You Ever Think About How Do Batteries Work?

on May 28th, 2010

We use batteries almost daily in one form or another. They could be your car battery, rechargeable batteries in electronic devices or dry cell batteries. What we may not do is consider how do batteries work. What is it about them that gives them power?

Those C, D and AA batteries are called dry cell because they use a paste made up of powdered chemicals. The Alkaline type use an alkaline electrolyte. The voltage which range from 1.5 to 9 volts is dependant on the number of cells and the metal used for the electrodes. The battery creates a chemical reaction which produces the electrical current.

Rechargeable batteries have a reversible chemical property. When the battery is charged again after it goes dead, it is allowed to reverse itself to hold a charge again. This is a pretty basic explanation on how these work.

What makes lithium batteries so popular? They are much lighter than other types of rechargeable batteries. The electrodes are made from highly reactive lithium and carbon and can store a lot of energy. By comparison a lithium battery might store 100 watt-hours per kilogram where a lead acid battery might store 25 watt-hours.

The downside to lithium batteries is that they have a life span of about 2 or 3 years whether you use them or not. They are sensitive to high temperatures which can shorten their life. You should not allow the battery to fully discharge because it may ruin them. At the extreme, there have been some rare instances of lithium batteries bursting into flames.

A Temperature Guide for Epoxy Floor Installation

on May 3rd, 2010

Manufactures epoxy floor paint is composed of two components: the rule of the Under-treatment. You must be a hybrid of these components in determining the ratio established by the manufacturer of the product. This confusion creates a chemical reaction that generates heat and solidify the mixture. The properties of these coatings, such as life, pot, and viscosity, hardening time, etc., are closely linked to the temperature of the components at the time were mixed. For this reason, when mixing them, it is important for you to recognize the relationship between temperature and characteristics of this epoxy. Refer to the information below mix correctly and use of these coatings.
Tip 1 – pot life and cure time

In general, epoxy and mixtures become difficult within minutes or hours after being mixed, depending on the recommendations of the mixing of their manufactures. But you can organize, modify, and this extremism (recovery) time or pot life by changing the temperature while you’re mixing with them. For example: to extend the 100 per cent in the time of the treatment that you are using epoxy coating, low temperature of 18 degrees Fahrenheit to reduce the recovery time by 100 percent, and increased temperature of 18 degrees Fahrenheit.
Tip 2 – viscosity

You can make epoxies more user friendly and easier to work with if you keep in temperatures ranging from 60 degrees to 70 degrees Fahrenheit, while you are working with them in their liquid. At a higher temperature and will become thinner and will harden faster, giving you less time working. Drop in temperature, they thicken and give you longer work.
Tip 3 – Epoxies temperature for

If you prefer to work with these cases, coatings under the temperature in particular, you may need a product that will perform better in colder or warmer environments. If so, keep in mind that some are designed for the treatment of epoxy coating at temperatures as low as 35 degrees Fahrenheit.
Tip 4 – Chemical resistance

In the projects that you expect that you need to epoxy that is resistant to corrosion, especially in use with steel and concrete, and there are layers provided for this use. Where you need epoxies that work well with chemicals at temperatures reaching 300 degrees or in the water when temperatures reach 212 degrees, you can find these special coatings.
Tip 5 – Softening

In the application of epoxy paint, take account of the likely characteristics of epoxy coatings after they have cured (hardened). These coatings retain hardness and durability at temperatures below zero degrees Fahrenheit, but it’s not permanent, as is the case in the high temperatures. Some epoxies begins to soften at temperatures as low as 140 degrees. These same coatings will harden again as the temperature is reduced, but for applications where extreme temperatures are likely, we must look for epoxy coatings that are manufactured specifically for use in extreme temperatures, low or high.
Tip 6 – Shipping and freight

Must be classified as epoxy paint that need to be shipped. Overall, the highest quality paint does not require a Haz – mat (hazardous materials) and classification of ships. But that is classified as a high temperature or UV-resistant paint, requiring in some cases, Haz mat freight will increase in many cases, the purchase price.

Paint And Environmental Considerations

on April 21st, 2010

There are two basic types of paint to choose from: water-based paints, often referred to as acrylic emulsions, and solvent-based paints. High-quality water-based paints offer not just an excellent all-round performance profile, they are also a good choice from an environmental perspective.

Solvent-based paints, the more traditional type of paint, require users to excercise a degree of caution to avoid potential damage to the environment.

Solvent-based paints are a source of potentially hazardous emissions called Volatile Organic Compounds (VOCs), a family of substances that easily evaporate into the air to form invisible vapours.

When evaporating, the solvents contained in paint emit VOCs into the atmosphere. VOCs react with oxygen in the presence of sunlight to form ozone – “bad” ozone.

It is important to distinguish between “good” ozone and “bad” ozone.

“Good” ozone occurs naturally in the stratosphere about 10-35 kilometres above the ground, which protects the surface of the earth from harmful ultraviolet rays and acts to protect plants, animals and humans from its various harmful effects.

“Bad” ozone occurs at ground level, forms through the chemical reaction between VOCs, oxygen and sunlight, and is an irritant for the mucous membranes. It can also cause nose, eye, and throat irritations; and can lead to shortness of breath, coughing, and asthmatic symptoms.

This “bad” lower-atmosphere ozone can also damage vegetation – plants, trees, bushes – and such impacts negatively on those dependent on nature for their livelihood. This ozone also has a corrosive effect on certain man-made materials: for example, it accelerates the deterioration and fading of certain paints.

A further major consequence of VOC emissions is global warming – VOCs play a significant role with respect to the creation of the greenhouse effect. Further, some chemically very stable VOCs participate in the destruction of the stratospheric ozone layer (the “good ozone”): this is the famous hole in the ozone layer.

According to a study of the C.E.P.E (Conseil Europeens de L’Industrie des Peintures, des Encres, d’Imprimerie et des Couleurs d’Art) roughly 4 to 5 % of total VOC emissions are linked to the manufacture.

How You Can Choose The Decorative Concrete Application?

on March 31st, 2010

There are hundreds of different Decorative concrete applications. Naturally, it can be very confusing to choose the right option among them. Yet, this is the most important factor that you have to do to make the most of them. So, it is very important that you learn something about the different options that are available to you. That will certainly help you choose the right one for you. Now, if you are not quite aware of them, take a look at the following lines and learn about them.

The first and one of the most popular options in this regard is the form lining. This is one of the applications that require the touch of an artist. Here, the decorative forms are actually molded by sculptors following certain design or sculptor. Great care needs to be taken at that time. After that, these molds are used to create impression on the surface. What makes it even more appealing is the brilliant combination of colored molds and colourless cement.

The next option is called the mixed aggregates. This is one of the most well known methods that are available in the market today. Well, one of the reasons why it is so preferred is the fact that it is very easy to prepare. During the preparation, it requires the colouring agents along with the cement. Sometimes, the solid aggregates are used too, with cement to create the different interesting shades and patterns on the surface.

Another very common method to decorate the concrete is the stamping. In this process, the wooden or stone stamps are used to make impressions on the concrete. However, this must be done before the concrete is settled. These stamps are specially designed and they include special liquids or powders to ensure that they don’t get stuck to the surface of the concrete slab. Eventually, the stamp is removed from the slab and you will get the impression on the surface. There are different textures that can be created with these stamps and this includes bricks, stones and so on.

Acid staining is another very well known process of decorating the concrete. In this process, the acidic solution is applied on the concrete. It results in the chemical reaction with lime and other materials present inside the concrete and eventually alters their shades. This is one brilliant way of decorating the concrete. Since the structure of those elements inside a concrete is never the same with another, each of the concrete slab will create different textures and thus give an exclusive look. Also, there is no chance of the color getting faded by sunlight or other such factors.

There are some other options available apart from this as well. For example, there is an advanced technology called the water stain. This is the latest invention that uses different chemicals to create impressions similar to the acid stain. However, the way it works is different from acid stain.
