Why is fast-curing acrylic resin the core consumable of cold mounting process?- Trojan (Suzhou) material technology Co., Ltd.

Fast-curing acrylic resin has many remarkable characteristics that make it stand out in cold mounting process.

In terms of curing speed, its curing time is usually completed within 5-15 minutes, which greatly shortens the sample preparation cycle compared with other types of cold mounting resins, such as epoxy resin (curing time 1.5-24 hours). This advantage is particularly important in some time-sensitive experiments or production scenarios. For example, in the electronics manufacturing industry, quickly obtaining samples for quality inspection and analysis can timely discover problems and adjust production processes, improve production efficiency and product quality.

In terms of shrinkage, fast-curing acrylic resin performs well. During the curing process, its shrinkage is extremely low, which helps to maintain the original shape and dimensional accuracy of the sample. In the field of materials science research, for some microstructure analysis, the size change of the sample may affect the accuracy of the analysis results, and low-shrinkage acrylic resin can effectively avoid this problem and provide researchers with more reliable experimental data.

Transparency is also a highlight of this resin. Although ideal transparency may not be achieved under normal pressure, highly transparent samples can be prepared with the help of additional pressure (generally achieved through a special pressure cooker). This is crucial for analytical work that requires observation of the internal structure of the sample, such as the observation of the internal structure of electronic components in failure analysis. Highly transparent samples can provide a clearer field of view and facilitate accurate judgment of the cause of failure.

Operational convenience is also an important feature that cannot be ignored. Rapid-curing acrylic resins are usually binary sets, that is, they are composed of a powder and a liquid. When used, they can be mixed in a certain proportion without complicated mixing processes. Moreover, it has low requirements for pressure and external heating. Except for special circumstances, additional pressure and heating conditions are usually not required, which greatly reduces the difficulty of operation and improves the convenience of sample preparation.

In materials science research, rapid-curing acrylic resins provide strong support for studying the microstructure of materials. By preparing high-quality cold-mounted samples, researchers can use various analytical methods, such as scanning electron microscopy (SEM), transmission electron microscopy (TEM), etc., to conduct in-depth research on the microscopic morphology, crystal structure, phase composition, etc. of the material. For example, when studying the performance of new alloy materials, it is necessary to observe their grain size, phase distribution, etc. The samples prepared by fast-curing acrylic resin can meet these analytical requirements, help researchers better understand the relationship between the performance and microstructure of the material, and provide a theoretical basis for the research and development of new materials.

The electronic manufacturing industry has extremely high requirements for product quality and reliability, and fast-curing acrylic resin plays an important role in this field. In the manufacturing process of electronic components, such as the production of printed circuit boards (PCBs), components need to be quality tested and analyzed. Through the fast-curing acrylic resin cold embedding technology, samples suitable for analysis can be prepared to observe the internal structure of the components, welding quality, etc. Timely detection of potential defects and problems, such as cold solder joints and short circuits, helps companies to adjust production processes in a timely manner, improve product quality, and reduce the rate of defective products.

When electronic components or other products fail, failure analysis is a key link in finding the root cause of the problem. The fast-curing acrylic resin cold embedding technology can prepare high-quality failure samples, which is convenient for analysts to observe and analyze the structural and composition changes of the failure site. For example, when analyzing the failure causes of electronic components, by observing whether there are cracks, corrosion, etc. inside the sample, combined with energy spectrum analysis and other means, it can be accurately determined whether the failure is caused by material defects, manufacturing process problems or environmental factors, providing important reference for product improvement and optimization.

With the continuous development of technology, single-component UV curing resins have emerged. Taking QPREP UV 50 resin as an example, it does not require the effort to mix the resin and curing agent ratio. It only needs to inject the resin into the sample mold and then irradiate it with ultraviolet light of a specific wavelength to complete the curing within 60 seconds. This technological breakthrough greatly improves the efficiency of sample preparation, reduces human mixing errors, and makes the sample preparation process more standardized and normalized. The stability of single-component resins is also better, which can ensure the consistency of sample quality.

The emergence of the accompanying QATM Qmount UV light curing machine has further promoted the application of fast-curing acrylic resins. The device has the characteristics of a large scratch-resistant glass plate size (200x260mm) and can simultaneously cure up to 12 samples with a diameter of 40mm, achieving high-capacity synchronous mounting. This not only improves the sample preparation efficiency, but also reduces the sample preparation cost of a single sample. In addition, the device is extremely easy to operate, the process parameters are clearly displayed on the color display, and can be continuously adjusted by the knob. The laboratory health and safety are also well considered. It is equipped with an interface for external suction as standard. After the suction device with activated carbon filter is selected, steam and odor can be filtered, providing a good working environment for operators.
