What is a Coupling Agent -- 2020-10-13

Coupling agent is a kind of substance with two functional groups with different properties. The biggest feature of its molecular structure is that the molecule contains two groups with different chemical properties. One is an inorganic-philic group that easily reacts with the surface of inorganic substances. The other is an organophilic group, which can chemically react with synthetic resins or other polymers or generate hydrogen bonds to dissolve them. Therefore, coupling agents are called &quo ...

Selection and Evaluation Method of Defoamer: -- 2020-10-12

The defoamer must be able to spread quickly on the surface of the foam and be able to penetrate quickly to make the foam burst quickly. The commonly used types of defoamers are silicones and polyacrylates.Silicone defoamers are usually of the polysiloxane type. For example: polydimethylsiloxane containing acrylate functional group and polyether modified polydimethylsiloxane, etc. Silicone has high temperature resistance, low temperature resistance, stable physical properties, chemical inertness, ...

Some Common Sense about Silicone Oil-containing Shampoo -- 2020-10-10

There was a saying on the Internet that 90% of shampoos contain an ingredient called "polydimethylsiloxane", which is the so-called silicone oil smoothing agent. Rumors say that because this chemical substance of silicon or dimethylsiloxane fills the gaps between the hair scales, the hair is very smooth after washing, but due to the impermeability and inertness of silicon, it will Clog the pores, it is easy to make the scalp itchy, even hair loss, hair loss, etc. Let us know some commo ...

The Difference between Silicone and Silica Gel -- 2020-10-09

Resin usually refers to an organic polymer that has a softening or melting range after being heated, and has a tendency to flow under the action of external force when softened. It is a solid, semi-solid, or liquid organic polymer at room temperature. Broadly speaking, any polymer that can be used as a raw material for plastic products processing is called a resin.Plastic refers to a material that uses resin (or directly polymerized with monomers during processing) as the main component, and add ...

Preliminary Study on Application of Silicone Oil Stabilizer -- 2020-09-29

At present, the silicone oil emulsion used in the textile printing and dyeing industry is very extensive, and the amount of use is also very large. Roughly speaking, the most mainstream silicone oil emulsions are divided into two categories:1. Ordinary amino silicone oil emulsion       This category is currently mainly reflected in ice-feeling silicone oil, smooth silicone oil, smooth silicone oil, soft silicone oil, etc. It is mainly used on cotton and cotton blended stretch ...

Traditional Softener and Silicone Softener -- 2020-09-28

Softeners can be divided into two types: fatty acid derivatives and silicone oils. The former is a traditionally widely used softener, and the latter is a new species that comes from behind. The development of silicone softeners is fast, and new varieties with various properties and functions are constantly being developed and marketed.Because silicone softeners not only have better softening effect than traditional softeners, but also the finishing effect has better durability. Therefore, it ha ...

Introduction and Development of Silicone Anti-sticking Agent -- 2020-09-27

Silicone anti-sticking agent refers to a kind of anti-sticking material with low toxicity, low polarity, low surface tension and immiscibility with organic polymers. It is a kind of anti-sticking agent widely used at present. Silicone anti-sticking agent is currently the most widely used anti-sticking agent, and it is also a kind of organic silicon material with huge market and broad prospects.There are three types of silicone release agents: solvent type, water emulsion type, and solvent-free t ...

Application of Silicone Oil Defoamer in Petroleum Industry -- 2020-09-25

Silicone oil defoamers are widely used in the petroleum industry and have become an indispensable and important additive in the production process. Due to the extensive use of strong foaming surfactants in drilling fluids, defoamers are not only indispensable for extracting crude oil, but defoamers must also be used in the post process of crude oil refining. In the crude oil distillation process, silicone oil defoamer is used. Secondly, the gas removed from the top of the tower or the natural ga ...

The Difference between Oily and Water-based Waterproof Materials -- 2020-09-24

One: Environmental protection From the perspective of environmental protection, water-based coatings have natural advantages over oil-based coatings (solvent-based wood coatings). In theory, the lower the VOC content, the higher the environmental protection, but the low VOC content has an impact on the abrasion resistance, hardness, and scratch resistance of oil-based coatings. The above indicators have always been technical problems that need to be overcome in water-based coatings. How to achie ...
