Photo sensitive aluminum CTP plate

 

The production process of the photo sensitive aluminum CTP plate base is mainly studied for the grit treatment and anodizing treatment involved. When the grit treatment, the surface roughening method, the concentration of hydrochloric acid, the temperature of the electrolyte and other factors are investigated. The influence on the effect of sand meshing treatment is obtained, and the appropriate process conditions are obtained. The concentration of hydrochloric acid is 8-10 g/L, and the temperature of the electrolyte is 30-60℃. During anodizing, the concentration of sulfuric acid, the temperature of the Oxidation time and the influence of impurities in the oxidizing solution on the effect of anodic oxidation, to obtain suitable process conditions, the sulfuric acid concentration range is 15%-30%, the oxidation solution temperature range is 25-30℃, and the oxidation time range is 40-60s. The concentration of aluminum ion in the liquid ranges from 0.5% to 5%.

The advanced photo sensitive aluminum CTP plate photosensitive layer formula system was analyzed, and a new photosensitive layer formula was proposed. By studying the influence of the acid value, iodine value, molecular weight, etc. of the film-forming resin in the photosensitive layer on the printing quality, the appropriate resin acid value range is 48-53 (mgKOH/g), and the iodine value range is 25-30g/ 100gI2, the molecular weight ranges from 62725 to 64980. The effects of sensitizing dyes, initiators, and monomer functional groups on the sensitivity of the photosensitive CTP plate were studied. The monomer percentage ranges from 4.0 to 5.0%. The influence of the amount of prepolymer, the amount of polymerization inhibitor, and the water-soluble filter dye on the printing quality is studied, and the appropriate percentage of prepolymer is 3.2%, and the content of polymerization inhibitor should preferably be greater than or equal to 0.2% .


On the basis of the above research, the photo sensitive aluminum CTP plate prepared according to the new process formula, after performance testing and application evaluation, the plate can fully meet the requirements of users and has good application value.

Differences between PS and CTP base plate

图片
With the increasing maturity and the rapid development of CTP technology, as well as the declining of price, CTP technology has been more and more welcomed by the majority of printing practitioners, usage of CTP plates have the potential trend to catch up with the traditional PS plate. The overall requirements of the printing plate is very high, especially the current CTP plate is mostly used for high-grade color printing plate, to ensure the quality of the plate, the plate based apparent quality is the premise. The characteristic of CTP technology is the quality of CTP based plate, such as the apparent quality, physical property and electrolytic performance. The aluminum plate base is widely used according to CTP plate technical requirement. The difference between CTP plates and PS plate on the apparent properties of aluminum plate base are as follows. The basic appearance requirements of the aluminum base plate is clean and smooth, no cracks, corrosion pits, air vents, scratches,...

Introduction of aluminum foil insulation material

图片
Aluminum foil insulation material is the best thermal insulation material at present in the world. It has the advantages of light weight, low thermal conductivity, good heat resistance, aging resistance, easy combustion with other substrates, bonding does not produce droplet and other excellent properties. On the application, it is widely used in building roofing, wall, ceiling, floor, doors and windows as insulation materials. Aluminum foil itself is a good conductor of heat, directly used basically has no heat insulation, but accelerate the heat loss, so when used the insulation cotton is wrapped inside the aluminum foil . It has the functions of heat insulation, waterproof, moisture-proof and so on. Its solar radiation absorption coefficient is very low, which can insulate most of the heat transfer. Introduction of advantages of aluminum foil insulation material: (1) Simplification of structure to avoid waste. (2) It is unnecessary to set roof exhaust system. (3) Waterproof lay...
