Polymetallic driers for paintwork materials. Production and sale in Ukraine.

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. Paint was first used as a protective coating by the Egyptians and Hebrews, who applied pitches and balsams to the exposed wood of their ships.

During the Middle Ages, some inland wood also received protective coatings of paint, but due to the scarcity of paint, this practice was generally limited to store fronts and signs. Around the same time, artists began to boil resin with oil to obtain highly miscible mixable paints, and artists of the fifteenth century were the first to add drying oils to paint, thereby hastening evaporation. They also adopted a new solvent, linseed oil, which remained the most commonly used solvent until synthetics replaced it during the twentieth century.

In Boston around , Thomas Child built the earliest American paint mill, a granite trough within which a 1. The first paint patent was issued for a product that improved whitewash, a water-slaked lime often used during the early days of the United States.

In D. Flinn obtained a patent for a water-based paint that also contained zinc oxide, potassium hydroxide, resin, milk, and lin-seed oil. The first commercial paint mills replaced Child's granite ball with a buhrstone wheel, but these mills continued the practice of grinding only pigment individual customers would then blend it with a vehicle at home. It wasn't until that manufacturers began mixing the vehicle and the pigment for consumers.

The twentieth century has seen the most changes in paint composition and manufacture. Today, synthetic pigments and stabilizers are commonly used to mass produce uniform batches of paint.

New synthetic vehicles developed from polymers such as polyurethane and styrene-butadene emerged during the s. Alkyd resins were synthesized, and they have dominated production since. Before , pigment was ground with stone mills, and these were later replaced by steel balls. Today, sand mills and high-speed dispersion mixers are used to grind easily dispersible pigments. Perhaps the greatest paint-related advancement has been its proliferation. While some wooden houses, stores, bridges, and signs The first step in making paint involves mixing the pigment with resin, solvents, and additives to form a paste.

If the paint is to be for industrial use, it usually is then routed into a sand mill, a large cylinder that agitates tiny particles of sand or silica to grind the pigment particles, making them smaller and dispersing them throughout the mixture. In contrast, most commercial-use point is processed in a high-speed dispersion tank, in which a circular, toothed blade attached to a rotating shaft agitates the mixture and blends the pigment into the solvent. Today, paints are used for interior and exterior housepainting, boats, automobiles, planes, appliances, furniture, and many other places where protection and appeal are desired.

A paint is composed of pigments, solvents, resins, and various additives. The pigments give the paint color; solvents make it easier to apply; resins help it dry; and additives serve as everything from fillers to antifungicidal agents. Hundreds of different pigments, both natural and synthetic, exist.

The basic white pigment is titanium dioxide, selected for its excellent concealing properties, and black pigment is commonly made from carbon black. Other pigments used to make paint include iron oxide and cadmium sulfide for reds, metallic salts for yellows and oranges, and iron blue and chrome yellows for blues and greens.

Solvents are various low viscosity, volatile liquids. They include petroleum mineral spirits and aromatic solvents such as benzol, alcohols, esters, ketones, and acetone. The natural resins most commonly used are lin-seed, coconut, and soybean oil, while alkyds, acrylics, epoxies, and polyurethanes number among the most popular synthetic resins.

Additives serve many purposes. Some, like calcium carbonate and aluminum silicate, are simply fillers that give the paint body and substance without changing its properties. Other additives produce certain desired characteristics Paint canning is a completely automated process. For the standard 8 pint paint can available to consumers, empty cans are first rolled horizontally onto labels, then set upright so that the point can be pumped into them.

One machine places lids onto the filled cans while a second machine presses on the lids to seal the cons. From wire that is fed into it from coils, a bailometer cuts and shapes the handles before hooking them into holes precut in the cans. Paint is generally custom-made to fit the needs of industrial customers. For example, one might be especially interested in a fast-drying paint, while another might desire a paint that supplies good coverage over a long lifetime.

Paint intended for the consumer can also be custom-made. Paint manufacturers provide such a wide range of colors that it is impossible to keep large quantities of each on hand. To meet a request for "aquamarine," "canary yellow," or "maroon," the manufacturer will select a base that is appropriate for the deepness of color required.

Pastel paint bases will have high amounts of titanium dioxide, the white pigment, while darker tones will have less. Then, according to a predetermined formula, the manufacturer can introduce various pigments from calibrated cylinders to obtain the proper color. Paint manufacturers utilize an extensive array of quality control measures.

The ingredients and the manufacturing process undergo stringent tests, and the finished product is checked to insure that it is of high quality. A finished paint is inspected for its density, fineness of grind, dispersion, and viscosity. Paint is then applied to a surface and studied for bleed resistance, rate of drying, and texture.

In terms of the paint's aesthetic components, color is checked by an experienced observer and by spectral analysis to see if it matches a standard desired color.

Resistance of the color to fading caused by the elements is determined by exposing a portion of a painted surface to an arc light and comparing the amount of fading to a painted surface that was not so exposed. The paint's hiding power is measured by painting it over a black surface and a white surface. The ratio of coverage on the black surface to coverage on the white surface is then determined, with.

Gloss is measured by determining the amount of reflected light given off a painted surface. Tests to measure the paint's more functional qualities include one for mar resistance, which entails scratching or abrading a dried coat of paint.

Adhesion is tested by making a crosshatch, calibrated to. A piece of tape is applied to the crosshatch, then pulled off; good paint will remain on the surface. Scrubbability is tested by a machine that rubs a soapy brush over the paint's surface. A system also exists to rate settling. An excellent paint can sit for six months with no settling and rate a ten. Poor paint, however, will settle into an immiscible lump of pigment on the bottom of the can and rate a zero.

Weathering is tested by exposing the paint to outdoor conditions. Artificial weathering exposes a painted surface to sun, water, extreme temperature, humidity, or sulfuric gases. Fire retardancy is checked by burning the paint and determining its weight loss. If the amount lost is more than 10 percent, the paint is not considered fire-resistant.

A recent regulation California Rule 66 concerning the emission of volatile organic compounds VOCs affects the paint industry, especially manufacturers of industrial oil-based paints. It is estimated that all coatings, including stains and varnishes, are responsible for 1. The new regulation permits each liter of paint to contain no more than grams 8. Paint manufacturers can replace the solvents with pigment, fillers, or other solids inherent to the basic paint formula.

This method produces thicker paints that are harder to apply, and it is not yet known if such paints are long lasting. Other solutions include using paint powder coatings that use no solvents, applying paint in closed systems from which VOCs can be retrieved, using water as a solvent, or using acrylics that dry under ultraviolet light or heat. A consumer with some unused paint on hand can return it to the point of purchase for proper treatment.

A large paint manufacturer will have an in-house wastewater treatment facility that treats all liquids generated on-site, even storm water run-off. The facility is monitored 24 hours a day, and the Environmental Protection Agency EPA does a periodic records and systems check of all paint facilities. The liquid portion of the waste is treated on-site to the standards of the local publicly owned wastewater treatment facility; it can be used to make low-quality paint.

Latex sludge can be retrieved and used as fillers in other industrial products. Waste solvents can be recovered and used as fuels for other industries. A clean paint container can be reused or sent to the local landfill. Flick, Ernest W. Handbook of Paint Raw Materials, 2nd ed. Noyes Data Corp. Martens, Charles R.

Working closely with our customers of monometallic driers, we have soon realized that final user is not always convenient to deal with them, that is prepare mixture of driers by oneself. Therefore, along with monometallic we have developed a number of formulations of polymetallic mixed driers, which are based on 2-ethylhexanoate "desiccant" metals cobalt, manganese , and various promoters. It should be emphasized that they do not contain lead compounds. Generally the amount injected into the desiccant coatings is calculated from the ratio of active metal and film-former, as it is well- known that effect of desiccant in the film-forming system largely depends on its quantity.

Eskaro Group AB is an international company that produces paintwork materials.

Materials Science. We present a survey of the literature data on the scientific and practical aspects of the production and use of waterborne paintwork materials and show that these materials can successfully compete with paints soluble in organic solvents. Waterborne paints prove to be one of the most important classes of environmentally safe paintwork products and are extensively used abroad in various branches of industry and national economy as decorative, protective, corrosion-resistant coatings, etc. We describe the prospects of the development of production of waterborne paintwork materials in the Ukraine.

RAW MATERIALS FOR PAINT MANUFACTURING

Paint is any pigmented liquid , liquefiable, or mastic composition that, after application to a substrate in a thin layer, converts to a solid film. It is most commonly used to protect, color, or provide texture to objects. Paint can be made or purchased in many colors—and in many different types, such as watercolor or synthetic. Paint is typically stored, sold, and applied as a liquid, but most types dry into a solid. Most paints are either oil-based or water-based and each have distinct characteristics.

Он снова припомнил горькие слова Сирэйнис: И он и я будем мертвы уже целые столетия, в то время как вы будете еще молодым человеком. Что ж, хорошо: он примет эти условия.

Немалую часть времени Хилвар потратил на выслеживание Крифа, который то и дело исчезал в джунглях или стремительно мчался над водой. Даже Элвин, которому все было пока в диковинку, смог почувствовать, что здешний лес обладает незнакомыми чарами, не свойственными небольшим, ухоженным рощам на севере Лиса. Среди деревьев редко встречались одинаковые; большинство находилось на разных стадиях одичания, а некоторые в течение долгих веков успели окончательно вернуться к первичным формам, заданным природой.

Родина многих деревьев была явно не на Земле - и даже, вероятно, не в Солнечной системе. Великаны-секвойи, достигавшие в высоту ста и более метров, словно часовые, возвышались над прочими деревьями. Некогда их принято было считать самыми древними жителями Земли: ведь они были старше Человека. Русло реки стало шире; по мере продвижения вниз по течению она все чаще разливалась озерцами, среди которых, словно на якоре, стояли крошечные островки.

Prospects of Investigation and Production of Waterborne Paintwork Materials

У нас впереди, на мой взгляд, несколько очень и очень интересных столетий. Джизирак долго сидел недвижимо, совершенно забыв о своей математике, после того, как изображение Хедрона растаяло.

Его терзало дурное предчувствие, не сравнимое ни с чем, что он когда-либо испытывал. В какой-то момент он даже задался вопросом -- а не следует ли ему попросить аудиенции у Совета?.

Он подумал о Джизираке, своем наставнике, который был так терпелив с ним, своим, должно быть, самым трудным учеником. Он припомнил се самые малейшие знаки доброты, которые проявляли по отношению к нему его родители все эти годы.

Им представилась картина, обратная тому, что наблюдал Олвин из центра Парка. Теперь он уже сверху вниз смотрел на концентрические волны камня и металла, многомильными дугами уходящие к центру города, Далеко-далеко, за силуэтами башен виднелись лужайки, деревья и Река с ее вечным круговым течением. А еще дальше -- к небу снова начинали карабкаться бастионы Стоя рядом с Олвином, Алистра тоже глядела на открывшийся вид -- глядела с удовольствием, однако без малейшего удивления.

Ей и прежде приходилось бессчетное число раз видеть свой город с почти столь же высоких точек, разве,что только в обстановке куда --более комфортабельной. -- Вот он, наш мир, -- весь, целиком, -- проговорил Олвин. -- А теперь я хочу показать тебе кое-что. Он повернулся спиной к решетке и двинулся навстречу далекому светлому пятнышку на противоположном конце туннеля.

Ветер холодил его едва прикрытое тело, но Олвин не замечал этого и с каждым шагом все дальше и дальше погружался в струи встречного потока воздуха. Он прошагал всего ничего, ногда до него вдруг дошло, что Алистра так и не двинулась с места.

Она стояла и смотрела на .

Ранее этого никогда не делалось: все твои предшественники остались. Этот выбор был неприемлем для Элвина. Он хотел изучить Лис, узнать все его тайны, выяснить, чем он отличается от его родины, но не менее решительно он был настроен вернуться в Диаспар, чтобы доказать друзьям, небеспочвенность своих мечтаний. Он не понимал причин этой тяги к секретности, но даже поняв их, он бы не изменил своего поведения. Он сообразил, что должен выиграть время или как-нибудь убедить Серанис, что невыполнимости ее требований.

- Хедрон знает, где я, - сказал. - Вы не можете стереть и его память. Серанис улыбнулась. Улыбка была приятной и при любых иных обстоятельствах вполне дружелюбной.

Туда же, в схемы памяти, поступили основные черты всех живших тогда людей, чтобы сделать возможным их возрождение в момент, когда некий импульс вновь призовет их к жизни.

До Элвина дошло, что в каком-то смысле он также должен был существовать в этом древнем мире. Конечно, не исключалось, что он был полностью синтезирован, что вся его личность была задумана художниками и техниками, работавшими с помощью невообразимо сложных инструментов над какой-то вполне ясной им целью.

Но Элвину казалось более вероятным, что он составлен из людей, некогда в самом деле ходивших по Земле. При создании нового города от старого Диаспара сохранилось очень мало; парк стер его почти целиком.

Даже до превращения в центре Диаспара была небольшая покрытая травой поляна, окружавшая узловой пункт, к которому сходились все радиальные магистрали. Позднее она расширилась вдесятеро, сметая улицы и дома. К этому времени на свет появилась и Гробница Ярлана Зея, заменив собой очень крупное округлое сооружение, стоявшее в точке схождения всех улиц. Элвин никогда не верил всерьез легендам о древности Гробницы, но, очевидно, легенды эти соответствовали правде.

Последние пять слов были напечатаны прописными буквами, и суть этого послания сразу же была схвачена Олвином. Произнесенные в уме, кодовые фразы такого рода столетиями использовались для того, чтобы открывать двери или включать машины.

Саги, в сущности, никуда не вели, - подумал. Они всегда замыкались в узких рамках. В них отсутствовали широкие перспективы, просторные ландшафты, по которым тосковала его душа.

Хилвар твердо взглянул на. - Не было нужды спрашивать об этом, Элвин, - ответил .

Увлекая Джизирака по коридору, он не мог не увидеть аналогии и делал поощряющие замечания по мере того, как его наставник, одну за другой переставлял не повинующиеся ему ноги, помаленьку все-таки продвигаясь. В отличие от Хедрона Джизирак не был трусом. Он был готов бороться со своим предубеждением, но это была борьба отчаяния.
