Description

Silica colloid production facility

Technical Field

The utility model relates to a production facility specifically is a silica gel production facility.

Background

Hydrolysis/condensation reactions with silanes are common methods for preparing silica colloids. It is conventional practice to produce the silane compound in a batch reaction by stirring water and the silane compound in a vessel until the reaction is complete. This method is slow and disadvantageous for mass production. The silane substance is not mutually soluble with water, and can form an obvious interface when coexisting, and the chemical reaction can only be carried out in the interface, so that the limited interface area is a main factor for limiting the reaction rate. In this regard, improvements are needed.
