Here are the recipes opaque pyroxylin varnish.

1st recipe:

20 g of celluloid is dissolved in 100 g of ethyl acetate and diluted with 120 g of methyl alcohol. When poured onto a glass plate, a white layer is formed, similar to enamel. If this solution is diluted with 250 g of methyl alcohol, then a very fine-grained matte white layer is obtained.

2st recipe:

10 g of the so-called alcohol-soluble collodion cotton is dissolved in 100 g of methyl alcohol. With rapid evaporation, a snow-white mass remains. When dissolved in ethanol, a clear coat is obtained.

3st recipe:

100 g of 100% ether-alcohol collodion is diluted in XNUMX g of acetic ether, as a result of which a white matte layer is also obtained.

When working according to the second method, the drying temperature can reach from 40 to 50 °C; according to the first method, a white layer is obtained only at ordinary temperatures.

White coatings are also given by the following compositions: an ether-alcohol solution of collodion with acetone, an acetic-ether collodion with alcohol, or an alcoholic solution of collodion diluted with methyl alcohol. With the addition of colorants, opaque colored layers are obtained; they have greater hiding power and adhere strongly to the material they cover.

To keep the first coat of polish or varnish from being sucked up by the wood and to make the object smoother without re-sanding; wooden objects are pre-coated with a layer of pyroxylin solution, to which a little resin varnish can be added. Pyroxylin solutions have the property of not being absorbed into the wood and do not soften the wood fibers, while leaving the color of the wood unchanged and clean. After applying polish or varnish to the wood, you can again, in order to protect it, cover it with a pyroxylin solution.

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 versions of Wi-Fi for tablets 04.02.2012

Semiconductor and consumer electronics manufacturers are working to improve the connectivity and ability of tablets to stream content to TVs. Michael Halston, senior vice president of Broadcom Corporation, spoke about this at the DesignCon 2012 conference. Broadcom is developing a technology called 5G Wi-Fi based on the 802.11ac version of the Wi-Fi specification.

The technology is called 5G Wi-Fi because it represents the fifth generation of Wi-Fi for consumer devices, Halston said. Following Broadcom, other companies began to use this name. Wi-Fi names are confusing: for example, ordinary users do not know that the 802.11ac version of this standard is newer than 802.11n.

The next Wi-Fi innovation will be the emergence of the 802.11ad standard, which defines the operation of devices in the 60 GHz band and is characterized by very high transmission speeds, but a shorter range. According to Halston, 802.11ad can be considered a revolutionary standard in contrast to the "evolutionary" standard 802.11ac. Although some companies may release 802.11ad-enabled chips this year, the market is not yet ready for these new products. Full adoption of this standard will occur within the next five years.

Products with support for 802.11ac, or 5G Wi-Fi, which will find application in tablets, are expected by the middle of this year.
