摘要:
A method is provided for detecting not fully set coatings and liquid or smearing impurities on a surface, in which in a first step a film is pressed onto a surface of a coating using a predefined press-on pressure, the film having a relative motion with respect to the surface of the coating, thereafter the film is pulled off the surface of the coating and finally it is determined whether impurities are adhering to the film. A device is also provided for performing the method, including at least one film, which may be pressed against a surface to be tested, at least one press-on roller having a surface by which the film is pressed against the coating, and at least one device for determining whether there are impurities adhering to the film.

The invention relates to preparations, in particular plant-protective preparations which contain a mixture of at least two different active plant-protective substances, wherein a) at least one active substance is selected from a conazole group (active substance 1) and b) another active plant-protective substance (active substance 2) whose water solubility at a temperature of 20° C. is less than 20 g/l, c) at least one type of copolymer CP consisting of M monomers comprising α) at least one type of monoethylenically unsaturated monomer M1 comprising at least one sulphonic acid group and β) at least one type of neutral monoethylenically unsaturated monomer M2, wherein the quantitative ratio between the active substance 1 and the other active plant-protective substance 2 ranges from 1:10 to 10:1. Said invention also relates to novel copolymers CP which are embodied in the form of polymers consisting of at least three types of different monoethylenically unsaturated monomers M and comprise, in the polymerisation incorporated form, α) at least one type of monoethylenically unsaturated monomer M1 comprising at least one sulphonic acid group, β1) at least one type of neutral monoethylenically unsaturated monomer M2 whose water solubility at a temperature of 20° C. is less than 30 g/l and β2) at least one type of neutral monoethylenically unsaturated monomer M2b whose water solubility at a temperature of 20° C. is greater than 50 g/l.

The present invention relates to an apparatus for the simultaneous analysis of at least two samples by the field-flow fractionation method, where the apparatus has at least the following elements: a) a source of a defined liquid stream, preferably a pump, b) at least two separation channels, each with at least one inlet and each with at least one outlet for passing the at least two samples through in each case one of the at least two separation channels, c) at least one controllable unit which is connected to the at least two separation channels via their at least one outlet each, and which can pass on the at least two samples, which can be passed through in each case one of the at least two separation channels, separately from one another to at least one unit downstream of the controllable unit.
摘要:
A description is given of a method of crosslinking radiation-crosslinkable pressure-sensitive adhesive films by controlled-dose exposure to actinic radiation, which involves exposing the film surface to a regular or irregular radiation pattern made up of regions of different intensity. The method permits a more precise adjustment of the adhesion—in particular, the adhesion of flexible films on a substrate.
摘要:
A method and an apparatus for determining diffusion parameters, concentration, size or flow behavior of particles in a sample, exciting light of a light source being directed into the sample, Raman scattered light being collected from an observed volume of the sample and being passed on to a spectrograph where it is resolved into spectral lines, the intensity of at least one spectral line being measured at least 10 times per second by means of one photodetector each, and the measured intensity values for the respective spectral line being used, via a fluctuation analysis, preferably an autocorrelation or a frequency analysis, to calculate diffusion parameters, concentration, size or flow behavior of the particle to which the spectral line in question can be assigned. With this method, it is also possible for signals of different spectral lines or bands, or signals of Raman scattered light, quasi-elastically scattered light and fluorescence light to be correlated with one another.
