Problems solved by technology

However, as a foamed linear polymer resin ball, it has a micro-cellular surface. When this type of floating bed white ball encounters organic matter, such as grease, engine oil, methanol, ethanol, acetone, ethyl acetate, etc., the surface of the ball will be eroded. It will even be gradually broken and disintegrated; another main technical problem existing in the existing floating bed white ball is that the surface of the ball will become soft and sticky in the water treatment environment with high temperature. The gas in the voids inside the foamed linear polystyrene sphere foams and expands, and then tends to become soft, sticky, and even stick together into blocks, which will cause the water cap to be blocked and affect the normal operation of the ion exchanger

Abstract

The invention provides a method for preparing surface cross-linked floating bed white sphere resin. The method comprises the following steps of: performing secondary polymerization of a surface on styrene and divinyl benzene on floating bed white spheres serving as base spheres, extending to the surface to form a cross-linked structure, and stabilizing the structure through each subsequent heating process. The obtained lightweight polymer white spheres have hard surfaces, have obvious technical effects on temperature resistance and organic substance and organic solvent resistance, and improve the performance and the stability of the water treatment floating bed white sphere resin; and the preparation method has the technical advantages of simplicity, feasibility and low energy consumption.

Description

Background technique [0001] What the patent application of the present invention relates to is the preparation method of polystyrene sphere. Background technique [0002] Floating bed white ball resin is a low-density inert covering layer resin, which is mainly used in floating bed ion exchangers in industrial water treatment systems to prevent fine particle ion exchange resins from clogging the water cap or being carried away by water flow, and improve The effect of the uniformity of water flow and regeneration fluid distribution. This floating bed white ball resin is mainly produced by the conventional preparation method of micro-foaming polystyrene, such as Chinese patent technology: Patent No. 200910011586.0 discloses a "preparation method of uniform density floating bed white ball resin". However, as a foamed linear polymer resin ball, it has a micro-cellular surface. When this type of floating bed white ball encounters organic matter, such as grease, engine oil, metha...
