Embodiment approach

[0021] According to a preferred embodiment of the present invention, the water treatment chemical composition does not contain phosphorus, that is, the water treatment chemical composition does not contain conventional phosphorus-based corrosion inhibitors and / or phosphorus-based corrosion and scale inhibitors. In this preferred embodiment, the water treatment chemical composition can not only obtain better scale inhibition, corrosion inhibition and bactericidal effect, but also avoid the traditional water treatment chemical using a large amount of medicines containing phosphorus as scale and corrosion inhibitors. Defects that cause environmental pollution.

[0022]The present invention also provides the application of the above phosphorus-free water treatment agent composition in the water treatment process.

[0023] In the above application process, the water suitable for the treatment of the phosphorus-free water treatment composition can be various conventional industrial ...

Embodiment 1

[0062] This example is used to illustrate the phosphorus-free water treatment agent composition provided by the present invention.

[0063] Preparation of water treatment agent: at room temperature, 2.0g of zinc thiram was first dissolved in 5mL of ethanol, and then dissolved together with 19g of sodium tetraborate decahydrate and 13.4g of AA / AM / AMPS copolymer with a solid content of 30% by weight In deionized water, stir evenly, and prepare 100g of water treatment agent A1.

Embodiment 2

Abstract

The invention discloses a non-phosphorus water treatment agent composition. The composition contains a fukumi-series fungicide, a sulfonyl-containing non-phosphorus copolymer and a corrosion inhibitor, wherein the corrosion inhibitor is one or more of borate, gluconate and silicate. The invention also discloses an application of the non-phosphorus water treatment agent composition in water treatment. Results of evaluating the scale inhibition, corrosion inhibition and sterilization properties of the non-phosphorus water treatment agent composition applied to water treatment show that the non-phosphorus water treatment agent composition also has a high calcium carbonate scale inhibition rate, a high zinc scale inhibition rate, a high sterilization rate and a low carbon steel corrosion rate on the premise of not containing phosphorous water treatment agents. Therefore, a non-phosphorus water treatment agent in the invention has the advantages of environmental friendliness and good water treatment effect.

Description

technical field [0001] The invention relates to a phosphorus-free water treatment agent composition and the application of the composition in circulating cooling water treatment. Background technique [0002] In the circulating cooling water system, there are mainly three problems of scaling, corrosion and microbial hazards. The most convenient and effective way to prevent system scaling and corrosion is to add corrosion and scale inhibitors to the circulating cooling water. At present, the formulas commonly used in the treatment of circulating cooling water in China are mostly phosphine-based formulas, mainly containing phosphonic acid groups (—PO 3 h 2 ) Corrosion and scale inhibitors directly connected to carbon atoms, often called organic phosphonic acids. Compared with the inorganic polyphosphates in the early phosphorus-based formulations, organic phosphonic acid has the advantages of good chemical stability, not easy to hydrolyze, high temperature resistance, small...
