Rubber varnishes are used not only to replace real varnishes, but mainly to obtain a water-permeable coating.

Lacquer for rubber galoshes

Rubber 70 g;
Purified pine resin 140 g;
Turpentine 250 g;
Bone black 20 g.

First, the rubber cut into pieces is dissolved by heating in turpentine, then resin is added and bone black (bone charcoal) is added to the still hot mass. The mixture is carefully ground, and to obtain complete uniformity, it can be passed through the rollers. Instead of pine resin, you can take the same amount of rosin.

Rubber varnish for leather

1 kg of rubber is dissolved in 8 kg of turpentine and 6 kg of oil copal varnish and 4 kg of boiled linseed oil are added.

Rubber varnish for glass

At 60 wt. hours of chloroform dissolve 1 wt. hours of rubber and 19 wt. hours of mastic. This varnish adheres perfectly to glass and can be painted in any color. With this varnish you can glue glass to glass, as well as attach metal or glass letters to glass. Chloroform can be replaced with other organic solvent.

Elastic rubber drying oil

1 kg of rosin is melted and heated until the mass begins to emit vapors. Then add with continuous stirring up to 500 g of well-ground rubber. 1 kg of linseed oil is added little by little to the obtained fairly uniform alloy and heated until the release of unpleasantly smelling vapors begins. Drying oil then continue to stir until it cools. This drying oil is not only completely waterproof, but also elastic. Fabrics and leather objects covered with this linseed oil do not form cracks or tears when bent.

Insulating varnish

Extinguish about 10 kg of well-burnt lime with 4 kg of water, add 5 kg of hot melted raw rubber, mix thoroughly and finally add with stirring to 10 kg of hot linseed oil drying oil. Stirring is continued until a homogeneous mass is obtained, which is filtered and left to cool. When used, the varnish is diluted with the required amount of drying oil and applied warm. It dries out in about 2 days.

This varnish is usually used for the walls of damp rooms as a means of protecting wood from house fungus, to make wood and fabrics waterproof, etc.

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 ... >>

New isolated 125W AC/DC converter with two outputs 24.06.2007

Mean Well has added two new models to its G3 series of AC/DC buck converters: RID-125-1205 and R1D-125-2405.

The new 125W models without forced cooling are the same as the previous models of the G3 series in terms of main characteristics. However, all electrolytic capacitors used in them can withstand temperatures up to 105°C.

In addition, the new modules withstand a short-term (5 sec) input voltage surge up to 300 V and vibration up to 5g, which allows them to be used in harsh environments. The voltage at the main output of the converter is switchable, 12 V or 24 V, and at the additional output - 5 V / 3 A to power the logic circuits.

The new converters are designed for use in industrial automation, test equipment, cash and bank terminals, printers and plotters. Isolation between outputs and protection against short circuits and overloads complete the features of the new converters.
