How Is Activated Carbon Desiccant Produced?

How is Activated Carbon Desiccant produced?

Activated Carbon Desiccant is a highly active adsorbent material, which is the most commonly used Activated Carbon Desiccant. The chemical molecular formula of the non-crystalline substance is mSiO2. NH2O. It conforms to the Chinese chemical standard HG/T2765-2005. It is an Activated Carbon Desiccant that is approved by the FDA for direct contact with food and medicine. Activated Carbon Desiccant has a strong moisture absorption ability, strong adsorption performance, even if the Activated Carbon Desiccant is immersed in water, it will not soften or liquefy. It has the characteristics of non-toxic, tasteless, non-corrosive and pollution-free, so it can be in direct contact with any object.

The production process of Activated Carbon Desiccant, the raw materials that need to be prepared are: sodium silicate (foam alkali, water glass), sulfuric acid.

Mix good alkali and acid in advance, and then the solid sodium silicate with high temperature melt and filtering, makes a certain concentration of liquid, then makes a certain concentration of sulfate liquid, sulfuric acid concentration was 20%.

Second, Activated Carbon Desiccant the second step for making plastic granules (gel), this is the most critical step, will be prepared in advance bubble spent lye and sulfuric acid reaction under specific conditions, to form soluble gel solution, after reaching the appropriate concentration will become gel particles. The shape and size of the granules can be determined according to the user's requirements and production capacity. The method of gels is generally common in weiqi granule, the ratio of acid and alkali, concentration, temperature and gelation time of gels are specific process parameters of gel granulation process.

Three, Activated Carbon Desiccant aging of gel required to pass through a certain amount of time and temperature, and PH value to aging, makes the gel skeleton, strong glue condensation between particles in the process of aging Si - O - Si key, strengthen the skeleton strength, particle near each other, smaller space truss structure in space, and contains water part of extrusion.

4. Pickling, Activated Carbon Desiccant washing and cleaning

Pickling, washing, and cleaning are also important steps in the process of cleaning up the Na2SO4, which is formed by granular gels. Control the anions to the process requirements.

It can be said that the hole characteristics of the finished silica gel is a large part of the aging process of the washing process, and the aging of the process depends on the operation in the process of pickling, washing and cleaning.

5. Activated Carbon Desiccant, will make good water gel (after washing) into the oven, and the water content of the gel itself will be dried to the required range in certain conditions. The higher the drying temperature, the greater the speed of a particle gathering and the larger the aperture.

6. Screening, using the selecting ball machine, the silica gel produced after drying will be filtered through the mesh of different aperture, and the broken silica gel will be filtered out simultaneously.

7. Picking glue: Activated Carbon Desiccant after picking out the heterochromatic balls and impurities in silica gel, the paper will be packed and sealed after using the compound paper.

Activated Carbon Desiccant is cheap, durable, light, non - toxic and oil - proof. In addition, the aluminum foil can be cut off many chemicals, bacteria, water and gas, and has a good barrier for electromagnetic characteristics and non-magnetic, and therefore under seven microns thin aluminum foil in the flexible packaging industry has become more and more popular, especially in the field of food packaging. But aluminum foil coil, because it is too thin, if be affected with damp be affected with damp in the process of storage and transportation, extremely easy oxidation (white spot), so the moisture-proof measures is very important for aluminum coil, ChunWang for solving aluminum moisture-proof have rich experience, with aluminum more than domestic well-known enterprises such as sheng tong reached a long-term strategic cooperative relations, our Activated Carbon Desiccant moisture absorption rate is high (> 30%), safe, stable chemical properties, contact with aluminium won't has the negative effect such as corrosion, using medical grade leakproof O cloth packaging, unique technology, pressolution sealing side firmly, don't break, don't leak.
