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 ...
1.After besmear brushes its film sex is good, the surface after coating solidifies can form uniform rubber shape elastomer, and this kind of coating suits special-shaped structure very much. 3.It is very convenient when construction, suit any besmear to brush means, be it wet surface also can construct. 4.Coating itself is absolutely environmental protection, non-toxic without any smell, the use o...
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...
Waterborne polyurethane is often used in the preparation of waterborne coatings because of its excellent film formation and adhesion, excellent flexibility and wear resistance.However, water-based polyurethane dispersion contains a lot of surfactant, easy to produce bubbles, and because of the special properties of water-based polyurethane, it is necessary to use the characteristics of water-based...
Waterborne Acrylic Resin Product Description: The water-based acrylic resin is made of acrylic acid and acrylate monomer through solution polymerization. Product purpose: This product can be used for water-based aluminum foil gloss and ink, water-based gravure printing paper gloss and ink, water-based carton ink manufacturing Product features:alcohol water as the main solvent, has no smell, no tox...
Water-based ink is composed of resin (water-soluble resin colloidal dispersion emulsion polymer) aqueous amine (mainly ammonia) pigment (organic pigment inorganic pigment) and additives.The so-called water-based ink is mainly water as a solvent by scientific processing, compared with other printing ink, water-based ink, because it does not contain volatile toxic organic solvents, so in the printin...
