Water-based ink gravure plate roller

Abstract

The invention relates to a water-based ink gravure plate roller which comprises a roller body and a center shaft connected with the roller body. The roller body comprises a plate cylinder and plugs symmetrically fixed to the two ends of the plate cylinder, the center shaft penetrates through the two plugs and is fixedly connected with the two plugs, the plate cylinder is provided with a nickel-plated layer, a copper-plated layer and a chromium-plated layer from inside to outside, and the outer surface of the plate cylinder is provided with a water-based ink gravure ink cell. Compared with the prior art, the water-based ink gravure plate roller has the advantages of being low in cost, environmentally friendly and the like.

Description

technical field [0001] The invention relates to a forme roller, in particular to a water-based ink gravure forme roller. Background technique [0002] Solvent-based ink is a relatively common type of ink in the domestic gravure printing industry, and it is also the most important ink raw material in gravure printing. Solvent-based ink refers to the use of organic solvents as carriers to dilute wet and dissolved inks. All kinds of solvents used can form toxic and harmful exhaust gases (VOC emissions). The biggest impact of solvent-based inks on environmental protection is the problem of organic solvents. Printing ink consists of pigments, binders, solvents and auxiliary agents. Among them, the organic solvent in the link material is particularly serious to the damage of human body. Organic solvents can dissolve many natural resins and synthetic resins, and are important components of various inks, but some of them can damage the human body and subcutaneous fat. Long-term c...
