Sublimation ink

At present, the heat transfer is the attention and favor many, many people love more, technical requirements for higher. We produce a better picture, heat transfer ink is a big problem!

1. composition of sublimation inks

Ink solvent, usually by coloring agent, surface active agent, PH regulator, drying agent and other necessary additives. Among them, the solvent in the ink jet printer in the largest proportion, is the major component of. And the colorant directly affects the performance of printing the image color and tone, its color, mixed properties, solubility, PH, particle size is important.

2. the main performance parameters of sublimation inks

Inkjet printer ink requires very high heat and chemical stability. The main parameters of the ink to print the results are the following:

1. viscosity and surface tension of the liquid flow resistance: viscosity, the surface tension of the liquid is related to whether the formation of droplets, generally speaking, inkjet ink should have a low viscosity, high surface tension, to ensure good flow properties and droplet morphology.

2. PH value: concept liquid PH, the solution is acid, PH value is low, and vice versa, the alkali solution, the higher PH value. In order to prevent ink corrosion nozzle, PH should be between 7-12.

3. in the ink, conductivity, conductivity value is used to reflect the salt content. In general, the salt content of not more than 0.5%, to avoid crystallization is formed in the nozzle blockage caused by.

4. dispersant: one kind of surface active agent, its main function is to improve the physical properties of the surface of ink, enhanced affinity, wet ink with a sponge. So the general through the sponge storage, transfer the ink containing dispersant.

Choose the best quality materials, refer to the above parameters.
