Select ink knowledge dry goods, to answer your questions!

Ink is a kind of material widely used in printing, painting and other fields, it is composed of pigments, resins, solvents and auxilaries. The ink has good adhesion, scratch resistance and light resistance, and is widely used in various fields. The following is a selection of some ink knowledge dry goods, hope to answer your doubts.

First, the composition of ink

1. Pigment: pigment is the main component of ink, which determines the color and color effect of ink. Common pigments are organic pigments, inorganic pigments and metal pigments.

2. Resin: Resin is the colloidal stabilizer of ink, which can make the pigment evenly dispersed in the solvent.

3 Solvent: solvent is the diluent of ink, it can make the ink dilution, flow and dry.

4. Additives: Additives are auxiliary components of ink, including rheological agents, antioxidants, flame retardants, etc. They can improve ink performance and stability.

Second, the classification of ink

1. According to the color of the pigment: ink can be divided into black ink, color ink and metal ink.

2. According to the field of use of ink: ink can be divided into printing ink, painting ink and writing ink.

3. According to the printing method of ink: ink can be divided into lithography ink, relief ink and gravure ink.

Third, the drying process of ink

The drying process of ink refers to the process of ink changing from liquid to solid after printing or painting. The drying speed of the ink depends on the speed of solvent volatilization and resin curing in the ink. Usually, the ink will dry within a few minutes to a few hours, but it may take several days to fully cure.

Fourth, the preservation method of ink

1. Avoid direct sunlight: sunlight will make the pigment in the ink fade and the solvent volatilize, so avoid direct sunlight when saving the ink.

2. Sealed storage: ink should be sealed storage to avoid solvent volatilization in ink and pigment moisture absorption.

3. Low temperature storage: the ink should be stored in a low temperature environment, which can extend the storage time of the ink.

Five, the printing effect of ink

The printing effect of ink is affected by many factors, including ink color, transparency, viscosity, wettability, fluidity and drying speed. Choosing the right ink and printing process can get the ideal printing effect.

Six, the environmental impact of ink

The preparation and use of ink will have a certain environmental impact, including the discharge of waste water, exhaust gas and waste. In order to reduce environmental pollution, effective treatment measures should be taken, such as rational use of solvents, the use of cleaner production processes and recycling of waste.

In SUMMARY:

Ink is an important printing and painting material, which is composed of pigments, resins, solvents and auxiliaries. The composition, classification, drying process, preservation method, printing effect and environmental impact of ink are all knowledge points that we need to understand. Through reasonable selection and use of inks, we can obtain the ideal printing effect and reduce the impact on the environment. I hope the above dry goods can answer your doubts and provide some references.
