What kind of RDS squeegee stick is generally used for printing inks?

Printing inks, gravure inks, etc., basically need professional colorimetry and hiding power comparisons between samples and standard products before printing production, so it is necessary to use a squeegee to scrape the coating samples to compare with standard samples or different batches Samples are used for color comparison to ensure the final printing effect.

I often encounter customers asking this question, I want ink proofing, how many RDS squeegee sticks should I use for gravure ink scraping? In fact, this is a question that cannot be answered absolutely, because different specific industries and different specific applications require different printing effects, printing ink layer thickness and color, so it is necessary to follow the actual situation of the customer, the actual sample The parameters of the coating film are required to make the selection.

However, NBCHAO, as a professional self-operated mall for experimental coating equipment, is quite professional in coating equipment, especially experimental wire Bar Coaters and experimental ink scrapers. As the general agent of RDS in the United States, the general agent of RK in the United Kingdom, and the first-level agent of OSP in Japan, there are also other domestic brand manufacturers. This year, the editor also summarized the frequently selected models of RDS based on past ink industry users.

For the ink industry, the models of RDS squeegee sticks are concentrated from No. 4 to No. 9, and the models within RDS No. 6. The winding wire is quite thin, like hair, which is a bit difficult to see with the naked eye. Among them, RDS4#, RDS 5#, and RDS 6# are the most popular choices. The corresponding wet film thicknesses are 9.1 μm, 11.4 μm, and 13.7 μm, respectively.

However, this is for users only as a reference. NBCHAO Mall also has a wet film thickness calculator specially developed for the selection of wire rod coaters, because the key selection of the squeegee rod is the wet film thickness, and the specific squeegee rod number is determined by the wet film thickness. So how to calculate the wet film thickness, the wet film calculator tool can provide a good reference.

The approximate thickness of the coating film can be estimated by the coating amount, density and solid content per square meter. In addition, if you are not sure whether the calculated rod number is suitable for use or whether the RDS wire rod meets your experimental requirements, the unique free trial service of Beichao can also increase your protection.
