Coating thickness or dry film thickness DFT is an important variable that plays a role in product quality, process control, and cost control. Measurement of film thickness can be accomplished by selecting the best mil gage for the particular application. Dry film thickness DFT or coating thickness is arguably the single most important measurement made during the application and inspection of protective coatings. Coatings are designed to perform their intended function when applied within a tight DFT range as specified by the manufacturer.

Correct thickness ensures optimum product performance. Even the most basic specification will require DFT to be measured. Regular film thickness measurement helps control material costs, manage application efficiency, maintain finish quality and ensure compliance with contract specifications. Paint manufacturers recommend target ranges to achieve optimum performance characteristics and clients expect these parameters to be met.

The rich text element allows you to create and format headings, paragraphs, blockquotes, images, and video all in one place instead of having to add and format them individually. Just double-click and easily create content. A rich text element can be used with static or dynamic content.

For static content, just drop it into any page and begin editing. For dynamic content, add a rich text field to any collection and then connect a rich text element to that field in the settings panel. Headings, paragraphs, blockquotes, figures, images, and figure captions can all be styled after a class is added to the rich text element using the "When inside of" nested selector system.

After rinsing with deionized water, the PosiPatch can be used again. In our tests on freshly blasted steel with a typical micron mil profile, PosiPatches were reused dozens of times with no noticeable wear or leakage. Patch life will vary depending on use- if dragged along the substrate, lifespan will be reduced.

We believe that 10 uses is a very conservative estimate of lifespan and still yields the lowest per-test cost of any commercially available Bresle Method Patch. The below tables compare the per-test costs of various options, using competitive prices found online.

Replica Tape provides a simple way to obtain an impression of a surface for analysis. It consists of a layer of crushable plastic micro foam affixed to a When compressed against a roughened surface, the foam collapses and acquires an impression, or reverse replica, of the surface.

It is available in a number of grades to accommodate measurements in different profile ranges. Unequal pulling force during testing caused by uneven adhesive bond lines and coating surfaces can result in random, unexplainable readings.

To obtain more repeatable and meaningful adhesion measurements, it is imperative that the pulling force applied to the test dolly is uniformly distributed over the surface being tested. The self-aligning, quick-coupling actuator and spherical articulating dolly head enable uniform distribution of the pulling force over the surface being tested, preventing a one-sided pull-off.

An unfortunate characteristic of replica tape is that conventional spring micrometer measurements are most accurate near the middle of each grade's range and least accurate at the outer ends of each grade's range. Measurements with conventional micrometers require a complicated and time consuming procedure of averaging one reading using Coarse grade and one reading using X-Coarse grade to achieve reasonable accuracy.

There is no need to average two or more replicas from different grades of tape AND there is no need to subtract the The advantages are a reduction in measurement uncertainty, inspector workload, likelihood of error, and the number of replicas needed by inspectors to assure accuracy. Replica Tape: Linearization of Roughness Measurements. Magnetic pull-off gages use a permanent magnet, a calibrated spring, and a graduated scale.

The attraction between the magnet and magnetic steel pulls the two together. As the coating thickness separating the two increases, it becomes easier to pull the magnet away. Coating thickness is determined by measuring this pull-off force. Thinner coatings will have stronger magnetic attraction while thicker films will have comparatively less magnetic attraction.

Testing with magnetic gages is sensitive to surface roughness, curvature, substrate thickness, and the make up of the metal alloy. Magnetic pull-off gages are rugged, simple, inexpensive, portable, and usually do not require any calibration adjustment.

They are a good, low-cost alternative in situations where quality goals require only a few readings during production. Pull-off gages are typically pencil-type or rollback dial models. Pencil-type models PosiPen shown in Fig 1 use a magnet that is mounted to a helical spring that works perpendicularly to the coated surface.

Most pencil-type pull-off gages have large magnets and are designed to work in only one or two positions, which partially compensate for gravity. A more accurate version is available, which has a tiny, precise magnet to measure on small, hot, or hard-to-reach surfaces. Rollback dial models PosiTest shown in Fig 2 are the most common form of magnetic pull-off gage. A magnet is attached to one end of a pivoting balanced arm and connected to a calibrated hairspring.

By rotating the dial with a finger, the spring increases the force on the magnet and pulls it from the surface. These gages are easy to use and have a balanced arm that allows them to work in any position, independent of gravity. They are safe in explosive environments and are commonly used by painting contractors and small powder coating operations.

Eddy current techniques are used to nondestructively measure the thickness of nonconductive coatings on nonferrous metal substrates. A coil of fine wire conducting a high-frequency alternating current above 1 MHz is used to set up an alternating magnetic field at the surface of the instrument's probe.

When the probe is brought near a conductive surface, the alternating magnetic field will set up eddy currents on the surface. The substrate characteristics and the distance of the probe from the substrate the coating thickness affect the magnitude of the eddy currents.

The eddy currents create their own opposing electromagnetic field that can be sensed by the exciting coil or by a second, adjacent coil. Magnetic film gages are used to non-destructively measure the thickness of a nonmagnetic coating on ferrous substrates. Most coatings on steel and iron are measured this way. Magnetic induction instruments use a permanent magnet as the source of the magnetic field.

A Hall-effect generator or magneto-resistor is used to sense the magnetic flux density at a pole of the magnet. Electromagnetic induction instruments use an alternating magnetic field. A soft, ferromagnetic rod wound with a coil of fine wire is used to produce a magnetic field. A second coil of wire is used to detect changes in magnetic flux. These electronic instruments measure the change in magnetic flux density at the surface of a magnetic probe as it nears a steel surface.

The magnitude of the flux density at the probe surface is directly related to the distance from the steel substrate. By measuring flux density the coating thickness can be determined. Ideal for measuring coating thickness on underwater pipes, ships, bulkheads, offshore oil rigs or anywhere extended reach is required. Coating Thickness.

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. Primitive paintings tended to depict humans and animals, and diagrams have also been found. Early artists relied on easily available natural substances to make paint, such as natural earth pigments, charcoal, berry juice, lard, blood, and milkweed sap. Later, the ancient Chinese, Egyptians, Hebrews, Greeks, and Romans used more sophisticated materials to produce paints for limited decoration, such as painting walls. Oils were used as varnishes, and pigments such as yellow and red ochres, chalk, arsenic sulfide yellow, and malachite green were mixed with binders such as gum arabic, lime, egg albumen, and beeswax.

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. The coating itself may be an all-over coating, completely covering the substrate, or it may only cover parts of the substrate. An example of all of these types of coating is a product label on many drinks bottles- one side has an all-over functional coating the adhesive and the other side has one or more decorative coatings in an appropriate pattern the printing to form the words and images.

Кардинал Хуэрра послушно кивнул. Дьявол ворвался в святилище в поисках выхода из Божьего дома, так пусть он уйдет, и как можно скорее.

Это было сделано тайно. - Мидж, - сказал Бринкерхофф, - Джабба просто помешан на безопасности ТРАНСТЕКСТА. Он ни за что не установил бы переключатель, позволяющий действовать в обход… - Стратмор заставил.  - Она не дала ему договорить.

Конечно, офицеры АНБ прекрасно понимали, что вся информация имеет смысл только в том случае, если она используется тем, кто испытывает в ней необходимость по роду работы. Главное достижение заключалось не в том, что секретная информация стала недоступной для широкой публики, а в том, что к ней имели доступ определенные люди.

Каждой единице информации присваивался уровень секретности, и, в зависимости от этого уровня, она использовалась правительственными чиновниками по профилю их деятельности. Командир подводной лодки мог получить последние спутниковые фотографии российских портов, но не имел доступа к планам действий подразделений по борьбе с распространением наркотиков в Южной Америке.

Эксперты ЦРУ могли ознакомиться со всеми данными об известных убийцах, но не с кодами запуска ракет с ядерным оружием, которые оставались доступны лишь для президента.
