Abstract

The invention relates to the technical field of scale-inhibiting functional materials, in particular to an efficient scale-inhibiting material and a production method and application thereof. The efficient scale-inhibiting material comprises a support and aluminum-iron alloy loaded onto the surface of the support; the support comprises the following components in percentage by weight: 99.0%-99.6%of sodium polyacrylate and 0.4%-1.0% of ceramics; and the average molecular weight of the sodium polyacrylate is 500-2000. The production method comprises the following steps of (1) producing crystalsof the sodium polyacrylate, and coating the surface of the crystals of the sodium polyacrylate with the ceramics; and (2) depositing the aluminum-iron alloy on the crystals, coated with the ceramics,of the sodium polyacrylate. The efficient scale-inhibiting material can be used in a pressure container, no additives or emissions exist in the whole process, water pollution is avoided, and food-grade standard is achieved.

Description

technical field [0001] The invention relates to the technical field of scale-inhibiting functional materials, in particular to a high-efficiency scale-inhibiting material and its preparation method and application. Background technique [0002] Limescale is a pervasive problem that makes thermal conductivity poor. When the heat exchange surface is scaled, it will not only cause serious energy waste, but also easily lead to local corrosion or even perforation of various water appliances and water equipment, and more serious cases will cause explosions due to uneven heating. [0003] The analysis of the chemical composition of the scale shows that the scale is mainly composed of insoluble salts, among which the insoluble calcium salt is the main one, and calcium carbonate is the most widely existing insoluble calcium salt in the scale. [0004] However, the traditional antiscaling method usually adopts chemical complexation, which is low in efficiency and high in cost in indu...
