Multifunctional sustained-release agent for industrial circulating water system and preparation method thereof

Abstract

The invention discloses a multifunctional sustained-release agent for an industrial circulating water system and a preparation method thereof. The multifunctional sustained-release agent is composed of the following components in percentage by weight: 2-5% of zinc sulfate, 1-6% of sodium sulfite, 1-3% of sodium methyl silicate, 0.5-6% of ammonium salt, 10-15% of a pH value adjusting and complexingagent, 5-17% of an antirust agent, 17-32% of a scale inhibitor, 2-5% of a surfactant, 3-5% of a coagulant and 15-30% of an anti-freezing agent. The multifunctional slow-release agent prepared by theinvention can effectively remove scale and rust which are difficult to remove in an industrial circulating water system pipeline, and also can play a role in corrosion prevention on the pipeline; in addition, the anti-freezing effect is achieved, and an anti-freezing agent does not need to be additionally added when the pipeline is used in winter; and various effects can be achieved by one-time use, so that the labor intensity is reduced, and the production water is saved. The preparation method is simple, raw materials are simple and easy to obtain, and investment cost is low.

Description

technical field [0001] The invention belongs to the technical field of sustained-release agents, in particular to a multifunctional sustained-release agent for industrial circulating water systems and a preparation method thereof. Background technique [0002] In industrial production, a large amount of circulating cooling water is usually used. Generally, softened water is purchased for recycling. The long-term purchase cost is high, and the soft water will gradually harden after long-term use due to the contact between the pipeline and the circulation box. , Dirt will also remain, precipitate or form on the inner wall of the pipe. Once scaling occurs on the equipment, it will directly reduce the thermal conductivity, thereby wasting fuel, increasing fuel consumption, causing corrosion under the scale, shortening the service life of the equipment, and even causing safety accidents, leading to the risk of production shutdown. [0003] The traditional domestic slow-release a...

Problems solved by technology

Once the equipment is scaled, it will directly reduce the thermal conductivity, thereby wasting fuel, increasing fuel consumption, causing corrosion under the scale, shortening the service life of the equipment, and even causing safety accidents, resulting in the risk of production shutdown

[0003] The traditional domestic slow-release agent has a single function, which can only play a partial role, and the treatment effect is not ideal; it also seriously corrodes the equipment and pipelines, and also pollutes the environment

At present, the slow-release agents imported from abroad have better functions, but they are expensive, which increases the production cost of enterprises
