摘要:
A web offset heatset printing ink composition having less than about 2 wt. % of volatile organic compounds containing an aqueous polymer latex dispersed in an ink base of a resin, a non-volatile plasticizer, and a pigment and method for preparing same.
摘要:
A water washable lithographic printing ink composition containing a rosin-based resin, an alcohol solvent, a pigment, an acid neutralizing agent, a plasticizer, and a thermoplastic latex emulsion.
摘要:
Disclosed is a water washable ink for offset lithographic newspaper printing containing: a modified soybean oil-based resin; a pigment; and an acid neutralization agent, wherein the water washable offset lithographic newspaper printing ink does not contain any of the following: a humectant, a surfactant or a modified linseed oil.
摘要:
Solvent-based flexographic or rotogravure inks are formulated to provide good pin-holing performance at high-speed printing conditions by combining the ink ingredients such the Maron-Pierce MPF (Maximum Packing Fraction) of the resulting ink is below 42 volume percent at a shear of either 10 reciprocal seconds or 2100 reciprocal seconds or both.
摘要:
Formulations for solvent-based flexographic or rotogravure inks, which are capable high-quality, defect-free printing at high speeds, contain flexographic ink resins solutions and solvent mixtures which are designed to maintain a dynamic solubility parameter in the ink as the dry state is approached during the printing process. The inks described show extremely high quality printing at linear press speeds above 1800 fee per minute (ca 0.549 km/min).

摘要:
This invention involves a warhead, for use against armor containing several reactive stages, specifically, an anti-tank warhead, of a type comprising shape charges acting sequentially from front to rear and separated by protective elements. It includes:a front module containing at least two tandem-mounted shape charges (1, 2) whose caliber is between 25 and 50% of the caliber of the warhead, with a delay of 100 to 500 microseconds between their respective initiations; anda main charge (3) whose caliber is the same as that of the warhead and which is initiated after a delay of 200 to 2000 microseconds after initiation of the rear charge in the front module.Applications involve shells, rockets or missiles intended to attack multi-stage, spaced, composite or reactive armor.
