In daily life, it’s common to see households using humidifiers to add moisture to the air. But why is humidifying the air necessary? How should humidifiers be used correctly? What is the proper way to use a humidifier? The Importance of Air Humidity According to national indoor air quality standards, good indoor air quality requires […]
Throughout the entire production, storage and usage process in the cosmetics industry, preservatives serve as core ingredients that ensure product quality, usage safety and shelf stability. They effectively inhibit microbial growth, preventing product deterioration and failure. As one of the industry’s commonly used preservatives, Bronopol (chemical name: 2-Bromo-2-Nitropropane-1,3-Diol) is widely adopted for its outstanding preservative […]
Industrial microbial contamination is the primary cause of system corrosion, efficiency decline, product spoilage, and shutdowns for cleaning. Traditional oxidative biocides suffer from significant pH sensitivity, prone to byproduct formation, equipment corrosion, and poor compatibility issues; while conventional non-oxidative biocides exhibit drawbacks such as slow onset, high residues, and poor biofilm penetration. DBNPA-based biocides have […]
Glutaraldehyde is an indispensable key chemical in the fields of medical disinfection, dental therapy, vaccine manufacturing, and biological research. As a typical saturated dialdehyde compound, it exhibits unique chemical reactivity and biocompatibility, making it a core raw material and auxiliary reagent in modern biomedicine, pharmaceutical industry, and industrial production. This guide systematically elaborates on the […]

Introduction to Peat and its Significance Peat, often considered a humble natural material, has recently taken center stage in environmental remediation efforts. Researchers at Xihua Normal University, led by the innovative Professor Li Wenbin, have unveiled peat’s untapped potential in combating agricultural pollution—a revelation that could reshape our approach to environmental management. Why Peat? An […]
As an engineer in a chemical plant’s water treatment workshop, I know drinking water safety is central to public health. Bactericides are key fine chemicals that ensure drinking water is biologically safe. In real-world operations, drinking water treatment must address natural bacteria in water sources, pipeline biofilms, and secondary contamination. The selection, dosage control, and […]
As a common bactericide carrier in drinking water purification, water purification tablets primarily function by leveraging their bactericidal active ingredients to rapidly eliminate pathogenic microorganisms (such as bacteria, viruses, and protozoa) in water. Additionally, certain types can assist in removing small amounts of impurities, ultimately bringing non-potable water up to temporary drinking standards. Their working […]
The annual conference of the European Petrochemical Association (EPA) was held in Berlin. The global trade flow of chemicals is currently undergoing constant change, says the CEO of the Swiss chemical logistics group Northall Flag. Demand for new chemical logistics routes and infrastructure will emerge. Bertschi noted, “The reality is that emerging countries in different […]
