Types of data cables for buildings

Types of data cables for buildings

Building services used many types of data cables. The main aim of these data cables is to make sure that the data is transmitted at incredibly fast speeds. The cables that are used in buildings must be handled with care and perfection. It will ensure that the installation is done perfectly and no error occurs. The dilemma of today is that there are many companies working in the field which provide services but not all are same. It also means that the company chosen to perform the task must be equipped with the knowledge. When it comes to data packet types there is a clear classification.

The capacity as well as traveling speed of all types of data slows when the signal runs on copper-based medium. Tremendously fast speeds can be achieved if fiber optic cables are installed. Most of the industries and offices which are built despite this fact always go for copper cables. The only reason behind this is the cost which becomes double if fiber optic installation is done.

There are some external factors are well which can reduce the data transfer rate. These factors are independent of the type of cable used. First of all is the fact that the cable is twisted. The data packets find it difficult to travel through the twisted region thereby increasing line losses. The second factor is that of joints. They work in the same way as twists do and therefore the data transfer rates are reduced. Substandard and misconfigured systems can also lead to issues which ultimately become a dilemma.  For cost reduction and overall efficiency achievement, it is advised to make sure that the all these factors are removed before proceeding with proper data transfer working.

Some of the main data cables used by data cabling services companies are as follows:

  • Twisted which is made up of copper
  • Fiber optic as the name depicts is made up of fiber
  • Coax, also known as coaxial cable is made up of copper

The twisted cables are further categorized into UTP and STP. The only difference is that a silver coating is present in STP and absent in UTP. The STP cables are used by most of the organization. They are higher in price as compared to UTP but still much cheaper as compared to fiber optic cables. Data transfer rate of up to 100 kHz can be obtained if this cable is used. A combination of UTP and STP for voice and data combined is also becoming common nowadays.

Fiber optic needs no intro. It is by far the best cable that has been developed. The data can transfer at the speed of light. It is therefore obvious that the transfer rates cannot be calculated at all. It is used by the very large corporation where data transfer speed matters. Copper based cables have several disadvantages which can easily be overcome when fiber optic is used.

Coax of Coaxial cable was once the top market cable but now it’s not the case. It is now mainly used for cable TV network. The usage of this cable in computer communications is close to zilch.

Do not hesitate and set your sight on choosing the most suitable for you and use Internet sources to the fullest.

Nanoscope is a new glance at nanoworld

Nanoscope is a new glance at nanoworld

You hardly imagine how the world could be tiny as well as giant at the same time. This opportunity is available for you with the recent nanotechnologies. On the scale of meters, our perception of life has some particular meaning and size and it is sort of impossible and impressive to penetrate and plunge in another dimension that is smaller than insect’s eye.

If you think that nanotechnology is modern concept, you a bit mistaken. It dates bake to the beginning of XX century when eminent Richard Feynman, who was American physicist, was credited with his raised interest in nanotechnology. However the heyday of nanoscience is estimated in the 1980s. Many books were published regarding this topic and they were really popular not only with scientists, but also among lay readers. Nowadays, new approaches are being developed by scientists, allow literally see the amazing molecular world, observe the complex organic molecules and the growth of crystals in atomic resolution, viruses and living tiny organisms.

Have you ever asked yourself, how small our world is at the nanoscale level? The thing is that the smallest bacterium has a length of about 200 nm, helically twisted double stranded DNA molecule is about two nanometers in diameter, and the distance between atoms in carbon materials is only 0.15 nm. It is obvious kind of hard to understand these dimensions because of its small quantity and our mistrust due to the fact that we could not see these viruses, cells and batteries. The importance of nanoscope should not be underestimated because it cares about our life, health and progress. In addition, modern science opens the possibilities of nano-tools in many technological spheres. Meanwhile, it has become increasingly important to challenge them in order to see whether the nanotools with high resolution as nanoscopes of LIG Tech could be useful. This idea was carefully checked by scientists, who have found two effective approaches that allow see materials at the atomic and molecular resolution. They are called scanning electron microscopy and atomic force microscopy. Continue reading “Nanoscope is a new glance at nanoworld” »

Mineral Binders Industrial Application & General Info

Mineral Binders Industrial Application & General Info

During the construction of buildings and facilities stone materials are used: bricks, stones, blocks, panels, facing tiles and many more. But to ensure the building is solid and warm these materials must be linked together into a single monolithic structure.

To do this binders are used. Binders also represent the main component of such artificial stone materials as concrete and mortar, in which they are fastened together with grain aggregates (sand, gravel and crushed stone).

One of the first bindings used by man was raw clay. In 3,000 BC people began to use more durable binders produced artificially by firing natural stone materials. The first material was probably a gypsum binder, the next one was air lime. However, due to the lack of water resistance such material didn’t fully meet the requirements of the construction. To improve the water resistance of binders volcanic ash was added to the air lime by the ancient Romans. Later, in the XVIII century, the builders discovered that by firing limestone with high content of clay a way more effective water-resistant binder can be obtained. So this is how hydraulic lime and roman cement were born. The impetus for the further development of the production and use of binders was the invention in the beginning of XIX century, a new quality of cement higher strength and water resistance, known as Portland cement.

Currently, a variety of other mineral binders which differ in their properties are used in the construction. The modern architectural companies, like a UK-based Telling, focusing on hydraulic lime and lime mortar technologies, use over 30 types of mineral binders depending on the purpose of the project and the environmental conditions.

Plasma Waste Recycling Radioactive Challenges

Plasma Waste Recycling Radioactive Challenges

Plasma waste processing is the newest method of disposal of solid waste, which essentially is a waste gasification. This method is the most promising among the recycling solutions, since such production does not set strict requirements to the feedstock, and yields a secondary energy in the form of hot steam or hot water to supply them to the final consumer, as well as a range of secondary products, such as granulated slag or ceramic tiles.

In fact, this is the best option for complex processing of garbage, fully environmentally friendly that produces heat and a variety of useful products from the most junky materials – household waste. With the emergence of such innovators as Simdean, the company famous for its industrial waste disposal, plasma waste disposal and research achievements, the method became more cost effective. However, it is still not a panacea. Continue reading “Plasma Waste Recycling Radioactive Challenges” »

The Basics Of Waterproofing

The Basics Of Waterproofing

Waterproofing implies applying a thick waterproof layer to the surface of the building structures and commercial/residential facilities to ensure thorough protection from water and corrosive liquids. Waterproofing boosts efficient operation of buildings, structures and equipment, increases their reliability and useful life.

From a functional point of reference there are two types of waterproofing to be defined: anti filtration one, designed for protection against the ingress of water into the underground and underwater structures, leakages of the operating, technical or waste water; and corrosion waterproofing that aims at protecting structures from chemically aggressive liquids and water, the harmful effects of the atmosphere.

By structural features waterproofing is divided into superficial, that aims at reinforcing structure interfaces, and multi-purpose one. By the type of material used, waterproofing is divided into asphalt, mineral, metal and plastic types.

By the method of waterproofing is subdivided into:

  • Paint waterproofing (hot and cold) is performed in the form of a thin, 2 mm multilayer coating commonly bituminous and polymeric coatings and paints for corrosion and anti-capillary protection of concrete and metal structures. The method is utilised in roof coating and roof waterproofing.
  • Backlining waterproofing, where roll materials produced as multilayers (and typically comprised of 3-4 layers) with mandatory protection coating surface and the wall ties.
  • Cast waterproofing, usually produced from a hot mix of asphalt mastic and casting. The solution is applied on horizontal bases (2-3 layers with an average thickness of 20 -25mm), filled to the walls or on the walls’ formworks (30 – 50mm thickness).

The Benefits Of Anticorrosive Paints Revealed

To provide protection against corrosion of reinforced concrete and steel structures, equipment, bridges, pipelines and storage tanks, one can resort to moisture-curing polyurethane systems. The innovative products, supplied to the market by seasoned players, such as Britannia Company, specialising in mass production of roof waterproofing and roof coating materials, provide unique properties that allow applying anti-corrosion coatings in the extreme conditions:

  • High humidity, up to 99%
  • Low temperatures (up to -7°C)
  • Applying to poorly refined metal surfaces with purity level starting from St2
  • Wet concrete surfaces
  • Applying the materials to old paint layers

Ultrasonic Cleaning Functionality Principles

Ultrasonic Cleaning Functionality Principles

Ultrasonic cleaning – method of cleaning the surface from solid and liquid contaminants is based on the excitation of ultrasonic frequency in the washing solution. The scientific basis for the creation and development of technology equipment ultrasonic cleaning laid in the field of acoustic cavitation conducted at the Acoustics Institute named after Academician Andreeva led by Professor Rosenberg.

Ultrasonic cleaning can replace manual labor, thereby speeding up the cleaning process, a high degree of surface smoothness virtually eliminate the use of inflammable and toxic solvents. Thus, according to Hilsonic statistics (the company is focusing its efforts on producing ultrasound equipment and ultrasonic cleaner models in particular) reports that despite the higher energy consumption and relatively high maintenance costs, its customers managed to cut down operational expenses by 18% on average.

Ultrasonic cleaning process provides its effect due to several phenomena that occur in the field of high intensity of ultrasound: acoustic cavitation, acoustic currents, radiation pressure and acoustic-capillary pressure.

Depending on the type of contamination, the predominant role is played by various purification processes. Thus, the destruction of contaminants occurs weakly interrelated, mainly under the influence of pulsating cavitation bubbles. On the edges of the film contamination pulsating bubbles, making intense vibrations, overcoming the cohesive forces of the film to the surface, penetrating the film and breaking it. Radiation pressure and acoustocapillary effect contribute to the penetration of cleaning solution in the micropores, bumps and blind channels. Acoustic flow is accelerated removal of dirt from the surface. If contamination is firmly connected to the surface, its elimination requires collapsing cavitation bubbles, creating a microshock impact to the surface.
