The use of this silicone elastomer in skin care and sunscreen products can help the product form a firm and smooth e ...

On August 5th, Beijing time, the Tokyo Olympic Games has ended its 12th competition day. The Chinese Olympic Team did not have a gold medal in the account yesterday, relying on synchronized swimming to win a precious silver medal in the double final. The Chinese combination Huang Xuechen/Sun Wenyan won the silver with 192.4499 points regrettably. The champion belongs to the Russian synchronized swimming team. They have a strong dominance in this event and have won five Olympic gold medals. China ...

The board core and protective paper have been waterproofed. According to the requirements of the national standard, the paper surface and board core of the water-resistant gypsum board must meet certain waterproof requirements (the surface water absorption is not more than 160 grams, and the water absorption rate is not more than 10 %). Water-resistant gypsum board is suitable for use in places where the continuous relative humidity does not exceed 95%, such as toilets, kitchens, bathrooms, etc. ...

1. According to the strength of the role, it can be divided into two categories:(1) Solvents with low surface tension and water miscibility, including ethanol, propylene glycol, glycerin, dimethyl sulfoxide, etc.(2) Surfactants, such as anionic surfactants, certain polyol type surfactants (Spanish type), polyoxyethylene type surfactants (Tween type)2. According to the route of administration, it can be divided into three categories:(1) Wetting agents used in external preparations include surfact ...

The scientific name of organosilicon is polysiloxane resin. In the polysiloxane molecule, the ratio of the organic substituent (R) to the silicon atom (Si) is an important parameter that determines the product form. When R/Si<2, the product is silicone resin; when R/Si≈2, it is a high viscous plastic state, namely silicone rubber; when R/Si>2, it is a low molecular weight oil, Called silicone oil.Performance parameter The explanations are as follows:Appearance: The external appearance of ...

Bubble powder brings various problems to industrial manufacturing: in order to prevent the bubble powder from overflowing, the feed index is reduced by 35%~55%; the bubble powder overflows and causes the waste of raw materials; the bubble powder takes up space and affects the reaction. Speed, the production period can’t help but extend the time; foam will affect the quality of products, such as textile coatings, plastic products; the formation of foam will affect the stability and reliability o ...

A substance that can make solid materials more easily wetted by water. By reducing its surface tension or interfacial tension, the water can spread on the surface of the solid material or penetrate the surface, thereby wetting the solid material.Wetting agent is a surface active agent that can make solid materials more easily wetted by water by reducing its surface energy.Such as sulfonated oils, soaps, pull open powder BX, etc., soy lecithin, mercaptans, hydrazides and mercaptan acetals, etc. c ...

Silicones The most commonly used is polydimethylsiloxane, also known as dimethyl silicone oil. It has low surface energy, low surface tension, low solubility in water and general oil, and high activity. Its main chain is a silicon-oxygen bond, which is a non-polar molecule. It has no affinity with polar solvent water, and has little affinity with general oils. It has low volatility and chemical inertness, relatively stable and low toxicity. Pure dimethiconeAlkane, it is difficult to be used as a ...

Paint wetting agents are divided into two types: substrate wetting agent and wetting dispersing agent. The substrate wetting agent is used to improve the surface tension and permeability of the coating, so that it can better wet the substrate, thereby improving Coating adhesion, especially for improving the adhesion of primers to substrates, is widely used, generally some fluorocarbon or fluorocarbon modified ionic or non-ionic substances or other substances that can improve the wetting of the s ...

Background technique:Agricultural aviation plant protection is the use of planes to spray pesticides or fertilizers to prevent and control diseases, pests, and weeds in farmland, forests, and grasslands or to manage field growth. During the aerial plant protection spraying process, since the spray volume per mu is 0.5-1.5L, the dilution concentration of pesticides is about 15 times higher than that of artificial or mechanical spraying on the ground. The demand for pesticide formulations and the ...
