printing ink, is an important material used for printing. It displays patterns and words on the substrate through printing. Ink contains the main components and auxiliary components, they are evenly mixed and repeatedly rolled into a viscous colloidal fluid. Consists of linkers (resins), pigments, fillers, auxiliaries and solvents.
Ink has a lot of types, physical properties are not the same, some very thick, very sticky, some very thin. Its components can be divided into three major parts: liquid components are called linkers; solid components are colorants (pigments or dyes) and various additives. Different ink drying method is also different; Different printing processes use different inks; Different substrate materials use different inks.
Plate type classification
Letterpress ink; 2. Lithographic ink; 3. Gravure ink; 4. Mesh printing ink.
Classification by solvent
1.Water-based ink; 2. Uv curing ink; 3. Water-based UV ink.
In addition, in flexo printing, alcohol soluble ink as playing main role is also a very small pollution of the ink, mainly used in food, drugs, beverages, tobacco and alcohol and the daily necessities, packaging printing and other aspects.
III. Ink complete set
1.Eight production line systems:Powder and liquid feeding system; Pulping system; Paint adjusting, material discharging and filtration system; Filling system; Cooling system; Piping system; Electrical control system; Operation platform,
Complete set of automatic ink equipment,High intelligence, high efficiency, super - fine superior performance. Suitable for mass production; The designed annual output can range from 500 tons to 50,000 tons. Different configuration can be provided according to process and output; The equipment can independently complete the whole process of vacuum feeding, dispersing, grinding and refining, cooling, paint mixing, filtration and semi-automatic filling. High degree of automation, safety, economic, environmental protection.
(1)powder and liquid feeding system: pneumatic powder conveying, screw conveying and liquid conveying system.
(2)coating dispersing machine, realizing pre-dispersing, stirring, high speed dispersing, adjusting paint, adjusting color, having good adaptability to medium and high viscosity and thixotropic materials, especially high speed and fast for mass production.
(3)grinding machine, is a wet grinding equipment, suitable for coating, ink, pigment, color paste, cosmetics, pesticides, medicine and other industries with high fineness requirements.
(4)paint kettle, the agitator for the paint kettle can be made into paddle type, frame type, anchor type, etc., generally running at a low speed.
(5) filling machine, mainly a small category of filling machine products, from the degree of automation, it can divide into semi-automatic filling machine and automatic filling production line. According to the nature of filling materials, there are explosion-proof filling machine and ordinary filling machine.
