In 1975, DuPont took the lead in developing the second-generation acrylic adhesive (SGA) [1], and subsequently ITW, Loctite, lord and other companies have also developed SGA products with their own characteristics. Domestic development of SGA started slightly late, but after a period of technology a
1. Composition and structure of esterAn ester can be regarded as the product of the carboxylic acid molecule after the -OH is replaced by -OR '.Abbreviated as RCOOR ', R and R´ can be the same or different. Functional groups are ester based pictures. The general formula of the ester formed
In this paper, the antibacterial mechanism of Gemini surfactants was introduced. The word Surfactant comes from the English Surfactant, which is a condensation of the phrases Surface, Active and Agent [1]. Surfactants are substances that are active on surfaces and interfaces, have a very high abilit
Abstract: The principle, application and research status of surfactant in chemical cleaning were reviewed, and the existing problems were analyzed. It is pointed out that the synthesis of biodegradable green surfactants and the development of green synthesis technology of surfactants are important d
The emulsion is a heterogeneous dispersion system with thermodynamic instability and the droplet tends to coalesce automatically. The early theory of emulsion stability has noted that the addition of surfactants, polymers, and even solid particles plays an important role in the formation and type of
Background and OverviewBenzyl methacrylate is an active diluent of acrylic acid, which has the advantages of high flash point and stable storage at room temperature and pressure. Its polymerized products have high refractive index, high hardness, low shrinkage and excellent heat resistance, and can
This paper investigates and analyzes the development status and future trend of cyclohexyl methacrylate (CHMA) in the world. The core contents are as follows:(1) The overall size of the global market has been statistically analyzed by sales volume and revenue respectively, with historical data from
01Surface tensionThe contraction force of any unit length of the liquid surface is called the surface tension, and the unit is N•m-1.02Surface activity and surfactantsProperties that reduce the surface tension of a solvent are called surface active, and substances that have surface activity are cal
Source: Medical Education NetworkThe use of surfactants in combination with each other or with other compounds is called compounding. In the application of surfactant solubilization, if the appropriate compatibility can be selected, the solubilization ability can be greatly increased and the amount
The recent palm oil futures price continued to adjust, and the main 2301 contract fell below the 10-week average support, and the futures price ran below the 7,800 yuan/ton mark. From the basis point of view, among the three major oil varieties, rapeseed oil maintained a high basis difference, soybe
