Thermosetting plastics, also known as ink printing ink, or
Adhesive Ink. Which contains components: mainly polyvinyl chloride (PVC) and phthalate esters composition, the PVC and phthalates, fixing agent, stabilizer, thickening agent a mixture of thermosetting ink .
Plastisol ink non-solvent based ink, he is by heating, the powder dissolves plastics and additives penetrate between the fibers and fabrics firm membrane adhesion formation closely. Since the restrictions now ban the use of PVC, PVC can be replaced by a modified body, to make consistent
Environmental protection Requirements of plastisol ink. PVC plastics because the temperature difference, hot ink can be divided into two categories of high and low temperature.
Plastisol ink to enter the market early, but the operation of the strange and equipment limitations, to promote the relatively slow speed, and now from its marketing to production runs have been very mature.
Basic requirements of thermosetting ink Do not use polyester board hard board, and Taiwan should use a hard type board, tempered glass is now more common, according to the use of screen
Print Flexible application design. Such as: proposals for the transition fine network of 150 mesh ~ 250 mesh screen between the more appropriate, heat sensitive plastic solid ink itself is not required. General
Printing Patterns proposed use of water, oil dual-use type. This rub boards, whether in water or solvent can be used.
Three-dimensional thick-film prints To use special thick board, made of thick-film photoresist? Screen 1 in the normal thickness of the coating, the thickness of external design with a round under a complete knife coating or multiple coating with common after sizing device, placed inside the 40,50,60 minutes drying bake version can be exposure. Because of photosensitive plastic boxes of different power and exposure time of exposure is not the same as it must do test. Imaging must be placed after the low-temperature drying water drying Edition box. Do not dry in the sun exposure. Thermal performance of solid ink temperature is a key feature. It is therefore recommended drying heating equipment, good insulation, heating temperature of stability.
Special additives plastisol ink Plastisol ink is a very independent printing materials. She has its own dedicated printing auxiliaries. Such as: diluent, thickener, softener, such as fixing agent. If encountered during operational use by many to add additives, it is recommended the first contact with the producers. After listening to recommendations to operate. Do not arbitrarily add and subtract based on experience additives and unnecessary wastage and loss.
Hot solid ink technology Plastisol ink printing results according to different process is divided into general and special categories.
Ordinary printing process refers to simple, solid, line of monochrome Color Printing. Such process in addition to heating, the ordinary printing process is exactly the same. Simple, no clean plates, plastics, printing material than the properties of water are several times higher.
Special printing process refers to three-dimensional printing, foam printing, flock printing, gravel surface printing, printing and Roberts.
A good grasp of the curing temperature curing ink
Most of the failures and the reason is not a good grasp of curing temperature and time. Ordinary prints, curing generally need 170? 180 bank to set up specialized? Minutes. Special prints, curing generally require pre-drying at 100? 30 seconds into the drying tunnel surface after drying dryer 170? 180? -2 Minutes. (White face cloth easy to change color temperature, the temperature appropriate to reduce the time extension) other: plastisol ink foaming machine for foaming pressure hot the surface is smooth.
Plastisol ink common problem during the operation
1. Ink drawing is not clean ... clean up ... if not add thinner viscosity, 1% can be
2. ... ... Back to the missing pattern knife edge too much, or too thin ink
3. Thick film or surface patterns in bubble ... ... curing temperature is not high enough or long enough
4. Pattern matte, no tension, in powder form off, there is no cure
5. Overheated after the ink color, fabric color sublimation ink absorption after the traction has been recommended for pre-press sample test, if the fabric color easy to sublimate the need to use anti-sublimation thermal solid ink.
6. Waterborne thermosetting glue and printing ink overlay each other, but the water slurry can be printed on thermal solid-ink cover
7. Waterborne printing color types of ink can not be mixed with thermosetting
8. Plastisol ink is not universal ink, fabric of different materials should be used accordingly thermosetting ink
9. Climate, environmental change will affect the viscosity of thermosetting ink can add thinners or thickeners as needed I am a professional writer from China Crafts Suppliers, which contains a great deal of information about 10kw diesel generator , residential diesel generator, welcome to visit!
