Advantages Of Buying A Cheap Smart Tv Than Traditional Tv

The DVDs and blue rays are still holding the strong market because the endless use of television streaming in your homes. The new gaming systems coming out every year because we are living in second golden age of televisions. You are missing a lot of great stuff if your TV is couple of years old or you are having a traditional TV. So exchange your old traditional TV with new smart TV or buy cheap smart TV in Nairobi as they give you best.

Smart TVs are different from traditional TVs, the reasons that you should buy cheap smart TV in Nairobi as they give you more advantages than buying a traditional TV as smart TVs also offers the access to the apps, games and internet protocol television (iPTV), you can easily have an access to these smart TVs as they are available all the time in the market. You can also buy cheap smart TV in Nairobi which will give a change to your lifestyle. Smart TV deliver the content like photos, movies and music from other computers by the use of digital living network or the use of storage devices, it also have feature of additional interactive user interface, technologies for navigation controls and human interaction with smart TV. These second screen companion device even helps you for speech recognition in different languages for natural language user interface.

The technological convergence between computers and flat screen TV sets and set top boxes is known as smart TV. Smart TV offers many multiple services that an ordinary traditional TV can’t, the name hybrid TV is given to the technologies that can connect the features of internet web to the television set. The traditional television sets and set top boxes function provides traditional broadcasting media but the smart TVs provides the best internet TV, online interactive media, over the top content (OTT) and demand streaming media to the home network access. The smart television industry survives in the battle of specification considering that there is only that much that a TV set can do, the smart television are increasingly being sold on the features like resolution, connectivity and advance features so don’t late to buy cheap smart TV in Nairobi.

Aside from applications, the smart TVs do have other additional benefits that it offer other potential feature of build-in computers and an online connection. The manufacturers can add common games like angry birds that attract the kids to replace the play stations. The use of build-un camera and additional video-camera accessory, with some advanced software some high-end smart TVs offer video calling services through Skype that helps business executives for their meetings and conferences. Food apps can helpful for the professional chef and house wives that love to cook food while sports person will cheer the dynamic food app. The fitness app is also available that helps to make you fit at home without joining gyms, you can stay in shape with this app installed in you smart TV.

Other powerful processors search voice and gesture recognition for screen switching. These advantages convince you to exchange old traditional TV and buy cheap smart TV in Nairobi.

Construction of Lead Acid Battery

As such the main battery container containing sulfuric acid and therefore material for the manufacture of lead-acid batteries of the vessel must be resistant to sulfuric acid. The material from which the container should be free also affects those impurities of sulfuric acid. Especially iron and manganese will not be tolerated. Glass, lead-lined timber, hard rubber, hard rubber asphalt compound, ceramic materials and molded plastic having the above characteristics, so lead-acid battery container is formed from any of those species. The container was tightly sealed with the cap. Because of these characteristics people buy cheap lead acid battery in Nairobi.

The upper deck has three holes, a shed on each side of the posts and in the middle for vent plug and allowing the electrolyte and gases escape. On inner bottom floor of lead acid battery holder, two ridges to grip the positive lead acid battery plates and a further two ribs keep the negative plates. The ridges or prisms serve as support for the plates while protecting them against short circuits arise otherwise because of the fall of the active material of the plates at the bottom of the container. The container is most basic part of the construction of lead acid battery

Lead Acid Battery Plates

There are generally two methods of producing the active material of the cell and attach it leads to records.  We know the names of their inventors.

Plant Plate

Plant process

This process took two sheets of lead and plunged into dilute H2SO4. When a current in the lead acid cell transferred from an external supply, then as a result of electrolysis, hydrogen and oxygen are developed. At anode, put pilot oxygen attacks in PbO2 while cathode is unaffected because hydrogen is not connected with Pb may form.

If the cell is now discharged and peroxide-coated cathode plate becomes, so the hydrogen form and oxygen combine to form lead dioxide water, PB2 + 2H2 → Pb + 2H2O

Meanwhile, the oxygen feed to the anode lead and PbO2 is formed by the reaction. Thus, the anode becomes lead dioxide film covering.

By reversing the current, or by continuous charging and discharging of the film will become increasingly thick PbO2, cell polarity will require increasingly long time to reverse. After two stereotype by hundreds reversal will acquire lead peroxide sufficiently thick enough to handle high-capacity skin. Production of a positive electrode plate formed of a process called. The negative electrode plate of lead-acid battery is the same process.

Structure of Plant Plate

As can be seen, since the active material consists of a Plant plate formed with a thin layer from the surface of the lead plates PbO2, it must be expected to have a large surface area, to get it a significant volume. Surface area of ​​the lead-acid battery plates can be increased by slots or stacked. The figure shows the Plant positive plate pure lead grid which consists of finely laminated surface. The structure of these panels is reinforced by laminating a large number of fine vertical ribs which is incorporated by horizontal interval

Faure Plate

Faure in the process, the active material is applied mechanically, rather than by the electrolysis itself developed as a lead plate Planet process. Active substance, it is in the red lead (Pb3O4) or a lead oxide (PBO) or both as a mixture of various proportions were pressed into a thin gap also serves as a lead grid current conductor. Paste with the active material of the plate was dried, cured and assembled at the gate of the proportion of weak sulfuric acid solution after. Lead batteries must be long-term affordability of inactivity, with or without an electrolyte solution. Long-term storage, if present in the cell solution may result in insufficient power. This motivates people to buy cheap lead acid battery in Nairobi.
