Environment-friendly multifunctional cleaning agent for removing oil and rust and preventing rust and cleaning application method

Abstract

The invention discloses an environment-friendly multifunctional cleaning agent for removing oil and rust and preventing rust and a cleaning application method. The cleaning agent is prepared from the following components in percentage by weight: 0.5-5 percent of composite organic chelating agent, 5-25 percent of surfactant, 0.5-6 percent of a stabilizing agent, 5-15 percent of cleaning auxiliary and 49-89 percent of water. The cleaning agent can be used for replacing trichloro ethylene and dichloromethane cleaning agents, and belongs to an environment-friendly cleaning agent. The method comprises the steps of completely cleaning, rinsing and quickly drying, the cleaning agent having the wetting, permeating, emulsifying, dispersing and capacity-increasing and other performances is combined with corresponding cleaning equipment and cleaning processes, various oil stains, polishing paste and oxides attached to metal surfaces can be once cleaned under the synergistic effect of chemistry and machinery, and a certain oxidation resistance can be achieved; and the cleaning process is simplified, the cleaning process is simple in operation and easy to control, and the cleaning agent is suitable for the requirement of massive cleaning of factories in current electroplating pretreatment.

Description

technical field [0001] The invention relates to an environment-friendly multifunctional cleaning agent for removing wax, oil, rust, and antirust and an application method based on the cleaning agent. Background technique [0002] At present, in the electroplating industry, the pre-plating treatment is very complicated. Including alkali degreasing, trichlorethylene degreasing, electrolytic degreasing, dewaxing water dewaxing, and acid activation, neutralization and other processes. There are many processes, many chemicals are used, and the potions interact with each other, so each process needs to be rinsed with water to avoid the interaction between the potions and reduce the efficacy of the medicine. Therefore, a large amount of water has to be used for rinsing, and the wastewater treatment volume is also large, and the wastewater treatment cost is high; but even so, some workpieces are not rinsed clean, which reduces the efficacy of the liquid medicine and affects the cle...

Problems solved by technology

For example, a Chinese patent once disclosed an "environmentally friendly stainless steel high-efficiency ultrasonic neutral wax removal cleaning agent and its preparation method and use" (authorized announcement number: CN 103741157 B, authorized announcement date: 2016.06.022), the cleaning agent It does not contain phosphorus and will not pollute the environment, but the cleaning agent is mainly aimed at stainless steel products, and the product application range is limited; the cleaning agent concentration is 100% during use, and the transportation cost and packaging cost increase, and the cleaning cost also increases; the cleaning equipment adopts An ultrasonic cleaning tank can be used for small test or small batch cleaning in the laboratory, but when it is used for large-scale cleaning in a factory, there will be problems with unstable cleaning quality

A Chinese patent once disclosed a "wax removal cleaning agent" (authorization announcement number: CN102994284 B, authorization announcement date: 2014.07.09), the cleaning agent can quickly remove waxy dirt on the surface of objects, but the cleaning method is manual scrubbing , not suitable for large-scale cleaning in factories

There are more than 100,000 parts a day, and it is impossible to wipe them manually one by one. The efficiency is low and the effect is poor.

[0004] After more than 20 years of on-the-spot investigations by the applicant in thousands of parts processing factories and electroplating enterprises, it was found that cleaning agents, cleaning equipment, and cleaning processes are seriously mismatched, especially in cleaning application methods.

Most invention patents only stay in the small test operation of the laboratory, without considering the actual needs of large-scale cleaning of the factory
