摘要： Amorphous precipitated silica is characterized by a standard white area of less than 0.8 percent. The low standard white area is a characteristic of the silica which is indicative of high (i.e., very effective) dispersion when the silica is incorporated into organic rubber compositions which are cured.Cured organic rubber compositions comprising amorphous precipitated silica exhibit low white areas which indicate high dispersion of the silica in the compositions.
摘要翻译： 无定形沉淀二氧化硅的特征在于标准白色面积小于0.8％。 低标准白色区域是二氧化硅的特征，当将二氧化硅掺入固化的有机橡胶组合物中时，其表现出高的（即非常有效的）分散体。 包含无定形沉淀二氧化硅的固化有机橡胶组合物表现出低的白色区域，这表明二氧化硅在组合物中的高分散性。

摘要： Corrosion inhibiting calcium-containing amorphous precipitated silica is described. The silica is prepared by admixing simultaneously in a reactor aqueous alkali metal silicate, e.g., sodium silicate, acidifying agent, e.g., hydrochloric acid, and a water-soluble source of calcium, e.g., calcium chloride. The product contains from 6 to 9 weight percent calcium (as CaO). The silica product may be incorporated into a coating composition used for corrodible metallic surfaces.

摘要： A rotor is provided for use in combination with a stator and sleeve to function as a valve attached to an actuator. The rotor is comprised of a rotor body containing the drive section with the necessary elements to turn the rotor within the stator and sleeve, and a rotor stem with parts to act with complementary parts on the sleeve to form variable orifices that function as the valve. The rotor body is connected to the rotor stem by a flexible joint which includes a contoured surface to compensate for misalignments in the system.

摘要： Finely divided, fluosilicate-treated silica, such as silica flatting agent for use in coating formulations, is prepared by blending in a dry, finely divided state, silica and divalent metal fluosilicate, notably magnesium fluosilicate. In a preferred embodiment, dry pellets of amorphous, precipitated silica and dry magnesium fluosilicate are milled together to produce the fluosilicate-treated flatting agent. In another embodiment, an aqueous solution of magnesium fluosilicate is applied to silica pellets which are then milled.
