Background technique:Cosmetics and skin care products are commonly used products for modern women. Appropriate makeup can help women have a better appearance and vitality, and enhance their self-confidence. There are many types of cosmetics, which can be classified according to the object of use or the part of use, or according to the production process. At present, the current cosmetics production license in my country is classified according to the latter, which is divided into general liquid ...

Polyurethane foaming agent is the product of cross combination of aerosol technology and polyurethane foam technology. There are two kinds of spongy states in the pipe type and the gun type. Styrofoam is used as a foaming agent for the production of microcellular foams. It can generally be divided into physical and chemical types. This is based on whether the production of gas is a physical process (that is, volatilization or sublimation) or a chemical process (that is, chemical structure). Dama ...

Defoaming mechanism1. The decrease of the local surface tension of the foam leads to the collapse of the foamThe origin of this mechanism is to sprinkle higher alcohol or vegetable oil on the foam. When it dissolves into the foam liquid, it will significantly reduce the surface tension there. Because these substances are generally less soluble in water, the reduction of surface tension is limited to the part of the foam, and the surface tension around the foam hardly changes. The part with reduc ...

The role of active ingredients: foam breaking, defoaming, reducing surface tension: Representatives: silicone oil, polyethers, higher alcohols, mineral oils, vegetable oils, etc. [1] (2) Emulsifier function: Disperse the active ingredients into small particles, which are easy to disperse in water, and have better defoaming and anti-foaming effects. Representative: non(octyl)phenol polyoxyethylene ether, soap salt, op series, Tween series, Span series, etc. (3) Carrier function: Conducive to the ...

When it interacts with the substrate, it releases ethanol and combines with the substrate to convert it into a silicone resin polymer, and finally forms a hydrophobic silicone resin film on the surface of the pores of the substrate to prevent water and harmful ions from penetrating The inside of the base material achieves the purpose of waterproof protection, improves the strength of building materials, prolongs the service life of the building, reduces the maintenance cost of the building, and ...

The function of the raising agent is to make the fabric soft and fluffy, and it is easy to raise the fabric when it is processed by the raising machine. Some modified silicone oils and water-dispersible polyester derivatives can all be used as raising agents.The fabric passes through a series of raising rollers covered with steel wire card clothing. The needle points of the metal card clothing pick up the fibers in the weft yarn of the fabric and generate fluff after being hooked. These raising ...

Any paint that uses water as a solvent or as a dispersion medium can be called a water-based paint. According to the type of binder in the paint, water-based paints are divided into two categories: natural water-based paints made of natural substances or minerals (such as potassium silicate) and petrochemical water-based paints made of synthetic resins (such as acrylic resins). Only the water-based paint of artificial synthetic resin is described here.Water-based paint includes three types: wate ...

In many inks and coatings processing production process, the need to use surface-active substances to achieve special effects. For example, in the production of water-based paint, water-insoluble base material production, water-insoluble base material is required to deal with the use of emulsifiers. At the same time, we have to improve substrate wetting and coating pigment dispersion by using additives.Surfactant most important characteristic is that they have a tendency to build in the interfac ...

One. Product name Potassium methyl silicateTwo. Product introduction:This product needs to be diluted with water when used. It is used for the treatment of materials such as stone and bricks, ceramics, cement mortar, perlite, gypsum and fiber gypsum board, especially porous materials, which can produce surface waterproof and reduce water absorption. It is permeable and absorbable, and can maintain the natural appearance of the substrate without changing the original color and appearance of the s ...

One: What can be used as a cleaning agent for silicone oil?Of course it is a silicone oil cleaning agent, as I have already said. Mainly used in clean clothes, nitrile gloves, rubber gloves, FPC circuit boards, precision electronic components, etc., with good cleaning and anti-rust effects.Two: the principle of silicone oil cleaning agentSilicone oil cleaning agent is a water-polyol-based mixture accurately synthesized by high-quality anionic and non-ionic surfactants to produce a near neutral c ...
