Silicone is in a liquid state and has flowability. It is a highly transparent and safe food grade material that does not add auxiliary materials such as vulcanizing agents during molding, and is sealed and fed for molding. Solid silica gel is in a solid state and has no fluidity. It is also a transparent and environmentally friendly material that requires the addition of a vulcanizing agent to accelerate the vulcanization molding time and open mold feeding for molding. What is the difference between solid silicone and liquid silicone that the editor will introduce today?
Liquid silicone is injection molded liquid silicone rubber (LSR): its full name is injection molded liquid silicone rubber, and the vulcanization equipment is an injection molding machine. The injection molding machine has a very simple process flow (without the need for manual processes such as ingredients, rubber mixing, cutting, and placement in the high-temperature glue process, only one worker is required to pick up the product), high product accuracy (all manual procedures before molding are replaced by machines), high production capacity (A/B glue is mixed at a certain temperature for a few seconds to form), and multiple advantages such as saving manpower, electricity, and materials. It can produce all products produced by high-temperature glue.
In industry, solid silica gel is made of water glass (sodium silicate) as raw material, which is hydrolyzed in acid medium to produce gel, and then through aging, washing, drying and other processes to produce silica gel. According to the different water content, it is a translucent or white solid. Commercial products include irregular granular, spherical, and microsphere shaped silica gel, which is commonly used as a catalyst carrier in fluidized bed operations.
