Dalam bentuk film bubuk digunakan dalam lapisan tipis workpiece kemudian dilarutkan dalam bentuk film dan dipanaskan untuk polimerisasi dan mengawetkan coating. The powder coating process was invented around 1945 by daniel gustin and received us patent 2538562 in 1945.

They come under the category of protective coatings in paints and coating nomenclature.

Powder coating process wikipedia. The powder partially melts in the stream and deposits upon the substrate. Yang terdiri dari partikel partikel yang dihaluskan seperti resin pigmen dan bahan baku lainnya yang diberikan muatan elektrostatis kemudian disemprotkan ke objek yang akan dilapisi atau di cat. The resulting coating has low porosity and high bond strength.

Powder coating adalah proses finishing kering. This process puts a coating on an item electrostatically which is then cured by heat. Fusion bonded epoxy coating also known as fusion bond epoxy powder coating and commonly referred to as fbe coating is an epoxy based powder coating that is widely used to protect steel pipe used in pipeline construction concrete reinforcing bars and on a wide variety of piping connections valves etc.

Common roll to roll coating processes include. Electrostatic coating is a manufacturing process that employs charged particles to more efficiently paint a workpiece. The name fusion bond epoxy is due to resignin.

A powder feed stock is injected into the gas stream which accelerates the powder up to 800 m s. Hot melt coating when the necessary coating viscosity is achieved by temperature rather than solution of the polymers etc. Powder coating teknik pengecatan powder coating adalah teknik pengecatan kering pelapisan dengan suatu film.

This method commonly implies slot die coating above room temperature but it also is possible to have hot melt roller coating. Powder coating on glass is a specialized procedure related to traditional powder coating which is the technique of applying electrostatically charged dry powdered particles of pigment and resin to a solid item s surface. Paint in the form of either powdered particles or atomized liquid is initially projected towards a conductive workpiece using normal spraying methods and is then accelerated toward the work piece by a powerful electrostatic charge.

The stream of hot gas and powder is directed towards the surface to be coated. It requires its own unique process however because glass is a poor electrical conductor in comparison to metal the traditional powder coating substrate. The common forms of powder coating.

Gap coating knife over roll coating. Fbe coatings are thermoset polymer coatings. The finish is harder and tougher than conventional paint.
