BD®--1, BD®-2 clay desiccant is made of the natural bentonite mineral as the raw material by the special process purifying. This new desiccant has high quality and reasonable price. It can replace (or partly replace)the silica gel desiccant. With the stable chemical property, this bentonite desiccant is non-poisonous and odorless. It doesn't pollute the environment, can be regenerated or used repeatedly.

1.Application:

          It is apply to the damp-proof, moisture-absorbing and mould-proof of the sealed package of the products for military and industry (e.g.: ammunitions, weapons),as well as the products for civilian use (eg: apparatus, instrument, electronic products, medicine, books, food, clothes)

2.Technical characteristic

(1)High percentage of moisture adsorbance:(BD®--1>30%、RH=40%;>17%、RH=20%/BD®-2 : >20%、 RH=40%; >12%、RH=20%)

(2)Quick speed of adsorbing

(3)Besides moisture, it can adsorb other pernicious gas (e.g.: formaldehyde) and strange smell(e.g.: ammonia)

(4).Non-poisonous, odorless, non-pollution, non-corrosion and non-radiation

(5).It can be used repeatedly without decrease of the moisture-absorbing percentage

(6).Pernicious element content: As=10ppm,Pb=30ppm,which is lower than the food standard (As=10ppm、Pb=40ppm、Hg=40ppb)
