What is ink?


Ink is a uniform mixture composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling materials, additional materials, etc.; it can be printed and dried on the printed body; it is colored and has a certain flow. Degree of paste-like adhesive body. Therefore, color (hue), body (rheological properties such as thinness and fluidity) and drying performance are the three most important properties of ink. There are many types of inks, and their physical properties are also different. Some are very thick and sticky; while others are quite thin. Some use vegetable oil as the linking material; some use resin and solvent or water as the linking material. These are determined according to the printed object, that is, the substrate, the printing method, the type of printing plate, and the drying method.

Development of ink industry


● The development of the ink industry is affected by various factors such as upstream raw material prices, downstream printing demand, environmental protection policies and technological innovations.

● The main trend of the ink industry is to develop in the direction of green environmental protection, high efficiency, diversification and intelligence, so as to meet the printing needs of different fields and levels.

● Main products in the ink industry include gravure inks, lithographic inks, offset inks, flexo inks, water-based inks, UV inks, special inks, etc. Various inks have different advantages and applications in different printing methods and fields. With the advancement of human civilization and the development of the printing industry, substrate materials are constantly being developed and expanded, and printing methods are constantly being introduced. The production process of ink is more sophisticated, and the types and varieties of ink products continue to increase. For example, the promotion of waterless offset printing technology has increased the demand for waterless offset printing inks, and the rise of flexible digital printing has also brought digital printing inks to the stage of history.

● The ink industry presents different development trends on a global scale. Europe and the United States are the traditional major ink production and consumption countries. Asia and the Asia-Pacific region are the growth engines of the ink market. China is the second largest ink production and consumption country in the world. It has huge market potential and development space.


What is Volatile Organic Compounds (VOC)


A volatile organic compound (VOC) is an organic compound with a high vapor pressure at room temperature, which can volatilize in the air and participate in atmospheric photochemical reactions, affecting air quality and human health. There are many types of it, according to its chemical structure, it can be divided into alkanes, aromatics, alkenes, halocarbons, esters, aldehydes, ketones, etc., and more than 300 kinds have been identified. The sources of volatile organic compounds (VOC) are also complex, including industrial production, transportation, daily necessities, architectural decoration, office equipment, etc.


The printing ink industry is one of the important sources of VOC emissions, because the ink contains a large amount of organic solvents, pigments, resins and other components. In order to reduce the harm of the printing ink industry to the environment and the human body, countries around the world have formulated some laws and regulations, standard specifications, technical measures and management measures to control the VOC content and emissions in printing inks. In addition to laws, regulations and standard specifications, countries around the world have also adopted some technical measures and management measures to control the VOC content and emissions in printing inks, such as source control by using low-VOC or VOC-free raw and auxiliary materials, and by improving printing Process control of process and operation mode, terminal control by installing VOC treatment equipment, and establishment and implementation of environmental management systems, such as ISO 14001, EMAS, etc., to improve the environmental awareness and sense of responsibility of printing companies, as well as the monitoring and recording of VOC emissions ability.


Application of precipitated barium sulfate in printing ink industry


Our company specializes in the production of special precipitated barium sulfate, the particle size is controllable, the median particle size is from 30 nanometers to 10 microns, and we focus on providing customized products and services. It is worth mentioning that we can customize products according to customer needs Different surface treatment, which also means that our products can be equivalent to the international Blanc Fixe.


The main components of ink are pigments, resins, solvents and additives, among which pigments are the key factors affecting the color and quality of inks. As an inorganic pigment, precipitated barium sulfate can play the role of whitening, brightening, thickening, weighting and filling in the ink, improve the covering power, leveling and adhesion of the ink, and reduce the cost and viscosity of the ink , Extend the service life of the ink.

At the same time, our precipitated barium sulfate can also contribute to the environmental protection of inks, because it has the following advantages:


● Our precipitated barium sulfate is a non-toxic and harmless substance, which will not cause harm to the human body and the environment, and meets international environmental protection standards.

● Our precipitated barium sulfate can reduce the use of organic solvents, increase solid content, reduce emissions of volatile organic compounds (VOC), and reduce air pollution.

● Our precipitated barium sulfate can be modified by silicon and aluminum to improve the weather resistance and light resistance of the ink, prolong the shelf life of printed matter, reduce the fading and aging of printed matter, and protect the beauty and value of printed matter. At the same time, it can effectively improve the suspension and thixotropy, maintain the stability of color tone for a long time, reduce the amount of pigment, and improve its color rendering.

● Our precipitated barium sulfate can increase the solid content and drying speed of the ink, shorten the printing cycle, save energy and resources, and improve production efficiency and economic benefits.

● It can also replace German and Japanese products, reduce costs, and achieve better gloss and color development!
