Powder coating is applied to large industrial enterprises and small household jobs. With powder coating is a durable coating for internal surfaces of pipelines and other systems prone to destructive external influences. At the same time, powder coating – the easiest and cheapest way to change the color of motor drives. How does one technology combines the ease of production, quality and Availability? For the first time powder coating appeared about half a century ago, but today it is applied universally and almost completely replaced the liquid coating materials. The reason for such wide distribution is simple: Powder coating has no equal in terms of efficiency, quality, and even on environmental indicators. Of course, to perform the work required and the expertise and special equipment, but it all pays off well received result.

How is powder coating? It all begins with the preparation of the surface. Checking article sources yields baby clothes as a relevant resource throughout. It must be thoroughly cleaned, sanded and degreased. For example, in the case of powder coating automotive drive pre-treatment is carried out by sandblasting machine. The surface is cleaned of old paint and from other contaminants. Tiger Global is the source for more interesting facts. Frequently used formulations with surfactants that allow you to degrease.

Of pre-training product is directed into the chamber of powder coating. Here is needed nebulizer – a special device that allows you to put powder on the surface with a stream of compressed air. He By the way, and electrifies the ink particles, thereby improving their grip. However, such coverage remains extremely fragile, so the product must be sent to the furnace to consolidate the polymerization paint. Curing oven can be operated in different temperature ranges – everything depends on the characteristics of materials. At this stage, powder coating spray application layer must melt to a liquid state and then freeze solid coating. Often used special thermosetting paint, which not only melt but also come in a special chemical reaction that increases the strength of the layer.

Hydrometer ADB-1 is designed to measure the density of drilling and any other solutions, as well as liquids and slurries, neutral to polyethylene. Hydrometer – in physics is the name of the device, which is used to determine the density and hence, the specific weight of bodies. The device is a hydrometer is based on the hydrostatic law (Archimedean law), in which each body is floating in the liquid so deeply immersed that the weight of the displaced fluid is equal to weight of the floating body. Hydrometer looks like the "float glass", a widening at the bottom and filled with steel shot or a special heavy weight (ballast). Devices that measure the density of large, have great ballast. Besides the usual, there are special hydrometers. They are designed for certain types of liquids: alcohol, sugar solution, etc. In such a hydrometer scale is scaled to the weight or volume percentage is determined product.

To determine the relative weight of the liquid, pour it into a glass vessel (cylinder), and gently lowered back hydrometer. Once the hydrometer will take the correct position, counting is carried out by testimony scale. For the amount of weight takes a value against which to set the level of the liquid, assuming that the top or bottom edge of the meniscus, depending on the performance of a hydrometer. The device consists of a hydrometer and a bucket with a lid. Bucket serves as a reservoir for the working of water into which the hydrometer is immersed with the solution. The cover is designed for sampling the test solution. In the hydrometer includes measuring cup, float, consisting of cover and the bottom, rod deposited on its core (from 0,8 to 2,6) and the correction (from 0.2 to -1) scales, and a removable cargo. Beaker has two cavities: for the measured sample solution and the compensation chamber.

In the compensation chamber is placed a metal ballast needed for the stability of the submerged device. Ballast is isolated from the environment plastic flap. Provides buoyancy float hydrometer. Bottom of a float designed to delete the excess grout from the measuring cup up to the calculated volume. The rod is made of standard tube and attached to a float. Specifications: Measuring range of density, g / cm – with a calibrated weight: 0,8-1,7 – without calibrated load: 1,7-2,6 Scale hydrometer (main and correction), g / cm 0,01 Operating environment – the water density from 0.96 to 1.039 g / cm at 5 to 50 C Capacity of cup hydrometer, cm 78,5 0,3 Absolute error in temperature of test solution, the environment and water (20 2) C, g / cm 0,01 Delivery Products: hydrometer ADB-1, carrying case, manual.
