Almost most people now know and use all kinds of kitchen tool which has been coated with "Teflon". A thin layer of Teflon is a polymer containing fluorine atoms. Due to the size of the fluorine atom and the electronic properties of these polymers have special physical properties more than most polymers, such as resistance to heat, ultraviolet light and weather, inert to acids and bases as well as some other electrical and optical properties
Studies whitening strips conducted in recent years increasingly whitening strips placing a fluorine atom at position especially important in materials technology modifications to the physical whitening strips properties of the surface. Many advantages to be gained by placing the fluorine atoms on the surface of a material. whitening strips Some examples of development whitening strips that is now being done is, the surface modification of heterogeneous catalysts, for example, silica-alumina and oxides of transition metals, plastics whitening strips and fiber surface modification, surface modification of carbon materials and so on. Regardless, there are many natural and industrial materials that can be modified.
In heterogeneous catalyst modification, the term fluorine atoms attached to the active centers are of course contained in particulate catalyst surface. Fluorine atoms that have high electronegativity will increase the Lewis acidity properties of active centers whitening strips are very important in the process of catalysis. Plastics that have been added fluorine atom has adhesion properties and kedapat-basahan higher surface so that the coloring process easier (eg for vehicle components and architectural panels). Similarly, due to the size of the fluorine atom is slightly larger than hydrogen and can arrange themselves in meetings, fluorine atom layer can withstand exposure to ultraviolet light and weather exposure so that after the plastic has a longer life. Besides the selectivity of polymer membranes whitening strips can also be set with the addition of fluorine atoms.
There are several methods whitening strips of addition of fluorine atoms is quite widely applied in research. whitening strips Two common ways and quite useful for industrial scale is to simply make contact between the material and fluorine gas at various contact time, temperature, pressure and concentration of the reactant gas. Fluorine gas is one of the most reactive whitening strips gas that can react with the atoms on the surface of the material. The method seems more complicated whitening strips example with the help of radio wave radiation (microwaves), whitening strips as a tool of radical forming compounds and fluorohidrokarbon fluorocarbon gas (CF 4, CHF 3, and so on). This latter technology is often referred to as "Cold Plasma-Enhanced fluorination". whitening strips The advantages of these methods rather than the conventional way with an ordinary chemical reaction is handling the process is easy, no need for fluorine compounds are complex and expensive as the reactants, and of course we can choose a variety of materials with ease.
