Weak solvent ink problem finishing! Is it poisonous? How to use it is environmentally friendly

November 12, 2019


1. What are the harmful effects of weak solvent ink on the human body? Is it poisonous?
Weak solvent inks are still very safe and have low volatility and are slightly toxic. Only long-term contact staff need to use protective measures. As long as the human body does not eat, it is harmless to the human body.


2. What are the characteristics of weak solvent inks? What is the difference compared to solvents?
Compared with solvent-based inks, the biggest change in weak solvent inks is environmentally friendly, mainly due to the reduction of volatile VOCs and the elimination of many toxic organic solvents (such as cyclohexanone, methyl ethyl ketone, etc.). Ventilation is no longer required in the production plant of the solvent jet printer. However, we must see that the main component of weak solvent inks is still organic solvents. Objectively speaking, weak solvent inks are a classification of solvent-based inks and are an environmentally friendly version. The name of the weak solvent ink is ECO-solventink. The ECO can be regarded as the abbreviation of Environmentally Safe, UnCoatedmedia and Outdoordurable. The characteristics of the machine using ECO-solventink are generally promoted. It is environmental protection, high precision and outdoor weather resistance. In the ink production process, in addition to choosing an environmentally friendly solvent, the weak solvent ink also proposes two higher requirements compared with the solvent-based ink: one is to achieve a high-precision output and must have a dot gain on the ink. The control is better, and the other is that the filtration precision of the ink production process is higher.
Since weak solvent inks take into account some of the advantages of aqueous inks and solvent-based inks, it can be said that it has rapidly developed between aqueous inks and solvent-based inks.


3. What are the characteristics of weak solvent inks on the market?
The main characteristics of weak solvent inks are:
(1) Rich colors, realistic effects, wide color gamut, excellent color expression;
(2) Waterproof, resistant to abrasion and not easy to discolor.
(3) Imported raw materials, good dispersion stability, no plugging;
(4) Long-lasting outdoor performance, able to resist the effects of UV light and prevent color fading;
(5) It does not contain toxic solvents such as benzene, toluene, xylene or cyclohexanone, and has a very low taste;
(6) Good adhesion, fast drying;


4. How to better use weak solvent ink?
(1) Due to some characteristics of the weak solvent ink itself, it is necessary to be particularly careful when using the supply. Some friends use weak solvent ink, the outer ink cartridge is leaking, the elbow connecting the ink line is blocked, and finally the print head is broken. So with a corrosion-resistant continuous supply or ink cartridges, especially desktop printers must pay attention to this. Do not use the equipment for a long time, pay attention to the cleaning of the nozzle part, so as to avoid the clogging of the nozzle due to the evaporation and solidification of the residual ink.
(2) Weak solvent inks can be printed on some materials without coating, or by means of printer heating, etc., but for some smooth surfaces, ink alone is powerless, and ink will accumulate in Together, it is impossible to image clearly.
