Thermal silica gel is mainly used in the heat conduction and heat dissipation function of heating components. The performance of ordinary thermal silica gel depends on the aluminum hydroxide content. Of course, special thermal silicone grease will be mixed with an appropriate amount of precious metal oxide. It is mainly composed of four components: polydimethylsiloxane, aluminum hydroxide,...

Reasons for foam concrete defoaming: 1. The foaming agent has poor foam stabilization performance. This is mainly because the foaming agent uses low-grade surfactants. 2. No slurry stabilizer is used in the slurry, so that the foamed lightweight soil slurry has no stabilizing effect on the foam, and the foam cannot be strengthened and consolidated after entering the slurry. 3....

1. The generation of bubbles in paint and the principle of bubble stabilization: In the production process of paint, air will be drawn into it to form bubbles. Certain raw materials in the paint, such as surfactants and dispersants, will stabilize the bubbles. Air bubbles will also be generated during the paint application process, which mainly depends on the paint application method....

Generally, after the silicone rubber manufacturers mold the silicone products, there is no time to pack them for a period of time, and the surface of the products will absorb a layer of dust or fibers, which greatly affects the appearance of the products. Therefore, silicone rubber manufacturers have taken corresponding measures to deal with the problem of easy adsorption of dust on...

The physical and chemical properties of high quality defoamers must meet the requirements of the use system. Generally speaking, the following requirements must be considered when choosing a defoamer: (1) Strong defoaming ability. It can effectively eliminate foam when using a very small amount; (2) It has a lower surface tension of the defoaming system, that is, the surface tension...

Before the emergence of low-temperature hot-melt adhesives, a chemical called Gangbao was similar to the use of low-temperature hot-melt adhesives. It could be used in the production of mattresses, sanitary napkins, diapers and other products. However, due to the development of the industry, life The improvement of the level and people's awareness is that we are pursuing environmentally...
