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...
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...
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...
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...
Classification and characteristics of screen-printable pressure sensitive adhesives I.Characteristics and performance requirements of screen printing process Screen printing is through a certain pressure to make the printing base material through the holes of the plate to the substrate, the formation of an image or text. In order to achieve good printing adaptability, the physical properties of sc...
Classification and characteristics of screen-printable pressure sensitive adhesives Ⅱ Classification of screen-printable pressure sensitive adhesives Because of the simple screen printing equipment, convenient operation, simple printing, plate making and low cost, for the application of coating pressure sensitive adhesive, also often consider the use of screen printing process to coating.The ...
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 polyurethane is a kind of block copolymer containing soft segment and hard segment. The soft segment is composed of oligomer polyols, and the hard segment is composed of polyisocyanate and chain extender. It has excellent wear resistance, oil resistance, low temperature resistance, aging resistance and chemical resistance.At present, the water based polyurethane emulsion on the market ...
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...
