Water - based ink is composed of adhesives pigment additives and other substances such as uniform slurry material,Binders provide ink with the necessary transfer properties, pigments give ink color. Water-based ink linker is mainly divided into two types: water dilution and water dispersion.The former can be used in many types of resin, such as maleic acid resin lac maleic acid resin modified shel...
Flexo printing ink characteristics: 1 Water-based ink (mainly used for paper printing) Water-based ink is the biggest characteristic, the use of water-soluble or water-dispersive resin as a linker, reduce the discharge of organic volatile matter, it can completely eliminate some toxic substances to the human body and the pollution of packaging goods.Water-based ink makes less investment in environ...
With the improvement of social progress and people's awareness of environmental protection, water-based ink in the field of packaging printing ink has attracted much attention.Water-based ink is more widely used in the fields of paper, food, medicine, packaging and printing because it has very low organic volatile matter (VOCs) and green environmental protection. However, in the field of gravure p...
Water-based adhesives are environmentally friendly adhesives made of natural or synthetic macromolecule as adhesives 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 vocs as additives for their aqueous media in order to control viscosity or fluidity.Advantages are mainl...
Water-based ink resin is the carrier of pigment in ink, is the core material of ink, its quality, will directly affect the performance of ink, because water-based ink resin to a large extent determines the viscosity of ink, dry fluidity and other properties.Anti - viscosity is an important physical property index of printing ink.Intaglio printing is a kind of printing with high order ink supply, g...
In recent years, China's food packaging industry has developed rapidly, and the consumption of ink printing has increased significantly. With the continuous progress of China's industrialization in breadth and depth, various environmental and food safety problems have become prominent.The field of flexible packaging, especially as the food packaging industry involved in the estimated contact with ...
After toning water-based plastic composite ink is used, there is often error with the standard color, which is difficult to completely avoid the problem, can only be reduced to a low limit. Different printing ink factory use of the same part of the printing machine, different printing machine mesh mesh line number Angle has a big difference, which makes the same ink, in different printing methods ...
Acrylic pressure sensitive adhesive is a large range, PUR is one of them, most of the acrylic pressure sensitive adhesive is heated operation, can be reheated after bonding, is reversible.And PUR is wet reaction acrylic pressure sensitive adhesive, heating operation, after bonding and moisture in the air reaction, after the reaction is irreversible (that is, heating will not melt). So PUR is more ...
Adhesives with water (inorganic solvent) as the solvent/carrier are called water-based glues, solute (glue) can be dissolved in water/or dispersed in water,Water-based glue can be miscible and dispersed in water, diluent is water. Adhesives with organic solvents as solvents/carriers are called oil-based adhesives (solvent-based adhesives). Oil-based adhesives are not soluble in water and cannot be...
◆ The procedure of bonding process:◆ The adhesive surface should be evenly coated to ensure infiltration, as far as possible to avoid bubbles, due to the porosity of the adhesive strength greatly reduced, resulting in degumming.Attention should be paid to the alignment of the position, not staggered, can be pressurized, air exclusion, make it close contact. Time is three important parameters of cu...
The chemical composition of glue, the polymer in the water environment glue (vinyl acetate in white glue is a kind of petroleum derivatives) are round particles, the radius of the general particle is between 0.5~5μm.The bonding of objects is achieved by the tension between the polymers in the glue.In the glue, water is the carrier of the polymer, and the water carries the polymer slowly into ...
As the composition of waterborne UV curing ink china-africa photosensitivity, pigment and absorb UV light initiator competition, to a great extent, it affected the curing characteristics of the UV curing system in the system Due to the pigments can absorb part of the radiation energy, it will affect the light initiator for the absorption of light, and, in turn, affect the ability to gene...
Composition of pressure sensitive tape 1.Pressure sensitive adhesive, 2.substrate 3.Primer 4.Back treatment agent 5.Isolation paper The main components of the pressure sensitive adhesive and resin, including rubber such as polyacrylic acid ester or polyvinyl ether, homogeneous base material requirements, small scale and good to solvent invasive, including, (1) fabric such as cotton, glass cloth or...
As we all know, with the development of society, people attach importance to food safety and so on, label printing is greatly encouraged, and label has become comparable to packaging. The development of label has driven the development of label printing, and ink is the main medicine in label printing,In the field of label printing, ink can be generally divided into three categories, namely: water-...
(1)The labels on the market (especially film labels) mostly use screen printing and flexographic printing, which not only has a complex processing process, a long cycle, but also has poor timeliness. (2)In terms of product design, the selection of design scheme needs to be modified repeatedly, which is not only troublesome, but also costly (3)The traditional printing method to achieve variable dat...
The bonding effect can be achieved by applying pressure for a short time (non-aqueous solvent heating) It overcomes the solvent volatilization and drying time needed during the operation of structural adhesive, and can improve the working environment After stripping, it can be corrected without contamination and can be reused for many times Easy to operate, can greatly improve the production effic...
