Abstract

The invention belongs to the technical field of daily chemical products and particularly relates to a scale scavenging agent and a preparation method thereof. The scale scavenging agent provided by the invention comprises the following components in percentages by mass: 10-20% of modified starch, 10-20% of organic acid, 10-20% of a nonionic surfactant, 3-10% of an anionic surfactant, 3-5% of a metal corrosion inhibitor and 25-64% of water. The scale scavenging agent provided by the invention is fast in scale removal speed, high in scale removal rate and small in metal corrosion.

Description

technical field [0001] The invention belongs to the technical field of daily chemical products, and in particular relates to a scale remover and a preparation method thereof. Background technique [0002] Scale is generated inside containers such as water heaters, automobile water tanks, and thermos bottles, which affects the functions of these devices. When the structural thickness of the water heater reaches 2mm, the energy waste caused is about 25%. The thermal conductivity of scale is compared with that of metal. The latter It will be 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 temperature. When the inner wall of the water tank of t...
