5 thoughts on “Why is water -based ink a environmentally friendly ink”

  1. See if an ink is an environmentally friendly ink, it is generally necessary to consider the following points
    The heavy metal content: This concept was first proposed by Germany. Because children often put toys printed with inks into their mouths, there are accidentally absorb heavy metals. The possibility of people began to make requirements for the heavy metal content of ink. Heavy metals are mainly derived from the pigments and auxiliary in the ink. Most of the ink has reduced the heavy metal content, but some people use chromium yellow and chromium red to make inks.
    The aromatic hydrocarbon solvents: major nailine, di toluene, multi -ring aromatic hydrocarbon and its derivatives. They will volatilize in the air with the dryness of the ink, not only polluting the air, but also threatening the health of the printing operator.
    Visible organic compounds (VOC): There are many types of it, such as alcohol, ester, ether, ketone, mineral oil, etc. Like aromatic hydrocarbon solvents, it will volatilize with the dry ink to pollute the air.
    The environmental protection performance is one step further compared with the solvent -type ink. Not only does it contain aromatic hydrocarbon solvents, but VOC is also greatly reduced, but it still cannot achieve zero content. It still contains a small amount of alcohol, ether, and even organic amine. It has a small impact on the environment and is mainly the air pollution.

  2. Features: Due to the use of water as a solubility, water -based ink has significant environmental protection and safety characteristics: safety, non -toxic, harmless, non -burning and no explosive, almost no volatile organic gas generation, mainly manifested in the following three aspects: 1. No pollution environment 2 2 . Reduce residual poison 3. Reduce consumption reduction cost

  3. Water -based ink: Water -based inks are composed of water -based polymer emulsion, surfactant, pigment, water and other additives.

    The advantages: harmless, non -flammable, safe, non -toxic, close to no volatile organic gas. Mainly manifested in the following aspects:

    1. Water -based ink is polluted by the atmospheric environment;
    2. Improve the safety of the operating environment and ensure the health of the operator;
    3, can reduce the printing surface surface the remains;

  4. Water -based ink uses water as a solvents. The emissions of VOCs brought by their house solvent emissions can basically be eliminated, and the characteristics of non -combustion will not bring hidden fire hazards. The potential damage to the body of the printed operator can basically be ignored. Therefore, in some places where safety demand is higher, water -based inks are popular and are accepted by more and more people. Because it is the characteristic of water solvents, it determines that water -based inks will not be discharged and volatile with toxic gases. During the printing process, except for the high concentration VOC above the printing machine The solvents are almost completely dry and volatilized, and the low concentration VOCs permeated in the air in the printing workshop are often directly discharged into the atmosphere. If the proportion of organic solvents in the solvent -type ink is calculated by 25%to 35%, it is directly discharged into the atmosphere The number of VOCs of the environment is quite amazing. Water -based ink just solves this problem. This kind of characteristics of non -pollution of atmospheric environments are being optimistic about more and more printing companies. At the same time, the finished product after printed by water -based ink will not remain toxic substances.

    The water -based ink can be deposited in the thin ink film because of its inherent characteristics. Therefore, for other solvent -type inks, the coating is relatively less. Save about 10%. When printing and cleaning, water -based inks are easier to clean than other inks, and can also save a lot of resources.
