ASTM D5909-1996a用角鲨烯抗氧化剂干燥氧化 - 干燥印刷油墨的时间的标准试验方法

1.1 This test method covers the procedure for determining the drying time of oxidative-drying printing inks (also referred to as "sheetfed inks") by squalene resistance of printed ink films. 1.2 This test method is applicable to all paste inks that dry primarily by oxidation regardless of the substrate on which they are printed. With appropriate changes in the test fluid, it may also be used with paste inks that dry by other mechanisms, such as heatset or ultraviolet light. 1.3 This test method utilizes a modified rub tester and is intended to serve as a "referee" procedure when laboratories, using less rigorous test procedures (see Appendix X1), cannot agree on their results. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

ASTM D5909-1996a(2006)用角鲨烯抗性测试氧化物干燥印刷油墨干燥时间的标准试验方法

Inadequate setting or drying of sheetfed inks, or both, can cause blocking of stacked prints with subsequent loss of product. x201C; Settingx201D; of an ink refers to the rapid rise in viscosity of the printed ink film, sometimes accompanied by surface drying, that prevents transference of the undried ink film to adjacent surfaces under light pressure. x201C; Settingx201D; is a property of the ink-substrate combination. Inadequate drying may be due to several factors, but the primary causes are: (1) omission of metallic driers from the ink, improper ink formulation (2) unusual ink-substrate interactions, and (3) use of a fountain solution that is too acidic. If the test prints are made on a standard laboratory proof press, where there is no application of fountain solution, then only the first three possible causes can be evaluated. If the prints have been made on a commercial production printing press or some other acceptable means of introducing the fountain solution into the ink agreed upon, then the effect of fountain solution can be determined. It will often be necessary to run several tests to isolate the specific cause of a drying problem. This test method is suitable for most combinations of oxidative drying inks and substrates. Because this test method relies on a visual assessment of the extent of drying, very light colors and clear varnishes may present difficulties in quantifying the extent of drying. In such cases, the supplier and the customer should agree upon an alternative method of assessing the drying properties of the ink.1.1 This test method covers the procedure for determining the drying time of oxidative-drying printing inks (also referred to as "sheetfed inks") by squalene resistance of printed ink films.1.2 This test method is applicable to all paste inks that dry primarily by oxidation regardless of the substrate on which they are printed.
