Exploration of C9 petroleum resin detection method

As an important chemical raw material, C9 petroleum resin is widely used in various industries, so it is very important to detect its quality accurately and reliably. At present, the detection method for C9 petroleum resin has been developed by leaps and bounds, covering a variety of technical means, below we will focus on several of the main methods.

1. infrared spectroscopy

Infrared spectroscopy is a commonly used analytical technique and one of the important means to detect C9 petroleum resin. This method uses the characteristics of molecular vibration absorption to determine the composition and structure of the sample by detecting the interaction between the sample and infrared light. The quality and composition of C9 petroleum resin samples can be accurately judged by infrared spectroscopy, which provides an important reference for production and quality control.

2. gas chromatography

Gas chromatography is an efficient method for the separation and analysis of sample components, and also has high applicability for the detection of C9 petroleum resin. The method uses the distribution behavior of the sample in the gas carrier to separate and quantitatively analyze the various components in the sample through a chromatographic column. Gas chromatography has the advantages of high separation efficiency, high sensitivity and fast analysis speed, and has been widely used in the quality detection and composition analysis of C9 petroleum resin in the chemical industry.

3. nuclear magnetic resonance method

Nuclear magnetic resonance method is a very accurate analysis technology, which has unique advantages for the structural analysis and composition detection of complex samples, and has been widely used in the detection of C9 petroleum resin. The method uses the phenomenon of nuclear magnetic resonance to determine the structure and composition of the sample by detecting and analyzing the resonance signals of atomic nuclei in the sample. NMR method has the characteristics of high resolution, rich information and non-destructive, which is one of the important means to study the properties and quality of C9 petroleum resin.

The detection methods for C9 petroleum resin include infrared spectroscopy, gas chromatography, nuclear magnetic resonance and other technical means. Each method has its unique advantages and scope of application, and can select the appropriate method for detection and analysis according to the actual needs to ensure the improvement of product quality and production efficiency.

In-depth analysis of C9 petroleum resin application technology

As an important chemical raw material, C9 petroleum resin is widely used in paint, ink, adhesive, coating and other industries. Therefore, the analysis and control of its quality and performance is very important for the production and product quality of related industries. Below we will analyze the application technology and development trend of C9 petroleum resin in different industries.

1. in the paint industry application

In the paint industry, C9 petroleum resin is often used as a plasticizer and curing agent for solvent-based paint coatings, which can improve the adhesion, hardness and weather resistance of the paint film. C9 petroleum resin can also be used to adjust the rheological properties of the paint film, improve the processing performance and construction performance of the coating, and make it more suitable for various process requirements. In the future, with the improvement of environmental awareness, the application of C9 petroleum resin in water-based paint will be more extensive.

2. in ink industry application

In the ink industry, C9 petroleum resin is often used as a plasticizer and colorant for ink, which can improve ink adhesion, color stability and printing performance. C9 petroleum resin can also adjust the rheological properties and drying properties of the ink, improve the quality and efficiency of the printed matter, and meet the market requirements for the quality and appearance of the printed matter. In the future, with the development of digital printing technology, the application of C9 petroleum resin in UV ink and water-based ink will be more extensive.
