An alternative approach to pan coatings that provides the mixing and drying characteristics required by the film coating process is to use fluid bed technology. Fluid bed technology helps in achieving fast and uniform coating using air to mix, coat and dry the substrate at the same time.

This technology originated from fluid bed dryers used for wet powder material drying operation. Fluid bed equipment was modified to coat tablets as an alternative innovation. However, this modification did not become popular for film coating tablets. The major concern during tablet coating using fluid bed equipment was high friability and compromise in core tablet appearance due to physical stress imparted during the fluidization process, compared to the much gentler pan coating process.

The figure below shows diagrammatic representation of the fluid bed coating process by a bottom spray method which is widely used to film coat multiparticulate systems.

The existence of these three processing concepts has resulted in the major suppliers of fluid bed equipment offering all three as standard inserts for a basic fluid bed processing unit. The schematic diagram above illustrates the salient features of the three basic approaches.

A summary of advantages, limitations and applications for each process is given in the table below:. Your search did not return any results. The Colorcon Product Code you provided may be invalid or obsolete, or an MSDS may not be immediately available with the attributes that you selected.

Fluid Bed Coatings An alternative approach to pan coatings that provides the mixing and drying characteristics required by the film coating process is to use fluid bed technology. The air is taken out of the equipment from the exhaust filters mounted on the top of the equipment. The material to be coated is loaded in the fluid bed chamber and fluidized. The inlet air is maintained at a certain velocity and temperature to help in both fluidization of the material as well as its drying during the coating operation.

In this process, there is a concurrent same direction movement of powder particles or pellets and liquid spray. Granulator Process Top spray Most commonly used type of fluid bed process for granulation.

In this process, there is a counter current opposite direction movement of powder particles or pellets and liquid spray. Rotor Process Tangential spray Originally designed for the preparation of granulates pellets , this process has also become adapted for the film coating of multiparticulates.

In this process, the powder particles or pellets move in a helical fashion due to spinning rotor disk on the bottom of the equipment. The liquid is sprayed within the moving powder or pellets.

ASTM's paint and related coating standards are instrumental in specifying and evaluating the physical and chemical properties of various paints and coatings that are applied to certain bulk materials to improve their surface properties. Guides are also provided for the proper methods of applying these coatings, which also include enamels, varnishes, electroplatings, pigments, and solvents. These paint and related coating standards help paint manufacturers and end-users in the appropriate testing and application procedures for the coating of their concern.

A coating is a covering that is applied to the surface of an object, usually referred to as the substrate. The purpose of applying the coating may be decorative, functional, or both.

Materials processing , the series of operations that transforms industrial materials from a raw-material state into finished parts or products. Materials processing by hand is as old as civilization; mechanization began with the Industrial Revolution of the 18th century, and in the early 19th century the basic machines for forming, shaping, and cutting were developed, principally in England. Since then, materials-processing methods, techniques, and machinery have grown in variety and number. The cycle of manufacturing processes that converts materials into parts and products starts immediately after the raw materials are either extracted from minerals or produced from basic chemicals or natural substances. Metallic raw materials are usually produced in two steps. First, the crude ore is processed to increase the concentration of the desired metal; this is called beneficiation.

An apparatus has been developed to measure the thermal conductivity of ceramic coatings. This steady-state, comparative measurement method uses the known thermal conductivity of the substrate material as the reference material for heat-flow measurement. The experimental method is validated by measuring a plasma-sprayed coating that has been previously measured using an absolute, steady-state measurement method.

Paint is a term used to describe a number of substances that consist of a pigment suspended in a liquid or paste vehicle such as oil or water. With a brush, a roller, or a spray gun, paint is applied in a thin coat to various surfaces such as wood, metal, or stone. Although its primary purpose is to protect the surface to which it is applied, paint also provides decoration. Samples of the first known paintings, made between 20, and 25, years ago, survive in caves in France and Spain.

Элвин едва обратил внимание на эти слова; он был глубоко погружен в собственные мысли, пытаясь припомнить все когда-либо слышанное о Шалмиране. Впрочем, вспомнить удалось немногое: спустя столь огромное время никто не мог отличить истину от легенды. Достоверно известно было лишь одно: Битва при Шалмиране ознаменовала конец завоеваний Человека и начало его долгого отступления.
