The physical and chemical properties: yuan jiang card - fumed silicawithWith small particle size, large specific surface area, high structural, have very strong reinforcing properties, silicon dioxide on the surface of the silicon alcohol-based (Si - OH) and silicone rubber molecules can form the physical or chemical combination and formation of silicone rubber molecules adsorbed layer in the surface of silica, silica and rubber particles molecular got behind one of the three dimensional network structure, so as to achieve reinforcement effect.Silicone rubber bullishness of phase silica after reinforcement, the intensity of the highest increase up to 40 times。
use：Ink, silicone rubber, tablets, cosmetics, plastic, paint, medicine and other fields。
Medicine:Thickening, suspension, carrier role, but also can be used as pesticide powder and an anti-caking agent.
The paint coating:Is a kind of additive, prevent the stability of the pigment to precipitate.Often use it to change the thixotropy, adjust viscosity.It is colorless transparent state in the varnish.In many of the coating can improve the flow property, to prevent its crust, affect the effect of electrostatic spraying.Also can control some paint gloss, such as urethane polishing processing.
Adhesive:In the sealant, adhesive.Be regarded as a kind of thixotropic agent, is used to control material precipitation.Moreover it is viewed as a reinforcing material.For those who adopt high-speed production of industrial adhesive method, has a special purpose.It makes the automation system suitable for a wider range of temperature change.
Polyester resin and rubber coagulation (gel) :The extensive use of the polyester resin, the polyester resin is used for production of trucks for boats, roof and other layers.In the layered resin as reinforcing agent can prevent resin flow.In terms of gel layer, the reinforcement effect can prevent substance precipitation, increase the thickness of the thin film layer and appearance.The putty and repair can be controlled in polish consistency, flow rate and stirring soluble to meet different needs.
Rubber and synthetic rubber:One of the most important purpose is synthesis of silicone rubber.After reinforcement of silicon rubber, the strength up to a few times, high temperature resistance and chemical resistance are also greatly improved, make silicone rubber applications more widely.
