Abstract

The invention relates to an anti-scaling agent for air conditioner circulating water. The anti-scaling agent for the air conditioner circulating water is characterized by being prepared from components in parts by mass as follows: 30-60 parts of sulfamic acid, 15-35 parts of citric acid, 15-35 parts of oxalic acid and 10-25 parts of sodium hexametaphosphate. The product is solid and thus is very convenient to store and transport. The sulfamic acid in the scheme causes smaller corrosion to metal, the hydrogen embrittlement phenomenon cannot be produced, citric acid and oxalic acid in the schemehave very high dissolution capacity, and the scheme has high anti-scaling capacity and wide application range.

Description

technical field [0001] The invention relates to the technical field of chemical product production, in particular to a descaling agent for air-conditioning circulating water. Background technique [0002] A descaling agent is a chemical agent that removes scale, dirt and other scale stains. It is generally composed of multiple components. Industrial descaling agents are mainly used to remove dirt in heat exchange equipment, boilers, etc., and household descaling agents are mainly used to remove dirt in water dispensers. At present, the industrial descaling agents on the market have the following problems: 1. The cost is high and the process is complicated. 2. The descaling agent itself will cause secondary pollution. Therefore, a new solution is urgently needed to solve this technical problem. SUMMARY OF THE INVENTION [0003] The present invention provides a descaling agent for air-conditioning circulating water precisely aiming at the technical problems existing in the ...
