpenetrating, we can say, fully corresponds to this definition. In it, the manufacturer tried to get rid of the drawbacks inherent in the above lubricants.
In addition to high penetrating power and fastsoftening of rust, this liquid displaces moisture and at the same time does not allow it to be adsorbed on the surface. And due to the fact that inhibitors have been introduced into it, Molykote Multigliss continues to protect the part from corrosion after application.
Lubricating film formed on the surface, effectively reduces wear arising in the process of friction, while it is quite strong and retains the inherent properties for a long time.
Thus, the company to the manufacturer - Dow Corning, really managed to create a multifunctional product.
Another tool that is also considered quite effective, and, importantly, relatively inexpensive, is called UNI-M Spray from EFELE.
The peculiarity of this product is thatpenetrating the assembly, it does not flow out from there, forming not just a film, but a whole lubricating layer, capable of carrying various loads and preventing corrosion.
Strengthening of anti-wear properties UNI-M Spray provides the addition of antifriction fillers in its composition. And inhibitors protect against rust.
It is difficult to give an unambiguous answer to this question.In addition, the above penetrating fluids are just a small example of what you can buy today in a store. In fact, their choice is huge. One thing is clear: there are substitutes for such popular WD-40, working much better than this fluid.
After all, if you only want to unscrewa rusty bolt, you can do without special mixtures, and try it with the help of folk remedies: acetic essence or Coca-Cola, which contains orthophosphoric acid. And one and the other perfectly cope with corrosion. By the way, it is orthophosphoric acid that manufacturers use in the manufacture of many rust converters, which are used to process car bodies.
In general, before going to the store for "liquidkey, "as the penetrating lubricants are called in the people, it is necessary to determine whether it really is necessary to carry out the work that is planned to be done or that you can do with what is at hand.
