1、 Overview
This ink is a viscous, slightly yellow fluid composed of modified epoxy resin, modified polyurethane resin, monomers, macromolecular photosensitizers, additives, etc. It is printed on paper and plastic sheets through gravure printing. The drying process is initiated by a wrinkle inducing lamp to form patterns, followed by UV curing. After printing, the product dries quickly and has a special texture. It does not contain halogens or heavy metals and has passed SGS testing, meeting EU standards. The residual content of organic harmful substances meets the national tobacco industry standards.2、 Purpose
1. Can be printed on gold and silver cardboard, laser transfer paper, PET, PVC, and corona treated PP sheets.
2. Can be used for cigarette label printing.3、 Usage method
Density is 1.02-1.10g/cm3, viscosity is 500-1500m-pas/25 ℃, gravure printing, plate depth is recommended to be 70-120 microns, the deeper the plate depth, the thicker the pattern: first pass through UV wrinkle lamps (12-20 tubes, power 40-80W can be used) to produce wrinkle effect, and then cure with 2-3 curing lamps, energy 30-75mj/cm2。4、 Precautions
1. The size of the pattern is affected by the printing thickness (plate depth). The deeper the plate depth, the thicker the pattern, and the shallower the plate depth, the finer the pattern.
2. The distance between the wrinkle inducing lamp and the curing lamp is greater than 2 meters, mainly to avoid the light generated by the curing lamp from affecting the wrinkle inducing effect of the front wrinkle inducing lamp.
3. If the wrinkle inducing lamp is close to the paper, the flower will be larger, otherwise it will be smaller.
4. Due to differences in printing environment, temperature, humidity, UV lamp intensity, and different substrates, various indicators such as explosion resistance and VOC control of printed materials are affected. When using in bulk, please test all indicators before using in bulk.
For most liquid materials, the composition information, structural information, and polarization mechanism are obtained through the precise measurement of dielectric constant eggs, which has recently become more and more popular than optical-based spectral egg characterization. Especially for natural mixtures, such as milk, fruit juice, grains and some soft tissues, the advantages of permittivity characterization are more prominent.
SiP-level package products based on domestic DDR3 die with a package size of 8.5mm x 10mm. The electrical characteristics of the product meet the JESD79-3F DDR3 SDRAM standard. Two 16-bit DDR3/3L bare chips, terminating resistors and capacitors are internally sealed to form a 32-bit memory chip. The product design conforms to industrial standards and can be widely used in data caching and data processing.
