    • The present invention relates to a monocarboxylic acid based antifreeze coolant formulation for applications such as for gasoline engines which may be used for inhibition and prevention erosion and corrosion of aluminum and the corrosion of other metals exposed to an aqueous liquid in automotive coolant systems. The formulation further inhibits mineral scale. It may be packaged as an ethylene glycol based additive for use in new engines or in a concentrated inhibition package as an additive as for reinhibition of used coolant. The combination of a mixture of ethylene or propylene glycol, a monobasic carboxylic organic acid, azoles, and low levels of molybdates provides corrosion resistance. A heavy duty formula more suited for diesel engines also contains a nitrite salt and/or nitrate salt and a siloxane stabilized silicate, and combinations thereof to provide a synergistic protective effect against the cavitation corrosion of aluminum in aqueous liquids reducing the corrosion rate and is effective at relatively low concentrations varying pH ranges.
    • 本发明涉及一种用于汽油发动机的应用的基于单羧酸的防冻剂制冷剂制剂,其可用于抑制和防止铝的侵蚀和腐蚀以及暴露于汽车冷却剂系统中的含水液体的其它金属的腐蚀。 该制剂进一步抑制矿物垢。 它可以作为用于新发动机的乙二醇基添加剂或作为添加剂的浓缩抑制包装被包装,用于重新抑制用过的冷却剂。 乙烯或丙二醇,一元羧酸有机酸,唑类和低含量钼酸盐的混合物的组合提供耐腐蚀性。 更适用于柴油发动机的重型配方还含有亚硝酸盐和/或硝酸盐和硅氧烷稳定的硅酸盐及其组合,以提供抗水溶液中铝的气穴腐蚀的协同保护作用,降低腐蚀速率,并且是有效的 在相对较低的浓度变化pH范围。

    • A hydrophobic self cleaning coating composition that can be applied by conventional methods such as by spraying the composition onto a surface forming creating a wet and dry dirt repellent coating on the surface. The coating utilizes hydrophobic nanoparticles of fumed silica and/or titania in a solvent which evaporates at ambient temperature. The coating solves the problem of poor resistance to UV light, opaque appearance, and/or abrasion found in previous coatings of similar nature. Virtually transparent coating are produced as compared to conventional coatings of comparable hydrophobicity which are typically white or opaque. The coating can be applied by a single and easy spraying method and the super hydrophobic property can be achieved by drying the film by evaporation of the solvent at ambient temperature for 5 to 10 minutes. Embodiments of the hydrophobic self-cleaning coating composition can be produced resulting in a clear coating or in some cases a translucent dirt repellant film or coating on painted material, plastic, metal, glass, ceramic, fiberglass or a polymer substrate. One preferred coating composition utilizing an effective amount of a treated fumed silica in a solvent forms a coated surface providing a contact angle of at least 165 degrees as compared to water having a contact angle of from 10 to 15 degrees on a noncoated surface. The self-cleaning coating composition imparts a degree of hydrophobicity to a surface so that the treated surface will have a tilt angle of sliding of less than 2 degrees as compared to water on a noncoated surface having a tilt angle of sliding of 90 degrees or higher.
    • 疏水性自清洁涂料组合物,其可以通过常规方法施用,例如通过将组合物喷涂到表面上形成湿表面和干污垢涂层的表面上。 该涂层使用在环境温度下蒸发的溶剂中的热解法二氧化硅和/或二氧化钛的疏水性纳米颗粒。 该涂层解决了在类似性质的先前涂层中发现的耐紫外线性差,不透明外观和/或耐磨性差的问题。 与通常为白色或不透明的相当的疏水性的常规涂层相比,产生几乎透明的涂层。 可以通过单一且容易的喷涂方法施加涂层,并且可以通过在环境温度下蒸发溶剂5至10分钟来干燥膜来实现超疏水性。 可以制造疏水性自清洁涂料组合物的实施方案,从而形成透明涂层,或在某些情况下产生在涂漆材料,塑料,金属,玻璃,陶瓷,玻璃纤维或聚合物基材上的半透明防污膜或涂层。 使用有效量的经处理的热解法二氧化硅在溶剂中的一种优选的涂料组合物与在非涂层表面上的接触角为10至15度的水相比形成了涂覆表面,其提供至少165度的接触角。 自清洁涂料组合物赋予表面一定程度的疏水性,使得与具有90度或更高的滑动倾斜角的未涂覆表面上的水相比,经处理的表面将具有小于2度的倾斜倾斜角度 。
