Description
Применение консистентных смазок , содержащих в качестве антикоррозийной присадки бензоат натри , ограничено, так как водные растворы бензоата натри , представл ющие собой соли слабой кислоты и сильного основани , имеют сильно щелочную реакцию и вызывают коррозию изделий из цинка, алюмини , меди и др. металлов.The use of greases containing sodium benzoate as an anticorrosive additive is limited because aqueous solutions of sodium benzoate, which are salts of a weak acid and a strong base, are highly alkaline and corrosive to products made from zinc, aluminum, copper and other metals.
Предлагаемое изобретение позвол ет устранить корродирующее действие бензоата натри путем введени в смазки смеси бензоата натри и бензойной кислоты, имеющей рН 7, в количестве не менее 0,2%. Предложенна присадка оказывает защитное антикоррозионноеThe present invention eliminates the corrosive effect of sodium benzoate by introducing into the lubricant a mixture of sodium benzoate and benzoic acid having a pH of 7 in an amount of at least 0.2%. The proposed additive has a protective anti-corrosion.
действие как на черные, так и на цветные металлы.action on both ferrous and non-ferrous metals.
