Definitions
- the invention relates to a method for combinatorial investigation of the hardening of n hardenable liquid or viscous formulations and a method for the investigation of hardening of individual hardenable liquid or viscous formulations.
- combinatorial materials research many new materials are produced on a small scale and checked for important material properties. By evaluating a large number of measurement results on different recipes, lead structures and structure-effect relationships are identified in so-called combinatorial process loops. These lead structures are then developed through classic optimization in application technology through to the sales product.
- Combinatorial materials research today deals with a large number of different systems. Examples are new catalysts, new structural and functional polymers or improved formulations for a variety of applications. In addition to parallel production and rapid characterization of the recipes, efficient data management is a prerequisite for the success of combinatorial materials research. This includes the automated planning of experiments, their computer-aided execution by controlling synthesis robots and measuring devices, the archiving and visualization of large amounts of data as well as the analysis of these amounts of data to find structure-effect relationships.
- the object of the invention is to provide a method for examining the hardening of concrete mixtures which can be carried out simply and quickly and which can be used in combinatorial materials research.
- the object is achieved by a method for combinatorial investigation of the hardening of curable liquid or viscous formulations,
- the degree of their hardening is determined on each of the n samples at least once by inserting a measuring tip into the sample with a specific force and measuring the maximum penetration depth achieved as a measure of the degree of hardening of this sample, and
- one or more parameters characteristic of the kinetics of curing are determined for each composition of the formulations from the measured values for the penetration depth at different times after the formulations have been prepared.
- n curable liquid or viscous formulations are provided in parallel.
- Suitable containers are, for example, the vessels of a microtiter plate.
- the formulations can be provided automatically or manually.
- an automatic pipetting device can be used, for example, which doses the individual components of the formulations into the containers in the desired amounts.
- the number n of samples provided in parallel is at least 2 and can in principle be of any size. Usually it will be 2 to 1000, preferably 10 to 1000.
- the degree of curing is determined at least once on each of the n formulations.
- a measuring tip with a certain force sticks into the formulation.
- the force that the measuring tip exerts on the sample is usually selected so that the tip penetrates the sample in the uncured state until it reaches the bottom of the container, while it no longer penetrates the sample in the fully cured state.
- the measuring tip can be made of any material.
- the measuring tip preferably has a shape which, when the sample has partially cured, only partially penetrates into the sample.
- the measuring tip is also dimensioned in terms of its diameter such that several individual measurements can be carried out on the same sample without mutual interference.
- the penetration depth of the measuring tip is measured as a measure of the degree of hardening. This is maximum in the liquid or comparatively low-viscosity state of the sample and minimal (ideally zero) in the fully cured state of the sample, and can assume values between these extremes for more or less highly viscous intermediate states of the sample.
- low viscosity and high viscosity are not absolute terms in this context, but are to be understood relative to the force exerted by the tip.
- the penetration depth is measured for a composition of the formulations at different times after the formulation has been prepared.
- the temporally offset measurements of the penetration depth can be carried out on different samples of the same composition. In order to increase the sample throughput, however, it is preferred to carry out several measurements at different times at several spatially separated locations of the same sample.
- the number of puncture points per sample depends on the diameter of the sample container and the diameter of the measuring tip and can be, for example, between 2 and 20. In the case of a standard microtiter plate with 48 containers (diameter of one container approx. 1 cm), it can be 7, for example.
- the highest sample throughput is achieved in that each sample has a different composition from all other samples. To determine the measurement inaccuracy it may make sense to carry out several essentially simultaneous individual measurements on several samples of the same composition.
- One or more parameters characteristic of the kinetics of the curing are determined for each composition from the measured values for the penetration depth at different times after the preparation of the samples.
- a suitable kinetic parameter is the time elapsed before the measured penetration depth has dropped to, for example, half the maximum value since the samples were produced.
- the penetration depth is measured automatically, preferably via a displacement transducer, and computer-controlled.
- the measured penetration depths are recorded and evaluated by a computer.
- the curable formulations can be any systems. Examples are 2-component adhesives or 2-component coating systems, the curing behavior of which is to be examined depending on the composition.
- the measuring tip is preferably cleaned automatically after each individual measurement by washing, brushing and drying.
- the measuring tip can be immersed in a washing liquid and then guided along a brush.
- a force transducer can be used instead of a displacement transducer and instead of the maximum penetration depth of the measuring tip into the sample, the force exerted on the measuring tip when the measuring tip penetrates into the sample can be measured.
- This process variant is otherwise completely analogous to the previously described variant.
- Corresponding kinetic parameters for the hardening of the formulations can be determined from the measured values for this measurement variable, which can be referred to as the penetration force, at different times after the preparation of the samples.
- a suitable kinetic parameter in this variant is the time elapsed until a certain penetration force has been reached since the samples were produced.
- a measure of the effect of a concrete plasticizing polymer is the hardening time of the cement formulation, which is called the time after Production of the cement formulation can be defined, after which the penetration depth has dropped to half of the original value.
- this value can also be determined from a comparatively small number of individual values for the depth of penetration, for example 7 individual values for each sample.
- the process according to the invention is preferably repeated several times, the composition of the formulations being varied systematically.
- the composition of the formulations being varied systematically.
- the cement formulations can be varied systematically from a variety of points of view. Examples are the type and quantity ratio of the monomers contained in the polymers, polymer architecture (use of block copolymers, graft copolymers, statistical copolymers, alternating copolymers, multiblock copolymers), degree of branching, tacticity (isotactic, syndiotactic, atactic), molecular weight, molecular weight distribution, charge state (cationic, anionic, non-ionic), concentration of the polymers in the cement mixture and type of cement used.
- the invention also relates to a device for combinatorial investigation of the hardening of curable liquid or viscous formulations, comprising
- an automatic displacement sensor connected to the measuring tip for measuring the penetration depth of the measuring tip lowered into the sample
- an automatic control, data acquisition, and data evaluation system for controlling the positioner and the robot arm and acquiring and storing the penetration depths measured by the displacement sensor.
- the method according to the invention makes use of a particularly simple and quick method for determining the hardening time of cement formulations. This method of determination can easily be used for only one sample.
- the present invention therefore also relates to a method for examining the hardening of a liquid or viscous hardenable formulation, in particular a cement formulation.
- the degree of hardening of the sample is determined several times, by inserting a measuring tip into the sample several times and at different times with a certain force at spatially separated locations, and measuring the maximum penetration depth achieved as a measure of the degree of hardening of this sample, and
- one or more parameters characteristic of the kinetics of curing are determined for the formulation from the measured values for the penetration depth at different times after the formulation has been prepared.
- the present invention also relates to a device for examining the hardening of a liquid or viscous hardenable formulation, in particular a cement formulation
- an automatic displacement sensor connected to the measuring tip for measuring the penetration depth of the measuring tip lowered into the sample
- an automatic control, data acquisition and data evaluation system for controlling the positioner and the robot arm and for detecting and storing the penetration depths measured by the displacement sensor.
- FIG. 1 a shows the supervision of an individual sample, designated as a whole with 8, with successive puncture points 1 to 7.
- FIG. 1b shows sections through a vessel 12 of a microtiter plate with a single sample 11 with different penetration depths of the tip 10 during different phases of curing 9a (low-viscosity), 9b (high-viscosity) and 9c (hardened).
- FIG. 2 shows a side view of a device for carrying out the method according to the invention with a mechanical positioner 20.
- the positioner moves to the desired vessel of a multi-sample holder 23 and lowers the measuring tip 21 into the vessel with the sample.
- a dial gauge 22 with displacement transducer measures the depth of penetration of the measuring tip. The measured penetration depth is automatically transferred to a computer, saved and evaluated.
