Diethylenglykoldiethylether diethylene glycol diethyl ether. As far as known, has yet been used a ternary or quaternary mixture for measurement of the surface tension.
DE DEU1 en Test xin according to any one of the preceding claims, characterized in that it comprises as a first component at least one polyglycol ethers, in dkn dipropylene glycol monomethyl ether, and as a second component at least one pyrrolidone, in particular N-methyl-pyrrolidone. Further, substances from the group of organic dinitriles or trinitriles, di- or Tricyanoverbindungen are usable called, preferably bis cyano ethyl ether, dicyanobutene or Glutaronitrile.
The newly developed test inks show no change within the usual processing times of several months. Ein Vergleich der Mischungen. In addition to said test inks with components and test inks are quite possible, which have more than 4, especially 5, components.
The polarity of these clear fluids is zero. 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. The mentioned in the tables percentages are consistently in order volume.
Use according to one of the preceding claims, characterised in that an additional, more especially second, component is at least one substance from the group of pyrrols, pyrrolidines or pyrrolidones, preferably N-methyl pyrrolidone, or one substance from the group of organic dinitriles or trinitriles, preferably bis- cyanoethyl etherdicyanobutene or a glutaronitrile.
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. MC Free format text: Starting from this prior art, the present invention has for its object to provide a test ink, which overcomes the mentioned disadvantages. The surface tension or the specific surface energy is the amount of energy that must be applied in order to increase the surface of a liquid or a solid to a certain extent.
IT Free format text: Sie ist chemisch stabil und reagiert nicht mit sich selbst oder mit Wasser. Use according to one of the preceding claims, characterised in that an additional, more especially fourth, component is water. Test ink from at least two components of different surface tension, in particular for applying to workpieces to determine the surface properties thereof, wherein the test ink is substantially free of substances subject to identification.
Test inks are used in accordance with DIN usually. Carrier materials containing polymer-bound fillers, process for their manufacture and their use. This means what was not expected from theory that other factors than the surface tension affect the degree of wetting of the surface.
Test Inks and Test Pens | For testing the surface tension
The following ternary mixture as a further example in reference to the comparison with the DIN inks very good results. Sealing wooden floors – by applying filler compsn. The wording of all claims is hereby incorporated by reference into the description.
Um Zulassungsverfahren zu vermeiden bzw. Methoxypentanol and diethylene glycol have similar viscosities of about 35 mPa s, so that mixtures show approximately similar values. Sie eignet sich hervorragend bei einem Temperaturbereich von ca.
IT Free format text: Because of the formamide content, these mixtures are classified as poisonous. Inks of this value are in demand because of this. PLFP Year of fee payment: The degree to which the fluids are toxic is a factor of the methanol content.
Anticorrosion coating composition for steel, especially for reinforcement steel in concrete. Aqueous impregnating resin bath for production of impregnating resin film and laminates, contains melamine-formaldehyde resin, hardener and a quaternary ammonium compound with long-chain alkyl groups as antistatic agent. For example, to adhere the surface with paint or adhesive, dim to be able to wet permanently, the surface of the substrate chemically for example with primers or physically for example by gas flame is pretreated by changing the surface energy of the substrate.
Use according to one of the preceding claims, characterised in that an additional, more especially third, component is at least one polyalcohol, with the exception of ethylene glycol, preferably glycerin or diethylene glycol or triethanol amine.
Since the rate of contraction is a predominantly dynamic property of materials will contract faster with a lower viscosity than those which have a greater viscosity.
