Как glue paper or rubber to metal?

Stick paper, label, etc. in the usual way. on a smoothly polished metal surface, as you know, it is very difficult: the paper falls off very quickly. This inconvenience is easily eliminated using the following method: prepare a concentrated aqueous solution of soda, carefully moisten the metal surface with a heated solution; then wipe it dry with a rag, cover it with a thin layer of onion juice (cut the onion in half and rub this place) and paste paper on top, smeared with the following glue: take soft wheat flour, add the same amount of granulated sugar to it, pour this mixture over with cold water and mix until the density of sour cream, then brew with boiling water and stir until transparent. Paper pasted in this way is so strong that it can only be scraped off with a knife.

For gluing rubber to metal, the following glue is prepared: shellac is dissolved in ten times the amount of strong ammonia.

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 ... >>

Sand battery heating the city 10.03.2024

A pilot plant created by Polar Night Energy has already been in operation since 2022, but they are now planning to launch a commercial version of the “sand battery” in Finland for use during the cold polar nights.

Polar Night Energy's sand battery project represents a significant advance in energy supply, enabling the use of innovative technologies to efficiently heat cities in cold climates. Its environmental efficiency and long-term energy storage capabilities make it a promising solution to meet the energy challenges of the future.

As described by New Atlas, this innovative project consists of a huge steel bunker filled with sand or similar material, which is heated by a heat exchanger built into its heart. This makes it possible to use excess electricity from the grid, produced, for example, during periods of peak activity of renewable sources.

Such energy can be stored for months with minimal loss, ready to be used as needed. In Finland, the new sand battery will be tested in the district heating system of the municipality of Porninen, managed by the company Loviisan Lampo.

The sand battery is expected to measure 13 meters high and 15 meters wide and have a capacity of 1 MW with a capacity of up to 100 MWh. This, according to the company, will satisfy Porninen's weekly need for winter warmth or his monthly need in the hot summer. For comparison, the previous Polar Night sand battery model measures 4 by 7 meters, with a nominal power of 100 kW and a capacity of 8 MWh.

The new battery is expected to reduce carbon dioxide emissions from the district heating system by 160 tonnes per year, almost 70%. Sand for the project will also be sourced sustainably, namely ground soapstone, which is a byproduct of other local industries.

Completion of construction and testing of the new sand battery is expected in approximately 13 months.
