Technical Field

The invention relates to the technical field of plastic cleaning, in particular to a cleaning agent and a cleaning method.

Background

With the development of science and technology, the exposure and development process is widely applied to electronic products, and a jig is required to be used in the exposure and development process to solve the problems of exposure and development overexposure, abnormal color points, dirt and the like, wherein the jig is made of a plastic material; after exposure and development, ink is left on the plastic jig, so that the plastic jig needs to be cleaned to ensure the quality of a product; the neutral detergent can not wash off ink left after the plastic jig is exposed and developed, so that an alkaline detergent is needed. The existing alkaline cleaning agent comprises the following formula: 25-30% of sodium carbonate, 3-5% of EDTA disodium, 103-6% of OP-103%, 8-15% of diethylene glycol ethyl ether and the balance of water. The pH value of the alkaline cleaning agent prepared by the formula is 12-13, and the cleaning agent can cause the plastic jig to be corroded and softened and the cleaning yield of the jig is low, so that the jig is damaged and the economic cost is increased.

In view of the above, there is a need for a cleaning agent that can clean a plastic fixture without damaging the fixture, so as to solve the problems in the prior art.
