Steady increase in production and sales, transformation support is still insufficient. Recently, the Spanish Federation of Chemical Companies (Feique) released statistics. Compared with 2023, 2024 Spanish chemical sales are expected to grow by 4.8%. Reaching 86.5 billion euros. And production is expected to grow by 7.1%. Feique forecasts that Spain’s chemical sales will grow by […]
LG Chem has announced the signing of a cooperation agreement with Alkhorayef Group for the localization of reverse osmosis membrane manufacturing facilities. The two parties plan to start localized operations of reverse osmosis membrane manufacturing facilities in 2026. In the future, the partnership will result in an investment of up to SAR 320 million for […]
Recently, China’s State Administration for Market Supervision and Administration and China’s National Standardization Administration released the national standard for carbon emission accounting for phosphoric acid and phosphate enterprises, “Greenhouse Gas Emission Accounting and Reporting Requirements Part 45: Phosphoric Acid and Phosphate Enterprises”. It is reported that the standard is led by Guangdong Bangpu Cycle Technology […]
In the production process of triazine UV absorbers, the production of intermediates is the key part, which determines the production capacity of the corresponding products. The specific process is as follows. 1. The synthesis process of UV-1164, UV-400 and UV-405. The synthesis process of UV-1164, UV-400 and UV-405 is shown in Figure 1. The synthesis […]
At present, the UV absorbers used in polymer materials mainly include benzotriazoles, benzophenones, salicylates and triazines. Among them, the amount of benzotriazole UV absorbers is the largest and the application range is the widest. Compared with benzotriazole UV absorbers, triazine UV absorbers are the latest class of products. These products have the advantages of high […]
By means of nuclear magnetic resonance carbon spectroscopy and phosphorus spectroscopy structure identification. And combined with physical and chemical index analysis. A quality assessment method applicable to the water treatment agent PBTCA was proposed. PBTCA has excellent resistance to calcium carbonate scale and zinc stabilization performance. It has the advantages of stable structure, low phosphorus […]
The corrosion inhibition performance, corrosion inhibition efficiency, thermal stability, and chlorine resistance of tolyltriazole and benzotriazole were compared under different pH conditions. The experimental results showed that tolyltriazole has better corrosion inhibition, thermal stability, and chlorine resistance than benzotriazole. It can replace benzotriazole in the automotive industry and water treatment industry. Benzenetriazole, molecular formula C6H5N3, […]
In the 1970s, American geologists drilling in the ocean discovered what looked like ordinary dry ice. When it was salvaged from the ocean floor, the “ice” quickly became bubbling mud and water. And those bubbles were accidentally ignited, and these bubbles are methane. According to the research, these grayish-white substances, like dry ice, are solid […]
Hot Glue is a kind of adhesive with plasticity. Its physical state can change with temperature within a certain temperature range, while its chemical properties remain unchanged. Hot glue is non-toxic and odorless. It is an environment-friend chemical product. Because Hot Glue is solid, it is easy to pack, transport and store. Hot Glue is […]
