    展柜應該具有良好密封性,內(nèi)部應當安裝有溫濕度自動測定儀器和控制濕度的設(shè)備。設(shè)備不準與展柜同體安裝。
     
      展柜控制濕度的第一種選擇是安裝去濕機。當濕度超過要求范圍時,濕度控制儀能自動開啟去濕機降低濕度并同時顯示報警信號。
     
      展柜控制濕度的第二種選擇是放置吸濕緩沖材料。此選擇要求在展柜下層箱體中留出足夠空間用于放置吸濕緩沖材料,例如硅膠。吸濕緩沖材料在夏天潮濕氣候下可吸收潮氣,在冬天干燥氣候下可放出水分保持展柜內(nèi)濕度穩(wěn)定。工作人員需要隨時根據(jù)氣候特點更換吸濕緩沖材料。展柜下層硅膠箱體應該和上層文物展出部分有足夠氣孔進行空氣交換。在展柜下層預留吸濕緩沖材料箱體的目的是為了在更換硅膠時應該不影響展柜中展品,即不需要移動展品。


    The display cabinets should be well sealed and equipped with automatic measuring instruments for temperature and humidity and equipment for humidity control. The equipment is not allowed to be installed with the display cabinet.
    The first choice for the display cabinet to control humidity is to install a dehumidifier. When the humidity exceeds the required range, the humidity controller can automatically turn on the dehumidifier to reduce the humidity and display the alarm signal at the same time.
    The second option for the display cabinet to control humidity is to place a hygroscopic buffer material. This option requires that enough space be left in the lower compartment of the display cabinet to place hygroscopic buffers, such as silica gel. The moisture absorbent buffer material can absorb moisture in the humid climate in summer, and can release moisture in the dry climate in winter to keep the humidity in the display cabinet stable. Staff members are required to replace moisture absorbent buffers at any time in accordance with climate characteristics. The lower part of the cabinet should have enough air holes for air exchange with the upper part of the exhibition. The purpose of reserving the wet-absorbing buffer material box body at the lower level of the display cabinet is that when replacing the silicone gel, it should not affect the exhibits in the exhibition cabinet, that is, there is no need to move the exhibits.
