The modified silicone oil introduces methyl silicone oil with a part of hydrophilic polyether segment, which can be turned into a self-emulsifying defoamer, which can maintain dispersion for a long ti......
2020-04-01The solid silicone defoamer has the characteristics of good storage stability, easy transportation, and convenient use. It can be used not only for the production of non-foaming and low-foaming laundr......
2020-04-01The silicone oil or silicone paste is strongly stirred or emulsified to make a silicone oil emulsion, which can effectively improve the dispersibility of the silicone oil in the water phase. It is wid......
2020-04-01Oil type antifoaming agent is directly used silicone oil as an antifoaming agent. It is mainly used in oil-phase foaming systems that do not allow the presence of dispersants and emulsifiers. It is ge......
2020-03-31advantage: 1) Wide application: Due to the special chemical structure of silicone oil, it is neither compatible with water or materials containing polar groups, nor with hydrocarbons or organic mater......
2020-03-31There are four preparation methods of emulsifiers, namely dry glue method, wet glue method, oil phase water phase mixing method, and mechanical method. Dry glue method, that is, the water phase is ......
2020-03-31Hydrophilic-lipophilic balance (HLB) Generally, the emulsifier with strong hydrophilicity becomes an oil / water type emulsion, and the emulsifier with strong lipophilicity becomes an water / oil t......
2020-03-31Food emulsifiers are also called surfactants, or substances that turn incompatible liquids into uniformly dispersed phases (emulsions). When added to food, they can significantly reduce the interfacia......
2020-03-31In mold design, there are generally the following forms: 1) Hot runner More wasteful materials, simple design, low cost, mostly used for large products. 2) Cold runner with needle valve Can realiz......
2020-03-30The following forms are available: 1) Two-way pump The feed can be moved up and down, which can keep the pressure well. Because the A and B pumps are connected and synchronized by Hydraulic and p......
2020-03-30LSR is a two-component liquid material, which is divided into A component and B component. The work of the mixer fully mixes A component and B component in a precise 1: 1 ratio. Because some products ......
2020-03-30Liquid Silicone Rubber, or LSR, is a non-toxic, heat-resistant, high-recovery, flexible thermosetting material. Its rheological behavior is mainly characterized by low viscosity, rapid curing, thinnin......
2020-03-30Methyl silicone oil is one of the earliest commercialized, most widely used and most commonly used silicone polymers. There are two main methods for producing methyl silicone oil: acid balance method ......
2020-03-30(1) Ordinary water reducing agent: Under the condition that the slump of the concrete is basically the same, it can reduce the amount of water for mixing. (2) High-efficiency water reducing agent: Un......
2020-03-28I. Classification by main function (1) Additives to improve the rheological properties of concrete mixtures, including ordinary water reducers, high-efficiency water reducers, early-strength water re......
