The use of bitumen emulsion has several benefits compared to regular bitumen binding materials: the viscosity of bitumen emulsions at room temperature is several times less than that of straight bitumen, facilitating easy permeation even small pores of the treated surface; emulsion higher adhesion to various surfaces, making it possible to create stronger road layers;Read More
Oil-based road construction bitumen is the main binding substance used in construction and repair of roads; it is elastic, can withstand low temperatures and temperature deviations without breaking, and resists deformations. However, specific operation of high load objects such as bridges, overpasses etc require higher quality of asphalt pavements. Normal bitumen cannot entirely meet theseRead More
Biodiesel is currently a vague term. Originally, it referred to the blend of 70-95% regular fuel an 30-5% vegetable oil. Now the term biodiesel refers to a fuel made from animal fat or vegetable oil by transesterification. Using biodiesel as marine fuel reduces the emission of practically all harmful substances usual for regular fuels. DueRead More
In reality, diesel fuel almost always contains water and other impurities. Since regular filters cannot capture water, and separator filters don’t always work as advertised, water contamination remains the biggest concern. The lifetime of a fuel system in a vehicle depends on the quality of the diesel fuel (mostly its purity). When the tank isRead More
Generation of electricity from the power of the wind is one of the most rapidly growing industries. In 2012 the total generation capacity of all wind farms amounted to 282 gigawatts. By 2017 this amount almost doubled and reached 539 gigawatts. The growing number and power of wind turbines requires increased maintenance and servicing. TheRead More
Oil purifier machines are used in just about all industries, because of the variety of oil-filled equipment. The energy sector uses oil to insulate and cool power transformer, machine building uses oil to protect friction parts of machines, for cooling and protection against corrosion. Not a single vehicle with an internal combustion engine can moveRead More
Transformer Oil Change is most often warranted by the results of sample analysis. There are certain parameters that indicate that the oil is in very poor condition and further use may cause transformer failure. These are oil acid number, dielectric strength and dissipation factor. Acid number shows the amount of acids in the transformer oil.Read More
The need for transformer oil conditioning arises when the oil is prepared for transformer filling, or when the oil already in the transformer deteriorates (acidity, dissipation factor, dielectric strength etc). Parameters of fresh transformer oil must meet certain requirements. However, the insulation fluid often becomes contaminated with dust, water and gas during transportation. Sunlight andRead More
Usual guaranteed transformer oil lifetime is 6-8 years. In most cases, the service life before reclamation of changing the oil is over 10 years. Careful operation extends the lifetime of the oil to 20-25 years, and even 30 years for well purified oil in transformers with regular expansion tanks. Incorrect use may reduce the serviceRead More
Electrical insulating oils belong to energy oils class. It also includes turbine and compressor oils. Despite the name, electrical insulating oils not only prevent possible contact between energized components of transformers, they also dissipate heat and extinguish arc in electrical switches. The better the performance of an insulating oil, the more reliable the equipment andRead More
The quality of transformer oil during transformer operation can be determined by taking and analyzing samples and comparing certain parameters against the standards. These parameters include acid number, dielectric strength, dissipation factor, settling point, flashpoint etc. In this article we will look at transformer oil acid neutralization. What is the acid number? Let usRead More
FR3 is a fireproof dielectric liquid based on ester. This product was specifically developed for use in transformer with high environmental and fire safety requirements. The base of the FR3 production are vegetable oils with natural additives. The fluid is fireproof, since it contains no petrochemicals, silicone organic compounds or any other potentially hazardous substances.Read More
In the process of emulsification, bitumen is dispersed into microscopic particles, while internal cohesion and viscosity of bitumen, as well as interfacial tension resist the formation of new phase boundary surface. Bitumen particles tend to coalesce. To make a stable emulsion, it is necessary not only to apply mechanical forces correctly to make small enoughRead More
Bitumen emulsions dispersed systems which consists mainly of bitumen and water, in which one liquid is dispersed in the other in the form of small droplets. The breaking (dispersion) of bitumen in water is usually done in colloid mills, also referred to as homogenizers or dispersers. Regardless of the actual design of the equipment, theRead More
Although the cost structure of vehicle fleets and central heating facilities is quite diverse, some expenses are common to all, especially the cost of fuel, which amounts to at least 40% of the total costs. Apparently, with the current economic trends, this number is about to keep growing in the coming years. Fuel homogenization increasesRead More
Bitumen emulsions have found wide use recently in construction and road repairs. Straight bitumen has long been the only binding material, but with the emergence of bitumen emulsion, the situation started to change, because emulsion have several apparent benefits compared to the traditional binding material, including: savings on heating; no harmful emissions into the environment;Read More
Bitumen emulsions are successfully applied in construction of pavements with various mineral aggregates by mixing on the road and impregnation surface treatment (single or double) and also by making black top with mineral aggregate made by mixing the aggregate with emulsions. Acidic bitumen emulsions ensure excellent adhesion of bitumen with the minerals for water resistantRead More
Most modern transformers use oil for insulation and cooling. The condition of oil defines transformer reliability and continuous power supply to the clients. Therefore, all procedures related to insulating fluid must be performed in strict accordance with the standards for quality and safety. In this article we will look at the process of transformer oilRead More
X-ray machines are used for medical or industrial purposes. The former are used for diagnosis of illnesses, while the latter help find defects in metal and non-metal structures (non-destructive control). Normal operation of an X-ray tube (XRT) requires high voltage, which may, depending on the purpose of the X-ray machine, reach as high as tensRead More
Industrial oil purification is a process that can recover used oil to newlike condition. If you are going to restore the oil, you need to know some important facts about oil purification equipment. Oil Purification Equipment Differences There are different types of oil purification equipment. Their differences are basically determined by the types of processedRead More
