The test inks are added in small amounts on a regular basis for visualization dyes.
Test ink according to any one of the preceding claims, 533644 in that it comprises as a first component at least one polyglycol ethers, in particular dipropylene glycol monomethyl ether, and as a second component at least one pyrrolidone, in particular N-methyl-pyrrolidone. Test ink according to claim 1, characterized in dinn the test ink has at least three, preferably at least four, components. Adestor Today Why choose us?
This testing procedure provides for the utilisation of a standardised blue test ink for all tests according to DIN Test ink according to claim 6, characterized in that an additional, more especially second, 5336 N-methyl-pyrrolidone. This object is inventively achieved by a test ink having the features of claim 1. Roll products Sheet products Components Certificates Packaging and service.
An attempt has already been done to sell at least somewhat safer test inks vin a toxicological point of view. To category Toner Powder. Methoxypentanol and diethylene glycol have similar viscosities of about 35 mPa s, so that mixtures show approximately similar values. Anionic tensides with a content of decomposed protein, their production and application.
I have read the data protection information.
Adestor :: PE Transparent µm / A / WG62 product sheet
Anticorrosion coating composition for steel, especially for reinforcement steel in concrete. FG4D Free format text: DK Ref legal event code: The mentioned in the tables percentages are consistently to volume. A2 Designated state s: The following ternary mixture as a further example in reference to the comparison with the DIN inks very good results. Delivery time 2 Workdays. IE Free format text: Use of non-hazardous materials to prepare a test ink comprising at least two components of different surface tension, in particular for applying to workpieces to determine the surface properties thereof, in particular the substances mentioned in claims 4 to 14 are used.
Test ink according to any one of the preceding claims, characterized in that an additional, more especially third, component is at least one polyalcohol, preferably glycerol or diethylene glycol or triethanolamine. At the time of the DIN standard all the toxic properties of these substances were not known. Test ink according to any one of the preceding claims, characterized in that a first component having a lower surface tension value dipropylene glycol monomethyl ether or diethylene glycol diethyl ether is.
IE Ref legal event code: Liner WG62 Super-calendered translucent glassine paper especially designed for automatic labelling applications and photocell dispensing systems. Test ink according to any one of the preceding claims, characterized in that a first component is a diglycol ether, a second component N-methyl pyrrolidone, a third component is glycerol and a fourth component is water.
However, both materials are considerably more viscous than the starting materials of the DIN inks so that these inks contract slower than that.
Notes Values are subject to change without notice. I have read the datapolicy understand it and agree. Read, write and discuss reviews Year of fee payment: The surface tension is correlated similar to the viscosity with the inner attraction forces of a substance. Technical information Current news. The newly developed test inks show no change within the usual processing dun of several months.
Bis cyanoethyl ether Bis cyanoethyl ether.
Test ink for application to a workpiece to determine its surface characteristics. It has almost identical or similar behavior as the DIN-inks in terms of speed of contraction and the wetting resistance. PLFP Year of fee payment: Test ink according to any one of the preceding claims, characterized in that an additional, more especially third, component is triethanol amine.
Ref legal event code: Test ink according to any one of the preceding claims, characterized in that an additional, more especially second, component is at least one substance from the group of the pyrroles, pyrrolidines or pyrrolidones. The surface tension or the specific surface energy 5336 the amount of energy that must be applied in order to increase the surface of a liquid or a solid to a certain extent.
Set of 8 PINK pens 30 to 44 dyne/cm
As far as known, has yet been used a ternary or quaternary mixture for measurement dni the surface tension. This is mainly to electrostatic attractive forces, dipole and Van der Vaals interactions. Test ink Afor application to a work piece to determine its surface properties, in which the surface tension ST is adjusted by mixing at least two base components B having different values of ST, to provide a mixture with an intermediate value for ST.
Download adhesive product sheet.
Test ink according to any one of the preceding claims, characterized in that an additional, more especially second, component is at least one substance from the group of organic dinitriles or trinitriles, preferably bis cyano – – is ethyl ether, dicyanobutene or a glutaronitrile. To determine the surface tension of a solid, the contact angle method is usually used.
Kind code of ref document: For comparative studies DIN inks and the newly developed inks are applied to different plastics simultaneously. In addition to said test inks with components and test inks are quite possible, which have more than 4, especially 5, components.
