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...
Water-based single-component protective film adhesive is an environmentally friendly adhesive prepared by using natural polymer or synthetic polymer as adhesive and water as solvent or dispersant instead of toxic organic solvents that pollute the environment.Existing water-based adhesives are not 100% solvent-free and may contain limited volatile organic compounds as additives to their water-based...
Water-based glue, when the autumn and winter season, special attention should be paid to anti-freezing treatment, according to different temperatures, the implementation of different solutions. Cautions (1) Pay attention to warmth and anti-freezing when transporting glue: when transporting below 0℃, pay attention to the warmth of the vehicle, and transport below -5℃ is prohibited; (2) Ke...
Hot melt adhesive (English name: HotGlue) is a kind of plastic adhesive, in a certain temperature range, its physical state changes with the change of temperature, but the chemical properties remain the same, its non-toxic and tasteless, belongs to environmental protection chemical products.Because the product itself is solid, easy to package, transport, storage, no solvent, no pollution, non-toxi...
The relationship between the index of laminating glue and common problems I. Viscosity Viscosity is the internal friction of the liquid, and colloquially, the thin consistency of the glue. The viscosity of the glue does not indicate the bonding performance of the glue, in other words, the thicker the glue is, the better the performance is. The viscosity can be adjusted within a cert...
Bond strength and deinking Bond strength is one of the most important indexes of glue properties. Bond strength refers to the amount of force required when the film and paper are stripped, and this index is often combined with the deinking effect. We first need to understand the principle and structure of paper-plastic composite. If you want to enhance the bonding force, you must consider the...
Anti -deformation power Anti -deformation capacity refers to a certain deformation after the composite product is affected by external forces, and this deformation will produce a certain amount of elasticity, especially the thin film. If the combination of composite is not enough to resist the elasticity of the return, foaming will occur, etc. Happening. There are many processes that produce defor...
Eight, filling The concept of filling is rarely mentioned in the application of laminating glue, but can never be ignored.The surface of the paper inevitably exists in some depression. When compounding, if the depression in the paper cannot be fully filled, it will also cause the weak. (Excellent filling effect) &nb...
Thirteen.Skinning There are two common skin phenomena: one is in the packaging bucket of glue surface skin, the other is in the glue tray surface skin. ■ The surface layer of glue in the packing bucket produces crusts 1)If the temperature of glue filtration packaging is too high, it is easy to form crust in the barrel when the temperature drops, which is common in high temperature in summer. Becau...
During December 10, 2022, customers from Russia have come to visit our company. Foreign trade manager and relevant personnel warmly welcome our customers, and introduced our product which they are interested in detailedly. Water based glue
Existing water-based adhesives are not 100% solvent-free and may contain limited volatile organic compounds as additives to their water-based media in order to control viscosity or fluidity.The advantages are mainly non-toxic, no pollution, no combustion, safe use, easy to achieve clean production technology, etc., disadvantages include slow drying speed, poor water resistance, poor fros...
Because the water glue is bonded together by the film forming principle, its compound effect is very stable, and the product can be cut immediately.If the composite quality is bad because of the process or substrate, it can also be seen in the first time off the machine, and it will not be found after mass production.Therefore, the composite packaging products use water-based glue instead of solve...
water-base adhesive With the development of society, the quality of glue has been pushed to a high point, which also led to the development of water-based glue. At present, the environmental protection industry is in a stage of rapid development. People pay more and more attention to health and environmental protection issues. The chemical glue industry is also in a stage of rapid change, and wate...
