At NINGBO INNO PHARMCHEM CO.,LTD., we understand that the effectiveness of our products is rooted in sound scientific principles. Our silica gel, widely used in oil purification and waste oil recycling, owes its remarkable performance to its unique physical and chemical properties.

Silica gel, chemically known as silicon dioxide hydrate (SiO2·nH2O), is a porous granular material. Its effectiveness as an oil purification agent stems from its incredibly high surface area, which can be as large as 800 square meters per gram. This vast internal surface area is riddled with microscopic pores, creating a matrix that is highly effective at adsorbing impurities and color bodies from various oils.

When we talk about silica gel for waste oil recycling, its primary function is often as an oil bleaching agent. The polar nature of the silica gel surface interacts with polar impurities and color-causing molecules present in oils like diesel oil or pyrolysis oil. These interactions lead to the molecules becoming physically trapped within the silica gel's pore structure – a process known as adsorption.

The mechanism is akin to a molecular sieve. As the oil passes over or through the silica gel, undesirable components are preferentially adsorbed onto the silica surface, leaving the oil cleaner and brighter. This is why silica gel is so effective in applications such as silica gel for diesel oil bleaching or as a pyrolysis oil bleaching agent. The strong absorption capacity ensures that even deeply colored oils can be significantly decolored.

Furthermore, the scientific integrity of silica gel also extends to its reusability. Under controlled conditions, the adsorbed impurities can be desorbed, allowing the silica gel to be regenerated and used again. This cyclic nature, typically allowing 2-3 uses, is a crucial aspect of its cost-effectiveness and contributes to its environmentally friendly profile. For businesses seeking to buy silica gel for oil purification, understanding this underlying science validates its selection as a superior chemical auxiliary.

NINGBO INNO PHARMCHEM CO.,LTD. is proud to offer silica gel products backed by scientific excellence, ensuring optimal performance for your oil purification needs.
