Qingdao Hengze Silica Gel Products Co., Ltd was established in 2014. We have been dedicating to the research, production and sales of silica gel. Our silica gel is widely used in various industries such as gas and oil industry, food, bio-pharmaceuticals, plant extraction, fine chemicals, scientific analysis, environmental monitoring, petrochemicals, and also daily life. We have been cooperating with some research institutions and universities in China. After a few years' development, we expanded our business scope to other chemical industries. Our main products include silica gel desiccant, indicating silica gel, column chromatography silica gel, catalyst silica gel, oil decoloring silica gel, FNG silica gel, silica alumina gel, molecular sieve, activated alumina...Our annual production is about 20,000 tons.
Colloid Silica/Silica Sol
* Characteristics
Silica sol is a colloid formed by silica nano particles in water, odorless, non-toxic, milky white color. Fine silica colloidal particles size is 10-20nm with high specific surface area. The particles are transparent, so they will not affect the color of the covered material. If mix silica sol with other substances, the dispersion and permeability are very good. When the silica sol evaporates, the colloidal particles firmly adhere to the surface of the material and form silica-oxygen bonding between the particles, which is a good adhesive.
* Application
It is widely used in precision casting, paper-making, textile, coating and refractory industries. It is also used in silicon steel sheet treatment agent, battery solid electrolyte, catalyst carrier, anti-skid agent, etc.
