Problems solved by technology

Due to the lack of sense of responsibility of managers and operators, many circulating water systems cannot sterilize in time, so it is very easy to cause a sudden proliferation of microorganisms and form microbial slime
Under the above circumstances, relying on conventional oxidizing fungicides and non-oxidizing fungicides for sterilization can no longer achieve the desired effect on slime removal

Embodiment 1

[0015] How to use: According to the amount of water retained in the circulating water system, it is directly added to the circulating pool according to a certain dosage, and circulates in the system for a certain period of time through the circulating water pump. After the slime falls off completely, it can be drained and replaced.

[0016] Embodiment two

Embodiment 2

[0018] How to use: According to the amount of water retained in the circulating water system, it is directly added to the circulating pool according to a certain dosage, and circulates in the system for a certain period of time through the circulating water pump. After the slime falls off completely, it can be drained and replaced.

[0019] Embodiment Three

Embodiment 3

[0021] How to use: According to the amount of water retained in the circulating water system, it is directly added to the circulating pool according to a certain dosage, and circulates in the system for a certain period of time through the circulating water pump. After the slime falls off completely, it can be drained and replaced. Embodiment Four

[0022] First, add a certain amount of 60g deionized water into the reactor with stirring device, and start to heat up. When the water temperature reaches 40°C, turn on the stirring device and start stirring, and then add 15g of glutaraldehyde and 25g of dodecylbenzyl ammonium bromide After 10 minutes, add 6g of PAAS and continue to stir for 10-15 minutes, then add 10g of alkanolamide and stir for 15 minutes, then let it stand still for 2 hours.

Abstract

The invention provides an inoxidable sludge stripping agent and a preparation method thereof. The inoxidable sludge stripping agent is composed of an organic inoxidable biocide, a surfactant, a dispersing agent and water, wherein the mass ratio of the organic inoxidable biocide to the surfactant to the dispersing agent to the water is (10-30) to (5-15) to (1-10) to (40-60). The invention also provides the preparation method of the inoxidable sludge stripping agent. The preparation method comprises the steps of sequentially adding the organic inoxidable biocide, the surfactant, the dispersing agent and the water into a reactor with a stirring device according to the mass part, and stirring to dissolve all the components to obtain the inoxidable sludge stripping agent. The inoxidable sludge stripping agent provided by the invention is an efficient liquid agent and can be used when a circulating cooling water system is polluted by sludge. The inoxidable sludge stripping agent provided by the invention has a favorable function for stripping and removing sludge and dead microorganisms attached on the inner walls of equipment and pipelines, can also be used for killing various microorganisms such as bacteria and fungi in a circulating water system and can be widely applied to the field of circulating cooling water treatment.

Description

technical field [0001] The invention relates to the field of circulating cooling water treatment, in particular to a circulating cooling water treatment agent, in particular to a non-oxidative slime stripping agent and a preparation method thereof. Background technique [0002] With the process of industrialization in our country, more and more industrial production needs to apply circulating cooling water system, and the good operation of circulating cooling water system plays a vital role in safe production. However, due to the risks of corrosion, scaling, and slime pollution during the operation of circulating water, once it occurs, it will not only reduce the service life of the equipment, but also bring safety hazards to production, and even cause production stoppage, which greatly affects the economic benefits of the enterprise. Among all kinds of pollution, slime pollution caused by microbial reproduction is the most likely to occur and has a greater impact. [0003]...
