The 2025 Annual Work Summary Conference of Shandong Xunda Chemical concluded successfully.
On January 13, 2026, the 2025 Annual Summary Conference of Shandong Xunda Chemical Group Co., Ltd. was solemnly held in the multi-functional conference hall at the group’s headquarters. All members of the management team, key personnel from various departments, and employee representatives gathered together to conduct an in-depth review of key areas of work, including the achievement of annual production and operational targets, breakthroughs in core technological innovation, implementation of safety and environmental protection responsibilities, and results in market expansion. The conference systematically summarized the remarkable achievements made over the past year in such areas as the development of green chemical products and the upgrading of intelligent production lines. At the same time, it candidly analyzed shortcomings in areas such as supply chain collaboration efficiency and the reserve of high-end talent, thereby clearly defining the direction for optimizing future work.

Application of Molecular Sieves in Insulated Glass
Selecting the appropriate type of molecular sieve plays an indispensable role in determining the quality and service life of insulated glass. The invention of sealed insulated glass dates back to 1865; initially, insulated glass was simply constructed without any adsorbents or organic sealants. However, it was only with the global energy shortage and the development of modern organic sealants and adsorbents that demand for insulated glass experienced tremendous growth. Thanks to its outstanding thermal insulation, soundproofing performance, as well as its bright and aesthetically pleasing characteristics, insulated glass has become increasingly widely used. China began developing insulated glass in 1964, and from its early manual production methods, it has now made significant progress in both quality and output.

How to identify the target protein in gel filtration and molecular sieve chromatography?
Gel filtration separates different substances based on their molecular size and is often used for desalting protein solutions. For protein solutions whose component molecules have known molecular weights, the elution time of the target protein can be estimated by comparing their molecular sizes. However, if the properties of various proteins are unknown, the only option is to collect each protein peak separately and then identify them. So, how can we estimate the elution time of the target protein simply by comparing molecular sizes? Proteins with larger molecular weights cannot enter the pores of the gel and thus have shorter elution times; conversely, proteins with smaller molecular weights can enter the gel pores and have longer elution times. Yet, this relationship is relative—for example, two large protein molecules might both fail to enter the pores at all.
