Problems solved by technology

[0002] In industrial production, galvanizing devices and equipment are very common. In the cleaning of industrial equipment, the problem that galvanizing devices cannot be cleaned is often encountered, such as ammonia coolers, air coolers, etc., because the galvanized layer is easy to be cleaned The agent is destroyed, resulting in no way to clean the dirt of the galvanizing equipment, which has always been a major problem in the treatment of the dirt of the galvanizing equipment

Embodiment 1

[0023] The special cleaning agent for galvanizing equipment of the present embodiment, its mass ratio is chromic anhydride 10%, citric acid 2%, fatty alcohol polyoxyethylene ether 0.1%, L-826 corrosion inhibitor 0.3%, add water to 100%, described L-826 corrosion inhibitor is benzotriazole.

[0024] The using method of the special cleaning agent for galvanizing equipment of the present embodiment comprises the following steps:

[0025] (1) adopt the special cleaning agent stock solution for galvanizing equipment provided by the invention, and the consumption is determined according to equipment and pipeline conditions;

[0026] (2) The stock solution of cleaning agent is added from the suction port of the circulating pump to form a cycle;

[0027] (3) According to the scale of the equipment, run for 4 to 8 hours, and the circulation pump keeps the cleaning agent circulating, and the cleaning time is inversely proportional to the flow rate of the cleaning agent;

[0028] (4) T...

Embodiment 2

[0031] The special cleaning agent for galvanizing equipment of the present embodiment, its mass ratio is chromic anhydride 10%, citric acid 2%, fatty alcohol polyoxyethylene ether 0.1%, L-826 corrosion inhibitor 0.3%, add water to 100%, described L-826 corrosion inhibitor is benzotriazole.

[0032] The method for using the special cleaning agent for galvanizing equipment of this embodiment is to perform external cleaning on a single galvanizing equipment, including the following steps:

[0033] (1) using the special cleaning agent stock solution for galvanizing equipment provided by the invention, the consumption is determined according to the equipment situation;

[0034] (2) Continuously spray and clean the galvanizing equipment;

[0035] (3) After all the dirt is dissolved, rinse it with water.

Abstract

The invention discloses a cleaning agent special for galvanizing equipment and a using method thereof. The cleaning agent special for galvanizing equipment comprises the following components in mass ratio: 10% of chromic anhydride, 2% of citric acid, 0.1% of fatty alcohol-polyoxyethylene ether, 0.3% of L-826 corrosion inhibitors and the balance of water, wherein the L-826 corrosion inhibitors are benzotriazole. The using method of the cleaning agent special for galvanizing equipment comprises the following steps of: (1) determining the use level of the basic solution of the cleaning agent special for galvanizing equipment in the invention according to equipment and pipeline conditions; (2) adding the basic solution of the cleaning agent from a suction port of a circulating pump to form circulation; (3) running 4-8 hours according to the scale amount of the equipment and keeping the circulating flow of the cleaning agent by using the circulating pump, wherein the cleaning time is in inverse proportion to the flow speed of the cleaning agent; and (4) then replacing by using clean water to discharge pollution until the turbidity is less than 10 mg/L or water is clean by visual inspection.

Description

technical field [0001] The invention relates to a chemical cleaning agent, in particular to a cleaning agent specially used for cleaning galvanizing equipment and its application method. Background technique [0002] In industrial production, galvanizing devices and equipment are very common. In the cleaning of industrial equipment, the problem that galvanizing devices cannot be cleaned is often encountered, such as ammonia coolers, air coolers, etc., because the galvanized layer is easy to be cleaned The agent is destroyed, resulting in no way to clean the dirt of the galvanizing equipment, which has always been a major problem in the treatment of the dirt of the galvanizing equipment. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the object of the present invention is to provide a special cleaning agent for galvanizing equipment and its use method, which can effectively clean the galvanizing equipment with or withou...
