Line mixers-dispersers are used in industrial production of bitumen emulsions for waterproofing. What is a disperser? A disperser is a continuous colloid mill. In this mill, bitumen emulsion is prepared in a rotor-stator mixer with a gap 0.2-0.6 mm between the moving part and the housing. The rotor breaks and tears particles and droplets ofRead More
Most substances used in households and industry are dispersed systems (solid particles or droplets suspended throughout another substance) or solutions, where mixing takes place at the molecular level. Examples of suspensions are mortar mixture, paint, white glue or bitumen emulsion used for waterproofing works. What is bitumen emulsion? Bitumen is a hydrocarbon resin (derived fromRead More
To begin, let us recall what exactly is the essence of a process called “homogenization”. In short, it is the process of obtaining a homogeneous substance by stirring. If a solid or liquid substance is milled to powder or emulsion by mechanical decomposition, then it is dispersion (of liquids and other substances). To achieve thisRead More
Asphalt emulsions have been in existence for almost 100 years in the United States and the rest of the world. They were first developed in the early 1900s, used in road applications in the 1920s, with continued growth due to World War II and the energy crisis of the 1970s (1). Asphalt emulsions have foundRead More
The main objective of laying asphalt concrete mixtures as a road surface is to ensure its adhesion to the bottom layer. A practical solution to this problem is -using bitumen emulsions. Bitumen emulsion disperse system consists of: bitumen and water. Thus the smallest particles of bitumen are dispersed in water without being mixed with it.Read More
Colloid mill is a technical device used for high fineness grinding, dispersion, emulsification and preparation of homogeneous solutions. The cutting mechanism of colloid mills can consist of: single sickle knives; knives paired with a cutting unit with gratings, fingers, reflectors, disks etc.; combined cutting apparatus. Knives can be smooth or toothed. In most cases theyRead More
In April, representatives of our company visited Ghana to access the current state of a UVB-1 plant. This equipment was sold in 2012 and has since produced 40000 m3 of bitumen emulsion. This material is in demand in Ghana, as this country is badly in need of building new and repairing the existing automobile roads.Read More
There is a legend about the origin of mayonnaise. It says that this sauce was invented by a chef of the French garrison, which was locked by the British on the island of Menorca in the city Mahon (Mayon). The besieged experienced problems with food – there were only olive oil and turkey eggs, andRead More
The history of mustard extends back a couple of millennia. Today it is one of the most popular spices used in the cuisines of many nations. In general, mustard is a mixture of mustard seeds, water, vinegar and various additives. The taste of mustard depends on additives and plant seeds (white, black, brown (saperda/Indian) orRead More
The modern food industry produces a wide range of products made from fruits and berries such as preserves and jam, jelly and marmalade, and grated and crushed berries. At the heart of all this diversity are preservative properties of high concentrations of sugar. When the amount of sugar is between 60 to 65%, sugar syrupRead More
