Metal products, printing special silicone features-HongYe silicone

Full range of printing plastic, according to the substrate material can be divided into many types, existing printing plastic process can be made to adapt to most of the material printing plastic head, it should be said that the domestic printing plastic technology is relatively mature, One of the most special kind of metal products, printing special silicone. The name implies, metal products, printing special silicone substrates made of metal, its hardness, character, situation of the surface coefficient, ink adsorption, etc., are ordinary products printing plastic significant differences in the following by the author to briefly metal products, printing special silicone should have features.
Metal products, printing special silicone should have the following features:
A. Good ink absorption and de-inking
Metal products, most of the higher density, such as plastic material, adsorption after adsorption of the ink does not very easy to de-inking, ink absorption and de-inking is a contradiction, in fact it means that the ink layer by the equilibrium pressure from the diffusion of high concentration to low concentration. When dipped in ink, metal products, printing gravure inks at high concentration, low concentration of metal products, printing special silicone head surface layers of ink, plastic header compression deformation, metal products, printing special silicone header compression and gravure ink concentration will re-distribution, which is part of the ink layer by a plastic head surface adhesion attract stick to the plastic head surface, another part by the attraction of the intaglio surface adhesion residue in the intaglio surface, this time for the glue head suction ink. Plastic head with the substrate contact is mainly for deinking. The first plastic compressive deformation of the surface of the ink separation. Part of the ink transferred to the substrates, the surface of another part of the stay in the plastic head.
Two. Good elasticity
Metal texture of the product is hard traits to undertake at the sleek, metal products, printing special silicone rubber head deformation in ink, but also in the deformation de-inking. Graphics were flat-shaped metal products, printing special silicone steel version of the substrate surface is flat, so in order to ensure that graphics are not deformation, permanent deformation of the printing plastic head and the printing plastic head with good resilience to crucial. In the mid-term life expectancy, printing plastic head a slight deformation (unrecoverable), will give a serious impact on printing quality.
         
3. Good solvent resistance
Metal products, printing special silicone rubber head must have a corrosion resistant ink in a variety of solvents. Screen printing inks and printing ink are usually the viscosity of the solvent-based ink, solvent gasoline solvent, ethyl acetate, acetone, acetic acid, small vinegar, methyl ethyl ketone (MEK), cyclohexyl ketone, etc. Experimental results show that silicon rubber printing plastic head has a good resistance to the above-mentioned solvent resistance.
