1. Advantages of natural oils (i.e. soybean oil, corn oil, etc.): easy source, low price,Simple to use; disadvantages: if the storage is not good, it is easy to deteriorate, so that the acid value increases, and it is toxic to fermentation.2. There are many kinds of polyether defoamers, mainly including the following: A. GP defoamer: it is made by addition polymerization of propylene oxide or mixture of ethylene oxide and propylene oxide with glycerol as the starting agent. GP defoamer has poor ...
Amino silicone oil is a basic component used in textile softener. It has the best adsorption, compatibility and emulsification. Using a mixer or homogenizer, the amino silicone oil is easily emulsified into a stable and transparent microemulsion by the appropriate surfactant. It can be used alone or combined with other organosilicon or organic softeners to form a special softener, which is suitable for the softening finishing of various textiles.Basic introductionAmino silicone oil is a basic co ...
1. What is silicone rubber. How is silicone rubber classified?Silica gel is a kind of highly active adsorption material, which is an amorphous material. It contains polysiloxane, silicone oil, silica, coupling agent and filler. The main component is silica, and its chemical formula is msio2 nH2O. Insoluble in water and any solvent, non-toxic and tasteless, stable chemical properties, no reaction with any substance except strong base and hydrofluoric acid. Different types of silica gel have diffe ...

The common function of coupling agent is to establish compatibility between organic and inorganic materials. For example, to improve the dispersion of nano calcium carbonate in polymer, coupling agent and surface treatment are needed. The introduction of organic groups on the surface of inorganic materials makes it much more compatible with polymers and reduces the problems of migration, precipitation and agglomeration.This is similar to block polymer or graft polymer (such as graft maleic anhyd ...
Leather brightener is made of high-quality organic silicon. It is a water-soluble oil brightener. The leather brightener has a smooth and delicate feel (oily feeling), with high brightness and smoothness. This product is resistant to high temperature and low temperature. It does not contain solvent and does not stick to leather. It can increase the handle of leather products, make them softer and more natural, and make the leather smooth and delicate. The leather products are endowed with excell ...
Wool is one of the earliest textile fibers used by human beings. It has many excellent characteristics, such as smooth handle, good warmth retention and comfortable wearing, but it is easy to pilling. Silicone softener is widely used in wool fabric softening finishing. It can change the friction coefficient of wool fiber and improve the pilling resistance of wool fabric. However, it has poor hydrophilicity and easy to produce static electricity, which affects the wearability. The first generatio ...

surface tension of waterThe surface tension of water is 72 nm / cm at room temperature and has little change with temperature. The surface tension of these materials can be determined by the surface tension of the materials, such as water. If the water drops on the surface of plastic or lotus leaf, we call it non wetting, or poor wetting. On the contrary, if the water drops spread evenly on the surface, it shows good wetting effect. In the process of our life and production, the surface behavior ...
