As printed materials such as stamps and printer ribbons, the inkjet ink used for printing needs to be used for a long time. Therefore, pigments with excellent lightfastness and water resistance are required as the coloring components of the ink. It is necessary that the main components of the pigment micro-particles can be evenly dispersed to avoid agglomeration caused by poor dispersion. If the inkjet ink has poor performance in terms of dispersion stability and viscosity, This will make the printed portrait and handwriting unsatisfactory. In addition, as the long-term use of the inkjet printing equipment may cause local temperature rise, the ink is also required to have a certain degree of temperature stability.The ink for ballpoint pens and the addition of PP-K30 in the ink play a role in protecting the colloid, thickening and increasing viscosity, making the writing smooth, without overflow or fading. It can also reduce the…

When the content of the substrate pigment is high, the thixotropy is obvious, the fluidity is poor, and the film is easy to protruding. However, if PVP and other leveling agents are added to the styrene acrylic emulsion, a coating with high pigment content (non-volatile content of more than 70%), high viscosity, good leveling and smooth film can be obtained, and a smooth coating can be obtained by pressing, and the paint amount is less, the luster is good, and the pollution resistance. In recent years, the use of microencapsulation technology can further improve the dispersion stability of pigments, improve the covering ability and anti-fouling properties of coatings. In this paper, vinylpyrrolidone was polymerized in a suspension system composed of pigment and water, the solid particles were dispersed at the same time, and then vinyl acetate monomer and butyl acrylate were introduced to polymerize on the surface of solid particles…

Dimethyl sulfoxide DMSO is dimethyl sulfoxide and has a wide range of uses. Used as a solvent for acetylene, aromatics, sulfur dioxide and other gases and as a spinning solvent for acrylic fibers. It is a very important aprotic polar solvent soluble in both water and organic solvents. It is highly permeable to the skin and helps the drug penetrate into the human body. It can also be used as an additive to pesticides. It’s also a very important chemical agent. DMSO is also a osmotic protective agent, which can reduce the freezing point of cells, reduce the formation of ice crystals, reduce the damage of free radicals to cells, and change the permeability of biofilms to electrolytes, drugs, poisons and metabolites. However, studies have shown that DMSO has serious toxic effects, interacts with protein hydrophobic groups, leads to protein denaturation, and has vascular toxicity and hepatorenal toxicity. DMSO is…

01 Polyvinylpyrrolidone introductionPolyvinylpyrrolidone (PVP) is a kind of synthetic water-soluble polymer, which has been widely used in the biomedical field because of its excellent biocompatibility, chemical stability and versatility. The chemical structure of PVP allows it to be compatible with water and many polar solvents to form a stable solution or gel, a property that brings great potential for drug delivery, tissue engineering, biosensors and many other fields. In recent years, with the development of nanotechnology and materials science, PVP has been expanding its application in biomedicine-providing new ideas and tools for solving clinical challenges.Application of 02PVP in implants and medical devicesThe application of polyvinylpyrrolidone (PVP) in implants and medical devices is mainly due to its good biocompatibility and unique functionality. PVP is commonly used as a coating material for medical devices and implants, which can effectively improve the compatibility of these devices with human tissues. By applying a PVP…

pvpp It is used in beer, wine, tea and other beverage industry stabilizer, is made of vinyl pyrrolidone crosslinked polymerization. It has a slight taste or is tasteless. Insoluble in water, acid, alkali and other solvents, easy to absorb moisture, can expand rapidly in water but no gum formation.Application: pvpp as a stabilizer is widely used in beer, wine, tea beverage, juice and other beverage industry. A white or off-white free-flowing granular powdersummarizeEven if the beer has been filtered, it will still produce precipitation after storage for a period of time. As a result, beer doesn’t last very long. This is caused by polyphenols in beer, polyphenols have a strong ability to cause beer to produce turbidity. PolyFilter is a product that can remove polyphenols from beer, thereby avoiding the formation of unstable turbidity, bringing significant improvements to beer from vision to taste, and greatly extending the storage time of…

1, 2-pentanediol is a straight chain diol, mainly used as a key intermediate of the bactericide propiconazole, and its bactericidal, moisturizing agent, thickening and other multiple properties, often used in skin care products, makeup, shampoo and other personal care products, is also an important raw material for the production of polyester fiber, surfactants, medicine and other products. At present, 1, 2-pentadiol is mainly prepared by the petrochemical route. During the reaction process, 1, 2-epoxy-pentane, peroxides and other substances will be generated and retained in the chemically synthesized 1, 2-pentadiol, which will irritate the skin and lead to skin allergies and other problems. Natural pentadiol is processed, refined and purified by using corn cob/bagasse as raw materials with higher purity. It is basically tasteless, softer and safer for the skin, and is increasingly sought after by the cosmetic field. With the increasing recognition of consumers in the field of green no-add…
