采用塑料帐气调养护中药材,比常规养护成本低(南方10～20%,北方40～50%),但三分之二的费用花在塑料帐上。因此,改建成性能良好、成本低廉、管理方便、节省仓容的固定性和永久性的密闭库,是气调养护值得探索的一个问题。我们采取透气性很低的饱和聚酯塑料薄膜之一,加沥青于库房内壁作“两沥一塑”处理组成密闭层,再抹麻刀灰和白灰组成吸潮及光浩层,将旧库房改建成为密闭库,并作了气调养护中药材的试验。
The use of plastic account for gas conservation of traditional Chinese medicinal materials is lower than conventional maintenance (10 to 20% in the south and 40 to 50% in the north), but two-thirds of the costs are spent on plastics. Therefore, it is an issue worthy of exploration that air conditioning and maintenance are rebuilt into a fixed and permanent closed library with good performance, low cost, convenient management, and space saving. We adopt one of the saturated polyester plastic films with very low permeability and add asphalt to the inner wall of the warehouse as a “two-leaf and one-plastic” treatment to form a closed layer, then wipe the ash and white ash to form a moisture-absorbing and light-rich layer, and rebuild the old warehouse. Become a closed library, and made air conditioning maintenance of Chinese herbal medicines test.
