Is silica gel environmentally friendly?

Silica gel is a porous material with different particle sizes formed by proper dehydration of silicic acid gel. It has an open porous structure and can adsorb many substances. It is a good desiccant, adsorbent and catalyst carrier. 　　 Silica gel is a granular, glass, porous form of silica prepared from synthetic sodium silicate. Silica gel is tough and hard; more solid than ordinary household gels like gelatin and agar. It is a naturally occurring mineral refined and processed into either granular or beaded form. As a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules. Food-grade silica gel is non-toxic, tasteless, insoluble in water and any solvent, and is a highly active green product. Food-grade silica gel has inherent thermal stability (-40°C-230°C). It is suitable for different occasions. The product has good flexibility and meets different needs. 　　The raw materials of silica gel are divided into: ordinary industrial silica gel, food-grade silica gel, and platinum-grade silica gel. Ordinary silica gel is used to make miscellaneous industrial accessories, food-grade silica gel is used to make daily necessities and small accessories, and platinum silica gel is used to make high-performance silica gel products. Platinum is a vulcanizing agent to enhance the performance of various products as a catalyst. However, whether it is ordinary or food grade, it can be used with peace of mind. Silicone is colorless and odorless. Adding various color gums and mixing to make a variety of bright colors makes us think that its bright colors are poisonous! 　　The characteristics of silica gel: 　　1. High temperature resistance: The applicable temperature range is -40 to 230 degrees Celsius, and it can be used in microwaves and ovens. 　　2. Easy to clean: The silica gel products produced by silica gel can be cleaned after being rinsed in clean water, and can also be cleaned in the dishwasher. 　　3. Long life: The chemical properties of silica gel are very stable, and the products made have a longer life than other materials. 　　4. Soft and comfortable: Thanks to the softness of the silicone material, the cake mold products are comfortable to the touch, very flexible and not deformed. 　　5. Variety of colors: According to the needs of customers, different beautiful colors can be deployed. 　　6. ​​Environmental protection and non-toxic: no toxic and hazardous substances are produced from the raw materials entering the factory to the finished product shipment. 　　7. Electrical insulation performance: Silicone rubber has a high resistivity, and its resistance can remain stable in a wide temperature range and frequency range. At the same time, silica gel has good resistance to high-voltage corona discharge and arc discharge, such as high-voltage insulators, high-voltage caps for TV sets, and electrical components. 8. Low temperature resistance: The lowest temperature critical point of ordinary rubber is -20 degrees to -30 degrees, but silicone rubber still has good elasticity from -60 degrees to -70 degrees. Some specially formulated silicone rubbers are still Can withstand extremely low temperatures, such as low-temperature sealing rings. 　　9. Conductivity: When conductive fillers (such as carbon black) are added, silicone rubber has good conductivity, such as keyboard conductive contact points, heating element parts, antistatic parts, shielding for high-voltage cables, conductive film for medical physiotherapy, etc. 10. Weather resistance: Ordinary rubber is rapidly degraded under the action of ozone generated by corona discharge, while silicone rubber is not affected by ozone, and its physical properties have only minor changes under ultraviolet light and other weather conditions for a long time, such as outdoor Sealing materials used, etc. 　　11. Thermal conductivity: When some thermal conductive fillers are added, silicone rubber has good thermal conductivity, such as heat sinks, thermally conductive gaskets, photocopiers, fax machines, heat transfer rollers, etc. 　　 12. Radiation resistance: The radiation resistance of silicone rubber containing phenyl groups is greatly improved, such as electrically insulated cables and connectors for nuclear power plants.
