Embodiment Construction

[0024] The single-component fast-response pressure-sensitive coating of the present invention includes a pressure-sensitive probe, a polymer adhesive, a filler, and an organic solvent, wherein the above-mentioned ratio is: mass of pressure-sensitive probe: mass of polymer adhesive: mass of filler: organic Solvent volume = 10±0.1 mg: 1.2±0.01 g: 2.8±0.01 g: 40±1 ml.

[0025] Among them, in this embodiment, the preferred proportion is the mass of the pressure sensitive probe: the mass of the polymer adhesive: the mass of the filler: the volume of the organic solvent: 10 mg: 1.2 g: 2.8 g: 40 ml.

[0026] The pressure-sensitive probe is a platinum-based tetrapentafluorophenylporphyrin with a CAS number of 109781-47-7, a porphyrin-based platinum metal complex, and a high-density particle that is light-shielding and airtight at low temperatures Preservation, with strong photosensitive properties and oxygen quenching properties, used for the detection of oxygen content.

Abstract

The invention belongs to pressure measurement techniques and particularly relates to single-component quick-response pressure-sensitive paint and a formulating method. The single-component quick-response pressure-sensitive paint comprises a pressure-sensitive probe, a macromolecular adhesive, filler and an organic solvent in a specific proportion. The macromolecular adhesive and the pressure-sensitive probe are added and dissolved into the organic solvent, and then the filler in a specific quantity is added to obtain the paint. The obtained paint is 0.7% / kPa in pressure sensitivity, applicable to high-speed and low-speed wind tunnel dynamic pressure measurement tests not higher than 1KHz in measurement frequency and also applicable to conventional steady-state pressure measurement tests, a gap of domestic quick-response pressure-sensitive paint can be filled, and simple proportion, convenience, quickness, low cost and high practical application value are realized.

Description

technical field [0001] The invention belongs to pressure measurement technology, in particular to a single-component fast-response pressure-sensitive coating and a proportioning method thereof. Background technique [0002] In the wind tunnel test technology, the pressure measurement of the pressure hole is a conventional pressure measurement technology, but this pressure measurement technology cannot obtain high-resolution continuous model surface friction distribution information, and the traditional dynamic pressure measurement technology can only Relying on dynamic pressure sensors, such sensors are expensive, difficult to install, and inconvenient to operate, which is very unfavorable for aerodynamic researchers to analyze the aerodynamic state of the model. [0003] By analyzing the pressure distribution on the surface of the model, aerodynamic researchers can gain an in-depth understanding of the nature and mechanism of flow phenomena, determine where the airflow atta...
