Ink printing with bright color, good adaptability, ink is a certain fluidity of paste adhesive, viscosity, negative, thixotropy, liquidity, dry decides the performance of ink, printing ink to add fertilizer, to improve the ink printing eligibility, such as viscosity, viscosity, dry, etc. With the development of printing technology, the variety of ink is increasing, and there are many methods of cl...
The fluidity of ink includes viscosity, adhesion, viscoelasticity, and yield value and thixotropy.It mainly depends on the nature of pigment and binder, and its manufacturing process, the content of binder directly affects the fluidity of ink. In the printing press, the flow phenomenon is mainly manifested in the following three aspects: (1) When the container is poured into the ink...
Ink output by the ink hopper flow phenomenon called ink ink. When the ink is output by the ink roller, it is only affected by the external force of the ink roller. The flow conditions are mainly the gravity and surface tension of the ink itself, and the inking of the ink depends on its own fluidity, but also on its own flow, viscosity, yield value, thixotropy, drawing and other rheological propert...
After ink roller output, the flow phenomenon is called ink transfer. In the process of printing, the thickness and uniformity of the ink layer on the surface of the image and text of the plate are achieved by a series of ink rollers. Therefore, the quality of ink transfer is directly related to the ink distribution and distribution, and the smooth transfer of ink in the whole process. Generally sp...
Ink in the transfer, distribution (from the ink hopper ink, after complex transfer and distribution, until the smooth transfer to the surface of the printing sheet to form a blot), the flow phenomenon is called the transfer of ink, it is the main body of ink operation adaptability. The transfer of ink can be understood from two aspects: On the one hand, ink transfer, uniform ink and ink roller tra...
After the ink is transferred to the printing surface by the blanket at a certain printing speed and under a certain printing pressure, the fixation and drying speed of the ink film, as well as the color, gloss, fastness and resistance after film formation, etc. ensure the printing effect, which are collectively referred to as the printing quality suitability of the ink. It mainly includes color, p...
Screen printing UV pressure sensitive adhesive and screen printing water-based pressure sensitive adhesive, has the following different characteristics: because UV curable pressure sensitive adhesive does not contain water or organic solvent, so it can be cured without heating drying channel, and water-based pressure sensitive adhesive to water as diluent, need a lot of heat to volatilizing water;...
Water-based adhesive with high polymer, water-soluble resin as the main raw materials, water as the solvent, less odor, environmental protection. With the continuous improvement of people's environmental awareness, water-based adhesives have become the mainstream of the market in recent years. Characteristics of water-based adhesive 1.Applicable to the substrate any kind of adhesive is not om...
Polyurethane (PU) is a kind of organic polymeric compounds containing repeated carbamate group (NHCOO) in the main chain.Polyurethane polymer materials have the advantages of wear resistance, high temperature resistance, good adhesion, easy processing, low price, but some polyurethane water resistance, heat resistance is poor, need to be modified by specific methods, in order to achieve the purpos...
Together to understand the characteristics of water-based acrylic emulsion! 1.Excellent adhesion The polymer structure of water-based acrylic emulsion contributes to the flow and wettability of molecular chains on the substrate surface, making the coating and substrate molecules in close contact, to achieve high adhesion 2.High load-bearing capacity of the makeup filler can significantly reduce th...
Preparation method of waterborne acrylic emulsion 1.The preparation of water-based acrylic emulsion: the raw materials including acrylic hard monomer, acrylic soft monomer and acrylic functional monomer all acrylic monomer, emulsifier, water added to the pre-emulsifying kettle, emulsifying 30 ~ 40min.A non-stratified emulsion is obtained. Then the remaining water, remaining emulsifier and buffer a...
Acrylic resin is made of acrylic ester and methacrylate and other alene monomers copolymerization resin, through the selection of different resin structure, different formula, production process and solvent composition, can be synthesized different types, different performance and different application of acrylic resin, Acrylic resin can be divided into thermoplastic acrylic resin and thermosettin...
Polyurethane (polyurethanes, abbreviated PU) is a kind of polymer with -NHCOO-repeat structural unit as the main chain. Isocyanate (monomer) is polymerized with a hydroxyl compound.Due to the strong polarity of the carbamate group, insoluble in non-polar groups, with good oil resistance, toughness, wear resistance, aging resistance and adhesion. Materials suitable for a wide temperature range (-50...
Labels, as they are called in the printing industry, are mostly printed materials used to identify the relevant instructions of their products, and most of them come with glue on the back. But there are also some printing without glue, can also be called labels. Glue label is colloquially known as "sticker label". Label base material classification Substrate application surface material paper...
Self-adhesive refers to paper, film or other special materials as fabric, coated with adhesive on the back, a composite material printed with silicon protective paper as the base paper, the reason for the rapid rise of self-adhesive in recent years, because it is very practical, and very convenient, the cost is not high, the following to tell you about a few small knowledge of self-adhesive printi...
Water based adhesive for a more sustainable bond The market share of water-based adhesives is becoming increasingly large as development has shifted towards increasingly sustainable solutions that support health and safety and reduce environmental impact.Water-based adhesives are an excellent alternative to solvent-based systems because they do not contain any volatile organic compounds (VOC), are...
