Abstract

The invention provides a composition for removing scale. The composition comprises the following ingredients by weight: 2 to 50 percent of aminosulfonic acid (NH2SO3H), 1 to 10 percent of sodium tripolyphosphate (STPP) and 0.5 to 5 per thousand of penetrating agent (JFC). The invention also provides a preparation method and applications of the composition. The composition has fast reaction velocity for removing scale, little corrosion to the material and high scale-removing rate.

Description

technical field [0001] The invention relates to a scale removal composition, in particular to a scale removal composition and a preparation method and application thereof. Background technique [0002] The water quality in the Yellow River Basin in my country is poor. Short-term use will easily generate scale inside water heaters, car water tanks and other containers, affecting the 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 performance of metal, the thermal conductivity of scale is dozens or even hundreds of times higher than the former. 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 the engine at an appropriate tempe...
