Aliphatic alcohol sodium sulfate (AS) is commonly known as K12 in China. Its hydrophobic group is lauryl alcohol or coconut oil alcohol. AS has excellent emulsification, foaming, penetration, decontamination and compatibility, and is an important anionic surfactant of alcohol series. The specifications are powder, needle and liquid, and the varieties are different from sodium salt and ammonium salt (ASA). In liquid washing, AS is often used with AES to make the formulation system more mild and foam richer. AS alone has less detergency than AES, but it is easier to form than AES when used in powder detergent products. Ammonium salts are less irritating and milder than sodium salts. They are often used with AESA in shampoos, shower gels and hand sanitizers.

The surfactants used in green detergents should be non-toxic, safe, non-hazardous, biodegradable and renewable green surfactants. Common surfactants that meet this requirement and have been commercialized are alkyl glucoside (APG), sodium fatty acid methyl ester sulfonate (MES), sodium fatty alcohol polyoxyethylene ether carboxylate (AEC), sodium aliphatic alcohol polyoxyethylene ether sulfate (AES), sodium aliphatic alcohol sulfate (AS), aliphatic alcohol polyoxyethylene ether (AE), fatty acid methyl ether. Ester ethoxylates (MEE), coconut oil amide propyl betaine (CAB), etc.

The application principle of surfactant in water-based metal cleaning agent is to weaken or offset the adhesion of oil contamination on metal surface by the properties of wetting, penetrating, emulsifying, dispersing and solubilizing of surfactant, and to accelerate oil contamination from metal surface to be emulsified, dispersed and suspended in lotion by mechanical and physical methods. Solubilizing micelles.

The dilute solution of surfactant obeys the rule of ideal solution. The amount of surfactant adsorbed on the surface of the solution increases with the increase of the concentration of the solution. When the concentration reaches or exceeds a certain value, the amount of adsorbed surfactant no longer increases. These excessive surfactant molecules are disorderly or exist in a regular way in the solution. Practice and theory show that they form associations in solution, which are called micelles.

Despite the use of silicone structural glue in decoration is relatively small, but its quality and performance can not be ignored. After decoration, due to poor quality of sealant or improper use of the loss caused by a small number of families, here to remind you.

Sealant is a kind of sealing material which is deformed with the shape of sealing surface and is not easy to flow. It is an adhesive used to fill the gap between configurations and act as a sealant. It has the functions of leak proof, waterproof, vibration proof, sound insulation and heat insulation.

There are many kinds and types of sealants, and different sealants have different properties and different uses. Polysulfur sealant is one of them. Polysulfur sealant is a kind of sealant made of liquid polysulfide rubber as the main material, with tackifier, vulcanizing agent, accelerator and reinforcing agent. This kind of sealant has excellent properties of fuel-resistant oil, hydraulic oil, water and various chemicals, as well as heat resistance and atmospheric aging resistance. Is polysulfide sealant toxic?

Sealant is a kind of sealing material which is deformed with the shape of sealing surface and is not easy to flow. It is an adhesive used to fill the gap between configurations and act as a sealant. It has the functions of leak proof, waterproof, vibration proof, sound insulation and heat insulation. It can be roughly divided into silicone, polyurethane, polysulfide, acrylic acid, butyl, asphalt and oil resin modified products. Sealants for construction mostly belong to synthetic adhesives. The main body of sealants is polymer. Their properties can be divided into three categories: bulk properties, process properties and use properties.

Through the continuous efforts of researchers, some new flame retardants have been developed to meet the market demand for flame retardants. Intumescent flame retardant is a new type of composite flame retardant system which has attracted much attention in recent years. Because of its unique flame retardant mechanism and halogen-free, low smoke and low toxicity, it meets the requirements of the times for protecting the ecological environment. There is no doubt that this type of flame retardant is an important way to halogenate flame retardants.

Food emulsifier is a kind of food additive which can make the complementary and miscible liquid into uniform dispersed phase (emulsion). A small amount of food emulsifier can significantly reduce the interfacial tension between oil and water and produce emulsifying effect. Surfactants, known as "industrial monosodium glutamate", refer to substances with fixed hydrophilic and lipophilic groups, which can be aligned on the surface of the solution and can significantly reduce the surface tension. It is a large group of organic compounds. Their properties are very unique, and their applications are very flexible and extensive. They have great practical value and theoretical significance. A surfactant used in food emulsifiers.

More and more users are beginning to use polyether amine as raw material, not only because of its performance advantages, but also because it can really fit the application of products, thus achieving a kind of icing on the cake effect. I have to say, its benefits are really too many and too many. Next, let's briefly analyze it. Why should epoxy flooring be used as its raw material? Let's learn from Xiaobian.

Some surfactants with corrosion inhibition properties are commonly used in weak acidic and neutral solutions, especially in oily sewage where the metal corrosion resistance is usually based on lipophilic surfactants. Surfactants with corrosion inhibition can form adsorption film on metal surface. XPS energy spectrum analysis and electrochemical impedance spectroscopy of metal electrode surface in corrosion medium containing surfactants can prove that surfactants act as corrosion inhibitors through geometric coverage effect.

What are the precautions for the use of building sealants? When purchasing, we can not say that the more expensive the better, because the price positioning of the commodity is mainly based on its use, which can be divided into three types: structural rubber, weather-resistant rubber and neutral rubber. The prices of the three commodities are also arranged in order, so it is very important for us to select suitable rubber varieties according to practical needs when selecting products. At the same time, it is very demanding for the environment. It is not suitable for building materials with grease, plasticizer or other solvents. It corrodes copper, brass and other metals. It is also not suitable for all kinds of stone and iron carbide matrix materials. The quality of the project will inevitably be affected. Of course, too slow solidification rate will also lead to problems such as contaminated stone. Therefore, it is suggested that the general drying time of the surface at room temperature should be about 20-50 minutes.

The aviation industry has long been using all kinds of high energy materials that can withstand extreme environments, and foam is one of them. Polyethylene foam, metal foam and polyurethane foam can maintain stable performance in high temperature environment, reduce air leakage, as sound barriers, and make the aircraft operate better in flight and avoid potential hazards.

In solution, surfactant molecules migrate to the surface of solvents, reducing surface tension (water or other solvents). The polar groups of surfactants are directed directly towards the surface of the solvent and hydrocarbon chains are extended into the air. This distribution makes the surface force balance, and consequently the surface tension decreases. The surface tension remained constant after decreasing to the critical micelle concentration, and the surfactant molecules were distributed on the surface of the solvent until the monolayer structure was formed. Surface tension helps to design effective ink. Because the color coating process and these parameters have a great relationship. Many defects in the coloring layer can be attributed to surface tension.

Silicone structural adhesives are the materials formed during construction. The quality of products, using environment, construction technology and other factors will affect the sealing performance of buildings. Baolong Da took the lead in introducing the commitment of "Providing 10-year quality guarantee for the project" and providing after-sales technical support for the products.

The compatibility test and performance test of silicone structural adhesives with contact materials must be carefully carried out before they are put into stock. In the absence of such a report, the Contractor shall be urged to immediately entrust a testing institution with such qualification to carry out special tests for use only after it is qualified.

When polyether amine curing agent is used in construction, we need to further understand its construction technology. Only in this way can we avoid the harm caused by wrong construction methods. So, today, Xiaobian will take you to understand, what is its construction technology?
