Polyethylene terephthalate film grade PET-E is used at temperatures up to +155 °C. The film is produced with a thickness of 6; 8; 10; 12; 15; 20; 35; 50; 70; 100; 125; 175; 190 and 250 µm.

Electrical strength film at an alternating voltage with a frequency of 50 Hz should be at least: with a thickness of 6-25 microns - 180 kV / mm, 3 and 50 microns - 140 kV / mm, 70-125 microns - 100-120 kV / mm, 190 and 250 microns - 80-90 kV/mm. Shelf life 12 years.

Fluoroplast-4 is a polymerization product of tetrafluoroethylene. It is used for the manufacture of products and films that are resistant to strong aggressive media, as well as with high electrical properties at temperatures up to 260 °C.

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 ... >>

The psychological state of the soldier will show a special marker 23.10.2012

American military scientists from the Defense Science Board (DSB) announced that in the coming years, with the help of genomics and biomarkers, it will be possible to pinpoint the critical point, after which the soldier, as they say, "goes crazy" or simply becomes inadequate to act. So far, the only way to prevent such cases is preventive work, but it is still impossible to predict exactly when a person will reach a critical point.

Following the tragedy at Fort Hood, Texas, in which Major Nidal Hassan killed 13 people, in November 2009 the DSB established a task force to investigate the problem of predicting violent behavior. For the first time, ways were outlined for the implementation of this important task, although scientists emphasize that it is still far from reliable forecasting of an outbreak of aggression.

Scientists have created a so-called stress response curve, which shows the performance of a soldier under stress. The graph clearly shows that productivity rises with stress levels, but under pressure, people perform better only up to a certain point. Eventually, stress continues to rise and human productivity levels off. At a certain point, stress reaches a critical point, productivity rushes to zero, and a person suddenly becomes inadequate and, for example, begins to shoot into the crowd with a machine gun.

The report of scientists from the DSB notes that serious cases of inappropriate behavior could have been avoided if qualified data collection could be organized, and if others had at least some knowledge of the signs of a crisis.

According to scientists, there are two ways to solve the problem of inappropriate behavior under stress. First, it is necessary to increase the stress resistance of soldiers, that is, to push back the critical point and ensure efficiency and sanity under serious psychological and physical stress. Secondly, it is worth organizing the collection and analysis of data on human behavior, as well as creating and widely using special sensors that can determine biomarkers of physiological signs of stress. In this case, it will be possible to "pull" a person out of a dangerous situation before he commits an irreparable act.
