Problems solved by technology

Most oil and gas fields in the world, especially those in undeveloped regions, still partly rely on manual portable gas detectors for patrol inspection, which can neither realize full coverage detection of equipment, pipelines and typical connection parts in time and space, nor affect the personal safety of operators. Safety poses a great hidden danger

Abstract

The invention provides a characteristic response material and a preparation method thereof, in particular to a characteristic response material for monitoring and detecting hydrogen sulfide gas leakage and a preparation method thereof; the hydrogen sulfide gas response material consists of a matrix material, a modified color Glycosides and TiO 2 Prepared from raw materials such as porous microspheres, matrix materials, modified anthocyanins and TiO 2 The mass percentages of the porous microspheres are: 60-70%: 5-15%: 2-10%; the responsive material can be used in the fields of petrochemical, natural gas and coal chemical industries, and can solve the problem of detecting a large amount of hydrogen sulfide gas in the prior art. Relying on the shortcomings of precision instrument airtight detection or manual carrying operation detection, it has technical effects such as wide monitoring coverage, high sensitivity, visual visibility and convenient construction; it can also be used with anti-corrosion protection materials to achieve wrapping protection and vulcanization of connection parts Integration of hydrogen gas corrosion leakage monitoring.

Description

technical field [0001] The invention relates to a characteristic response material and a preparation method thereof, in particular to a characteristic response material for monitoring and detecting hydrogen sulfide gas leakage and a preparation method thereof. Background technique [0002] Responsive materials refer to a class of special materials whose surface or internal molecular structure or state will change greatly when the external environment (such as pH value, light, temperature, voltage and gas, etc.) changes. This property of sensitive response to environmental changes can lead to large changes in the physical or chemical properties of materials, which can be detected by human senses or simple instruments. [0003] Hydrogen sulfide is an irritating and suffocating acidic and highly toxic gas. When the concentration of hydrogen sulfide molecules in the air reaches 15ppm, the contact person will lose consciousness, apnea and olfactory system inactivation. When the h...
