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 corrosion inhibitor 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 of fast 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 in the Yellow River Basin in my country is poor, and short-term use will easily generate scale inside water heaters, car water tanks and other containers with temperatures above 30°C, affecting the heat transfer performance of these devices. When the scale thickness of the water heater reaches 2mm, the energy waste caused is about 25%. Compared with the thermal conductivity of metal, the thermal conductivity of metal is dozens of times or even hundreds of times higher than that of scale. . In areas with poor water quality, it only takes 2-3 months to form scale with a thickness of 2 mm. After several months of use, whether to remove scale will make a big difference in energy consumption. The working effect of the car water tank is to dissipate heat and maintain the normal operation of...
