Abstract

The invention provides an organic descaling composition, which includes an organic cleaning agent and a corrosion inhibitor CM-911, and the weight ratio of the organic cleaning agent and the corrosioninhibitor is 100:0.1-0.3. The organic cleaning agent includes the follow components by weight: 1%-15% of maleic acid-crylic acid copolymer (MA-AA), 1%-25% of 1-hydroxyethylidene-1,1-diphosphonic acid(HEDP), 2%-30% of amino trimethylene phosphonic acid (ATMP), 0.03%-0.5% of penetrating agent JFC and balance of water. The organic descaling agent provided by the present invention has advantages offast reaction speed, small corrosivity for material and high descaling efficiency.

Description

Technical field [0001] The invention relates to a descaling composition, in particular to an organic descaling composition and its application. Background technique [0002] The water quality of the Yellow River basin in my country is poor. Short-term use will easily cause scale in the water heaters, automobile water tanks and other containers whose temperature can reach 30℃ or higher, which will affect the heat transfer performance of these equipment. When the scale thickness of the water heater reaches 2mm thick, the energy waste caused is about 25%. Compared with the thermal conductivity of metal, the thermal conductivity of metal is dozens or even hundreds of times higher than that of scale. . In areas with poor water quality, it takes only 2-3 months to form scale with a thickness of 2mm. Whether the water heater is used for a few months of scale removal will vary greatly in terms of energy consumption. The working effect of the car water tank is to dissipate heat and main...
