Ink Introduction

Ink is a material that reproduces and fixes characters and patterns of a manuscript on the surface of paper, plastic, metal, glass, wood, rubber, and fabric by means of various printing means.

Printing ink cartridges have vivid colors, good printing performance, sufficient drying and fixing speed. In addition, the ink must have sufficient stability to acids, alkalis, water, various solvents, soaps, light, heat, oil, and the like.

Traditionally, it is divided into paper printing inks, plastic inks, newspaper printing inks, glass inks, and hose oil inks. The certain printability of the ink determines the type and use of the ink.

(1) Connection materials Such as ink transfer ink, which is the fluid part of the ink, acts as a bonding, wetting, dispersing, etc. in the ink, giving the printability of the ink one, and determines the type of ink and the method of use.

The raw materials for making the binders are mainly oils, natural resins, synthetic resins, and various solvents.

(2) Colorants are various organic pigments, inorganic pigments and a small amount of dyes. Its main function is to color the ink, it is insoluble in water, and it is also insoluble in the oil or colored material of the binder. Because it has enough fineness, evenly dispersed in the connecting material, so that the ink shows colorful colors, to a large extent affect the ink's vividness, printability.

The colorant occupies a large proportion in the cost of ink, accounting for about 60% of the total cost of the ink, the quality of the objective existence is good or bad, the level of concentration often affects the value of the ink.

(3) Filler materials such as colloidal calcium carbonate, barium sulfate and aluminum barium bethune and other easily dispersible powders, should be used as pigment fillers in the ink, the main role is to adjust or reduce the cost of ink, adjust the ink dilute, and other physics Indicators and ink, adjust the ink concentration to dilute.

(4) Auxiliary materials such as cobalt naphthalate, manganese borate and other driers, eugenol and other dry inhibitors, polyethylene wax and other abrasives and detackifiers, naphthalene anti-gel naphthalene polish agent.
