De acuerdo con la estructura química y propiedades de los productos categorizado -- 2017-01-20

Many types of polysiloxane, according tothe product's chemical structure and performance can be divided into threecategories:1. Silicone oil, low molecular weight linear structural polymer.Colorless or light yellow transparent liquid with high boiling point and lowfreezing point, thermal decomposition and particularly stable against water oroxidizing agents. Can be used as hydraulic oil, high-grade lubricants, surfacetreatment and demulsifier, can also be used as textiles, paper and many otherma ...

The step of constructing the siloxane chemical structure -- 2017-01-19

The step of building the chemical structureof the siloxane is the process of determining the length of the polymer chain,branching, and insertion of the organic group. From the point of view of itschemical structure, the structural groups entering the molecule are representedby the letters M (monofunctional), D (difunctional), T (trifunctional) and Q(tetrafunctional). The M functional groups are chain terminating because theyare monofunctional; the D functional group is a linear increment, makin ...

Siloxane compounds -- 2017-01-18

Siloxane compounds were well known in the1960s, but it was not until the 1940s that Dr. Eugene RoChow pioneered the workof commercializing such important compounds. The chemical nature of siloxanesallows polymer chemists to build accurate molecular structures using idealnanotechnology. The siloxane polymer is derived from silica (Si02), whichaccounts for 25% of the total crust. In the presence of a carbon source, thesilica is converted to a siloxane at elevated temperatures. The resulting metali ...

Polysiloxane -- 2017-01-16

There are few silicone-free compounds inthe new cosmetic formulations, and the use of silicone compounds in personalcare products has achieved significant growth. In addition, even with the mostadvanced technology of the formulator, still inevitably use siloxane.Silicone polymers consist of differenttypes of compounds, including conventional silicone oils, water-solublepolymers, oil-soluble polymers, fluorine-soluble polymers, and polymers withvarious solubility. They exist in a variety of forms ...

Siloxane esters -- 2017-01-13

The final action to be considered is thederivatizing reaction. In this step, the reaction group added to the functionalaction step is further reacted to give a new compound, and the reaction of thehydroxyl group with the polydimethylsiloxane copolymer polyol is an example ofsuch a reaction. In fact, a series of surface-active siloxanes, comparable to alarge number of standard surfactants, have been developed and marketed.Silicone esters are an excellent example of the effect of derivatization on ...

Surface Tension -- 2017-01-11

Surface tension is the main driving forceof coating leveling, but the surface tension difference, but it is the maincause of surface defects. To improve the surface tension of the coating toachieve the surface tension balance, which is the flow of the coating andleveling is very useful, but it can’t. So people had no choice but to reducethe surface tension of the coating to eliminate surface tension difference,control the surface state of the coating to eliminate surface defects. Such asthe eli ...
