Special calcium remover for edition developing machine and preparation method of special calcium remover

Abstract

The invention discloses a special calcium remover for an edition developing machine. The special calcium remover is prepared from the following raw materials in parts by weight: 5-6 parts of citric acid, 20-30 parts of tartaric acid, 2-3 parts of acetic acid, 3-4 parts of nano silicon dioxide, 5-6 parts of stearic acid, 1-2 parts of diethylene glycol, 2-5 parts of dodecyldimethyl betaine, 3-4 parts of cocoanut fatty acid diethanolamide, 3-5 parts of nonylphenol ethoxylates, 4-5 parts of composite auxiliaries and 40-50 parts of water. The special calcium remover for the edition developing machine, disclosed by the invention, can be used for effectively removing calcium salt on an ink roller and particularly used for turning ink from a dark color to a light color and cleaning gold ink and silver ink and is low in dosage and very good in ink cleaning effect.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a special decalcifying agent for plate processors and a preparation method thereof. Background technique [0002] During the printing process, due to the calcium on the surface of the paper, the minerals in the tap water and the metal compounds in the ink, as the printing accumulates for a long time, a smooth mirror surface or white calcium will be formed on both sides or in the middle of the surface of the rubber roller. Quality, at the position of the rubber roller that forms the calcium surface, the ink cannot be applied to the smooth surface of the rubber roller, resulting in difficulty in printing and coloring or the deviation of the color at both ends. When the calcium is serious, the calcified position will appear on the rubber surface The serious consequences of degumming and sand pits end the service life of the rubber rollers in advance, increase the difficulty of the ope...

Problems solved by technology

[0002] During the printing process, due to the calcium on the surface of the paper, the minerals in the tap water and the metal compounds in the ink, as the printing accumulates for a long time, a smooth mirror surface or white calcium will be formed on both sides or in the middle of the surface of the rubber roller. Quality, at the position of the rubber roller that forms the calcium surface, the ink cannot be applied to the smooth surface of the rubber roller, resulting in difficulty in printing and coloring or the deviation of the color at both ends. When the calcium is serious, the calcified position will appear on the rubber surface The serious consequences of degumming and sand pits end the service life of the rubber rollers in advance, increase the difficulty of the operator's color matching and delay the working hours and increase the production cost. Therefore, the regular maintenance and decalcification of the rubber rollers are very important processes.

The method of decalcifying with decalcifying agent is very common, but most of the existing decalcifying agents are more corrosive and not environmentally friendly. The decalcifying agent of the present invention is less corrosive, has high environmental protection performance, and does not pollute the environment
