Silicone oil because of no polarity, generally dissolved in non-polar solvents, insoluble in polar solvents. And depending on the size of the viscosity, the lower the viscosity easier to dissolve. Benzyl silicone oil is better than methyl silicone oil. Silicone oil on a variety of vitamins, fungicides, anti-inflammatory agents have dissolved ability, so all kinds of nutrition cream, drug cream with silicone oil, due to the formation of a layer of hydrophobic membrane on the skin surface, thereby ...

The entire molecule of the silicone oil has a helical structure, the polarity of the siloxane bonds is offset from each other, and the force between the molecules is very small, so that the surface tension is low. In the skin surface can quickly spread to form a uniform film. That is, the amount is very small, but also to the skin a high degree of hydrophobicity, while not affecting the normal perspiration. Silicone oil can impart appropriate moisture to the skin's stratum corneum and is a good ...

With the development of daily chemical industry and the increasing level of people's consumption, personal care products put forward a wider range of requirements. Due to the industrial development, the degree of air pollution is increased, the use of chemical products such as detergents, brighteners, pesticides, fertilizers and other chemical products makes people's skin more and more chemicals. Therefore, the requirements of personal care products can not only modify the face, hair and hands, ...

High resilience foam, also known as cold foam. Is a low hysteresis, low modulus polyamide foam, which is produced without heating and aging, with high resilience (ball springback) and higher comfort (compression factor) 2.7). Generally, high active polyethers and r or polymer polyols (or polychromatic dispersions polyols) with isoprid content of 7 50'6 (moles) are prepared with isocyanates. It can be produced in block and molded foam molding processes. Mainly used in transportation and furniture ...

Gypsum board is a natural gypsum and face paper as the main raw material, mixed with appropriate amount of fiber, starch, coagulant, foaming agent and water made of lightweight construction sheet. In performance there are the following characteristics:Low energy efficientProduction of the same unit of paper gypsum board energy consumption than cement savings of 78%. And the investment less production capacity, simple process, easy to large-scale production.LightweightWith gypsum board for the wa ...

1) kitchen waterproof gypsum board ceiling with a beautiful appearance, if the overall home is European-style personality, the kitchen ceiling decoration using gypsum ceiling is appropriate, and looks more beautiful appearance, and more than other varieties of the ceiling is more advanced, is a Very suitable for European style kitchen decorated with a ceiling.2) gypsum board is mainly used for engineering or home decoration with their own because of good resistance, and offer relatively cheap, h ...

As the gypsum board porosity is large, and the pore structure distribution is appropriate, it has a high permeability. When the indoor humidity is high, can be moisture, and when the air is dry, but also release part of the water, and thus play a certain role in the regulation of indoor humidity, foreign gypsum board this function called "breathing" It is precisely because the gypsum board has this unique "breathing" performance, can be adjusted within a certain range of indo ...

The principle of water repellent of silicone milk: When the polysilicone milk heated to 140 ℃ or more, the polysiloxane in the fabric orientation, hydrophobic base - CH3 outward, polysilicone oil emulsion silicon atoms, oxygen atoms and fiber Some atoms form valence bonds and hydrogen bonds, so water vapor, air through the fabric, water droplets can not pass. Polyether oil emulsion chain at the top of the hydroxyl and hydrogen-containing silicone oil grafting, that is, hydrogen-containing silic ...

Waterproof gypsum board refers to the slab in the United States under the ASTM standard for waterproofing test, the water absorption rate of 5%, that can be used for large areas of humidity, such as the bathroom, shower and kitchen, the board is in the gypsum core Material to add a quantitative waterproofing agent, so that the plaster itself has a certain waterproof performance. In addition, gypsum board paper is also waterproof, so this is a better use of a wider range of plates. But this board ...
