Fuel additives and fireside chemicals are a formulation of combustion alysts, dispersants, oxidising agents, propellants and oxidisers in balanced quantities that helps in ensuring proper combustion, reduction in clinker formation, increase in heat transfer and reduction in .
Keywords: wear, additive Valena, tin, spheroidal graphite, cast iron. 1. INTRODUCTION The spheroidal graphite cast iron is a high strength construction material with a complex of properties which make it different from the conventional FeC alloys, namely high tensile strength, high plasticity and wear resistance,
Dec 03, 2020 · The composition contains anticorrosion additives, working pointwise. G12 ++: Most often purple, an improved version of carboxylated coolants. Lobride antifreeze differs from G12 and G12 + in the presence of silie additives, thanks to which the anticorrosion properties work pointwise and prevent the formation of rust. Antifreeze G13
E numbers ("E" stands for "Europe") are codes for substances used as food additives, including those found naturally in many foods such as vitamin C, for use within the European Union (EU): 27 and European Free Trade Association (EFTA). Commonly found on food labels, their safety assessment and approval are the responsibility of the European Food Safety Authority (EFSA).
An additive for increasing the toughness of thinwall iron castings is provided. The additive includes amounts of a nonferrous metal oxide and a metal sulfide in which the nonferrous metal has an affinity for oxygen less than that of iron, and the metal has an affinity for sulfur less than that of magnesium. The metals contained in the oxides and sulfides are also not alkali, alkali .
