process bleaching beeswax with light most common in the south. Produce such bleaching as follows. Light bleaching of wax The wax is melted and poured in a thin stream into water in which a small amount of alum is dissolved. The chips obtained as a result of such an operation are exposed to bleaching in the sun, but since bleaching occurs only from the surface, it is necessary from time to time to melt the wax and expose it to the sun again.

The process of bleaching is greatly assisted by ozonation of the air due to the fact that bleaching is due to the combined action of light and air. Experiments have shown that bleaching occurs much faster near a pine forest than in cities where the air contains little ozone. Artificial ozonation can be achieved by sawing turpentine or electrically.

The whitening process under normal conditions usually lasts from 10 to 60 days, depending on the time of year and the type of wax. When bleaching, there is a loss of 1-2% of the initial weight of the wax (not counting mechanical losses during reheating, which reach up to 10 ° C). The melting point of the wax after bleaching rises slightly. It should be noted that the bleaching rate depends on many factors. To speed up the bleaching process, keep in mind the following:

Wet wax requires less bleaching time than perfectly dry wax.

The surrounding air should be as dry as possible.

The temperature should be as high as possible above 20-35 °C.

The addition of bleached wax to raw wax accelerates the bleaching of the latter.

Bleaching can be greatly accelerated if the wax is poured onto a sheet of tin or sheet steel in a layer of 3 mm.

Fast bleaching is achieved by using a Laval emulsifier. To do this, melt the wax in water at a temperature slightly above its melting point, use an emulsifier to obtain an emulsion and pour it into cold water containing a small amount of turpentine. The resulting porous solid mass can be bleached under favorable conditions in 3-4 days. Adding a third of the already bleached wax to the wax accelerates the bleaching process even more.

The bleached wax emulsion can be broken by heating, after which the wax is separated from the water. Since the emulsifier has a high productivity, this method is successfully used on a factory scale and can compete with chemical bleaching methods.

The advantage of natural bleaching over chemical bleaching is that the specific properties of the wax, mainly its aroma, are not lost during natural bleaching.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

watermelon snow 10.03.2020

Throughout Antarctica, the snow turned a rich red color. Why did this happen?

Throughout the coldest continent, completely covered with snow-white ice, the snow has become a rich red color. The snow looks like it's been stained with blood. This is a terrible sight, and such snow is usually called "watermelon".

However, this color of snow is not at all paranormal. Scientists say that the snow is made red by a special algae that has begun to bloom en masse in Antarctica.

This is Chlamydomonas nivalis. This is a very small algae that usually blooms in the warm season. The anomaly is that at the end of February there has not yet been such a massive bloom in Antarctica. But due to global warming, the climatic summer has now come a little ahead of time, which led to the fact that the algae became more active ahead of time.

It has become warmer than usual in Antarctica, which provoked a massive flowering of Chlamydomonas nivalis. In general, this is not bad. But scientists are still worried, as the red snow is melting faster. And the massive melting of snow and ice will lead to an increase in the volume of water in the world's oceans, which will lead to a chain reaction. And what this reaction will lead to is still unknown.
