Silica sol (ND-CS series)
We can produce super purified Silica sol, we are good at produing Silica sol, Silica sol is our special. It's CAS is 112926-00-8
Silica is silicon dioxide nano-particles in the water or solvent in the sub-spreading liquid. As a result of the SiO2 Sol contains a lot of water and hydroxyl, it can also be expressed as silicasol SiO2. NH2O. Preparation of silica sol with different ways. The most commonly used method of ion exchange, silica fume hydrolysis step, such as silane hydrolysis. These raw materials used in different processes are taking different routes, and the final product performance and production costs are also different. Silica for the ion exchange process NALCO U. S. 40 in the last century's development, by DuPont, such as the United States in the fifties and sixties perfect, is currently the most mature and most widely used technology. The process of water glass, ion-exchange resins, such as materials, and operation requirements of a certain process, which is what products of the disadvantaged. On the other hand, silica fume hydrolysis step of the process is relatively simple. However, with the silica sol is usually prepared in the 10-20 nanometer particle size around the interface between particles is not clear, non-spherical morphology and can not control the interface between particles is not clear, it is usually only large-scale use in the foundry industries, and in precision polishing, catalyst and many other demanding little contribution to the field. Silica and international well-known brand compared to the current domestic Sol for the main disadvantage of the high impurity content, without strict control of particle size, particle surface area not subject to strict testing, the concentration of low-silica, acidic or neutral conditions, the stability of difference, the use of short cycle, a bit more or less color, fewer species and so on.

Our silicasol company for a new synthesis of sol-gel method of preparation, the method of our own knowledge property rights. We can accurately control the number of characteristics of silica sol, such as: Particle morphology from spherical to dumbbell-shaped or chain, the concentration of up to 60% of solid content (30-40% under normal circumstances), particle size 10 nm from the following to the micron level (typically 10-100 nm), all kinds of impurities can be controlled to the ppb level or below 100 1/10000, SiO2 particles can be big or small, dispersion media can also be water and other non-alcohol water solvent, pH can be neutral can also be acidic or alkaline. Compared with the international well-known brands, our products more cost-Sol, equal or superior performance.
Categorized by type, produced by our company can be divided into the following categories silicasol
We have different applications according to the customer different demand for different products. At the same time we also welcome customers to our own different technical requirements.
