32.1 Parallel Plate Viscometer (spreader) parallel plate viscosimeter (spread-o-meter) is an instrument that pressures the ink between two parallel plates to determine the slope, intercept, and flow values ​​of the ink spreading line. .

33 Intercept intercept refers to the difference between the spreading diameter and the slope at 10 seconds when the ink is measured with a parallel plate viscometer, which is called the intercept of the ink characteristic line.

34 Yield value yield is the minimum shear stress required to start fluid flow. More use drop stick viscometer determination.
34.1 Drop rod viscosimeter is a kind of instrument that measures the viscosity of the fluid between the rod and the sleeve during force sliding, and can measure the viscosity and yield value of the ink.

35 Thixotropy Thixotropy refers to the property of a fluid that changes in viscosity due to a forceful motion (eg, agitation) but which can be restored by standing. Cone-plate rotary viscometer.
35.1 Cone and plate viscosimeter Cone and plate viscosimeter is a sensor type viscometer consisting of a rotating vertical cone and a stationary plate. It is used to determine the rheological properties such as viscosity, thixotropy, and yield value of a fluid. 36 viscoelasticity viscoelasticity refers to the fluid's viscous and elastic properties.

37 Viscosity Viscosity refers to the force of a fluid to resist changes in its position when it flows. It is equal to the ratio of the shear stress to the shear rate, and is often coded as “η”. 38 Newtonian fluid Newtonian fluid is a fluid that can flow under very little external force. The greater the force acting on the fluid, the greater the flow rate and the proportional relationship, and the viscosity does not change due to the shear rate.

39 Plastic fluids Plastic fluids are fluids that do not flow immediately but require external forces to increase to a certain extent when subjected to external forces, and have yield and thixotropy properties.

40 Pseudo-plastic fluids pseudoplastic fluids are fluids in which the viscosity of a pseudoplastic fluid becomes thin due to the increase of the shear rate under external forces.

41 Inflatable fluid (dilatation fluid) dilatant fluid is a fluid whose viscosity increases due to the increase of shear rate under the action of external force, but it can gradually restore the original state of good flow when it is left standing.

42 Flow property is the property of the ink to change shape in response to external forces.

43 fluidity fluidity Indicated by the flow of ink in the auxiliary exhibition diameter, which is the flow of the ink.
43.1 Flowmeter The spread-o-metter is an instrument that incorporates a fixed amount of ink between two parallel round glass sheets and measures the ink spreading diameter at a fixed temperature time.
44 After the fixing setting ink is printed on the paper, the paper absorbs the thin part of the ink components, and the solid components of the paint are instantly solidified to form a back-ink film that does not pick up dirt.

44.1 printability tester printability tester Refers to the principle of printing equipment design, can set a variety of specific conditions, the ink printing performance of comprehensive testing equipment.

45 Drying Drying refers to the entire process of converting a thin layer of ink into a solid ink film.

45.1 Drying air drying refers to the process of converting a (thickness) ink into a solid film due to oxidative polymerization.
45.2 Evaporative drying drying refers to the process of solidification of a solvent-based ink from its solidified state after the solvent has evaporated.
45.3 penetration drying Refers to the process of changing the ink from a liquid state to a solid state after the liquid component penetrates into the paper.
45.4 Ultraviolet curing refers to the process by which the ink changes from a fluid state to a solid state under the irradiation of ultraviolet light.
45.5 Stoving curing refers to the process of changing the ink to a solid state under baking conditions.

46 levelling property refers to the leveling property of the ink on the substrate, showing sufficient luster without pinholes.

47 Transparence Transparence refers to the ability of an ink to reflect the color of ink covered by light.

48 Gloss gloss refers to the extent to which the ink print reflects light in the same direction under illumination. 48.1 Glossmeter The glossmeter is an instrument that has a standard light source and a variable angle measurement probe to determine the surface gloss of the test object.

49 Fineness Fineness refers to the extent to which pigments, fillers and other powdered substances in inks are finely dispersed in the binder, expressed in microns. 49.1 grind-o-meter Grind-o-meter refers to a single- or double-slot steel plate with a trapezoidal depth to determine the fineness of the ink.

50 Initial dryness Initial dryness Solvent-based ink is evaporated and dried at the specified temperature, humidity, and time using the trapezoidal groove of the Scrape Fineness Meter. It does not appear to have a groove depth for transfer printing, which is called the initial dryness of the ink.

51 Adhesion adhesion refers to the ink blot on the substrate adhesion.

52 adhesive adhesion tape adhesion refers to the use of adhesive tape stuck to the surface of the ink blot on the absorptive substrate, and then peeling, not to the extent of adhesion.
