How to choose desiccant bottle

Jun 25 , 2019

According to the characteristics of the test paper, a large part of the test paper bottles are used moisture-proof design, the top with a desiccant medicine warehouse, in order to ensure that the test strip in the packaging of air drying, to ensure the effectiveness of the detection effect.

How to choose desiccant bottle

desiccant bottle

General paper packaging desiccant selected mostly silica gel, because silica gel desiccant can continue to effectively absorb water molecules inside the package.It depends on the chemical molecular formula and adsorption mode of paleo drying agent.Silica gel desiccant is a highly active adsorption material with its chemical molecular formula and as mSiO2·nH2O.Insoluble in water, non-toxic and tasteless, chemical stability, according to the size of the pore size of silica gel is divided into: macroporous silica gel, coarse pore silica gel, B-type silica gel, pore silica gel.Silica gel can be reused after regeneration.The main component of silica gel desiccant is silica, mostly translucent amorphous, made of natural minerals processed into granular or beaded, usually formed after treatment with sulfuric acid, its hard texture, non-toxic, tasteless, non-corrosive, there is a strong chemical stability and thermal stability.

There is also a part of the blood glucose test strips packaging desiccant choose a mixture of silica gel and molecular sieve, but the surface of the silica gel desiccant cover many hydroxyl groups, has a strong hydrophilic, while the surface of the silica gel desiccant has many holes invisible to the naked eye, so that the surface area is greatly increased,Desiccant good shelf life most suitable for the moisture environment temperature 20 ~ 32, humidity of 60% to 90%, it can reduce the relative humidity of the environment to 40%.
