Due to its properties and low price artificial and natural asphalt varnishes are widely used.

These varnishes are most used for metal products, as they protect them from rust. Varnishes for iron should be prepared from asphalt containing as little acid as possible. To give a more intense black color, oil-soluble blue paints are added to asphalt varnishes.

High quality asphalt varnish

Fuse 100 wt. parts of Syrian asphalt with 60 weight. hours of harpius, previously fused with 5-10% lime. Allow to cool and at a temperature of approximately 100 °C add 200 wt. including turpentine.

Cheap asphalt varnish

Alloy 5 wt. parts of Syrian asphalt with 40 weight. hours of coal tar pitch and, allowing it to cool to 80-100 °C, add 40 wt. including turpentine.

Stove varnish

100 wt. h. Syrian asphalt is fused with 80 wt. hours of drying oil and after cooling add 180 wt. h. turpentine.

Lacquer for iron

20 wt. parts of asphalt are fused with 15 wt. parts of condensed butter and at 180-200 °C add 2 wt. h. Then add 10 weight. parts of rosin and after cooling, dilute the weight. including turpentine.

Asphalt varnish for leather

10 wt. including natural asphalt, 10 wt. hours of coal asphalt and 10 wt. hours of pine resin melt with 2 wt. hours of wax and 2 wt. hours of paraffin, add to the mass of 40 wt. hours of linseed oil drying oil and 2 centuries. hours of dry Parisian blue, then heated with stirring until the liquid begins to give heavy vapors. As soon as a drop of the sample on the paper does not form spots, and upon cooling it stretches in thin threads, the mass is removed from the heat, allowed to cool slightly and 10 wt. hours of turpentine and 10 wt. including benzene.

The leather intended for lacquering is first dyed with a basic color solution of 10 wt. hours of methyl violet in 10 wt. hours of strong wine alcohol. After drying, varnish is applied, and the skin takes on a bluish-black appearance with a brilliant tint.

Insulating asphalt varnish

Condensed linseed oil 150 g;
Asphalt 50 g;
Sulfur 3,5 g;
Gleta 1 g;
Turpentine 50 g;
Gasoline 200 g;
Pyrolusite 0,5 g

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Cleaner in a freshly painted room 07.01.2013

At BAU 2013, German scientists from the Fraunhofer Institute will present a promising method for cleaning up the environment. The widespread use of new technology will make people's lives longer and healthier.

This is a technology for cleaning the air from nitrogen oxides and other substances harmful to health using photocatalytically active surfaces. Simply put, the Germans have developed a spray coating that can destroy toxins when exposed to light. Such paint can be used to cover the interior walls of apartments, the exterior walls of houses, lampposts, public transport, etc. This will radically improve the ecological situation, especially in large cities, where the concentration of particulate matter and other toxins, such as nitrogen oxides, is extremely high, which causes a wide variety of diseases, from pulmonary edema to damage to the central nervous system.

The paint, developed by German experts, contains widely available titanium dioxide. This substance, under the influence of light, acts as a catalyst that converts nitrogen oxides into nitrates. The new coating is currently being tested for effectiveness and durability. After 2 years, it will become known exactly how much nitrogen oxides the new coating can remove from the air and how effective it will be in cleaning the atmosphere in cities and along highways.

If the tests are successful, titanium dioxide coating will be used almost everywhere. First of all, scientists from the Fraunhofer Institute plan to use the new coating in "smart" buildings - comfortable, economical with clean air that is harmless to health.
