Problems solved by technology

After the scale is generated, the heat exchange efficiency of the equipment will decrease. According to statistics, in some precision water systems, when the scale is as thick as 0.1mm, the thermal efficiency will drop by about 5%. Therefore, the generation of scale will directly affect the normal use of the equipment. Therefore, people use Many ways to remove limescale
Manual descaling is also one of the methods, but manual removal is powerless for some equipment with complex shapes
The general chemical cleaning method uses common chemical cleaning agents to remove scale, but the operation is more complicated, professional knowledge is required, and the equipment is severely corroded.
Many thin-walled equipment generally cannot be used, so it is necessary to research and develop precision water system descaling agents that meet the needs

Abstract

The invention discloses a precise water system descaling agent, which comprises the following components in percentage by weight: 13.3 to 16.8 percent of nicotinic acid, 8.0 to 10.3 percent of glacialacetic acid, 6.6 to 9.1 percent of ammonium bifluoride, 1.8 to 2.8 percent of sodium gluconate and the balance of water. The precise water system descaling agent does not corrode equipment, is odorless, high in descaling rate and high in descaling speed, and does not corrode a human body.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and in particular relates to a precision water system descaling agent and a preparation method thereof. Background technique [0002] Our daily life is inseparable from water. Many factories, restaurants, and hotels also need water for some equipment. For example, various types of precision water systems such as heat exchangers, cooling towers, air conditioners, and condensers are commonly used in operation and use for a period of time. Finally, due to the thermal deposition and adsorption of impurities and microorganisms in the water on the heat exchange surface, these deposits are called scale. The composition of scale is complex, usually composed of chemical compounds, algae and sediment. After the scale is generated, the heat exchange efficiency of the equipment will decrease. According to statistics, in some precision water systems, when the scale is as thick as 0.1mm, the thermal e...
