Abstract:
L'effet pro-oxydant des additifs surbasés peut être atténué ou même supprimé par incorporation dans l'additif surbasé d'un carboxylate de cuivre, issu d'acides carboxyliques aliphatiques à chaîne linéaire ou ramifiée en C₇ à C₁₀ . Ces carboxylates de cuivre peuvent également être utilisés sous forme d'association avec un dérivé du bore.
Abstract:
The present invention is, in one form, an aqueous alkaline metalworking fluid composition in the form of a concentrate which includes a salt of orthophosphoric acid; a dibasicdioic acid in an amount of up to about 5.0% by weight of the concentrate; an essentially phosphonate-free chelating agent; and, a neutralizing base. The composition may also include a lubricating agent, a coupling agent, a passavating agent, a biocide, and a colorant.
Abstract:
Des produits fonctionnels aqueux tels que des produits de nettoyage à usage domestique ou commercial, des produits domestiques, des produits utilisés dans le commerce, et des produits de toilette sont épaissis ou leur viscosité est modifiée par addition d'au moins un hydroxyde de métal mélangé cristallin de formule LimDdT(OH)(m+2d+3+na)Aan.xH2O, dans laquelle m est égal à une valeur comprise entre zéro et un, D est un métal bivalent, d est compris entre zéro et 4, T est un métal trivalent, A est au moins un anion ou un radical de valence négative de valence n, n vaut 1 ou plus, (m+2d+3+na) est égal ou supérieur à 3, (m+d) est supérieur à zéro, et xH2O est de l'eau d'hydratation.
Abstract:
Crystalline aluminates of the formula: I. (LiA x ) y ·2Al(OH)₃·nH₂O wherein A is one or more anions and/or negative-valence radicals or mixtures thereof; wherein, in formula I, x is a quantity of A ions or radicals sufficient to substantially satisfy the valence requirements of Li; wherein n is zero or the number of waters of hydration; wherein y is a numerical value at least sufficient to maintain the crystalline structure; are found to improve the properties of organic materials when incorporated therein.
Abstract:
A wire rod is payed out from a pay-off stand and descaled in a descaling process. After preheating to a predetermined temperature by a preheating device, it is subjected to a lubrication pretreatment through a zinc calcium phosphate solution applied with ultrasonic wave in the lubrication pretreatment process. After rinsing process, the lubrication-pretreated wire rod is coated with a calcium stearate or a sodium stearate in lubricating process. Thereafter, the wire rod is dried sufficiently in drying process, and then added with a predies lubricant in wire drawing process and coiled by a coiler.
Abstract:
Increased viscosity oil compositions have been prepared which comprise an oil and an inorganic complexing agent, said complexing agent being insoluble in oil and forming a viscosity increasing complex with the oil and a method for producing same.
