Calcium remover for PS (Poly Styrene) plate/CTP (Cytidine Triphosphate) plate developing machine and preparation method of calcium remover

Abstract

The invention relates to the field of PS / CTP printing and particularly relates to a calcium remover for PS (Poly Styrene) plate / CTP(Cytidine Triphosphate) plate developing machine and a preparation method of the calcium remover. The calcium remover is prepared from the following raw materials in parts by weight: 10-12 parts of phosphoric acid, 4-6 parts of sulfamic acid, 12-15 parts of citric acid, 1-3 parts of thiourea, 1-3 parts of sodium hydroxy cellulose, 60-80 parts of deionized water, 0.2-0.5 part of pumice powder of which the granularity is 150-400 meshes, 1-2 parts of sodium oleate, 1-3 parts of sodium dodecylbenzenesulfonate and 1-3 parts of additives. According to the calcium remover, a clean and wide-range mixed acid solution is prepared from phosphoric acid, sulfamic acid, citric acid and the like, the calcium hardened layer can be quickly disintegrated, since the solution also has a certain viscosity, the fall-off calcareous layer can be bonded so that the post-cleaning is more convenient; since pumice powder is added, the solution has a certain friction force when the solution is used for scrubbing so as to accelerate fall-off and disintegration of the calcareous layer; in combination with the additives and other components, the calcium remover has strong cleaning capability and is easily cleaned and no damage on the surface of the treated rubber roller is caused and the inking does not be affected.

Description

Technical field [0001] The invention relates to the field of PS / CTP printing, in particular to a decalcifying agent for a PS plate / CTP plate punching machine and a preparation method thereof. Background technique [0002] During the printing process, as the printing time accumulates, the calcium in the paper, the minerals in the tap water and the metal compounds in the ink can easily form a calcium accumulation layer in the rubber roller, causing the surface of the rubber roller to glaze and harden. The ink cannot be attached, the printing and the color are difficult, or the color difference occurs. If it is not handled in time, the service life of the rubber roller can be greatly shortened, which will increase the production cost and reduce the production efficiency. Therefore, the layout must be regularly decalcified. Summary of the invention [0003] The purpose of the present invention is to provide a decalcifying agent for a PS plate / CTP plate punching machine and a preparati...

[0002] During the printing process, with the accumulation of printing time, the calcium in the paper, the minerals in the tap water and the metal compounds in the ink can easily form a calcium accumulation layer in the rubber roller, resulting in the surface of the rubber roller being glazed and hardened. The ink cannot be attached, and the printing is difficult to follow the color or the color difference is deviated. If it is not dealt with in time, the service life of the rubber roller will be greatly shortened, thereby increasing the production cost and reducing the production efficiency. Therefore, the layout must be regularly decalcified
