Example Embodiment

[0017] The raw materials and mass percentages used are as follows:

[0018] Potassium hydroxide 2~5%

[0019] Sodium hydroxide 3~6%

[0020] Sodium carbonate 15~20%

[0021] Sodium metasilicate pentahydrate 10~20%

[0022] Sodium tripolyphosphate 10~20%

[0023] Sodium nitrite 10~20%

[0024] Penetrant 1~1.5%

[0025] Non-ionic block polyether surfactant 2~6%

[0026] Surfactant for wax removal 2~6%

[0027] Defoamer 4~6%.

[0028] The amount of each raw material can be selected within the above-mentioned mass percentage range, and the sum of the mass percentages is 100%.

[0029] Preparation method: In the powder drum mixer, start the mixer and calculate the amount of potassium hydroxide, sodium hydroxide, sodium carbonate, sodium metasilicate pentahydrate, sodium nitrite, sodium tripolyphosphate, penetrant (JFC), Non-ionic block polyether surfactants, special surfactants for dewaxing water and defoaming agents are slowly added to the mixer in sequence. Each raw material is added, and it ne...

Abstract

The invention discloses a cleaning and antirust agent for secondary processing of casting parts and a preparation method thereof, and the cleaning and antirust agent has simple cleaning process, high operation efficiency, standard cleaning quality and capability to meet the antirust requirements of preparing process. The agent consists of the following raw materials by weight: 2-5% of potassium hydroxide, 3-6% of sodium hydroxide, 15-20% of sodium carbonate, 10-20% of sodium metasilicate pentahydrate, 10-20% of sodium tripolyphosphate, 10-20% of sodium nitrite, 1-1.5% of osmotic agent, 2-6% of nonionic block polyether surfactant, 2-6% of special surfactant for dewaxing fluid, and 4-6% of antifoaming agent. According to the preparation method of the agent, the above raw materials are gradually added into a mixer in order. The adding of each material is associated with 10-15min of stirring, and when the raw materials are all added, at least 30min are needed to stir the materials continuously.

Description

technical field [0001] The invention relates to a cleaning and antirust agent for metals and a preparation method thereof, in particular to a cleaning and antirust agent for secondary processing castings with simple cleaning process, high working efficiency, up to standard cleaning quality and antirust requirements between processes. method. Background technique [0002] In the surface treatment process of metal products, cleaning is a very important link. The purpose of cleaning is to remove all kinds of oil, rust and residues attached to the surface of mechanical equipment or metal parts, so as to ensure that the coating layer on the surface of the product has sufficient adhesion, thereby ensuring the appearance quality. The secondary processing of castings is to disassemble the castings in the finished product for secondary processing. For example, the secondary engine manufacturing is to import the complete engine from abroad to China after it has been assembled and tes...
