Sankun UV curing machine analysed the composition and application of waterborne glazing oil
Flexo machine just after the printing unit, and thus can be called "light". Or operate water-based light oil, or add UV drab pieces, manipulation of the UV light oil. Also has a special polishing device for polishing, on both sides of water can also be used to adhesive coating operations, even the machine composite stickers printed products and so on. Glazing coating is more abundant than printing ink layer, in order to get better light or the rest of the efficacy.
Waterborne glazing oil secondary consists of three most main agent, solvents, additives.
In the manipulation of waterborne glazing oil or completely cancel or cut manipulation of anti-sticking agent, dirty because of waterborne glazing oil solidifying completely, the surface is very smooth, very few sticky dirty.
Monotonous life enough on the control of application of waterborne glazing oil soaked drab. Flat rate marching another step is to add the content of ethanol, but to compact the actual environment, the viscosity of the oil polish, means less arbitrary regulation.
Flexible printing of individuals are to be at the end of color series and water color printed light or UV light, are done by printing unit. Its in addition to strengthening the glory of the imprinting degrees, also is to strengthen physical surface imprinting to follow, so as to adapt to the demand, online processing after printing and packaging of goods practical begging please, and become an indispensable process.
A wide variety of aqueous film-forming resin, but now the table manipulation more throughout is trivial acrylate copolymer resin. The copolymer resin compliance depends on the monomer composition and synthetic technology. Water-borne acrylic copolymer resin has good film-forming, shining degree good, high transparency, monotonous faster, wear-resisting, water resistance and a series of exquisite compliance, a small amount of application in waterborne glazing oil.
The resolution model of paper to consider hard thick paper size and strong hardness difference tissue paper size.
Attention should be paid to the coating weight of waterborne glazing oil is not complex control, and viscosity control is more.
Waterborne glazing oil solvent times if water, colorless, boring, non-toxic, fountain, the price is low, the volatile is zero, is extremely good flowing property. However, there are not enough place, such as monotonous rate slow, complex product size not tough, etc. Thus, ethanol is added too much in control, travel in aqueous solution of drab compliance, modified waterborne glazing oil processing adaptability.
Demand point out is, a lot of packaging printing must control all the light, power products postpress begging please.
Additives. Additives for modified waterborne glazing oil physical and chemical compliance and processing. Often manipulate additives are: curing agent, surface active agent, defoamer, single swap contact, adhesion agent, wetting agent and other additives, etc.
Polishing (printed) light material varieties more equal, the resolution of light oil is marching flexo product quality a minor components.
Flexographic printing with water-based light oil and UV light oil two according to product requirements can be arbitrary resolution.
Coating process, it must be reasonable control of glazing oil viscosity and solid content, enrichment can only be carried out within a certain size of solids.
The main agent. Waterborne glazing oil is the main agent film-forming resin, the individual is a synthetic resin, its influence and at the mercy of the deep with all kinds of physical and the polishing quality of the film, such as light resistance, adhesion, monotonicity, etc.
Full version is printed by a special light light roller, rubber roller seam plate) to light. The root
There are many kinds of additives, depending on the types of oil polish on manipulation. But all kinds of auxiliary dosage should not be over 5% of the total, otherwise it will affect the gloss oil processing adaptability.
Light need to be made from all the medium, according to the part of the printing quality needs polishing.
Printed points full version printing light and the light.
The application of waterborne glazing oil, must be in accordance with the different polishing methods, the paper leads, product quality begging please appreciate the thinking ability to lose a good effect. When manipulation should be paid attention to:
Solvents. Secondary infection of the solvent is touched by contact or dissolution of synthetic resin, all kinds of additives.
To sum up, the waterborne glazing oil is theory, so the rest of the water-based materials, they are not absorbent substrates on the printing of all is not very ideal (in good absorbent paper, printing adaptability ideal), should be further improved and the other happy.
