Summary:
Nano silica product is an amorphous white liquid powder with a variety of specific surface area and volume size distribution. This product is a white, loose, amorphous, non-toxic, tasteless, no smell, no pollution of non metal oxides. The primary particle size is between 7 and 80nm, and the specific surface area is more than 200m2 / g. Because of the nano effect, the material exhibits excellent reinforcement, thickening and thixotropic, insulation, extinction, antidripping properties, so it is widely used in rubber, plastics, coatings, adhesives, sealants and other polymer industry.
Technical index:
The content of water is less than 0.01: 99.99%
Use:
1. Thickening agent and thixotropic agent and resin coating.
2. Flatting agent: furniture paint development trend to Matt, a column varnish or paint can be used ultrafine silica gel products as flatting agent, in addition, coil coating PVC, plastic wallpaper, raincoat tents and flatting agent can also use such products.
3. Polyethylene, polystyrene, non-toxic PVC film anti blocking agent / agent.
Application in polymer industry:
1. In the application of rubber: reinforcing silicone rubber, the best effect is the gas phase silica. When the gas phase silicon dioxide is added, the strength can be increased by 40 times, the yield point modulus can be increased by 1O times, the elongation at break and creep property can be improved greatly.
2. In the application of sealants and adhesives can be used as thickening agent and thixotropic agent, can increase the bond strength, guarantee the freedom of movement, and can prevent caking during curing of the flow, collapse of scattered, sag, transparency, reinforcement, shear effect.
3. In the application of plastic: can improve the density of plastic products, finish and wear resistance. In the same time, it can achieve the purpose of strengthening and toughening of plastics by appropriate surface modification. The fumed silica added to the polyethylene, through a special method, can make the silica dispersed uniformly in the matrix, prepared with high wear resistance.
4.Inthe thixotropy of polyester and gel resin application: the product is more uniform thickness, small shrinkage, more in line with the design requirements.
5. In the application of atomic ash: with anti thixotropy settling effect and excellent good.
6.application in coatings: anti caking and anti sagging, emulsification, extinction, suspension, thickening and thixotropic function etc..
