1 application of desiccant in small package
According to the different scope of application, the varieties and packaging materials of small packaging desiccant are also different. From its contents: silica gel desiccant, alumina desiccant, natural active desiccant, drying sheet, drying paper, etc. It is widely used to control the relative humidity of the environment during the storage and transportation of food, medicine, electronic products, household appliances, handicrafts, instruments, clothing, shoes and hats, etc., and to prevent items from being damp, moldy or rusty.
2 the use of natural active desiccant
Bentonite desiccant is aluminosilicate with montmorillonite as the main component, which is a natural rare clay mineral with special crystal layer and is purified and processed by special technology. Its layered tetrahedron and octahedral wafer are arranged in hexagonal grid, which has the ability to absorb hydrated cations, cause lattice expansion after water absorption, and have the functions of moisture absorption, oxygen removal, freshness preservation, moth prevention and long-term effect. It is a new, healthy, green and pure natural mineral desiccant.
Features: pure natural, non-toxic, pollution-free, without any chemical additives.
Can be used as medicine, detoxification, detoxification drugs
Can be used as a feed additive, has a slow release effect in agricultural fertilizers and chemical fertilizers, and improves fertilizer efficiency.
High bulk density, high volume moisture absorption rate and low cost.
Non-corrosive to metal products.
3 the use of molecular sieve
Brief introduction: A- potassium type is an alkali metal aluminosilicate, which can adsorb molecules with a critical diameter of 3A.
Uses: Unsaturated hydrocarbon materials; Dehydration of industrial gases such as petroleum pyrolysis gas, ethylene, propylene, butadiene and acetylene; Polar liquid: drying of methanol and ethanol; Air drying and refrigerant drying in insulating glass; Food and carbon dioxide gas drying.
Regeneration: regeneration can be carried out by increasing the temperature of regeneration gas, purging or heating and vacuumizing, which can be reused. The efficiency of regeneration dehydration is related to the temperature of regeneration gas.
4 Use coarse pore silica gel
The appearance of macroporous silica gel is milky white, and there are three products: block, ball and microsphere. It is mainly used as a catalyst carrier; Because of its selective adsorption, it can remove harmful elements in water and organic acids in insulating oil, and can also be used as dehydrating agent and drying agent.
Step 5 use fine pore silica gel
The appearance of fine pore silica gel is white translucent glass, which is mainly used for drying, moisture-proof and rust prevention, and can also be used as catalyst carrier and dehydration and refining of organic products.
6 the use of blue silica gel
Properties: Blue silica gel is divided into blue gel, color-changing silica gel and blue gel indicator, and its appearance is blue translucent glass-like. As a moisture absorbent, it not only absorbs moisture, but also changes its color from blue to red with the increase of moisture absorption, so as to show the humidity change of the medium in the sealed packaging space. It is generally used to dry sealed packaging items, and can also be used with fine pore silica gel.
Use:
1 It is mainly used for moisture absorption and rust prevention of instruments, meters and equipment under sealed conditions. At the same time, it can directly indicate the relative humidity of the environment by changing the color from blue to red after moisture absorption.
2, with ordinary silica gel desiccant, indicate the degree of moisture absorption of desiccant, judge the relative humidity of the environment. As a silica gel desiccant for packaging, it is widely used in precision instruments, meters, leather, shoes and hats, clothing, handicrafts, food, medicines, household appliances and so on.
7. Use of activated alumina
Product structure: this product is a white spherical particle, a porous substance with a large number of adsorption surfaces inside. It is a new desiccant with unique performance, which has been treated by special technology to make its crystal structure stable.
