Problems solved by technology

[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...

Embodiment

[0012] The decalcifying agent of this embodiment is made of the following raw materials: phosphoric acid 10, sulfamic acid 5, citric acid 14, thiourea 1, sodium hydroxycellulose 2, deionized water 70, 200 mesh pumice powder 0.3, oil Sodium 1, sodium dodecylbenzene sulfonate 2, additives 2.

[0013] The auxiliary agent is made of the following raw materials in parts by weight: sodium carboxymethyl cellulose 2, molybdenum disulfide 1.5, deionized water 8, tea polyphenols 2, tannic acid 0.1, and the preparation method is as follows: Tannic acid was poured into deionized water, stirred until it was completely dissolved, then sodium carboxymethyl cellulose was added, and the stirring was continued until it was completely dispersed, then molybdenum disulfide was poured in, and after stirring and dispersing for 50 minutes, the resulting material was heated to Concentrate to a paste at 50-60°C and get it.

[0014] The preparation method of the decalcifying agent is:

[0015] (1) First put ...

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...
