Abstract

The invention relates to a making method for physical anti-scaling nanocoposite ceramic ball particles. The making method is simple and low in cost, and the nanocomposite ceramic ball particles made through the method should be able to effectively prevent water scales from being generated, and effectively remove the water scales. According to the technical scheme, the making method for the physical anti-scaling nanocomposite ceramic ball particles includes the following steps that step1, by weight, the following materials of 20-85 parts of tourmaline, 10-40 parts of kaolin, 1-8 parts of light rare earth and 3-27 parts of copper zinc alloys are prepared; step2, the materials are machined to be powder of which the particle size ranges from 100 nm to 900 nm; step3, the powder is evenly mixed to make ball particles of which the particle size ranges from 2 mm to 5 mm; step4, the ball particles are sintered for 0.1-5 hours at the temperature of 700 DEG C-1100 DEG C, and then kept warm for 4-24 hours at the temperature of 45 DEG C-100 DEG C.

Description

Technical field [0001] The invention belongs to the physical method anti-fouling technology, and is specifically a preparation method of nanocomposite ceramic pellets. Background technique [0002] When water is used as a heat exchange medium, a difficult obstacle to overcome is scaling. The texture of scale is relatively dense and the thermal conductivity is low, which greatly reduces the heat transfer efficiency (according to experimental studies, a thin scale of 0.6 mm can reduce the heat transfer efficiency). reduced by more than 20%). [0003] In recent years, anti-scaling technology and de-scaling technology have made great progress, but scale is still impossible to prevent and eliminate. Nowadays, the commonly used anti-scaling and descaling methods in engineering include: softened water method, ultrasonic water treatment method, and chemical dosing method. [0004] (1) Softened water method: This water treatment method removes most of the calcium and magnesium ions...
