Abstract:
本發明係關於一種線鋸切割流體組合物,其包含25至75重量%的懸浮於含聚合物黏度改質劑之含水載劑中之顆粒狀研磨劑,該聚合物黏度改質劑包含主要包括非離子性單體單元(較佳為100莫耳%之非離子性單體單元)之聚合物,具有至少5kDa的數量平均分子量(Mn),且係以足夠濃度存在於該組合物中,以使該組合物在25℃及60rpm的主軸旋轉速度下之布洛克菲爾德黏度(Brookfield viscosity)在50至1000cP的範圍內(例如50至700cP)。在一實施例中,該黏度改質劑包括一具有至少200kDa重量平均分子量(Mw)之聚合物。當利用200kDa或更大Mw之黏度改質劑時,一種較佳的線鋸切割方法為藉由在不大於10 4 s -1 之相對較低剪切速率下操作的泵及噴嘴循環及施用該切割流體。

Abstract:
A nanoparticle dispersion is taught for use as an additive to a lubricant. The dispersion comprises nanoparticles having a primary particle size less than 500 nm and having a Moh's hardness greater than 7 and a branched chain fatty acid dispersant that is pourable at a temperature of from -30°C to 320°C, wherein the dispersion is colloidally stable. A method of making a nanoparticle dispersion is further taught, for use as an additive to a lubricant. The method involves reducing the particle size of a material having a Moh's hardness of greater than 7, to nanoparticles having a primary particle size less than 500 nm, adding a branched chain fatty acid dispersant to the nanoparticles and forming a colloidally stable nanoparticle dispersion. Methods for using the present nanoparticle dispersion are also taught.
Abstract:
Methods and systems in which a shapable mass, which is processed according to the method or in the system, has a lubricant applied thereto. As it is processed in the system, the shapable mass having the lubricant applied thereto is used to transfer lubricant to a part or parts of the system.
Abstract:
Compositions having a plurality of hard particles and a plurality of lubricant nanoparticles are disclosed. Methods of making and using the compositions are also disclosed.
Abstract:
The present invention is devised to address the technical issues of decrease in lubrication under high speeds and occurrences of catalytic converter catalytic poisoning due to conventional molybdenum sulfide or extreme-pressure lubricants, or sulfur or phosphorus, the aim of the present invention being to increase the lubricating effect of engine oil used in CGN, LPG, gasoline, diesel, ship and airplane engines and to contribute to reductions in toxic discharge gas and fuel usage and an increase in combustion efficiency. To that end, disclosed are an engine oil additive and a method for producing same, the engine oil additive, by being used in gear oil and such, having the benefits of: reducing friction and extending the life span of the gear oil, which in turn reduces noise and vibration to increase the comfort of the passengers; and reducing the discharge of toxic gas and improving fuel cost, which allow the benefit of reducing greenhouse gases to be obtained at the same time from the reduced CO2, thus contributing significantly to improving the atmospheric environment by effective use of energy and reduction in carbon dioxide, a greenhouse gas.
