2019-12-09An important indicator of the quality of the defoamer is its dispersion effect. Only those with low solubility and large dispersibility can become the active ingredients of the antifoaming agent. As t......
2019-12-09Hydrophobic fumed silica is produced by a chemical reaction between a hydrophilic fumed silica and an active silane (such as chlorosilane or hexamethyldisilazane). It is hydrophobic (hydrophobic) and ......
2019-12-09Hydrophilic fumed silica is produced by the hydrolysis of volatile chlorosilanes in a hydrogen-oxygen flame. From a chemical point of view, these loose white powders are composed of high-purity amorph......
2019-12-09Generally, silicone oil with a large molecular weight is insoluble in a surfactant solution, and for small molecular weight silicone oils, it is easily solubilized by surfactant molecules, thereby cha......
2019-12-06Certain low-molecular substances that can be thoroughly mixed with the solution can solubilize the surfactant of the bubble and reduce its effective concentration. Low-molecular substances such as alc......
2019-12-06In the foaming water system, the addition of hydrophobic silica (ie, hydrophobic white carbon black) particles alone has a defoaming effect. The hydrophobic white carbon particles will attract the hyd......
2019-12-06Because the surface of the bubble film adsorbs the surfactant, the surface tension is reduced. Therefore, under local pressure, the bubble film becomes thinner at the same time, and the surface tensio......
2019-12-06Someone has studied the defoaming process of polysiloxane in the oil system.They continuously take pictures of the foam system at a speed of 1/1000 second, the picture is enlarged 100 times, and the s......
2019-12-06The main components of white carbon black and silicon powder are the same, both are silicon dioxide, both have stable properties, while white carbon black is made of silicon dioxide by vapor depositio......
2019-12-05Silica, also known as light silica, has a scientific name of precipitated hydrated silica. Is a high-tech inorganic fine chemical product, the main ingredient is SiO2. The performance is similar to ca......
2019-12-05Silica is a highly dispersed amorphous powder or a flocculent powder, which is lightweight and has high electrical insulation, porosity, and water absorption. Its original particle size is less than 3......
