Problems solved by technology

However, the existing electrolytic and ultrasonic cleaning agents are not universal, and the hydrochloric acid, sulfuric acid or oxalic acid contained in them, together with the incompatibility of the additives and corrosion inhibitors used, lead to the following problems:
[0003] 1. Corrosion of stainless steel tanks of electrolysis and ultrasonic equipment;
[0004] 2. The cleaning speed is slow, the temperature condition is high, and sometimes the problem of incomplete cleaning occurs

Abstract

The invention discloses an electrolytic ultrasonic united cleaning and removing agent for plastic die high temperature hardening plastic film residues, the electrolytic ultrasonic united cleaning and removing agent comprises the following raw materials: by mass, 5-10% of potassium hydroxide, 5 ~10% of sodium hydroxide, 3-5% of ethylenediaminetetraacetic acid disodium salt, 3-5% of oleic acid triethanolamine, 3-5% of diethylene glycol monobutyl ether, 3 ~5% of dipropylene glycol methyl ether, 6-8% of acetone, 1-2% of a carbon deposit removing surfactant, 1-2% of a wax solvent special surfactant, 1-2% of a strong alkali resistant electrolytic degreasing special low foaming surfactant, 0.1-1% of a defoaming agent and the balance of water. The electrolytic ultrasonic united cleaning and removing agent can be generally used in electrolytic and ultrasonic cleaning, is convenient to use, and does not contain hydrochloric acid, sulfuric acid or oxalic acid and other strong corrosive acids, the selected additives, corrosion inhibitors and the like are reasonable in matching, the electrolytic ultrasonic united cleaning and removing agent has optimal effective pickling solution concentration, additive strengthening effect, surface tension, viscosity coefficient, vapour pressure in ultrasonic equipment, and the like, can avoid corrosion of electrolytic and ultrasonic stainless steel cleaning equipment, and can quickly and completely remove the plastic die high temperature hardening plastic film residues.

Description

technical field [0001] The invention relates to a cleaning agent for plastic mold high-temperature hardening plastic residual film, especially a non-corrosive electrolysis and ultrasonic cleaning equipment, which can quickly and completely remove plastic mold high-temperature hardening plastic residual film. Detergent. Background technique [0002] A large amount of high-temperature hardened plastic film will remain on the surface of the plastic mold, which needs to be cleaned by electrolysis or ultrasonic waves. Electrolytic cleaning mainly uses the principle of electrolysis to remove dirt on the surface of plastic molds, also known as electrochemical cleaning; the main mechanism of ultrasonic cleaning is that the tiny bubble nuclei in the cleaning agent vibrate, grow and burst suddenly under the action of ultrasonic waves. At the moment when the bubbles burst, the impact force of up to thousands of atmospheres is enough to break the residual film, and the local high tempe...
