As you know, wood glue cannot be stored in liquid form for the following reasons:

  1. its solutions gelatinize already at 6 °Be;
  2. they have a strong, extremely unpleasant odor and
  3. they get moldy very easily.

How to get liquid wood glue?

However, ordinary wood glue can very easily be turned into a liquid, free of all these disadvantages. To do this, 250 g of wood glue is dissolved in 1 liter of hot water, mixed with 10 g of barium peroxide, ground with 5 g of sulfuric acid, at 66 ° Be, and 15 g of water and heated for 48 hours in a water bath at a temperature of about 80 ° C. In this case, a noticeable amount of sulfur dioxide develops and the glue solution takes on a pleasant syrupy odor, loses its ability to gelatinize and, after condensing to half its original volume, does not mold even after prolonged exposure to air.

Such a solution has a slightly acidic reaction and glues very well. When dried, the peroxide-treated glue has the appearance of plates, very similar to gum arabic, and can successfully serve as a substitute for the latter, far exceeding its cheapness. With its adhesive power, the new product incomparably surpasses dextrin.

It should not be overlooked that when the glue is treated with barium peroxide and sulfuric acid, significant amounts of barium sulfate go into solution, just as a strong sugar solution also prevents the precipitation of barium by sulfuric acid.

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 ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

electric seaplane 13.12.2019

The Canadian company Harbor Air conducted the first flight of an electrified passenger seaplane DHC-2 Beaver.

On December 10, Canadian airline Harbor Air conducted a successful flight of an electric version of the DHC-2 Beaver seaplane on the Fraser River, near Vancouver.

The length of the DHC-2 Beaver is 9,2 meters and has a wingspan of 14,6 m. It can reach speeds of up to 255 kilometers per hour, and the range of the car is up to 732 kilometers. The device was converted into an electric aircraft by the Australian company MagniX, commissioned by Harbor Air: the car received a 200 kilowatt-hour battery and a Magni500 electric motor with a maximum power of 559 kilowatts, weighing 135 kilograms. A full charge of the battery electric DHC-2 Beaver, according to the developers, should be enough for 30 minutes of flight.

Further, after the first flight of the electric DHC-2 Beaver, the specialists will continue to test the machine - first, they will re-check all systems, and then proceed to further flight tests.
