Abstract

The invention relates to the field of PS/CTP printing, and particularly relates to a flexible scale-inhibition calcium remover for a plate developing machine, and a preparation method thereof. The calcium remover is prepared from the following raw materials in parts by weight: 10-14 parts of phosphoric acid, 2-4 parts of aminosulfonic acid, 2-5 parts of citric acid, 1-2 parts of thiourea, 4-8 parts of polyacrylic acid, 60-80 parts of deionized water, 1-2 parts of aluminum-magnesium silicate, 1-3 parts of alkyl glycoside, and 1-3 parts of auxiliaries. According to the calcium remover, a mixed solution with wide cleaning range is prepared by mixing materials of phosphoric acid, aminosulfonic acid, citric acid, polyacrylic acid and the like, the calcium remover has excellent dissolving capacity on various metal precipitate salts and calcium, the surface hardening layer of a rubber roll can be fast disintegrated, aluminum-magnesium silicate is swelled and dispersed in the solution and has certain adsorbability to fast adsorb an eluate, the cleaning speed is increased, the later-stage cleaning is more convenient, and by combining the auxiliaries and other components, the calcium remover is good in cleaning capacity, mild and fast to clean, incapable of damaging the plate developing machine, and stable and storage-resistant in the performance of a finished product.

Description

technical field [0001] The invention relates to the field of PS / CTP printing, in particular to a flexible scale inhibitor and decalcifier for a plate processor and a preparation method thereof. Background technique [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. If the ink cannot adhere, it will be difficult to follow the color of the printing or the color difference will deviate. 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, it is necessary to regularly decalcify the layout. Contents of the invention [0003] The object of the present invention is to provide a kind of flexible...
