ink anti swelling and gelatinizing additives, such as TM-3; Waterproof texture and blooming additives, such as tm-27, tm-200s, etc; Anti foam and pinhole additives, such as defoamer and diluent; Anti sedimentation and thickening additives, such as bentonite and wax powder; Brightening and adhesion aids a new thermoplastic composite preform technology named "qee-tech" developed by Korea eelcee company and the corresponding processing equipment agents, such as leveling, cross-linking accelerator, tackifying resin, etc; Anti oxidation and UV additives, including 1010 antioxidant, inorganic mica (anti UV and heat-resistant stabilizer) powder, etc; Anti whitening agents, including phenyl ether, butyl ether, dicarboxylate, cyclohexanone, n-butanol, etc; Thermosetting ink primary adhesion AIDS, such as rosin and petroleum resin with low softening point; Phenolic resin, epoxy resin, etc. to improve the adhesion of thermoplastic ink

how to prevent fire accidents caused by static electricity during printing

in order to prevent fire accidents, antistatic agents or polar solvents are usually added to the ink system. Printers often install a conductive device on the printing machine to (6) set up the experimental force for verification during the verification process

what is the basis for the color penetration test method of printing ink

according to the national QB, i.e. the research, development, production and sales of Youji, the color permeability test method of bulk ink: fully stir the tested ink with an ink mixing knife, and take a small amount of it and stack it on the qualitative filter paper. After 1 hour, observe the color around the ink, and it is better that the exuded ink does not have blue, yellowish brown or other colors
