Abstract

The invention discloses an extraction tank. The extraction tank is prepared from the following components in parts by weight: 15-20 parts of novolac vinyl ester resin compositions, 5-10 parts of methylated benzoguanamine resin, 1-5 parts of polyurethane, 5-10 parts of nano-organic-silica, 5-10 of nano-silica, 80-100 parts of quartz sand, 5-10 parts of glass fiber and 1-2 parts of a curing agent. The extraction tank can meet the load requirements of carrying extraction liquid, a mixer and the like. The novolac vinyl ester resin compositions are high in acid and alkali corrosion resistance and impact resistance and high in thermal stress, and cracking of a tank body due to thermal stress in the curing process is avoided. The surface of the nano-organic-silica has a large number of hydroxyl groups and silicon-oxygen bonds, the addition of the hydroxyl groups and the silicon-oxygen bonds can greatly enhance the reaction and compactness between the resin composition and the inorganic quartzsand and glass fiber, and the overall firmness and heat stress of the extraction tank are improved. The glass fiber is dispersed in a skeleton of the entire extraction tank, and is insulated and heat-resistant, and the mechanical strength of the extraction tank is improved.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to an extraction tank and a preparation method thereof. Background technique [0002] In the production process, it is often necessary to effectively separate and purify the mixture of two or more phases. The extraction tank used to complete the extraction work is usually composed of a mixing chamber and a clarification chamber, which belongs to the step-by-step contact liquid-liquid mass transfer equipment. The mixing chamber is equipped with an agitator to facilitate droplet breakup and homogeneous mixing. The clarification chamber is an empty chamber with a large cavity volume, which is used for static stratification of the mixed liquid. According to the separation requirements, the extraction tank can be used in a single stage, or in combination with multi-stage series countercurrent. During the extraction process, the mixing of liquids will cause a great impact on the extra...
