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 […]
WACKER recently announced that it has developed a new silane for use in the production of highly integrated memory chips and microprocessors, expanding its portfolio of specialized products for the semiconductor industry. It can be used for chemical vapor deposition in semiconductor production. The new silane reacts with the wafer surface. An extremely thin insulating […]
Recently, Dow Chemical announced that the company has decided to close the polyether polyol production plant at its San Lorenzo plant in Santa Fe province, Argentina, mainly due to the global polyol oversupply that has caused the San Lorenzo plant to continue to operate at a low start-up rate, which is difficult to maintain. Polyether […]
Bromine is a halogen element with chlorine, and its chemical properties and microbicidal effects are basically similar to those of chlorine. However, the solubility of bromine in water is much smaller than that of chlorine. Bromine-containing disinfectants have the advantages of high efficiency, broad-spectrum sterilization and strong bactericidal effect. These advantages have led to the […]
Abstract: Benzoisothiazolinone is an excellent preservative for coatings and plastics. In this paper, the properties, bactericidal mechanism and application fields of benzothiazolinones are described in detail. The advantages of 1,2-benzoisothiazolin-3-one over traditional Kathon fungicides were compared. The synthesis methods of benzoisothiazolinones and the advantages and disadvantages of different synthesis methods are introduced in detail. Keywords: […]
BKC 80% for Aquaculture The success of aquaculture depends largely on the aquatic environment. When the pond water is polluted and the environment is infected by bacteria, much organic matter affects fish and shrimp. At this time, the pathogen can easily penetrate and cause diseases in fish and shrimp. Therefore, improving the environment and disinfecting […]
Benzalkonium bromide, also known as New Germinal, is a quaternary ammonium salt cationic surfactant with a bactericidal effect. At room temperature, benzalkonium bromide is a yellow colloid. At low temperatures, it may gradually form a waxy solid. The aqueous solution of benzalkonium bromide is an alkaline reaction and produces a lot of foam when shaking. […]
Tetrakis hydroxymethyl phosphonium sulfate is a new type of quaternary phosphate salt fungicide. It has the advantages of low toxicity and environment friendly. A series of static sterilization experiments and dynamic experiments show that THPS biocide is used in water treatment systems, with broad-spectrum, high efficiency, and fast-killing characteristics. And good compatibility with common corrosion […]
Abstract Purpose： To observe the disinfection effect of polyhexamethylene biguanide disinfectant on the surface of hospital objects. Methods： Cotton swab sampling and bacterial quantitative culture were used. The effect of a polyhexamethylene biguanide disinfectant on the surface of objects in hospital wards was observed. And do parallel comparison with chlorine-containing disinfectant. Results: The disinfectant concentration […]
What is biocide polyhexamethylene biguanide? Polyhexamethylenebiguanide is a new international safe and non-toxic polymeric guanidine bactericide. The methylguanidine in its derivative polyhexamethyleneguanidine hydrochloride has high activity itself. This activity can make the polymer is positively charged and easily adsorbed by bacteria and viruses. Thus, it inhibits the division function of bacteria and viruses and disables […]
