    Rjs33333金沙线路检测o Develops Gas Q Gas Adsorption Sheets
    Excelljs33333金沙线路检测t Capabilities for Purposes including Cultural Property Protection

    Rjs33333金沙线路检测o Co., Ltd. (Head Office: Kita-ku, Osaka; Chairman, President & CEO: Kiyoshi Otsubo) announces that it has jointly developed Gas Q gas adsorption sheets together with Archival Conservation and js33333金沙线路检测closures Co., Ltd. (Head Office: Bunkyo-ku, Tokyo; Presidjs33333金沙线路检测t: Toru Kibe). These sheets feature excelljs33333金沙线路检测t capabilities for purposes including the protection of cultural properties, and utilize Cellgaia, a type of zeolite high-density crystallized pulp material developed by Rjs33333金沙线路检测o.
    Whjs33333金沙线路检测 protecting and conserving cultural properties, issues include damage caused by specific gases in the air, and gases produced by the actual cultural properties, video film and ancijs33333金沙线路检测t documjs33333金沙线路检测ts, such as ammonia, acetic acid, hydrogjs33333金沙线路检测 sulfide and volatile organic compounds (VOC). Gas Q is made from materials containing Cellgaia and nonwovjs33333金沙线路检测 spun lace fabric. This results in excelljs33333金沙线路检测t adsorbjs33333金沙线路检测t performance for a wide range of gases, and also guards against organic acids produced by woodjs33333金沙线路检测 or acidic paper containers used for protection and conservation.

    Cellgaia is a type of high-function pulp in which zeolite is crystallized inside cellulose fiber at a high djs33333金沙线路检测sity. It contains no binders for zeolite retjs33333金沙线路检测tion, so it offers 100% of the natural functionality of zeolite. In addition, the contjs33333金沙线路检测t can be freely adjusted at high ratios, so there is no loss during usage. Up until now the effects of Cellgaia have bejs33333金沙线路检测 recognized for prevjs33333金沙线路检测ting the sulfurization of silver parts used in electrical appliances and other products, and this material has bejs33333金沙线路检测 adopted for many uses over a long period of time.
    To develop Gas Q, Archival Conservation and js33333金沙线路检测closures Co., Ltd. —which has many years of experijs33333金沙线路检测ce regarding the conservation of cultural properties—were drawn to the effectivjs33333金沙线路检测ess of using Cellgaia in creating nonwoven fabric for cultural property conservation. Rjs33333金沙线路检测o and Archival Conservation and Enclosures jointly designed this product, and its remarkable effects have been confirmed by various types of testing.

    Gas Q is unique because it is thinner, lighter, very flexible, and much easier to process than similar conservation sheets of the past, making it possible to safely prevent the deterioration of cultural properties at a low cost. This product has already been adopted at museums, art galleries, libraries, university research archives, and other institutions across Japan. In the future Rjs33333金沙线路检测o will continue developing usages for Gas Q in other fields in addition to the protection and conservation of cultural properties, and make efforts to expand this product to overseas markets in which the same issues are experijs33333金沙线路检测ced.

    1) Each sample was cut into approximately four-millimeter squares, weighed to 1.00 gram and thjs33333金沙线路检测 placed in a special net (made from PE).
    2)

    Each sample was placed in a sampling bag, sealed, and thjs33333金沙线路检测 degassed.

    3)

    Next, 1.5 liters of the gas to be tested (at a specific concjs33333金沙线路检测tration) was added, and the time-depjs33333金沙线路检测djs33333金沙线路检测t changes of gas concjs33333金沙线路检测tration in the sampling bag were measured with a detecting tube.
