Whenever one requires to do powder coating Los Angeles should never be skipped in the list of probable locations to check out. Powder coating is the exercise of applying dry, powdered coats on a surface in their free flowing forms. Dry, powdered coats are same as other ordinary liquid paints with the distinction that the formers do not need solvents to be useful.
Powdered paint may be used to paint several kinds of equipment ranging from automobile parts to household appliances. More research shows that other substrates such as medium density fiberboards may also be coated using various processes. Apart from metals, plastics and ceramics can also be painted using this procedure. The application process involves three major phases with the actual application being performed using electronic guns.
The three steps entailed in the application process are surface preparation, actual application, and lastly curing. Surface preparation is important before application because it removes oil, grease, dirt, dust, metal oxides, mold, and welding scales among other unwanted materials. Preparation can be done through various chemical and mechanical techniques. The method used should be dictated by material and size of the object, type of dirt to be eliminated, and use of the end product.
Chemical treatment entails use of chromates and/or phosphates in spray and/or submersion application. This is performed in multiple stages and involves de-smutting, degreasing, etching, various rinses, and phosphating and/or chromating of the item as the final procedure. Pre-treatment is vital since it cleans and improves the bonding capability of the coat to substrates. Use of chromate compounds is being avoided as they are dangerous to the environment.
The key and most popular way of applying powdered coats onto substrates entails utilizing electrostatic or corona guns. Guns positively charge particles in the paints as they are emitted at the nozzles. Positive particles are then pushed to the substrate by compressed air and/or mechanical mechanisms. Electrostatic charges act to further accelerate particles. There are diverse types of nozzles that could be used to attain certain application requirements.
Another technique of applying powder form paint is known as fluidized bed method. This method entails heating the substrate to very high temperatures and then passing it through an aerated bed filled with the powdered coat. As the paint makes contact with the hot substrate, it melts and sticks onto it. Further heating is necessary to complete the curing process. Fluidized bed method is necessary if the thickness of the coat is supposed to be more than 300 micrometers.
The powdered films may be eradicated using chemical compounds like as methylene chloride. Many organic solvents are however observed to be ineffective in eliminating the paints. Due to the carcinogenic properties of methylene chloride, it is being substituted with benzyl alcohol. Abrasive blasting might also be utilized to eradicate coats. The substrates could be re-powdered after the surface is cleaned.
When in need of professionally done powder coating Los Angeles is the right place to check out. Companies in this region have high levels of expertise in this process. They can be hired for customized work on any kind of object.
