Problems solved by technology

However, when using these pure acidic cleaning solutions to clean, it is easy to cause corrosion to the metal parts inside the developing machine, making the rubber roller of the developing machine old, and the brush grinding roller hardened, which in turn causes scratches on the plate surface during the developing process. , developer leakage and other phenomena, in addition, the service life of the developer is greatly shortened, so it is necessary to provide a cleaning solution to effectively and reliably clean the scaling and crystallization in the developer, and clean the internal components of the developer Cleaning agents or cleaning fluids with low corrosive effect

Abstract

The invention discloses a cleaning agent for development equipment. The cleaning agent comprises 5-30 parts by weight of a main agent of and 3-15 parts by weight of an auxiliary agent, wherein the main agent consists of one or more of sulfonamic acid, sulfosalicylic acid, citric acid, phosphoric acid and glycollic acid; the auxiliary agent consists of one or more of oxalic acid, ammonium bifluoride, maleic anhydride and polyethylene phosphate. The cleaning agent consisting of the main agent and the auxiliary agent in weight ratio is configured into a cleaning solution to clean the development equipment, so that scales and crystals in the development equipment are effectively removed, meanwhile, the corrosion rate of the cleaning solution to the development equipment is reduced during cleaning, the development equipment is protected, and the service life of the development equipment is prolonged.

Description

technical field [0001] The invention relates to the field of printing plate production, in particular to a cleaning agent for developing equipment used in the production process of printing plates and a usage method thereof. Background technique [0002] The developing machine is mainly used for the development process in the production process of PS plates and CTP plates. The development of PS plates and CTP plates commonly used at this stage is based on the principle of acid-base neutralization to dissolve the photosensitive film layer of the non-patterned part, thereby Complete the development work. The developing machine soaks the exposed plate in the developer solution through the mechanical transmission of its internal mechanism and the manipulated spray and brush roller operation, and cleans the plate surface in a continuous running state to achieve the purpose of development. The main agent of the developer is mostly composed of alkaline components such as sodium hy...
