Tosol A-40: specifications, manufacturer

During operation of the internal combustion engine allocates a tremendous amount not only of useful energy and heat. For this reason, the design of each motor is provided the cooling system. It allows you to maintain an optimal temperature range of the internal combustion engine. If you take into account most cars, they use a liquid cooling system. As the working fluid can be used antifreeze or antifreeze. In today's article we will discuss the last type of coolant and find out its composition, and characteristics.

Description

What is antifreeze? This domestic version of antifreeze. This fluid was developed specifically for automobiles. The first antifreeze appeared in the 71st year, and was commercially used for the “Penny”, and later on all other «Lada». Also this liquid was applied on Soviet trucks KAMAZ and MAZ. The main advantage of her before the ordinary water (which is universally used previously) was in a wide temperature range. This liquid boiled at a temperature of 105 degrees and above, it does not freeze at -40. These characteristics were sufficient to use antifreeze without draining all year round. But before they had daily to drain the water at night, so she ripped the pipes and radiator in the winter.

At the moment there are different manufacturers of antifreeze A-40. Produced this liquid in different packaging. It can be barrels with a capacity from 50 to 217 litres, as well as plastic cans of 20, 10 and 5 liters. Available products in small flasks from a volume of one or two liters. As for color, Gostowski Tosol A-40 painted only in blue color. If to speak about import of antifreeze, paint them in different colors.

Structure

What is this liquid? It is based on ethylene glycol (dihydric alcohol). Also has distilled water and a package of useful additives. The latter are a group of chemical. This is the first generation of additives, which include nitrites, phosphates and silicates. They are added to protect the pipes and radiator from the corrosive effects of distilled water.

Specifications

One of the main characteristics – is the density of antifreeze A-40. Table that is in Guest, indicates the next parameter. For Tosol A-40 the value of the density is from 1.06 to 1.08 grams per cubic centimeter. If we consider antifreeze a-65, he's much higher this setting. It ranges from 1.08 to 1.11 grams per cubic centimeter.

An Important characteristic for any coolant – is the temperature of crystallization. For Tosol A-40 m, it is -40 degree Celsius. If to speak about the antifreeze of the brand 65, crystallization beginning temperature is -65 degrees Celsius. The following characteristics – the boiling point. Toolow for both brands it has to be not less than one hundred degrees Celsius. But as practice shows, this threshold modern coolant a lot more. On average, antifreeze boils at a temperature of 108-110 degrees.

Another property – corrosive to metals (it's cast iron, brass and copper). According to GOST antifreeze a-40 must match the parameter in 0.1 gram per square meter. This characteristic determines the level of metal protection of SOD against corrosion. This parameter is the same for antifreeze brands of 40 and 65.

The Following characteristics – the stability of the foam “With”. When diluted with a cold solution of zinc this option should be 5 units. And the volume of foam should not exceed 30 cubic centimeters. Rubber swell for antifreeze should not exceed five percent for the entire period of operation. This parameter affects the strength and elasticity of the pipes of the cooling system.

And finally, the last characteristic – the pH value. For liquids both brands it needs to be from 7.5 to 11 pH.

How does antifreeze cost?

On average, the cost of a five-liter cans of the coolant is 600 rubles. If we talk about the 10-litre flasks from, price is rarely more than one thousand rubles. What brand would not antifreeze, its price is always lower than that of antifreeze. This is easily explained by its operating characteristics.

Why is the antifreeze A-40 cheaper? The life of him does not exceed 60 thousand kilometers or two years (whichever comes first). For comparison, the red antifreeze is 150 thousand or five years. Also, the domestic liquid lower the threshold of boiling. Because of this, antifreeze is not recommended for use in high-temperature engines of modern cars. For their motors only suitable antifreeze, which boils at +120 and above.

Note: as a part of domestic antifreeze has additives that protect against corrosion of brass, iron, steel and copper. However, this list is missing the aluminum. Such radiators are now used on all foreign cars. Therefore it is not always the antifreeze would work well on imported cars.

Manufacturers

Today it is possibleto mention a few popular brands of this coolant:

• “Alaska”.
• ‘Torso’.
• “Dzerzhinsky».

What better to choose? Let's consider each brand individually.

Antifreeze “Alaska” A-40

This product is manufactured by OOO «Tektron”. The manufacturer claims that produces the best antifreeze on the market. But the reviews prove otherwise. The antifreeze does not meet the specs. And if the crystallization temperature still meets the standard (-41 degrees Celsius), it boils this liquid is already at 100 degrees Celsius. In view of this, this liquid is dangerous to use even on Vases of 2000-ies. But for “Classics” he still amiss. Resilience foam and spanelement – 1.5 and 20, respectively. PH – 8.1 pH. The conclusion of experts such: fractional composition of the antifreeze of the brand is non-standard.

Torso

This product is Produced, OOO «Arnica”. The manufacturer claims that the antifreeze A-40 Tors may be used in engines, domestic and import cars and trucks. The liquid is a mixture of ethylene glycol with additive package that protects SOD from corrosion, freezing, foaming and boiling. The product is compatible with rubber hoses and other parts of the seal. Does not contain nitrite-nitrate additives.

During the tests the temperature of crystallization amounted to -40 degrees. While the share of the distilled liquid at +148 amounted to 48 percent. Antifreeze boils at +105 degrees. Experts say that the brand is fully consistent with the specified technical regulations. However, reviews say that the use of such coolant on ODS imported engines still have to abstain.

Tosol A-40 &laquo «Dzerzhinsky»

This is a product from company “Novachem”. Is a high quality coolant based on ethylene glycol. The crystallization temperature is -40 degrees. PH – pH 8,10. What is the density of antifreeze A-40? Table in the Guest shows the figure of 1,085 grams per cubic centimeter. On the fractional composition antifreeze “Dzerzhinsky» also showed good performance. Boiling point is 105 degrees Celsius. While the share of the distilled liquid at 150 degrees – 45 percent. As studies have shown, Tosol A-40 &laquo «Dzerzhinsky» has the best performance characteristics among all of the above. But the cost of this product is much higher.

By the Way, recently the company released one product – antifreeze "Seabury”. It is used in ODS diesel and gasoline engines. Can be used at temperatures from -40 to +115 degrees Celsius. The composition includes demineralized water, dye, and additive package and ethylene glycol.
