UV multicolor screen printing machine Product description:
UV multicolor screen printing machine is the most innovative new generation of screen printing press at home and abroad, leading technology, the world's first. The machine set machine, electricity, gas, light in body, digitized the entire computer automatic control, smooth operation of the high-speed, accurate positioning, successfully resolved the difficult dry ink, multi-color continuous printing can not in one step, low efficiency, poor adhesion material, printing the effect is not ideal UV printing common problems. This device is particularly suitable for smoke package, box, metal, soft, hard plastic sheet (such as PVC, PP, PC, PET, EVA, APET, PETG), plastic leather, wood, glass, ceramics, cardboard and other hard precision brittle materials and other such as clothing, Pibu category (nylon cloth, Trinidad and Tobago Long, Michael Liu, satin material, PVC leather, PU leather) and other special sheet of continuous color printing.
The equipment has a number of utility model and customize design patents, the indicators have reached the international advanced level, product complies with European CE safety standards, Zhejiang Province industrial new products.
UV oven working principle and characteristics:
A, UV curing principle:
Adding a specially formulated resin in photoinitiator (or photosensitizer), through the absorption of ultraviolet (UV) light curing equipment after the high-strength UV light, generate reactive free radicals, thereby initiating polymerization, crosslinking and grafting reaction, the resin The ink / paint in less than one second of time by the liquid into a solid.
Two, UV curing lamp:
1. Current UV light source device used in the industry, mainly gas discharge lamp. According to the size of the lamp lumen pressure gas into low, medium, high pressure, high pressure several Division I use a high-pressure lamp.
2. The high-voltage lights can produce intense radiation 310nm, 365nm, 410nm wavelength and other characteristics of ultraviolet light (UV), visible and infrared light (IR), wherein the main peak of 365nm wavelength band is commonly used around the world for curing dry bath of (the title refers to the high-pressure mercury lamp UV lamp of 365nm). Since 365nm spectral band is suitable for conventional light-cured ink / paint, so the choice is generally UV light curing equipment when it is necessary to carry out light curing tests to verify wavelength UV light solid machine meets the requirements.
3.UV reasonable refraction of light and the stray light filter UV lamp is very important, otherwise it will affect the curing effect.
4. General UV machine solid ink / paint required power 80-120w / cm, the light energy is too high can cause solid ink / paint embrittlement, solid low energy light can not reach the light solid results.
5.UV UV lamp in sporadic, it would also generate a lot of heat, so that the body temperature continues to rise, so the top of the UV lamp light aircraft equipped with ventilation means it is necessary, and through the ventilation duct The ozone generated during the curing exhausted to the outside to achieve the purpose of cooling, the coating is too thin to accommodate work or work requiring high temperature ..
Third, the main features of our UV oven:
1. oven overall mobile work, beautiful appearance, small and lightweight, space-saving.
2. Optional lamp power professional, the use of imported light reflector, the maximum UV light refraction.
3. Quartz glass filters can be fitted with a special filter more stray light, and coupled with advanced ventilation cooling device, ensure that the workpiece is not temperature, successfully resolved the difficult dry ink paint, material adhesion is poor, inefficient Printing effect is not ideal UV printing common problems, enhance drying curing effect.
