Where is the environmental water-based ink? Printing ink is a slurry-like colloid composed of pigments, binders, fillers and other ingredients mixed uniformly. As a viscous fluid ink, due to its varieties of different performance is also different, such as, difference between thick and thin, difference between strength of viscous, fast dry and slow dry, etc. Environmental ink is a new type of ink made of environmental materials Usually, to see whether an ink belongs to environmental ink or not, will need to consider the following points: *Content of heavy metal The concept was first proposed by Germany. Since children often put ink-printed toys into their mouths, there is the possibility of accidental absorption of heavy metals, so people began to put forward requirements on heavy metal content of ink. Heavy metals mainly come from pigments and additives in inks, most of the ink has reduced the content of heavy metals, but some people still use chromium yellow, chromium red to produce ink. *Aromatic solvent Mainly refers to toluene, xylene, polycyclic aromatic hydrocarbons and their derivatives. They will be accompanied with the ink drying volatilized into the air, not only polluting the air, but also threatening the health of printing workers. *Volatile Organic Compounds (VOC) There are many kinds of it, such as alcohol, ester, ether, ketone, mineral oil and so on. Like the aromatic hydrocarbon solvent, it will volatilize as the ink dries, thereby polluting the air。 At present, the main environmental ink including water-based ink, UV ink, water-based UV ink and high-temperature glass ink. Water-based Ink Compared with solvent-based ink, water-based ink is more environmental. Not only does it not contain aromatic hydrocarbon solvents, but VOC is also greatly reduced, althought it cannot achieve zero content, and still contains a small amount of alcohol, ether, and even organic amines. It has little impact on the environment, mainly polluting the air in the workshop. However, a significant reduction in VOC emissions can effectively reduce atmospheric pollution, the content of which does not affect human health, not easy to burn, and will not cause a crisis or induced secondary pollution. Due to the higher difficulty factor of the requirement, relatively, the product quality will be excellent. But there are not many manufacturers that can make water-based ink. This has a great relationship with the match application of raw materials, especially the extremely high requirements for production and preparation. UV Ink UV Ink is those that, under ultraviolet irradiation, use different wavelengths and energies of UV light to make ink into film and dry ink. UV ink does not contain volatile organic compounds, from this point of view, it is a big step, and it is safer than water-based ink. But its drying is achieved by ultraviolet light, water-based UV ink, same as water-based ink, has a small amount of volatile organic solvents, compared with ordinary UV o...

Manufacturing industry is facing new challenges --as the new coronavirus epidemic spreads globally. At present, with the strong measures of the government such as the closure of the city of Wuhan and the delay of the resumption of work nationwide, as well as the joint efforts of front-line workers and people, the spread of the Covid-19  in China has slowed down. However, the global trend of corona virus outbreaks is not optimistic, the world health organization (WHO) on February 28 new pneumonia from the previous "high" global risk level to the highest level of "very high". From Europe to America, from Far-east to Middle east...With the worsening of the epidemic outside China, the global economic recovery is greatly hindered, the global manufacturing industry is facing new challenges! The impact of the new corona virus outbreak on global manufacturing is already being felt As the World Bank's world development index (WDI) shown, China has become the largest trading partner of more than 120 countries by 2018. According to the World Comprehensive Trade Solutions database jointly released by the World Bank and the United Nations Conference on Trade And Development (UNCTAD), nearly 200 economies in the world import goods from China, of which intermediate goods account for an average of 21.7 percent. China is now the hub of a network of global supply chains, and Chinese manufacturing is crucial to many global value chains, particularly those related to precision instruments, machinery, automobiles and communications equipment. Any major disruption to Chinese supply in these areas would have a big impact on producers in the rest of the world. The spread of the new coronavirus outbreak in early February has had a huge impact on global manufacturing. UNCTAD's latest report shows that, just is a disruption of China supply chains,  the largest economy in the affected may be the European Union (machinery, automobile and chemical products), the United States (machinery, automobile and precision instruments), Japan (machinery and automobile), Korea (machinery and communications equipment), Taiwan, China (communication equipment and office equipment) and Vietnam (telecommunications equipment). Take the electronics and automotive industries China imports semiconductors and electronic components from South Korea, Taiwan and Japan, and then gathers in our electronic manufacturing service factories to supply final products to the world. About 65% of the world's smartphones and 45% of its PCS are made in China, and the outbreak has disrupted entire manufacturing supply chains. A survey by IPC, the electronic equipment guild, found that 65% of the 150 electronics manufacturers and suppliers surveyed reported delays in both production and delivery due to the new outbreak. For example, the global supply of Apple's iPhone is temporarily constrained, Dell has been badly affected by its just-in-time production model, and so on. Wuhan, the outbreak of the epidem...

What is the difference between horizontal and vertical bead mill? What is the difference between horizontal and vertical bead mill? Bead mill is a kind of super - fine grinding equipment for wet process, now it is widely used in ink, pigment dispersing and grinding. There are different kinds of bead mills, from the installation form, it can be divided into vertical and horizontal. What is the difference between them? 1 - Horizontal Bead Mill Horizontal bead mill is a kind of high efficiency wet ultrafine grinding and dispersing machine widely used in coating, dye, paint, ink, medicine, ferrite, photosensitive film, pesticide, papermaking and cosmetics industries. According to the different structure, horizontal bead mill can be divided into ordinary horizontal bead mill, wheel pin horizontal bead mill, tooth disc horizontal bead mill and turbo horizontal bead mill! Horizontal bead mill is a kind of horizontal wet continuous ultrafine particle dispersing machine. Send the pre-stirred raw material to grinding chamber, the chamber is filled with appropriate amount of grinding media, such as glass beads. Through dispersing blades in high-speed rotation, the grinding media was given with enough momentum, to produce shear force by collision with the dispersed particles, to achieve the effect of dispersing, then through the special separation device, discharged the material and grinding media separately. Horizontal conical bead mill is characterized by advanced design, closed continuity of production, uniform grinding fineness, good quality, high production efficiency, double mechanical seal, dual protection, zero leakage, a new dynamic separation mechanism, discharge quicker. It is widely used in paint, dye, printing ink, sensitive material, medicine and other industries. Horizontal bead mill is especially suitable for dispersing and grinding products with high viscosity and fine particle size.Horizontal bead mill is a kind of horizontal wet continuous ultrafine particle dispersing machine.

Since it is grinding in the fully closed grinding chamber, so there is no solvent volatilization air pollution problem, to ensure the physical and mental health of staff. The vertical integral design integrates the bead mill host, feeding pump and e...

How to deal with the “troublemaker” of the slurry - air bubbles? Many people may have the same problem when producing slurry, there are too many bubbles in the material. If these bubbles are not removed in time, it will often cause serious consequences-for example, bubbles in ceramic slurry will cause more pores in the blank body after molding. Bubbles in textile slurry will affect penetration and make sizing uneven. Bubbles in electronic slurry will affect the capacity and service life of the product. Bubbles in coating will cause surface defects in the application of the product, which will not only damage the appearance, but also affect the corrosion resistance and weather resistance of the coating film. Ceramic slurry with bubbles Therefore, in many similar production occasions, "deaeration" has become a very critical step in the process. As for how these bubbles come from and how they go, please see below for details. Causes of slurry foaming and bubbling The generation of air bubbles in liquids is a very complicated problem. The generally accepted view of the formation mechanism of bubbles in liquids is cavitation phenomenon, that is, due to its certain solubility, the gas usually exists in the liquid as bubble core. When the liquid flows through a region with a very low absolute pressure in a very short time, the bubble core will quickly evaporate or dissociate. If you want these bubbles to disappear naturally, usually will need to wait for four stages: the bubbles move to the liquid surface - Liquid film is formed at the interface - Film ruptures - Bubbles separate from the liquid surface or the bubbles burst. Ways to deal with bubbles At present, there are three main ways to eliminate the bubbles generated in the slurry producing process: ①Use defoaming agent: defoaming agent can be added in twice, before slurry preparation and at the end of slurry preparation. ②Slow stirring: put the slurry in the container and stir slowly. ③Vacuum method: slurry in a closed container to stir, while keeping the container in a vacuum state (use a vacuum pump). The reason why defoaming agent can defoam is mainly because when defoaming agent diffuses in the foam, it will form a double film on the foam wall. During this diffusion process, the stabilizing surfactant is displaced, and reduce the local surface tension of the foam, destroy the self-healing effect of the foam, so that the foam burst. But since the defoaming agent may react with the compound in the slurry or affect the performance of the slurry, the vacuum method is more common, especially in high viscosity slurry. This is because the bubbles in high viscosity slurry rise very slowly by their own buoyancy, so they must rely on external force to bring the bubbles to the liquid surface. Currently, the more effective vacuum defoaming method include vacuum stirring defoaming and vacuum film defoaming. 1、Vacuum stirring defoaming method For the stirring of high-viscosity liquids, slow-type stirre...
