Problems solved by technology
Scale inhibitors are combined with calcium and magnesium ions in water through complexation or chelation chemical forms, so that when the saturation solubility is reached, the formed scale crystals undergo lattice distortion, and the formed scale is relatively loose. The form is deposited in the system reservoir; the combination degree of the antiscalant and calcium and magnesium ions in the water is called the scale inhibition rate, and its size determines the amount of hard scale that cannot be deformed in the l

Abstract
The invention discloses an on-line scale prevention and removal agent for circulating water, belongs to the technical field of scale removal agents, and effectively solves the problem that an existing circulating water system cannot be integrally cleaned in the production and operation process. Comprising the following raw materials in parts by weight: 30-50 parts of polydiamino-terminated sodium acrylate, 10-30 parts of deionized water, 1-2 parts of an imidazoline surfactant, 1-2 parts of a pH regulator, 1-5 parts of a corrosion inhibitor, 1-5 parts of a chelating agent, 5-10 parts of a dissolving agent and 5-10 parts of a cosolvent. The prepared polydiamino-terminated sodium acrylate is used as a main raw material, descaling operation of a circulating water system can be carried out under the condition that normal operation of the system is not affected, the descaling effect is good, the efficiency is high, meanwhile, by adding the imidazoline type surfactant, the corrosion inhibitor, the chelating agent and the cosolvent, the descaling effect is good, and the descaling effect is good. The scale remover is simple in structure and convenient to use, can effectively prevent calcium and magnesium ions from reacting to form precipitates in the descaling process, avoids the phenomenon that dirt blocks a pipe, is low in cost, and has good economic benefits and wide market prospects.
Description
technical field [0001] The invention belongs to the technical field of descaling agents, and in particular relates to an online anti-scaling and descaling agent for circulating water. Background technique [0002] Any production device is inseparable from the circulating water system. Domestic and foreign circulating water systems involve all production industries and are mainly divided into two categories: industrial circulating water systems and municipal central heating and heating circulating water systems. At present, to deal with the three major problems of scale formation, corrosion, and microbial sticky sludge in the circulating water system, technologies are adopted to reduce the speed of scaling, corrosion, and microbial growth. Such technologies cannot solve the accumulation of dirt and the decreasing heat transfer efficiency. The clean running state of the circulating water system cannot be maintained, and the dirt that has formed cannot be removed online without...
