Chemistry and Technology of Lubricants

Lubricating oils used in machines with an open cutting system, such as a saw or harvester, are applied in forest areas, gardening, in the household, and in urban greenery. During the operation of the device with an open cutting system, the lubricating oil is emitted into the environment. Therefore, the use of an oil base and refining additives of petroleum origin in the content of lubricants is associated with a negative impact on health and the environment. The current legal regulations concerning lubricants applicable in the European Union EU assess the degree of biodegradability. The paper aims to draw public attention to the need to reduce the toxicity and harmful effects, due to their composition, of lubricating oils emitted into the environment on health. The authors discuss the impact of petroleum oil lubricants on soils, groundwater, vegetation, and animals, and the impact of petroleum-origin oil mist on health. An overview of test methods for the biodegradability of lubricating oils is presented, including the Organization for Economic Cooperation and Development OECD A—F, , and A—D tests, as well as their standard equivalents.

The chemicals and other components produced by Chevron Phillips Chemical and its affiliates are more than just molecules. They are essential to the manufacture of more than 70, consumer and industrial products. Our products are used to make food packaging, cleaner fuels, biodegradable solvents, and much more. Lubricant additives made by Chevron Oronite are blended into refined base oils to dissolve deposits, inhibit corrosion, control oxidation and reduce friction. Chevron Oronite develops, manufactures and markets performance-enhancing additives for lubricating oils and fuels. Oronite products combine innovative technology and the latest research to help maximize the reliability, efficiency and life of engines. The result is fewer emissions and less impact on the environment.

Examines the chemistry of lubricating oil additives, including antioxidants, lubricity and extreme-pressure additives, pour-point depressants, viscosity-index improvers, and rust inhibitors.

A lubricant is a substance, usually organic , introduced to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces. The property of reducing friction is known as lubricity. In addition to industrial applications, lubricants are used for many other purposes. Other uses include cooking oils and fats in use in frying pans , in baking to prevent food sticking , bioapplications on humans e. It is mainly used to reduce friction and to contribute to a better and efficient functioning of a mechanism.

Уничтожение ТРАНСТЕКСТА. Уже несколько лет Танкадо пытался рассказать миру о ТРАНСТЕКСТЕ, но ему никто не хотел верить. Поэтому он решил уничтожить это чудовище в одиночку.

Быть может, в ТРАНСТЕКСТЕ какой-нибудь сбой и… - Все в полном порядке. - Но это значит, что пароль неимоверной длины. Стратмор пожал плечами: - Стандартный коммерческий алгоритм. Насколько я могу судить, пароль из шестидесяти четырех знаков.

 - Вы дежурили все это время. - Моя смена от семи до семи, - кивнула женщина. - Тогда вы наверняка ее видели.


 Полезный груз? - предложил Бринкерхофф.  - Количество жертв. Ущерб в долларах. - Нам нужна точная цифра, - напомнила Сьюзан.  - Оценки ущерба всюду приводятся разные.  - Она еще раз взглянула на текст.  - Элементы, ответственные… У Дэвида Беккера, находившегося в трех тысячах миль от комнаты оперативного управления, загорелись .

Техники обнимали друг друга, подбрасывая вверх длинные полосы распечаток. Бринкерхофф обнимал Мидж. Соши заливалась слезами. - Джабба, - спросил Фонтейн, - много они похитили. - Совсем мало, - сказал Джабба, посмотрев на монитор.  - Всего лишь какие-то обрывки, в полном виде - .

Base oil categories. Safety of petroleum base oils. Conventional base oil manufacturing methods. Historic methods.

 - Хейл вроде бы затрубил отбой.  - Теперь это не имеет значения. У вас есть ТРАНСТЕКСТ. У вас есть возможность мгновенно получать информацию. Вы можете читать все, что пожелаете, - без всяких вопросов и запросов.

Alternatives antioxidant lubricant additives have been proposed by many researchers to replace long-time use of multifunctional lubricant additive, Zinc-dialkyl-dithiophosphate ZDDP.
